Last week JESP accepted a discussion note I sent them not too terribly long ago and this afternoon they sent me a proof to correct. That's fast! "On Treating Something as a Reason for Action" is a response to critics who have attacked Hawthorne and Stanley's Knowledge-Reasons Principle:
(KRP) When S’s choice is p-dependent, it is permissible for S to treat the proposition that p as a reason for acting if and only if S knows that p.
The critics I'm concerned with think that a justified belief that p is the case (or that p is known to be the case) should suffice for a permission to treat p as a reason for action. I argue that this cannot be right (unless everyone is badly mistaken about what it is to have a justified belief, in which case KRP isn't wrong for the reasons critics say it is). All the pieces I criticize are forthcoming and shouldn't be in print until after my discussion note goes public, which makes this my first preemptive discussion note. Cool.
