Abstract

The later Wittgenstein claimed to resolve philosophical problems through returning words to their 'ordinary' use. The paradox arises that Wittgenstein's own philosophy must be written in a philosophical language and, therefore, in an extra-ordinary language. The paradox is discussed with particular reference to rules. Rules constitute language, but the account of the 'rule' itself leads to paradox and contradiction. A rule is followed and following a rule requires an interpretation. The interpretation of the rule requires a decision. The decision precedes the rule, so it justifies following a rule but there cannot be a rule for the decision itself
