“Governments throughout history have been run by tyrants.”

The Canton, Ohio Speech, Anti-War Speech (1918)
Context: Wars throughout history have been waged for conquest and plunder. In the Middle Ages when the feudal lords who inhabited the castles whose towers may still be seen along the Rhine concluded to enlarge their domains, to increase their power, their prestige and their wealth they declared war upon one another. But they themselves did not go to war any more than the modern feudal lords, the barons of Wall Street go to war. The feudal barons of the Middle Ages, the economic predecessors of the capitalists of our day, declared all wars. And their miserable serfs fought all the battles. The poor, ignorant serfs had been taught to revere their masters; to believe that when their masters declared war upon one another, it was their patriotic duty to fall upon one another and to cut one another's throats for the profit and glory of the lords and barons who held them in contempt. And that is war in a nutshell. The master class has always declared the wars; the subject class has always fought the battles. The master class has had all to gain and nothing to lose, while the subject class has had nothing to gain and all to lose — especially their lives.
They have always taught and trained you to believe it to be your patriotic duty to go to war and to have yourselves slaughtered at their command. But in all the history of the world you, the people, have never had a voice in declaring war, and strange as it certainly appears, no war by any nation in any age has ever been declared by the people.
And here let me emphasize the fact — and it cannot be repeated too often — that the working class who fight all the battles, the working class who make the supreme sacrifices, the working class who freely shed their blood and furnish the corpses, have never yet had a voice in either declaring war or making peace. It is the ruling class that invariably does both. They alone declare war and they alone make peace.
Yours not to reason why;
Yours but to do and die.
That is their motto and we object on the part of the awakening workers of this nation.
If war is right let it be declared by the people. You who have your lives to lose, you certainly above all others have the right to decide the momentous issue of war or peace.

Context: Men suffer all their life long, under the foolish superstition that they can be cheated. But it is as impossible for a man to be cheated by any one but himself, as for a thing to be and not to be at the same time. There is a third silent party to all our bargains. The nature and soul of things takes on itself the guaranty of the fulfilment of every contract, so that honest service cannot come to loss. If you serve an ungrateful master, serve him the more. Put God in your debt. Every stroke shall be repaid. The longer the payment is withholden, the better for you; for compound interest on compound interest is the rate and usage of this exchequer.
The history of persecution is a history of endeavours to cheat nature, to make water run up hill, to twist a rope of sand. It makes no difference whether the actors be many or one, a tyrant or a mob. A mob is a society of bodies voluntarily bereaving themselves of reason, and traversing its work. The mob is man voluntarily descending to the nature of the beast. Its fit hour of activity is night. Its actions are insane like its whole constitution. It persecutes a principle; it would whip a right; it would tar and feather justice, by inflicting fire and outrage upon the houses and persons of those who have these. It resembles the prank of boys, who run with fire-engines to put out the ruddy aurora streaming to the stars. The inviolate spirit turns their spite against the wrongdoers. The martyr cannot be dishonored. Every lash inflicted is a tongue of fame; every prison, a more illustrious abode; every burned book or house enlightens the world; every suppressed or expunged word reverberates through the earth from side to side. Hours of sanity and consideration are always arriving to communities, as to individuals, when the truth is seen, and the martyrs are justified.
Thus do all things preach the indifferency of circumstances. The man is all. Every thing has two sides, a good and an evil. Every advantage has its tax. I learn to be content. But the doctrine of compensation is not the doctrine of indifferency. The thoughtless say, on hearing these representations, — What boots it to do well? there is one event to good and evil; if I gain any good, I must pay for it; if I lose any good, I gain some other; all actions are indifferent.
There is a deeper fact in the soul than compensation, to wit, its own nature. The soul is not a compensation, but a life. The soul is. Under all this running sea of circumstance, whose waters ebb and flow with perfect balance, lies the aboriginal abyss of real Being. Essence, or God, is not a relation, or a part, but the whole. Being is the vast affirmative, excluding negation, self-balanced, and swallowing up all relations, parts, and times within itself. Nature, truth, virtue, are the influx from thence. Vice is the absence or departure of the same.
