Abstract

Is Aquinas’s Sententia libri Ethicorum to be classified as a theological or philosophical commentary? In embracing the latter answer, Doig promotes Hermann Kleber’s view that Aquinas, in the SLE and other Aristotelian commentaries, searches for the “intentio Aristotelis, while keeping in mind the veritas rei”, a truth that, if it is reached through a demonstration that does not incorporate any premise formally based on Christian faith, Doig unhesitatingly calls “philosophical reasoning”. Although R. A. Gauthier dates the SLE 1271–72, Doig argues that it was written after both parts, and was not, therefore, “preparatory to the ‘moral part’ of the Summa [theologiae, ]”. Instead, Doig argues that Aquinas, in the SLE, presents a different genus of moral science: his own philosophical “vision of correct moral philosophy”, that is a personally reworked version of Aristotle.
