It would be useful to have systematic analyses of trust that is grounded in each of the bases of trustworthiness discussed here: internal, external, and mixed motivations. In this book, I focus primarily on encapsulated interest as the ground for trustworthiness, although I also discuss categories that are closely related to encapsulated interest. I think it will be harder to give systematic accounts of trust in all its workings for trustworthiness that is grounded in moral commitments, norms, and bald dispositions. The knowledge problems of assessing such commitments in general seem likely to be harder than those for assessing interests.

DEFINE: Distinguishes encapsulated-interest trustworthiness from grounds of moral commitments, norms, and bald dispositions, with the latter posing harder knowledge problems. QUESTION: Why are interests inherently easier to assess than moral commitments? Is this an empirical claim or a conceptual one?
