This paper seeks to clarify one of the deepest questions about the source or ground of normativity, while also presenting an essence-based approach to answering it. We call it the ‘Arché Question.’ Though all metanormative theories must address this question, very few realists have explicitly grappled with the challenge it poses; those who have appear to deny any need to give an answer. After critically discussing extant realist responses, this paper outlines an essence-based approach to answering the Arché Question that (...) draws on theoretical resources forged in recent advances in post-modal metaphysics.

Richard Price’s moral epistemology provides a distinctive account, not only of the sources of our moral knowledge, but also of its limits – that is, of the moral truths that we do not and even cannot know. According to this moral epistemology, the fundamental moral truths are necessary rather than contingent; if they are knowable at all, they are knowable a priori. In general, fundamental moral truths are akin to mathematical truths. Specifically, these necessary moral truths are grounded in the (...) essences of act-types, which are knowable through ‘intuition’ if knowable at all. However, Price firmly rejects utilitarianism, recognizing several different ‘branches of virtue’, which can conflict with each other. As he argues, we cannot know the truth about act-types that exemplify such conflicting branches of virtue if the competing considerations are too finely balanced. This view of moral epistemology is compared with those of several other philosophers, including W. D. Ross. It is argued that Price has a more unified view than Ross: for Price, all moral knowledge flows from a priori intuition, but this is compatible with our being ignorant of many of the fine details of the fundamental truths of morality.
