Pragmatic Realism


  • Hasok Chang University of Cambridge



Pragmatism, realism, pluralism, coherence, truth, reality


In this paper I seek to articulate and develop Roberto Torretti’s advocacy of pragmatic realism. At the core of Torrietti’s view is a rejection of the notion that the truth of scientific theories consists in their correspondence to the world. I propose to understand correspondence in that sense as a metaphorical notion. I articulate a notion of pragmatist coherence, on the basis of which I make new coherence theories of truth and reality. Then it becomes possible to say that pragmatic realism consists in the pursuit of true knowledge of reality, in a way that is also consonant with Torretti’s pluralism.
