XX. You may likewise observe that the same globe of the earth is girt and surrounded with certain zones, whereof those two that are most remote from each other, and lie under the opposite poles of heaven, are congealed with frost; but that one in the middle, which is far the largest, is scorched with the intense heat of the sun. The other two are habitable, one towards the south, the inhabitants of which are your antipodes, with whom you have no connection; the other, towards the north, is that which you inhabit, whereof a very small part, as you may see, falls to your share. For the whole extent of what you see is, as it were, but a little island, narrow at both ends and wide in the middle, which is surrounded by the sea which on earth you call the great Atlantic Ocean, and which, notwithstanding this magnificent name, you see is very insignificant. And even in these cultivated and well-known countries, has yours, or any of our names, ever passed the heights of the Caucasus or the currents of the Ganges? In what other parts to the north or the south, or where the sun rises and sets, will your names ever be heard? And if we leave these out of the question, how small a space is there left for your glory to spread itself abroad; and how long will it remain in the memory of those whose minds are now full of it?

XXI. Besides all this, if the progeny of any future generation should wish to transmit to their posterity the praises of any one of us which they have heard from their forefathers, yet the deluges and combustions of the earth, which must necessarily happen at their destined periods, will prevent our obtaining, not only an eternal, but even a durable glory. And, after all, what does it signify whether those who shall hereafter be born talk of you, when those who have lived before you, whose number was perhaps not less, and whose merit certainly greater, were not so much as acquainted with your name?

XXII. Especially since not one of those who shall hear 464of us is able to retain in his memory the transactions of a single year. The bulk of mankind, indeed, measure their year by the return of the sun, which is only one star. But when all the stars shall have returned to the place whence they set out, and after long periods shall again exhibit the same aspect of the whole heavens, that is what ought properly to be called the revolution of a year, though I scarcely dare attempt to enumerate the vast multitude of ages contained in it. For as the sun in old time was eclipsed, and seemed to be extinguished, at the time when the soul of Romulus penetrated into these eternal mansions, so, when all the constellations and stars shall revert to their primary position, and the sun shall at the same point and time be again eclipsed, then you may consider that the grand year is completed. Be assured, however, that the twentieth part of it is not yet elapsed.

If, then, you wish to elevate your views to the contemplation of this eternal seat of splendor, you will not be satisfied with the praises of your fellow-mortals, nor with any human rewards that your exploits can obtain; but Virtue herself must point out to you the true and only object worthy of your pursuit. Leave to others to speak of you as they may, for speak they will. Their discourses will be confined to the narrow limits of the countries you see, nor will their duration be very extensive; for they will perish like those who utter them, and will be no more remembered by their posterity.

XXIV. When he had ceased to speak in this manner, I said, O Africanus, if indeed the door of heaven is open to those who have deserved well of their country, although, indeed, from my childhood I have always followed yours and my father’s steps, and have not neglected to imitate your glory, still, I will from henceforth strive to follow them more closely.

Follow them, then, said he, and consider your body only, not yourself, as mortal. For it is not your outward form 465which constitutes your being, but your mind; not that substance which is palpable to the senses, but your spiritual nature. Know, then, that you are a God—for a God it must be, which flourishes, and feels, and recollects, and foresees, and governs, regulates and moves the body over which it is set, as the Supreme Ruler does the world which is subject to him. For as that Eternal Being moves whatever is mortal in this world, so the immortal mind of man moves the frail body with which it is connected.

That alone, then, which moves itself can never cease to be moved, because it can never desert itself. Moreover, it must be the source, and origin, and principle of motion in all the rest. There can be nothing prior to a principle, for all things must originate from it; and it cannot itself derive its existence from any other source, for if it did it would no longer be a principle. And if it had no beginning, it can have no end; for a beginning that is put an end to will neither be renewed by any other cause, nor will it produce anything else of itself. All things, therefore, must originate from one source. Thus it follows that motion must have its source in something which is moved by itself, and which can neither have a beginning nor an end. Otherwise all the heavens and all nature must perish, for it is impossible that they can of themselves acquire any power of producing motion in themselves.

XXVI. As, therefore, it is plain that what is moved by itself must be eternal, who will deny that this is the general condition and nature of minds? For as everything is inanimate which is moved by an impulse exterior to itself, so what is animated is moved by an interior impulse of its own; for this is the peculiar nature and power of mind. And if that alone has the power of self-motion, it can neither have had a beginning, nor can it have an end.

Do you, therefore, exercise this mind of yours in the best pursuits. And the best pursuits are those which consist in promoting the good of your country. Such employments will speed the flight of your mind to this its 466proper abode; and its flight will be still more rapid, if, even while it is enclosed in the body, it will look abroad, and disengage itself as much as possible from its bodily dwelling, by the contemplation of things which are external to itself.

This it should do to the utmost of its power. For the minds of those who have given themselves up to the pleasures of the body, paying, as it were, a servile obedience to their lustful impulses, have violated the laws of God and man; and therefore, when they are separated from their bodies, flutter continually round the earth on which they lived, and are not allowed to return to this celestial region till they have been purified by the revolution of many ages.
