Discusses the treatment of female sexuality, reproduction, birth control, abortion and maternity in Dark's fiction. Focuses on the dilemma of the 'rational woman': a 'problematic created by modernity', the conflict between 'the authority of the natural ... and the searching eye of the modern rationalist epistemologies of science'. 'In attempting to provide access to the rationalism of science for her women characters, Dark's texts set up this contest between nature and science as an unresolved or even impossible dilemma haunted by the inevitable spectre of madness' (29).
