Freedom granted only when it is known beforehand that its effects will be beneficial is not freedom.

We must shed the illusion that we can deliberately "create the future of mankind." This is the final conclusion of the forty years which I have now devoted to the study of these problems

The problems raised by a conscious direction of economic affairs on a national scale inevitably assume even greater dimensions when the same is attempted internationally. The conflict between planning and freedom cannot but become more serious as the similarity of standards and values among those submitted to a unitary plan diminishes.

From the fact that people are very different it follows that, if we treat them equally, the result must be inequality in their actual position, and that the only way to place them in an equal position would be to treat them differently. Equality before the law and material equality are therefore not only different but are in conflict with each other; and we can achieve either one or the other, but not both at the same time.

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.

We must raise and train an army of fighters for freedom.

It is only because the majority opinion will always be opposed by some that our knowledge and understanding progress. In the process by which opinion is formed, it is very probable that, by the time any view becomes a majority view, it is no longer the best view: somebody will already have advanced beyond the point which the majority have reached. It is because we do not yet know which of the many competing new opinions will prove itself the best that we wait until it has gained sufficient support.
