Further to my recent post on Plato’s cave, here is a three-minute introduction to the entirety of Plato’s philosophy. It necessarily leaves a few things out, but the cave allegory gets a mention!
Again, this is just an appetiser. It’s no substitute to actually reading one of Plato’s dialogues — I recommend his Symposium, or The Republic for the adventurous. Plato is a “must-read” for anyone desiring a rounded cultural formation. And there’s no time like the summer for some cultural reading!
