A Kantian Account of Moral Trust

In this paper, I propose a Kantian framework for moral trust—trust in another person to only act with us in morally permissible ways. First, I derive an understanding of trustworthiness from Kant's second formulation of the categorical imperative. I argue that trustworthiness embodies a moral imperative, guiding us to act in ways that are reliable and recognizable as conducive to engaging in trusting relations. However, this alone is not enough, as it doesn't provide a means to assess whether someone is truly committed to the moral law and thus morally trustworthy. Therefore, in the second part, I explore a basis for assessing their moral conduct found in a local version of the Kingdom of Ends: given an ideal or archetype of a morally perfect interpersonal relationship, an archetype of the morally trustworthy agent allows us to comparatively assess the moral disposition of fellow agents.
