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.

Never will man penetrate deeper into error than when he is continuing on a road which has led him to great success

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.

Democracy is essentially a means, a utilitarian device for safeguarding internal peace and individual freedom. As such it is by no means infallible or certain.
