It looked earlier as if everyone had to be a realist about something (Chapter 3, section 10). At that point I was using the word ‘realism’ for any view opposed to true-for-me relativism. Normally it is applied to more interesting views. In this chapter, having noted some of the main positions typically describable as ‘realist’ and ‘anti-realist’, I will examine an argument for a variety of anti-realism which exploits Wittgenstein’s idea of language-games – though not, I think, in a way he would have endorsed. The argument is seductive, and seems actually to have convinced a lot of people. However, it is not compelling.
