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

What is it like to dream? On an orthodox view, dreams involve misleading sensations and false beliefs. I argue, on philosophical, psychological, and neurophysiological grounds, that orthodoxy about dreaming should be rejected in favor of an imagination model of dreaming. I am thus in partial agreement with Colin McGinn, who has argued that we do not have misleading sensory experiences while dreaming, and partially in agreement with Ernest Sosa, who has argued that we do not form false beliefs while dreaming. (...) Rather, on my view, dreams involve mental imagery and propositional imagination. I defend the imagination model of dreaming from objections. (shrink)

Ernest Sosa has argued that the solution to dream scepticism lies in an understanding of dreams as imaginative experiences – when we dream, on this suggestion, we do not believe the contents of our dreams, but rather imagine them. Sosa rebuts scepticism thus: dreams don’t cause false beliefs, so my beliefs cannot be false, having been caused by dreams. I argue that, even assuming that Sosa is correct about the nature of dreaming, belief in wakefulness on these grounds is epistemically (...) irresponsible. The proper upshot of the imagination model, I suggest, is to recharacterize the way we think about dream scepticism: the sceptical threat is not, after all, that we have false beliefs. So even though dreams don’t involve false beliefs, they still pose a sceptical threat, which I elaborate. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

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.

Brian O'Shaughnessy puts forward a bold and original theory of consciousness, one of the most fascinating but puzzling aspects of human existence. He analyses consciousness into purely psychological constituents, according pre-eminence to its epistemological power; the result is an integrated picture of the conscious mind in its natural physical setting. Consciousness and the World is a rich and exciting book, a major contribution to our understanding of the mind.

A Virtue Epistemology presents a new approach to some of the oldest and most gripping problems of philosophy, those of knowledge and scepticism. Ernest Sosa argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment. By adopting a kind of virtue epistemology in line with the tradition found in Aristotle, Aquinas, Reid, and especially Descartes, he presents an account of knowledge which can be used to shed light on different varieties of scepticism, (...) the nature and status of intuitions, and epistemic normativity.

That conception is orthodox in today’s common sense and also historically. Presupposed by Plato, Augustine, and Descartes, it underlies familiar skeptical paradoxes. Similar orthodoxy is also found in our developing science of sleep and dreaming.[2] Despite such confluence.

Ernest Sosa has proposed two different ways to respond to dreaming skepticism. In this paper I argue that Sosa's first response —which centers on holding that we have no beliefs in dreams— does not appear to be successful against either the hyperbolic or the realistic dreaming skeptic. I also argue that his second attempt to respond to the dreaming skeptic by arguing that perceptual knowledge indeed counts as what he calls "animal knowledge", may succeed but requires us to perform what (...) appears to be some radical surgery on the concept of knowledge; a radical surgery that, as I show, is probably unnecessary to avoid dreaming skepticism. Finally, I sketch some independent considerations why I think that the hyperbolic skeptic's dreaming argument is not acceptable. Ernesto Sosa propone dos maneras de responder al escéptico del sueño. En este ensayo argumento que su primera propuesta, según la cual no tenemos creencias en los sueños, no parece ser una buena respuesta en contra de ninguno de los escepticismos del sueño, de los cuales distingo dos tipos: el hiperbólico y el realista. También argumento que su segunda propuesta para responder al escéptico del sueño, en la que argumenta que el conocimiento perceptual sí cuenta como conocimiento animal, quizá resulte exitosa; sin embargo, ésta requiere llevar a cabo una cirugía radical en el concepto de conocimiento; una cirugía que, como muestro, es probablemente innecesaria para evitar el escepticismo del sueño. Finalmente bosquejo algunas razones independientes por las cuales considero que el argumento del escéptico hiperbólico del sueño no es aceptable. (shrink)

Descartes has often been called the 'father of modern philosophy'. His attempts to find foundations for knowledge, and to reconcile the existence of the soul with the emerging science of his time, are among the most influential and widely studied in the history of philosophy. This is a classic and challenging introduction to Descartes by one of the most distinguished modern philosophers. Bernard Williams not only analyzes Descartes' project of founding knowledge on certainty, but uncovers the philosophical motives for his (...) search. With acute insight, he demonstrates how Descartes' _Meditations _are not merely a description but the very enactment of philosophical thought and discovery. Williams covers all of the key areas of Descartes' thought, including God, the will, the possibility of knowledge, and the mind and its place in nature. He also makes profound contributions to the theory of knowledge, metaphysics and philosophy generally. With a new foreword by John Cottingham. (shrink)

