The Pavlovian session (Russian: Павловская сессия) was the joint session of the USSR Academy of Sciences and the USSR Academy of Medical Sciences held on June 28 to July 4, 1950. The session was organized by the Soviet Government headed by Joseph Stalin in order to fight Western influences in Russian physiological sciences. During the session, a number of Ivan Pavlov's former students attacked another group of his students (Leon Orbeli, Pyotr Anokhin, Aleksey Speransky, Ivan Beritashvili) whom they accused of deviating from Pavlov's teaching. As the result of this session, Soviet physiology excluded itself from the international scientific community for many years.
== Preceding events == The Pavlovian session followed a sequence of Stalin's interferences in academic affairs during the post-war time:
In 1947, Georgy Aleksandrov asked Stalin to review his textbook for university students entitled "History of West European Philosophy". Stalin criticized the book as an attempt to analyze philosophy from a pro-Western position rather than using the principles of Marxism–Leninism. In 1948, Stalin strongly supported Lysenko's work on the inheritance of acquired characteristics in plants which has now been discredited. Lysenko's research was thought to hold the promise of strengthening the Soviet Union's agriculture. In 1949, Stalin declared an opposition to cosmopolitism. Great Soviet Encyclopedia defined cosmopolitism as a "reactionary bourgeois ideology of rejecting national traditions and national sovereignty by preaching indifferent relationship to one's country and national culture and advocating the establishment of a 'world government' and 'world citizenship.' " In 1949, Stalin commented on the issues of linguistics, in particular he criticized the view that language was a derivative of an economic base. Stalin also stated that "no science can develop and flourish without a battle of opinions, without freedom of criticism." The interference in physiology, psychology and psychiatry was initiated in the summer of 1949 when Stalin instructed the Minister of Health Yefim Smirnov to hold a session on Pavlov's teachings. On 28 September 1949, on the eve of the 100th anniversary of Pavlov's birth, Yuri Zhdanov reported to Stalin about the "serious trouble" with the development of Pavlov's teaching and put the blame on Orbeli, Beritashvili, and arrested Stern. In replying to this report, Stalin wrote: "In my opinion, the greatest harm to Academician Pavlov's teaching was done by Academician Orbeli... The sooner Orbeli will be exposed and the more thoroughly his monopoly will be eliminated, the better. Beritov and Stern are not so dangerous because they oppose to Pavlov openly and thus facilitate the reprisal of science against these amateurs of science... Now something about the tactics of the struggle against the opponents of Academician Pavlov's theory. At first, it is necessary to stealthily collect Academician Pavlov's supporters, organize them, assign roles, and only after this to gather the session of physiologists... where it will be necessary to give decisive battle to the opponents. Without this, it can fail. Remember: the enemy should be firmly beaten, with reliance on complete success." Georgy Malenkov supervised the organization of the meeting.
== Keynote speeches == Four keynote speakers outlined the main topics of the session: Sergey Vavilov, the President of the USSR Academy of the Sciences; Ivan Petrovich Razenkov, the vice-president of the USSR Academy of Medical Sciences; Konstantin Bykov, the Director of the General Physiological Department at the Institute of Experimental Medicine; and Anatoly Grigorievitch Ivanov-Smolenskiy, a psychiatrist.
=== Vavilov's speech === In his inaugural address, Sergey Vavilov, praised Stalin and Pavlov for their materialistic approach to the problem of relationship between the material and mental. He stated that Pavlov was a great scientist whom Stalin and the Soviet Government esteemed very highly. Vavilov noted that Soviet physiologists had made great achievements since Pavlov's death, but some did not follow Pavlov's teaching and even attempted a revision of Pavlov's views. Open or concealed opposition to Pavlov's materialistic theory was expected and quite understandable for bourgeois scientists who suggested that Pavlov's theory of conditioned reflexes should be shelved and only his experimental methods might be useful. However, even Soviet scientists did very little to develop important trends suggested by Pavlov. For example, experts who participated in a broad discussion of materialistic linguistics in Pravda did not even mention the role of Pavlov's theory in the study of language. Vavilov explained that the goal of the joint session of physiologists and psychiatrists was to conduct "a critical and self-critical examination of how matters stand with regard to the development of Pavlov's legacy in the Soviet Union". He concluded: "There can be no doubt that it is only a return to Pavlov's road that physiology can be most effective, most beneficial to our people and most worthy of the Stalin epoch of the building of Communism. Glory to Pavlov's genius! Long live the leader of peoples, our great scientist and preceptor in all our major undertakings, Comrade Stalin!"
