text: I do, however, find some metaphors, not, indeed, daring ones, but the kind which have stood the test of use. I find similes also; of course, if anyone forbids us to use them, maintaining that poets alone have that privilege, he has not, apparently, read any of our ancient prose writers, who had not yet learned to affect a style that should win applause. For those writers, whose eloquence was simple and directed only towards proving their case, are full of comparisons; and I think that these are necessary, not for the same reason which makes them necessary for the poets, but in order that they may serve as props to our feebleness, to bring both speaker and listener face to face with the subject under discussion. For example, I am at this very moment reading Sextius; he is a keen man, and a philosopher who, though he writes in Greek, has the Roman standard of ethics. One of his similes appealed especially to me, that of an army marching in hollow square, in a place where the enemy might be expected to appear from any quarter, ready for battle. "This," said he, "is just what the wise man ought to do; he should have all his fighting qualities deployed on every side, so that wherever the attack threatens, there his supports may be ready to hand and may obey the captain's command without confusion." This is what we notice in armies which serve under great leaders; we see how all the troops simultaneously understand their general's orders, since they are so arranged that a signal given by one man passes down the ranks of cavalry and infantry at the same moment. This, he declares, is still more necessary for men like ourselves; for soldiers have often feared an enemy without reason, and the march which they thought most dangerous has in fact been most secure; but folly brings no repose, fear haunts it both in the van and in the rear of the column, and both flanks are in a panic. Folly is pursued, and confronted, by peril. It blenches at everything; it is unprepared; it is frightened even by auxiliary troops. But the wise man is fortified against all inroads; he is alert; he will not retreat before the attack of poverty, or of sorrow, or of disgrace, or of pain. He will walk undaunted both against them and among them.
