Well, it's good to see my old guys winning praise, but here's Tom Hodgkinson in the Independent... He ends his article:
Plato, Aristotle, Epicurus and the rest can be read with great ease by anybody, and they are just as relevant today as they were 2,300 years ago.
Lets leave the relevance bit for now and think about the first clause. You can read them, I suppose, with ease even if not with 'great ease'. There are good translations. But try Aristotle's Metaphysics. If you liked his Ethics, you'll love that. Or the second part of Plato's Parmenides... I'd like to think there's more to them than what an easy read can give you. Otherwise, I'm out of a job.
