The naturalistic fallacy is a philosophical concept that occurs when someone attempts to derive moral conclusions from purely factual statements about nature. For example, claiming that something is "good" simply because it is "natural" is a common form of this fallacy. This reasoning overlooks the distinction between what is and what ought to be, leading to flawed ethical arguments. This fallacy is often discussed in the context of ethics and morality, particularly in debates surrounding topics like environmentalism and health. It highlights the importance of not conflating descriptive statements about the world with prescriptive moral judgments, reminding us that ethical values cannot be solely based on natural occurrences.
