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.

No human mind can comprehend all the knowledge which guides the actions of society.

Our freedom of choice in a competitive society rests on the fact that, if one person refuses to satisfy our wishes, we can turn to another. But if we face a monopolist we are at his absolute mercy. And an authority directing the whole economic system of the country would be the most powerful monopolist conceivable…it would have complete power to decide what we are to be given and on what terms. It would not only decide what commodities and services were to be available and in what quantities; it would be able to direct their distributions between persons to any degree it liked.

It is possible for a dictator to govern in a liberal way. And it is also possible for a democracy to govern with a total lack of liberalism. Personally I prefer a liberal dictator to democratic government lacking liberalism.

We shall never prevent the abuse of power if we are not prepared to limit power in a way which occasionally may prevent its use for desirable purposes.

All political theories assume, of course, that most individuals are very ignorant. Those who plead for liberty differ from the rest in that they include among the ignorant themselves as well as the wisest. Compared with the totality of knowledge which is continually utilized in the evolution of a dynamic civilization, the difference between the knowledge that the wisest and that the most ignorant individual can deliberately employ is comparatively insignificant.
