Men are merely on a lower or higher stage of an eminence, whose summit is God's throne infinitely above all; and there is just as much reason for the wisest as for the simplest man being discontent with his position, as respects the real quantity of knowledge he possesses.
John RuskinThe art of nations is to be accumulative, just as science and history are; the work of living men not superseding, but building itself upon the work of the past.
John Ruskin
