[In Book 10 of his Republic, Plato has Socrates tell the story of the vision of Er, an allegory concerning the fate of human souls after death and the way in which their next life on earth is determined. The following is the Jowett translation (§§ 614-621). -- Ed.]
I will tell you a tale; not one of the tales which Odysseus tells to the hero Alcinous, yet this too is a tale of a hero, Er the son of Armenius, a Pamphylian by birth. He was slain in battle, and ten days afterwards, when the bodies of the dead were taken up already in a state of corruption, his body was found unaffected by decay, and carried away home to be buried. And on the twelfth day, as he was lying on the funeral pile, he returned to life and told them what he had seen in the other world. He said that when his soul left the body he went on a journey with a great company, and that they came to a mysterious place at which there were two openings in the earth; they were near together, and over against them were two other openings in the heaven above. In the intermediate space there were judges seated, who commanded the just, after they had given judgment on them and had bound their sentences in front of them, to ascend by the heavenly way on the right hand; and in like manner the unjust were bidden by them to descend by the lower way on the left hand; these also bore the symbols of their deeds, but fastened on their backs. He drew near, and they told him that he was to be the messenger who would carry the report of the other world to men, and they bade him hear and see all that was to be heard and seen in that place.
Then he beheld and saw on one side the souls departing at either opening of heaven and earth when sentence had been given on them; and at the two other openings other souls, some ascending out of the earth dusty and worn with travel, some descending out of heaven clean and bright. And arriving ever and anon they seemed to have come from a long journey, and they went forth with gladness into the meadow, where they encamped as at a festival; and those who knew one another embraced and conversed, the souls which came from earth curiously inquiring about the things above, and the souls which came from heaven about the things beneath. And they told one another of what had happened by the way, those from below weeping and sorrowing at the remembrance of the things which they had endured and seen in their journey beneath the earth (now the journey lasted a thousand years), while those from above were describing heavenly delights and visions of inconceivable beauty.
The story, Glaucon, would take too long to tell; but the sum was this: He said that for every wrong which they had done to any one they suffered tenfold; or once in a hundred years -- such being reckoned to be the length of man's life, and the penalty being thus paid ten times in a thousand years. If, for example, there were any who had been the cause of many deaths, or had betrayed or enslaved cities or armies, or been guilty of any other evil behavior, for each and all of their offenses they received punishment ten times over, and the rewards of beneficence and justice and holiness were in the same proportion. . . .
Now when the spirits which were in the meadow had tarried seven days, on the eighth they were obliged to proceed on their journey, and, on the fourth day after, he said that they came to a place where they could see from above a line of light, straight as a column, extending right through the whole heaven and through the earth, in color resembling the rainbow, only brighter and purer; another day's journey brought them to the place, and there, in the midst of the light, they saw the ends of the chains of heaven let down from above: for this light is the belt of heaven, and holds together the circle of the universe. From these ends is extended the spindle of Necessity, on which all the revolutions turn. . . .
Now the whole spindle has the same motion; but, as the whole revolves in one direction, the seven inner circles move slowly in the other, . . . The spindle turns on the knees of Necessity; and on the upper surface of each circle is a siren, who goes round with them, hymning a single tone or note. The eight together form one harmony; and round about, at equal intervals, there is another band, three in number, each sitting upon her throne: these are the Fates, daughters of Necessity, who are clothed in white robes and have chaplets upon their heads, Lachesis and Clotho and Atropos, who accompany with their voices the harmony of the sirens -- Lachesis singing of the Past, Clotho of the Present, Atropos of the Future; Clotho from time to time assisting with a touch of her right hand the revolution of the outer circle of the whorl or spindle, and Atropos with her left hand touching and guiding the inner ones, and Lachesis laying hold of either in turn, first with one hand and then with the other.
When Er and the spirits arrived, their duty was to go at once to Lachesis; but first of all there came a prophet who arranged them in order; then he took from the knees of Lachesis lots and samples of lives, and having mounted a high pulpit, spoke as follows:
"Hear the word of Lachesis, the daughter of Necessity. Mortal souls, behold a new cycle of life and mortality. Your genius will not be allotted to you, but you will choose your genius; and let him who draws the first lot have the first choice, and the life which he chooses shall be his destiny. Virtue is free, and as a man honors or dishonors her he will have more or less of her; the responsibility is with the chooser -- Theos is justified."
When the Interpreter had thus spoken he scattered lots indifferently among them all, and each of them took up the lot which fell near him, all but Er himself (he was not allowed), and each as he took his lot perceived the number which he had obtained. Then the Interpreter placed on the ground before them the samples of lives; and there were many more lives than the souls present, and they were of all sorts. . . . There were tyrannies among them, some lasting out the tyrant's life, others which broke off in the middle and came to an end in poverty and exile and beggary; and there were lives of famous men, some who were famous for their form and beauty as well as for their strength and success in games, or, again, for their birth and the qualities of their ancestors; and some who were the reverse of famous for the opposite qualities. . . . There was every other quality, and they all mingled with one another, and also with elements of wealth and poverty, and disease and health; and there were mean [intermediate] states also.
