Proudhon Notes
“Proudhon’s relevance to modern society is an example of the way in which a writer’s signif- icance can seem to change with changing historical circumstances. He began, in Qu’est-ce que la propriété? as an advocate of the peasant and the small handcraftsman, the workers as he had known them in Besançon and in the workshop quarters of Lyons and Paris. Later, as railways developed and the industrial revolution spread in France, somewhat later than in Britain, he adapted his ideas to allow for the association of workers on a larger scale. But he did so with misgivings, since his heart was in a society where work relationships were on a more intimate scale, and in consequence he gained the reputation, among Marxists and even among anarchist communists and revolutionary syndicalists, of being a pre-industrialist thinker, speaking for a past age of small proprietors.

But history has turned on its axis, and now, in a post-industrial age, we are beginning to look again at our economic and social relationships, and to realize that the mass structures of the recent past have themselves become obsolete. In such a situation Proudhon seems to be transformed from a retrograde into a progressive thinker. I am not admitting that he was ever out of place, for I think that in their day both the Marxists and the revolutionary syndicalists were wrong in accepting so uncritically the phenomenon of largescale and centralized industrial organization. But I think that today, now that we know all the social, economic, and ecological evils of industrial gigantism (and of political gigantism as well), Proudhon, even more than the other great anarchists, is our man, his voice speaking as clearly to the problems of our day as it did to the problems of his own time.” – George Woodcock, A Personal Preface to the Third Edition of Pierre-Joseph Proudhon: A Biography
