The vast empirical material on pathogenesis of diseases has thus far been accumulated. However, its systematization and philosophical interpretation have not been given due attention since the time of I.V. Davydovsky. The value and topicality of I.V. Davydovsky’ ideas need a fresh view andfurther development in the context of knowledges of the XXI century. The analysis of the selected provisions of I.V. Davydovsky offered in the article will hopefully contribute to their introduction into applied medicine.

The author presents the clinical and methodological analysis of the problem of medical errors based on the empirical data obtained in the 20 century. Relevant theoretical premises having applied implications are substantiated.

The experience of expired century was used as a basis of presenting certain philosophical and sociological foundations of sociology of physician. The main methodological defects of comprehension of the system “physician-patient” are revealed. The particular methodological aspects of status position of physician in social space are exposed. The original structure of status of physician is proposed as oneness of one's social (personality) and biological (individual) aspects. The absolute and relative differences of status of physician from other social units are described.

Based on the study of more than 40 classifications of the causes of diagnostic errors, a classification of the main deontological factors involved in the occurrence of diagnostic errors has been compiled. A special technique was used to study the material 601 of the case history with diagnostic errors. It turned out that in 78.4% of the sources of medical errors in one way or another were deontological factors (insufficiently collected information about the patient or. Its incorrect interpretation).
