Ernest Sosa's A Virtue Epistemology, Vol. I is arguably the single-most important monograph to be published in analytic epistemology in the last ten years. Sosa, the first in the field to employ the notion of intellectual virtue – in his ground-breaking ‘The Raft and the Pyramid’– is the leading proponent of reliabilist versions of virtue epistemology. In A Virtue Epistemology, he deftly defends an externalist account of animal knowledge as apt belief, argues for a distinction between animal and reflective knowledge, (...) contends that rational intuition is an intellectual virtue ; and offers responses to dream scepticism, the problem of the criterion and the value problem. Nearly all of these arguments are new, albeit consistent with Sosa's earlier work; that is, consistent with two notable exceptions. First, c ontra Sosa's ‘Replies’ in Ernest Sosa and His Critics, A Virtue Epistemology explicitly contends that safety is not required for animal knowledge. Second, unlike Sosa's Knowledge in Perspective, which arguably construes the intellectual virtues as merely instrumentally valuable, A Virtue Epistemology explicitly contends that the intellectual virtues are instrumentally and constitutively valuable. Best read in conjunction with the above monographs and Epistemic Justification, A Virtue Epistemology is mandatory reading for epistemologists and graduate students in the field. It will rightly set the standard for debates in analytic epistemology for years to come.I will summarize and raise objections to two key conclusions that are unique to A Virtue Epistemology: the ‘kaleidoscope-perceiver’ has animal knowledge but lacks reflective knowledge; unlike the k-perceiver, the ordinary perceiver has reflective knowledge. My objections …. (shrink)

Abilities are in many ways central to what being an agent means, and they are appealed to in philosophical accounts of a great many different phenomena. It is often assumed that abilities are some kind of dispositional property, but it is rarely made explicit exactly which dispositional properties are our abilities. Two recent debates provide two different answers to that question: the new dispositionalism in the debate about free will, and virtue reliabilism in epistemology. This paper argues that both answers (...) fail as general accounts of abilities, and discusses the ramifications of this result. (shrink)

It is a piece of philosophical common sense that belief and knowledge are states. Some epistemologists reject this claim in hope of answering certain difficult questions about the normative evaluation of belief. I shall argue, however, that this move offends not only against philosophical commonsense but also against ordinary common sense, at least as far as this is manifested in the semantic content of the words we use to talk about belief and knowledge. I think it is relatively easily to (...) show with some linguistic tests that ordinary belief and knowledge attributions should be classified aspectually as state descriptions. Hence, the move some epistemologists to deny that belief and knowledge are states threatens to simply change the topic rather than open up answers to difficult questions in epistemology. I do not know fully how to answer the relevant questions about the normative evaluation of belief, but I pursue this critical point here in service of a positive proposal about the general framework in which they should be answered. In brief, the general framework is one which recognizes an important place for what I call state-norms, beside the action-norms which are more familiar from normative theory. And it locates the epistemic norms that apply to beliefs and are relevant for knowledge on the state-norm side of this divide. This turns out to be not only consistent with but indeed to underwrites the philosophical and ordinary common sense that belief and knowledge are states. (shrink)

Omnipotence is the property of being all-powerful; it is one of the traditional divine attributes in Western conceptions of God. This notion of an all-powerful being is often claimed to be incoherent because a being who has the power to do anything would, for instance, have the power to draw a round square. However, it is absurd to suppose that any being, no matter how powerful, could draw a round square. A common response to this objection is to assert that (...) defenders of divine omnipotence never intended to claim that God could bring about logical absurdities. This observation about what is not meant by omnipotence does little, however, to clarify just what is meant by that term. Philosophers have therefore attempted to state necessary and sufficient conditions for omnipotence. (shrink)

Ernest Sosa presents a new approach to the problems of knowledge and scepticism. He argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment. Sosa's virtue epistemology illuminates different varieties of scepticism, the nature and status of intuitions, and epistemic normativity.

Ernest Sosa argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment.

The familiar Vendler-Kenny scheme of verb-types, viz., performances (further differentiated by Vedler into accomplishments and achievements), activities, and states, is too narrow in two important respects. First, it is narrow linguistically. It fails to take into account the phenomenon of verb aspect. The trichotomy is not one of verbs as lexical types but of predications. Second, the trichotomy is narrow ontologically. It is a specification in the context of human agency of the more fundamental, topic-neutral trichotomy, event-process-state.The central component in (...) this ontological trichotomy, event, can be sharply differentiated from its two flanking components by adapting a suggestion by Geoffrey N. Leech and others that the contrast between perfective and imperfective aspect in verbs corresponds to the count/mass distinction in the domain of nouns. With the help of two distinctions, of cardinal count adverbials versus frequency adverbials, and of occurrence versus associated occasion, two interrelated criteria for event predication are developed. Accordingly, Mary capsized the boat is an event predication because (a) it is equivalent to There was at least one capsizing of the boat by Mary, or (b) because it admits cardinal count adverbials, e.g., at least once, twice, three times. Ontologically speaking, events are defined as those occurrences that are inherently countable. (shrink)

