Paul Horwich is Professor Philosophy at NYU. He has worked in a number of areas of philosophy, but is especially well-known for his writing on the philosophy of language, particularly with regard to truth and meaning—naturally, he has books by the same names, Truth (Oxford, 1990) and Meaning (Oxford, 1998). Robinson and Paul discuss the relationship between his work on these topics and the philosophy he started off researching—science and physics—before moving on to the question of philosophical realism across a number of domains before focusing on moral realism and whether there are such things as moral facts. OUTLINE:Robinson’s Website: http://robinsonerhardt.comRobinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.
