hope we shall not have exhausted the theme of criteria for historical-scientific knowledge, and that this will be the subject of further productive discussions.Though A. M. Etkind may have repressed (in Freudian fashion) his recollection of this, I recall that once a perversity of fate brought him from the V. M. Bekhterev Petersburg Scientific-Research Psychiatric Institute to the Institute of History of Natural Science and Technology of the USSR Academy of Sciences, where I was, at the time, head of the section on the psychology of scientific creativity. Inasmuch as I knew Etkind to be a thoughtful and serious specialist in problems of psychopathology and was, moreover, pondering how to join most effectively his knowledge and experience with the profile of our institute, which was far removed from that of a clinic, I recommended to him that he turn to the history of psychoanalysis in Russia.For long years this was a closed subject. But times have changed. On the initiative of Academician P. L. Kapitsa, I began to prepare Sigmund Freud's lectures for publication (true, to get to the point where they would be published required ten years; and despite Petr Leonidovich, the book was refused for publication in the series [Classics ofscience]).
