Abstract

Decision-making depends on bringing evidence together with values: decision theory for example employs probabilities and utilities; health economic decisions employ measures such as quality of life. The hypothesis guiding this chapter is that bringing evidence together with values in clinical decision-making requires an exercise of phronesis. Our aim however is not to justify our guiding hypothesis. It is rather to outline an account of phronesis that is in principle fit for the purposes of clinical decision-making if our guiding hypothesis is correct. The chapter has three sections. Section 1 describes the growing gap between evidence and values in clinical decision-making: the missing link, we suggest, required to bridge this gap, is an appropriate account of phronesis. Section 2 provides an initial characterisation of the required account of phronesis via Michael Polanyi’s twin stipulation on the nature of tacit knowledge. Section 3 then fills out the required account using John McDowell’s characterisation of phronesis as a situation specific but at the same time conceptually structured form of practical discernment. A McDowellian account of phronesis, we argue, in satisfying Polanyi’s twin stipulation, provides an in-principle bridge between evidence and values. We conclude with a note on some of the further requirements if the gap is to be bridged not only in principle but in practice too.
