There is no Argument that the Mind Extends On the basis of two argumentative examples plus their 'parity principle', Clark and Chalmers argue that mental states like beliefs can extend into the environment. I raise two problems for the argument. The first problem is that it is more difficult than Clark and Chalmers think to set up the Tetris example so that application of the parity principle might render it a case of extended mind. The second problem is that, even when appropriate versions of the argumentative examples can be constructed, the availability of a second, internalist parity principle precludes the possibility of inferring that the mind extends. Choosing which parity principle we ought to wield would involve deciding beforehand whether or not the mind can extend. Thus Clark and Chalmers beg the question by employing their parity principle rather than the internalist one. I conclude that they fail to provide a proper argument to support the extended mind thesis.

In this paper I first examine two important assumptions underlying the argument that physicalism entails panpsychism. These need unearthing because opponents in the literature distinguish themselves from Strawson in the main by rejecting one or the other. Once they have been stated, and something has been said about the positions that reject them, the onus of argument becomes clear: the assumptions require careful defence. I believe they are true, in fact, but their defence is a large project that cannot begin here. So, in the final section I comment on what follows if they are granted. I agree with Strawson that --broadly -- 'panpsychism' is the direction in which philosophy of mind should be heading; nevertheless, there are certain difficulties in the detail of his position. In light of these I argue for changes to the doctrine, bringing it into line with the slightly.
