Abstract
The author examines the philosophical doctrines of Kant and Hegel, and puts forward a thesis concerning the inner ambivalence of these doctrines. The thesis is supported with concrete examples demonstrating the internal contradictions in the philosophical systems of Kant and Hegel. The more a philosophical doctrine is meaningful and innovative, the more it is contradictory, ambivalent, and aporiastic, in spite of the efforts of its founder and followers to reconcile all of its major claims. This ambivalence, however, turns out to be a positive quality, because it allows philosophers to transcend their philosophical system, and if not directly, then indirectly raises the questions: Should philosophers continue building systems? And do not all self-contained systems fetter philosophical discourse?
