Socrates was by far one of the most important philosophers. However, he wrote no works of his own; therefore we come to know about Socrates’ life and teachings through his student and friend Plato (427 BCE — 347 BCE). The Apology, which was written by Plato, is undeniably one of the most important writings on Socrates’ speech that he gave at his trial. Socrates was accused of impiety and corrupting the youth. In Plato’s Apology, Socrates repeatedly refers to a single God, and he refused to honour the Greek gods. He was defending himself and his conception of philosophy, however, Socrates was found guilty and he was sentenced to death.
