An appeal to nature is an argument or rhetorical tactic in which it is proposed that "a thing is good ''because'' it is 'natural', or bad ''because'' it is 'unnatural'".〔Moore, George E.: ''Principia Ethica'', Barnes and Noble Publishing, Inc (1903, 2005) p. 47〕 == Forms == General form of this type of argument:〔 : : : : In some contexts, the use of the terms of "nature" and "natural" can be vague, leading to unintended associations with other concepts. The word "natural" can also be a loaded term – much like the word "normal", in some contexts, it can carry an implicit value judgement. An appeal to nature would thus beg the question, because the conclusion is entailed by the premise.〔 Opinions differ regarding appeal to nature in rational argument. Sometimes, it can be taken as a rule of thumb that admits some exceptions, but nonetheless proves to be of use in one or more specific topics, (or in general). As a rule of thumb, natural or unnatural facts provide presumptively reliable good or bad values, ''barring evidence to the contrary.'' Failure to consider such evidence commits a fallacy of accident under this view. Julian Baggini explains that "Even if we can agree that some things are natural and some are not, what follows from this? The answer is: nothing. There is no factual reason to suppose that what is natural is good (or at least better) and what is unnatural is bad (or at least worse)." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「appeal to nature」の詳細全文を読む スポンサード リンク
