Abstract
The paper aims to show how the tragic and dramatic elements of Thus Spoke Zarathustra become essential components of the transcendental empiricism in Difference and Repetition, by actualising a virtuality that was inherent in the Nietzchean book but not made explicit by its author. If the meaning of the eternal return is hidden in the four books of Thus Spoke Zarathustra, and if the Deleuzian reading does not aim to interpret and express the interiority of a text, but to machine it, then what Difference and Repetition seeks is something other than the Nietzschean intention. And it is precisely on the basis of this hidden otherness - something that Nietzsche had not (yet) expressed - that Deleuze machines Zarathustra with other texts and other authors. The paper will analyse this experimentation as the concretisation, within Deleuzian philosophy, of the repetition of power that makes Deleuze's Nietzschean May 68.
