 This argument is wheeled on to discredit a particular naturalistic analysis of “good”—“one of the more plausible, because one of the more complicated of such definitions”—that “ good mean[s] … that which we desire to desire”. Where did Moore get this definition? He does not say, crediting it, in effect, to Mr Nobody. But in fact the inventor of this plausible but fallacious definition was none other than the Hon. Bertrand Russell.
