==Feelings from Conscience Perceptions.==
=3.= The existence of the conscience as an integral power of the human constitution is evidenced also by the special feelings which attend its perceptions. They are distinctively peculiar. This is illustrated in the sense of obligation arising from the idea of right and the perception of duty. It is even more clearly illustrated in the satisfaction which attends and follows duty done, and the remorse which follows wrong or crime committed.
The sense of obligation, _i. e._ the emotion awakened by the perception of obligation, is unique among the emotions of the sensibility. In the presence of recognized right or wrong men feel bound to correspondent action as they feel bound under no other perceptions. The conscience, indeed, uses no compulsion, but it presents the right or wrong and correspondent obligation. Freedom is not annulled, but appealed to. The feeling, as the sensibility excited, is the feeling of ought or ought not, added to the perception of it. Nothing like this appears in connection with any of the other perceptions. We may perceive truth, but if the truth is not the particular truth of obligation itself, there is only the pleasure, gratification or admiration in its discovery and attainment. We may perceive beauty, but if the beauty be apart from that of ethical excellence, the feeling is simply æsthetic and different from the obligatory feeling: "I ought." We may perceive utility or understand what is simply profitable, but the feeling awakened is but desire. All these and like simply intellectual perceptions awaken no sense of obligation to cherish any special sentiments or perform any special acts. But as soon as men, in pure and normal state of their rational and emotional nature, perceive the right as over against the wrong, the sensibility which always in greater or less degree responds to every act of knowledge, presents a form of feeling, in the ethical "ought," generically different from the feelings that arise out of all other kinds of knowledge. This feeling is itself a part and parcel of the aggregate or complex of the conscience. But its presence marks the conscience as a special power normally constituent of human nature.
