 [What] is most properly a man’s self … is … not his passions, but his reason or his judgment, prescribing what is right, and prohibiting what is wrong. The conscience of a man is the man; the reflecting principle is our supreme principle. It is what gives our distinction as intelligent creatures; and whenever we act contrary to it, we violate our natures, and are at variance with ourselves. (Price 1816: 208, quoted in D. O. Thomas 1977: 170)
