Language and Prescription

'Following a Rule' is not a topic that just happens to appear in the course of the Investigations.  It is an implicit theme from the outset, an ingredient in his concept of a Language-Game, e. g. in the use of Language by two builders.  It also exemplifies the distinctiveness of this work in the history of Philosophy of Language, and why the Investigations is more than just a heterodox approach to the same subject matter that Frege, Russell, etc. study.  Rather, it is the subject matter itself that is different.  Of course, the matter is still Language, but it is Language of an objectively different kind than that of the orthodoxy--Prescriptive Language, rather than Descriptive Language.  And, it is this distinction that is the basis of the classification of the work as 'Pragmatist'.  But, whether or not Wittgenstein prefers it as such, the concept of Prescription also entails that of Psychology, i. e. Language that is acted upon, which is why 'enacting a rule' is more accurate than 'following a rule', as has been previously discussed.  And, whether or not he recognizes it as such, the ancestor of the concept of Language as Prescriptive is not Frege, but Kant, i. e. his concept of Imperative.  So, within Philosophy of Language, Wittgenstein's digression of greater scope is reduced to an alternative concept of Semantics, defended and adopted by some, resisted by others.
