The article presents a theoretical analysis of the extramural polemic between Slavoj Žižek and Evald Ilyenkov, undertaken in the context of the search for the foundational underpinnings of the two philosophers’ perspectives on the limit-logical definitions of being. It shows how this apparently “abstract” search grows out of the socio-historical circumstances of the thinkers’ lives, which are inscribed in the dramatic conditions of existence of the political events of the twentieth century. The active life-political position of the follower of Marx’s (...) ideas, figuratively expressed in the text by Lenin’s term “tactics of social democracy” (Lenin 1962), is justified by one or another cognitive position: the unified attitude “not to explain but to transform the world” breaks down into various “tactics” precisely in the attempt to solve the problem of radical negativity (as Žižek formulates it). This is expressed in the division of Marxism into “Western” and “Eastern”. This article analyzes the legitimacy of such a division and shows the conditions for a disintegration of the divide. The relation of Ilyenkov and Žižek to Hegel’s works turns out to be the key to understanding this division, and consequently to the essential difference in socio-political attitudes and “tactics”, of which they are creative representatives. The analysis leads to the formulation of the “germ cell” of disagreement between Ilyenkov and Žižek—the problem of the universal—which unfolds in the difference between the thinkers’ positions on certain theoretical points. The limitation of Ilyenkov’s position, established under the fire of Žižek’s criticism, is removed, according to the author, by the development of a new category of “fractality”, which acts as a counterpart to the main dialectical category of “totality” and provides a concrete (in the Hegelian sense) solution to the problem of radical negativity in the spirit of the classical philosophical tradition.
