In this impressive second edition of Theory of Knowledge, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the traditional definition of knowledge as justified true belief, Lehrer explores the truth, belief, and justification conditions on the way to a thorough examination of foundation theories of knowledge,the work of Platinga, externalism and naturalized epistemologies, internalism and modern coherence theories, contextualism, and recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes (...) that external factors must be matched by appropriate internal factors to yield knowledge. This match of internal and external factors follows from Lehrer’s new coherence theory of undefeated justification. In addition to doing justice to the living epistemological traditions, the text smoothly integrates several new lines that will interest scholars. Also, a feature of special interest is Lehrer’s concept of a justification game.This second edition of Theory of Knowledge is a thoroughly revised and updated version that contains several completely new chapters. Written by a well-known scholar and contributor to modern epistemology, this text is distinguished by clarity of structure, accessible writing, and an elegant mix of traditional material, contemporary ideas, and well-motivated innovation.

Visual perception is widely taken to present properties such as redness, roundness, and so on. This in turn might be thought to give rise to accuracy conditions for experience, and so content, regardless of which metaphysical view of perception one endorses. An influential version of this argument—Susanna Siegel’s ’Argument from Appearing’—aims to establish the existence of content as common ground between representational and relational views of perception. This goes against proponents of ‘austere’ relationalism who deny that content plays a substantive (...) role in philosophical explanations of conscious perceptual experience. Though Siegel’s argument purports to be neutral with respect to the metaphysics of perception, it relies upon an equivocation between the presentation of property-types and property-instances. Consequently, the argument begs the question against the austere relational view, and so fails to establish the desired conclusion. So while relationalists can and should allow that experiences have accuracy conditions, it does not follow from this that they have contents of any philosophically interesting or significant kind.

The Metaphysics of Knowledge presents the thesis that knowledge is an absolutely fundamental relation, with an indispensable role to play in metaphysics, philosophical logic, and philosophy of mind and language. Knowledge has been generally assumed to be a propositional attitude like belief. But Keith Hossack argues that knowledge is not a relation to a content; rather, it a relation to a fact. This point of view allows us to explain many of the concepts of philosophical logic in terms of (...) knowledge. Hossack provides a theory of facts as structured combinations of particulars and universals, and presents a theory of content as the property of a mental act that determines its value for getting knowledge. He also defends a theory of representation in which the conceptual structure of a content is taken to picture the fact it represents. This permits definitions to be given of reference, truth, and necessity in terms of knowledge. Turning to the metaphysics of mind and language, Hossack argues that a conscious state is one that is identical with knowledge of its own occurrence. This allows us to characterize subjectivity, and, by illuminating the "I"-concept, allows us to gain a better understanding of the concept of a person. Language is then explained in terms of knowledge, as a device used by a community of persons for exchanging knowledge by testimony. The Metaphysics of Knowledge concludes that knowledge is too fundamental to be constituted by something else, such as one's functional or physical state; other things may cause knowledge, but do not constitute it.

Humphreys and Forde (H&F) propose that greater within- category structural similarity makes living things more difficult to name. However, recent studies show that normal subjects find it easier to name living than nonliving things when these are matched across category for potential artefacts. Additionally, at the level of single pixels, visual overlap appears to be greater for nonliving things.

Many philosophers and scientists take perceptual experience, whatever else it involves, to be representational. In ‘The Silence of the Senses’, Charles Travis argues that this view involves a kind of category mistake, and consequently, that perceptual experience is not a representational or intentional phenomenon. The details of Travis’s argument, however, have been widely misinterpreted by his representationalist opponents, many of whom dismiss it out of hand. This chapter offers an interpretation of Travis’s argument from looks that it is argued presents (...) a genuine and important challenge to orthodox representational views of experience. Whilst this challenge may not be insurmountable, it places a substantial burden upon the representationalist to explain not only how experiences come to have the contents that they do, but how those contents come to feature in our conscious mental lives.

The Western world is experiencing a resurgence of interest in the therapeutic potential of psychedelics, most of which are derived from plants or fungi with a history of Indigenous ceremonial use. Recent research has revealed that psychedelic compounds have the potential to address treatment‐resistant depression and anxiety, as well as post‐traumatic stress disorder and addictions. These findings have contributed to the decriminalization of psychedelics in some jurisdictions and their legalization in others. Despite psychedelics’ opaque legal status, numerous companies and individuals (...) are profiting from speculative investments with few, if any, benefits accruing to Indigenous Peoples. In this paper, we suggest that the aptly named “psychedelic renaissance,” like the European Renaissance, is made possible by colonial extractivism. We further suggest that Indigenous philosophical traditions offer alternative approaches to reorient the “psychedelic renaissance” towards a more equitable future for Indigenous Peoples, psychedelic medicines, and all our relations.

