The appeal to nature is fallacious for two reasons. First, it is not always clear what is "natural" or "unnatural." The idea that it is natural for all individuals to reproduce is falsified by the existence of eusocial insects. Second, even if something is clearly established to be natural or unnatural, that does not by itself demonstrate that the thing is good or bad. Many things occurring in nature are poisonous. | The appeal to nature is fallacious for two reasons. First, it is not always clear what is "natural" or "unnatural."
