Features of scientific knowledge in medicine.
Diagnostics(Greek diagnō stikos capable of recognizing) - a branch of clinical medicine that studies the content, methods and successive steps in the process of recognizing diseases or special physiological conditions. In a narrow sense, diagnosis is the process of recognizing a disease and evaluating individual biological features and the social status of the subject, including a targeted medical examination, interpretation of the results obtained and their generalization in the form of an established diagnosis.
Diagnostics as a scientific subject it includes three main sections: semiotics; methods of diagnostic examination of the patient, or diagnostic equipment; methodological foundations that determine the theory and methods of diagnosis.
Methods of diagnostic examination of the patient are divided into basic and additional, or special. Historically, the earliest diagnostic methods include the main methods of medical research - anamnesis, examination of the patient, palpation, percussion, auscultation. Special methods are developing in parallel with the development of natural sciences and medical knowledge; they determine the high potential of diagnostic capabilities, including research at the subcellular level and the processing of medical data using a computer. The practical use of special diagnostic methods is determined by modern requirements for clinical diagnosis based on the nosological principle and including etiological, morphological, pathogenetic and functional components, which should characterize the features of the onset and course of the disease with sufficient completeness. Of the special methods are widespread X-ray diagnostics, radionuclide diagnostics , electrophysiological studies (including electrocardiography, electroencephalography, electromyography), methods of functional diagnostics, laboratory diagnostics(including cytological, biochemical, immunological studies, microbiological diagnostics). In large hospitals and diagnostic centers, highly informative modern special methods are used - computer tomography, ultrasound diagnostics, endoscopy . Laboratory equipment, reagents and test results are subject to periodic special checks in order to control the quality of laboratory research. Diagnostic instruments and devices should also be subject to metrological control to ensure accuracy, reproducibility and comparability of the results of their use.
The use of special methods of diagnostic examination does not replace the diagnostic activity of a doctor. The doctor must know the possibilities of the method and avoid conclusions that are inadequate to these possibilities. For example, according to ECG changes without taking into account the clinic, such a conclusion as “decrease in blood flow in the myocardium” is illegal, because the blood flow and blood supply to the myocardium cannot be measured electrocardiographically. The existing variety and further development of special diagnostic methods suggest the improvement of the diagnostic process only in connection with mastering its methodological foundations and subject to a corresponding increase in the professional qualifications of doctors.
The methodological foundations of diagnostics are formed on the principles of the general theory of knowledge (epistemology), on the methods of research and thinking common to all sciences. As a scientific method, diagnostics is based on the use of historically established knowledge, observation and experience, comparison, classification of phenomena, disclosure of relationships between them, construction of hypotheses and their testing. At the same time, diagnostics, as a special area of epistemology and an independent section of medical knowledge, has a number of specific features, the main of which is determined by the fact that the object of study is a person with his characteristic special complexity of functions, connections and interaction with the environment. A feature of diagnostics is also its connection with the general theory of pathology, therefore, historically, the development of diagnostics as a form of knowledge was determined mainly by the refraction of general philosophical knowledge in specific issues of the development of medical theory, in ideas about health and disease, about the body, its connection with the environment and the relationship in it. parts and the whole, in understanding the causality and laws of development disease.
In modern medicine, the theory of pathology is based on the principles of determinism, the dialectical unity of the organism and the environment (including its geographical, biological, ecological, social and other characteristics), the historical, evolutionary conditionality of the body's reactions to damage, primarily adaptation reactions.
In methodological terms, diagnostics also has a number of features. Firstly, the complexity of the object of study determines the existence in diagnostics of a variety of research methods, rare for one science, both own and borrowed from almost all sections of physics, chemistry, and biological sciences. This requires multilateral training of physicians and a special systematization of knowledge of the natural sciences, designed specifically for solving various types of diagnostic problems.
Secondly, unlike other sciences, where the object of study is recognized by essential and permanent signs, in medicine, the recognition of a disease is often based on insufficiently expressed low-specific signs, and some of them often refer to the so-called subjective symptoms, which, although they reflect objective processes in the body also depend on the characteristics of the higher nervous activity patient and can be a source of diagnostic errors.
Thirdly, the diagnostic examination should not cause harm to the patient. Therefore, a direct and accurate, but potentially dangerous for the patient, method of diagnostic research is usually replaced in practice by a variety of indirect, less accurate diagnostic methods and techniques. As a result, the role of medical conclusions, the so-called clinical thinking, significantly increases in the diagnostic process.
Finally, the features of the diagnostic process are determined by the limited time and opportunities for examining a patient in conditions requiring urgent treatment. In this regard, the doctor’s diagnostic experience is of great importance, which determines the ability to quickly recognize the leading pathology in a given patient based on the similarity of a set of features with a previously observed doctor and therefore has a syndromic or even nosological specificity for the doctor, which, however, is not amenable to abstract description. It is in this sense that we can talk about the role of the so-called medical intuition in the diagnosis.
The process of establishing a diagnosis of a disease during the initial examination of a patient includes analysis, systematization, and then generalization of the symptoms of the disease in the form of a nosological or syndromic diagnosis or in the form of constructing a diagnostic algorithm.
The definition of the disease as a nosological unit is the most important and responsible stage of diagnosis. Nosological approach Provides for the establishment of a diagnosis depending on the coincidence of the entire picture of the disease with known clinical manifestations typical of a certain nosological form (specific symptom complex), or on the basis of the presence of a symptom pathognomonic for it.
Syndromic diagnosis can be an important step towards the diagnosis of the disease. But the same syndrome can be formed when various diseases under the influence of various causes, which characterizes the syndromes as a reflection of a certain pathogenetic essence, as a result of a limited number of typical body reactions to damage. In this regard, the syndromic diagnosis has the advantage that, being established with the smallest amount of diagnostic studies, it is at the same time sufficient to justify pathogenetic therapy or surgical intervention.
A diagnostic algorithm is a prescription for a sequence of elementary operations and actions to establish a diagnosis of any of the diseases manifested by a given set of symptoms or a given syndrome. Diagnostic algorithm). In its perfect form, a diagnostic algorithm is compiled for cybernetic diagnostic methods that involve the use of computers (see. Cybernetics in medicine). However, explicitly or implicitly, the process of medical diagnostics is almost always algorithmized, because the path to a reliable diagnosis, even in the presence of highly specific (but not pathognomonic) symptoms, goes through an intermediate probable diagnosis, i.e. building a diagnostic hypothesis, and then checking it with the data of a targeted additional examination of the patient. In the process of diagnosis, the number of hypotheses should be kept to a minimum (the principle of "economy of hypotheses") in an effort to explain with one hypothesis as best as possible. large quantity available facts (symptoms).
With the primary detection of only non-specific symptoms, diagnostic assumptions in the nosological sense are impossible. At this stage, the diagnostic process consists in a general determination of the nature of the pathology, for example, whether there is an infectious disease or a metabolic disease, an inflammatory process or a neoplasm, an allergy or an endocrine pathology, etc. After that, a purposeful diagnostic additional examination of the patient is prescribed to identify more specific signs or syndrome.
The construction of a diagnostic hypothesis on the basis of symptoms is carried out by inductive reasoning, i.e. from knowledge of a lesser degree of generality (individual symptoms) to knowledge of a greater degree of generality (form of the disease). Hypothesis testing is carried out through deductive reasoning, i.e. from the generalization made back to the facts - to the symptoms and results of the examination undertaken to test the hypothesis. The deduction method makes it possible to detect previously unnoticed symptoms of the disease, to foresee the appearance of new symptoms in the course of the disease, as well as its development itself, i.e. determine the prognosis of the disease. Thus, in the process of diagnosis, inductive and deductive methods necessarily complement each other.
Establishing a syndrome or a relatively specific set of symptoms is usually sufficient to construct several diagnostic hypotheses, each of which is tested in the process of differential diagnosis.
differential diagnostics is based on the detection of differences between the manifestations of a given disease and the abstract clinical picture of each of the diseases in which the same or similar signs are possible. For differentiation, as many symptoms of each disease as possible are used, which increases the reliability of the conclusions. The exclusion of suspected disease is based on one of three principles of differentiation. The first of these is the so-called principle of significant difference, according to which the observed case does not belong to the compared disease, because. does not contain a consistent feature of the disease (eg, the absence of proteinuria rules out nephritis) or contains a symptom that never occurs with it.
The second principle is exception through opposition: the given case is not a supposed illness, because with it, a symptom is constantly encountered that is directly opposite to the observed one, for example, with achilia, duodenal ulcer is rejected, tk. it is characterized by gastric hypersecretion.
The third principle is to exclude the alleged disease on the basis of differences in symptoms of the same order in terms of quality, intensity, and features of manifestations (principle of non-coincidence of signs). All these principles have no absolute value, since The severity of certain symptoms is influenced by many factors, including the presence of concomitant diseases. Therefore, differential diagnosis involves additional verification of the diagnostic hypothesis, even if it seems to be the most reasonable of all hypotheses. The presumptive diagnosis is verified by the practice of subsequent therapeutic and diagnostic measures arising from it, as well as monitoring the dynamics of the disease.
The conclusion of the diagnostic process is the transition from the abstract-formal diagnosis of the disease to a specific diagnosis (diagnosis of the patient), which in its entirety represents the totality of anatomical, functional, etiological, pathogenetic, symptomatic, constitutional and social recognition, i.e. synthesis - the establishment of the unity of the various aspects of the condition of a given patient, his individuality. The diagnosis of the patient does not have generally accepted formulations; in medical documents, a significant part of its content is reflected in the epicrisis. The diagnosis of the patient serves as a rationale for the individualization of treatment and preventive measures.

