  Now if the content of Lilian’s thought that there is a tree in the quad is “broad”, if the significance of her thought depends on factors outside Lilian’s body, then it is indeed hard to see how this content could figure in a causal account of her actions, including Lilian’s expressing her belief that there is a tree in the quad by uttering the sentence, “There is a tree in the quad”. This is bad news for any attempt to explain why we do what we do by reference to the contents of our thoughts.
