His advance in the direction of Communism was the turning-point in Owen's life. As long as he was simply a philanthropist, he was rewarded with nothing but wealth, applause, honor, and glory. He was the most popular man in Europe. Not only men of his own class, but statesmen and princes listened to him approvingly. But when he came out with his Communist theories, that was quite another thing. Three great obstacles seemed to him especially to block the path to social reform: private property, religion, the present form of marriage. He knew what confronted him if he attacked these--outlawry, excommunication from official society, the loss of his whole social position. But nothing of this prevented him from attacking them without fear of consequences, and what he had foreseen happened. Banished from official society, with a conspiracy of silence against him in the press, ruined by his unsuccessful Communist experiments in America, in which he sacrificed all his fortune, he turned directly to the working-class and continued working in their midst for thirty years. Every social movement, every real advance in England on behalf of the workers links itself on to the name of Robert Owen. He forced through in 1819, after five years' fighting, the first law limiting the hours of labor of women and children in factories. He was president of the first Congress at which all the Trade Unions of England united in a single great trade association. He introduced as transition measures to the complete communistic organization of society, on the one hand, cooperative societies for retail trade and production. These have since that time, at least, given practical proof that the merchant and the manufacturer are socially quite unnecessary. On the other hand, he introduced labor bazaars for the exchange of the products of labor through the medium of labor-notes, whose unit was a single hour of work; institutions necessarily doomed to failure, but completely anticipating Proudhon's bank of exchange of a much later period, and differing entirely from this in that it did not claim to be the panacea for all social ills, but only a first step towards a much more radical revolution of society.
