Let us then thus consider conscience, not as a rule of right conduct, but as a sanction of right conduct. This is its primary and most authoritative aspect; it is the ordinary sense of the word. Half the world would be puzzled to know what was meant by the moral sense; but every one knows what is meant by a good or bad conscience. Conscience is ever forcing on us by threats and by promises that we must follow the right and avoid the wrong; so far it is one and the same in the mind of every one, whatever be its particular errors in particular minds as to the acts which it orders to be done or to be avoided; and in this respect it corresponds to our perception of the beautiful and deformed. As we have naturally a sense of the beautiful and graceful in nature and art, though tastes proverbially differ, so we have a sense of duty and obligation, whether we all associate it with the same certain actions in particular or not. Here, however, Taste and Conscience part company: for the sense of beautifulness, as indeed the Moral Sense, has no special relations to persons, but contemplates objects in themselves; conscience, on the other hand, is concerned with persons primarily, and with actions mainly as viewed in their doers, or rather with self alone and one’s own actions, and with others only indirectly and as if in association with self. And further, taste is its own evidence, appealing to nothing beyond its own sense of the beautiful or the ugly, and enjoying the specimens of the beautiful simply for their own sake; but conscience does not repose on itself, but vaguely reaches forward to something beyond self, and dimly discerns a sanction higher than self for its decisions, as is evidenced in that keen sense of obligation and responsibility which informs them. And hence it is that we are accustomed to speak of conscience as a voice,—a term which we should never think of applying to the sense of the beautiful; and moreover a voice, or the echo of a voice, imperative and constraining, like no other dictate in the whole of our experience.
