“The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back.”—J. M. Keynes, The General Theory of Employment, Interest, and Money (1936).
“In all democratic countries, in the United States even more than elsewhere, a strong belief prevails that the influence of the intellectuals on politics is negligible. This is no doubt true of the power of intellectuals to make their peculiar opinions of the moment influence decisions, of the extent to which they can sway the popular vote on questions on which they differ from the current views of the masses. Yet over somewhat longer periods they have probably never exercised so great an influence as they do today in those countries. This power they wield by shaping public opinion.”—F. A. Hayek, “The Intellectuals and Socialism” (1949).
