Intelligence becomes ours in the degree in which we use it and accept responsibility for consequences. It is not ours originally or by production. "It thinks" is a truer psychological statement than "I think." Thoughts sprout and vegetate; ideas proliferate. They come from deep unconscious sources. "I think" is a statement about voluntary action. Some suggestion surges from the unknown. Our active body of habits appropriates it. The suggestion then becomes an assertion. It no longer merely comes to us. It is accepted and uttered by us. We act upon it and thereby assume, by implication, its consequences. The stuff of belief and proposition is not originated by us. It comes to us from others, by education, tradition and the suggestion of the environment. Our intelligence is bound up, so far as its materials are concerned, with the community life of which we are a part. We know what it communicates to us, and know according to the habits it forms in us. Science is an affair of civilization not of individual intellect. So with conscience. When a child acts, those about him re-act. They shower encouragement upon him, visit him with approval, or they bestow frowns and rebuke. What others do to us when we act is as natural a consequence of our action as what the fire does to us when we plunge our hands in it. The social environment may be as artificial as you please. But its action in response to ours is natural not artificial. In language and imagination we rehearse the responses of others just as we dramatically enact other consequences. We foreknow how others will act, and the foreknowledge is the beginning of judgment passed on action. We know _with_ them; there is conscience. An assembly is formed within our breast which discusses and appraises proposed and performed acts. The community without becomes a forum and tribunal within, a judgment-seat of charges, assessments and exculpations. Our thoughts of our own actions are saturated with the ideas that others entertain about them, ideas which have been expressed not only in explicit instruction but still more effectively in reaction to our acts.