The Historical Dictionary of Surrealism relates the history of this movement through a chronology, an introductory essay, a bibliography, and over 600 cross-referenced dictionary entries on persons, circles, and groups who participated in the movement; a global entry on some of the journals and reviews they produced; and a sampling of major works of art, cinema, and literature.

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial or phenomenological structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical scepticism about the spatiality of auditory experience, it is as richly spatial as (...) visual experience—and in some ways even more so. By carefully considering the spatiality and boundedness of audition, along with how sounds or their sources are experienced as occurring within the surrounding acoustic environment, we can gain a better understanding of (i) our auditory experience of space and (ii) the conditions for the existence of spatial sensory fields in general in a way that does not privilege vision over the other senses.

This book derives from a 1993 National Endowment for the Humanities Summer Institute on Knowledge, Teaching, and Wisdom. The Institute took place at the University of California, Berkeley, and was co-directed by Keith Lehrer and Nicholas D. Smith. The aims of the Institute were several: we sought to reintroduce wisdom as a topic of discussion among contemporary philosophers, to undertake an historical investigation of how and when and why it was that wisdom faded from philosophical view, and to ask (...) how contemporary epistemological theories might apply to the obviously related subjects of teaching and wisdom. In recruiting participants, Lehrer and Smith put the greatest emphasis on those with professional interests in epistemology and the history of philosophy, of the ancient Greeks especially ancient Greek philosophy (because in the writings all three subjects of the Institute were explicitly related and discussed). But in addition to these two groups, some effort was made also to include others, with academic specializations in a variety of fields other than epistemology and the history of philosophy, to ensure that a broad perspective could be achieved in our discussions. To an obvious extent, the papers in this book reflect the recruitment emphases and variety. They also testify to the extent that the Institute managed to bring life to our subjects, and to raise very old questions in a contemporary context. (shrink)

I will be concerned with only one problem about truth which is raised by the diversity of religions which exist in the world. The problem is this: many religions claim to state truths about the nature of the universe and human destiny which are important or even necessary for human salvation and ultimate well-being. Many of these truths seem to he incompatible; yet there is no agreed method for deciding which are to he accepted; and equally intelligent, informed, virtuous and (...) holy people belong to different faiths. It seems, therefore, that a believing member of any one tradition is compelled to regard all other traditions as holding false beliefs and therefore as not leading to salvation. Since each faith forms a minority of the world's population, all religious believers thus seem committed to saying that most intelligent, virtuous and spiritually devoted people cannot know the truth or attain salvation. This is a problem, because it is in tension with the belief, held by many traditions, that the supremely real being is concerned for the salvation of all rational creatures. How can this he so if, through no fault of their own, most creatures cannot come to know the truth and thereby attain salvation? (shrink)

The dual role of olfaction in both smelling and tasting, i.e. flavour perception, makes it an important test case for philosophical theories of sensory individuation. Indeed, the psychologist Paul Rozin claimed that olfaction is a “dual sense”, leading some scientists and philosophers to propose that we have not one, but two senses of smell: orthonasal and retronasal olfaction. In this paper I consider how best to understand Rozin’s claim, and upon what grounds one might judge there to be one or (...) two distinct olfactory modalities. I conclude that while Rozin may be right that humans have dual occurrences of an olfactory ‘sense’, the concept of a sense-modality, and hence the ‘sense’ of smell, is ambiguous between two different notions: a physiological sensory channel and an experiential modality, along the lines suggested by J. J. Gibson. Furthermore, recognising that these are complementary rather than competing conceptions of a sense-modality enables the formulation of a powerful ‘dual-concept’ framework for posing and addressing questions concerning the complex architecture of human multisensory experience.

