In the paper a number of problems are discussed from the history of medicine--from ancient times up to the present days. The positive experience is pointed out of the centuries-long development of medicine and its enormous significance for the education and correct thinking of the doctor of today. History of medicine is considered as a living source of an exact ethics and doctrinary behaviour, as a powerful beacon enlightening the present and future of medical practice. The author supports the statement that the marxism-leninism philosophy is the only one securing correct medical thinking and action and the only one that might provide for eliminating the blind doctrinairism and various narrow-minded deviations from the research work and practice.
