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.

It is perhaps the most characteristic feature of the intellectual that he judges new ideas not by their specific merits but by the readiness with which they fit into his general conceptions, into the picture of the world which he regards as modern or advanced.

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.

Even when men approve of the same arrangements, it must be asked whether they approve of them because they exist or because they are desirable in themselves. The common resistance to the collectivist tide should not be allowed to obscure the fact that the belief in integral freedom is based on an essentially forward-looking attitude and not on any nostalgic longing for the past or a romantic admiration for what has been.

By the age of fifteen, I had convinced myself that nobody could give a reasonable explanation of what he meant by the word 'God' and that it was therefore as meaningless to assert a belief as to assert a disbelief in God. Though this, in a general way, has remained my position ever since, I have always avoided unnecessarily to offend other people holding religious belief by displaying my lack of such belief, or even stating my lack of belief, if I was not challenged.

Capitalism is not only a better form of organizing human activity than any deliberate design, any attempt to organize it to satisfy particular preferences, to aim at what people regard as beautiful or pleasant order, but it is also the indispensable condition for just keeping that population alive which exists already in the world. I regard the preservation of what is known as the capitalist system, of the system of free markets and the private ownership of the means of production, as an essential condition of the very survival of mankind.

This means that to entrust to science - or to deliberate control according to scientific principles - more than scientific method can achieve may have deplorable effects.
