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!

The importance of our being free to do a particular thing has nothing to do with the question of whether we or the majority are ever likely to make use of that particular possibility. To grant no more freedom than all can exercise would be to misconceive its function completely.

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.
