Philosophy Metaethics Questions
The naturalistic fallacy is a philosophical error that occurs when one attempts to derive moral or evaluative statements from purely descriptive or factual statements about the natural world. It is the mistaken belief that what is natural or how things are in nature determines what is morally right or wrong. This fallacy was famously identified by philosopher G.E. Moore in his book "Principia Ethica" in 1903. According to Moore, moral properties are fundamentally different from natural properties, and it is incorrect to equate or derive one from the other.
