Trust requires time enough for repeated interactions on which to ground it.

Evidence

Aristotle (Eudemian Ethics 8.2.123b.12–16) notes that “there is no stable friendship [philia] without trust [pistis], and there is no trust without time.” We may suppose that the point of time in this claim is to have opportunity for enough interactions—including interactions into the future—on which to ground trust. — Russell Hardin, Trust and Trustworthiness, 906

Categorization

• XREF: This is the earliest articulation of the repeated-interaction grounding of trust that Hardin later builds into his encapsulated-interest account; connects to the Milgrom repeated-game cooperation logic. Also resonates with the reading purpose’s Luhmann familiarity-through-time baseline.
• QUESTION: Does Aristotle’s ‘trust requires time’ imply that trust is inherently backward-looking (empirical history) while Hardin’s account also needs forward-looking expectations? Worth pinning down how Hardin develops time into future interactions.
