This article defends the centrality of practical wisdom in medical practice by building on a monistic view of moral virtue, termed the "Aretai model," according to which possession of practical wisdom is necessary and sufficient for virtuousness, grounding both moral growth and effective moral behavior. From this perspective, we argue that practical wisdom should be conceived as a cross-situational ethical expertise consisting of four skills:moral perception, moral deliberation, emotion regulation, and moral motivation. Conceiving of practical wisdom as both overall virtuousness and ethical expertise makes it possible to deal adequately with the uniqueness of concrete ethically relevant situations. We contend that this becomes particularly evident in the context of medical practice, both in terms of decision-making and action-taking, especially in the most challenging or contentious clinical cases. We conclude the article by suggesting the potential implications of the Aretai model for continuing education in medical and healthcare professions.
