Nothing is more humane than psychology, in the long run, even though the psychologist may seem unfeeling in the course of his investigation.

To the psychologist, conduct is a matter of cause and effect, of natural law. His business is to know the laws of that part of nature which we call human nature, and to use these laws, as fast as discovered, for solving the problems presented by the human individual or group. For him, even the most capricious conduct has its causes, even the most inexplicable has its explanation--if only the cause can be unearthed, which he does not pretend he can always actually accomplish, since causes in the mental realm are often very complex.

No one can be a psychologist all of the time; no one can or should always maintain this matter-of-fact att.i.tude towards self and neighbor. But some experience with the psychological att.i.tude is of practical value to any one, in giving clearer insight, more toleration, better control, and even saner standards of living.
