conscience con·science (kŏn’shəns)
n.

The awareness of a moral or ethical aspect to one’s conduct together with the urge to prefer right over wrong.

The part of the superego that judges the ethical nature of one’s actions and thoughts and then transmits such determinations to the ego for consideration.

that faculty of the mind, or inborn sense of right and wrong, by which we judge of the moral character of human conduct. It is common to all men. Like all our other faculties, it has been perverted by the Fall (John 16:2; Acts 26:9; Rom. 2:15). It is spoken of as “defiled” (Titus 1:15), and “seared” (1 Tim. 4:2). A “conscience void of offence” is to be sought and cultivated (Acts 24:16; Rom. 9:1; 2 Cor. 1:12; 1 Tim. 1:5, 19; 1 Pet. 3:21).
