On How to Act—Disjunctively

This paper revisits some issues discussed in the author’s Practical Reality. It responds to work by Jennifer Hornsby in particular. It considers various detailed suggestions about which form of disjunctivism is most appropriate in the theory of acting for a reason. Its general conclusion is, in line with what was argued in Practical Reality, that even the best form is unacceptable, but that the reasons why this is so are peculiar to the philosophy of action and so do not do anything to destabilise disjunctivism in the theory of perception. The paper also attempts to contribute to the understanding of disjunctivism more generally.
