This study locates Aquinas’s theory of infused and acquired virtue in his foundational understanding of nature and grace. Aquinas holds that all the virtues are bestowed on humans by God along with the gift of sanctifying grace. Since he also holds, with Aristotle, that we can create virtuous dispositions in ourselves through our own repeated good acts, a question arises: How are we to understand the relationship between the virtues God infuses at the moment of grace and virtues that are gradually acquired over time? In this important book, Angela McKay Knobel provides a detailed examination of Aquinas’s theory of infused moral virtue, with special attention to the question of how the infused and acquired moral virtues are related. Part 1 examines Aquinas’s own explicit remarks about the infused and acquired virtues and considers whether and to what extent a coherent “theory” of the relationship between the infused and acquired virtues can be found in Aquinas. Knobel argues that while Aquinas says almost nothing about how the infused and acquired virtues are related, he clearly does believe that the “structure” of the infused virtues mirrors that of the acquired in important ways. Part 2 uses that structure to evaluate existing interpretations of Aquinas and argues that no existing account adequately captures Aquinas’s most fundamental commitments. Knobel ultimately argues that the correct account lies somewhere between the two most commonly advocated theories. Written primarily for students and scholars of moral philosophy and theology, the book will also appeal to readers interested in understanding Aquinas’s theory of virtue.

Aquinas on Virtue is an original interpretation of one of the most compelling accounts of virtue in the Western tradition, that of the great theologian and philosopher Thomas Aquinas. This book offers a systematic analysis of Aquinas on the nature, genesis, and role of virtue in human life.

Thomas Aquinas devoted a substantial proportion of his greatest works to the virtues. Yet, despite the availability of these texts (and centuries of commentary), Aquinas’s virtue ethics remains mysterious, leaving readers with many unanswered questions. In this book, Pinsent argues that the key to understanding Aquinas’s approach is to be found in an association between: a) attributes he appends to the virtues, and b) interpersonal capacities investigated by the science of social cognition, especially in the context of autistic spectrum disorder. The book uses this research to argue that Aquinas’s approach to the virtues is radically non-Aristotelian and founded on the concept of second-person relatedness. To demonstrate the explanatory power of this principle, Pinsent shows how the second-person perspective gives interpretation to Aquinas’s descriptions of the virtues and offers a key to long-standing problems, such as the reconciliation of magnanimity and humility. The principle of second-person relatedness also interprets acts that Aquinas describes as the fruition of the virtues. Pinsent concludes by considering how this approach may shape future developments in virtue ethics.

In his Treatise on the Virtues, Aquinas discusses the character and function of habit; the essence, subject, cause, and meaning of virtue; and the separate intellectual, moral, cardinal, and theological virtues. His work constitutes one of the most thorough and incisive accounts of virtue in the history of Christian philosophy. John Oesterle's accurate and elegant translation makes this enduring work readily accessible to the modern reader.

Thomas Aquinas offers teleological systematisation of the habits needed for human flourishing. His metaphysical jurisprudence remodels ethics upon this, rather than on a moral precept. “Eternal law” governing the world determines “natural law”, reflected in human legislation (a variety of the “anthropic principle”). Finally, law, unwritten, is infused spirit as self-consciousness, “universal of universals”. Acquired virtues elicit this, become effusion, represented in religion as gifts or graces. But mind’s or spirit’s omnipresence, necessarily “closer to me than I am to myself”, supersedes the abstractions of heteronomy versus autonomy. The habitual well-being brought by prudence, justice, courage and temperance prompts this picture of gifts and graces. The “theological virtues”, faith (explicit or implicit) and hope fulfilled in love, “crown” our natural rationality, set toward as being the universal. “Become what you are”. Heteronomous law is thus “defused” at root by grounding it entirely upon immovable spiritual (mental) inclination towards universal fulfilment as naturally desired, reflection shows. Virtue, finally, is best assessed as a capacity for the individually beautiful yet habit-based action, Aristotle’s to kalon. Aquinas puts this picture as summed up in the beatitudes of the “Sermon on the Mount”.
