There is no criterion of the date of the Symposium, except that which is furnished by the allusion to the division of Arcadia after the destruction of Mantinea. This took place in the year B.C. 384, which is the forty-fourth year of Plato's life. The Symposium cannot therefore be regarded as a youthful work. As Mantinea was restored in the year 369, the composition of the Dialogue will probably fall between 384 and 369. Whether the recollection of the event is more likely to have been renewed at the destruction or restoration of the city, rather than at some intermediate period, is a consideration not worth raising.
The Symposium is connected with the Phaedrus both in style and subject; they are the only Dialogues of Plato in which the theme of love is discussed at length. In both of them philosophy is regarded as a sort of enthusiasm or madness; Socrates is himself 'a prophet new inspired' with Bacchanalian revelry, which, like his philosophy, he characteristically pretends to have derived not from himself but from others. The Phaedo also presents some points of comparison with the Symposium. For there, too, philosophy might be described as 'dying for love;' and there are not wanting many touches of humour and fancy, which remind us of the Symposium. But while the Phaedo and Phaedrus look backwards and forwards to past and future states of existence, in the Symposium there is no break between this world and another; and we rise from one to the other by a regular series of steps or stages, proceeding from the particulars of sense to the universal of reason, and from one universal to many, which are finally reunited in a single science (compare Rep.). At first immortality means only the succession of existences; even knowledge comes and goes. Then follows, in the language of the mysteries, a higher and a higher degree of initiation; at last we arrive at the perfect vision of beauty, not relative or changing, but eternal and absolute; not bounded by this world, or in or out of this world, but an aspect of the divine, extending over all things, and having no limit of space or time: this is the highest knowledge of which the human mind is capable. Plato does not go on to ask whether the individual is absorbed in the sea of light and beauty or retains his personality. Enough for him to have attained the true beauty or good, without enquiring precisely into the relation in which human beings stood to it. That the soul has such a reach of thought, and is capable of partaking of the eternal nature, seems to imply that she too is eternal (compare Phaedrus). But Plato does not distinguish the eternal in man from the eternal in the world or in God. He is willing to rest in the contemplation of the idea, which to him is the cause of all things (Rep.), and has no strength to go further.
The Symposium of Xenophon, in which Socrates describes himself as a pander, and also discourses of the difference between sensual and sentimental love, likewise offers several interesting points of comparison. But the suspicion which hangs over other writings of Xenophon, and the numerous minute references to the Phaedrus and Symposium, as well as to some of the other writings of Plato, throw a doubt on the genuineness of the work. The Symposium of Xenophon, if written by him at all, would certainly show that he wrote against Plato, and was acquainted with his works. Of this hostility there is no trace in the Memorabilia. Such a rivalry is more characteristic of an imitator than of an original writer. The (so-called) Symposium of Xenophon may therefore have no more title to be regarded as genuine than the confessedly spurious Apology.
There are no means of determining the relative order in time of the Phaedrus, Symposium, Phaedo. The order which has been adopted in this translation rests on no other principle than the desire to bring together in a series the memorials of the life of Socrates.
SYMPOSIUM
PERSONS OF THE DIALOGUE: Apollodorus, who repeats to his companion the dialogue which he had heard from Aristodemus, and had already once narrated to Glaucon. Phaedrus, Pausanias, Eryximachus, Aristophanes, Agathon, Socrates, Alcibiades, A Troop of Revellers.
SCENE: The House of Agathon.
Concerning the things about which you ask to be informed I believe that I am not ill-prepared with an answer. For the day before yesterday I was coming from my own home at Phalerum to the city, and one of my acquaintance, who had caught a sight of me from behind, calling out playfully in the distance, said: Apollodorus, O thou Phalerian (Probably a play of words on (Greek), 'bald-headed.') man, halt! So I did as I was bid; and then he said, I was looking for you, Apollodorus, only just now, that I might ask you about the speeches in praise of love, which were delivered by Socrates, Alcibiades, and others, at Agathon's supper. Phoenix, the son of Philip, told another person who told me of them; his narrative was very indistinct, but he said that you knew, and I wish that you would give me an account of them. Who, if not you, should be the reporter of the words of your friend? And first tell me, he said, were you present at this meeting?
Your informant, Glaucon, I said, must have been very indistinct indeed, if you imagine that the occasion was recent; or that I could have been of the party.
