This paper offers a metaethical analysis of so-called political moralism’s metaethical assumptions and proposes shifting away from them. It does so by taking migration ethics’ methodology as a case study of the field. First, the paper shows political moralism’s commitment to moral monism and moral overridingness. Second, it explains how such commitments are likely to lead to the formulation of toy theories - and, hence, moral regress. Third, it proposes the recognition of prudential normativity and normative pluralism as a way (...) to avoid the toy theory problem. And, fourth, it deals with two objections to this proposal.
