Describes how individuals and their world come into being from the transcendental field of singularities as the first stage of the genesis. This stage gets engendered by sense. It's with reference to Leibnez's theory of the monad and of compossible and incompossible worlds. The second stage establishes and develops the Ego or Person on top of the first stage. The first stage comprises an umwelt. Good sense gets actualized here. In the second stage the person sees more objectively across individual worlds forming a welt.Deleuze's formulations resemble the Many Worlds interpretation of Quantum Physics. He uses the same literary example they do, The Garden of Forking Paths by Jorge Borges.