I argue that the co-existence of omnipotence, omniscience, and total evil forms an inconsistent triad. An omniscient being will know what it is like for anyone to feel pain, and since pain is undesirable, will not freely create pains which it would have to share. An omnipotent being would choose to be rational, and a purely rational being would choose what it believes to be good. It would in fact choose to be of supreme value, and thus would necessarily contain (...) all compossible values, including those of friendship and love. Therefore an omnipotent omniscient being cannot be evil. (shrink)

Because every single one of us will die, most of us would like to know what—if anything—awaits us afterward, not to mention the fate of lost loved ones. Given the nearly universal vested interest we personally have in deciding this question in favor of an afterlife, it is no surprise that the vast majority of books on the topic affirm the reality of life after death without a backward glance. But the evidence of our senses and the ever-gaining strength of (...) scientific evidence strongly suggest otherwise. -/- In The Myth of an Afterlife: The Case against Life after Death, Michael Martin and Keith Augustine collect a series of contributions that redress this imbalance in the literature by providing a strong, comprehensive, and up-to-date casebook of the chief arguments against an afterlife all in one place. Divided into four separate sections, this essay collection opens the volume with a broad overview of the issues, as contributors consider the strongest available evidence as to whether or not we survive death—in particular the biological basis of all mental states and their grounding in brain activity that ceases to function at death. Next contributors consider a host of conceptual and empirical difficulties that confront the various ways of "surviving" death—from bodiless minds to bodily resurrection to any form of posthumous survival. Then essayists turn to internal inconsistencies between traditional theological conceptions of an afterlife—Heaven, Hell, karmic rebirth—and widely held ethical principles central to the belief systems undergirding those notions. In the final section, authors offer critical evaluations of the main types of evidence for an afterlife. -/- Fully interdisciplinary, The Myth of an Afterlife: The Case against Life after Death brings together a variety of fields of research to make that case, including cognitive neuroscience, philosophy of mind, personal identity, philosophy of religion, moral philosophy, psychical research, and anomalistic psychology. As the definitive casebook of arguments against life after death, this collection is required reading for any instructor, researcher, and student in philosophy, religious studies, and theology. It is sure to raise provocative issues new to readers, regardless of background, from those who believe fervently in the reality of an afterlife to those who do not or are undecided on the matter.

Previous research on associative learning has uncovered detailed aspects of the process, including what types of things are learned, how they are learned, and where in the brain such learning occurs. However, perceptual processes, such as stimulus recognition and identification, take time to unfold. Previous studies of learning have not addressed when, during the course of these dynamic recognition processes, learned representations are formed and updated. If learned representations are formed and updated while recognition is ongoing, the result of learning (...) may incorporate spurious, partial information. For example, during word recognition, words take time to be identified, and competing words are often active in parallel. If learning proceeds before this competition resolves, representations may be influenced by the preliminary activations present at the time of learning. In three experiments using word learning as a model domain, we provide evidence that learning reflects the ongoing dynamics of auditory and visual processing during a learning event. These results show that learning can occur before stimulus recognition processes are complete; learning does not wait for ongoing perceptual processing to complete. (shrink)

While researching my 2001 book on sickle cell disease, I became aware of the politics of pain. In that malady—a painful disorder associated with African Americans and characterized by frequent infections and recurring painful “crises”—the politics of pain recognition and adequate relief intersect not only with drug concerns, but also with American racial politics. One cannot understand fully the history of sickle cell patients without understanding politics on two levels: the macropolitics of race in America and the micropolitics of medicinal (...) encounters. How these two kinds of politics collided in clinical decision-making about diagnosis, treatment, and pain management has long been a focus of my scholarship—not... (shrink)

Explores ten questions that consider if religious beliefs can survive in the scientific age.

David Hume’s arguments against believing reports of miracles are shown to be very weak. Laws of nature, I suggest, are best seen not as exceptionless rules but as context-dependent realizations of natural powers. In that context miracles transcend the natural order not as "violations" but as intelligible realizations of a divine supernatural purpose. Miracles are not parts of scientific theory but can be parts of a web of rational belief fully consistent with science. (edited).

In his account of visual perception, Thomas Reid describes visible figure as both ‘real and external’ to the eye and as the ‘immediate object of sight’. These claims appear to conflict with Reid's direct realism, since if the ‘immediate’ object of vision is also its direct object, then sight would be perceptually indirect due to the role of visible figure as a perceptual intermediary. I argue that this apparent threat to Reid's direct realism may be resolved by understanding visible figure (...) as the set of geometrical properties that holds between an object's visible surfaces and some particular perspective or point of view. On this relational interpretation of visible figure, and once an ambiguity over the use of the term ‘object’ is resolved, Reid's account of vision is both epistemically and perceptually direct, as well as consistent with his account of the other senses and doctrine of signs.

