The paper provides a systematic overview of recent debates in epistemology and philosophy of science on the nature of understanding. We explain why philosophers have turned their attention to understanding and discuss conditions for “explanatory” understanding of why something is the case and for “objectual” understanding of a whole subject matter. The most debated conditions for these types of understanding roughly resemble the three traditional conditions for knowledge: truth, justification and belief. We discuss prominent views about how to construe these (...) conditions for understanding, whether understanding indeed requires conditions of all three types and whether additional conditions are needed.

Understanding has received growing interest from epistemologists in recent years, but no consensus regarding its epistemic properties has yet been reached. This paper extracts, but also rejects, candidates of epistemic properties for construing an epistemological model of understanding from the writings of epistemologists participating in the current discussion surrounding that state. On the basis of these results, a suggestion is put forward according to which understanding is a non-basic epistemic state of warrant rather than knowledge. It is argued that this (...) move provides a satisfactory conciliatory answer to the central question whether understanding is a factive epistemic state. Some differences between understanding and knowledge are recorded along the way: for instance, that in contrast to knowledge, understanding does not require belief and that, even though neither knowledge nor understanding iterates, so that a subject can both know without knowing that she knows, as well as understanding without understanding that she understands, the reasons for the failure is different.

This paper investigates some epistemic properties that distinguish understanding from knowledge. In particular, the focus is on how to spell out the notion of grasping the relationships between propositions that constitute objectual understanding: what kind of epistemic access is required for grasping to occur and to what extent is the act of grasping voluntary? A modest form of access is suggested as an answer to the first question and a largely negative answer to the second. The worry that my suggestion (...) is too permissive in crediting subjects with understanding is addressed. The results are then finally briefly contrasted to Ernest Sosa’s notion of knowing full well where one contrast precisely concerns the voluntary character of the respective epistemic states. (shrink)
