Moral nihilism (also called ethical nihilism) is the meta-ethical view that nothing is morally right or morally wrong and that morality does not exist.^[1][2]

Moral nihilism is distinct from moral relativism, which allows for actions to be wrong relative to a particular culture or individual. It is also distinct from expressivism, according to which when we make moral claims, "We are not making an effort to describe the way the world is ... we are venting our emotions, commanding others to act in certain ways, or revealing a plan of action".^[3]

holding nihilism does not necessarily imply that one should give up using moral or ethical language; some nihilists contend that it remains a useful tool.^[4] In fact Mackie and other contemporary defenders of Error Theory, such as Richard Joyce, defend the use of moral or ethical talk and action even in knowledge of their fundamental falsity. The legitimacy of this activity is a subject of debate in philosophy.
