“The landed wealth of the Church alone sufficed to make it a power of the highest rank in the feudal system of the Middle Ages, in which all power finally rested on the possession of the land. Bishops and abbots became feudal dignitaries, sometimes almost sovereign princes in their own domains, and always with a potent voice in the government of their nations.”

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: A great change is going on all over the civilized world similar to that infeudation which, in Europe, during the rise of the feudal system, converted free proprietors into vassals, and brought all society into subordination to a hierarchy of wealth and privilege. Whether the new aristocracy is hereditary or not makes little difference. Chance alone may determine who will get the few prizes of a lottery. But it is not the less certain that the vast majority of all who take part in it must draw blanks. The forces of the new era have not yet had time to make status hereditary, but we may clearly see that when the industrial organization compels a thousand workmen to take service under one master, the proportion of masters to men will be but as one to a thousand, though the one may come from the ranks of the thousand. "Master"! We don't like the word. It is not American! But what is the use of objecting to the word when we have the thing? The man who gives me employment, which I must have or suffer, that man is my master, let me call him what I will.
