Other naturalists have been more modest in the way in which they reconcile intentionality and naturalism. They maintain that intentional states may not be reducible to physical states, as Carrier appears to be arguing, but they do think that these states are supervenient upon physical states. They very often agree that there is a mystery as to how intentional states can exist in a physicalistic universe. This is certainly a possibility for the naturalist, but it runs the risk, as we shall see, of making propositional states epiphenomenal, that is, causally irrelevant. This will be a serious problem for the naturalist, since a naturalist presupposes the existence of mental causation when they argue on behalf of naturalism.
