We have seen that the development of the intellect as it appears in the growing distinctness of self-consciousness exercises an important influence on the development of the moral faculty. But there is still another way in which this influence becomes apparent. The function of conscience further depends on the power of keeping alternative courses of action before the mind. Angels capable only of the good, or fiends actuated exclusively by malice, could not be called moral creatures. A moral act always presupposes a previous choice between two possible lines of action. And until the power of holding the judgment in suspense, of hesitating between alternative lines of conduct, has been acquired, conscience, strictly speaking, does not manifest itself. We may say that the voice of conscience begins to be heard when, the parent being absent, the child hesitates between a forbidden pleasure and obedience to the parental command. Of course, not every choice between alternative courses is a moral act. If any one hesitates whether to remain at home or to go for a walk, whether to take a road to the right or to the left, the decision is morally indifferent. But whenever one of the alternative courses is good and the other bad, conscience does come into play.
