How came the people to err? How happens it that, when seeking liberty and equality, they fell back into privilege and slavery? Always through copying… - Pierre-Joseph Proudhon

Property is robbery! That is the war-cry of '93! That is the signal of revolutions! Reader, calm yourself: I am no agent of discord, no firebrand of sedition. I anticipate history by a few days; I disclose a truth whose development we may try in vain to arrest; I write the preamble of our future constitution. This proposition which seems to you blasphemous — property is robbery — would, if our prejudices allowed us to consider it, be recognized as the lightning-rod to shield us from the coming thunderbolt; but too many interests stand in the way! ... Alas! philosophy will not change the course of events: destiny will fulfill itself regardless of prophecy. Besides, must not justice be done and our education be finished?

1. Sovereignty of the human will; in short, despotism. 2. Inequality of wealth and rank. 3. Property — above JUSTICE, always invoked as the guardian angel of sovereigns, nobles, and proprietors; JUSTICE, the general, primitive, categorical law of all society.
We must ascertain whether the ideas of despotism, civil inequality and property, are in harmony with the primitive notion of justice, and necessarily follow from it, — assuming various forms according to the condition, position, and relation of persons; or whether they are not rather the illegitimate result of a confusion of different things, a fatal association of ideas. And since justice deals especially with the questions of government, the condition of persons, and the possession of things, we must ascertain under what conditions, judging by universal opinion and the progress of the human mind, government is just, the condition of citizens is just, and the possession of things is just; then, striking out every thing which fails to meet these conditions, the result will at once tell us what legitimate government is, what the legitimate condition of citizens is, and what the legitimate possession of things is; and finally, as the last result of the analysis, what justice is.

The proprietor, the robber, the hero, the sovereign — for all these titles are synonymous — imposes his will as law, and suffers neither contradiction nor control; that is, he pretends to be the legislative and the executive power at once ... [and so] property engenders despotism ... That is so clearly the essence of property that, to be convinced of it, one need but remember what it is, and observe what happens around him. Property is the right to use and abuse ... if goods are property, why should not the proprietors be kings, and despotic kings — kings in proportion to their facultes bonitaires? And if each proprietor is sovereign lord within the sphere of his property, absolute king throughout his own domain, how could a government of proprietors be any thing but chaos and confusion?
