Apology, Crito, and Phaedo of Socrates

"I then," continued Socrates, "will describe to you one pair of the contraries which I have just now mentioned, both what it is and its mode of production: and do you describe to me the other. I say that one is to sleep, the other to awake; and from sleeping awaking is produced, and from awaking sleeping, and that the modes of their production are, the one to fall asleep, the other to be roused. 44. Have I sufficiently explained this to you or not?"

"Thus, then, we have agreed that the living are produced from the dead, no less than the dead from the living; but, this being the case, there appears to me sufficient proof that the souls of the dead must necessarily exist somewhere, from whence they are again produced."

"See now, O Cebes!" he said, "that we have not agreed on these things improperly, as it appears to me; for if one class of things were not constantly given back in the place of another, revolving, as it were, in a circle, but generation were direct from one thing alone into its opposite, and did not turn round again to the other, or retrace its course, do you know that all things would at length have the same form, be in the same state, and cease to be produced?"

"It is by no means difficult," he replied, "to understand what I mean; if, for instance, there should be such a thing as falling asleep, but no reciprocal waking again produced from a state of sleep, you know that at length all things would show the fable of Endymion to be a jest, and it would be thought nothing at all of, because everything else would be in the same state as he—namely, asleep. And if all things were mingled together, but never separated, that doctrine of Anaxagoras would soon be verified, 'all things would be together.' 46. Likewise, my dear Cebes, if all things that partake of life should die, and after they are dead should remain in this state of death, and not revive again, would it not necessarily follow that at length all things should be dead, and nothing alive? For if living beings are produced from other things, and living beings die, what could prevent their being all absorbed in death?"

"For, Cebes," he continued, "as it seems to me, such undoubtedly is the case, and we have not admitted these things under a delusion, for it is in reality true that there is a reviving again, that the living are produced from the dead, that the souls of the dead exist, and that the condition of the good is better, and of the evil worse."

47. "And, indeed," said Cebes, interrupting him, "according to that doctrine, Socrates, which you are frequently in the habit of advancing, if it is true, that our learning is nothing else than reminiscence, according to this it is surely necessary that we must at some former time have learned what we now remember. But this is impossible, unless our soul existed somewhere before it came into this human form; so that from hence, also, the soul appears to be something immortal."

48. "It is proved," said Cebes, "by one argument, and that a most beautiful one, that men, when questioned (if one questions them properly) of themselves, describe all things as they are, however, if they had not innate knowledge and right reason, they would never be able to do this. Moreover, if one leads them to diagrams, or any thing else of the kind, it is then most clearly apparent that this is the case."

"I do not doubt," said Simmias; "but I require this very thing of which we are speaking, to be reminded; and, indeed, from what Cebes has begun to say, I almost now remember, and am persuaded; nevertheless, however, I should like to hear now how you would attempt to prove it."

49. "Do we, then, admit this also, that when knowledge comes in a certain manner it is reminiscence? But the manner I mean is this: if any one, upon seeing or hearing, or perceiving through the medium of any other sense, some particular thing, should not only know that, but also form an idea of something else, of which the knowledge is not the same, but different, should we not justly say that he remembered that of which he received the idea?"
