A trait that is often associated with a good person is caring about the truth. Thomas Aquinas, following Aristotle, describes a virtue that concerns truths (truthfulness). However, he limits the virtue to being truthful about who one is and what one's achievements are. This restriction seems almost arbitrary and exceedingly narrow. In this paper, I explore the motivation for Aquinas's restricted account and argue that his view is motivated by broader virtue theoretical commitments and that his approach to the role (...) of truth for being a good person is distinct and worthwhile.
