of the idea, which to him is the cause of all things (Rep. vi.508 E), 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.
