Annette Baier delivers an appeal for our fundamental moral notions to be governed not by rules and codes but by trust: a moral prejudice. Topics covered range from violence and cruelty to love and justice, and are linked by a preoccupation with vulnerability and inequality of vulnerability, with trust and distrust of equals and with cooperation and isolation. Throughout, she is concerned with the theme of women's roles. In this exploration of the implications of trusting to trust rather than proscription, Baier interweaves anecdote and autobiography with readings of Hume and Kant.
