[1] In April 1954, the theses "On the question of the relationship between philosophy and knowledge about nature and society in the process of their historical development" appeared, the authors of which were Ilyenkov and Valentin Ivanovich Korovikov.

In February and March 1955, at the Faculty of Philosophy of the MSU, an inspection was carried out on them by the commission of the department of science and culture of the CPSU Central Committee.

In the commission's report, the theses of Ilyenkov and Korovikov were assessed as "a relapse of Menshevik idealism, which was long defeated and condemned by the party”  and It was found that “some students and graduate students have a desire to move away from pressing practical problems into the area of "pure science", "pure thinking", divorced from practice, from the politics of our party.

In the first half of the 1960s, Ilyenkov participated in the creation of the Philosophical Encyclopedia as an author; in the process of working on the second volume, he became the editor of the section "dialectical materialism".

[1] From 1975 until the end of his life, Ilyenkov led a scientific seminar at the Faculty of Psychology of Moscow State University at the invitation of Dean Aleksei Leontiev.

[5] Evald Ilyenkov did original work on the materialist development of Hegel's dialectics, notable for his account of concrete universals.

David Bakhurst wrote in his article; "Meaning, Normativity and the Life of Mind": Ilyenkov was important in the revival of Russian Marxist philosophy.

His influence can be witnessed in the international research effort concerned with the publication of Marx' economic manuscripts (in Marx/Engels: Gesamtausgabe, or MEGA, section II, 1976 ff.).
