Abstract
In order to revisit the question of the nature of time in the context of the present volume, it is advisable to probe successively the following issues. 1.What is time, respectively for philosophy, science, and technoscience? 2. How have its foundations been shaken by Einstein’s relativities, Bergson’s duration and Whitehead’s creative advance? 3.What are the available data? 4.What method should one use to make sense out of them? 5.What is the outcome of their processualization? In conclusion, we highlight the threefold root of temporality disclosed in Whiteheadian organicism.
