Cicero's Tusculan Disputations

XIV. But the greatest proof of all is, that nature herself gives a silent judgment in favor of the immortality of the soul, inasmuch as all are anxious, and that to a great degree, about the things which concern futurity:

 
One plants what future ages shall enjoy,
 

as Statius saith in his Synephebi. What is his object in doing so, except that he is interested in posterity? Shall the industrious husbandman, then, plant trees the fruit of which he shall never see? And shall not the great man found laws, institutions, and a republic? What does the procreation of children imply, and our care to continue our names, and our adoptions, and our scrupulous exactness in drawing up wills, and the inscriptions on monuments, and panegyrics, but that our thoughts run on futurity? There is no doubt but a judgment may be formed of nature in general, from looking at each nature in its most perfect specimens; and what is a more perfect specimen of a man than those are who look on themselves as born for the assistance, the protection, and the preservation of others? Hercules has gone to heaven; he never would have gone thither had he not, while among men, made that road for himself. These things are of old date, and have, besides, the sanction of universal religion.

XV. What will you say? What do you imagine that so many and such great men of our republic, who have sacrificed their lives for its good, expected? Do you believe that they thought that their names should not continue beyond their lives? None ever encountered death for their country but under a firm persuasion of immortality! Themistocles might have lived at his ease; so might Epaminondas; and, not to look abroad and among the ancients 23for instances, so might I myself. But, somehow or other there clings to our minds a certain presage of future ages; and this both exists most firmly, and appears most clearly, in men of the loftiest genius and greatest souls. Take away this, and who would be so mad as to spend his life amidst toils and dangers? I speak of those in power. What are the poet’s views but to be ennobled after death? What else is the object of these lines,

 
Behold old Ennius here, who erst
Thy fathers’ great exploits rehearsed?
 

He is challenging the reward of glory from those men whose ancestors he himself had ennobled by his poetry. And in the same spirit he says, in another passage,

 
Let none with tears my funeral grace, for I
Claim from my works an immortality.
 

Why do I mention poets? The very mechanics are desirous of fame after death. Why did Phidias include a likeness of himself in the shield of Minerva, when he was not allowed to inscribe his name on it? What do our philosophers think on the subject? Do not they put their names to those very books which they write on the contempt of glory? If, then, universal consent is the voice of nature, and if it is the general opinion everywhere that those who have quitted this life are still interested in something, we also must subscribe to that opinion. And if we think that men of the greatest abilities and virtues see most clearly into the power of nature, because they themselves are her most perfect work, it is very probable that, as every great man is especially anxious to benefit posterity, there is something of which he himself will be sensible after death.

XVI. But as we are led by nature to think there are Gods, and as we discover, by reason, of what description they are, so, by the consent of all nations, we are induced to believe that our souls survive; but where their habitation is, and of what character they eventually are, must be learned from reason. The want of any certain reason on which to argue has given rise to the idea of the shades below, and to those fears which you seem, not without 24reason, to despise; for as our bodies fall to the ground, and are covered with earth (humus), from whence we derive the expression to be interred (humari), that has occasioned men to imagine that the dead continue, during the remainder of their existence, under ground; which opinion has drawn after it many errors, which the poets have increased; for the theatre, being frequented by a large crowd, among which are women and children, is wont to be greatly affected on hearing such pompous verses as these,

 
Lo! here I am, who scarce could gain this place,
Through stony mountains and a dreary waste;
Through cliffs, whose sharpen’d stones tremendous hung,
Where dreadful darkness spread itself around.
 

And the error prevailed so much, though indeed at present it seems to me to be removed, that although men knew that the bodies of the dead had been burned, yet they conceived such things to be done in the infernal regions as could not be executed or imagined without a body; for they could not conceive how disembodied souls could exist; and, therefore, they looked out for some shape or figure. This was the origin of all that account of the dead in Homer. This was the idea that caused my friend Appius to frame his Necromancy; and this is how there got about that idea of the lake of Avernus, in my neighborhood,

 
From whence the souls of undistinguish’d shape,
Clad in thick shade, rush from the open gate
Of Acheron, vain phantoms of the dead.
 