The ideal model of the process of cognition is its movement along the steps from sensation, perception and representation to the concept, judgment and inference, on the one hand, and from the empirical to the theoretical, on the other. The patterns of the real epistemological process of cognition are, of course, much more complicated.
In reality, in the process of cognition, empirical knowledge begins to form not from some observations, which are fixed in words and expressions in the form of so-called perceptual sentences. For example, diagnostic thinking, although it begins at first glance with observation, is not a cognitive process independent of research for two reasons. First, it is prerequisite. It would be an oversimplification to think that exploratory analysis begins with the fixation of some set of facts or processes. The latter, thanks to the logic of the cognitive process, are “introduced” into a conceptually defined, historically conditioned logical-semantic scheme, which gives the elements of objective reality the status of a scientific fact. Secondly, it is a kind of inferential knowledge penetrating "beyond" concepts, measurement data, actions and actions of individuals.
Diagnostics as a process of cognition contains at least a research setting for choosing the most important signs and sifting out secondary ones already when they are summed up under a symptom.
In the medical sciences, knowledge is substantiated, perhaps to a greater extent than in any other science, on the epistemological attitude of comprehending the truth, the accuracy of knowledge, and at the same time on the normative-value attitudes of society. The ideals of value here have a complex, complex character: on the one hand, there are purely cognitive processes (and, accordingly, criteria of scientific character that are predominantly natural sciences), and on the other hand, normative-value reflective processes (which have a predominantly socio-humanitarian ideal of scientific character). Undoubtedly, for medical workers, orientations towards objective truth act as primary in relation to normative-value reflective processes.
Well-established methodological and methodological principles for the organization of medical knowledge (empirical and theoretical levels, epistemological, normative and value character, etc.) are an important indicator of the scientific nature of their foundations. Knowledge of these grounds is especially important in connection with the versatility and historicity of the object of this field of human science, as well as with the expansion of the range of means of influencing a person, population and social group for the purpose of prevention or treatment. Consequently, the measure of substantiation of the scientific nature of medical knowledge is directly related to the level of development of society, to the reflective capabilities of the subject, and to the specific historical nature of the object and subject of medicine as a science. At the conceptual level, such foundations of knowledge as the scientific picture of the world, ideals and norms of cognition, various philosophical and methodological principles are essential. General premises, foundations and in medicine can be considered with an emphasis on epistemological preference, and not on evidence-based rationale.
Diagnostics as a specific cognitive process remains closely connected with the “human factor” in the era of high technologies, an activity in which the personal aspect of knowledge remains very significant. With some degree of conditionality, it can be argued that the task of any diagnostic study includes an accurate explanation of the established facts. The way to achieve this is the use of the logical apparatus, the language of medicine, understanding and interpretation, and other techniques and methods of cognition.
Diagnostics as a reflective process reveals the syncretism of rationality and empiricism, structural modeling and functional analysis, meaning and meaning. In it, the epistemological and value aspects of reflection are not internal and external, but a single fabric of the creative process.
With the development of theoretical knowledge and the growth of computer processing of information, more attention has been paid to the accuracy and unambiguity of knowledge in medicine. This is due to the fact that accuracy is one of the foundations of the truth of knowledge. Usually it acts as a problem of logical-mathematical and semantic accuracy. Accuracy has a concrete historical character. Usually, formal and substantive accuracy are distinguished. The latter acquired particular importance in connection with the development of metatheoretical research and with the shift of the center of methodological research from direct analysis of the object and ways of approaching experimental knowledge to it, to the study of knowledge itself (logical structure, problems of foundations and translation of knowledge, etc.), to the analysis of language medical science.
The physician inevitably goes beyond the "clinic". This is inevitable, since “pragmatics” and “semantics” are woven into its fabric in the form of a problem of “meaning” and accuracy of knowledge, because the logic of diagnosis and clinic is not formal, but meaningful. Diagnosis as the recognition of a disease in semiotic terms is the process of designating a disease based on the knowledge of its symptoms in a patient. Diagnosis is the summing up of the identified symptom complex under a certain nosological unit.
The ultimate goal of knowledge is truth. True knowledge is the disclosure of the objective laws of reality. Absolute knowledge about an object is an epistemological ideal. Usually, in the process of cognition, one obtains knowledge that, for one reason or another, is an objective and at the same time relative truth. In general, truth is the process and result of cognition, the movement from relative to absolute truth.
In assessing the process of cognition, the correctness of the diagnosis, a key role belongs to practice, which is the starting point, the ultimate goal and the criterion for the truth of knowledge.

To the question whether the world around us is cognizable, answers epistemology (gnosis - knowledge, logos - word). This is the most important branch of philosophical knowledge. She is associated with ontology - the doctrine of the essence of being, and logic - the science of thought. The vast majority of philosophers to the question - "can we know the world?" - answer in the affirmative. Such philosophers are called Gnostics. However, there is also such a doctrine as agnosticism, whose representatives completely or partially deny the fundamental possibility of knowing the objective world. The most famous agnostics were the English philosopher D. Hume and the German philosopher I. Kant. Agnosticism does not deny the very fact of knowledge. He doubts the possibilities of human knowledge.
Many philosophers are quite optimistic about the possibilities of human knowledge. Such concepts include Hegelian(idealistic) and Marxist(materialistic). In certain periods of history, remarkable scientific discoveries were made. In another case, generally accepted ideas about the world, which seemed reliable, collapsed, showing their inconsistency.
There is another direction - skepticism- a direction that exposes everything to doubt and mistrust. Its founder was Pyrrho. Since everything flows and changes, nothing can be said at all and one should refrain from any judgments. The world is so changeable that it is impossible to transfer your knowledge to someone else. The difference between skepticism and agnosticism is that the agnostic does not deny the possibility of theoretical knowledge and judgment, but answers the question: “I don’t know.” Skepticism, on the other hand, can be seen as a method that raises objections to what is accepted and established.
These are the main approaches to the problem of knowledge.
Epistemology claims that the process of cognition is a reflection of reality in the human mind. The object of knowledge is the surrounding reality, the subject of knowledge is a person. The history of knowledge shows that the purpose of knowledge is to obtain knowledge.
Knowledge - it is the highest level of information recognized in a given society.
All knowledge is information, but not all information is knowledge. Information becomes knowledge when a person passes it, as it were, “through himself”. For example, you give a patient a diagnosis. For him, it's just information. But when you explain what caused the disease, how to treat it, what the patient should do, information gradually becomes knowledge. Highest level knowledge of a given society - scientific knowledge, i.e. confirmed by facts, evidence, practice.
There are different forms and levels of knowledge. The first levels of knowledge are sensory and logical. The first is given to us by the senses, the second - by the mind.
The knowledge received by the senses arises through sensations, perceptions, ideas.
Feeling- this is a reflection in the mind of individual aspects or properties of an object (for example, “sweet”, “bright”, etc.).
Perception- reflection in the mind of an object in the aggregate of all its properties (for example, a sweet, red, round apple).
Representation - a reflection in the mind of an object that previously affected the senses (for example, imagine a seashore).
The main forms of the rational level of knowledge are the concept, judgment, conclusion.
concept- highlighting the main features in the subject (for example, a “table” without specifying which one is round, square, dining, writing, etc.).
Judgment- assertion or denial of something. This patient has no signs of peptic ulcer, he has gastritis.
inference is to draw conclusions from given judgments.
For example:
1. Analgin is a non-narcotic analgesic.
2. Non-narcotic analgesics are used for headaches.
3. Therefore, analgin can be used for headaches (if there are no contraindications).
The highest forms of logical thinking are scientific theory and hypothesis.
Hypothesis- assumption about phenomena, events, laws.
scientific theory- proven by facts, practice knowledge about the world around.
In the history of cognition, there is a dispute between rationalists and sensualists about which type of cognition is the most reliable, ensuring the reliability of the truth. The most prominent representatives of these species were, respectively, Descartes and Locke. Sensualists argued that only the sense organs provide true knowledge about the world, and concepts are the fruit of fantasy (fiction) of the human mind. Rationalists argued that the senses and experience do not always correctly reflect reality. In modern science, both types of knowledge are combined. Although sensations and perceptions are the source of all human knowledge, knowledge is not limited to them. From sensory knowledge, from the establishment of facts, the path of knowledge leads to logical thinking.
In addition to logical and sensory, there are other types of cognition. First of all, ordinary and scientific. Ordinary (everyday) is based primarily on observation and ingenuity, consistent with life experience. He should not be underestimated. Common sense is sometimes subtler and more penetrating than the mind of another scientist. It (common sense) is the basis for the daily behavior of people, their relationship between themselves and nature. As a rule, everyday knowledge comes down to stating facts and describing them.
Scientific knowledge is born in a slave-owning society. The impetus in development is received in the period of the 17th-18th centuries, i.e. scientific and technological revolution. Science received special development in the 20th century. This period is called breaking the habitual knowledge about the world and rethinking it. Traditional priorities collapsed. New ones took their place.
How is scientific knowledge different from conventional knowledge? Scientific knowledge presupposes both the explanation of facts and their comprehension in the entire system of concepts of a given science. Scientific knowledge proves how and why this or that phenomenon occurs. A scientific statement becomes only when it is justified. The process of scientific knowledge is inherently creative. The laws of nature, society and human existence are not just imprinted in our minds, they are subject to research, discovery and comprehension. This cognitive process includes intuition, conjecture, fiction, and common sense. In scientific knowledge, reality is clothed in the form of abstract concepts and categories, laws, principles.
But for all the difference between worldly and scientific knowledge, they have a common goal - the idea of orientation in the world. Both types of knowledge are oriented towards recognition, those. comparison with something already familiar.
