La providencia en santo Tomás de Aquino

According to Aquinas, divine omniscience, omnipotence and providence, do not contradict the existence of either true contingency in the natural world or freedom but, on the contrary, they support them. In short, the two peculiarities of the doctrine of providence in St. Thomas here exposed are: first, that God's will is the ultimate foundation of all contingency (and not merely the deficiency of secondary causes); second, that the divine causality cannot be reduced to any of the two groups of created causes (necessary or contingent) but it is only known to us by analogy