And they must needs have these appearances speak, which is not possible without a tongue, and a palate, and jaws, and without the help of lungs and sides, and without some shape or figure; for they could see nothing by their mind alone—they referred all to their eyes. To withdraw the mind from sensual objects, and abstract our thoughts from what we are accustomed to, is an attribute of great genius. I am persuaded, indeed, that there were many such men in former ages; but Pherecydes⁸ the Syrian is the 25first on record who said that the souls of men were immortal, and he was a philosopher of great antiquity, in the reign of my namesake Tullius. His disciple Pythagoras greatly confirmed this opinion, who came into Italy in the reign of Tarquin the Proud; and all that country which is called Great Greece was occupied by his school, and he himself was held in high honor, and had the greatest authority; and the Pythagorean sect was for many ages after in such great credit, that all learning was believed to be confined to that name.

XVII. But I return to the ancients. They scarcely ever gave any reason for their opinion but what could be explained by numbers or definitions. It is reported of Plato that he came into Italy to make himself acquainted with the Pythagoreans; and that when there, among others, he made an acquaintance with Archytas⁹ and Timæus,¹⁰ and learned from them all the tenets of the Pythagoreans; and that he not only was of the same opinion with Pythagoras concerning the immortality of the soul, but that he also brought reasons in support of it; which, if you have nothing to say against it, I will pass over, and say no more at present about all this hope of immortality.

A. What, will you leave me when you have raised my expectations so high? I had rather, so help me Hercules! be mistaken with Plato, whom I know how much you esteem, and whom I admire myself, from what you say of him, than be in the right with those others.

26M. I commend you; for, indeed, I could myself willingly be mistaken in his company. Do we, then, doubt, as we do in other cases (though I think here is very little room for doubt in this case, for the mathematicians prove the facts to us), that the earth is placed in the midst of the world, being, as it were, a sort of point, which they call a κέντρον, surrounded by the whole heavens; and that such is the nature of the four principles which are the generating causes of all things, that they have equally divided among them the constituents of all bodies; moreover, that earthy and humid bodies are carried at equal angles by their own weight and ponderosity into the earth and sea; that the other two parts consist, one of fire, and the other of air? As the two former are carried by their gravity and weight into the middle region of the world, so these, on the other hand, ascend by right lines into the celestial regions, either because, owing to their intrinsic nature, they are always endeavoring to reach the highest place, or else because lighter bodies are naturally repelled by heavier; and as this is notoriously the case, it must evidently follow that souls, when once they have departed from the body, whether they are animal (by which term I mean capable of breathing) or of the nature of fire, must mount upward. But if the soul is some number, as some people assert, speaking with more subtlety than clearness, or if it is that fifth nature, for which it would be more correct to say that we have not given a name to than that we do not correctly understand it—still it is too pure and perfect not to go to a great distance from the earth. Something of this sort, then, we must believe the soul to be, that we may not commit the folly of thinking that so active a principle lies immerged in the heart or brain; or, as Empedocles would have it, in the blood.

XVIII. We will pass over Dicæarchus,¹¹ with his contemporary and fellow-disciple Aristoxenus,¹² both indeed 27men of learning. One of them seems never even to have been affected with grief, as he could not perceive that he had a soul; while the other is so pleased with his musical compositions that he endeavors to show an analogy betwixt them and souls. Now, we may understand harmony to arise from the intervals of sounds, whose various compositions occasion many harmonies; but I do not see how a disposition of members, and the figure of a body without a soul, can occasion harmony. He had better, learned as he is, leave these speculations to his master Aristotle, and follow his own trade as a musician. Good advice is given him in that Greek proverb,

 
Apply your talents where you best are skill’d.
 

I will have nothing at all to do with that fortuitous concourse of individual light and round bodies, notwithstanding Democritus insists on their being warm and having breath, that is to say, life. But this soul, which is compounded of either of the four principles from which we assert that all things are derived, is of inflamed air, as seems particularly to have been the opinion of Panætius, and must necessarily mount upward; for air and fire have no tendency downward, but always ascend; so should they be dissipated that must be at some distance from the earth; but should they remain, and preserve their original state, it is clearer still that they must be carried heavenward, and this gross and concrete air, which is nearest the earth, must be divided and broken by them; for the soul is warmer, or rather hotter, than that air, which I just now called gross and concrete: and this may be made evident from this consideration—that our bodies, being compounded of the earthy class of principles, grow warm by the heat of the soul.

