The question of idealism in McDowell

John McDowell has attempted to defend himself against the charge that the view presented in his influential book Mind and World is idealist. This paper argues that in spite of that defence, there is a clear way in which the view does depend on a form of idealism. McDowell is committed to the thought that the world is ‘conceptually organized’. I consider what this means, and argue that, although it does not formally imply idealism, it is only defensible from a broadly idealist view—one which is in fact in tension with important claims made by McDowell in other works.
