it is now necessary to distinguish “virtue ethics” (the third approach) from “virtue theory”, a term which includes accounts of virtue within the other approaches.

Whereas consequentialists will define virtues as traits that yield good consequences and deontologists will define them as traits possessed by those who reliably fulfil their duties, virtue ethicists will resist the attempt to define virtues in terms of some other concept that is taken to be more fundamental. Rather, virtues and vices will be foundational for virtue ethical theories and other normative notions will be grounded in them.
