I take it for granted, then, 'that all my readers accept the doctrine of Organic Evolution, or the belief that all species of plants and animals have bad a derivative mode of origin by way of natural descent ; and, moreover, that one great law ormethod of the process has been natural selection, or survival of the fittest. If anyone grants this much, I further assume that he must concede to me the fact, as distinguished from the manner and history of Mental Evolution, throughout the whole range of the animal kingdom, with the exception of man. I assume this because I hold that if the doctrine of Organic Evolution is accepted, it carries with it, as a necessary corollary, the doctrine of Mental Evolution, at all events as far as the brute creation is concerned. For throughout the brute creation, from wholly unintelligent animals to the most highly intelligent, we can trace one continuous gradation ; so that if we already believe that all specific forms of animal life have had a derivative origin, we cannot refuse to believe that all the mental faculties which these various forms present must likewise have had a derivative origin. And, as a matter of fact, we do not find anyone so unreasonable as to maintain, or even to suggest, that if the evidence of Organic Evolution is accepted, the evidence of Mental Evolution, within the limits which I have named, can consistently be rejected. - The one body of evidence therefore serves as a pedestal to the other, such that in the absence of the former the latter would have no locus standi (for no one could well dream, of Mental Evolution were it not for the evidence of Organic Evolution, or of the transmutation of species) ; while the presence of the former irresistibly suggests the necessity of the latter, as the logical structure for the support of which the pedestal is what it is.
お礼
いつも前置詞＋関係代名詞でつまづくんですよ～！ おかげで助かりました。 特に、 take sides ABOUT IT(behavior). の部分は、解りやすかったです。 ありがとうございました。
