In his book Mind and World (1994), John McDowell defends the Kantian positi
on that the content of experiences is conceptual. Without this Kantian assu
mption, he argues, it would be impossible to understand how experience may
rationally constrain thought. But McDowell's Kantianism is either false or
empty, and his view of the relation between mind and world cannot be stated
without transcending the bounds of sense. McDowell's arguments supporting
the Kantian thesis, which are very different from Kant's arguments, essenti
ally involve a fallacy of ambiguity. In order to understand how thought may
be rationally constrained by experience we should become empiricists.
