The Metaphysics of Thought: A Response to Fish and Macdonald

John McDowell’s position on the metaphysics of thought combines an identity conception of truth, the view that if one thinks truly that p, then what one thinks is the fact that p, with a Tractarian conception of the world as the totality of facts. In response to the charge that it is incoherent, William Fish and Cynthia Macdonald have recently (2007, 2009, 2011) defended a novel way of developing McDowell’s position. I argue that their interesting proposal doesn't work, owing to the fact that it can accommodate neither false thought nor, it seems, certain cases of true thought.
