“At many stages in the advance of humanity, this conflict between the men who possess more than they have earned and the men who have earned more than they possess is the central condition of progress. In our day it appears as the struggle of freemen to gain and hold the right of self-government as against the special interests, who twist the methods of free government into machinery for defeating the popular will. At every stage, and under all circumstances, the essence of the struggle is to equalize opportunity, destroy privilege, and give to the life and citizenship of every individual the highest possible value both to himself and to the commonwealth.”

The Education of Henry Adams (1907)
Context: The work of domestic progress is done by masses of mechanical power — steam, electric, furnace, or other — which have to be controlled by a score or two of individuals who have shown capacity to manage it. The work of internal government has become the task of controlling these men, who are socially as remote as heathen gods, alone worth knowing, but never known, and who could tell nothing of political value if one skinned them alive. Most of them have nothing to tell, but are forces as dumb as their dynamos, absorbed in the development or economy of power. They are trustees for the public, and whenever society assumes the property, it must confer on them that title; but the power will remain as before, whoever manages it, and will then control society without appeal, as it controls its stokers and pit-men. Modern politics is, at bottom, a struggle not of men but of forces. The men become every year more and more creatures of force, massed about central power-houses. The conflict is no longer between the men, but between the motors that drive the men, and the men tend to succumb to their own motive forces.

Part I, Essay 4: Of The First Principles of Government
Essays, Moral, Political, and Literary (1741-2; 1748)
Context: Nothing appears more surprising to those, who consider human affairs with a philosophical eye, than the easiness with which the many are governed by the few; and the implicit submission, with which men resign their own sentiments and passions to those of their rulers. When we enquire by what means this wonder is effected, we shall find, that, as Force is always on the side of the governed, the governors have nothing to support them but opinion. It is therefore, on opinion only that government is founded; and this maxim extends to the most despotic and most military governments, as well as to the most free and most popular.

1910s, The New Nationalism (1910)
Context: In every wise struggle for human betterment one of the main objects, and often the only object, has been to achieve in large measure equality of opportunity. In the struggle for this great end, nations rise from barbarism to civilization, and through it people press forward from one stage of enlightenment to the next. One of the chief factors in progress is the destruction of special privilege. The essence of any struggle for healthy liberty has always been, and must always be, to take from some one man or class of men the right to enjoy power, or wealth, or position, or immunity, which has not been earned by service to his or their fellows. That is what you fought for in the Civil War, and that is what we strive for now.
