Abstract
As we tend to forget the distinction between polemic and critique, readers of Castoriadis are often unaware of his frequent returns to a reading of Marx. In looking at the essays collected in the six volumes of Crossroads in the Labyrinth, it is useful to distinguish between, on the one hand, the political polemics launched against the failure of a Marxist Left, and on the other, the critiques of a Marx who is seeking to understand the sociohistorical meanings underlying a rationality that is new only in appearance, thereby reviving traditional philosophical interrogation. Today, as Marxism has become merely a philosophy while, as a political movement it has lost its anchor, it is worth coming back to the meeting point between Marx and Castoriadis. This can also serve to revive our appreciation of the project of philosophy in general.
