[The physician-philosopher - Donat Semenovich Sarkisov. To the 90 anniversary since birth].

The huge and promptly increasing volume of the actual material of modern biology and medicine without its systematization doesn't develop any more, and slows down development of science. The science as the work which are explaining world around needs to bring a system in chaos of the facts. This can be done only on the basis of the philosophy of dialectical materialism, which allows an objective, realistic to create theoretical generalizations of the ocean of particulars. Donat Semenovich Sarkisov who agreed the main phenomena of the general pathology with modem biological sciences, modern clinical practice, materialistic dialectics was the genial philosopher.
