The seventh treatise of the cycle "Ontological and epistemological bases of medicine and physiology" (finishing). It is marked that the medical science of the end 19 and the beginnings of 20th centuries began to depart from the concept of the individuation of the doctoring process, which was considered almost officially a basis of a clinical paradigm throughout 23 centuries. To the middle of 20th century this conception has been justified by rapid development of biology and by requirement to use of its achievements in medicine. Nowadays we can observe excessive differentiation of clinical medicine (which is the doctoring science). The individuation principle implicitly underlies any national systems of public health services, and it forms a philosophical basis of a medical science. This principle expresses specificity of physician’s thinking which depends a little from the paradigm declared by representatives of official medicine. This principle lays in basis of the differentiation of public health (as the system of physicians' activities), and in basis of differentiation of medical science (as the clinical disciplines' system). The public health decides problems of society's health for interests of the society by regulation of efforts of doctors in limits of the different profiles. And the public health promotes tendency of any doctor in order to professionally promote interests of health of each patient in each clinical case. Therefore and physician practice of any profile is effective if it supports the doctor's aspiration as much as possible to keep and strengthen health of each patient (if he/she is healthy), and to recover him/her health (if he/she is sick). The medical science is effective so far as it follows this principle within the limits of each of medical disciplines. Thus the doctor reaches best efficiency of doctoring only on the basis of a clinical paradigm, and this efficiency does not depend directly on a biomedical paradigm which is declared by official medicine as basic one in the doctoring science.Keywords: an individuation of doctoring; a clinical paradigm; public health; a medical science; public health services profile; differentiation of medical science.
