In my brief contribution to this discussion, I want to suggest that an understanding of Wittgenstein’s later philosophy, and the recognition of its striking differences from any previous philosophical works, can make some important contributions to all the issues mentioned above. I hope its brevity will not detract from its usefulness.
Let me begin by noting, that while Wittgenstein is not critical of scientific investigations as such (in their own proper context), the whole scientific approach is in fact inimical to the character of his investigations. His investigations are of a grammatical kind. His remarks are thus not at all aimed at arguing for what is in fact the case. They are to do with “giving prominence to distinctions which our ordinary forms of language easily make us overlook”, with drawing our attention to “what is possible before all new discoveries and inventions” – they are expressions of a concern with what already lies “seen but unnoticed” in the background to all our everyday (and professional) communicative activities.
