Given my recent exchange in "E-Mail to the Editors" with Gene Epstein of Barron's, I was especially tickled by the following anecdote from The Economist as Savior:

In 1931 Friedrich Hayek gave a lecture at Cambridge explaining his view of how to deal with the Depression--that "the quickest cure would be for people to save more, to bring about a recovery in investment." ... His exposition was greeted with complete silence, but Richard Kahn [one of those who helped Keynes develop his own ideas], who was in the audience, felt he had to break the ice. "Is it your view," he asked Hayek, "that if I went out tomorrow and bought a new overcoat, that would increase unemployment?" "Yes," replied Hayek, turning to a blackboard full of triangles, "but it would take a very long mathematical argument to explain why."
