This is Deleuze being dismissive of Wittgenstein in his ABC of Philosophy. I wonder what got on his goat so much? Harsh, but funny!
Couldn't find any subtitles, translation requires vigilance.
Int: Okay, moving on to W. And, W?
Deleuze: There is nothing in W.
Int: If there is Wittgenstein, I know it’s nothing for you, but just one word?
Deleuze: Ah no, I do not want to speak of it...For me, this is a philosophical catastrophe, it is a type of ‘school’, which is a regression of all of philosophy, a massive regression of philosophy. The Wittgenstein affair is very sad. They have forced, where under the pretext of doing something new, a system of terror (chuckle), but it is, poverty dressed as grandeur. In French, there is no word for expressing this danger here; it is a danger that returns, this is not the first time, it is recurring. This is grave, they are nasty the Wittgenstenians, and since they destroy all, in this, there could be an assassination of philosophy; these are the assassins of philosophy.
Int: That serious?!
Deleuze: Yes, Yes... It is necessary for great vigilance. [Laughs]
