Moral knowledge and moral factuality

For naturalistic and non-intuitionistic moral realists, moral knowledge is more problematic than ordinary and scientific factual knowledge. For without special faculties of moral discernment, how could we ever detect moral facts and properties? Physical facts and properties may be accessible to perceptual recognition. But how could moral facts and properties ever be similarly accessible? To address this challenge, we need a meta-ethical account that does two things. First, it must explain how the discernment of moralfacts and properties ultimately consists only of the detection of appropriate physical items. Second, it must explain why, despite this fact, moral perception seems so very puzzling. In this paper I endeavor to provide such an account. It is largely because of the relational nature of moral properties, and thecorresponding externalistically determined normative content of moral property terms, I argue, that our epistemic access to moral knowledge appears mysterious. The metaphysics of moral factuality does a lot to explain the seeming elusiveness of moral knowledge, and in ways that are surprisingly mundane
