Moral growth from the first on through the second stage may be described as a process in which man becomes more _rational_, more _social_, and finally more _moral_. We examine briefly each of these aspects. =The Rationalizing or Idealizing Process.=--The first need of the organism is to live and grow. The first instincts and impulses are therefore for food, self-defence, and other immediate necessities. Primitive men eat, sleep, fight, build shelters, and give food and protection to their offspring. The "rationalizing" process will mean at first greater use of intelligence to satisfy these same wants. It will show itself in skilled occupations, in industry and trade, in the utilizing of all resources to further man's power and happiness. But to rationalize conduct is also to introduce new ends. It not only enables man to get what he wants; it changes the kind of objects that he wants. This shows itself externally in what man makes and in how he occupies himself. He must of course have food and shelter. But he makes temples and statues and poems. He makes myths and theories of the world. He carries on great enterprises in commerce or government, not so much to gratify desires for bodily wants as to experience the growth of power. He creates a family life which is raised to a higher level by art and religion. He does not live by bread only, but builds up gradually a life of reason. Psychologically this means that whereas at the beginning we want what our body calls for, we soon come to want things which the mind takes an interest in. As we form by memory, imagination, and reason a more continuous, permanent, highly-organized self, we require a far more permanent and ideal kind of good to satisfy us. This gives rise to the contrast between the material and ideal selves, or in another form, between "the world" and "the spirit."
