The end of the old civilization has come; the face of the earth will be renewed under a new son. Let the present generation perish, let the old preva… - Pierre-Joseph Proudhon

Justice is the central star which governs societies, the pole around which the political world revolves, the principle and the regulator of all transactions. Nothing takes place between men save in the name of right; nothing without the invocation of justice. Justice is not the work of the law: on the contrary, the law is only a declaration and application of justice in all circumstances where men are liable to come in contact. If, then, the idea that we form of justice and right were ill-defined, if it were imperfect or even false, it is clear that all our legislative applications would be wrong, our institutions vicious, our politics erroneous: consequently there would be disorder and social chaos.
This hypothesis of the perversion of justice in our minds, and, as a necessary result, in our acts, becomes a demonstrated fact when it is shown that the opinions of men have not borne a constant relation to the notion of justice and its applications; that at different periods they have undergone modifications: in a word, that there has been progress in ideas. Now, that is what history proves by the most overwhelming testimony.

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?

The elements of justice are identical with those of algebra.
