Contemporary accounts of what it is for an agent to be justified in holding a given belief commonly carry substantive commitments concerning what cognitive processes can and should be like. In this paper, we argue that concern for the plausiblity of such psychological commitments leads to significant epistemological results. In particular, it leads to a multi-faceted epistemology in which elements of traditionally conflicting epistemologies are vindicated within a single epistemological account. We suggest thinking of the epistemologically relevant cognitive processes in terms of the metaphor of an iceberg--the accessible and articulable states that have been the exclusive focus of much epistemology must, for reasons that we explain, comprise only a proper subset of epistemologically relevant processing, even as only a part of an iceburg is exposed to view. When one focuses on the interaction of accessible states and articulable information, the structure of epistemic justification looks rather like what has been called structural contextualism (Timmons 1993, Henderson 1994b). It might also be called quasi-foundationalist. Yet, given the sort of creatures we are, in attending to our epistemological tasks we must rely on processing that is sensitive to information that we could not articulate, that is not accessible in the standard internalist sense. When one focuses on the full range of epistemologically important processes, the structure of what makes for justification may be rather more like that envisioned by some coherentists.
