Ethical Egoism – A normative ethical theory that argues individuals should act in their own self-interest and that this is morally right.
Aquinas' Theory of Natural Law – Thomas Aquinas’ theory states that moral laws are based on human nature and reason, and they are derived from a divine order. It suggests that good is to be done and pursued while evil is to be avoided.
Divine Command Theory – The view that morality is determined by God’s commands. Actions are right or wrong based on whether they align with divine will.
Social Contract Theory – The idea that moral and political obligations arise from an implicit contract among individuals to form a society. Thinkers like Hobbes, Locke, and Rousseau contributed to this theory.
Classical Virtue Ethics – Originating with Aristotle, this theory emphasizes developing virtuous character traits (e.g., courage, temperance) as the key to moral living rather than following rigid rules.
Virtue-Based Theories – Ethical theories that emphasize moral character and virtues rather than rules or consequences. Focuses on being a good person rather than merely doing good acts.
Natural Law Theories – Philosophical theories suggesting that moral principles are inherent in nature and can be discovered through reason. They often align with religious perspectives but can also have secular interpretations.
Human Moral Sentimentalism – A theory that suggests moral judgments are based on human emotions and sentiments rather than reason alone. Thinkers like David Hume have contributed to this perspective.
Deontology – A moral theory associated with Immanuel Kant that emphasizes duty and rules. Actions are morally right if they follow a universal moral law, regardless of consequences.
Utilitarianism – A form of consequentialism that holds that the right action is the one that maximizes overall happiness or pleasure while minimizing pain. Jeremy Bentham and John Stuart Mill are key figures in this theory.
Consequentialism – A broader ethical theory that determines the morality of an action based on its consequences. Utilitarianism is a specific form of consequentialism.
