"Linus Pauling, so great a scholar and humanist that he was to win two Nobel Prizes, had already written a leading chemistry text—just as the great Richard Feynman was later to publish classic physics lectures. William James had long since published his great Principles of Psychology. Richard Courant, top dog at Gottingen in Germany, had not been to proud to author an accurate textbook on calculus. Who was Paul Samuelson to throw stones at scholars like these? And, working the other side of the street, I thought it was high time that we got the leaders in economics back in the trenches of general education."
