I might well have taken this discourse in an order like this: to show the vanity of all conditions of men, to show the vanity of ordinary lives, and then the vanity of philosophic lives, sceptics, stoics; but the order would not have been kept. I know a little what it is, and how few people understand it. No human science can keep it.did not keep it. Mathematics keep it, but they are useless on account of their depth.
