 Alternatively, in deciding whether trust is warranted, one could consider whether trust would be rationally justified or valuable. One would consider these things simultaneously when rational justification is understood in an end-directed way, making it dependent on trust’s instrumental value. With respect to rational justification alone, puzzles arise when trying to sort out whether reasons for trust must be internal to trustors or could be external to them. In other words, is trust’s epistemology internalist or externalist? Because good arguments exist on both sides, it’s not clear how trust is rationally justified. Neither is it entirely clear what sort of value trust can have, given the nature of it. For example, trust may or may not have intrinsic moral value depending on whether it signals respect for others.
