Summa Theologiae Prima Pars, 50-119 (Latin-English Edition)

The most important work of the towering intellectual of the Middle Ages, Thomas Aquinas's Summa Theologiae remains one of the great seminal works of philosophy and theology, while extending to subjects as diverse as law and government, sacraments and liturgy, and psychology and ethics. Aquinas continues his Summa Theologiae with meditations on persons, both spiritual and corporeal, angels and humans.
