The paper aims to describe the stakes of a Nietzschean influence on Deleuze's reflections on the transcendental and conversely to highlight the Deleuzian operation of politicising Nietzsche by ‘minorising’ him. In order to further understand such a complex relationship of becoming between Deleuze and Nietzsche, the first objective of the paper is to focus on active and reactive forces, which seem to be the core of this very relation. Thus, the paper suggests that micropolitics has its conditions of possibility in (...) the Nietzschean corpus and, in particular, in the symptomatology of decadence, resentment and nihilism. In this sense, now the title of the paper reveals its meaning: the whole Deleuzian operation could be summarised as the passage from the criticism and questioning of an image of Nietzsche ‘forbidden to minors’, typical of the interpretations of the first half of the twentieth century, to a becoming-minor of these very same Nietzschean concepts. It is precisely through such a becoming-minor that Nietzsche's diagnosis and concepts are translated in a political and emancipatory key, in order to give power to minorities. (shrink)