How did the French Revolution become thinkable? Keith Michael Baker, a leading authority on the ideological origins of the French Revolution, explores this question in his wide-ranging collection of essays. Analyzing the new politics of contestation that transformed the traditional political culture of the Old Regime during its last decades, Baker revises our historical map of the political space in which the French Revolution took form. Some essays study the ways in which the revolutionaries' break with the past was (...) prepared by competition between agents and critics of absolute monarchy to control the cultural resources and political meanings of French sought before 1789 to reconstitute their body politic; and by the invention of 'public opinion' as a new form of political authority displacing notions of 'representation', 'constitution', 'sovereignty' - and of 'the French Revolution' itself - the ambiguities, tensions, and contradictions that were to drive the revolutionary dynamic in subsequent years. The result is a substantial and unified set of studies, stimulating renewed reflection on one of the central themes in modern European history. (shrink)

What is it about you in virtue of which you are having the thoughts you are now having? The answer will no doubt make some appeal to the state your brain is now in. Most philosophers, however, claim that this is only part of the answer; many of the facts that determine your thoughts lie outside your skin. This view is called externalism, and in this book Keith L. Butler argues that, contrary to widespread philosophical opinion, externalism is very (...) implausible. Through critical evaluation of a vast amount of philosophical work on the subject, Butler shows that externalism faces problematic epistemological implications (regarding self-knowledge and knowledge of the external world), and problematic metaphysical implications (regarding mental causation). Moreover, externalism derives no support from an appeal to the cognitive sciences. The controversy generated by this book bears on issues in the philosophy of mind, language, science, and epistemology. It is required reading for serious students and professionals concerned with these areas of philosophy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:JOHN PASSMORE AND HUME'S MORAL PHILOSOPHY1 A quarter century ago, the message undergraduates absorbed about David Hume was as an extremely favourable one. He was the great precursor of logical empiricism and so his philosophy, at least in its main lines, must be nearer the mark than that of any other of the great names. Hume had discovered the right view of causation. He had exposed and banished school (...) metaphysics. He had rightly drawn attention to the problem of induction. He had discovered the isought gap and revealed the practical impotence of reason in the face of the passions. But for his weight problem, he could have walked on water. Those were the circumstances in which I first read John Passmore's book on Hume. Because he was plainly not, like many of Hume's critics, an apologist for Thomism or any of Hegel's offspring, his work could not be dismissed on the grounds of parti pris. It was 2 a shock, therefore, to find him, in Hume's Intentions, presenting an image of Hume a considerable distance this side of idolatry. Passmore's critical and, for its time, boldly unfashionable appraisal is to be admired, taken to heart, and extended. Hume's Intentions concentrates on Hume's philosophy of the understanding. It takes up strands of that philosophy and points to their inherent implausibility and mutual incompatibility. Yet these problems also vitiate other parts of Hume's position. In this paper I attempt to introduce the Passmorian method of reasoning into what are nowadays the moral subjects. Let me remind you of the structure of Passmore's book: it does not mount a consecutive argument so much as take up, tease out, and display one or other leading element in the Humean philosophy. Thus we have chapters on Hume as an enthusiast for the 110. moral (that is, human, or social) sciences, as a critic of traditional Aristotelian logic, as a developer of more suitable methods for scientific advance, as a positivist, a phenomenalist, an associationist theoretician in psychology, and a sceptic. We learn as we read that in these respects Hume is not consistent. Principles which he espouses, principally negative and sceptical principles, lead to conclusions too extreme to suit his major purposes. Accordingly, they must not be pressed to their proper conclusions. Hume's philosophy of the study must be abandoned rather than actually taken seriously. Thus, for example: in methodology, Hume insists that reason cannot yield results in the contingent and fallible natural and human sciences. This should lead him to the view that any scientific hypothesis which goes beyond immediate experience is, so far as reason goes, as good, or as bad, as any other. But he recoils from this, distinguishing sensible men from the foolish and superstitious on the basis of the regularity and consistency of the experiences on which the wise rely. Yet as Passmore points out, on Hume's principles, the preference for regularity and consistency cannot be more than a prejudice. Prejudices do not admit of any genuinely rational defence. There is real substance to the superiority claimed for the wise. Again, consider Hume's positivism. He offers a beguilingly short way with nonsense, especially learned and theological nonsense. School metaphysics and superstition (i.e. Christianity) are to be banished by the use of the impressions and ideas test: When you come upon a word whose meaning you would discover, ask if it refers to an impression or an idea. If to an impression, well and good, its meaning is to be found in present experience. If to an idea, ask from which impression (or impressions) the idea did (or could) Ill, derive. If you cannot find any suitable impressions, the idea is chimerical, and is to be excised from thought as a pathological intruder. This procedure produces most satisfactorily negative results when it comes to the Trinity and the sacraments, or essence, inherence, substantial form, and such metaphysical extravagances. Unhappily the very same procedure, the impressions and ideas test, also wrecks the foundations of Hume's own thought. As Passmore makes sure we remember, the test robs Hume of the resources with which to account for substance and... (shrink)