XIX. We may add, that the soul can the more easily escape from this air, which I have often named, and break 28through it, because nothing is swifter than the soul; no swiftness is comparable to the swiftness of the soul, which, should it remain uncorrupt and without alteration, must necessarily be carried on with such velocity as to penetrate and divide all this atmosphere, where clouds, and rain, and winds are formed, which, in consequence of the exhalations from the earth, is moist and dark: but, when the soul has once got above this region, and falls in with, and recognizes, a nature like its own, it then rests upon fires composed of a combination of thin air and a moderate solar heat, and does not aim at any higher flight; for then, after it has attained a lightness and heat resembling its own, it moves no more, but remains steady, being balanced, as it were, between two equal weights. That, then, is its natural seat where it has penetrated to something like itself, and where, wanting nothing further, it may be supported and maintained by the same aliment which nourishes and maintains the stars.

Now, as we are usually incited to all sorts of desires by the stimulus of the body, and the more so as we endeavor to rival those who are in possession of what we long for, we shall certainly be happy when, being emancipated from that body, we at the same time get rid of these desires and this rivalry. And that which we do at present, when, dismissing all other cares, we curiously examine and look into anything, we shall then do with greater freedom; and we shall employ ourselves entirely in the contemplation and examination of things; because there is naturally in our minds a certain insatiable desire to know the truth, and the very region itself where we shall arrive, as it gives us a more intuitive and easy knowledge of celestial things, will raise our desires after knowledge. For it was this beauty of the heavens, as seen even here upon earth, which gave birth to that national and hereditary philosophy (as Theophrastus calls it), which was thus excited to a desire of knowledge. But those persons will in a most especial degree enjoy this philosophy, who, while they were only inhabitants of this world and enveloped in darkness, were still desirous of looking into these things with the eye of their mind.

XX. For if those men now think that they have attained 29something who have seen the mouth of the Pontus, and those straits which were passed by the ship called Argo, because,

 
From Argos she did chosen men convey,
Bound to fetch back the Golden Fleece, their prey;
 

or those who have seen the straits of the ocean,

 
Where the swift waves divide the neighboring shores
Of Europe, and of Afric;
 

what kind of sight do you imagine that will be when the whole earth is laid open to our view? and that, too, not only in its position, form, and boundaries, nor those parts of it only which are habitable, but those also that lie uncultivated, through the extremities of heat and cold to which they are exposed; for not even now is it with our eyes that we view what we see, for the body itself has no senses; but (as the naturalists, ay, and even the physicians assure us, who have opened our bodies, and examined them) there are certain perforated channels from the seat of the soul to the eyes, ears, and nose; so that frequently, when either prevented by meditation, or the force of some bodily disorder, we neither hear nor see, though our eyes and ears are open and in good condition; so that we may easily apprehend that it is the soul itself which sees and hears, and not those parts which are, as it were, but windows to the soul, by means of which, however, she can perceive nothing, unless she is on the spot, and exerts herself. How shall we account for the fact that by the same power of thinking we comprehend the most different things—as color, taste, heat, smell, and sound—which the soul could never know by her five messengers, unless every thing were referred to her, and she were the sole judge of all? And we shall certainly discover these things in a more clear and perfect degree when the soul is disengaged from the body, and has arrived at that goal to which nature leads her; for at present, notwithstanding nature has contrived, with the greatest skill, those channels which lead from the body to the soul, yet are they, in some way or other, stopped up with earthy and concrete bodies; but when we shall be nothing but soul, then nothing will interfere 30to prevent our seeing everything in its real substance and in its true character.

XXI. It is true, I might expatiate, did the subject require it, on the many and various objects with which the soul will be entertained in those heavenly regions; when I reflect on which, I am apt to wonder at the boldness of some philosophers, who are so struck with admiration at the knowledge of nature as to thank, in an exulting manner, the first inventor and teacher of natural philosophy, and to reverence him as a God; for they declare that they have been delivered by his means from the greatest tyrants, a perpetual terror, and a fear that molested them by night and day. What is this dread—this fear? What old woman is there so weak as to fear these things, which you, forsooth, had you not been acquainted with natural philosophy, would stand in awe of?

 
The hallow’d roofs of Acheron, the dread
Of Orcus, the pale regions of the dead.
 

