Rik Peels has once again forcefully argued that ignorance is not equivalent to the lack or absence of knowledge. In doing so, he endeavors to refute the Standard View of Ignorance according to which they are equivalent, and to advance what he calls the “New View” according to which ignorance is equivalent (merely) to the lack or absence of true belief. I defend the Standard View against his new attempted refutation.

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance.

Suppose that knowledge and ignorance are complements in the sense of being mutually exclusive: for person S and fact p, either S knows that p or is ignorant that p. Understood in this way, ignorance amounts to a lack or absence of knowledge: S is ignorant that p if and only if it is not the case that S knows that p. Let us call the thesis that knowledge and ignorance are opposites the “Complement Thesis”. In this article, I discuss (...) its deployment in an ingenious new argument advanced by Alvin Goldman and Erik Olsson (2009) which, if sound, establishes that there is a kind of knowledge that amounts to nothing more than true belief. I rebut their argument and in doing so delineate some important epistemological lessons brought to light by the contrast between ignorance and knowledge. (shrink)

Rik Peels has forcefully argued that, contrary to what is widely held, ignorance is not equivalent to the lack or absence of knowledge. In doing so, he has argued against the Standard View of Ignorance according to which they are equivalent, and argued for what he calls “the New View” according to which ignorance is equivalent (merely) to the lack or absence of true belief. In this paper, I defend the Standard View against Peels’s latest case for the New View.

Deploying distinctions between ignorance of \ and ignorance that \ , and between knowledge of \ and knowledge that \ , I address a question that has hitherto received little attention, namely: what is it to have knowledge of propositions? I then provide a taxonomy of ontological conceptions of the nature of propositions, and explore several of their interesting epistemological implications.

Crispin Sartwell ingeniously defends the provocative thesis that mere true belief suffices for knowledge. In doing so, he challenges one of the most deeply entrenched epistemological tenets, namely that knowledge must be more than mere true belief. Particularly interesting is the way he defends his thesis by appealing to considerations adduced by such prominent epistemologists as William Alston, Laurence BonJour, Alvin Goldman and Paul Moser, each of whom denies that knowledge is merely true belief. In this paper, I argue that (...) the case Sartwell presents for his thesis fails. However, by examining why it fails, we may derive at least four important epistemological lessons: being justified does not entail being able to give a justification; we should distinguish between epistemic justification conceived of as intrinsically conducive to truth and conceived of as extrinsically conducive to truth; we should distinguish between epistemic justification conceived of as an essential criterion of knowledge and conceived of as an accidental criterion of knowledge ; and epistemologists need to specify how the telos of inquiry involves more than the acquisition of true beliefs.Socrates: Then tell me: what definition can we give with the least risk of contradicting ourselves?

ABSTRACTIn this paper, I offer an account of propositional learning: namely, learning that p. I argue for what I call the “Three Transitions Thesis” or “TTT” according to which four states and three transitions between them characterize such learning. I later supplement the TTT to account for learning why p. In making my case, I discuss mathematical propositions such as Fermat's Last Theorem and the ABC Conjecture, and then generalize to other mathematical propositions and to non-mathematical propositions. I also discuss (...) some interesting applications of the TTT, and reply to some noteworthy objections. (shrink)

It is widely held, to the point of being the received interpretation, that Frank Ramsey was the first to defend the so-called Redundancy Theory of Truth in his landmark article ‘Facts and Propositions’ (hereafter ‘FP’) of 1927.1 For instance, A.J. Ayer2 cited this article in the context of arguing that saying that p is true is simply a way of asserting p and that truth is not a real quality or relation. Other holders of the received interpretation, such as George (...) Pitcher,3 J.L. Mackie, 4 Susan Haack,5 A.C. Grayling,6 Nils-Eric Sahlin,7 Richard Kirkham,8 Donald Davidson9 and Michael Lynch10 credit Ramsey with having originated what they call ‘the Redundancy Theory.’ Even an authoritative source such as The Encyclopedia of Philosophy11 attributes this theory to him. What is more, Grover et al.,12 in defending their Prosentential Theory of Truth, claim that their theory is an improvement and development of the Redundancy Theory, which they too attribute to Ramsey.13..

This paper explores and articulates an alternative to the two main approaches that have come to predominate in contemporary philosophical discussionsof skepticism. These we may call the ‘Foil Approach’ and the ‘Bypass Approach’ respectively. On the Foil Approach, skepticism is treated as a problem to be solved, or challenge to be met, or threat to be parried; skepticism’s value, insofar as it is deemed to have one, accrues from its role as a foil contrastively illuminating what is required for knowledge (...) and justified belief. On the Bypass Approach, skepticism is bypassed as a central concern of epistemology. In this paper, I articulate an alternative to both these approaches, one that explores when skepticism is healthy and when it is not. I call it the ‘Health Approach’ to skepticism. (shrink)

Increasingly prominent in the recent literature on the philosophy of perception, Intentionalism holds that sensory experience is inherently intentional, where to be intentional is to be about, or directed on, something. This article explores Intentionalism's prospects as a viable ontological and epistemological alternative to the traditional trinity of theories of sensory experience: the Sense-Datum Theory, the Adverbial Theory, and the Theory of Appearing.

