ABSTRACT
In this essay I want to provide some insight into the distinctive features of a Bergsonian mode of thinking. I will begin by introducing some of the essential features of duration. These may initially strike the reader as abstruse and possibly mystifying. By the end of the volume I hope they will strike the reader less so. Our starting point and persistent source of inspiration is this comment from Deleuze:
In Time and Free Will the fundamental idea of virtuality appears, which will be taken up again and developed in Matter and Memory: duration, the indivisible, is not exactly what cannot be divided, but what changes in nature in dividing itself, and what changes in this way defines the virtual or the subjective. But it is above all in Creative Evolution that we will find the necessary information.
