Anselm's view of sin

Suppose you were to find yourself in the presence of God and someone were to give you the command: "Look in that direction." And suppose that, on the contrary, God were to say: "I am absolutely unwilling for you to look." Ask yourself in your heart what there is, among all existing things, for the sake of which you ought to take that look in violation of God's will.

Saint Anselm of Canterbury, Cur Deus Homo
