Final remarks

With these sketches of how Wittgensteinian ideas might be brought to bear on the challenge posed for those who posit external reasons and motives by naturalist proponents of the ‘extreme’ version of Hume’s practicality argument, I reach the end of my inquiry. The case for non-cognitivism is, I have argued, fundamentally flawed in so far as it is made through the ‘moderate’ version of Hume’s argument, whose precarious validity depends on its never being fully distinguished from the valid ‘extreme’ version. The cognitivist/non-cognitivist opposition itself gives way, once we unambiguously focus on the ‘extreme’ version of the practicality argument, to the opposition between naturalists, whether cognitivist or non-cognitivist, and nonnaturalists.
