Plato, Phaedo

[86a] divine in the well attuned lyre, but the lyre itself and its strings are bodies, and corporeal and composite and earthy and akin to that which is mortal. Now if someone shatters the lyre or cuts and breaks the strings, what if he should maintain by the same argument you employed, that the harmony could not have perished and must still exist? For there would be no possibility that the lyre and its strings, which are of mortal nature, still exist after the strings are broken, and the harmony, [86b] which is related and akin to the divine and the immortal, perish before that which is mortal. He would say that the harmony must still exist somewhere, and that the wood and the strings must rot away before anything could happen to it. And I fancy, Socrates, that it must have occurred to your own mind that we believe the soul to be something after this fashion; that our body is strung and held together by heat, cold, moisture, dryness, and the like, [86c] and the soul is a mixture and a harmony of these same elements, when they are well and properly mixed. Now if the soul is a harmony, it is clear that when the body is too much relaxed or is too tightly strung by diseases or other ills, the soul must of necessity perish, no matter how divine it is, like other harmonies in sounds and in all the works of artists, and the remains of each body will endure [86d] a long time until they are burnt or decayed. Now what shall we say to this argument, if anyone claims that the soul, being a mixture of the elements of the body, is the first to perish in what is called death?”

Then Socrates, looking keenly at us, as he often used to do, smiled and said: “Simmias raises a fair objection. Now if any of you is readier than I, why does he not reply to him? For he seems to score a good point. However, I think [86e] before replying to him we ought to hear what fault our friend Cebes finds with our argument, that we may take time to consider what to say, and then when we have heard them, we can either agree with them, if they seem to strike the proper note, or, if they do not, we can proceed to argue in defence of our reasoning. Come, Cebes,” said he, “tell us what it was that troubled you.”

“Well, I will tell you,” said Cebes. “The argument seems to me to be just where it was, and to be still open to the objection I made before.
