Abstract
This essay draws on Ludwig Wittgenstein’s work to argue for a practice-oriented concept of expertise. We propose that conceptualizing types of expertise as having a family resemblance, relative to the problems such expertise addresses, escapes certain limitations of defining expertise as primarily epistemic. Recognizing the pragmatic purchase on actual problems a Wittgensteinian approach provides to discussions of expertise, we seek to understand the nature of expertise in situations where the people who need to make a difficult decision do not possess or have access to the epistemic status that traditionally confers expertise. These are situations where people need to answer difficult questions that, while they may be informed by expertise in the epistemic register, are ultimately decided by expertise that weighs certified knowledge against the intractable characteristics of a particular situation. We suggest that there is not—even deep down on a conceptual level—only one kind of expertise, but multiple kinds of expertise that resonate with diverse kinds of problems.