Art lies on a different plane compared to science. Artistic knowledge has a certain specificity, the essence of which is in the integrity, and not in the dismemberment of the reflection of the world and especially man in the world. A work of art is built on an image, not on a concept: a thought is clothed in “living faces” and perceived in the form of visible events. Art expresses phenomena that cannot be understood in any other way. Another distinctive moment of artistic knowledge is artistic originality, artistic fiction, the possibility of something that does not exist in reality.
But fiction is about the form of expression. Artistic truth should not allow arbitrariness and subjectivism. In the process of cognition, the question of the relationship between knowledge and faith has always arisen. I. Kant believes that there are three types of faith.
pragmatic- a person's belief in his rightness in a given case. Her price is low.
moral faith- here the question of the truth of judgments does not arise at all. These are moral principles. Kant identified it with religious faith. The truth of religious knowledge is not based on external criteria. This is a connection inherent in a person with the existing truth, with the destruction of this truth, one's own Self perishes.
It is known that man himself is the creator, the subject of history, he himself creates the prerequisites for his historical existence. In social cognition, a person deals with the results of his practical activity.
We interact with the world to satisfy our material and spiritual needs. Astronomy was brought to life by the need for navigation; the needs of agriculture gave rise to geometry, and so on.
Practice- this is the sensual-objective activity of people, their impact on a particular object in order to transform to meet their needs. In relation to knowledge, practice plays a threefold role. Firstly, it is a source of knowledge, its driving force, it provides knowledge with the necessary practical material.
Secondly, practice is the sphere of application of knowledge, it is the goal of knowledge.
Thirdly, practice serves as a criterion, a measure of verification of the truth of the results of cognition.
Man does not comprehend reality alone. The experience of one person is not enough to reach the truth.
Science is like an iceberg: the visible part of it is smaller than the part that is hidden under water.
IN scientific research there are different levels. At each given level of development of society, practice is forced to be content with a given level of development of theory, no matter how poor the latter may be.
The purpose of the cognitive process is the comprehension of truth.
True- this is adequate information about the object and characterized in terms of its reliability.
Truth exists outside and independently of our consciousness. True knowledge enables people to rationally organize their practical actions.
Experience shows that a person rarely reaches the truth except through error, which he takes for the truth. Goethe wrote: "He who seeks is compelled to wander." In scientific knowledge, delusions act as false theories, the inaccuracy of which is revealed in the course of the further development of science (for example, the geocentric theory of Ptolemy). These theories should be distinguished from lies as a moral and psychological phenomenon. Such lies are intended to deceive someone. Scientific knowledge, in fact, is impossible without a collision of different, sometimes opposing views.
Each stage of scientific knowledge is limited by the level of development of science, practice, cognitive abilities of a given scientist, specific historical circumstances.
Scientific knowledge, including reliable, is relative. The relativity of knowledge lies in the incompleteness and probability, i.e. truth reflects the object not completely, not entirely, but within certain limits, which are constantly changing and developing.
Relative truth- this is limitedly true knowledge about something.
Each subsequent theory, in comparison with the previous one, is a more complete and profound knowledge. The old theory is interpreted in the composition new theory as relative truth, and thus as special case more complete and new theory.
absolute truth is complete knowledge.
In every relative truth there are certain and absolutely true facts. As scientific knowledge develops, specific gravity absolute is constantly increasing. The development of any truth is the building up of moments of the absolute.
To obtain reliable knowledge, a person uses various methods and techniques.
Method is a system of principles of cognitive, practical, theoretical activity.
The method is specified in the methodology.
Methodology These are specific methods, means of obtaining and processing factual material.
The choice and application of various methods follow from the nature of the phenomenon under study, and from the tasks that the researcher sets himself. Each method makes it possible to cognize only some separate aspects of the object.
The main methods of thinking are analysis and synthesis.
Analysis- mental decomposition of the subject into its component parts. When the particulars have been sufficiently studied by analysis, synthesis sets in.
Synthesis- mental unification into a single whole of objects dissected by analysis. Analysis fixes mainly what distinguishes the parts of an object from each other. Synthesis reveals the main common features that bind the parts into a single whole. Analysis and synthesis are inseparable from each other.
Comparison- Establishing differences and similarities of objects. This method acts as a comparative-historical one. This method originated in philology, and is now used in other parts of knowledge. It allows you to identify the genetic relationship of certain animals, peoples, religious beliefs, patterns of development of social processes, etc.
Induction- the process of deriving a general position from a number of single facts (diagnosis).
Deduction- the process of reasoning, going from the general to the particular (treatment prescription).
abstraction- this is a mental selection of an object in its abstraction from connections with other objects. It is a necessary condition for the emergence and development of any science and human thinking in general.
It has its limit: it is impossible, as they say, to abstract the flame of a fire from what is burning with impunity. As a result of abstraction, various concepts of objects appear ("human", "animal", "patient", "illness", "health").
Analogy- this is a plausible probable conclusion about the similarity of two objects in any sign on the basis of their established similarity in other signs. In this case, the conclusion will be the more plausible, the more similar features the compared objects have and the more significant these features are. These are only probable conclusions, they are the basis of the imagination and lead to the formation of hypotheses.
The role of modeling is growing in modern scientific knowledge. Modeling- this is the creation of a natural or artificial analogue of the object or phenomenon being studied.
Model- this is an imitation of an object or its properties with the help of other objects or phenomena. Modeling is becoming widespread because it makes it possible to study the processes characteristic of the original, in the absence of the original itself.
Imagination and intuition play a special role in the process of cognition. ancient greek philosophers called intuition inner vision.
Intuition- this is the ability to comprehend the truth by its direct discretion without substantiation with the help of evidence.
An experienced doctor can immediately, without reasoning, understand the essence of the disease, and then justifies the correctness of his instinct. Intuition is a kind of insight. It is impossible to teach a person to intuition. But intuition is not something super-rational or unreasonable; thinking, feeling, sensation are closely connected in it. It brings science closer to artistic creativity. Creative imagination, fantasy are the necessary means of developing a person's ability to change, transform the world.
The laws of fantasy are different from the laws of logic. Creative imagination allows us to capture the meaning of the new and see the paths leading to it by barely noticeable details. A person who does not have a creative imagination cannot see anything special in the abundance of facts, he is used to them. A.G. Spirkin believes: “The habit in scientific thinking is the crutches on which, as a rule, everything old rests.” Creative imagination is nurtured throughout the course of life. Art is essential in his upbringing, it develops imagination and gives room for creative ingenuity.
But fantasy and intuition are enough to discern the truth, but not enough to convince others and oneself of this truth. This requires proof.
Evidence- the vital condition of scientific thinking.
The proof is built on the principle: the thesis, the grounds for proof (arguments) and the method of proof.
Thesis- a proposition, the truth or falsity of which is clarified by means of evidence.
The evidence by which the falsity of the thesis is clarified is called rebuttal.
Arguments proving the truth of the thesis consist of reliable facts, definitions, axioms and previously proven provisions. In the course of the proof, as a rule, not one, but a combination of methods is used.
The specifics of medical knowledge
Diagnostic observation methods include medical observation and examination of the patient, as well as the development and application of special methods for studying morphological, biochemical and functional changes associated with the disease. Historically, the earliest diagnostic methods include the main methods of medical research - anamnesis, examination, palpation, percussion, auscultation.
There are 3 types of examination of the patient: a) questioning, b) examination, percussion, palpation, auscultation, that is, direct sensory examination, and c) laboratory and instrumental examination. All three types of examination are both subjective and objective, but the most subjective method of questioning. Conducting a study of the patient, the doctor must be guided by a certain system and strictly adhere to it.
Unfortunately, the doctor sometimes sees separately the liver, stomach, nose, eyes, heart, kidneys, bad mood, suspiciousness, depression, insomnia, etc. But it is necessary to cover the patient as a whole, to create an idea of the personality! However, some doctors do not even want to hear about it. Although doctors have long known that the condition nervous system affects the course of somatic processes. M. Ya-Mudrov noted: "... the sick, suffering and despairing, thereby take their own lives, and die from the mere fear of death." (Selected prod. M., 1949, p. 107). The French surgeon Larrey claimed that the wounds of the winners heal faster than those of the vanquished. Any somatic disturbance leads to a change in the psyche and vice versa - the changed psyche has an impact on somatic processes. A clinician should always be interested in the mental world of a person, his attitude to people, society, nature; the doctor is obliged to find out everything that forms a person and affects him.
According to the ancient scientists of Greece, the greatest mistake in the treatment of diseases was that there are doctors for the body and doctors for the soul, while both are inseparable, “but this is precisely what the Greek doctors do not notice, and that is the only reason why they so many diseases are hidden, they do not see the whole ”(quoted by V. Kh. Vasilenko, 1985, p. 49). Plato argued: “The greatest mistake of our days is that doctors separate the soul from the body” (quoted by F.V. Bassin, 1968, p. 100).
The French clinician Trousseau recommended always carefully watching patients, remembering the image of the disease - this is the priceless wealth of the doctor. When diagnosed, Similarly they always begin to remember the images of the sick and illnesses they saw. A diagnostician needs experience, a lot of experience, and the sooner he gains it, the sooner he will succeed. Clinical medicine, especially diagnostics, is not at all an area in which you can succeed if you "push".
