Among the epistemological ideas commonly associated with the Descartes of the Meditations, at any rate, is a knowledge-infallibilism. Such an idea was seemingly a vital element in Descartes’s search for truth within that investigative setting: only a true belief gained infallibly could be knowledge, as the Meditations conceived of this. Contemporary epistemologists are less likely than Descartes was to advocate our ever seeking knowledge-infallibility, if only because most are doubtful as to its ever being available. Still, they would agree—in a seemingly Cartesian spirit—that if infallible knowledge was available then it would be a stronger link to truth than fallible knowledge ever manages to be. But this paper argues that infallible knowledge lacks that supposed advantage over fallible knowledge. Indeed, we will see why we should move even further away from the epistemological model at the heart of the Meditations: we should adopt knowledge-minimalism, by conceiving of a belief’s being true as always sufficient for its being knowledge—this, for any belief.

One of contemporary epistemology's more important conceptual challenges is that of understanding the nature of fallibility. Part of why this matters is that it would contribute to our understanding the natures of fallible warrant and fallible knowledge. This article evaluates two candidates – and describes a shared form of failing. Each is concealedly infallibilist. This failing is all-too-representative of the difficulty of doing justice to the notion of fallibility within the notions of fallible warrant and fallible knowledge. The article ends with a proposal for an improved form of conception of fallible warrant and fallible knowledge.

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.

We may usefully distinguish between one’s having fallible knowledge and having a fallibilist stance on some of one’s knowledge. A fallibilist stance could include a concessive knowledge-attribution. But it might also include a questioning knowledge-attribution. Attending to the idea of a QKA leads to a distinction between what we may call closed knowledge that p and open knowledge that p. All of this moves us beyond Elgin’s classic tale of the epistemic capacities of Holmes and of Watson, and towards a way of resolving Kripke’s puzzle about dogmatism and knowing.

Philosophers talk routinely of 'Hume's problem of induction'. But the usual accompanying exegesis is mistaken in a way that has led epistemologists to conceive of 'Hume's problem' in needlessly narrow terms. They have overlooked a way of articulating the conceptual problem, along with a potential way of solving it. Indeed, they have overlooked Hume's own way. In explaining this, I will supplement Hume's insights by adapting Ryle's thinking on knowledge-how and knowledge-that. We will also see why Hume's 'sceptical solution' was a perfectly appropriate response to his 'sceptical argument' -- rather than (as is often thought by analytic epistemologists) a merely descriptive response patently missing the normative sceptical point so strikingly formulated by Hume

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.

Pode o conhecimento de uma dada verdade admitir gradações? Sim, de fato, segundo o gradualismo deste artigo. O artigo introduz o conceito do saber-como que p – isto é, o conceito de saber como é que p. Saber-como que p é claramente gradual – admitindo gradações, dado que se pode saber mais ou menos como é que p. E a vinculação que este artigo faz entre sabercomo que p e saber que p revela que este último tipo de conhecimento também é gradual (mesmo que disfarçadamente). A teoria dos criadores-deverdade [truthmakers] é, então, invocada para enriquecer a análise, e a análise é aplicada às tarefas de fazer sentido do fundacionismo e de barrar uma certa forma de ceticismo. PALAVRAS-CHAVE – Conhecimento. Gradualismo. Absolutismo. Ceticismo. Fundacionismo, Criadores-de-verdade. BSTRACT Can knowledge of a particular truth admit of degrees? Indeed so, according to this paper’s gradualism. The paper introduces the concept of how-knowledge that p – that is, the concept of knowing how it is that p. Howknowledge that p is clearly gradational – admitting of degrees, as one can know more or less of how it is that p. And this paper’s linking of how-knowledge that p with knowledge that p reveals the latter kind of knowledge, too, to be gradational (even if covertly so). Truthmaker theory is then called upon to enrich the analysis, and the analysis is applied to the tasks of understanding foundationalism and of thwarting one form of scepticism. KEY WORDS – Knowledge. Gradualism. Absolutism. Scepticism. Foundationalism. Truthmakers

2. Ginet envisages a person’s fully understanding ‘what the sentence p says’ – which is the person’s fully understanding ‘what is said by one who utters p in normal circumstances in order to assert that p’ (p. 3). The understanding involved is direcError: Illegal entry in bfchar block in ToUnicode CMapted at meaning. It is one’s ‘understanding the parts and the structure of the sentence’ (ibid.). In the next section, I say more about the details of such understanding. First, though, here is how it can help to constitute p’s being self-evident simpliciter (p. 13)

The hypothesis that we are brains in a vat is one which we believe to be false. Could it possibly be true, however? Metaphysical realists accept that our believing it to be false does not entail its falsity. They also accept that if –as brains in a vat –we were to say or think “We are brains in a vat”, then we would be correct. Ever the claimed foe of the metaphysical realist, though, Hilary Putnam argues that the brains‐in‐a‐vat hypothesis cannot be true, in particular that if we were brains in a vat then we could not correctly say or think that we were like that. I will defend metaphysical realism against Putnam's argument

Can we conceive cogently of all knowledge – in particular, all knowledge of truths – as being knowledge-how? This paper provides reasons for thinking not only that is this possible, but that it is conceptually advantageous and suggestive. Those reasons include adaptations of, and responses to, some classic philosophical arguments and ideas, from Descartes, Hume, Peirce, Mill, and Ryle. The paper’s position is thus a practicalism – a kind of pragmatism – about the nature of knowledge, arguing that all knowledge is knowledge-how to act – to do this, to do that. Such a conception can include, too, a distinctive view of the metaphysical relation between knowledge and belief. We see that, contrary to what most contemporary epistemologists say, knowledge need not be a form of belief. Instead, a belief that p can be a way simply of enriching or strengthening knowledge that p. It can do this in a paracticalist way, by allowing one to do more with the knowledge.

Norström has argued that contemporary epistemological debates about the conceptual relations between knowledge-that and knowledge-how need to be supplemented by a concept of technological knowledge—with this being a further kind of knowledge. But this paper argues that Norström has not shown why technological knowledge-that is so distinctive because Norström has not shown that such knowledge cannot be reduced conceptually to a form of knowledge-how. The paper thus applies practicalism to the case of technological knowledge-that. Indeed, the paper shows why Norström’s conception of technological knowledge unintentionally strengthens this proposed form of reduction

When philosophers try to understand the nature of knowledge, they have to confront the Gettier problem. This problem, set out in Edmund Gettier's famous paper of 1963, has yet to be solved, and has challenged our best attempts to define what knowledge is. This volume offers an organised sequence of accessible and distinctive chapters explaining the history of debate surrounding Gettier's challenge, and where that debate should take us next. The chapters describe and evaluate a wide range of ideas about knowledge that have been sparked by philosophical engagements with the Gettier problem, including such phenomena as fallibility, reasoning, evidence, reliability, truth-tracking, context, luck, intellectual virtue, wisdom, conceptual analysis, intuition, experimental philosophy, and explication. The result is an authoritative survey of fifty-plus years of epistemological research - along with provocative ideas for future research – into the nature of knowledge.

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.)
