Is Morality Natural or Supernatural?

The author argues that morality is best understood as a natural human system rather than a supernatural one. By comparing moral rules with traffic regulations, it shows that features often deemed metaphysically puzzling—normativity, fact dependence, categorical force, universality and virtue—arise naturally from the practical need to coordinate behaviour for mutual benefit. Morality, like traffic control, forms an integrated system of aims, rules, roles, virtues and sanctions. Recognizing its natural origins dissolves the need for supernatural grounding and clarifies why moral norms carry authority within human communities.
