This lecture discusses key ideas from the ancient philosopher Plato's work, The Republic, in particular book 10. Specifically it examines his discussion of.the knowledge possessed by three groups of people, when it comes to a product of art or craft - the users of the product, the makers of the product, and the imitative artists who depict the product.
