Plato the Athenian was the philosopher who founded the Academy and whose brilliant writings are the foundation texts of the entire western philosophical tradition. A student of Socrates, his dialogues use the Socratic method of question-and-answer to probe some of the most important questions humans have ever asked about our situation. What is true knowledge? How do we distinguish it from falsehood or mere opinion? Is the human soul immortal, and if so, what happens after death? How can we best organise a community and who should govern it? Should the arts be censored in the name of community wellbeing? What is the nature of true goodness, and how can a philosopher pursue the goal of achieving it? This talk focuses on Plato’s masterpiece, the Republic, but also considers the importance of the dialogues which are set during the very last days of Socrates.
