reconstruction, it is necessary to realize what are the vital needs of ordinary men and women. It is customary, in political thought, to assume that the only needs with which politics is concerned are economic needs. This view is quite inadequate to account for such an event as the present war, since any economic motives that may be assigned for it are to a great extent mythical, and its true causes must be sought for outside the economic sphere. Needs which are normally satisfied without conscious effort remain unrecognized, and this results in a working theory of human needs which is far too simple. Owing chiefly to industrialism, many needs which were formerly satisfied without effort now remain unsatisfied in most men and women. But the old unduly simple theory of human needs survives, making men overlook the source of the new lack of satisfaction, and invent quite false theories as to why they are dissatisfied. Socialism as a panacea seems to me to be mistaken in this way, since it is too ready to suppose that better economic conditions will of themselves make men happy. It is not only more material goods that men need, but more freedom, more self-direction, more outlet for creativeness, more opportunity for the joy of life, more voluntary coöperation, and less involuntary subservience to purposes not their own. All these things the institutions of the future must help to produce, if our increase of knowledge and power over Nature is to bear its full fruit in bringing about a good life.
