Should you ask what this leads to, I think we may understand what that power is, and whence we have it. It certainly proceeds neither from the heart, nor from the blood, nor from the brain, nor from atoms. Whether it be air or fire, I know not, nor am I, as those men are, ashamed in cases where I am ignorant to own that I am so. If in any other obscure matter I were able to assert anything positively, then I would swear that the soul, be it air or fire, is divine. Just think, I beseech you: can you imagine this wonderful power of memory to be sown in or to be a part of the composition of the earth, or of this dark and gloomy atmosphere? Though you cannot apprehend what it is, yet you see what kind of thing it is, or if you do not quite see that, yet you certainly see how great it is. What, then? Shall we imagine that there is a kind of measure in the soul, into which, as into a vessel, all that we remember is poured? That indeed is absurd, for how shall we form any idea of the bottom, or of the shape or fashion of such a soul as that? And, again, how are we to conceive how much it is able to contain? Shall we imagine the soul to receive impressions like wax, and memory to be marks of the impressions made on the soul? What are the characters of the words, what of the facts themselves? and what, again, is that prodigious greatness which can give rise to impressions of so many things? What, lastly, is that power which investigates secret things, and is called invention and contrivance? Does that man seem to be compounded of this earthly, mortal, and perishing nature who first invented names for everything, which, if you will believe Pythagoras, is the highest pitch of wisdom? or he who collected the dispersed inhabitants of the world, and united them in the bonds of social life? or he who confined the sounds of the voice, which used to seem infinite, to the marks of a few letters? or he who first observed the courses of the planets, their progressive motions, their laws? These were all great men. But they were greater still who invented food, and raiment, and houses; who introduced civilization among us, and armed us against the wild beasts; by whom we were made sociable and polished, and so proceeded from the necessaries of life to its embellishments. For we have provided great entertainments for the ears by inventing and modulating the variety and nature of sounds; we have learned to survey the stars, not only those that are fixed, but also those which are improperly called wandering, and the man who has acquainted himself with all their revolutions and motions is fairly considered to have a soul resembling the soul of that Being who has created those stars in the heavens: for when Archimedes described in a sphere the motions of the moon, sun, and five planets, he did the very same thing as Plato’s God, in his Timaeus, who made the world, causing one revolution to adjust motions differing as much as possible in their slowness and velocity. Now, allowing that what we see in the world could not be effected without a God, Archimedes could not have imitated the same motions in his sphere without a divine soul.
To me, indeed, it appears that even those studies which are more common and in greater esteem are not without some divine energy: so that I do not consider that a poet can produce a serious and sublime poem without some divine impulse working on his mind; nor do I think that eloquence, abounding with sonorous words and
