It may be that a free society... carries in itself the forces of its own destruction, that once freedom has been achieved it is taken for granted and ceases to be valued, and that the free growth of ideas which is the essence of a free society will bring about the destruction of the foundations on which it depends.

A claim for equality of material position can be met only by a government with totalitarian powers.

The freedom that will be used by only one man in a million may be more important to society and more beneficial to the majority than any freedom that we all use.

The social sciences, like much of biology but unlike most fields of the physical sciences, have to deal with structures of essential complexity, i.e. with structures whose characteristic properties can be exhibited only by models made up of relatively large numbers of variables.

We must face the fact that the preservation of individual freedom is incompatible with a full satisfaction of our views of distributive justice.

We must make the building of a free society once more an intellectual adventure, a deed of courage. Unless we can make the philosophic foundations of a free society once more a living intellectual issue, and its implementation a task which challenges the ingenuity and imagination of our liveliest minds, the prospects of freedom are indeed dark. But if we can regain that belief in the power of ideas which was the mark of liberalism at its best, the battle is not lost.
