Although I have already identified Nietzsche as the crucial figure for Deleuze’s affirmationism, and we could also nominate Spinoza, I want to suggest the role of Bergson as truly influential. As we will see it is Bergson’s critique of the negative that underpins the consistency of Deleuze’s affirmationism, which later acquires Nietzschean or Spinozan accents.
