Edmund Gettier's 1963 verdict about what knowledge is not has become an item of philosophical orthodoxy, accepted by philosophers as a genuine epistemological result. It assures us that - contrary to what Plato and later philosophers have thought - knowledge is not merely a true belief well supported by epistemic justification. But that orthodoxy has generated the Gettier problem - epistemology's continuing struggle to understand how to accommodate Gettier's apparent result within an improved conception of knowledge. In this book, Stephen Hetherington argues that none of epistemology's standard attempts to solve that problem have succeeded: he shows how subtle yet fundamental mistakes - regarding explication, methodology, properties, modality, and fallibility - have permeated those responses to Gettier's challenge. His fresh and original book outlines a new way of solving the problem, and an improved grasp of Gettier's challenge and its significance is the result. In a sense, Plato can now embrace Gettier.

Sceptics standardly argue that a person lacks knowledge due to an inability to know that some dire possibility is not being actualised in her believing that p. I argue that the usual sceptical inventory of such possibilities should include one's possibly having had some freedom in forming one's belief that p. A sceptic should conclude that wherever there might have been some such freedom, there is no knowledge that p. (This is not to say that sceptics would be correct in that conclusion. It is just to say that the usual sceptical way of thinking should welcome the possibility of some such belief-freedom as much as it routinely welcomes the possibilities of dreaming and of evil demons.)

Scepticism about external world knowledge is frequently claimed to emerge from Descartes’s dreaming argument. That argument supposedly challenges one to have some further knowledge — the knowledge that one is not dreaming that p — if one is to have even one given piece of external world knowledge that p. The possession of that further knowledge can seem espe-cially important when the dreaming possibility is genuinely Cartesian (with one’s dreaming that p being incompatible with the truth of one’s accompany-ing belief that p). But this paper shows why that Cartesian use of that possi-bility is not at all challenging. It is because that putative sceptical challenge reduces to a triviality which is incompatible with the sceptic’s having de-scribed some further piece of knowledge which is needed, if one is to have the knowledge that p.

This dissertation questions two central presuppositions of traditional normative epistemology. The first, , is that the epistemologist's epistemic subject is a person--that the epistemologist is discussing you. The second, , is that the epistemologist's methodology is one of investigative detachment--that in principle his investigation is impartially of each of us. ;My arguments rely on a distinction between the epistemic subject qua epistemologist and qua non-epistemologist. The former is interested in cognitively supporting epistemic principles, such as principles of justification, and he sees such support as necessary to his having justification or knowledge. The latter doesn't see himself this way. The one epistemic subject can proceed in either way, though not in the one context. I connect this distinction with recent work on epistemic levels. ;Against , I argue that the epistemologist can conceive of his epistemic subject only as an epistemic subject qua epistemologist. Whether he is considering what it takes for the epistemic subject to possess knowledge or justification, or whether he is considering what it takes to deprive the epistemic subject of knowledge or justification, he has to conceive of that epistemic subject as being, in that context, an epistemologist. I call this methodological limitation epistemological imperialism. ;Against , I argue that the epistemologist can conceive of the epistemic subject as the subject of the sceptic's argument, and hence as lacking knowledge or justification, only if the subject is a disembodied epistemologist . This metaphysical move converts the epistemological imperialism into what I call epistemological projectivism. Traditional normative epistemology requires the epistemologist to project his own mind onto his epistemic subject; his own mind is his epistemic subject

How might epistemology build upon its past and present, so as to be better in the future? Epistemology Futures takes bold steps towards answering that question. What methods will best serve epistemology? Which phenomena and concepts deserve more attention from it? Are there approaches and assumptions that have impeded its progress until now? This volume contains provocative essays by prominent epistemologists, presenting many new ideas for possible improvements in how to do epistemology. Contributors: Paul M. Churchland, Catherine Z. Elgin, Richard Feldman, A. C. Grayling, Stephen Hetherington, Christopher Hookway, Hilary Kornblith, Mark Kaplan, William G. Lycan, Adam Morton, Jonathan M. Weinberg, Linda Zagzebski.

Despite the problems students often have with the theory of knowledge, it remains, necessarily, at the core of the philosophical enterprise. As experienced teachers know, teaching epistemology requires a text that is not only clear and accessible, but also capable of successfully motivating the abstract problems that arise.In Knowledge Puzzles, Stephen Hetherington presents an informal survey of epistemology based on the use of puzzles to illuminate problems of knowledge. Each topic is introduced through a puzzle, and readers are invited to work their own ways toward a solution. Hetherington’s light and undogmatic style encourages class discussion and independent thought rather than the memorization of “book” answers.Covering all of the most important epistemological issues, informed by classical and contemporary literature, and rich in probing questions and suggestions for further readings, Knowledge Puzzles is a pedagogical breakthrough. Whether it is used as a main text or supplement, this lucid and engaging text will be welcomed by both teachers and students.

I argue that Goodman's puzzle of grue at least poses no real challenge about inductive inference. By drawing on Stove's characterisation of Hume's characterisation of inductive inference, we see that the premises in an inductive inference report experienced impressions; and Goodman can be interpreted as posing a real challenge about inductive inference only if we treat an epistemic subject's observations more as logical contents and less as experienced impressions. So, even though the grue puzzle was effective against its stated logicist targets, it is not thereby an enduring difficulty regarding experience's ability to impart epistemic justification via inductive evidence.