And does it become a philosopher to boast that he is not afraid of these things, and that he has discovered them to be false? And from this we may perceive how acute these men were by nature, who, if they had been left without any instruction, would have believed in these things. But now they have certainly made a very fine acquisition in learning that when the day of their death arrives, they will perish entirely. And if that really is the case—for I say nothing either way—what is there agreeable or glorious in it? Not that I see any reason why the opinion of Pythagoras and Plato may not be true; but even although Plato were to have assigned no reason for his opinion (observe how much I esteem the man), the weight of his authority would have borne me down; but he has brought so many reasons, that he appears to me to have endeavored to convince others, and certainly to have convinced himself.

XXII. But there are many who labor on the other side of the question, and condemn souls to death, as if they were criminals capitally convicted; nor have they any other reason to allege why the immortality of the soul appears to them to be incredible, except that they are not 31able to conceive what sort of thing the soul can be when disentangled from the body; just as if they could really form a correct idea as to what sort of thing it is, even when it is in the body; what its form, and size, and abode are; so that were they able to have a full view of all that is now hidden from them in a living body, they have no idea whether the soul would be discernible by them, or whether it is of so fine a texture that it would escape their sight. Let those consider this, who say that they are unable to form any idea of the soul without the body, and then they will see whether they can form any adequate idea of what it is when it is in the body. For my own part, when I reflect on the nature of the soul, it appears to me a far more perplexing and obscure question to determine what is its character while it is in the body—a place which, as it were, does not belong to it—than to imagine what it is when it leaves it, and has arrived at the free æther, which is, if I may so say, its proper, its own habitation. For unless we are to say that we cannot apprehend the character or nature of anything which we have never seen, we certainly may be able to form some notion of God, and of the divine soul when released from the body. Dicæarchus, indeed, and Aristoxenus, because it was hard to understand the existence and substance and nature of the soul, asserted that there was no such thing as a soul at all. It is, indeed, the most difficult thing imaginable to discern the soul by the soul. And this, doubtless, is the meaning of the precept of Apollo, which advises every one to know himself. For I do not apprehend the meaning of the God to have been that we should understand our members, our stature, and form; for we are not merely bodies; nor, when I say these things to you, am I addressing myself to your body: when, therefore, he says, “Know yourself,” he says this, “Inform yourself of the nature of your soul;” for the body is but a kind of vessel, or receptacle of the soul, and whatever your soul does is your own act. To know the soul, then, unless it had been divine, would not have been a precept of such excellent wisdom as to be attributed to a God; but even though the soul should not know of what nature itself is, will you say that it does not even perceive that 32it exists at all, or that it has motion? On which is founded that reason of Plato’s, which is explained by Socrates in the Phædrus, and inserted by me, in my sixth book of the Republic.

XXIII. “That which is always moved is eternal; but that which gives motion to something else, and is moved itself by some external cause, when that motion ceases, 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 important things as are implanted, and, as it were, sealed up, in their minds (which the Greeks call ἔννοιαι), 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 εἴδεα, 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 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 Timæus, 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 fruitful sentences, can flow thus without something beyond mere human power. But as to philosophy, that is the parent of all the arts: what can we call that but, as Plato says, a gift, or, as I express it, an invention, of the Gods? This it was which first taught us the worship of the Gods; and then led us on to justice, which arises from the human race being formed into society; and after that 37it imbued us with modesty and elevation of soul. This it was which dispersed darkness from our souls, as it is dispelled from our eyes, enabling us to see all things that are above or below, the beginning, end, and middle of everything. I am convinced entirely that that which could effect so many and such great things must be a divine power. For what is memory of words and circumstances? What, too, is invention? Surely they are things than which nothing greater can be conceived in a God! For I do not imagine the Gods to be delighted with nectar and ambrosia, or with Juventas presenting them with a cup; nor do I put any faith in Homer, who says that Ganymede was carried away by the Gods on account of his beauty, in order to give Jupiter his wine. Too weak reasons for doing Laomedon such injury! These were mere inventions of Homer, who gave his Gods the imperfections of men. I would rather that he had given men the perfections of the Gods! those perfections, I mean, of uninterrupted health, wisdom, invention, memory. Therefore the soul (which is, as I say, divine) is, as Euripides more boldly expresses it, a God. And thus, if the divinity be air or fire, the soul of man is the same; for as that celestial nature has nothing earthly or humid about it, in like manner the soul of man is also free from both these qualities: but if it is of that fifth kind of nature, first introduced by Aristotle, then both Gods and souls are of the same.
