Naturalistic Fallacy
Logical fallacyIn G. E. Moore's original sense, defining 'good' as identical to some natural property (pleasant, natural, evolved) so that the moral question is settled by definition. Frequently confused with the is–ought fallacy; they are related but distinct. This one is an error about definition, is–ought is an error about inference.
An everyday example
“'Good' simply means 'whatever increases pleasure', so by definition nothing pleasurable can be wrong.”
The same move in this debate
“'Good' just means 'natural', so eating meat is good by definition.”
