  In a similar vein, Wilson (2004) discusses a person who wishes to solve a multiplication problem involving two large numbers. Calculating the product “in the head” is a possibility, but solving the problem with the aid of pencil and paper would be much easier. In the latter case, Wilson claims that the brain “offloads” onto the paper some of the work that it would otherwise have to do on its own. Crucial to Wilson’s argument is the idea that solving the multiplication problem is a computational process and that computational processes are not confined to particular spatial regions. When the multiplication problem is solved “in the head” the computational processes occur within the brain alone. But some of the steps in the computation could as well take place outside the head, on a piece of paper, in which case a computational process might partly occur outside the head. There is, then, a parity in the two processes, whether the particular computations are internal or external to the agent. To the extent that this is plausible, one can find additional support for Constitution.
