[Foucault] may perhaps have meant that I was the most naive philosopher of our generation. In all of us you find themes like multiplicity, difference, repetition. But I put forward almost raw concepts of these, while others work with more meditations. I’ve never worried about going beyond metaphysics…I’ve never renounced a kind of empiricism…Maybe that’s what Foucault meant: I wasn’t better than others, but more naive, producing a kind of art brut, so to speak, not the most profound but the most innocent.
