Keynesian contempt

"[John Maynard Keynes] was much too self-assured, convinced that what other people could have said about the subject was not frightfully important. . . . There was a period just after he had written The General Theory when he was so convinced he had redone the whole science that he was rather contemptuous of anything which had been done before. . . . His own opinion was that he could re-create the subject, and he rather had contempt for most of the other economists."
-- F.A. Hayek
