At most, the greatest persons, are but great wens, and excrescences; men of wit and delightfull conversation, but as moales for ornament, except they be so incorporated into the body of the world, that they contribute something to the sustentation of the whole. [John Donne, letter to Sir Henry Goodere, Sept. 1608]
