 Reflection on perfect goodness is most commonly carried out as part of the project of philosophical theology. One prominent methodological strand of philosophical theology is perfect being theology, in which the nature of God is made more explicit by identifying God as an absolutely perfect being and working out what features an absolutely perfect being must exhibit (Morris 1989c; Rogers 2000; Nagasawa 2008). As it is a commonplace that one of the perfections that would have to be exhibited by any being that would qualify as absolutely perfect is perfect goodness, it is obvious why philosophical theologians employing perfect being theology would be motivated to reflect in some detail on the character of perfect goodness and to consider various challenges to the very idea.
