To return to our infant: he is in the midst of a painful process of adjusting himself to the outside world; discovering that sometimes all his magic words and gestures fail, his wishes no longer come true. There are beings outside him, with wills of their own, and power to enforce them; he has to learn to get along with these beings, and give up his pleasures to theirs. These processes which go on in the infant soul, the hopes and the terrors, the griefs and the angers, are of the profoundest significance for the later adult life. For nothing gets out of the mind that has once got into it; the infantile cravings which are repressed and forgotten stay in the unconscious, and work there, and strive still for expression. The conscious mind will not tolerate them, but they escape in the form of fairy-tales and stories, of dreams and delusions, slips of the tongue, and many other mental events which it is fascinating to examine. Also, if we are weakened by ill health or nervous strain, these infantile wishes may take the form of "neuroses," and fully grown people may take to stammering, or become impotent, or hysterical, or even insane, because of failures of adjustment to life that happened when they were a year or two old. These things are known, not merely as a matter of theory, but because, as soon as by analysis these infant secrets are brought into consciousness and adjusted there, the trouble instantly ceases. So it appears that the whole process of human life, from the very hour of birth, consists of the correct adjustment of men and women in relation to their fellows. Not merely is man a social being, but all the prehuman ancestors of men, for ages upon geologic ages, have been social beings; they have lived in groups, and their survival has depended upon their success in fitting themselves snugly into group relationships. Failure to make correct adjustments means punishment by the group, or by enemies outside the group; if the failure is serious enough, it means death. We may assert that the task of understanding one's fellow men, and making one's self understood by them, is the most important task that confronts every individual.
