We must shed the illusion that we can deliberately 'create the future of mankind'

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.

We shall not grow wiser before we learn that much that we have done was very foolish.

We shall all be the gainers if we can create a world fit for small states to live in.

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.

To undertake the direction of the economic life of people with widely divergent ideals and values is to assume responsibilities which commit one to the use of force; it is to assume a position where the best intentions cannot prevent one from being forced to act in a way which to some of those affected must appear highly immoral. This is true even if we assume the dominant power to be as idealistic and unselfish as we can possibly conceive. But how small is the likelihood that it will be unselfish, and how great are the temptations!

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.
