If we have, however, among this group “like-response,” that is if there spring up like thoughts and feelings, we find a more dignified and worthy life—fellowship claims us with all its joys and its enlargement of our single self. But there is no progress here. We give ourselves up to the passive enjoyment of that already existing. We have found our kindred and it comforts us. How much greater enhancement comes from that life foreshadowed by the new psychology where each one is to go forth from his group a richer being because each one has taken and put into its right membership all the vital differences of all the others. The like-mindedness which the new psychology demands is the like-mindedness which is brought about by the enlargement of each by the inflowing of every other one. Then I go forth a new creature. But to what do I go forth? Always to a new group, a new “society.” There is no end to this process. A new being springs forth from every fresh contact. My nature opens and opens to thousands of new influences. I feel countless new births. Such is the glory of our common every-day life. Imitation is for the shirkers, like-mindedness for the comfort lovers, unifying for the creators. The lesson of the new psychology is then: Never settle down within the theory you have chosen, the cause you have embraced; know that another theory, another cause exists, and seek that. The enhancement of life is not for the comfort-lover. As soon as you succeed—real success means something arising to overthrow your security. In all the discussion of “similarity” too much importance has been put upon analogies from the animal world.[13] We are told, for instance, and important conclusions are drawn in regard to human society, that the gregarious instinct of any animal receives satisfaction only through the presence of animals similar to itself, and that the closer the similarity the greater the satisfaction. True certainly for animals, but it is this fact which keeps them mere animals. As far as the irrational elements of life give way to the rational, interpenetration becomes the law of association. Man’s biological inheritance is not his only life. And the progress of man means that this inheritance shall occupy a less and less important place relatively.
