 Another source for the historical Socrates is the soldier-historian, Xenophon. Xenophon says explicitly of Socrates, “I was never acquainted with anyone who took greater care to find out what each of his companions knew” (Memorabilia 4.7.1); and Plato corroborates Xenophon’s statement by illustrating throughout his dialogues Socrates’s adjustment of the level and type of his questions to the particular individuals with whom he talked. If it is true that Socrates succeeded in pitching his conversation at the right level for each of his companions, the striking differences between Xenophon’s Socrates and Plato’s is largely explained by the differences between their two personalities. Xenophon was a practical man whose ability to recognize philosophical issues is almost imperceptible, so it is plausible that his Socrates is a practical and helpful advisor. That is the side of Socrates Xenophon experienced. Xenophon’s Socrates differs additionally from Plato’s in offering advice about subjects in which Xenophon was himself experienced, but Socrates was not: moneymaking (Xenophon, Memorabilia 2.7) and estate management (Xenophon, Oeconomicus), suggesting that Xenophon may have entered into the writing of Socratic discourses (as Aristotle labeled the genre, Poetics 1447b11) making the character Socrates a mouthpiece for his own views. His other works mentioning or featuring Socrates are Anabasis, Apology, Hellenica, and Symposium.