The doctor comes to the diagnosis and prognosis not only thanks to the knowledge of the laws of the course of pathological processes, but also through the accumulation own experience allowing to apply this knowledge in specific conditions. However, the great value of medical experience by no means frees the doctor from the need to replenish and improve his theoretical knowledge, observe strict methodology in examining patients and not pass off a poorly proven and insufficiently substantiated diagnostic guess as the truth, referring only to his own experience. Clinical experience makes it possible to typify diseases, to discover the patterns of their course, but it does not always make it possible to comprehend the essence of the disease, its pathogenesis. Therefore, overestimation, as well as underestimation of experience, are unacceptable. However, we are constantly surprised and delighted by the ability of some doctors, thanks to their rich and "smart" experience, to make the correct diagnosis almost instantly at first glance, to recognize many of the patient's personality traits.
Not everything human can be represented in the form of numerical expressions. It would be a mistake to reduce the human world to mathematical formulas. A. Einstein claimed
that the work of Dostoevsky gave him, as a scientist, more than the works of the greatest mathematicians in the world?!
Nature is one, but mathematics is by no means its only language, especially if you need to embrace and understand the phenomenon as a whole, in the form of an integral system, and man belongs to such. A modern computer, endowed with a phenomenal ability to fantastically quickly perform two arithmetic operations, is completely indifferent to a person's personality, his inner world, and emotional mood. For diagnostics, a doctor needs not only accurate, but also a lot of “inaccurate” knowledge, which allows him to find a way to the soul, to the consciousness of a sick person. The primary information about the patient, the symptomatology of the disease is revealed by a human doctor, not by a machine! We should not, we have no right to thoughtlessly, boundlessly trust technology, no matter how perfect it may be. The tragic experience of Chernobyl teaches us this. The technique should be extremely “fullproof”, that is, “foolproof”, and people should be extremely conscientious in handling it. Mathematical meanings in clinical medicine should be accepted, but they should not be exaggerated, fetishized. A. F. Bilibin, G. I. Tsaregorodtsev (1973) notice that sometimes falling under the hypnotic influence of the exact sciences, doctors begin to believe that clinical processes are governed by the same laws as in other areas of knowledge. However, such an understanding is tantamount to denying the specificity of clinical thinking. A good clinician is first of all a kind and soulful person and a great psychologist! And the more perfect the devices, the more accurate and perfect the medical technique, the smarter and more educated the clinician must be, the more creative analysis and imagination is required from the doctor. Diagnosis is a creative act of a doctor, and not the result of a computer, which itself is a product of human thinking, and not vice versa! Technique and man should harmoniously complement each other, the benefits of industrialization should be used to the maximum, and at the same time, personal psychological contact between the patient and the doctor should be fully protected. In the work of a clinician, there is a lot of not only rational, but also emotional activity, the doctor uses not only formal knowledge, but also experience, they should not be opposed to each other. The father of cybernetics, Norbert Wiener, pointed out: “Man gives cybernetic machines the ability to create and creates for himself a powerful helper. But it is precisely here that the danger lurks, which may arise in the very near future.” One of the first reports of an epidemic that struck personal computers hundreds of thousands of Americans came from the USA. It turned out that the "virus" was brought from the Pakistani city of Lahore, from a small computer software store, whose owners deliberately sold game programs corrupted by the "virus", which made something similar to electronic confetti from computer memory. More and more new cases continue to be reported in various countries the world of voluntary or involuntary disruption of computers, due to the fact that their memory is clogged with meaningless alien programs. In the modern world, the development of computer ethics is still far behind the rapid growth of computer literacy.
In clinical medicine, we must use the achievements of physics, mathematics, chemistry, technology and other sciences, but we should always remember that the patient is not only an object, but also a subject, and we must pay more attention to the personality of a person. With the help of logic, if not everything, then a lot can be proved, but the truth is not only what can be proved to a doctor. Sometimes, based on experience, one even has to come into conflict with modern supposedly scientific provisions, to oppose the results of formal-logical thinking to empirical laws developed by practice, but not yet realized by science. Living nature does not fit once and for all into definitive (definite) formulas. The most perfect algorithm will not replace communication with the living, contradictory soul of a person. We sometimes strive to shortchange even those data that do not need it. A kind of fashion for quantitative definitions has appeared, but fashion is seriality, and seriality is a step towards dullness.
The strength of a doctor is not only in logic and in the ability to obtain quantitative expressions of certain parameters used in practical medicine, but also in his ability to operate with qualitative categories, without which it is impossible to understand the personality of the patient, and this is achieved by personal contact with the patient, comes with experience. The statement of A. de Saint-Exupery about the importance of personal contact between the patient and the doctor has already gained textbook fame: “I believe that the day will come when the patient, who knows what, will give himself into the hands of physicists. Without asking him anything, these physicists will take blood from him, derive some constants, and multiply one by the other. Then, after consulting a table of logarithms, they would cure him with a single pill. And yet, if I get sick, I will turn to some old zemstvo doctor. He will look at me out of the corner of his eye, feel my pulse and stomach, listen. Then he coughs, lighting his pipe, rubs his chin and smiles at me to better ease the pain. Of course, I admire science, but I also admire wisdom” (quoted by M. Mizho, 1963, p. 273).
Even the ancients used to say “Eggage humanum est” (“it is human nature to err”), but, perhaps, in no other area of human activity, errors entail such frequent and severe consequences as in the field of clinical medicine, including diagnostics. There is a large literature devoted to errors in diagnosis. The level of medicine is changing, the training of doctors is improving, new methods of examination are being introduced into practice, the nature of errors is changing, but the problem of diagnostic errors itself remains. Especially a lot of medical errors are generated by untimely, belated diagnosis, so the desire for an early and correct diagnosis remains always relevant, since an early diagnosis allows timely and early adequate treatment of the patient. A distinction must be made between diagnostic and medical error- the latter has a broader concept, since it includes both a diagnostic error and errors associated with the prediction and treatment of diseases. The only criterion of reliability, the ability to distinguish between essential features from non-essential ones, true judgments from false ones, is the practice, practical activity of a doctor.
To check the quality of diagnostics and identify diagnostic errors, there are two methods: a) studying the degree of coincidence of the diagnoses of some medical institutions (polyclinics) with the diagnoses of other institutions (hospitals); this is an indirect verification of the validity of the diagnosis; b) the study of the degree of coincidence of clinical and pathoanatomical diagnoses, this is a direct verification of the truth of the diagnosis.
M. Ya. Mudrov: “ medical science, therapy teaches a thorough treatment of the disease itself, medical art, practice and clinic teaches the treatment of the patient himself ”(1949, p. 21) S. P. Botkin (1950, v. 2, p. 14-15) for the first time formulated the physiological, functional direction in the clinic and sought to introduce scientific methods into practical medicine as widely and deeply as possible. He believed that clinical medicine is first and foremost a science. He owns the following statement: “To treat the patient, to alleviate his suffering and, finally, to prevent the disease, requires knowledge and art to apply it at the present time. This is an art belonging to the individual, and was so high in antiquity that man associated it with the concept of a deity; with the passage of history, art has been lost along with individuals, except for solid scientific foundations.
The existing knowledge of certain facts not subsumed under general truths did not constitute science. Modern classification countries by main areas of economic activity defines three categories: trading in resources, industrial and producing a landmark intellectual product. The well-known sociologist E. Toffler refers the latter group to the countries of the so-called "third wave", which is due to the rapid development of information technology. How does this digression relate to the topic of this study? Economic priorities directly determine dominant morals in each of these categories of countries. In the book of well-known Ukrainian scientists on the methodology of biomedical science, it is noted that the ways of obtaining knowledge, the choice of a working hypothesis and other approaches in the study "... are determined by the priorities accepted in society, understanding the meaning of scientific knowledge" (Ternovoy K.S., 1990 [p. 16] ).
The shift of priorities in Ukraine to the area of trade in the country's strategic resources and the promotion of foreign goods, rather than the production of a new iconic product, determines the modern model of our corrupt country and forms the corresponding morals and sciences. In conditions when a country pays the work of a scientist worse than a private firm pays the work of a clerk or a skilled worker, the meaning of scientific knowledge is simplified to a simple description of disparate facts with an indefinite level of probability.
You can talk a lot about the problems of the mores of society, but real changes will not occur from these conversations. At the first stage of the reform, it is necessary to clearly formalize for all members of the community the conflict between declarations and mores. The people received dosed information stereotypes that allowed them to manipulate public opinion in favor of the authorities. E. Toffler perfectly showed in his books (Toffler E., 2004a) that in today's society the power of the state is provided by the bureaucracy, whose task is to manage the flow of information so that in society there is an illusion of full compliance of laws and real public relations.
In the book “Metamorphoses of Power”, E. Toffler shows that at the present time in developed countries, the bureaucracy is losing ground from under its feet due to the development of the Internet (Toffler E., 2004b). Alternative flows of information have become beyond any control and restrictions on the part of the state. E. Toffler's models are very convincing. For example, the “Power of Minorities” model shows that in a society where there is freedom of information flows, a certain cohort of citizens can always organize themselves and very quickly bring the mores of a certain cohort into line with its declarations.
This model is fully consistent with the rapidly developing movement of professional associations in medicine.

Introduction
Philosophy and medicine are cultural phenomena equally ancient in their origin; their close relationship is manifested in the proximity of the subjects of study (the study of a person, his personality and the influence of society on a person), the similarity of goals and objectives, the unity of methodology, and value orientation. Despite different areas of activity and different ways of searching for truth (medicine chooses the path of practical action at the dawn of its existence, philosophy - the path of theoretical generalization and reflection), both of them solve the same problem - the problem of the survival of mankind on Earth, the problem of self-determination of man as a natural and cultural being. In this matter, philosophy and medicine cannot help but unite their efforts, since separately they are deprived of integrity - philosophy moves away from empiricism, “hovers in the clouds”, while medicine, plunging into the study of the body, forgets about the individual, “drowns” in details and particulars.
