“[War] is the nastiest thing human beings can do to each other … but the most exciting…”
Ernest Hemingway, On War, 161
“But under no circumstances can we inflict violence on people, torture or kill them because we think such acts could be of use to us or to others. We cannot and may not do such things, especially because we can never be sure of the results of our actions.”
Leo Tolstoy, Advice to a Draftee, April 7, 1899
“The wars we haven’t had saved many lives.”
“…it still appears to me that, while the seat of government is in Washington, the seat of conscience is in me. It cannot be voted out of office by one or a million others.”
Juanita Nelson, life-long civil rights activist, pacifist and tax-resister.
“When you see a war as I have seen it, you ask yourself: “How can we put up with such a thing? What frontier traced on a map, what national honor could possibly justify it? How can what is nothing more than banditry be dressed up as an ideal, and allowed to happen?
“They told the Germans: ‘Forward to a bright and joyous war! On to Paris! God is with us, for a greater Germany!’ And the good, peaceful Germans, who take everything seriously, set forth to conquer, transforming themselves into savage beasts.
“They told the French: ‘The nation is under attack. We will fight for Justice and Retribution. On to Berlin! And the pacifist French, the French who take nothing at all seriously, interrupted their little modest rentier reveries to go and fight.
“So it was with the Austrians, the Belgians, the English, the Russians, the Turks, and then the Italians. In a single week, twenty million men, busy with their lives and loves, with making money and planning a future, received the order to stop everything to go and kill other men. And those twenty million individuals obeyed the order because they had been convinced that this was their duty. ”
Gabriel Chevallier, Fear: A Novel of World War I, translated by Malcolm Imrie, (1930/2011)
“If in any country whatever a recruiting campaign were to be launched today for some utterly preposterous war, a war in Polynesia or in some corner of Africa, thousands and hundreds of thousands would rush to the colours without really knowing why, perhaps merely out of a desire to run away from themselves or from disagreeable circumstances. But as for any effective opposition to a war — I wouldn’t care to put it above zero. It always demands a far greater degree of courage for an individual to oppose an organized movement than to let himself be carried along with the stream — individual courage, that is, a variety of courage that is dying out in these times of progressive organization and mechanization. During the war [WW I] practically the only courage I came across was mass courage, the courage that comes of being one of a herd, and anyone who examines this phenomenon more closely will find it to be compounded of some very strange elements: a great deal of vanity, a great deal of recklessness and even boredom, but, above all, a great deal of fear — yes, fear of staying behind, fear of being sneered at, fear of independent action, and fear, above all, of taking a stand against the mass enthusiasm of one’s fellows.”
–Stefan Zweig, Beware of Pity New York Review Books Classics
“Of all the enemies to public liberty war is, perhaps, the most to be dreaded, because it comprises and develops the germ of every other. War is the parent of armies; from these proceed debts and taxes; and armies, and debts, and taxes are the known instruments for bringing the many under the domination of the few. In war, too, the discretionary power of the Executive is extended; its influence in dealing out offices, honors, and emoluments is multiplied; and all the means of seducing the minds, are added to those of subduing the force, of the people. The same malignant aspect in republicanism may be traced in the inequality of fortunes, and the opportunities of fraud, growing out of a state of war, and in the degeneracy of manners and of morals engendered by both. No nation could preserve its freedom in the midst of continual warfare,”
Preparations for the slaughter of mankind have always been made in the name of God or some supposed higher being which men have devised and created in their own imagination.
Jaroslav Hašek The Good Soldier Švejk, (1923) Book I, Chapter 11, Cecil Parrott translation
Congressman Abraham Lincoln criticizing President Polk who…”trusting to escape scrutiny, by fixing the public gaze upon the exceeding brightness of military glory–that attractive rainbow, that rises in showers of blood–that serpent’s eye, that charms to destroy, he plunged into it, and has swept, on and on, till, disappointed in his calculation of the ease with which Mexico might be subdued, he now finds himself, he knows not where.”
Lincoln’s Speech in House: The War with Mexico January 12, 1848
“In no part of the constitution is more wisdom to be found than in the clause which confides the question of war or peace to the legislature, and not to the executive department. Beside the objection to such a mixture of heterogeneous powers: the trust and the temptation would be too great for any one man: not such as nature may offer as the prodigy of many centuries, but such as may be expected in the ordinary successions of magistracy. War is in fact the true nurse of executive aggrandizement. In war a physical force is to be created, and it is the executive will which is to direct it. In war the public treasures are to be unlocked, and it is the executive hand which is to dispense them. In war the honors and emoluments of office are to be multiplied; and it is the executive patronage under which they are to be enjoyed. It is in war, finally, that laurels are to be gathered, and it is the executive brow they are to encircle. The strongest passions, and most dangerous weaknesses of the human breast; ambition, avarice, vanity, the honorable or venial love of fame, are all in conspiracy against the desire and duty of peace.”
The chaplain had mastered, in a moment of divine intuition, the handy technique of protective rationalization and he was exhilarated by his discovery. It was miraculous! It was almost no trick at all to turn vice into virtue, and slander into truth, impotence into abstinence, arrogance into humility, plunder into philanthropy, thievery into honor, blasphemy into wisdom, brutality into patriotism and sadism into justice. And anybody could do it!
“War was a world with no home, no roof, no comforts. A miserable journey, of endless drifting. War was a world without real men, without real women. Without feeling.”
“What remained was sorrow, the immense sorrow, the sorrow of having survived. The sorrow of war.”
Bao Ninh, The Sorrow of War,  translation by Frank Palmos 
“War is the final destination of hatred.”
Ernest Gordon, former POW, Dean of Chapel at Princeton and author of To End All War, a novel of life in Japanese prison labor camps in Burma, WW II.
“They are not soldiers, they are men. They are not adventurers, or warriors, or made for human slaughter, neither butchers nor cattle. They are laborers and artisans whom one recognizes in their uniforms,. They are civilians uprooted, and they are ready. They await the signal for death or murder; but you may see, looking at their faces, between the vertical gleams of their bayonets, that they are simply men.
Each one knows that he is going to take his head, his chest, his belly, his whole body forward, and all naked, up to the rifles pointed forward, to the shells, to the bombs piled and ready, and above all to the methodical and almost infallible machine guns….
Henri Barbusse, Under Fire [Le feu], translation by W. Fitzwater Wray
“..at that time  even one’s parents were ready with the word “coward”; no one had the vaguest idea what we were in for. The wisest were just the poor and simple people. They knew the war to be a misfortune, whereas those who were better off, and should have been able to see more clearly what the consequences would be, were beside themselves with joy.
