Morgenbesser. Bless him!

When challenged why he had written so little, he fired back: "Moses wrote one book. Then what did he do?"[1][2]

When asked his opinion of pragmatism, Morgenbesser replied "It's all very well in theory but it doesn't work in practice."[2]

During a lecture the Oxford linguistic philosopher J. L. Austin made the claim that although a double negative in English implies a positive meaning, there is no language in which a double positive implies a negative. To which Morgenbesser responded in a dismissive tone, "Yeah, yeah."[1][2]