Throughout its long history of development, medicine has gone hand in hand with philosophy. “A doctor who is also a philosopher is like a god,” said Hippocrates. “A genuine and real natural philosophy is needed, on which the whole edifice of medical science must be built,” wrote Francis Bacon.
The problem of knowledge is one of the most important in philosophy and medicine. Cognition is the process of acquiring and developing knowledge, conditioned, first of all, by socio-historical practice, its constant deepening, expansion and improvement.
Cognition and its study is not something immutable, given once and for all, but is "something dialectical" that develops according to certain laws.
In the work of any doctor, the most difficult section is diagnostics - a section of clinical medicine, including the content, methods and means of recognizing diseases and the patient's condition in order to take appropriate therapeutic and preventive measures. The object of knowledge in clinical medicine is a person, but the patient is not only an object, but also a subject of knowledge, therefore, in diagnostics, objective and subjective are closely intertwined, and this combination is more complex than in any other field of knowledge.
Modern medicine at the turn of the XX-XXI centuries. has achieved tremendous success: suffice it to note the impressive achievements in the field of cardiac surgery, transplantology, medical technology, the prevention and treatment of many infectious diseases, as well as in the field of fundamental medicine. Preservation and improvement of people's health by improving the diagnostic process, the introduction of new treatment technologies are the most relevant in the development of modern medicine.
The purpose of this work is to study the problems of diagnosing human diseases as a specific process of cognition that exists throughout the development of philosophical thought.
In connection with this goal, the following research objectives can be formulated:
what is the philosophy of medicine and its historical development;
determine the essence of the cognitive process;
- identify features modern interaction of philosophy and medicine ;
To reveal the features of the philosophical problem of diagnostics as a specific cognitive process.
The abstract consists of an introduction, four chapters, a conclusion and a list of references.
Philosophy of medicine and its historical development
Throughout the history of culture, the ideas of combining philosophical and medical knowledge in order to comprehend the secrets of life and the secrets of man have been implemented in the works of the most famous philosophers, physicians, naturalists. As a result, a special branch of knowledge has developed - the philosophy of medicine, which is designed to generalize the available practical knowledge about a person as a biological and social, material and spiritual being and find adequate ways to adapt a person to the surrounding conditions of life.
The symbiosis of philosophical and medical ideas is ancient Eastern wisdom contained in the Egyptian book of the dead, the Indian Vedas, in the teachings of Chinese Taoists (the doctrine of immortality), as well as in the writings of physicians - philosophers of the East (for example, Avicenna). The basis of the Eastern philosophy of medicine has always been the principle of consistency in the study of the micro- and macrocosm, a feature is the consideration of the human body as a self-sufficient entity in which spirit and body are inextricably linked; diseases of the body are considered here primarily as diseases of the spirit, respectively, the treatment of the disease is, first of all, restoration peace of mind and spiritual health. In Ancient Greece - the cradle of philosophical knowledge - philosophy and medicine also closely cooperate and mutually enrich each other. They are united by the desire to understand the human psyche, an attempt to answer the question of what a person is, what is the (personal and social) value human health whether a person is a biological or social being (these issues are considered in the works of such famous ancient Greek doctors and philosophers as Empedocles, Aristotle, Hippocrates, etc.)
In the medieval European tradition, philosophical and medical studies continue to overlap. A new branch of knowledge is actively developing, located at the intersection of philosophy, medicine and natural science research (primarily chemistry), which also includes elements of divination and witchcraft - alchemy. Despite the unrealistic goals (search for the elixir of life or the philosopher's stone), alchemy played a positive role both in the study of the human being (J. Fracasto) and in the development of certain methods of laboratory technology, especially necessary for developing practical medicine (for example, distillation, sublimation, etc. .). European doctors-philosophers of the Middle Ages (F. Rabelais, R. Bacon, Paracelsus, etc.) anticipated many subsequent medical discoveries and developments, methods of treating diseases; they also studied the impact of society (the social status of the individual) on the development of pathological processes in the body. Overcoming and revising many of the foundations of ancient medicine and human philosophy, medieval scientists and naturalists contributed to the introduction chemicals in medicine, as well as laid the foundations for the theory of human adaptation in the environment.
The ratio of philosophy and medicine in the era of the New Time is dictated by the interest in man, his new interpretations. So, in the philosophy of French materialism (the ideas of the doctors Locke, La Mettrie), a person is understood as a machine acting by analogy with the macrocosm (according to the laws of Newton's classical mechanics). The philosophy of the 19th century comprehends the problems of man as a social being, the problems of the influence of the psyche on the development of pathological processes in the human body. The ideas of the 19th century (Freud, Gestalt psychology, etc.) gave rise to psychosomatic medicine at the beginning of the 20th century<#"justify">The main content of human consciousness is knowledge. Knowledge is the result of cognitive activity. The problem of cognition is recognized as one of the main philosophical problems. Cognition is an activity aimed at obtaining new knowledge. Mankind has always sought to acquire new knowledge. The theory of knowledge explores the nature of human cognition, the forms and patterns of transition from a superficial idea of things (opinions) to comprehension of their essence (true knowledge), and in this regard, considers the question of ways to achieve truth, its criteria.
But a person could not know the true as true if he did not make mistakes, therefore the theory of knowledge also investigates how a person falls into errors and how he overcomes them. Finally, the most burning question for all epistemology has been and remains the question of what practical, vital meaning has reliable knowledge about the world, about man himself and human society. All these numerous questions, as well as those that arise in the field of other sciences and in social practice, contribute to the formation of a vast problematic of the theory of knowledge. The human mind, in the process of cognition, each time tries to answer the question: is the world cognizable, is the person himself and his organism cognizable?
In an attempt to answer it, three main lines can be identified: optimism, skepticism and agnosticism. Optimists affirm the fundamental cognizability of the world, while agnostics, on the contrary, deny it. Skeptics do not deny the fundamental cognizability of the world, but express doubts about the reliability of knowledge.
The main problem that leads to agnosticism is the following: the subject in the process of its cognition is inevitably refracted through the prism of our senses and thinking. We receive information about him only in the form that he acquired as a result of such refraction. And if so, how is it possible for the human mind to comprehend the essence of the universe? It turns out that we are limited in our ways of knowing, and are not able to say anything reliable about the world, about ourselves.
One of the origins of agnosticism is epistemological relativism - the absolutization of the variability, fluidity of phenomena, events of being and cognition. Proponents of relativism proceed from the principle that everything in the world is transient, and what was considered true yesterday is recognized as a delusion today. Value judgments are subject to even greater fluctuation.
The skeptical thought goes back partly to the reasoning of ancient philosophers: "Whoever wants to know clearly, must first doubt thoroughly."
Agnosticism is a hypertrophied form of skepticism. Skepticism, recognizing the fundamental possibility of knowledge, expresses doubt about the reliability of knowledge. A man driven by the desire for knowledge says, "I don't know what it is, but I hope to find out." The agnostic says, "I don't know what it is, and I never will." However, a reasonable degree of skepticism is useful and even necessary, especially in medicine. As a cognitive device, skepticism appears in the form of doubt, and this is the path to truth. Ignorance affirms and denies; knowledge is in doubt. Speaking of cognition, one should pay attention to the extraordinary variety of types or characters of knowledge.
Everyday knowledge and everyday knowledge is based primarily on observation and ingenuity, it is empirical in nature and is better consistent with life experience than with abstract scientific constructions. The importance of worldly knowledge as a precursor to other forms of knowledge should not be underestimated: common sense is often more subtle and insightful than the mind of another scientist.
Scientific knowledge presupposes an explanation of facts, their comprehension in the entire system of concepts of a given science. Scientific knowledge answers the questions not only how, but also why it proceeds in this way. Scientific knowledge does not tolerate lack of evidence: one or another statement becomes scientific only when it is substantiated. The essence of scientific knowledge lies in the understanding of reality, in a reliable generalization of facts, in the fact that behind the random it finds the necessary, regular, behind the individual - the general.
Cognition presupposes the division of the world into an object and a subject. The subject is a complex hierarchy, the foundation of which is the entire social whole. Ultimately, the ultimate producer of knowledge and wisdom is all of humanity. In society, groups of individuals are historically distinguished, special purpose and whose occupation is the production of knowledge of particular vital value. Such, in particular, is scientific knowledge, the subject of which is the community of scientists. In this community, individual individuals stand out, whose abilities, talent and genius determine their especially high cognitive achievements. History preserves the names of these people as a designation of outstanding milestones in the evolution of scientific ideas.
A fragment of being, which is in the focus of cognition, constitutes the object of cognition, becomes in a certain sense the “property” of the subject, having entered into a subject-object relationship with him. In modern epistemology, it is customary to distinguish between the object and the subject of knowledge. By the object of knowledge they mean real fragments of being that are being investigated. The subject of knowledge is the specific aspects to which the point of the searching thought is directed. So, a person is the object of study of many sciences - biology, medicine, psychology, sociology, philosophy, etc. However, each of them “sees” a person from its own point of view: for example, psychology explores the psyche, the spiritual world of a person, his behavior, medicine - his ailments and methods of their treatment, etc.
It is known that a person is a creator, a subject of history, he himself creates the necessary conditions and prerequisites for its historical existence. Consequently, the object of socio-historical knowledge is not only cognized, but also created by people: before becoming an object, it must be preliminarily created and formed by them.
In man's knowledge of the essence of the pathological process in the body, man deals with organisms of his own kind. Being the subject of cognition, it turns out to be at the same time its object. Because of this, the interaction of subject and object in such cognition becomes especially complicated.
