It seems that God does not exist; because if one of two contraries be infinite, the other would be altogether destroyed. But the word "God" means that He is infinite goodness. If, therefore, God existed, there would be no evil discoverable; but there is evil in the world. Therefore God does not exist.
Thomas AquinasIf a man deliberately abstains from wine to such an extent that he does serious harm to his nature, he will not be free from blame.
Thomas AquinasThere would not be a perfect likeness of God in the universe if all things were of one grade of being.
Thomas AquinasWithout the suitable conditions life could not exist. But both life and its conditions set forth the operations of inscrutable Power. We know not its origin; we know not its end. And the presumption, if not the degradation, rests with those who place upon the throne of the universe a magnified image of themselves, and make its doings a mere colossal imitation of their own. Wonder was the motive that led people to philosophy ... wonder is a kind of desire in knowledge. It is the cause of delight because it carries with it the hope of discovery.
Thomas Aquinas
