Trust is almost entirely absent from moral philosophy proper

Evidence

As it happens, the literature on trust is richest in sociological accounts, such as Bernard Barber’s (1983) The Logic and Limits of Trust. Philosophers, economists, psychologists, and political theorists, especially those in the tradition of John Locke, have addressed trust and have given interesting insights; but there is surprisingly little in all of these disciplines. Discussions of trust are almost entirely missing from moral philosophy, where trust may be most often invoked in discussions of Kantian proscriptions on lying, as in Sissela Bok’s (1978) Lying: Moral Choice in Public and Private Life. — Russell Hardin, Trust and Trustworthiness, 47

• QUESTION: Why would moral philosophy neglect a concept so central to cooperative social life? Worth chasing the history of this lacuna.
• XREF: connects to: Enlightenment moral doctrines are mere propaganda lacking philosophical justification.
