In recent years, there has been increasing discontent with feminism’s understanding of its own history and, more specifically, the place of the feminist 1970s. Feminist scholars – most prominently, Elizabeth Freeman, Victoria Hesford, Kate Eichhorn and Kathi Weeks – have sought to move beyond the feelings of progress and nostalgia that the feminist 1970s often inspires. There is a need to mediate between the urge to leave the past behind and the desire to return to it, with feminists adopting positions that ricochet between progress and nostalgia. In this article, I argue that the feminist literary utopia offers a particularly productive means by which to represent this ambivalent, paradoxical temporal understanding. The classic feminist utopias of the 1970s have become the object of critical contention in more recent speculative texts, which destabilise both progress and nostalgia in their evocation of second-wave separatism. To elaborate this claim, I turn to Sarah Hall’s The Carhullan Army, which critically assesses the feminist 1970s via an account of a separatist feminist enclave in a near-future Britain. The community of women is a homage to the feminist 1970s, displaying both the potentialities of the movements of this time as well as their sometimes violent limitations. The dreams of the 1970s emerge in the text as an unsettling presence in the world, a force that can neither be left behind nor fully embraced.
