It used to be the boast of free men that, so long as they kept within the bounds of the known law, there was no need to ask anybody's permission or to obey anybody's orders. It is doubtful whether any of us can make this claim today.

The Socratic maxim that the recognition of our ignorance is the beginning of wisdom has profound significance for our understanding of society. Most of the advantages of social life, especially in the more advanced forms that we call "civilization" rest on the fact that the individual benefits from more knowledge than he is aware of. It might be said that civilization begins when the individual in the pursuit of his ends can make use of more knowledge than he has himself acquired and when he can transcend the boundaries of his ignorance by profiting from knowledge he does not himself possess.

[Socialistic] economic planning, regulation, and intervention pave the way to totalitarianism by building a power structure that will inevitably be seized by the most power-hungry and unscrupulous.

It can hardly be denied that such a demand quite arbitrarily limits the facts which are to be admitted as possible causes of the events which occur in the real world.

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.

If we were to make no better use of victory than to countenance existing trends in this direction, only too visible before 1939, we might indeed find that we have defeated National Socialism merely to create a world of many national socialisms, differing in detail, but all equally totalitarian, nationalistic, and in recurrent conflict with each other.

You can have economic freedom without political freedom, but you cannot have political freedom without economic freedom.
