If you can't read Chaucer without a translation, or puzzle your way through a page of Cicero's Latin, you aren't educated. If you don't have a few dozen tags of Homer within easy reach in your mind, or a few hundred lines of Shakespeare, you lack part of what high schools and colleges were created to teach. If you can't name the books of the Bible, or the circles of Dante's Hell, there are pieces missing from what we once assumed learned people should know.
For that matter, if you can't say how the Romans lost at Cannae, or how the Ten Thousand marched from Persia, or how Troy was defeated, then what was all your schooling for?
