Titre: « Rational learners and moral rules »

Résumé/abstract: Philosophical observation and psychological studies indicate that people draw subtle distinctions in the normative domain. But it remains unclear exactly what gives rise to such distinctions. On one prominent approach, emotion systems trigger non-utilitarian judgments. The main alternative, inspired by Chomskyan linguistics, suggests that moral distinctions derive from an innate moral grammar. In this paper, we develop a rational learning account. We argue that the “size principle”, which is implicated in word learning (Xu & Tenenbaum 2007), can also explain how children would use scant and equivocal evidence to interpret candidate rules as applying more narrowly than utilitarian rules.