Modern interaction of philosophy and medicine
All the basic theories of modern medicine, one way or another, are connected with the philosophy of medicine, which determines the fundamental postulates and positions of general theoretical systems. So, modern philosophical research (philosophical anthropology, philosophy of consciousness, social philosophy) underlies:
the medical theory of adaptive response (the theory of adaptation is a general biological theory of medicine, however, medicine deals not only with biological adaptations, but also with social adaptation, i.e. adaptation of a person to social life),
the theory of determinism (causation and connection of pathological processes occurring in the body),
as well as the theory of normal (optimal) self-regulation and the theory of general pathology.
The so-called “philosophy of healing” becomes the philosophical foundations of clinical medicine, i.e. theory of diagnosis, treatment, rehabilitation, etc., built in accordance with the understanding of the essence of man as a psycho-bio-social being. As a philosophical basis for preventive medicine, one can consider research in the field of the theory of hygiene as an optimal state of a person and the environment. The philosophical theory of values is the philosophical foundation of medical ethics, deontology, and clinical practice.
Modern Philosophy acts as a methodological foundation of medical knowledge, which is designed to unite disparate private studies and systematically apply them to the study of a qualitatively unique living system - a person. The dialectical method comes to the fore in the activity of a modern doctor, since only it provides a comprehensive, systematic approach to the issues of the disease, its treatment, prevention, and rehabilitation period.
The dialectical approach is based on holistic systems thinking, which unites, rather than dismembers, opposites, and also takes into account the relationship between the general and the local (even the ancient doctors noticed that the body is holistic, and if any element (part) is broken in it, then in a certain degree, the whole organism also changes, its vital activity as an integral system is disturbed.).
The task of the philosophy of medicine, of course, does not come down to simply bringing certain provisions of dialectics in connection with medical knowledge, its main goal is to teach students, clinicians to apply dialectics to the analysis of specific natural scientific and clinical factors, and then from knowledge to move to the ability to apply dialectics in practice. A doctor who does not know the dialectical method, no matter how good a specialist he is, will not be able to correctly assess the intersecting and contradictory pathological processes in the body and in best case intuitively be able to come to the right conclusions - correctly diagnose and prescribe treatment.
The dialectical method used today in various fields of knowledge and naturally in modern medicine is based primarily on systems thinking. A systematic approach, which is typical for modern science in general, is especially important in medicine, because she works with an extremely complex living system - a person whose essence is by no means reduced to a simple interaction of organs human body. In fact, the theory of treatment itself is a specific theory of the management of a living system, since treatment is a system of measures aimed at psychosomatic optimization of the human condition.
Delving into the study of complex interrelated systems of the human body, a modern doctor must be guided by the main provisions of the theory of systems developed in the philosophy of natural science since the middle of the nineteenth century. Thus, the philosophy of medicine calls for considering the phenomenon of disease as a structural and functional systemic process. The principles of structurality in medicine are implemented as the principles of the unity of morphology and physiology in the theory of pathology. The biological structure combines a dynamic substrate (an object of morphology) with a “formed” process (an object of physiology). Until now, in medicine, the theoretical recognition of the unity of structure and function coexisted peacefully with the belief that at the onset of a disease, changes in organs and systems do not go beyond the so-called functional disorders. Achievements of modern biology and medicine, especially molecular biology, biophysics, genetics allow us to confidently deny the existence of functional diseases and make it possible to find a morphological substrate that is adequate to any dysfunction. Thus, the system-functional approach in medicine allows both to study the details, parts, processes of an individual organism, to consider the functions of its systems, and not to forget about integrity, studying a person not as a mechanical conglomerate of "parts and details", but a living system, organically inscribed into natural and social reality
Armed with a systemic method, a modern doctor has no right to forget that it is not an organism, but a person, that lies on a clinical bed: the doctor in this case must take into account not only the state of his soma, but also the state of mental, personal and individual characteristics. The same can be said about the problem of making a diagnosis, which includes an analysis of the epistemological problems of diagnosis, an analysis of the subjective and objective causes of diagnostic errors, and taking into account the socio-cultural “underlying reason” of the disease.
In the 20th century, synergetics was created as a complex interdisciplinary direction in science and a method of scientific activity. Synergetics studies open, non-linear, stable systems, a typical example of which is a person. Combining the efforts of synergetics and medicine is one of the important tasks of modern philosophy of medicine. Synergetics opens up new approaches to human health, where treatment takes on the image of discovering oneself. Treatment and cure appear as synergistic processes in which hidden installations for a healthy future.
Using the scientific apparatus of synergetics, it is proposed to study the body as an integral open system, characterized by a special type of interaction of its parts. Obviously, any pathological change in an organ, tissue, etc. serves as a source of perturbation not only of this organ, but also of others, while there is a violation of the usual connections of systems and organs of the human body and the formation of new pathological connections, the development of which is difficult to predict and, accordingly, to predict the forms of progression of the disease.
A characteristic example of the use of the ideas of synergetics in medicine is the study of the processes of interaction of parts of the human body with geocosmic factors. Both geocosmic systems and man are dissipative systems (open, i.e. interacting and exchanging matter and energy with external environment). A complex of geocosmic factors is capable of influencing the system of the human body: the average monthly sums of the correlation of leukograms, electrolyte balance, and the enzymatic status of the blood are synergistic (corresponding, related) with the average monthly dynamics of cosmic rays. Studies have shown that biological systems have the properties of emergency self-organization and dynamic adaptability to changes in environmental factors. The emerging chaos is compensated by the process of self-organization, ordering the system.
Thus, synergetics becomes a way not only of cognition, but also, in a particular case, of understanding and treating a person as a psychosomatic being. Synergetics entails a new dialogue between man and nature, the creation of a new eco-reality. It should be recognized that synergetics is closely related to dialectics and systems theory, largely uses their categorical apparatus, considering the problems of evolution, consistency, interaction, as well as factors of chance, necessity and reality.
Unfortunately, the current state of theoretical medicine (the doctrine of the disease, compensatory-adaptive processes, mechanisms for compensating for impaired functions, connections and relationships of parts in the body, etc.) allows us to state the fact that theoretical medicine today is not yet complex knowledge and is still still presented in the form of separate fragments, but not a complete system. G. Selye in his work “At the level of the whole organism” wrote: “Life is not a simple sum of its constituent parts ... The further you dismember ... living complexes, the further you go from biology and in the end you are left with only majestic, eternal and comprehensive laws inanimate nature... In the knowledge of living nature in general, a contradiction constantly arises - from elementarism to integrity and from the latter again to elementary dismemberment. The thought of researchers inevitably faces a cognitive paradox, noted by Schelling: how to know the whole before the parts, if this involves knowing the parts before the whole ... Scrupulous study of particulars, details, so characteristic of medical science, certainly contributes to the progress of medical knowledge, however, the almost complete absence of generalizations private knowledge of various branches of medicine into a logically and experimentally substantiated theoretical system, the so-called general pathology, hinders the development of modern medicine.
Diagnostics as a specific cognitive process
philosophy medicine disease knowledge
The diagnosis in clinical medicine is a brief conclusion about the essence of the disease and the patient's condition.
Diagnostics consists of three main sections: a) semiology - the study of symptoms; b) methods of diagnostic examination; c) methodological foundations that determine the theory and methods of diagnosis (Postovit V.A., 1991)
Diagnosis is the main, core essence of clinical medicine. The diagnosis must be correct, detailed and early. The diagnosis is based on the nosological principle, which includes the name of a particular disease in accordance with the existing nomenclature. According to the method of constructing and substantiating the diagnosis, two types of it are distinguished - direct and differential. The essence of the first (direct) is that the doctor, having collected all his typical, or pathognomonic, signs, considers them from the point of view of only one alleged disease. The essence of the differential diagnosis lies in the fact that from a number of different diseases that have many common features, after establishing differences, one or another disease is excluded. Differential diagnosis consists in comparing this particular clinical picture with a number of other clinical pictures in order to identify one of them and exclude the rest.
A sign in the diagnosis of diseases can be a “symptom”, “syndrome”, “symptomatic complex”, “clinical picture”. These signs differ in their specificity and degree of generality. A symptom is a single (specific or non-specific) symptom. Symptoms can be divided into overt and covert. The former are detected directly by the doctor's sense organs, the latter - with the help of laboratory and instrumental research methods. A symptom complex is a non-specific combination, a simple sum of symptoms. A syndrome is a specific combination of several internally related symptoms. A specific symptom, a symptom complex, a syndrome are special features. The clinical picture - the totality of symptoms and symptom complexes - is a universal (classic) symptom of the disease. However, the signs of the disease in the classical general view when all the symptoms and symptom complexes are present, rarely occur in reality. Therefore, a universal feature is revealed through single features and their special combinations.
Only in relatively rare cases, when a pathognomonic or highly specific symptom (symptom complex) is detected, is it possible to make a reliable nosological diagnosis. Much more often, the doctor deals with a combination of general, non-specific symptoms in a patient and must expend considerable effort on their analysis. At the same time, in the diagnosis, the symptoms should not be mechanically summed up, but interconnected, taking into account the significance of each of them.
Clinical experience shows that of the three sections of diagnostics, medical logic is the most important, because the constantly evolving semiology and medical technique are of subordinate importance. For example, one of the types of inference is an analogy - about the similarity and difference of symptoms in a particular patient with symptoms of known diseases. More complex methods in the epistemological process are induction and deduction.
Induction is a research method that consists in the movement of thought from studying the particular to formulating general provisions, that is, diagnostic thinking moves from individual symptoms to the establishment of a nosological diagnosis. Deduction is an inference moving from knowledge of a greater generality to knowledge of a lesser degree of generality. The logical structure of a clinical diagnosis is the key way to solve any diagnostic problem with a high degree of efficiency or to get as close as possible to its solution. Even with insufficient erudition in matters related to the related specialty, the doctor, using the logic of clinical thinking, will not pass by an obscure phenomenon, but will try, using the methods of diagnostic logic and attracting the necessary information at each logical stage, to find out the pathological essence of the disease and the degree of its danger to the patient.
