Before Language and After

It has been assumed by some writers that Wittgenstein's talk of primitive reactions amounts to a theory of concept formation out of instinctive behaviour. Others have argued that Wittgenstein is thinking of reactions within language-games, which therefore belong to its structure not its origins . The author concurs, but argues that Wittgenstein also has in mind that it belongs to the grammars of certain concepts that the language-games in which they lie are themselves supplementary to natural behavioural forms. This provides a context in which the notion of pre-linguistic behaviour may be employed legitimately in philosophy whilst avoiding unjustified theorising.
