In metaethics, the naturalistic fallacy is the claim that it is possible to define good in terms of merely described entities, properties, or processes such as pleasant, desirable, or fitness.[1] The term was introduced by British philosopher G. E. Moore in his 1903 book Principia Ethica.[2]
Moore's naturalistic fallacy is closely related to the is–ought problem, which comes from David Hume's Treatise of Human Nature (1738–40); however, unlike Hume's view of the is–ought problem, Moore (and other proponents of ethical non-naturalism) did not consider the naturalistic fallacy to be at odds with moral realism.
