What’s the Point of Understanding?
This final chapter extends the function-first approach to human understanding. It is argued that the concept of understanding serves the practical function of identifying good explainers, which is an important dimension of epistemic evaluation. This hypothesis throws light on a variety of issues, including the role of explanation in understanding, the relationship between understanding and knowledge, epistemic luck, and the value of understanding. This chapter also argues that understanding and knowledge play different social roles: roughly, knowledge is closely tied to answering our need for true beliefs, whereas understanding answers our need for good explanations. Everyday inquiry is typically aimed at true beliefs, which is why knowledge matters, but sometimes we need more than just true beliefs to get by in the world, which is why understanding is valuable.