The movement of knowledge in the diagnostic process goes through a number of stages, reflecting the analytical and synthetic activity of the doctor. So, according to V.P.Kaznajnaev and A.D.Kuimov, the entire logical structure of making a clinical diagnosis after the direct (empirical) perception of the patient as a specific identity can be divided into 5 stages:
The first stage (the first degree of abstraction): clarification of the anatomical substrate of the disease, that is, its localization in the body.
The second stage (second degree of abstraction): elucidation of the pathoanatomical and pathophysiological nature of the pathological process.
The third stage (the highest degree of abstraction): the formation of a working diagnostic (nosological, rarely syndromic) hypothesis.
The fourth stage: finding out the degree of probability of the diagnostic hypothesis through differential diagnosis.
Fifth stage (synthetic, return from an abstract diagnosis to a specific one): clarification of the etiology and pathogenesis, formulation of a clinical diagnosis taking into account all the features of this disease, drawing up a treatment plan, determining the prognosis of the disease, subsequent verification of the diagnostic hypothesis in the process of examination, observation and treatment of the patient.
In the scheme of the diagnostic process of V.A. Postovit, three phases are distinguished:
Identification of all symptoms of the disease, including negative symptoms, during clinical and laboratory examination. This is the phase of collecting information about the incidence in a particular patient;
Comprehending the detected symptoms, "sorting" them, assessing them according to the degree of importance and specificity, and comparing them with the symptoms of known diseases. This is the phase of analysis and differentiation;
Formulating a diagnosis of a disease based on the identified signs, combining them into a logical whole is the phase of integration and synthesis.
However, the division of the diagnostic process into separate stages is conditional, because in real diagnostics it is impossible to draw a line between the stages of this process, to determine exactly where one ends and the second begins. In the real life diagnostic process is continuous, strictly limited in time and there are no clearly defined periods and a consistent transition of the thought process in it, therefore the doctor classifies the symptoms continuously, during the very examination of the patient.
Clinical thinking is a specific mental conscious and subconscious activity of a doctor, which makes it possible to most effectively use the data of science, logic and experience to solve diagnostic and therapeutic problems in relation to a particular patient. The main forms of clinical thinking are carried out through analysis and synthesis.
There are many guesses in diagnostic activity - the so-called hypotheses, so the doctor must constantly think and reflect, taking into account not only indisputable, but also difficult to explain phenomena. A provisional diagnosis is almost always a more or less probable hypothesis.
According to E.I. Chazov, the success of a doctor's professional diagnostic activity is ultimately determined by the logical and methodological possibilities of his medical thinking.
The need for doctors to know logic is especially growing today, because it becomes obvious that a significant part of diagnostic errors are not so much the result of insufficient medical qualifications, but an almost inevitable consequence of ignorance and violation of the most elementary laws of logic. These laws for any kind of thinking, including medical, have a normative character, since they reflect the objective certainty, differences and conditionality of the phenomena of the material world.
The basic rules of logically coherent medical thinking are revealed in the four laws of logic - the laws of inferential knowledge. The law of identity characterizes the certainty of thinking.
The sequence of thinking is determined by the law of non-contradiction and the law of the excluded middle. Evidence of thinking is characterized by the law of sufficient reason.
The requirements of the logical law - the law of identity - are that the concept of the subject of research (for example, a symptom, nosological unit, etc.) must be precisely defined and retain its unambiguity at all stages of the thought process. The law of identity is expressed by the formula: “ And there is A. At the same time, any dynamic or relatively stable object (a process, a sign of a process) can be thought of under A, if only in the course of reflection, the once taken content of the thought about the object remains constant. In diagnostic practice, the observance of the law of identity requires, first of all, the concreteness and definiteness of concepts. The substitution of a concept, a thesis that reflects the phenomenon under discussion in its essential principles, is common cause fruitless discussions among specialists of various profiles. The value of the law of identity in the diagnostic work is constantly increasing. With the development of medical science, not only the names of many diseases are specified, their varieties are discovered, new means of examining the patient appear, and, along with them, additional diagnostic signs. Often the content of the concepts used in diagnostics (symptoms, syndromes, nosological units) also changes significantly. Changes in environmental conditions and the pace of human activity give rise to diseases that have never been seen before. The law of identity requires constant updating and clarification of the international and national nomenclature of nosological forms, classifications of diseases and their use in everyday diagnostic activities by a doctor of any specialty.
The law of non-contradiction requires consistency in reasoning, the elimination of contradictory, mutually exclusive concepts and evaluations of phenomena. This law is expressed by the formula: "Propositions A is B" and "A is not B" cannot be both true. The violation of the law of contradiction is manifested in the fact that the true thought is affirmed simultaneously and on a par with the opposite thought. More often this occurs when the conclusion about the nature of the disease is based on the analysis of non-specific symptoms and the doctor did not take proper measures to identify the pathognomonic signs of the nosological form. A similar situation arises in cases where the diagnostic hypothesis is based on part of the clinical symptoms and other signs of the disease that contradict the stated judgment are not taken into account. Formal-logical contradictions cannot be confused with dialectical contradictions in objective reality and cognition.
The law of exclusion of the middle, which follows from the law of non-contradiction, is expressed by the formula: "A is either B or not B." This law states that two contradictory statements about the same subject at the same time and relative to each other cannot be both true and false. In this case, one of the two judgments is chosen - the true one, since the third intermediate judgment, which must also be true, does not exist. For example, pneumonia under certain conditions can be either the main disease that led the patient to death, or only a complication of other diseases.
The logical law of sufficient reason is expressed in the formula: "if there is B, that is, as its basis A". The law says that any reason, in order to be true, must have a sufficient reason. The validity of the diagnosis is based on the establishment of symptoms and syndromes specific to a given nosological form, which, in turn, must also be justified. To substantiate the diagnosis, the truths of modern medical science, proven by practice, are used. The most reliable diagnosis will be made by a doctor who constantly uses the latest achievements in practical and theoretical medicine. Violation of the law of sufficient reason continues to be a source of controversy in some modern ideas about the pathogenesis of a number of diseases, as well as difficulties associated with the reproducibility of the same clinical and pathoanatomical diagnosis by different specialists.
The practical verification of the truth of the diagnosis is difficult problem currently. In this regard, the judgment of the correctness of the diagnosis based on the effectiveness of treating patients is of relative importance, since treatment can be independent of the diagnosis in cases where the disease is recognized but poorly treated, or the condition of patients worsens with an unclear diagnosis. In addition, pathogenetic therapy can be effective at certain stages of the course of a large group of diseases that have different etiologies, but some common mechanisms of development. Nevertheless, in terms of observations, even now this method of verifying the truth of the diagnosis can have a positive value.
Much more often, the following two methods are used to identify diagnostic errors (the truth of a clinical diagnosis):
) study of the degree of coincidence of diagnoses of some medical institutions (polyclinics) with the diagnosis of other institutions (inpatient departments of hospitals) - indirect verification of the truth of the diagnosis;
) comparison of clinical and pathoanatomical diagnoses according to a number of parameters determined by the relevant methodological developments- direct verification of the truth of the diagnosis.
However, it should be noted that the effectiveness of clinical and pathoanatomical comparisons (not only at autopsies and subsequent clinical and anatomical conferences, but also on surgical and biopsy materials) depends on a number of objective and subjective factors, primarily determined by the material and technical equipment of the departments of the pathoanatomical service. , the professionalism of the pathologist and the attending physician, the degree of their cooperation in the complex work to identify the essence of suffering, the cause and mechanism of the patient's death.
Nosological form (nosological unit) - a certain disease, which is distinguished as an independent one, as a rule, on the basis of established causes, development mechanisms and characteristic clinical and morphological manifestations.
Also, in modern medicine, antinosologism is widespread, stating that there are only sick people, but there are no diseases.
Thus, we can conclude that an important supporting part of the clinical diagnosis is the knowledge of semiology and the ability to think logically. At the same time, the conscious clinical experience of the doctor, as well as his intuitive specific thinking, are the supporting parts of the diagnosis.
Conclusion
The study and generalization of literary sources on the problem of diagnostics in medicine showed:
Philosophy and medicine for many centuries of their development mutually enrich each other, intersect; as an independent branch of knowledge, the philosophy of medicine becomes especially relevant and developed in the 20th century, when a huge number of research programs appear at the intersection of philosophy and medicine: the practice and technique of treatment, self-healing, self-improvement are developed, taking into account the internal capabilities of the body, the reserves of the human spirit, analyzing and processing best ideas philosophers and physicians.
The problem of cognition is recognized as one of the main philosophical problems. Cognition is an activity aimed at obtaining new knowledge. Mankind has always sought to acquire new knowledge.
The essence of scientific knowledge lies in the understanding of reality, in a reliable generalization of facts, in the fact that behind the random it finds the necessary, regular, behind the individual - the general.
Closely related to scientific knowledge is practical knowledge. The difference between them lies mainly in the target setting. The purpose of scientific knowledge is the discovery of patterns. The purpose of the practice is to create a new thing (instrument, device, medicine, industrial technology, etc.) based on already fully known knowledge. By transforming the world, practice transforms a person.
3. Modern philosophy acts as a methodological foundation of medical knowledge, which is designed to unite disparate private studies and systematically apply them to the study of a qualitatively unique living system - a person.
