What if everything you’ve ever seen, touched, or believed was just a shadow on a wall? Fall asleep to the complete philosophy of Plato.

What if the real world, the world of permanent truth, was something you could only reach by turning away from everything familiar? For Plato, these were the most urgent questions a human being could face. Twenty-four centuries ago, in a city that had just executed his teacher for asking too many questions, Plato built a philosophical system so complete that Alfred North Whitehead once called all of Western philosophy a series of footnotes to it.

This episode traces Plato’s thought from its origins in the death of Socrates through the Theory of Forms, the Allegory of the Cave, the vision of the philosopher king in The Republic, the epistemology of recollection, Diotima’s ladder of love in the Symposium, the arguments for the immortality of the soul in the Phaedo, and the ethical framework of the examined life. Three hours. No music. A calm voice and one of the most foundational minds in human history.

Please listen only in safe, restful contexts.
