Nor is it true that self-interest generally is enlightened; more often individuals acting separately to promote their own ends are too ignorant or too weak to attain even these.

My feelings about Das Kapital are the same as my feelings about the Koran. I know that it is historically important and I know that many people, not all of whom are idiots, find it a sort of Rock of Ages and containing inspiration. Yet when I look into it, it is to me inexplicable that it can have this effect. Its dreary, out-of-date, academic controversialising seems so extraordinarily unsuitable as material for the purpose … How could either of these books carry fire and sword round half the world? It beats me. [writing to George Bernard Shaw]

Like the monetarist Milton Friedman, Keynes looked to price stability as a way to shore up classical economic thinking. For the most part, he believed, laissez-faire economics worked. Supply and demand did bring society to a prosperous equilibrium. They just needed a few pieces of basic economic architecture to work: property rights, the rule of law, and price stability. But unlike Friedman, Keynes had arrived at monetarism as a creative way to expand the power of the state to fight the uncertainties and anxieties of postwar life.
