I do not suppose you will object that the man with insight has no need of system and instruction upon the things he is ignorant of; in that case he might have played the harp or flute untaught, and in fact have been omniscient. But, as things are at present, he cannot perform in these ways untaught, though with some assistance he will learn very easily, and soon be able to get along by himself. You now know what sort of a pupil I (like the trainer) insist upon, He must not be weak either at understanding or at making himself understood, but a man of penetration, a capable administrator—potentially, that is,—with a soldierly spirit (which does not however exclude the civil spirit), and some military experience; at the least he must have been in camp, seen troops drilled or manceuvred, know a little about weapons and military engines, the differences between line and column, cavalry and infantry tactics (with the reasons for them), frontal and flank attacks; in a word, none of your armchair strategists relying wholly on hearsay. But first and foremost, let him be a man of independent spirit, with nothing to fear or hope from anybody; else he will be a corrupt judge open to undue influences. If Philip’s eye is knocked out at Olynthus by Aster the Amphipolite archer, it is not his business to exclaim, but just to show him as he is; he is not to think whether Alexander will be annoyed by a circumstantial account of the cruel murder of Clitus at table. If a Cleon has the ear of the assembly, and a monopoly of the tribune, he will not shrink on that account from describing him as a pestilent madman; all Athens will not stop him from dwelling on the Sicilian disaster, the capture of Demosthenes, the death of Nicias, the thirst, the foul water, and the shooting down of the drinkers. He will consider very rightly that no man of sense will blame him for recounting the effects of misfortune or folly in their entirety; he is not the author, but only the reporter of them. If a fleet is destroyed, it is not he who sinks it; if there is a rout, he is not in pursuit—unless perhaps he ought to have prayed for better things, and omitted to do so. Of course, if silence or contradiction would have put matters right, Thucydides might with a stroke of the pen have knocked down the counterwall on Epipolae, sent Hermocrates’s trireme to the bottom, let daylight through the accursed Gylippus before he had done blocking the roads with wall and trench, and, finally, have cast the Syracusans into their own quarries and sent the Athenians cruising round Sicily and Italy with Alcibiades’s first high hopes still on board. Alas, not Fate itself may undo the work of Fate. The historian’s one task is to tell the thing as it happened. This he cannot do, if he is Artaxerxes’s physician See 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.
