  Once again, however, the scope of the argument is not as great as Moore supposed. For anti-reductionist forms of naturalism (like Sturgeon’s) seem as invulnerable to the argument as Moore’s non-naturalist account. Still, if the argument were to defeat all reductionist forms of naturalism that would be of substantial interest and might well be part of larger argument for non-naturalism when combined with an independent argument against anti-reductionist forms of naturalism (for further discussion, see Ball 1988, Ball 1991 and Baldwin 1990: 87–89).
