 and training them to be responsive to moral facts themselves. It is not clear whether there is any analogue to the unambiguous and independent negative feedback that a nurse receives after giving the wrong treatment in the case of making a mistaken moral judgment. Railton suggests that empathy might play such a role, noting that having a capacity to empathize and activating it in situ “appear […] to be important predictors of moral sensitivity and behavior” (2014: 844), for example by inhibiting violence. But while empathy can certainly give feedback about the (anticipated) responses of others, it is one thing to learn that others as a matter of fact, say, suffer because of or disapprove of what I did, and quite another to learn that such disapproval is merited. To attune affective responses to moral facts, it seems that it is the latter kind of feedback we would need.
