Fourthly, The Phædrus and Symposion have, both of them in common, the theory of Eros as the indispensable, initiatory, stimulus to philosophy. The spectacle of a beautiful youth is considered necessary to set light to various elements in the mind, which would otherwise remain dormant and never burn: it enables the pregnant and capable mind to bring forth what it has within and to put out its hidden strength. But if we look to the Phædon, Theætêtus, Sophistês, or Republic, we shall not find Eros invoked for any such function. The Republic describes an elaborate scheme for generating and developing the philosophic capacity: but Eros plays no part in it. In the Theætêtus, the young man so named is announced as having a pregnant mind requiring to be disburthened, and great capacity which needs foreign aid to develop it: the service needed is rendered by Sokrates, who possesses an obstetric patent, and a marvellous faculty of cross-examination. Yet instead of any auxiliary stimulus arising from personal beauty, the personal ugliness of both persons in the dialogue is emphatically signified. I note these peculiarities, partly of the Symposion, partly of the Phædrus along with it--to illustrate the varying points of view which the reader must expect to meet in travelling through the numerous Platonic dialogues. [Side-note: Concluding scene and speech of Alkibiades in the Symposion--Behaviour of Sokrates to Alkibiades and other handsome youths.] In the strange scene with which the Symposion is wound up, the main purpose of the dialogue is still farther worked out. The spirit and ethical character of Eros Philosophus, after having been depicted in general terms by Diotima, are specially exemplified in the personal history of Sokrates, as recounted and appreciated by Alkibiades. That handsome, high-born, and insolent youth, being in a complete state of intoxication, breaks in unexpectedly upon the company, all of whom are as yet sober: he enacts the part of a drunken man both in speech and action, which is described with a vivacity that would do credit to any dramatist. His presence is the signal for beginning to drink hard, and he especially challenges Sokrates to drink off, after him, as much wine as will fill the large water-vessel serving as cooler; which challenge Sokrates forthwith accepts and executes, without being the least affected by it. Alkibiades instead of following the example of the others by delivering an encomium on Eros, undertakes to deliver one upon Sokrates. He proceeds to depict Sokrates as the votary of Eros Philosophus, wrapped up in the contemplation of beautiful youths, and employing his whole time in colloquy with them--yet as never losing his own self-command, even while acquiring a magical ascendency over these companions.[40] The abnormal exterior of Sokrates, resembling that of a Satyr, though concealing the image of a God within--the eccentric pungency of his conversation, blending banter with seriousness,
