We are currently in the midst of a revival of interest in the virtues. A nu
mber of contemporary moral philosophers have defended a virtue-based approa
ch to ethics. But does this renewal of interest in the virtues have much to
contribute to medical ethics and medical practice ? This paper critically
discusses this question. It considers and rejects a number of important arg
uments that purport to establish the significance of the virtues for medica
l practice. Against these arguments, the paper seeks to show that while the
virtues have a genuine role to play in medical ethics, it is a limited rol
e, one that is subordinate to the role that other moral concepts such as ru
les and principles play.
