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.

It is also true that the less possible it becomes for a man to acquire a new fortune, the more must the existing fortunes appear as privileges for which there is no justification. Policy is then certain to aim at taking these fortunes out of private hands, either by the slow process of heavy taxation of inheritance or by the quicker one of outright confiscation. A system based on private property and control of the means of production presupposes that such property and control can be acquired by any successful man.

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

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

Socialist thought owes its appeal to the young largely to its visionary character; the very courage to indulge in Utopian thought is in this respect a source of strength for socialism which traditional liberalism sadly lacks. Speculation about general principles provides an opportunity for the play of the imagination of those who are unencumbered by much knowledge of the facts of present-day life. Their ideas suffer from inherent contradictions, and any attempt to put them into practice must produce something utterly different from what they expect.

It seems to be almost a law of human nature that it is easier for people to agree on a negative program - on the hatred of an enemy, on the envy of those better off - than on any positive task.

Civilization enables us constantly to profit from knowledge which we individually do not possess and because each individual's use of his particular knowledge may serve to assist others unknown to him in achieving their ends that men as members of civilized society can pursue their individual ends so much more successfully than they could alone.
