The historical meaning of the dissolution of the Soviet Union and of the subsequent post-communist transformation remains profoundly unclear. Most observers hesitate to designate these events as a revolution, building on a common-sense notion of revolution as a violent, radical change. My dissertation argues that the post-communist transformation was indeed a revolution and proves this claim by comparing it with the French Revolution, in its political, social, and anthropological aspects. In both historical cases, the quick and easy victory of society (...) over the "old regime" was followed by a long period of internal struggle, threat of stagnation, and widespread melancholia. ;Based on this historical parallel, I turn to the theoretical analysis of the concept of revolution. Our recent historical experience allows for a new perspective on the history of this concept, as it has been developed in the Modern philosophy and political theory. The present study focuses primarily on two points in this history. The first is Immanuel Kant's treatment of the French Revolution in his late political texts, The Conflict of the Faculties and The Metaphysics of Morals. The second is Hannah Arendt's work On Revolution. The close reading of these texts allows me to outline the structure of the concept of revolution as centered around the logic of negativity. ;Kant interprets the French Revolution as an irreversible event. The revolution repeatedly returns to the imaginary, impossible point of self-foundation only to recoil again from the abyss it opens. Arendt also emphasizes the two sides of revolution, the infinite self-destruction and the new beginning. Although Arendt attempts to separate the "positive" American Revolution from the "negative" French Revolution, the dissertation shows that her conceptual reading of the two is identical and that it heavily depends on the narrative structure of tragedy. ;Revolution is the central concept of the Modern philosophy of history. It is far from being outdated but must be updated and renewed to provide meaning to our present historical situation. This dissertation makes a step towards this renewal. (shrink)
