Conscience is the voice of the soul, the passions are the voice of the body. Is it astonishing that often these two languages contradict each other, and then to which must we listen? Too often reason deceives us; we have only too much acquired the right of refusing to listen to it; but conscience never deceives us; it is the true guide of man; it is to man what instinct is to the body; which follows it, obeys nature, and never is afraid of going astray.
