The theory of radical interpretation, as based on the principle of charity, sets a priori limits on the possibility that different agents have different beliefs, and on the possibility that one has false beliefs. David Papineau put forward a teleological approach to intentional states which, he claims, doesn’t have these unacceptable consequences. Having distinguished half a dozen of different forms that the problem of radical interpretation might take, I show that Papineau’s approach is not radically different from those based on the principle of charity. Finally, I suggest that the consequences of the principle of charity with respect to the problems of error and divergence are in fact both unavoidable and acceptable.

It has been said that Robert Boyle gave in the century of The Scientific Revolution the “fullest expression” of the view that laws of nature are continually impressed by God (“occasionalism”). So regarded, the universe is anything but an autonomous machine, its ordered operation depending on God’s continuous imposition of lawful, patterned relations between phenomena and his continuous provision of motion for them to actually enter relations. The present paper contests this treatment of Boyle. Evidence is elicited to show that, for Boyle, most physical relations issue from intrinsic dispositions of phenomena, not divine impositions, dispositions determined by corpuscular textures. Members of classes of phenomena have capacities to make specific changes which members of other classes have capacities to receive, these correlative capacities being necessarily connected, subjects in principle of a priori synthetic necessary knowledge. The same view is found in John Locke’s Essay Concerning Human Understanding. It is additionally argued that Boyle’s God, the quintessentially active being, imparted motion at the creation, whereafter the motion of (at least most) natural phenomena has derived from natural, not supernatural, impulsion.