This paper investigates the idea of clinical autonomy. Whilst there is a considerable literature on moral autonomy there is very little on clinical autonomy except as a sociological phenomenon. Using the results of interviews with Community Psychiatric Nurses in England, the three main theories that they have about clinical autonomy are examined. It is argued that there are substantial problems with these theories and an alternative way of understanding clinical autonomy is proposed, the idea of contractual space.

Is science our most precious possession or has our culture elevated science into a false idol? Is technology a useful servant or a malign genie? These questions are at the centre of the 'science wars' currently being waged over the role and future of science and technology in our society. This balanced selection of a variety of perspectives on the hotly contested role of science and technology in contemporary society will clarify this vital debate for both specialists and non-specialists.

In a 2022 paper, Hamami claimed that the orthodox view in mathematics is that a proof is rigorous if it can be translated into a derivation. Hamami then developed a descriptive account that explains how mathematicians check proofs for rigor in this sense and how they develop the capacity to do so. By exploring introductory texts in computability theory, we demonstrate that Hamami’s descriptive account does not accord with actual mathematical practice with respect to computability theory. We argue instead for (...) an alternative account in which imagination, anticipation, and interpretations of natural language play roles in establishing mathematical rigor. (shrink)

Amidst the return of military personnel from post-9/11 conflicts, a construct describing the readjustment challenges of some has received increasing attention: moral injury. This term has been variably defined with mental health professionals more recently conceiving of it as a transgression of moral beliefs and expectations that are witnessed, perpetrated, or allowed by the individual. To the extent that morality is a system of conceptualizing right and wrong, individuals’ moral systems are in large measure developmentally and socially derived and interpreted. (...) Thus, in seeking to provide care and aid in reintegration for combat veterans, it is necessary to consider communities that have contributed to an individual’s formation and that might have participated in the interpretation of his/her suffering. This can take many forms, but given that morality is often complexly intertwined with issues of religion, faith, and spirituality for many individuals, and recognizing that much of the current focus on moral injury is emanating out of healthcare contexts, we devote particular attention to how chaplains might be more intentionally engaged in healthcare systems such as the Veterans Health Administration to provide non-judgmental, person-centered, culturally-relevant care rooted in communities of practice to veterans with moral injury.

A number of researchers have focused on the distinction between upward counterfactuals that simulate a better reality and downward counterfactuals that simulate a worse reality. In this chapter the authors will discuss the important aspects of a model (Markman and McMullen 2003) that attempts to explain how the very same counterfactual can engender dramatically different affective reactions. According to the model, the consequences of simulation direction are moderated by what we have termed simulation mode--relatively stronger tendencies to engage in reflective (...) versus evaluative processing. In turn, the authors will describe how the interaction between simulation direction and mode produces important consequences for affect, motivation, and behavior. (shrink)

The idea that there are five senses dates back to Aristotle, who was one of the first philosophers to examine them systematically. Though it has become conventional wisdom, many scientists and philosophers would argue that this idea is outdated and inaccurate. Indeed, they have given many different answers to this question, ranging from just three (the number of different kinds of physical energy we can detect) to 33 or more senses. Perhaps surprisingly, the issue remains controversial, partly because it is (...) not clear exactly what should count as a ‘sense’. Should proprioception, balance and kinaesthesis, amongst others, be considered additional senses? And if so, how do we figure out how many senses we really have? -/- (Published in Turkish under the title ‘Çok Duyumlu Algi’). (shrink)
