The psychologists of the future will therefore have to follow some principle such as this: their only legitimate aim is the maintenance and restoration of harmonious co-ordination of all the human functions, and no concern need be paid to ultimate intellectual or spiritual ideals. Of course if the person considered is apparently tending towards some degenerate condition, that is known to the onlooker because it is _not_ new but a repetition of what many human beings have done before, then this tendency can be altered. At least, it can be altered if the onlooker can use his intuition to discover signs of repressed conflict which show that the immediate tendency is not whole-natured, but based on the repression of some more profound aspiration or desire. Then by bringing this repressed aspiration back into consciousness the degenerate tendency may be arrested. But this control over the lives of others can only be effectively exercised by the intuitive discovery that their present tendencies are not whole-natured. * * * * * Prophecy can never be scientific, and forecasting in the realm of science is perhaps the most dangerous form of intellectual acrobatics. Science must be thorough, and all vague speculation is its enemy. But there are moments when a profound revision is necessary, and amidst the responsibilities and rich appeal of daily life no one will undertake this task who does not believe that it offers an adequate reward to science and to man. To-day prophecy can call attention to unjustified limitations inherent in current scientific thought, and encourage the students of matter and of life to get together and try to discover the single system of natural law which we must believe covers both realms. It may even help them to find crucial experiments by which to guide their search. The reward is certainly great. The indifference to the destruction of life which has marked recent years is no cause either for surprise or for despair after an epoch of orthodox and insincere religion coupled with an abstract science of matter. One thing only can guide humanity to a saner and richer life: the recognition and valuation of life. This can be assisted by science and art both revealing life in all its significant forms. But the roots of art have been destroyed by the domination of a science which had not recognized the significance of life within the realm of natural law. For great art can only arise from a profound reverence for life, whereas to the scientific mood of this period life appeared as an arbitrary impulse in continual conflict with the laws of matter.
