"No one sins without making some excuse to himself for sinning. He is obliged to do so: man is not like the brute beasts; he has a divine gift within him which we call reason, and which constrains him to account before its judgment-seat for what he does. He cannot act at random; however he acts, he must act by some kind of rule, on some sort of principle; else he is vexed and dissatisfied with himself.” ~ Cardinal John Henry Newman
