Asked to prove a questioner's existence, Morgenbesser shot back, "Who's asking?" - Sidney Morgenbesser

During a lecture, the Oxford linguistic philosopher J. L. Austin made the claim that although a in English implies a positive meaning, there is no language in which a double positive implies a negative. Morgenbesser responded in a dismissive tone, "Yeah, yeah."

Morgenbesser described ethics as entailing “ought implies can” while in Jewish ethics “can implies don’t.”

Of Hilary Putnam – "He’s a quantum philosopher. I can’t understand him and his position at the same time."
