Justice is the product of nature and labour - Pierre-Joseph Proudhon

The nineteenth century is in my eyes a creative age in which new principles are produced but in which nothing written will endure.

Antinomy, that is, the existence of two laws or tendencies which are opposed to each other, is possible, not only with two different things, but with one and the same thing. Considered in their thesis, that is, in the law or tendency which created them, all the economical categories are rational, — competition, monopoly, the balance of trade, and property, as well as the division of labor, machinery, taxation, and credit. But, like communism and population, all these categories are antinomical; all are opposed, not only to each other, but to themselves. All is opposition, and disorder is born of this system of opposition. Hence, the sub-title of the work, — “Philosophy of Misery.” No category can be suppressed; the opposition, antinomy, or contre-tendance, which exists in each of them, cannot be suppressed.

If I were asked to answer the following question: What is slavery? and I should answer in one word, It is murder, my meaning would be understood at once. No extended argument would be required to show that the power to take from a man his thought, his will, his personality, is a power of life and death; and that to enslave a man is to kill him. Why, then, to this other question: What is property! may I not likewise answer, It is robbery, without the certainty of being misunderstood; the second proposition being no other than a transformation of the first? I undertake to discuss the vital principle of our government and our institutions, property: I am in my right. I may be mistaken in the conclusion which shall result from my investigations: I am in my right. I think best to place the last thought of my book first: still am I in my right.