A comprehensive proposal for a conceptual framework for describing conscious experience in dreams, integrating philosophy of mind, sleep and dream research, and interdisciplinary consciousness studies. Dreams, conceived as conscious experience or phenomenal states during sleep, offer an important contrast condition for theories of consciousness and the self. Yet, although there is a wealth of empirical research on sleep and dreaming, its potential contribution to consciousness research and philosophy of mind is largely overlooked. This might be due, in part, to a (...) lack of conceptual clarity and an underlying disagreement about the nature of the phenomenon of dreaming itself. In Dreaming, Jennifer Windt lays the groundwork for solving this problem. She develops a conceptual framework describing not only what it means to say that dreams are conscious experiences but also how to locate dreams relative to such concepts as perception, hallucination, and imagination, as well as thinking, knowledge, belief, deception, and self-consciousness. Arguing that a conceptual framework must be not only conceptually sound but also phenomenologically plausible and carefully informed by neuroscientific research, Windt integrates her review of philosophical work on dreaming, both historical and contemporary, with a survey of the most important empirical findings. This allows her to work toward a systematic and comprehensive new theoretical understanding of dreaming informed by a critical reading of contemporary research findings. Windt's account demonstrates that a philosophical analysis of the concept of dreaming can provide an important enrichment and extension to the conceptual repertoire of discussions of consciousness and the self and raises new questions for future research.

Recently, Ernest Sosa (2007) has proposed two novel solutions to the problem of dream skepticism. In the present paper, I argue that Sosa’s first solution falls prey to what I will refer to as the conditionality problem, i.e., the problem of only establishing a conditional—in this case, if x, then I am awake, x being a placeholder for a condition incompatible with dreaming—in a context where it also needs to be established that we can know that the antecedent holds, and (...) as such can infer the consequent, i.e., I am awake. Sosa’s second solution, in terms of so-called reflective knowledge, is shown to land him in the dilemma of either facing yet another conditionality problem, or violating an internalist constraint that he explicitly grants the skeptic with respect to what kind of factors can be legitimately invoked in our account of how we may know the relevant antecedent. For these reasons, I conclude that Sosa has not solved the problem of dream skepticism. (shrink)

German description: Descartes' Meditationen von 1641 haben bis heute die philosophische Reflexion immer wieder herausgefordert. In diesem Werk geht er von einer Haltung radikalen Zweifels aus, macht dann aber geltend, dass selbst ein ausserster Skeptizismus nicht die fundamentale Wahrheit, dass ich existiere, in Frage stellen kann: ego sum, ego existo. Ausgehend von dieser Gewissheit versucht Descartes, die Grundlagen einer neuen Wissenschaft zu legen. Ursprunglich auf Lateinisch verfasst, wurden die Meditationes 1647 ins Franzosische ubersetzt. Diese Ubersetzung wurde von Descartes selbst durchgesehen (...) und bearbeitet und unterscheidet sich in vielen Nuancen vom lateinischen Original. Diese Ausgabe ist die einzige, die neben der neuen Ubersetzung ins Deutsche den lateinischen Text wie auch die franzosische Version bietet. Erganzt wird sie durch einen umfangreichen Kommentar. Sie eignet sich damit besonders als Arbeitsbuch fur Studenten. (shrink)

In my remarks, I discuss Sosa's attempt to deal with the sceptical threat posed by dreaming. Sosa explores two replies to the problem of dreaming scepticism. First, he argues that, on the imagination model of dreaming, dreaming does not threaten the safety of our beliefs. Second, he argues that knowledge does not require safety, but a weaker condition which is not threatened by dreaming skepticism. I raise questions about both elements of his reply.

The aim is to discover a principle governing the formation of the dream. Now dreaming has an analogy with consciousness in that it is a seeming-consciousness. Meanwhile consciousness exhibits a tripartite structure consisting of understanding oneself to be situated in a world endowed with given properties, the mental processes responsible for the state, and the concrete perceptual encounter of awareness with the world. The dream analogues of these three elements are investigated in the hope of discovering the source of the (...) kinship between dream and consciousness. The dream world proves to be a logically impossible world, limited by nothing more than sheer narratability. The internal world of the dreamer is notable for the limitlessness of the scope allotted to the imagination, together with the presence of two important phenomena encountered in waking consciousness: a measure of interiority, and the positing of a world. Finally, the dream further replicates consciousness in so far as we seem in dreaming concretely to experience our physical surrounds in the form of perceptual imagining. These properties play their part in enabling the dream to be a seeming-consciousness. At the same time they are such as to necessitate its not being consciousness. It is proposed that in the light of these properties, and those composing the state of consciousness, the dream simply is the imagining of consciousness. (shrink)
