“This sort of thing has got to be stopped. Bad philosophers are like slum landlords. It's my job to put them out of business.”

“In philosophy it is always good to put a question instead of an answer to a question. For an answer to the philosophical question may easily be unfair; disposing of it by means of another question is not.”

“The philosopher is not a citizen of any community of ideas, that is what makes him a philosopher.”

“Philosophers are often like little children, who first scribble random lines on a piece of paper with their pencils, and now ask an adult 'What is that?”

“Our craving for generality has [as one] source … our preoccupation with the method of science. I mean the method of reducing the explanation of natural phenomena to the smallest possible number of primitive natural laws; and, in mathematics, of unifying the treatment of different topics by using a generalization. Philosophers constantly see the method of science before their eyes, and are irresistibly tempted to ask and answer in the way science does. This tendency is the real source of metaphysics, and leads the philosopher into complete darkness. I want to say here that it can never be our job to reduce anything to anything, or to explain anything. Philosophy really is “purely descriptive.”

“Most of the propositions and questions to be found in philosophical works are not false but nonsensical.”
