In recent times Wittgenstein's work in logic has had an influence on other branches of philosophy. I am thinking, in particular, of social philosophy and the philosophy of religion. In these branches, Wittgenstein's followers have made much use of his notion of a language game. It has been argued, for example, that religion forms a language game of its own, having its own standards of reason, and is therefore not subject to criticism from outside. This argument has given rise to controversy, some seeing it as a subtle attempt by the religious to evade criticism. I have come myself to feel that the notion of a language game has been put to uses with which Wittgenstein himself might not have agreed, or, if he had, would have been wrong to do so. In order to explain what I mean I should like to look closely at the opening section of Peter Winch's article ‘Understanding a Primitive Society’.
