A filosofia moral de São Tomás de Aquino

This brief study, something like a brief philosophical essay, seems to recall three theses on the moral ‘philosophy’ of St. Thomas Aquinas, not always taken sufficiently into account: firstly, the novelty of introducing Aristotelian ethics only in the second part, particularly in the first section, of the Summa Theologiae; followed by the motives for introducing a philosophical ethics, a discipline of practical reason, in a theology notably speculative; lastly, a partial rupture initiated by St. Thomas in relation to the traditional framework of ethics of Saints Augustine and Anselm.
