Moral philosophy is the branch of philosophy that contemplates what is right and wrong. It explores the nature of morality and examines how people should live their lives in relation to others.
Moral philosophy has three branches.
One branch, meta-ethics, investigates big picture questions such as, “What is morality?” “What is justice?” “Is there truth?” and “How can I justify my beliefs as better than conflicting beliefs held by others?”
Another branch of moral philosophy is normative ethics. It answers the question of what we ought to do. Normative ethics focuses on providing a framework for deciding what is right and wrong. Three common frameworks are deontology, utilitarianism, and virtue ethics.
The last branch is applied ethics. It addresses specific, practical issues of moral importance such as war and capital punishment. Applied ethics also tackles specific moral challenges that people face daily, such as whether they should lie to help a friend or co-worker.
So, whether our moral focus is big picture questions, a practical framework, or applied to specific dilemmas, moral philosophy can provide the tools we need to examine and live an ethical life.
