 Its re-emergence had an invigorating effect on the other two approaches, many of whose proponents then began to address these topics in the terms of their favoured theory. (One consequence of this has been that 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.) Interest in Kant’s virtue theory has redirected philosophers’ attention to Kant’s long neglected Doctrine of Virtue, and utilitarians have developed consequentialist virtue theories (Driver 2001; Hurka 2001). It has also generated virtue ethical readings of philosophers other than Plato and Aristotle, such as Martineau, Hume and Nietzsche, and thereby different forms of virtue ethics have developed (Slote 2001; Swanton 2003, 2011a).
