Aeschines of Sphettus (, c. 425 BC – c. 350 BC) or Aeschines Socraticus (), son of Lysanias, of the deme Sphettus of Athens, was a philosopher who in his youth was a follower of Socrates. Historians call him Aeschines Socraticus—"the Socratic Aeschines"—to distinguish him from the more historically influential Athenian orator also named Aeschines. His name is sometimes but now rarely written as Aischines or Æschines.
Aeschines and Socrates
According to Plato, Aeschines of Sphettus was present at the trial and execution of Socrates. We know that after Socrates' death, Aeschines went on to write philosophical dialogues, just as Plato did, in which Socrates was main speaker. Though Aeschines' dialogues have survived only as fragments and quotations by later writers, he was renowned in antiquity for his accurate portrayal of Socratic conversations. According to John Burnet, Aeschines' style of presenting Socratic dialogue was closer to Plato's than Xenophon's. (Some modern scholars believe that Xenophon's writings are inspired almost entirely by Plato's and/or by the influence of other Socratics such as Antisthenes and Hermogenes. On the other hand, there is no good reason to think that Aeschines' writings were not based almost entirely on his own personal recollections of Socrates.)
Socratic dialogues
According to Diogenes Laërtius, Aeschines wrote seven Socratic dialogues: Alcibiades (not to be confused with either Platonic dialogue of the same name) Aspasia Axiochus (not to be confused with the dialogue of the same name erroneously included in the Platonic corpus) Callias Miltiades Rhinon Telauges
Of these, we have the most information about the Alcibiades and the Aspasia, and only a little about the others. The Suda, a Byzantine encyclopedia compiled a dozen centuries later, ascribes to Aeschines several other works called "headless" or "Prefaceless" (akephaloi): Phaidon, Polyainos, Drakon, Eryxias, On Excellence, The Erasistratoi, and The Skythikoi. Few modern scholars believe these other works were written by Aeschines.
The 2nd century AD sophist Publius Aelius Aristides quotes from the Alcibiades at length, preserving for us the largest surviving chunk of Aeschines' written work. Just before World War I, Arthur Hunt recovered from Oxyrhynchus a papyrus (#1608) containing a long, fragmentary passage from this dialogue that had been lost since ancient times. In the dialogue, Socrates converses with a young, ambitious Alcibiades about Themistocles and argues that Alcibiades is unprepared for a career in politics since he has failed to "care for himself" in such a way as to avoid thinking that he knows more than what he actually knows on matters of the most importance. Socrates seems to argue for the view that success is directly proportional to knowledge (though knowledge may not be sufficient for complete success), as opposed to being dependent merely on fortune or divine dispensation, independent of knowledge. Socrates' arguments cause the usually cocky Alcibiades to weep in shame and despair—a result also attested to by Plato in the Symposium. Socrates claims that it is only through loving Alcibiades that he can improve him (by cultivating in him a desire to pursue knowledge?), since Socrates has no knowledge of his own to teach.
Our major sources for the Aspasia are Athenaeus, Plutarch, and Cicero. In the dialogue, Socrates recommends that Callias send his son Hipponicus to Aspasia to learn politics. In the dialogue, Socrates argues, among other things, that women are capable of exactly the same military and political "virtues" as are men, which Socrates proves by referring Callias to the examples of Aspasia herself (who famously advised Pericles), Thargelia of Miletus (a courtesan who supposedly persuaded many Greeks to ally themselves with Xerxes who in turn gave Thargelia part of Thessaly to rule), and the legendary Persian warrior-queen Rhodogyne. (The doctrine is likewise found in Plato's Meno and Republic, and so is confirmed as genuinely Socratic.) A certain Xenophon is also mentioned in the dialogue—Socrates says that Aspasia exhorted this Xenophon and his wife to cultivate knowledge of self as a means to virtue—but this Xenophon may not be the same Xenophon who is more familiar to us as a historian and another author of Socratic memoirs.
In the Telauges, Socrates converses with the Pythagorean ascetic Telauges (a companion of Hermogenes who was Callias' half-brother and a follower of Socrates) and Crito's young son Critobulus. In the dialogue, Socrates criticizes Telauges for his extreme asceticism and Critobulus for his ostentatiousness, apparently in an attempt to argue for a moderate position.
