  Finally, as Frankena also nicely pointed out, it cannot be assumed at the outset that what Moore calls the naturalistic fallacy really is a mistake of any kind. For certain naturalists could then reasonably complain that the central question has been begged. The naturalist proposes a certain kind of definition of some moral term and the non-naturalist then simply asserts that anyone who thinks such definitions are possible is mistaken. If we want to find a non-question-begging argument against naturalism then we must look beyond the so-called “naturalistic fallacy.”
