 Aquinas discussed the issues of synderesis and conscience in several of his major works, from his early commentary on the Sentences and the De veritate to his mature Summa theologica (see D’Arcy 1961: 36–47). As might be expected, his account is very different from that of his Franciscan contemporary Bonaventure. For one thing, Bonaventure assigns synderesis to the will. He also describes it, as we saw above, as a “habit-like faculty”. Aquinas, as might be expected, hews much closer to his Dominican mentor and teacher Albert the Great (ca. 1200–1280) for whom both synderesis and conscience belong to the intellect (see Dougherty 2018: 221).
