Toujours traitees l'une a la suite de l'autre, la providence et la predestination s'appellent l'une l'autre et la seconde presuppose la premiere. Alors que la doctrine de la providence considere le gouvernement du monde par Dieu qui conduit toutes choses vers leur fin, l'enseignement sur la predestination s'attache a discerner ce qui s'applique specialement a la personne humaine. A forte teneur philosophique, la Question sur la providence revele une influence constante des divers traites de l'antiquite consacres a ce des stoiciens a Maimonide, en passant par Alexandre d'Aphrodise et Avicenne, le neoplatonisme arabe et le Livre des Causes, sans oublier les theologiens musulmans. A egale distance de deux erreurs l'occasionnalisme des theologiens musulmans du kalam d'un cote, l'emanatisme avicennien de l'autre, Thomas offre a son lecteur une philosophie chretienne de la providence dans laquelle sa theorie de l'autonomie des causes secondes permet de respecter simultanement la causalite libre de Dieu et celle de la creature. Plus specifiquement chretienne et theologique, la Question sur la predestination se developpe selon les memes principes. Sa lecture permet aussi de decouvrir l'influence d'Augustin sur un Thomas encore jeune et incertain par moments, mais aussi l'etat de la question avant qu'elle ne soit obscurcie par les discussions posterieures.
Philosophy of Saint Thomas Aquinas, a Dominican friar and theologian of Italy and the most influential thinker of the medieval period, combined doctrine of Aristotle and elements of Neoplatonism, a system that Plotinus and his successors developed and based on that of Plato, within a context of Christian thought; his works include the Summa contra gentiles (1259-1264) and the Summa theologiae or theologica (1266-1273).
People ably note this priest, sometimes styled of Aquin or Aquino, as a scholastic. The Roman Catholic tradition honors him as a "doctor of the Church."
Aquinas lived at a critical juncture of western culture when the arrival of the Aristotelian corpus in Latin translation reopened the question of the relation between faith and reason, calling into question the modus vivendi that obtained for centuries. This crisis flared just as people founded universities. Thomas after early studies at Montecassino moved to the University of Naples, where he met members of the new Dominican order. At Naples too, Thomas first extended contact with the new learning. He joined the Dominican order and then went north to study with Albertus Magnus, author of a paraphrase of the Aristotelian corpus. Thomas completed his studies at the University of Paris, formed out the monastic schools on the left bank and the cathedral school at Notre Dame. In two stints as a regent master, Thomas defended the mendicant orders and of greater historical importance countered both the interpretations of Averroës of Aristotle and the Franciscan tendency to reject Greek philosophy. The result, a new modus vivendi between faith and philosophy, survived until the rise of the new physics. The Catholic Church over the centuries regularly and consistently reaffirmed the central importance of work of Thomas for understanding its teachings concerning the Christian revelation, and his close textual commentaries on Aristotle represent a cultural resource, now receiving increased recognition.
