Why Morality Is Not Just Rules
Metaethics does not tell you what is right or wrong. Instead, it asks whether goodness even exists as a fact or if it is merely a human invention.
While normative ethics focuses on deciding how we should live, metaethics steps back to investigate the very language of morality. Philosophers explore if moral truths are universal or if they depend entirely on cultural perspective. It is essentially the study of where our conscience actually comes from. This deep inquiry forces us to consider if our values are discovered in the universe or crafted by our own minds.
