We call Socrates the father of Western philosophy, but what exactly are his philosophical views? He is famous for his humility, but readers often find him arrogant and condescending. We parrot his claim that 'the unexamined life is not worth living,' yet take no steps to live examined ones. We know that he was tried, convicted and executed for 'corrupting the youth,' but freely assign Socratic dialogues to today's youths, to introduce them to philosophy. We've lost sight of what made him so dangerous. In 'Open Socrates', Agnes Callard recovers the radical energy at the centre of Socrates' thought and shows why it is still the way to a good life.
