This paper develops a moderate pessimist account of moral deference. I argue that while some pessimist explanations of the puzzle of moral deference have been misguided in matters of detail, they nevertheless share an important insight, namely that there is a justified moral agency ideal grounded in pro tanto reasons against moral deference. This thought is unpacked in terms of a set of values associated with the practice of morality. I conclude by suggesting that the solution to the puzzle of moral deference developed here gives us a plausible recipe for generalizing to certain cases of nonmoral deference as well.

Philosophers think that there is something fishy about moral deference. The most common explanation of this fishiness is that moral deference doesn’t yield the epistemic states necessary for certain moral achievements (e.g., acting with moral worth or being virtuous). First, I argue that this explanation overgeneralizes. It entails that using many intuitively kosher belief-formation methods (e.g., abduction, reductio ad absurdum, and intuition) should be off-putting. Second, I argue that moral deference is sometimes superior to these other methods because it puts one in a better position to gain the relevant moral achievements.

My aim in this paper is to argue against what I call “epistemic” pessimism about moral testimony. Epistemic pessimists argue that moral testimony fails to transmit epistemic warrant as non-moral testimony does. I reject epistemic pessimism by defending the No Difference Thesis, that there is no in principle difference between the transmission of epistemic warrant by moral and non-moral testimony. The main thrust of my argument is that there is a good prima facie case to be made for the thesis, namely, that it is supported by all of the major current epistemological views of testimonial warrant, both reductionist and non-reductionist. After making this case, I consider five pessimist attempts to undermine the No Difference Thesis, and argue that none of these attempts succeeds. So, in the absence of any other compelling criticisms, we are justified in rejecting epistemic pessimism and accepting the No Difference Thesis.
