The goal of this chapter is to contribute to ignorance studies by taking advantage of the pragmatist epistemology of Peirce and Dewey, which, in my view, would be an “unfinished” business without facing sundry problems raised by ignorance studies. Five typical pragmatist claims provide the framework for this chapter. They can be endorsed by other philosophies, but their conjunction is typical of pragmatism: (1) the first is Peirce’s pragmatist maxim for clarifying our ideas, where the reference to “practical bearings”, to (...) situations, conducts and contexts, is pivotal; (2) the second is pragmatism’s focus on inquiry as a norm-governed practice, rather than on mere knowledge; (3) the third idea is their “externalism”, the conviction that mind, reason and knowledge are not properties of atomic individuals but are distributed over community of inquirers or “publics” and their environment; (4) the fourth idea is that philosophy has condemned itself to skepticism when it was looking for absolute theoretical certainties; and (5) the last claim is their rejection of the fact-value dichotomy. My own general claim is that pragmatism has under-appreciated relevance for understanding the epistemology of ignorance and its social implications, and each section explores one possible dimension – semantic, epistemic, externalist, doxastic and normative – for this contribution.
