This document presents an overview of several theories of ethics, including Kant's approach, utilitarianism, religious ethics, and duty ethics. It introduces Kant's nonconsequentialist view that the moral worth of an action depends on its intrinsic features rather than results. Utilitarianism is described as holding that actions should produce the most pleasure for the greatest number of people. Religious ethics are defined as authoritative rule books that differ across cultures. Duty ethics maintain that fulfilling obligations and duties is important.
