The document discusses the relationship between self-interest and morality. It explores the views of philosophers such as Machiavelli, who believed politically enlightened self-interest could lead to a stable society, and Adam Smith, who thought a perfect society allowed people to freely pursue self-interest. While self-interest seems opposed to morality, some argue enlightened self-interest or altruism can help people act morally. The document also examines the views of moral authorities like Bentham, Mill, and Kant on how to determine right and wrong, as well as the role of religion, work, and moral relativism in questions of morality.
