DELEUZE ON HAVING DIALOGUES
It is already hard enough to understand what someone is saying. Discussion is just an exercise in narcissism where everyone takes turns showing off. Very quickly, you no longer have any idea what is being discussed (TWO REGIMES OF MADNESS, 384).
Every philosopher runs away when he or she hears someone say, “Let’s discuss this.” (WHAT IS PHILOSOPHY, 28)
Communication always comes too early or too late, and when it comes to creating, conversation is always superfluous (WIP, 28).
Discussion amounts to wasting a lot of time on indeterminate problems. Conversation is something else entirely. Conversation is quite necessary. But the slightest conversation is a highly schizophrenic exercise happening between two individuals with common resources and a taste for ellipse and verbal shortcuts. Conversation is composed of immobility interspersed with long silences; it can give you ideas. But discussion has no place in philosophical work (TRM, 384, translation modified by me).
