Moral Naturalism as a Response to Evolutionary Debunking Arguments

Evolutionary Debunking Arguments (EDAs) against morality attempt to show that our moral beliefs are unjustified. However, justification can be restored if we can provide a compelling moral naturalist account, an account that identifies the moral facts with some set of natural facts. Two major proponents of EDAs against morality provide arguments that attempt to show that such a compelling naturalist theory is not existent and likely never will be. This thesis argues that moral naturalist theories that meet certain reasonable constraints can avoid the force of these challenges, and thus meet the challenge posed by the EDA.
