There are three ideas connected in our mind with conscience, which we must look at if we would not have confusion in our minds. Firstly, the sense of responsibility to a Being above us, principally to God; not the duty of loving Him (that is law), but authority. Adam had this before the fall. Secondly, the sense of good and evil. Thirdly, the self-judgment or repulsion of heart (as to others) produced by this sense of good and evil, when an act is contemplated it condemns. As I understand it, the second is properly called conscience.
