Hilary Putnam has argued against philosophical theories which tie the content of truth-claims closely to the available methods of investigation and verification. Such theories, he argues, threaten our idea of human communication, which we take to be possible between people of different cultures and across periods of time during which methods of investigation change dramatically. Putnam rejects any reading of Wittgenstein which takes him to make a close tie between meaning and method of verification. What strands in Wittgenstein's thought appear to lend support to such a reading? Can we do justice to the role which method of verification does have for Wittgenstein while retaining our hold on the idea that communication between people is possible despite substantial differences in methods of verification and investigation? Thus it is as if the proof did not determine the sense of the proposition proved; and yet as if it did determine it. But isn't it like that with any verification of any proposition?
