Meta-ethics is a branch of philosophy that explores the nature, origins, and meaning of ethical concepts. It seeks to answer questions like "What does 'good' really mean?" and "Are moral values universal or subjective?" By examining the foundations of morality, meta-ethics helps clarify how we understand right and wrong. This field contrasts with normative ethics, which focuses on what actions are morally right or wrong. Meta-ethics also investigates the implications of moral language and whether moral statements can be true or false, engaging with ideas from philosophers like David Hume and Immanuel Kant.