A hitherto unexamined problem for the ‘‘Kantian ideal’’ that one should always treat patients as ends in themselves, and never only as a means to other ends, is explored in this paper. The problem consists of a prima facie conflict between this Kantian ideal and the reality of medical practice. This conflict arises because, at least presently, medical practitioners can only acquire certain skills and abilities by practising on live, human patients, and given the inevitability and ubiquity of learning curves, (...) this learning requires some patients to be treated only as a means to this end. A number of ways of attempting to establish the compatibility of the Kantian Ideal with the reality of medical practice are considered. Each attempt is found to be unsuccessful. Accordingly, until a way is found to reconcile them, we conclude that the Kantian ideal is inconsistent with the reality of medical practice. (shrink)

In this paper, I offer a proof that a disastrous conclusion (namely, that any observation report confirms any hypothesis) may be derived directly from two principles of qualitative confirmation which Carl Hempel called the "Converse Consequence Condition" and the "Entailment Condition." I then discuss three strategies which a defender of the Converse Consequence Condition may deploy to save this principle.

One of the most venerable and enduring intuitions in epistemology concerns the relationship between true belief and knowledge. Famously articulated by Socrates, it holds that true belief does not suffice for knowledge. I discuss a matching intuition about ignorance according to which true belief does not suffice for the absence of ignorance. I argue that the latter intuition undercuts the New View of Ignorance and supports the Standard View of Ignorance.

Searle offers an account of seeing as a conscious state not constituted by the object(s) seen. I focus in this article on his biological case for this thesis, and argue that the biological considerations he adduces neither establish his own position nor defeat a rival object-inclusive view. I show (among other things) that taking seeing to be a biological state is compatible with its being (partially) constituted by the object(s) seen.

How is epistemic justification related to knowledge? Is it, as widely thought, constitutive of knowledge? Is it merely a means to knowledge, or merely a means to something else, such as truth? In a recent article in this journal, Hofmann (2005, Synthese, 146(3), 357–369) addresses these questions in attempting to defend an important argument articulated by Sartwell (1992, The Journal of Philosophy, 89(4), 167–180) and reconstructed and criticized by Le Morvan (2002, Erkenntnis: An International Journal of Analytic Philosophy, 56(2), 151–168). (...) This Sartwellian argument purported to show that, since epistemic justification is of merely instrumental value, it is not constitutive of knowledge. In this paper, I argue that Hofmann’s defense of Sartwell fails, but that its failure brings to light some important lessons concerning the nature of justification and its relationship to truth and knowledge.

I articulate and defend a conception of skepticism inspired by Aristotle’s doctrine of the mean. On it, skepticism is vicious when deficient and when excessive. Virtuous skepticism lies as a mean between these two extremes.

Exploring intentionality from an externalist perspective, I distinguish three kinds of intentionality in the case of seeing, which I call transparent, translucent, and opaque respectively. I then extend the distinction from seeing to knowing, and then to believing. Having explicated the three-fold distinction, I then critically explore some important consequences that follow from granting that there are transparent and translucent intentional states and these intentional states are mental states. These consequences include: first, that existential opacity is neither the mark of (...) intentionality nor of the mental; second, that Sellars has not shown that all intentionality is non-relational; third, that a key Quinean argument for semantic indeterminacy rests on a false premise; fourth, that perceptual experience is intentional on Alston’s Theory of Appearing; fifth, that either some mental causation is more than internal physiological causation or some mental states are epiphenomenal.

In this article, I defend the thesis that selfishness and altruism can be intrapersonal . In doing so, I argue that the notions of intrapersonal altruism and selfishness usefully pick out behavioural patterns and have predictive value. I also argue that my thesis helps enrich our understanding of the prudential, and can subsume some interesting work in economic and psychological theory.

Deploying distinctions between ignorance of a proposition and ignorance that it is true, and between knowledge of a proposition and knowledge that it is true, I distinguish between propositional privacy and factive privacy. While the latter is limited to personal facts, the former encompasses personal falsehoods as well. I argue that propositional privacy is both broader and deeper than factive privacy, and accordingly that conceiving of the nature of privacy in terms of propositional privacy has important advantages over conceiving of (...) it solely in terms of factive privacy. I draw similar lessons with regard to secrecy. (shrink)

In this article I argue that the prevalence of intersubjective disagreement in epistemology poses a serious problem for Epistemic Externalism. I put the problem in the form of a dilemma: either Epistemic Externalism is not a complete account of epistemic justification or it’s implausible to claim that the belief that Epistemic Externalism is true is itself an externalistically justified belief.
