Socrates lived during the time of the transition from the height of the Athenian hegemony to its decline with the defeat by Sparta and its allies in the Peloponnesian War. At a time when Athens sought to stabilize and recover from its humiliating defeat, the Athenian public may have been entertaining doubts about democracy as an efficient form of government. Socrates appears to have been a critic of democracy, and some scholars[who?] interpret his trial as an expression of political infighting.
Claiming loyalty to his city, Socrates clashed with the current course of Athenian politics and society.[15] He praises Sparta, archrival to Athens, directly and indirectly in various dialogues. One of Socrates' purported offenses to the city was his position as a social and moral critic. Rather than upholding a status quo and accepting the development of what he perceived as immorality within his region, Socrates questioned the collective notion of "might makes right" that he felt was common in Greece during this period. Plato refers to Socrates as the "gadfly" of the state (as the gadfly stings the horse into action, so Socrates stung various Athenians), insofar as he irritated some people with considerations of justice and the pursuit of goodness.[16] His attempts to improve the Athenians' sense of justice may have been the cause of his execution.
According to Plato's Apology, Socrates' life as the "gadfly" of Athens began when his friend Chaerephon asked the oracle at Delphi if anyone were wiser than Socrates; the Oracle responded that no-one was wiser. Socrates believed the Oracle's response was a paradox, because he believed he possessed no wisdom whatsoever. He proceeded to test the riddle by approaching men considered wise by the people of Athens—statesmen, poets, and artisans—in order to refute the Oracle's pronouncement. Questioning them, however, Socrates concluded: while each man thought he knew a great deal and was wise, in fact they knew very little and were not wise at all. Socrates realized the Oracle was correct; while so-called wise men thought themselves wise and yet were not, he himself knew he was not wise at all, which, paradoxically, made him the wiser one since he was the only person aware of his own ignorance. Socrates' paradoxical wisdom made the prominent Athenians he publicly questioned look foolish, turning them against him and leading to accusations of wrongdoing. Socrates defended his role as a gadfly until the end: at his trial, when Socrates was asked to propose his own punishment, he suggested a wage paid by the government and free dinners for the rest of his life instead, to finance the time he spent as Athens' benefactor.[17] He was, nevertheless, found guilty of both corrupting the minds of the youth of Athens and of impiety ("not believing in the gods of the state"),[18] and subsequently sentenced to death by drinking a mixture containing poison hemlock.[19][20][21][22]
