The characters--of Phaedrus, who has been the cause of more
philosophical discussions than any other man, with the exception of
Simmias the Theban (Phaedrus); of Aristophanes, who disguises under
comic imagery a serious purpose; of Agathon, who in later life is
satirized by Aristophanes in the Thesmophoriazusae, for his effeminate
manners and the feeble rhythms of his verse; of Alcibiades, who is the
same strange contrast of great powers and great vices, which meets us
in history--are drawn to the life; and we may suppose the less-known
characters of Pausanias and Eryximachus to be also true to the
traditional recollection of them (compare Phaedr., Protag.; and compare
Sympos. with Phaedr.). We may also remark that Aristodemus is called
'the little' in Xenophon's Memorabilia (compare Symp.).
The speeches have been said to follow each other in pairs: Phaedrus and
Pausanias being the ethical, Eryximachus and Aristophanes the physical
speakers, while in Agathon and Socrates poetry and philosophy blend
together. The speech of Phaedrus is also described as the mythological,
that of Pausanias as the political, that of Eryximachus as the
scientific, that of Aristophanes as the artistic (!), that of Socrates
as the philosophical. But these and similar distinctions are not found
in Plato;--they are the points of view of his critics, and seem to
impede rather than to assist us in understanding him.
When the turn of Socrates comes round he cannot be allowed to disturb
the arrangement made at first. With the leave of Phaedrus he asks a few
questions, and then he throws his argument into the form of a speech
(compare Gorg., Protag.). But his speech is really the narrative of a
dialogue between himself and Diotima. And as at a banquet good manners
would not allow him to win a victory either over his host or any of
the guests, the superiority which he gains over Agathon is ingeniously
represented as having been already gained over himself by her. The
artifice has the further advantage of maintaining his accustomed
profession of ignorance (compare Menex.). Even his knowledge of the
mysteries of love, to which he lays claim here and elsewhere (Lys.), is
given by Diotima.
