Why there are no phenomenal concepts, and what physicalists should do about it

It is widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. The orthodox view among contemporary philosophers of mind that these phenomenal concepts provide the key to understanding the dispute between physicalists and their opponents. I reject the orthodox view; I defend an externalist conception of mental content according to which there are no phenomenal concepts. But the fact that there are no phenomenal concepts should not worry the physicalist: there are better accounts of the data that phenomenal concepts are used to explain.
