Trust requires reliance on another's goodwill, not just predictability. [definitional]
Continuity of the relationship is not enough, of course, because the commitments matter. In a favorite philosopher's example, Immanuel Kant's neighbors may have relied on his punctuality in his morning walk to set their own schedules. To trust him, however, would require more: that they rely on his having their interests at heart in deciding when to take his walk. If they could not think he did, they could not be said to trust him in the strong sense of the encapsulated-interest account (Baier 1986, 234).
DEFINE: Clarifies the 'encapsulated-interest' account of trust, distinguishing it from mere reliance on regularity.
