=The Socializing Process.=--The "socializing" side of the process of development stands for an increased capacity to enter into relations with other human beings. Like the growth of reason it is both a means and an end. It has its roots in certain instincts--sex, gregariousness, parental instincts--and in the necessities of mutual support and protection. But the associations thus formed imply a great variety of activities which call out new powers and set up new ends. Language is one of the first of these activities and a first step toward more complete socialization. Coöperation, in all kinds of enterprises, interchange of services and goods, participation in social arts, associations for various purposes, institutions of blood, family, government, and religion, all add enormously to the individual's power. On the other hand, as he enters into these relations and becomes a "member" of all these bodies he inevitably undergoes a transformation in his interests. Psychologically the process is one of building up a "social" self. Imitation and suggestion, sympathy and affection, common purpose and common interest, are the aids in building such a self. As the various instincts, emotions, and purposes are more definitely organized into such a unit, it becomes possible to set off the interests of others against those interests that center in my more individual good. Conscious egoism and altruism become possible. And in a way that will be explained, the interests of self and others are raised to the plane of rights and justice. =What is Needed to Make Conduct Moral.=--All this is not yet moral progress in the fullest sense. The progress to more rational and more social conduct is the indispensable condition of the moral, but not the whole story. What is needed is that the more rational and social conduct should itself be valued as good, and so be chosen and sought; or in terms of control, that the law which society or reason prescribes should be consciously thought of as right, used as a standard, and respected as binding. This gives the contrast between the higher and lower, as a conscious aim, not merely as a matter of taste. It raises the collision between self and others to the basis of personal rights and justice, of deliberate selfishness or benevolence. Finally it gives the basis for such organization of the social and rational choices that the progress already gained may be permanently secured, while the attention, the struggle between duty and inclination, the conscious choice, move forward to a new issue. Aristotle made these points clear:
