The Divine Institutes

And because Epicurus or Democritus was unable to teach this, he said that it was produced of its own accord, the seeds coming together in all directions; and that when these are again resolved, discord and destruction will follow. Therefore he perverted that which he had correctly seen, and by his ignorance of system entirely overthrew the whole system, and reduced the world, and all things which are done in it, to the likeness of a most trifling dream, if no plan exists in human affairs.

But since the world and all its parts, as we see, are governed by a wonderful plan; since the framing of the heaven, and the course of the stars and of the heavenly bodies, which is harmonious even in variety itself, the constant and wonderful arrangement of the seasons, the varied fruitfulness of the lands, the level plains, the defences and heapings up of mountains, the verdure and productiveness of the woods, the most salubrious bursting forth of fountains, the seasonable overflowings of rivers, the rich and abundant flowing in of the sea, the opposite and useful breathing of the winds, and all things, are fixed with the greatest regularity: who is so blind as to think that they were made without a cause, in which a wonderful disposition of most provident arrangement shines forth?

If, therefore, nothing at all exists nor is done without a cause; if the providence of the Supreme God is manifest from the disposition of things, His excellency from their greatness, and His power from their government: therefore they are dull and mad who have said that there is no providence. I should not disapprove if they denied the existence of gods with this object, that they might affirm the existence of one; but when they did it with this intent, that they might say that there is none, he who does not think that they were senseless is himself senseless.
