"For history, I say again, has this and this only for its own: if a man will start upon it, he must sacrifice to no god but Truth; he must neglect all else; his sole rule and unerring guide is this – to think not of those who are listening to him now, but of the yet unborn who shall seek his converse"

-- Lucian of Samosata, How to Write History, 2nd c. CE
