That resolution depends upon this tone of the spirits, appears likewise from the effects of strong liquors, the fiery particles whereof crowding into the brain, strengthen the spirits; their operation imitates that of anger, which I said before was an ebullition of the spirits. It is for this reason, that most people when they are in drink, are sooner touched and more prone to anger, than at other times, and some raving mad without any provocation at all. It is likewise observed, that brandy makes men more quarrelsome at the same pitch of drunkenness than wine; because the spirits of distilled waters have abundance of fiery particles mixed with them, which the other has not. The contexture of spirits is so weak in some, that though they have pride enough, no art can ever make them fight, or overcome their fears; but this is a defect in the principle of the fluids, as other deformities are faults of the solids. These pusillanimous people, are never thoroughly provoked to anger, where there is any danger, and drinking makes them bolder, but seldom so resolute as to attack any, unless they be women or children, or such who they know dare not resist. This constitution is often influenced by health and sickness, and impaired by great losses of blood; sometimes it is corrected by diet; and it is this which the Duke de la Rochefoucauld means, when he says: vanity, shame, and above all constitution, make up very often the courage of men, and virtue of women. There is nothing that more improves the useful martial courage I treat of, and at the same time shows it to be artificial, than practice; for when men are disciplined, come to be acquainted with all the tools of death, and engines of destruction, when the shouts, the outcries, the fire and smoke, the grones of wounded, and ghostly looks of dying men, with all the various scenes of mangled carcases and bloody limbs tore off, begin to be familiar to them, their fear abate apace; not that they are now less afraid to die than before, but being used so often to see the same dangers, they apprehend the reality of them less than they did: as they are deservedly valued for every siege they are at, and every battle they are in, it is impossible but the several actions they share in, must continually become as many solid steps by which their pride mounts up; and thus their fear of shame, as I said before, will always be proportioned to their pride, increasing as the apprehension of the danger decreases, it is no wonder that most of them learn to discover little or no fear: and some great generals are able to preserve a presence of mind, and counterfeit a calm serenity within the midst of all the noise, horror, and confusion, that attend a battle.
