(94.) We need not wait twenty years to see a general alter his opinion on the most serious things as well as on those which appear most certain and true. I shall not venture to maintain that fire in its own nature, and independent of our sensations, is void of heat,[653] that is to say, nothing like what we feel in ourselves on approaching it, lest some time or other it may become as hot as ever it was thought; nor shall I advance that one straight line falling on another makes two right angles, or two angles equal to two right angles, for fear something more or less be discovered, and my proposition be laughed at; nor, to mention something else, shall I say, with the whole of France, that Vauban is infallible, and that this is an undoubted fact,[654] for who will guarantee me but that in a short time it may be hinted that even in sieges, in which lies his peculiar pre-eminence, and of which he is considered the best judge, he does not make some blunders, and is as liable to mistakes as Antiphilus is?[655] (95.) If you believe people who are exasperated against one another, and swayed by passion, a scholar is a mere sciolist,[656] a magistrate a boor or a pettifogger,[657] a financier an extortioner, and a nobleman an upstart; but it is strange these scurrilous names, invented by anger and hatred, should become so familiar to us, and that contempt, though cold and inert, should dare to employ them. (96.) You agitate yourself, and give yourself a good deal of trouble, especially when the enemy begins to fly, and the victory is no longer doubtful, or when a town has capitulated; in a fight or during a siege you like to be seen everywhere in order to be nowhere; to forestall the orders of the general for fear of obeying them, and to seek opportunities rather than to wait for them or receive them. Is your courage a mere pretence? (97.) Order your soldiers to keep some post where they may be killed, and where nevertheless they are not killed, and they prove they love both honour and life. (98.) Can we imagine that men who are so fond of life should love anything better, and that glory, which they prefer to life, is often no more than an opinion of themselves, entertained by a thousand people whom either they do not know or do not esteem?[658]