This article outlines a conception of perceptual-recognitional abilities. These include abilities to recognize certain things from their appearance to some sensory modality, as being of some kind, or as possessing some property. An assumption of the article is that these abilities are crucial for an adequate understanding of perceptual knowledge. The specific aim here is to contrast those abilities with abilities or competences as conceived in the virtue-theoretic literature, with particular reference to views of Ernest Sosa and John Greco. In (...) the course of the discussion, it is emphasized that the notion of exercising a perceptual-recognitional ability is a success notion: exercising such an ability is nothing less than acquiring knowledge. Even so, the view can make sense of our fallibility. It can also be defended in the face of an objection stemming from consideration of what are here called success-rate abilities. (shrink)

Helen Steward argues that determinism is incompatible with agency itself--not only the special human variety of agency, but also powers which can be accorded to animal agents. She offers a distinctive, non-dualistic version of libertarianism, rooted in a conception of what biological forms of organisation might make possible in the way of freedom.

I argue against traditional virtue epistemology on which knowledge is a success due to a competence to believe truly, by revealing an in-principle problem with the traditional virtue epistemologist’s explanation of Gettier cases. The argument eliminates one of the last plausible explanation of Gettier cases, and so of knowledge, in terms of non-factive mental states and non-mental conditions. I then I develop and defend a different kind of virtue epistemology, on which knowledge is an exercise of a competence to know. (...) I show how the account, while circular, is not viciously so. It explains both how knowledge is a mental state, as well as the relationship between knowledge and justification, including justified false beliefs and Gettier cases. Moreover, although direct virtue epistemology is compatible with many views on the nature of belief, it can explain how knowledge might be metaphysically more fundamental than belief as well.

According to a standard characterization of dispositions, when a disposition is activated by a stimulus, a manifestation of that disposition typically occurs. For example, when flammable gasoline encounters a spark in an oxygen-rich environment, the manifestation of flammability—combustion—occurs. In the dispositions/powers literature, it is common to assume that a manifestation is an effect of a disposition being activated. (I use “disposition” and “power” interchangeably). I address two questions in this chapter: Could all manifestations be effects that involve things acquiring only (...) dispositional properties? And, is thinking of manifestations as contributions to effects preferable to thinking of them as effects? I defend negative responses to both questions. If all properties are dispositional, as the pandispositionalists claim, then any time the activation of a disposition results is something acquiring a new property, it results in something acquiring another disposition. Some worry that a vicious regress ensues (Swinburne, 1980; Bird, 2007a, 2007b: 132-46). While I believe that regress arguments can be addressed, my worry is that, on the pandispositionalist view, manifestations become unobservable. Thinking of manifestations as effects is problematic in cases where what actually occurs is not the kind of effect that the power is a power for, but rather a complex interaction of various powers. Because of this, some prefer to think of manifestations as contributions to effects (Molnar, 2003: 194-8; Mumford, 2009). I argue against this proposal on the ground that it introduces mysterious new entities into our ontology. In the end, the most plausible view is that a single kind of power can have different kinds of effects, some of which involve the instantiation of non-dispositional properties. I proceed as follows. In the first section of this chapter, I show that the philosophical concept of a manifestation is the concept of an effect. In the second section, I argue against the claim that all manifestations involve instantiations of only dispositional properties. In the third section, I argue against the view that manifestations are contributions rather than effects. (shrink)

This paper is roughly in two parts. The first deals with whether know-how is constituted by propositional knowledge, as discussed primarily by Gilbert Ryle (1949) The concept of mind. London: Hutchinson, Jason Stanley and Timothy Williamson (2001). Knowing how. Journal of Philosophy, 98, pp. 411–444 as well as Stephen Hetherington (2006). How to know that knowledge-that is knowledge-how. In S. Hetherington (Ed.) Epistemology futures. Oxford: Oxford University Press. The conclusion of this first part is that know-how sometimes does and sometimes (...) does not consist in propositional knowledge. The second part defends an analysis of know-how inspired by Katherine Hawley’ (2003). Success and knowledge-how. American Philosophical Quarterly, 40, pp. 19–31, insightful proposal that know-how requires counterfactual success. I conclude by showing how this analysis helps to explain why know-how sometimes does and sometimes does not consist of propositional knowledge. (shrink)

The appealing idea that knowledge is best understood as a kind of achievement faces significant criticisms, among them Matthew Chrisman’s charge that the whole project rests on a kind of ontological category mistake. Chrisman argues that while knowledge and belief are states, the kind of normativity found in, for example, Sosa’s famous ‘Triple-A’ structure of assessment is only applicable to performances, end-directed events that unfold over time, and never to states. What is overlooked, both by Chrisman and those he criticizes, (...) is a whole range of projects, those like friendship, health, marriage, and sobriety, where the end is not distinct from our pursuit of it. I suggest that such ‘inner projects’ are in fact stative achievements and thus provide a different sort of model for thinking about knowledge as an achievement. Reconceiving the project along these lines also helps to solve another outstanding problem, the charge that being an achievement is not necessary for knowledge because some knowledge, especially testimonial knowledge, is come by with little or no effort.
