1. _The Moral Faculty_. That the conceptions of right and wrong are _sui generis_, is proved (1) by the fact that in all languages there are distinct terms for 'right' and 'agreeable;' (2) by the testimony of consciousness; and (3) by the mutual inconsistencies of the antagonists of a moral sense. The moral faculty is not identical with Reason; for the understanding contributes to truth only one of its elements, namely, the concept; in addition, the concept must agree with the fact as presented in intuition. The moral sense is usually supposed to involve the perception of qualities only in so far as they are _pleasing_ or _displeasing_. To this representation Mr. Mansel objects. In an act of moral consciousness two things are involved: a perception or judgment, and a sentiment or feeling. But the judgment itself may be farther divided into two parts: 'the one, an individual fact, presented now and here; the other, a general law, valid always and everywhere.' This is the distinction between _presentative_ and _representative_ Knowledge. In every act of consciousness there is some individual fact presented, and an operation of the understanding. 'A conscious act of pure moral sense, like a conscious act of pure physical sense, if it ever takes place at all, takes place at a time of which we have no remembrance, and of which we can give no account.' The intuitive element may be called _conscience_; the representing element is the _understanding_. On another point he differs from the ordinary theory. It is commonly said that we immediately perceive the moral character of acts, whether by ourselves or by others. But this would implicate two facts, neither of which we can be conscious of: (1) a law binding on a certain person, and (2) his conduct as agreeing or disagreeing with that law. Now, I can infer the existence of such a law only by _representing_ his mind as constituted like my own. We can, in fact, immediately perceive moral qualities only in our own actions.
