This he cannot do, if he is Artaxerxes’s physicianSee Ctesias in Notes., trembling before him, or hoping to get a purple cloak, a golden chain, a horse of the Nisaean breed, in payment for his laudations. A fair historian, a Xenophon, a Thucydides, will not accept that position. He may nurse some private dislikes, but he will attach far more importance to the public good, and set the truth high above his hate; he may have his favourites, but he will not spare their errors. 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.

Any one who is intent only upon the immediate effect may reasonably be classed among the flatterers; and History has long ago realized that flattery is as little congenial to her as the arts of personal adornment to an athlete’s training. An anecdote of Alexander is to the point. ‘Ah, Onesicritus,’ said he, how I should like to come to life again for a little while, and see how your stuff strikes people by that time; at present they have good enough reason to praise and welcome it; that is their way of angling for a share of my favour.’ On the same principle some people actually accept Homer’s history of Achilles, full of exaggerations as it is; the one great guarantee which they recognize of his truth is the fact that his subject was not living; that leaves him no motive for lying.
