ABSTRACT
This chapter attempts to study a second series of categories relating to time, after briefly discussing the rôle of the idea of time itself in the philosophies of existence. The time-categories to be studied are: first, the concepts of possibility and project; second, the concept of origin or source especially as developed by Jaspers; third, the three concepts of situation and the instant. Several contemporary schools of philosophy, and pragmatism in particular, have been described as time-philosophies. The term is also applicable to the philosophy of Bergson and to the philosophies of existence. Kierkegaard invites to go back to what is pristine, to what is primitive, to what is primogenial. He believes that existence should recover its eternal primitivity. The primal dimension of time, for the philosophers of existence, is the future. Thus Heidegger, no doubt in a different way and in a wholly different domain, would have us hark back to the earliest Greek philosophers.
