This paper concerns what I take to be the primary epistemological motivation for defending moral perception. Offering a plausible account of how we gain moral knowledge is one of the central challenges of metaethics. It seems moral perception might help us meet this challenge. The possibility that we know about the instantiation of moral properties in something like the way we know that there is a bus passing in front of us raises the alluring prospect of subsuming moral epistemology under (...) the comfortable umbrella of perceptual or, more broadly, empirical knowledge. The good news on this front is that various combinations of metaethical positions and theories of perception arguably have the potential to vindicate moral perception. The bad news, I’ll argue, is that moral perception would be dependent for its epistemic merit on background knowledge of bridge principles linking moral and non-moral properties. Thus, in order to defend a purely perceptual moral epistemology, one would have to argue that knowledge of those principles is likewise perceptual. I further argue it is not. (shrink)

Many people argue that history makes a special difference to the subjects of biology and psychology, and that history does not make this special difference to other parts of the world. This paper will show that historical properties make no more or less of a difference to biology or psychology than to chemistry, physics, or other sciences. Although historical properties indeed make a certain kind of difference to biology and psychology, this paper will show that historical properties make the same (...) kind of difference to geology, sociology, astronomy, and other sciences. Similarly, many people argue that nonhistorical properties make a special difference to the nonbiological and the nonpsychological world. This paper will show that nonhistorical properties make the same difference to all things in the world when it comes to their causal behavior and that historical properties make the same difference to all things in the world when it comes to their distributions. Although history is special, it is special in the same way to all parts of the world. (shrink)
