3 Now that the human race possesses its knowledge of God by nature and not from teaching is proved to us first of all by the universal yearning for the divine that is in all men whether private persons or communities, whether considered as individuals or as races. For all of us, without being taught, have attained to a belief in some sort of divinity, though it is not easy for all men to know the precise truth about it, nor is it possible for those who do know it to tell it to all men. . . .1 Surely, besides this conception which is common to all men, there is another also. I mean that we are all by nature so closely dependent on the heavens and the gods that are visible therein, that even if any man conceives of another god besides these, he in every case assigns to him the heavens as his dwelling-place; not that he thereby separates him from the earth, but he so to speak establishes the King of the All in the heavens as in the most honourable place of all, and conceives of him as overseeing from there the affairs of this world.
4 What need have I to summon Hellenes and Hebrews as witnesses of this? There exists no man who does not stretch out his hands towards the heavens when he prays; and whether he swears by one god or several, if he has any notion at all of the divine, he turns heavenward. And it was very natural that men should feel thus. For since they observed that in what concerns the heavenly bodies there is no increase or diminution or mutability, and that they do not suffer any unregulated influence, but their movement is harmonious and their arrangement in concert; and that the illuminations of the moon are regulated, and that the risings and settings of the sun are regularly defined, and always at regularly defined seasons, they naturally conceived that the heaven is a god and the throne of a god. For a being of that sort, since it is not subject to increase by addition, or to diminution by subtraction, and is stationed beyond all change due to alteration and mutability, is free from decay and generation, and inasmuch as it is immortal by nature and indestructible, it is pure from every sort of stain. Eternal and ever in movement, as we see, it travels in a circuit about the great Creator, whether it be impelled by a nobler and more divine soul that dwells therein, just as, I mean, our bodies are by the soul in us, or having received its motion from God Himself, it wheels in its boundless circuit, in an unceasing and eternal career.
