Moral realism is a philosophical viewpoint that asserts the existence of objective moral facts. According to this perspective, certain actions are inherently right or wrong, independent of individual beliefs or cultural norms. This means that moral statements can be true or false based on these objective standards. Proponents of moral realism argue that moral truths can be discovered through reason, experience, or observation, similar to scientific truths. This contrasts with moral anti-realism, which suggests that moral values are subjective and vary from person to person or culture to culture. Key figures in this debate include philosophers like David Brink and Peter Railton.
