wants to know. Fortunately, while I got a C+ in my one class on American politics and public policy, this is actually something I know about thanks to the tireless labors of

Truth and Other Enigmas. I think Ross won't be thrilled with the somewhat relativistic conclusions, but the good news from his point of view is that my understanding is that Dummett is a practicing Catholic.
