must necessarily cease to exist. That, therefore, alone, which is self-moved, because it is never forsaken by itself, can never cease to be moved. Besides, it is the beginning and principle of motion to everything else; but whatever is a principle has no beginning, for all things arise from that principle, and it cannot itself owe its rise to anything else; for then it would not be a principle did it proceed from anything else. But if it has no beginning, it never will have any end; for a principle which is once extinguished cannot itself be restored by anything else, nor can it produce anything else from itself; inasmuch as all things must necessarily arise from some first cause. And thus it comes about that the first principle of motion must arise from that thing which

       is itself moved by itself; and that can neither have a beginning nor an end of its existence, for otherwise the whole heaven and earth would be overset, and all nature would stand still, and not be able to acquire any force by the impulse of which it might be first set in motion. Seeing, then, that it is clear that whatever moves itself is eternal, can there be any doubt that the soul is so? For everything is inanimate which is moved by an external force; but everything which is animate is moved by an interior force, which also belongs to itself. For this is the peculiar nature and power of the soul; and if the soul be the only thing in the whole world which has the power of self-motion, then certainly it never had a beginning, and therefore it is eternal."

       Now, should all the lower order of philosophers (for so I think they may be called who dissent from Plato and Socrates and that school) unite their force, they never would be able to explain anything so elegantly as this, nor even to understand how ingeniously this conclusion is drawn. The soul, then, perceives itself to have motion, 33and at the same time that it gets that perception, it is sensible that it derives that motion from its own power, and not from the agency of another; and it is impossible that it should ever forsake itself. And these premises compel you to allow its eternity, unless you have something to say against them.

       A. I should myself be very well pleased not to have even a thought arise in my mind against them, so much am I inclined to that opinion.

       XXIV. M. Well, then, I appeal to you, if the arguments which prove that there is something divine in the souls of men are not equally strong? But if I could account for the origin of these divine properties, then I might also be able to explain how they might cease to exist; for I think I can account for the manner in which the blood, and bile, and phlegm, and bones, and nerves, and veins, and all the limbs, and the shape of the whole body, were put together and made; ay, and even as to the soul itself, were there nothing more in it than a principle of life, then the life of a man might be put upon the same footing as that of a vine or any other tree, and accounted for as caused by nature; for these things, as we say, live. Besides, if desires and aversions were all that belonged to the soul, it would have them only in common with the beasts; but it has, in the first place, memory, and that, too, so infinite as to recollect an absolute countless number of circumstances, which Plato will have to be a recollection of a former life; for in that book which is inscribed Menon, Socrates asks a child some questions in geometry, with reference to measuring a square; his answers are such as a child would make, and yet the questions are so easy, that while answering them, one by one, he comes to the same point as if he had learned geometry. From whence Socrates would infer that learning is nothing more than recollection; and this topic he explains more accurately in the discourse which he held the very day he died; for he there asserts that, any one, who seeming to be entirely illiterate, is yet able to answer a question well that is proposed to him, does in so doing manifestly show that he is not learning it then, but recollecting it by his memory. Nor is it to be accounted for in any other way, how children 34come to have notions of so many and such impor-

       tant things as are implanted, and, as it were, sealed up, in their minds (which the Greeks call aaaaaaa), unless the soul, before it

       entered the body, had been well stored with knowledge. And as it had no existence at all (for this is the invariable doctrine of Plato, who will not admit anything to have a real existence which has a beginning and an end, and who thinks that that alone does really exist which is of such a character as what he calls aaaaa, and we species), therefore, being shut up in the body, it could not while in the body discover what it knows; but it knew it before, and brought the knowledge with it, so that we are no longer surprised at

       its extensive and multifarious knowledge. Nor does the soul clearly discover its ideas at its first resort to this abode to which it is so

       unaccustomed, and which is in so disturbed a state; but after having refreshed and recollected itself, it then by its memory recovers them; and, therefore, to learn implies nothing more than to recollect. But I am in a particular manner surprised at memory. For what is that faculty by which we remember? what is its force? what its nature? I am not inquiring how great a memory Simonides13 may be said to have had, or Theodectes,14 or that Cineas15 who was sent to Rome as ambassador from Pyrrhus; or, in more modern times, Charmadas;16 or, very lately, Metrodorus17 35the Scepsian, or our own contemporary Hortensius18: I am speaking of ordinary memory, and especially of those men who are employed in any important study or art, the great capacity of whose minds it is hard to estimate, such numbers of things do they remember.

       XXV. 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

       12

       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; 36which, 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.

       XXVI. 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
