For his third memoir on property, which took the shape of a letter to the Fourierist, M. Considérant, he was tried at Besançon, but was acquitted. In 1846 he published his greatest work, the _Système des contradictions économiques, ou philosophie de la misère_. For some time Proudhon carried on a small printing establishment at Besançon, but without success; and afterwards held a post as a kind of manager with a commercial firm at Lyons. In 1847 he left this employment, and finally settled in Paris, where he was now becoming celebrated as a leader of innovation. He regretted the sudden outbreak of the revolution of February, because it found the social reformers unprepared; but he threw himself with ardour into the conflict of opinion, and soon gained a national notoriety. He was the moving spirit of the _Représentant du Peuple_ and other journals, in which the most advanced theories were advocated in the strongest language; and as member of Assembly for the Seine department he brought forward his celebrated proposal for exacting an impost of one-third on interest and rent, which of course was rejected. His attempt to found a bank which should operate by granting gratuitous credit, was also a complete failure; of the five million francs which he required, only seventeen thousand were offered. The violence of his utterances led to an imprisonment at Paris for three years, during which he married a young working woman. As Proudhon aimed at economic rather than political innovation, he had no special quarrel with the Second Empire, and he lived in comparative quiet under it till the publication of his work, _De la justice dans la révolution et dans l’église_ (1858), in which he attacked the Church and other existing institutions with unusual fury. This time he fled to Brussels to escape imprisonment. On his return to France his health broke down, though he continued to write. He died at Passy in 1865. Personally, Proudhon was one of the most remarkable figures of modern France. His life was marked by the severest simplicity and even puritanism; he was affectionate in his domestic relations, a most loyal friend, and strictly upright in conduct. He was strongly opposed to the prevailing French socialism of his time because of its utopianism and immorality; and, though he uttered all manner of wild paradox and vehement invective against the dominant ideas and institutions, he was remarkably free from feelings of personal hate. In all that he said and did he was the son of the people, who had not been broken to the usual social and academic discipline; hence his roughness, his one-sidedness, and his exaggerations. But he is always vigorous, and often brilliant and original.
