Ever since the beginning of modern science, the best minds have recognized that "the range of acknowledged ignorance will grow with the advance of science." Unfortunately, the popular effect of this scientific advance has been a belief, seemingly shared by many scientists, that the range of our ignorance is steadily diminishing and that we can therefore aim at more comprehensive and deliberate control of all human activities. It is for this reason that those intoxicated by the advance of knowledge so often become the enemies of freedom.

Any man who is only an economist is unlikely to be a good one.

The attitude of the liberal towards society is like that of the gardener who tends a plant and, in order to create the conditions most favorable to its growth, must know as much as possible about its structure and the way it functions.

I regard it in fact as the great advantage of the mathematical technique that it allows us to describe, by means of algebraic equations, the general character of a pattern even where we are ignorant of the numerical values which will determine its particular manifestation.

[Socialistic] economic planning, regulation, and intervention pave the way to totalitarianism by building a power structure that will inevitably be seized by the most power-hungry and unscrupulous.

Fascism is the stage reached after communism has proved an illusion.

Though freedom and wealth are both good things which most of us desire and though we often need both to obtain what we wish, they still remain different. Whether or not I am my own master and can follow my own choice and whether the possibilities from which I must choose are many or few are two entirely different questions. The courtier living in the lap of luxury but at the beck and call of his prince may be much less free than a poor peasant or artisan, less able to live his own life and to choose his own opportunities for usefulness.
