[54] Plutarch, Alkibiadês, c. 10. To a young man like Alkibiadês, thirsting for power and preëminence, a certain measure of rhetorical facility and persuasive power was indispensable. With a view to this acquisition, he frequented the society of various sophistical and rhetorical teachers,[55] Prodikus, Protagoras, and others; but most of all that of Sokratês. His intimacy with Sokratês has become celebrated on many grounds, and is commemorated both by Plato and Xenophon, though unfortunately with less instruction than we could desire. We may readily believe Xenophon, when he tells us that Alkibiadês—like the oligarchical Kritias, of whom we shall have much to say hereafter—was attracted to Sokratês by his unrivalled skill of dialectical conversation, his suggestive influence over the minds of his hearers, in eliciting new thoughts and combinations, his mastery of apposite and homely illustrations, his power of seeing far beforehand the end of a long cross-examination, his ironical affectation of ignorance, whereby the humiliation of opponents was rendered only the more complete, when they were convicted of inconsistency and contradiction out of their own answers. The exhibitions of such ingenuity were in themselves highly interesting, and stimulating to the mental activity of listeners, while the faculty itself was one of peculiar value to those who proposed to take the lead in public debate; with which view both these ambitious young men tried to catch the knack from Sokratês,[56] and to copy his formidable string of interrogations. Both of them doubtless involuntarily respected the poor, self-sufficing, honest, temperate, and brave citizen, in whom this eminent talent resided; especially Alkibiadês, who not only owed his life to the generous valor of Sokratês at Potidæa, but had also learned in that service to admire the iron physical frame of the philosopher in his armor, enduring hunger, cold, and hardship.[57] But we are not to suppose that either of them came to Sokratês with the purpose of hearing and obeying his precepts on matters of duty, or receiving from him a new plan of life. They came partly to gratify an intellectual appetite, partly to acquire a stock of words and ideas, with facility of argumentative handling, suitable for their after-purpose as public speakers. Subjects moral, political, and intellectual, served as the theme sometimes of discourse, sometimes of discussion, in the society of all these sophists, Prodikus and Protagoras not less than Sokratês; for in the Athenian sense of the word, Sokratês was a sophist as well as the others: and to the rich youths of Athens, like Alkibiadês and Kritias, such society was highly useful.[58] It imparted a nobler aim to their ambition, including mental accomplishments as well as political success: it enlarged the range of their understandings, and opened to them as ample a vein of literature and criticism as the age afforded:
