In no other field has the world yet paid so dearly for the abandonment of nineteenth-century liberalism as in the field where the retreat began: in international relations. Yet only a small part of the lesson which experience ought to have taught us has been learned.

The moral consequences of totalitarian propaganda...are destructive of all morals because they undermind one of the foundations of all morals: the sense of and respect for truth.

To rest the case for equal treatment of national or racial minorities on the assumption that they do not differ from other men is implicitly to admit that factual inequality would justify unequal treatment, and the proof that some differences do, in fact, exist would not be long in forthcoming. It is of the essence of the demand for equality before the law that people should be treated alike in spite of the fact that they are different.

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.

The ultimate decision about what is accepted as right and wrong will be made not by individual human wisdom but by the disappearance of the groups that have adhered to the "wrong" beliefs.

What our generation has forgotten is that the system of private property is the most important guarantee of freedom, not only for those who own property, but scarcely less for those who do not. It is only because the control of the means of production is divided among many people acting independently that nobody has complete power over us, that we as individuals can decide what to do with ourselves.

While an equality of rights under a limited government is possible and an essential condition of individual freedom, a claim for equality of material position can be met only by a government with totalitarian powers.
