Thomas Aquinas devoted a substantial proportion of his greatest works to the virtues. Yet despite the availability of these texts (and centuries of commentary) Aquinasâs virtue ethics remains mysterious leaving readers with many unanswered questions. In this book Pinsent argues that the key to understanding Aquinasâs 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 Aquinasâs 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 Aquinasâs 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. . Language: English
