The confidence in the unlimited power of science is only too often based on a false belief that the scientific method consists in the application of a ready-made technique, or in imitating the form rather than the substance of scientific procedure, as if one needed only to follow some cooking recipes to solve all social problems. It sometimes almost seems as if the techniques of science were more easily learnt than the thinking that shows us what the problems are and how to approach them.

The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design.

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 conservatives have already accepted a large part of the collectivist creed-a creed that has governed policy for so long that many of its institutions have come to be accepted as a matter of course and have become a source of pride to "conservative" parties who created them. Here the believer in freedom cannot but conflict with the conservative and take an essentially radical position, directed against popular prejudices, entrenched positions, and firmly established privileges. Follies and abuses are no better for having long been established principles of folly.

We know, in other words, the general conditions in which what we call, somewhat misleadingly, an equilibrium will establish itself: but we never know what the particular prices or wages are which would exist if the market were to bring about such an equilibrium.

Economic control is not merely control of a sector of human life which can be separated from the rest; it is the control of the means for all our ends. And whoever has sole control of the means must also determine which ends are to be served, which values are to be rates higher and which lower, in short, what men should believe and strive for.

The progress of the natural sciences in modern times has of course so much exceeded all expectations that any suggestion that there may be some limits to it is bound to arouse suspicion.
