Abstract
While most theorists agree with the claim that human beings have high and equal moral standing, there are strong disagreements about how to justify this claim. These disagreements arise because there are different ways of managing the difficulty of finding a basis for this claim, which is sufficiently substantial to do this justifying work, but not vary in degree in order to not give rise to inequality of moral considerability. The aim of this paper is to review previous attempts to address this difficulty and to demonstrate why they fail and then to defend another way of dealing with this challenge by applying two views: the substance view on the human person and the natural-law account of morality. My claim is that this approach has comparative advantages because it provides a binary and a normatively significant basis of justification for equality without being implausibly inclusive.
