Charlotte Perkins Gilman’s utopian fiction dramatizes her reform agenda, which turned on redressing an “unnatural” division back in human history that resulted in the excessively feminine women and humanized men who defined the norm in her own day. Her 1915 novel Herland challenges by flipping traditional gender hierarchies and roles even as it retains while naturalizing other forms of privileged status. Throughout her career, Gilman grounded her politics in the domain of biological existence, initially endorsing the view that natural laws and processes left unimpeded would inevitably work to facilitate the progressively meliorative course of evolution. But the more she became convinced that humans had deviated from this course, the more ardently she advocated for an interventionist, biopolitical approach. By the time she wrote Herland, she was diagnosing a nation’s “health and vitality” based on the extent of degeneracy and impurity she detected in the social body under examination and prescribing drastic cures as needed. Herland thus reveals the author’s conservative tendencies; these increased as she aged and soured on the prospect of sweeping social reform, but they had been there all along, even in her seemingly radical theories of gender.
