The Epistemology of Moral Progress: Can Moral Truths be Objectively Known Across Cultural Philosophies?

Project Abstract

Moral progress has long been a contested ideal, oscillating between universalist claims of objective moral truths and situated, culturally specific judgments. This study interrogates whether epistemic access to moral truths can be harmonized with the pluralism of cultural philosophies, arguing that a robust account of moral progress must synthesize non-cognitivist, realist, and constructivist insights while remaining attentive to historical contingencies. Building on debates in moral epistemology, metaethics, and comparative ethics, the research advances a framework that distinguishes epistemic warrant from moral endorsement, thereby allowing cross-cultural convergence on certain evaluative criteria without collapsing moral diversity into a monolithic standard. The central hypothesis is that moral truths, insofar as they are intelligible and contestable, can be constrained by universal rational norms (coherence, well-being, autonomy, and rights) while being shaped by culturally situated justificatory practices, narrative traditions, and social practices. Methodologically, the study adopts a multi-layered approach a theoretical analysis that critiques prevailing epistemic models of moral knowledge; an exegetical survey of key philosophical traditions across Western, African, East Asian, and Indigenous philosophies; and an empirical-analytic component that analyzes contemporary public discourse, policy debates, and case studies of reform movements to identify patterns of cross-cultural moral reasoning and disagreement. The research identifies three epistemic regimes guiding moral progress universalist rationalism, culturally specific constructivism, and dialogical pluralism. It shows how progress can be assessed through criteria such as justification adequacy, transformative potential, inclusive deliberation, and empirical coherence with human flourishing. The study further investigates the role of moral emotions, empathy, and moral imagination in bridging gaps between cultures, and critiques the assumption that objectivity requires neutral vantage points, proposing instead a situated objectivity that acknowledges standpoint diversity. By examining historical episodes of moral reform—such as abolition, gender equality, and minority rights—the work demonstrates how cross-cultural dialogues can yield incremental moral insights without erasing local meanings. The findings suggest that moral truths emerge through iterative processes of cross-cultural critique, mutual revision, and public justification, supported by institutions that foster transparent reasoning, plural accountability, and evidence-based evaluation. The implications extend to theory formation in ethics, political philosophy, and the sociology of knowledge, offering a plausible account of how moral progress can be objectively appraised without diminishing cultural plurality. Policy implications are considered, including how international human rights frameworks can be informed by dialogical pluralism to enhance legitimacy and effectiveness. The study also identifies future research avenues, such as the integration of cognitive science findings on moral perception with cross-cultural epistemology and the development of methodological tools for comparative moral assessment. In sum, the research contributes to a nuanced account of moral epistemology that sustains the possibility of objective knowledge claims about moral progress while respecting and incorporating the rich diversity of global moral philosophies.

Expected Outcome

A clear, accessible account that outlines when moral truths might be considered objectively known, along with a usable framework for evaluating moral progress across cultures. The project should help readers understand the strengths and limits of cross-cultural claims to moral knowledge and provide guidance for future scholarship and ethical analysis.
