Virtue-based ethics prioritizes _phronesis_ (practical wisdom) because, as rules have become less action-guiding, good judgment (_phronesis_) becomes more necessary as a guiding meta-virtue. The view of _phronesis_ that MacIntyre proposed in _After Virtue_ (hereafter, AV _phronesis_) has been applied in medical ethics despite his substantial deviations from his source (Aristotle) in _After Virtue_. In this paper, we clarify the differences between the neo-Aristotelian and AV _phronesis_ views and argue for a neo-Aristotelian _phronesis_ with four functions (constitutive, adjudicative, emotion regulative, and (...) blueprint). In referring to neo-Aristotelians, we refer to the recent scholars that who hark back strongly to Aristotle and have amended some of Aristotle’s less palatable views by adding insights from current empirical science to the domains that he left vague. Then we discuss how AV _phronesis_ and neo-Aristotelian _phronesis_ differ, focusing on the distinction between technical (i.e., alterable means toward patient health such as medication choices) and _phronetic_ (i.e., actions that are inseparable from patient health) actions in medicine. This distinction is understated in AV _phronesis_, but central to neo-Aristotelian _phronesis_. Accordingly, the neo-Aristotelian approach makes an important and unique contribution to physician ethical development. (shrink)
