To act on the belief that we possess the knowledge and the power which enable us to shape the processes of society entirely to our liking, knowledge which in fact we do not possess, is likely to make us do much harm.

I have come to feel strongly that the greatest service I can still render to my fellow men would be that I could make the speakers and writers among them thoroughly ashamed ever again to employ the term "social justice.

Justice, like liberty and coercion, is a concept which, for the sake of clarity, ought to be confined to the deliberate treatment of men by other men.

In government, the scum rises to the top.

We know: of course, with regard to the market and similar social structures, a great many facts which we cannot measure and on which indeed we have only some very imprecise and general information.

The mind cannot foresee its own advance.

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.
