|We now possess four principles of morality: 1. a philosophical: do good for its own sake, out of respect for the law; 2. a religious: do good because it is God’s will, out of love of God; 3. a human: do good because it will promote your happiness, out of self-love; 4. a political: do good because it will promote the welfare of the society of which you are a part, out of love of society having regard to yourself. But is this not all one single principle, only viewed from different sides?|
