Every character is developed under circumstances, and depends upon mutual adjustment with these; we cannot disentangle the two factors. Upon the power to infer future action the science of Ethics depends. The action of the individual is not a matter of chance; in this sense it is caused. But the instinct from which the action springs is not something external to the man, which moves him; there is not the man plus the instinct; the whole man, including the instinct, acts in a certain way, in which he would not act if he did not possess the instinct. We are accustomed to say that a man has inherited certain qualities; but the man is not one thing and the inherited qualities another; the whole man is inherited. Merit implies effort. This does not mean that effort, taken absolutely, is the measure of merit. Such an assumption would lead to our excusing men for the very qualities that make them wicked,--the murderer because of his spiteful disposition, for instance. The man is most meritorious who is virtuous with the least effort--provided always that he has the normal passions of a man. By these, however, since they are morally neutral, he is accessible to temptation and to a certain struggle. Conscience appears, historically, as a development of simpler instincts; it is not a primary or a separate faculty; material morality makes its appearance long before the conscious recognition of a moral law. The existence of conscience is undeniable. Yet moralists are much given to exaggerate the sorrow which it actually excites. In almost every case, the pain which we feel for a bad act is complex, and due only in part to our conviction that we have broken the moral law. If we regard conscience as a separate faculty judging of action by some inherent power, we have to attribute to it reason and feeling. It is not a primary attribute of the agent (to borrow Spinoza's language), but a mode of the attributes.
