androgyny in the 1840s

A random connection, about which, or around which, there is perhaps already a book: Celestin Bouglé, in a 1910 article about Proudhon, mentions that it is the couple ‘androgyne’ which is the basic unit of justice for Proudhon (this is on page 371 of the September 15^th 1910 issue of Revue de Paris). I remember from reading Barthes’ book on Michelet that this historian, a contemporary of Proudhon’s, also speaks about the necessity of androgyny for true historical understanding. Certainly Fourier and Saint-Simon (or at least his followers) did some serious thinking about the nature and meaning of gender difference. I wonder how much this has been worked out? Certainly it's an argument for thinking harder about the roots of Third Republic-era republican gender ideology.
