From ABC PRIMER. Deleuze is talking about Wittgensteinians. I have replaced with OOO to bring out the contemporary relevance:
For me, it’s a philosophical catastrophe. lt’s the very example of a ”school,” it’s a regression of all philosophy, a massive regression. The OOO matter is quite sad. They imposed a system of terror in which, under the pretext of doing something new, it’s poverty instituted in all grandeur… There isn’t a word to describe this danger, but this danger is one that recurs, it’s not the first time that it has happened. lt’s serious, especially since OOOxians are mean and destructive. So if they win, there could be an assassination of philosophy. They are assassins of philosophy.
