"Our souls, therefore, Simmias, existed before they were in a human form, separate from bodies, and possessed intelligence."
[57]. "Unless, Socrates, we receive this knowledge at our birth, for this period yet remains."
"Be it so, my friend. But at what other time do we lose it? for we are not born with it, as we have just now admitted. Do we lose it, then, at the very time in which we receive it? Or can you mention any other time?"
"By no means, Socrates; I was not aware that I was saying nothing to the purpose."
"Does the case then stand thus with us, Simmias?" he proceeded: "If those things which we are continually talking about really exist, the beautiful, the good, and every such essence, and to this we refer all things that come under the senses, as finding it to have a prior existence, and to be our own, and if we compare these things to it, it necessarily follows, that as these exist, so likewise our soul exists even before we are born; but if these do not exist, this discussion will have been undertaken in vain, is it not so? And is there not an equal necessity both that these things should exist, and our souls also, before we are born; and if not the former, neither the latter?"
[58]. "Most assuredly, Socrates," said Simmias, "there appears to me to be the same necessity; and the argument admirably tends to prove that our souls exist before we are born, just as that essence does which you have now mentioned. For I hold nothing so clear to me as this, that all such things most certainly exist, as the beautiful, the good, and all the rest that you just now spoke of; and, so far as I am concerned, the case is sufficiently demonstrated."
"But how does it appear to Cebes?" said Socrates; "for it is necessary to persuade Cebes too."
"He is sufficiently persuaded, I think," said Simmias, "although he is the most pertinacious of men in distrusting arguments. Yet I think he is sufficiently persuaded of this, that our soul existed before we were born. But whether, when we are dead, it will still exist does not appear to me to have been demonstrated, Socrates," he continued; "but that popular doubt, which Cebes just now mentioned, still stands in our way, whether, when a man dies, the soul is not dispersed, and this is the end of its existence. [59]. For what hinders it being born, and formed from some other source, and existing before it came into a human body, and yet, when it has come, and is separated from this body, its then also dying itself, and being destroyed?"
"You say well, Simmias," said Cebes; "for it appears that only one half of what is necessary has been demonstrated—namely, that our soul existed before we were born; but it is necessary to demonstrate further, that when we are dead it will exist no less than before we were born, if the demonstration is to be made complete."
"This has been even now demonstrated, Simmias and Cebes," said Socrates, "if you will only connect this last argument with that which we before assented to, that every thing living is produced from that which is dead. For if the soul exists before, and it is necessary for it when it enters into life, and is born, to be produced from nothing else than death, and from being dead, how is it not necessary for it also to exist after death, since it must needs be produced again? [60]. What you require, then, has been already demonstrated. However, both you and Simmias appear to me as if you wished to sift this argument more thoroughly, and to be afraid, like children, lest, on the soul's departure from the body, the winds should blow it away and disperse it, especially if one should happen to die, not in a calm, but in a violent storm."
