This chapter focuses on the role that allusion plays in establishing a shared language of intimacy. It describes how Wollstonecraft and Godwin, in their letters to one another, trade literary allusions as a way of flirting. That practice cast doubt on the transparency of speech, however, since the difficulty of openly expressing feeling, versus the relative ease of slipping into a literary cliché, led to the sense of distrust that also features throughout their letters. The tension between transparency and trust is further explored in the pair’s novels. Wollstonecraft’s The Wrongs of Woman; or, Maria presents a heroine who falls in love with a man based on the books he reads, in a manner which suggests either quixotic delusion or a defiant trust in the imagination. Godwin’s novels depict scenes of shared reading which rethink his earlier philosophical discussions of personal affection versus independence, and openness versus secrecy or reserve.
