The many faces of Putnam's internal realism: a tribute

This article analyzes the many faces of Hilary Putnam's (1926-2016) internal realism. Although his thinking is marked by functionalism (a position he partially abandoned), it is in externalism and semantic holism that his key statements rest. Initially, we reconstruct how Putnam's thinking safeguards internal realism and a pragmatic position with respect to Wittgenstein. We then show how the author suggests that the psychophysical debate collapses after the acceptance of the value of semantic proprieties for the instantiation of mental content.
