The Epistemology of Moral Intuition: Analyzing the Role of Sentimental Reasoning in Ethical Knowledge

Project Abstract

This study investigates how moral intuition, shaped by sentimental reasoning, contributes to ethical knowledge and the epistemic status of moral judgments within contemporary ethical theory. By integrating analytic and experimental approaches, it examines whether intuitive moral verdicts can serve as justificatory grounds or whether they require reconstruction through reflective equilibrium, virtue-theoretic considerations, or empirical validation of moral psychology. The research engages with perennial debates on moral epistemology, including foundationalism versus coherentism, the reliability of affective processes, and the role of moral talk in ontological versus pragmatic understanding of ethical truths. A critical objective is to delineate the conditions under which sentimental reasoning yields cognitively warranted moral beliefs, and to identify systematic biases (such as affective disgust, empathy gaps, or cultural conditioning) that may distort epistemic access to ethical properties. The methodology combines conceptual analysis, thought experiments, and qualitative data from moral psychology experiments to map the inferential structure linking felt obligation, emotional salience, and normative justification. The study investigates the interface between moral emotion and moral reason, evaluating whether sentiments function as proximate sources of moral knowledge or as heuristics that presuppose prior rational endorsement. It also interrogates cross-cultural variability in moral intuitions and their impact on universalist or relativist claims about ethical knowledge, paying particular attention to the role of socialization, narrative framing, and moral education. The research further explores the status of disagreement among intuitions across individuals and groups, addressing how such disputation informs or undermines claims to objective ethical understanding. A central contribution is a normative framework that articulates a hierarchy of justificatory criteria for moral intuitions, integrating epistemic virtue with cognitive science insights into affective processing. The study assesses the extent to which sentimental reasoning can operate as a reliable guide to moral truth in domains such as altruism, justice, and rights, and whether sentimental content must be complemented by deontic, consequentialist, or virtue-based analyses to achieve robust ethical knowledge. Implications for moral pedagogy, policy design, and AI alignment are discussed, highlighting how an empirically informed account of moral intuition can improve ethical deliberation and reduce error in moral judgments. By clarifying the epistemic role of sentiment in moral cognition, the research aims to offer a nuanced account that reconciles the phenomenology of moral experience with rigorous criteria for justification, thereby contributing to contemporary debates on the foundations and practice of moral knowledge.
