I just added two new quotes to my list of quotes (http://www.externalreflection.com/quotes/):

“It is no crime to be ignorant of economics, which is, after all, a specialized discipline and one that most people consider to be a ‘dismal science.’ But it is totally irresponsible to have a loud and vociferous opinion on economic subjects while remaining in this state of ignorance.” — Murray N. Rothbard

“The probability of the people in power being individuals who would dislike the possession and exercise of power is on a level with the probability that an extremely tender-hearted person would get the job of whipping master in a slave plantation.” — Frank H. Knight (1938), quoted in F. A. Hayek, The Road to Serfdom (Chicago: University of Chicago Press, 1944), p. 152.
