A physician may be virtuous (kind, just, and honest) and still not know which actions are known as morally permissible. There are more ways to define "morally permissible." One is to break the words apart, to define "morally" and then "permissible." However, there is a more holistic way. In Ethics in the First Person, Deni Elliott defines permissibility thusly. Permitted [means] behavior that is within the bounds of the moral system.
