Ethical or moral nihilism is the view in meta-ethics that morality does not exist. Moral nihilism holds that there are no moral truths, and that no action can be properly labeled as good or bad, right or wrong.
Moral nihilism is the extreme form of moral skepticism, which denies that objective morality exists. It generally comes in two varieties, one cognitivist and one not:
- Error theory (cognitivist), which holds that moral statements are propositions, but they are all false.
- Non-Cognitivism, which denies that moral statements can be considered true or false, and merely express attitudes or feelings.
