 Deleuze’s historical monographs were, in a sense, preliminary sketches for the great canvas of Difference and Repetition (1968), which marshaled these resources from the history of philosophy in an ambitious project to construct a “philosophy of difference.” Following Maimon’s critique, Difference and Repetition produces a two-fold shift from the Kantian project of providing the universal and necessary conditions for possible experience. First, rather than seeking the conditions for possible experience, Deleuze wants to provide an account of the genesis of real experience, that is, the experience of this concretely existing individual here and now. Second, to respect the demands of the philosophy of difference, the genetic principle must itself be a differential principle.
