This essay deals with some issues regarding ignorance that is morally
culpable. It is not always the case, however, that ignorance is surely culpable.
In some cases, it not at all clear whether certain ignorance should be criticized.
This essay takes issues with these kinds of cases. The purpose of this essay is
to show that relying upon epistemic virtues can be a way to decide whether
certain ignorance is morally culpable. To achieve this aim, I start with the
discussion of the case where an agent performs bad actions knowing that the
actions are bad and of the case where an agent performs bad actions because
of ignorance. Through this discussion, I make clear what questions should be
answered. The next issue that I deal with is whether utilitarianism can be an
appropriate theory which reflects our intuitions regarding the cases where an
agent performs wicked actions without knowing that the actions are really
wicked. I argue that utilitarianism cannot be a way to deal with the cases
reflecting our intuitions about the case. Next, I discuss what can be the cause
of the ignorance that is morally culpable. This discussion shows at least
indirectly that some epistemic virtues can be helpful for us to answer the
question of whether certain ignorance is morally culpable. Lastly, I argue that
we can decide whether certain ignorance is morally culpable by virtue of seeing
whether an agent who has ignorance possesses some epistemic virtues.
