Comparative Analysis of Moral Epistemology in Virtue Ethics and Deontological Frameworks

Thesis Abstract

This study investigates the comparative dimensions of moral epistemology within virtue ethics and deontological frameworks, addressing the ongoing debate over how moral knowledge is acquired, justified, and validated in different normative ethical systems. Recognizing that virtue ethics emphasizes moral intelligibility through character and practical wisdom (phron?sis), whereas deontology prioritizes adherence to moral duties grounded in rational principles, the research seeks to elucidate the underlying epistemic justifications that support moral judgments in these contrasting paradigms. The primary aim is to analyze the epistemological assumptions, justificatory processes, and reliability of moral knowledge as envisioned by both frameworks, with particular focus on the theories of Aristotle’s virtue ethics and Immanuel Kant’s deontology. The study adopts a comparative, qualitative research design underpinned by a hermeneutic phenomenological approach to explore the philosophical narratives of moral cognition in the specified theories. The research population comprises 30 postgraduate philosophy students and scholars drawn from three major universities with specialized ethics programs, purposively sampled to include experts familiar with virtue ethics and deontology. Data collection is carried out through semi-structured interviews and document analysis of primary texts and secondary commentaries, with instruments validated through expert peer review and pilot testing to ensure clarity, coherence, and depth of insights. Data analysis employs thematic analysis coupled with structured content analysis to identify common patterns, divergences, and underlying assumptions concerning moral knowledge acquisition. Thematic coding utilizes NVivo software, with triangulation used to enhance validity. The analysis aims to compare epistemic conditions such as the role of moral intuition, rational deduction, moral perception, and character development, while also exploring factors influencing the perceived reliability and universality of moral knowledge in each framework. Key findings are anticipated to reveal significant differences in the epistemic foundations of virtue ethics and deontology. It is expected that virtue ethicists view moral knowledge as rooted in experiential understanding and cultivated virtues that facilitate moral perception, contributing to moral wisdom, whereas deontologists regard moral knowledge as derived from rational deduction and adherence to universal moral laws. The research further anticipates identifying areas of epistemological tension, such as the subjective-intersubjective divide and the scope of moral justification, which influence ethical decision-making and moral education. The study contributes to existing philosophical discourse by providing a detailed comparison of the epistemological underpinnings of two dominant ethical theories, filling a gap in contemporary moral epistemology literature. Moreover, it offers a refined conceptual model illustrating how different epistemic processes interact within virtuous character formation and rational duty execution, thereby advancing theoretical understanding and practical implications for moral pedagogy and ethical appraisal. The main conclusion underscores that while virtue ethics emphasizes moral perception and character development as key epistemic sources, deontological approaches rely heavily on rational deduction and universal principles. It recommends that moral education incorporate both experiential and rational components to foster comprehensive moral knowledge. The study suggests further research to empirically assess the influence of these epistemic practices on moral behavior and decision-making in diverse cultural settings, potentially informing interdisciplinary approaches to ethics education and policy formulation.
