Moral conversion and Hume on freedom

According to Hume, for one to be responsible for an action, the action must flow from one’s character. But the actions that we praise people for the most include cases where someone breaks free from a corrupt character and changes for the good. These cases are not merely cases of slight responsibility, but are central cases of responsibility.

A Humean can, of course, say that there was some hidden determining cause in the convert’s character that triggered the action—perhaps some inconsistency in the corruption. But given determinism, why should we think that this hidden determining cause was indeed in the agent’s character, rather than being some cause outside of the character—some glitch in the brain, say? That the hidden determining cause was in the character is an empirical thesis for which we have very little evidence. So on the Humean view, we ought to be quite skeptical that the person who radically changes from bad to good is praiseworthy. We definitely should not take such cases to be among paradigm cases of praiseworthiness.
