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 is perhaps the most characteristic feature of the intellectual that he judges new ideas not by their specific merits but by the readiness with which they fit into his general conceptions, into the picture of the world which he regards as modern or advanced.
Socialism has never and nowhere been at first a working-class movement. It is by no means an obvious remedy for the obvious evil which the interests of that class will necessarily demand. It is a construction of theorists.
The task of the political philosopher can only be to influence public opinion, not to organize people for action. He will do so effectively only if he is not concerned with what is now politically possible but consistently defends the "general principles which are always the same." In this sense I doubt whether there can be such a thing as a conservative political philosophy. Conservatism may often be a useful practical maxim, but it does not give us any guiding principles which can influence long-range developments.
If I am not mistaken, psychology, psychiatry and some branches of sociology, not to speak about the so-called philosophy of history, are even more affected by what I have called the scientistic prejudice, and by specious claims of what science can achieve.
