O Conscience! Conscience! thou divine instinct, thou certain guide of an ignorant and confined, though intelligent and free being;—thou infallible judge of good and evil, who makest man to resemble the Deity. In thee consist the excellence of our nature and the morality of our actions. Without thee I perceive nothing in myself that should elevate me above the brutes, except the melancholy privilege of wandering from error to error by the assistance of an ill-regulated understanding and undisciplined reason.
