The Threefold Root of Temporality

The question of the nature of time is as old as philosophy itself. Before philosophy, time was not problematized, it was a pure common-sensical matter. There were various experiences of time, and, accordingly, different words to name it. Whitehead's solution of the temporal conundrum lies in the concept of "creative advance of nature" that is systematically elucidated only in Process and Reality (1929).To understand the creative advance of nature, one needs to interpret the togetherness of its three aspects —creativity qua concrescence, effi cacy qua transition, vision qua initial subjective aim—, and this provides us with the core meaning of time: (i) genuine novelty appears in the World, (ii) past events are, so to speak, ontologically memorized, and (iii) there is an upward trend in terms of “intensity” of events. These three complementary requirements refresh in their own way the Greek triple understanding of time: time is “aiôn,” lived duration (outside physical time) and destiny, but it is also “chronos,” causal time, and “kairos,” timeliness or the appropriate moment for action.
