Reject the appeal-to-nature fallacy

HL only

Reject the appeal-to-nature fallacy.

The appeal-to-nature fallacy treats whatever is natural as automatically good or morally right.

A disease is natural but harmful; a synthetic water filter may protect health better than a natural contaminant-removal process.

Evaluate consequences, rights and evidence rather than the origin label.

Key idea: Reject the appeal-to-nature fallacy.

Natural and good are different categories.
