Moral philosophy
What Is Ethics?
Ethics—or moral philosophy—studies how we ought to act, what makes a life good, and how to evaluate character and institutions.
Short answer
Major approaches include virtue ethics (character), deontology (duty and rights), and consequentialism (outcomes), alongside care ethics and many tradition-specific moral vocabularies.
Three families of theory
Virtue ethics asks what kind of person to become. Deontology asks which rules or rights constrain action. Consequentialism asks which outcomes matter and how to weigh them. Real disputes often mix these lenses.
Applied ethics
Bioethics, AI ethics, environmental ethics, and business ethics apply tools of moral philosophy to concrete dilemmas. Clarity about concepts—harm, consent, fairness—prevents slogan wars.
Ethics beyond the West
Confucian ren, Buddhist compassion, Ubuntu, and Islamic ethics offer structured moral thought that should be read as philosophy, not as exotic decoration on a European map.
