 Trust is an attitude we have towards people whom we hope will be trustworthy, where trustworthiness is a property not an attitude. Trust and trustworthiness are therefore distinct although, ideally, those whom we trust will be trustworthy, and those who are trustworthy will be trusted. For trust to be plausible in a relationship, the parties to the relationship must have attitudes toward one another that permit trust. Moreover, for trust to be well-grounded, both parties must be trustworthy. (Note that here and throughout, unless specified otherwise, “trustworthiness” is understood in a thin sense according to which X is trustworthy for me just in case I can trust X.)
