accidie (also acedia), apathy, listlessness, or ennui. This condition is problematic for the internalist thesis that, necessarily, any belief that one morally ought to do something is conceptually sufficient for having motivation to do it. Ann has long believed that she ought, morally, to assist her ailing mother, and she has dutifully acted accordingly. Seemingly, she may continue to believe this, even though, owing to a recent personal tragedy, she now suffers from accidie and is wholly lacking in motivation to assist her mother.
