Human Nature According to Thomas Aquinas and Its Implications for Today's Social Life

Abstract: This article investigates Thomas Aquinas’s conceptualization of human nature, which emerges from a sophisticated synthesis of Aristotelian philosophy and Christian theology, and explores its relevance to contemporary social existence. Aquinas posits humanity as a "rational animal," inherently disposed toward the common good, governed by natural law, and oriented toward ultimate fulfillment in divine communion (Aquinas, 1265-1274). Through an analysis of primary texts and secondary scholarship, this study elucidates how Aquinas’s perspective—rooted in reason, virtue, and communal harmony—provides a compelling framework for addressing modern societal dilemmas, including rampant individualism, moral disintegration, and pervasive social inequities. The findings reveal that Aquinas’s theoretical construct champions a harmonious equilibrium between individual autonomy and collective obligation, presenting a stark counterpoint to the dominant paradigms of secular liberalism and utilitarianism in today’s intellectual landscape. Central implications of this inquiry encompass the revitalization of virtues to foster social solidarity, a nuanced rearticulation of natural law within a pluralistic framework, and the practical application of Aquinas’s philosophy to pressing ethical concerns-such as social justice and environmental stewardship—with particular resonance for contemporary Vietnam.
