 Different answers to the question of when trust is warranted give rise to different philosophical puzzles. For example, in response, one could appeal to the nature of trust and trustworthiness and consider whether the conditions are ripe for them (e.g., for the proposed trustor to rely on the trustee’s competence). But one would first have to settle the difficult issue of what trust and trustworthiness are, and more specifically, how they differ from mere reliance and reliability, assuming there are these differences.
