War looks sweet only to those who have never tasted it. Erasmus turns this proverb, "Dulce bellum inexpertis," into a full-scale indictment of human folly, moral blindness, and theological hypocrisy. It is a sermon delivered by a man who has been forced to sit through too many parades of victory and too many pious speeches about "honor."
Nature, he says, gave horns to bulls, claws to lions, tusks to boars, and to man she gave nothing but soft skin and a voice fit for persuasion. A creature designed to embrace has somehow turned his arms into weapons. The human body, Erasmus observes, is an argument for peace written in flesh, though most men insist on reading it as a manual for mutual destruction.
From there he paints the scene of battle as a grotesque carnival: trumpets blare, blood fountains, brothers stab brothers, and the world’s most "reasonable" creature behaves worse than the beasts. Lions do not wage war on lions, he notes. Wolves, however nasty, rarely form committees to declare war on other wolves. Only man does this, and only man congratulates himself for it.
Having mocked the philosophers who dignify war with "natural law" and the theologians who excuse it with divine creeds, Erasmus shifts his fire to the princes. They are, he says, the least fit to wage war and the most eager to start it. They hire scholars to justify their murders and clerics to bless their banners. Lawyers and priests, instead of quenching the flames, act as cheerleaders at the bonfire. He accuses them of inflating petty quarrels into "holy" crusades so that kings may look virtuous while behaving like highwaymen.
Then he compares the calm garden of peace with the wasteland of war. In peace, the plow hums, the orchard blooms, the scholar studies, and the young marry. In war, the plowshare rusts, the orchard burns, the scholar starves, and the young rot in armor. Erasmus treats this not as poetry but as bookkeeping: peace yields profit, war yields deficit. His wit grows acid when he points out that even in victory, everyone loses.
He traces the origins of war to habit, greed, and pride. First men hunted beasts, then each other, and soon enough they found that killing could be turned into a profession. What began as self-defense became sport, then business, then theology. War, he suggests, was invented by fools and perfected by bureaucrats.
The heart of the work comes when he turns from satire to moral outrage. He calls it monstrous that Christians, whose founder forbade even anger, should spill each other's blood in Christ's name. He writes with incredulity that priests carry the cross into battle, transforming the symbol of mercy into an emblem of organized cruelty.
And yet he never entirely despairs. Erasmus imagines a world where princes rule with reason instead of vanity, where theologians bless peace instead of conquest, where man remembers that he was made to speak before he was made to strike. His closing plea for moderation and mercy, addressed to Pope Leo X, reads like the last hopeful sigh of humanism before the cannons of Europe answered it.
Against War begins with a proverb, rises to a thunderous argument, and ends with an exhausted prayer. It is one of the most intelligent tantrums ever written. Erasmus despises war on every possible level: physical, moral, theological, economic, and aesthetic. His loathing is absolute and somehow elegant.
War is not a tragic necessity but a collective lapse of reason. It degrades every institution that touches it. The philosopher becomes a flatterer, the priest becomes a propagandist, and the prince becomes a murderer in velvet. Peace, by contrast, is not passive or weak; it is the natural state of a creature made for language and learning.
It is an eloquent reminder that civilization's greatest invention may also be its favorite suicide note. The fact that his arguments remain relevant is not a compliment to Erasmus's foresight; it is an indictment of everyone who came after him.