The task of the philosophy of medicine, of course, does not come down to simply bringing certain provisions of dialectics in connection with medical knowledge, its main goal is to teach students, clinicians to apply dialectics to the analysis of specific natural scientific and clinical factors, and then move from knowledge to the ability to apply dialectics in practice.
4. Diagnostics is a specific creative process, in which not only conscious, but also subconscious thinking is involved, in which intuition has played and will play a certain role, requiring, however, a sufficiently critical attitude towards itself and verification in practice.
A systematic approach, which is typical for modern science in general, is especially important in medicine, because it works with an extremely complex living system - a person whose essence is by no means reduced to a simple interaction of the organs of the human body. In fact, the theory of treatment itself is a specific theory of the management of a living system, since treatment is a system of measures aimed at psychosomatic optimization of the human condition.
Medical diagnostics is not recognition “in general”, but recognition of the Disease, its Name.
The development of modern medical technology has a pronounced tendency to "deepen" the system-structural level of diagnostics. But no matter how deeply we penetrate into the cellular, subcellular, molecular and so on structural levels, we can draw conclusions and conclusions only at the organismic level. Deepening knowledge about the specific mechanism of pathological changes at the molecular-cellular level does not lead to knowledge of the causes of the pathology of the body.
Medical diagnostic thinking is not exhausted by the laws of formal logic: the laws of identity, exclusion of the third, non-contradiction and sufficient reason are quite conditionally feasible in medicine.
Causal relationships in medicine are established rather conditionally, and the relationships themselves are ambiguous: the same cause can cause different effects, and the same effect can occur due to different reasons. No factor by itself can cause disease.
Thus, diagnostics is a specific cognitive process, and without constant reliance on the philosophical doctrine - the general methodology of science, it is almost impossible to create a single coherent theoretical base of modern medicine from disparate facts.

It is unlikely that a primitive man, living in caves and constantly hunting for animals, does not have any “benefits of civilization” at his disposal (now I don’t mean what is usually meant by the benefits of civilization, but unfortunately I can’t find a worthy equivalent to this) was able to philosophize. And the point here is not only in his insufficiently adapted brain apparatus for this.
And vice versa, science (real science) without philosophy is doubly impossible, since scientific discoveries (and just scientific work) must be realized, comprehended, experienced, otherwise these will not be discoveries, but will be simple mechanical work to extract, take away from Nature new ones, dead knowledge. Dead knowledge cannot give a person anything good. That is why a real scientist should be, first of all, a philosopher, and only then a natural scientist, experimenter, theorist.
Of course, the fact that science does not think rationally should lead to differences in truths: philosophical truth and scientific truth. Scientific truth is objective knowledge. It makes a person richer in material terms, stronger, healthier, maybe even increases his self-esteem. That is, it is purely material in its manifestations. Philosophical truth, even in its manifestations, is non-material, since it is, first of all, a certain product of the activity of human consciousness, moreover, its rational and moral sphere. It seems to me that the following statement, with which I agree, really reflects a philosophical truth: “... Since the activity of rational thought directed at a thing, at an object, leads to an understanding of this thing, this object, then understanding is the truth of the activity of the mind. Further, since rationality is firmly connected with its “sensory flesh”, with the activity of the moral feeling, the product of the activity of the consciousness determined by this feeling is good. Therefore, philosophical truth is also good. Since rationality and morality are one in their consciousness, then the truth of the latter, therefore, is good UNDERSTANDING, or understanding GOOD.
Medicine in the system of sciences is a kind of problematic field of natural science, social science and the humanities, primarily philosophy. The latter contributes to the improvement of the conceptual apparatus of all practical health care. Moreover, it develops the doctor's scientific and ideological views and heuristic (creative) potential in an integral system of material and spiritual culture of physicians. And in general, as practice shows, without philosophy, the image of medicine itself as the most important sphere of human culture noticeably fades. Medicine, together with philosophy, comprehends the complex world of human life, manages his health. At the same time, she herself becomes the object of special philosophical knowledge. The general contours of medicine in the criteria of ancient philosophy were outlined by the great Hippocrates. Making medicine into an independent natural-science and humanitarian sphere of influence on a person dates back to the New Age, when it began to organically associate with the philosophical concepts of life, the philosophy of F. Bacon, I. Kant and other thinkers.
Scientific and medical (theoretical) knowledge historically originated along with the philosophical teachings of the ancient Greeks. Starting with the awakening of interest among thinking doctors in the philosophical comprehension of the root causes of the world, the place and role of man in it, medicine began to be actively saturated with philosophical meaning. A little later, doctors also had a stable mental need for a holistic (volumetric) view of the systemic bodily-spiritual essence of a person. In the end, a dialectical relationship was naturally formed between the philosophical understanding of the nature, role and purpose of man and the emerging clinical thinking, which seeks to explain sometimes paradoxical phenomena in human life.
Philosophy actively helps physicians to look at many things they know differently, to see the invisible, that is, to understand the inner meaning of objects and phenomena. “Research in medicine,” said the Canadian pathophysiologist and endocrinologist Hans Selye, “is to see what everyone sees, but think in a way that no one thinks.”
Medicine owes this ability to philosophy, which provided it with a special (object-conceptual) method of clinical thinking. They could develop fully only together. They have one object of knowledge (a person) and the same practical interest - the state of a healthy lifestyle as a result of the action of many subjective and objective factors. Without medical and philosophical knowledge today, in principle, such public spheres of life as economics and politics, the education system and sports, culture, and so on cannot function normally and improve. Medical knowledge is a link between culture, man and his life.
((The problem of obtaining accurate or true knowledge has become key in the knowledge . Some see in the truth the correspondence of knowledge to reality, others believe that it reflects the usefulness of knowledge for life. Still others see an agreement or scientific consensus among scientists on the use of knowledge in practical life to transform nature, society and oneself into them. True knowledge allows people to correctly assess the environment and consciously build their lives, focusing on possible changes and transformations. The path to truth is the search for those fixed in life experience and cognitive activity of human properties and relationships in the object of knowledge. Neither the object nor the subject of knowledge exist without its subject, which is a society of people or a person. The subjective side of cognition is due to the fact that a single cognizing subject acts as a specific historical factor that makes it possible to discover true knowledge and make it the property of all. any truth has moments that perfectly adequately reflect the state of various aspects and spheres of the object. So, these include the date and place of the event, as well as theoretical evidence that is irrefutable. Such a truth expresses complete and accurate knowledge about the object of knowledge, i.e. full correspondence of knowledge to the subject, phenomenon, process. It is believed that the criterion of truth is practice, which, like knowledge, is part of the universal culture. In science and especially in medicine, along with understanding the concept of truth as reliable knowledge, the concept of “fact” is actively used, as a special kind of knowledge that fixes the empirical result of the initial study. All empirical facts eventually became the starting point of research or scientific facts. This means that when a scientist wants to prove whether this or that statement of his is true, he must refer to the fact on which it is built. If there is such a fact, the statement is true; if it is not, it is false. .Facts make up material of science. The scientific value of a fact lies in the fact that it gives the scientist a basis for theoretical thinking. According to Popper, the status of truth can be compared, as it were, with a mountain peak, which is always in a fog. However, this does not in any way affect the existence of the peak itself. Thus, in objective truth, the world is revealed as it really is, regardless of the person himself and his consciousness, although elements of subjectivity are always present in truth. But subjectivity should by no means be associated with delusion. Misconceptions appear not so much because of the wrong choice of ways to solve a scientific problem, but because of a lack of information, information. This is characteristic of medicine. If earlier many diseases could be prevented and treated "in one way or another", depending on the experience and skill of the doctor, now this can and should be done only "in this way and not otherwise." The number of options for combating the disease, as knowledge about the essence of a particular disease deepens, should progressively decrease, gradually approaching the only, most effective one.))
Methods of knowledge in medicine.
Hippocrates argued that a clear knowledge of human nature is not borrowed from anywhere, but only from medical art. The specificity of knowledge in medicine at the level of the subject of knowledge lies in the fact that the breadth of its cognitive interests extends from molecular level human morphophysiology to the social patterns of the human community. She develops high-precision methods of surgical interventions (for example, on the brain). And in urgent situations, it is necessary to quickly take effective measures, when an analytically accurate study is excluded and impossible.
Diagnostic cognition is inherently prerequisite, and also has the character of inferential knowledge penetrating “beyond” concepts, measurement data. Taking into account the presence of a cognitive-value attitude in such cognition, it can be argued that diagnostics as a process of cognition contains an exploratory attitude to choose the most important features and eliminate secondary ones when they are summed up as a symptom. That is, a feature of the clinical empirical knowledge is that it has certain methodological prerequisites, "theoretical loading". This suggests that, firstly, empirical clinical knowledge at each stage is mediated by the theoretical level of knowledge and, secondly. That there is a dependence of the meanings of terms on the corresponding theories. on which the applied methodology is based.
Measurements in medicine are the main tool of knowledge. Measurements are complex theoretical, experimental and practical research. It is possible to single out the measurement of physical quantities on non-biological and biological objects, the measurement of medical and biological quantities proper, psychometry and medical sociometry.
Increasing knowledge intensity, intensification, computerization and rationalization of modern medicine are the basis for qualitative changes in methods and epistemological attitudes in medicine. If until recently the means for obtaining medical information only increased the amount of data, complementing the clinic, now it opens up new ways in research and diagnostics. The main trend in these changes is the objectification of the data obtained.
Thus, technique and technology influence the nature of the very medical knowledge of the norm and pathology and the nature of the use of this information.
The ultimate goal of knowledge is truth. In the evaluation of the process of cognition. Eg. the correctness of the diagnosis, the key role belongs to practice, which is the ultimate goal and criterion of the truth of knowledge.
