Mary Warnock on Thinking

From the chapter Materialism and Relativism in Hilary Putnam's Renewing Philosophy:

Mary Warnock once said that Sartre gave us not arguments or proofs but "a description so clear and vivid that when I thinhnk of his description and fit it to my own case, I cannot fail to see its application." It seems to me that this is a very good description of what Wittgenstein was doing, not just in the private language argument, but over and over again in his work.
