"The Memorable Thoughts of Socrates" is a collection of Socratic dialogues by Xenophon, a student of Socrates. The lengthiest and most famous of Xenophon's Socratic writings, the Memorabilia is essentially an apologia (defense) of Socrates, differing from both Xenophon's Apology of Socrates to the Jury and Plato's Apology mainly in that the Apologies present Socrates as defending himself before the jury, whereas the former presents Xenophon's own defense of Socrates, offering edifying examples of Socrates' conversations and activities along with occasional commentary from Xenophon.

Xenophon (430 - 354 BC), was a soldier, mercenary, and a contemporary and admirer of Socrates. He is known for his writings on the history of his own times, the 4th century BC, preserving the sayings of Socrates, and the life of ancient Greece.

Xenophon (431-355 BC), son of Gryllus, of the deme Erchia of Athens, was a soldier, mercenary and an admirer of Socrates. He is known for his writings on the history of his own times, the sayings of Socrates, and the life of Greece. He participated in the expedition led by Cyrus the Younger against his older brother, the emperor Artaxerxes II of Persia, in 401 BC. His record of the entire expedition against the Persians and the journey home was titled Anabasis (The Expedition or The March Up Country). He was later exiled from Athens, most likely because he fought under the Spartan king Agesilaus against Athens at Coronea. The Spartans gave him property at Scillus, near Olympia in Elis, where he composed the Anabasis.
