involves a sacrifice of happiness; for the suffering caused by resisting natural tendencies is much greater than would ensue from their moderate gratification. The plain truth is that no proposition can be more palpably and egregiously false than the assertion that as far as this world is concerned, it is invariably conducive to the happiness of a man to pursue the most virtuous career. Circumstances and disposition will make one man find his highest happiness in the happiness, and another man in the misery, of his kind; and if the second man acts according to his interest, the utilitarian, however much he may deplore the result, has no right to blame or condemn the agent. For that agent is following his greatest happiness, and this, in the eyes of utilitarians, in one form or another, is the highest, or to speak more accurately, the only motive by which human nature can be actuated. We may remark too that the disturbance or pain which does undoubtedly usually accompany what is evil, bears no kind of proportion to the enormity of the guilt. An irritability of temper, which is chiefly due to a derangement of the nervous system, or a habit of procrastination or indecision, will often cause more suffering than some of the worst vices that can corrupt the heart.(92) But it may be said this calculation of pains and pleasures is defective through the omission of one element. Although a man who had a very strong natural impulse towards some vice would appear more likely to promote the tranquillity of his nature by a moderate and circumspect gratification of that vice, than by endeavouring painfully to repress his natural tendencies, yet he possesses a conscience which adjudicates upon his conduct, and its sting or its approval constitutes a pain or pleasure so intense, as more than to redress the balance. Now of course, no intuitive moralist will deny, what for a long time his school may be almost said to have been alone in asserting, the reality of conscience, or the pleasures and pains it may afford. He simply denies, and he appeals to consciousness in attestation of his position, that those pains and pleasures are so powerful or so proportioned to our acts as to become an adequate basis for virtue. Conscience, whether we regard it as an original faculty, or as a product of the association of ideas, exercises two distinct functions. It points out a difference between right and wrong, and when its commands are violated, it inflicts a certain measure of suffering and disturbance. The first function it exercises persistently through life. The second it only exercises under certain special circumstances. It is scarcely conceivable that a man in the possession of his faculties should pass a life of gross depravity and crime without being conscious that he was doing wrong; but it is extremely possible for him to do so without this consciousness having any appreciable influence upon his tranquillity. The condition of their consciences, as Mr.
