Abstract
In this essay, I hope to make clearer what the points of division between the materialists and the sceptics are. I argue that the rifts are quite deep and turn on basic differences in understanding the scientific enterprise. In section I, I outline the disagreements between David Chalmers and me, arguing that consciousness is not a brute fact about the world. In section II, I point out the fundamental difference between the materialists and the sceptics, suggesting that this difference is not something that further discussion or argumentation can overcome. In the final section, I outline one view of scientific explanation and conclude that the source of conflict really turns on a difference in the rules each side has adopted in playing the game
