similar research, was called "dialectical logic". Vladislav Lektorsky connects the turn of Zinoviev and Ilyenkov to the study of theoretical thinking and methodology with the conviction that strict knowledge can influence bureaucratic "real socialism" and reform the Soviet system. According to Pavel Fokin, appeal to logic was an act of self-preservation in the conditions of Soviet reality, unwillingness to engage in ideological propaganda within the framework of historical materialism – logic was outside of party or class interests. In 1952, Zinoviev and his students Grushin, Mamardashvili and Shchedrovitsky established the Moscow Logic Circle. The participants tried to develop a so-called "genetically meaningful" logic – an alternative to both semi-official dialectical logic and formal logic. The activity of the circle took place against the backdrop of the revival of the atmosphere at the philosophical faculty after Stalin's death. At the beginning of 1954, a discussion was held on "Disagreements on Logic Issues", which divided "dialecticians", formal logicians and "heretics" from the circle – the so-called "easel painters".

The opposition of the "old men" was counterbalanced by the support of the Minister of Culture Academician George Alexandrov, which he managed to get through Karl Kantor. The opponents were Teodor Oizerman and Pavel Kopnin, the post-graduate students Mamardashvili and Grushin and Schedrovitsky supported the defense of Zinoviev. The text of the dissertation was later distributed in numerous reprints in samizdat and was published only in 2002. The peripetias of those events Zinoviev grotesque described in the novel "On the Eve of Paradise". In 1951, Zinoviev married, in 1954, his daughter Tamara was born, a year later, the couple received a small room in a communal flat. The marriage was partly calculated (Tamara Filatieva was the daughter of a People's Commissariat for Internal Affairs worker), partly out of love, but family life did not work out – each
