In 1908 he published the book "Qu'est-ce qu'un anarchiste". In 1911 he married Denise Rougeault who helped him financially and with this he was able to concentrate on his activism. From 1922 on he published the magazine "L'EnDehors" which lasted around 17 years. At the same time he wrote "Poésies composées en prison", "l'Initiation individualiste anarchiste" (1923) and "La révolution sexuelle et la camaraderie amoureuse" (1934). In 1931 he published "Ways of communal life without state and authority. Economic and sexual experiences through history" in which he presented intentional communities anarchist and non-anarchist from different times. In it he argued that these experiments were ways of resistance and propaganda by the deed of the possibility of living differently according to affinity groups will. In this way he revitalized utopian socialist thought and practice of thinkers such as Robert Owen and especially Charles Fourier with whom he could also connect with his viewpoints on free love and freedom of personal exploration.
