Proudhon's opposition to the state, organized religion and certain capitalist practices inspired subsequent anarchists and made him one of the leading social thinkers of his time. However, French anarchist Joseph Déjacque castigated Proudhon for his sexist economic and political views in a scathing letter written in 1857. He argued that "it is not the product of his or her labour that the worker has a right to, but to the satisfaction of his or her needs, whatever may be their nature."
