disrespectful attitude towards their society. Socrates left no written works; however, his student and friend, Plato, wrote Socratic dialogues, featuring Socrates as the protagonist. As a teacher, competitor intellectuals resented Socrates's elenctic examination method for intellectual inquiry, because its questions threatened their credibility as men of wisdom and virtue. It has sometimes been claimed that Socrates described himself as the "gadfly" of Athens which, like a sluggish horse, needed to be aroused by his "stinging". In the Greek text of his defense given by Plato, Socrates never actually uses that term (viz., "gadfly" [Grk., oîstros]) to describe himself. Rather, his reference is merely allusive, as he (literally) says only that he has attached himself to the City (proskeimenon tē polei) in order to sting it. Nevertheless, he does make the bold claim that he is a god's gift to the Athenians. Socrates's elenctic method was often imitated by the young men of Athens. Association with Alcibiades and the Thirty Tyrants Alcibiades was an Athenian general who had been the main proponent of the disastrous Sicilian Expedition during the Peloponnesian Wars, where virtually the entire Athenian invading force of more than 50,000 soldiers and non-combatants (e.g., the rowers of the Triremes) was killed or captured and enslaved. He was a student and close friend of Socrates, and his messmate during the siege of Potidaea (433–429 BC). Socrates remained Alcibiades's close friend, admirer, and mentor for about five or six years. During his career, Alcibiades famously defected to Sparta, arch-enemy of Athens, after being summoned to trial, then to Persia after being caught in an affair with the wife of his benefactor (the King of Sparta). He then defected back to Athens after successfully persuading the Athenians that Persia would come to their aid against Sparta (though Persia had no intention of doing so). Finally driven out of Athens after the defeat of the Battle of Notium against Sparta, Alcibiades was assassinated in Phrygia in 400 BC by his Spartan enemies. Another possible source of resentment was the political views that he and his associates were thought to have embraced. Critias, who appears in two of Plato's Socratic dialogues, was a leader of the Thirty Tyrants (the ruthless oligarchic regime that ruled Athens, as puppets of Sparta and backed by Spartan troops, for eight months in 404–403 BC until they were overthrown). Several of the Thirty had been students of Socrates, but
