While some trust theorists have adverted to the vulnerabilities involved in trust, especially vulnerability to betrayal, the literature on trust has not engaged with recent work on the ethics of vulnerability. This paper initiates a dialogue between these literatures, and in doing so begins to explore the complex interrelations between vulnerability and trust. More specifically, it aims to show how trust can both mitigate and compound vulnerability. Through a discussion of two examples drawn from literary sources, the paper also investigates (...) the effects of pathogenic vulnerability on the psychic economies of trust and distrust. (shrink)
