The communist hypothesis remains the good one, I do not see any other. If we have to abandon this hypothesis, then it is no longer worth doing anything at all in the field of collective action. Without the horizon of communism, without this Idea, there is nothing in the historical and political becoming of any interest to a philosopher. Let everyone bother about his own affairs, and let us stop talking about it. In this case, the rat-man is right, as is, by the way, the case with some ex-communists who are either avid of their rents or who lost courage. However, to hold on to the Idea, to the existence of this hypothesis, does not mean that we should retain its first form of presentation which was centered on property and State. In fact, what is imposed on us as a task, even as a philosophical obligation, is to help a new mode of existence of the hypothesis to deploy itself.
