Conscience is described by such terms as moral approbation and disapprobation; and involves, when highly developed, a peculiar and unmistakeable revulsion of mind at what is wrong, and a strong resentment towards the wrong-doer, which become Remorse, in the case of self. It is capable of being proved, that there is nothing natural or primitive in these feelings, except in so far as the case happens to concur with the dictates of Self-interest, or Sympathy, aided by the Emotions formerly specified. Any action that is hostile to our interest, excites a form of disapprobation, such as belongs to wounded self-interest; and any action that puts another to pain may so affect our natural sympathy as to be disapproved, and resented on that ground. These natural or inborn feelings are always liable to coincide with moral right and wrong, although they are not its criterion or measure in the mind of each individual. But in those cases where an unusually strong feeling of moral disapprobation is awakened, there is apt to be a concurrence of the primitive motives of self, and of fellow-feeling; and it is the ideal of good law, and good morality to coincide with a certain well-proportioned adjustment of the Prudential and the Sympathetic regards of the individual. The requisite allowance being made for the natural impulses, we must now adduce the facts, showing that the characteristic of the Moral Sense is an education under Law, or Authority, through the instrumentality of Punishment. (1) It is a fact that human beings living in society are placed under discipline, accompanied by punishment. Certain actions are forbidden, and the doers of them are subjected to some painful infliction; which is increased in severity if they are persisted in. Now, what would be the natural consequence of such a system, under the known laws of feeling, will, and intellect? Would not an action that always brings down punishment be associated with the pain and the dread of punishment? Such an association is inevitably formed, and becomes at least a part, and a very important part, of the sense of duty; nay, it would of itself, after a certain amount of repetition, be adequate to restrain for ever the performance of the action, thus attaining the end of morality.
