Machines deprive us of two things which are certainly important ingredients of human happiness, namely, spontaneity and variety. - Bertrand Russell

I know that most people meet such considerations with a kind of facile optimism; they say "Oh, the men of science are sure to think of some clever invention, and even if they don't it will last my time." They feel like the proverbial Irishman — "Why should I do anything for posterity; it never did anything for me!" But I am concerned in this book with Man, considered as a single creature with a single biography. I cannot be content with a brief moment of riotous living followed by destitution, and however clever the scientists may be, there are some things that they cannot be expected to achieve. When they have used up all the easily available sources of energy that nature has scattered carelessly over the surface of our planet, they will have to resort to more laborious processes, and these will involve a gradual lowering of the standard of living. Modern industrialists are like men who have come for the first time upon fertile virgin land, and can live for a little while in great comfort with only a modicum of labor. It would be irrational to hope that the present heyday of industrialism will not develop far beyond its present level, but sooner or later, owing to the exhaustion of raw material, its capacity to supply human needs will diminish, not suddenly, but gradually. This could, of course, be prevented if men exercised any restraint or foresight in their present frenzied exploitation. Perhaps before it is too late they will learn to do so. But this is a question of politics, and I do not wish, as yet, to consider the political aspect of our problem.

Philosophy, from the earliest times, has made greater claims, and achieved fewer results, than any other branch of learning.

Those who have been inspired to action by the doctrine of the class war will have acquired the habit of hatred, and will instinctively seek new enemies when the old ones have been vanquished. But in actual fact the psychology of the working man in any of the Western democracies is totally unlike that which is assumed in the Communist Manifesto. He does not by any means feel that he has nothing to lose but his chains, nor indeed is this true. The chains which bind Asia and Africa in subjection to Europe are partly riveted by him. He is himself part of a great system of tyranny and exploitation. Universal freedom would remove, not only his own chains, which are comparatively light, but the far heavier chains which he has helped to fasten upon the subject races of the world.
