Neural Bases of the Thomistic Cardinal Virtues

This article develops an account of the neural bases of virtue by mapping contemporary neuroscience to the cardinal virtues guided by the anthropology of Thomas Aquinas. It argues that the four cardinal virtues, prudence, justice, fortitude, and temperance, provide a coherent and explanatorily powerful framework for interpreting the neurobiology of moral development. The study adopts a non-reductive hylomorphic anthropology grounded in a Thomistic metaphysics of participation, according to which rationality is embodied and neurally mediated yet irreducible to material processes, avoiding both reductive physicalism and dualism. Drawing on current research in neuroplasticity, habit formation, reward processing, emotional regulation, attention, metacognition, predictive processing, and social cognition, the paper identifies neural systems associated with each cardinal virtue according to its distinctive psychological function. Virtue is understood as a state of integrated systemic maturity that materially supports rational self-governance and moral agency. The resulting model offers a unified account of the relationship between character formation, moral action, neural development, and human flourishing, and reflects on the benefits of such neural studies for virtue ethics.