And here, my dear Glaucon, is the supreme peril of our human state; and therefore the utmost care should be taken. Let each one of us leave every other kind of knowledge and seek and follow one thing only, if peradventure he may be able to learn and may find some one who will make him able to learn and discern between good and evil, and so to choose always and everywhere the better life as he has opportunity. He should consider the bearing of all these things which have been mentioned severally and collectively upon virtue; he should know what the effect of beauty is when combined with poverty or wealth in a particular soul, and what are the good and evil consequences of noble and humble birth, of private and public station, of strength and weakness, of cleverness and dullness, and of all the natural and acquired gifts of the soul, and the operation of them when conjoined. He will then look at the nature of the soul, and from the consideration of all these qualities he will be able to determine which is the better and which is the worse. And so he will choose, giving the name of evil to the life which will make his soul more unjust, and good to the life which will make his soul more just; all else he will disregard. For we have seen and know that this is the best choice both in life and after death. A man must take with him into the world below an adamantine faith in truth and right, that there too he may be undazzled by the desire of wealth or the other allurements of evil, lest, coming upon tyrannies and similar villainies, he do irremediable wrongs to others and suffer yet worse himself; but let him know how to choose the middle way and avoid the extremes on either side, as far as possible, not only in this life but in all that which is to come. For this is the way of happiness.
And according to the report of the messenger from the other world this was what the prophet said at the time:
"Even for the last comer, if he chooses wisely and will live diligently, there is appointed a happy and not undesirable existence. Let not him who chooses first be careless, and let not the last despair."
And when he had spoken, he who had the first choice came forward and in a moment chose the greatest tyranny; his mind having been darkened by folly and sensuality, he had not thought out the whole matter before he chose, and did not at first sight perceive that he was fated, among other evils, to devour his own children. But when he had time to reflect, and saw what was in the lot, he began to beat his breast and lament over his choice, forgetting the proclamation of the prophet; for, instead of throwing the blame of his misfortune on himself, he accused chance and the gods, and everything rather than himself. Now he was one of those who came from heaven, and in a former life had dwelt in a well-ordered State, but his virtue was a matter of habit only, and he had no philosophy. . . .
Most curious, he said, was the spectacle -- sad and laughable and strange; for the choice of the souls was in most cases based on their experience of a previous life. . . . There came also the soul of Odysseus having yet to make a choice, and his lot happened to be the last of them all. Now the recollection of former toils had disenchanted him of ambition, and he went about for a considerable time in search of the life of a private man who had no cares; he had some difficulty in finding this, which was lying about and had been neglected by everybody else; and when he saw it, he said that he would have done the same had his lot been first instead of last, and that he was delighted to have it. . . .
All the souls had now chosen their lives, and they went in the order of their choice to Lachesis [the Past], who sent with them the genius whom they had severally chosen, to be the guardian of their lives and the fulfiller of the[ir] choice: this genius led the souls first to Clotho [the Present], and drew them within the revolution of the spindle impelled by her hand, thus ratifying the destiny of each; and then, when they were fastened to this, carried them to Atropos [the Future], who spun the threads and made them irreversible, whence without turning round they passed beneath the throne of Necessity. And when they had all passed, they marched on in a scorching heat to the plain of Forgetfulness [Lethe], which was a barren waste destitute of trees and verdure; and then towards evening they encamped by the river of Unmindfulness, whose water no vessel can hold; of this they were all obliged to drink a certain quantity, and those who were not saved by wisdom drank more than was necessary; and each one as he drank forgot all things.
Now after they had gone to rest, about the middle of the night there was a thunderstorm and earthquake, and then in an instant they were driven upwards in all manner of ways to their birth, like stars shooting. He [Er] himself was hindered from drinking the water. But in what manner or by what means he returned to the body he could not say; only, in the morning, awaking suddenly, he found himself lying on the pyre.
And thus, Glaucon, the tale has been saved and has not perished, and will save us if we are obedient to the word spoken; and we shall pass safely over the river of Forgetfulness and our soul will not be defiled. Wherefore my counsel is that we hold fast ever to the heavenly way and follow after justice and virtue always, considering that the soul is immortal and able to endure every sort of good and every sort of evil.
Thus shall we live dear to one another and to the gods, both while remaining here and when, like conquerors in the games who go round to gather gifts, we receive our reward. And it shall be well with us both in this life and in the pilgrimage of a thousand years which we have been describing.
