What it is to Possess a Reason
This chapter defends the book’s official view of possession. It starts by arguing that meeting the epistemic condition is not sufficient for possession. There are cases where one meets the epistemic condition but fails to possess because one does not appreciate the normative relevance of the fact in question. The bulk of the chapter is dedicated to spelling out what it takes to adequately appreciate normative relevance. Arguments are given against subjective reason accounts and Humean accounts. It is argued that what it is to possess a reason is to be in a position to manifest knowledge about how to use the reason as the reason that it is. Finally, it is argued that meeting the epistemic condition is a background condition for being in a position to manifest the relevant know-how.
