I'm pleased to be able to share a draft translation containing the Introduction ("On Happiness"), Books I-V and the Epilogue from Pierre Leroux's "Humanity" (1840). This was an influential work in the 19th century and excerpts appeared in English in “The Present” and “The Spirit of the Age” alongside the anarchistic works of the era.
