Daniel Dennett on Morality without God
Dennett argued that morality is a product of evolution and culture, fully explicable without divine foundations.
Dennett's case for morality without God was built on his broader project of naturalising the mind. In Freedom Evolves and Darwin's Dangerous Idea, he argued that moral behaviour — cooperation, empathy, fairness, punishment of cheaters — evolved through natural selection in social species. These traits are observable in primates, elephants, and other social animals, long before any concept of God enters the picture.
He went further than most evolutionary ethicists by arguing that cultural evolution builds on biological evolution to produce increasingly sophisticated moral frameworks. The expansion of the circle of moral concern — from kin to tribe to nation to species — is a real and documentable phenomenon, driven by reason, trade, communication, and the gradual recognition of shared humanity. This progress requires no divine input.
Against the claim that without God, morality is 'merely subjective,' Dennett argued that moral facts are objective in the same way that facts about health are objective. There are things that genuinely promote human flourishing and things that genuinely undermine it, and these truths hold regardless of anyone's beliefs about God. The objectivity of morality no more requires a divine legislator than the objectivity of medicine requires one.
“The idea that we need God to be good is not just wrong — it is insulting. It implies that without divine surveillance, we would all be monsters.”
