The function of REM, or any other stage of sleep, can currently only be conjectured. A rational evaluation of the role of REM in memory processing requires systematic testing of hypotheses that are optimally derived from a complete synthesis of existing knowledge. Our view is that the large number of studies supporting a relationship between REM-related brain activity and memory is not easily explained away. [Vertes & Eastman].

The Walker model raises a number of questions, particularly about the nature of the sleep states involved in consolidation enhancement. While REM sleep, Stage 2 sleep, and Stage 3/4 sleep have been implicated in procedural learning, we still do not understand which types of learning are involved with specific sleep states. Several possible ideas for future research are suggested.

Sleep has long been a topic of fascination for artists and scientists. Why do we sleep? What function does sleep serve? Why do we dream? What significance can we attach to our dreams? We spend so much of our lives sleeping, yet its precise function is unclear, in spite of our increasing understanding of the processes generating and maintaining sleep. We now know that sleep can be accompanied by periods of intense cerebral activity, yet only recently has experimental data started (...) to provide us with some insights into the type of processing taking place in the brain as we sleep. There is now strong evidence that sleep plays a crucial role in learning and in the consolidation of memories. Once the preserve of psychoanalysts, 'dreaming' is now a topic of increasing interest amongst scientists. With research into sleep growing, this volume is both timely and valuable in presenting a unique study of the relationship between sleep, learning, and memory. It brings together a team of international scientists researching sleep in both human and animal subjects. Aimed at researchers within the fields of neuroscience, cognitive neuroscience, psychiatry, and neurology, this book will be an important first step in developing a full scientific understanding of the most intriguing state of consciousness.

Quentin Smith offers powerful arguments against the New Theory of Reference propounded by leading thhinkers in the philosophy of language. Smith defends the tensed theory of time and argues that the simultaneity is absoltue, basing this position on the theory that all propositions exist in time. Using detailed propostitions and a theory of cognitive significance, he introduces an alternative interpretation of reference that will be relevant to metaphysicians, philosophers of science and philosophers of language and may come to (...) be recognised as the definitive statement on the tensed theory of time.

Of all the major philosophical works, Kant's Critique of Pure Reason is one of the most rewarding, yet one of the most difficult. Norman Kemp Smith's Commentary elucidates not only textural questions and minor issues, but also the central problems which arise, he contends, from the conflicting tendencies of Kant's own thinking. Kemp Smith's Commentary continues to be in demand with Kant scholars, and it is being reissued here with a new introduction by Sebastian Gardner to set it (...) in its contemporary context. (shrink)

WE must first state the subject of our inquiry and the faculty to which it belongs: its subject is demonstration and the faculty that carries it out demonstrative science.

This title presents a comprehensive guide to interpretative phenomenological analysis (IPA) which is an increasingly popular approach to qualitative inquiry taught to undergraduate and postgraduate students today.

A ‘lottery belief’ is a belief that a particular ticket has lost a large, fair lottery, based on nothing more than the odds against it winning. The lottery paradox brings out a tension between the idea that lottery beliefs are justified and the idea that that one can always justifiably believe the deductive consequences of things that one justifiably believes – what is sometimes called the principle of closure. Many philosophers have treated the lottery paradox as an argument against the (...) second idea – but I make a case here that it is the first idea that should be given up. As I shall show, there are a number of independent arguments for denying that lottery beliefs are justified. (shrink)

The essay constructs an ontological theory designed to capture the categories instantiated in those portions or levels of reality which are captured in our common sense conceptual scheme. It takes as its starting point an Aristotelian ontology of “substances” and “accidents”, which are treated via the instruments of mereology and topology. The theory recognizes not only individual parts of substances and accidents, including the internal and external boundaries of these, but also universal parts, such as the “humanity” which is an (...) essential part of both Tom and Dick, and also “individual relations”, such as Tom’s promise to Dick, or their current handshake.

DIVBased on a series of lectures delivered in 1840, Thomas Carlyle’s On Heroes, Hero-Worship, and the Heroic in History considers the creation of heroes and the ways they exert heroic leadership. From the divine and prophetic to the poetic to the religious to the political, Carlyle investigates the mysterious qualities that elevate humans to cultural significance. By situating the text in the context of six essays by distinguished scholars that reevaluate both Carlyle’s work and his ideas, David (...) Sorensen and Brent Kinser argue that Carlyle's concept of heroism stresses the hero’s spiritual dimension. In Carlyle’s engagement with various heroic personalities, he dislodges religiosity from religion, myth from history, and truth from “quackery” as he describes the wondrous ways in which these “flowing light-fountains” unlock the heroic potential of ordinary human beings. /div.

Deleuze argued that a fundamental mutation in the concept of time occurred in Kant. In antiquity, the concept of time was subordinated to the concept of movement: time was a ‘measure’ of movement. In Kant, this relation is inverted: time is no longer subordinated to movement but assumes an autonomy of its own: time becomes "the pure and empty form" of everything that moves and changes. What is essential in the theory of time is not the distinction between objective ‘clock (...) time’ (or physical time) and the subjective experience of ‘time consciousness,’ since both of them measure movements, whether the movement of extensive objects or intensive states. What is fundamental is rather the relation between time and movement, since time can only assume its own concept when it ceases to be subordinate to movement, whether that movement is objective or subjective. This article examines how Kant inverted the relation between time and movement, and how Deleuze’s own theory of time builds on Kant’s revolution and extends it further. (shrink)

Epistemic permissivism is the view that it is possible for two people to rationally hold incompatible attitudes toward some proposition on the basis of one body of evidence. In this paper, I defend a particular version of permissivism – unacknowledged permissivism (UP) – which says that permissivism is true, but that no one can ever rationally believe that she is in a permissive case. I show that counter to what virtually all authors who have discussed UP claim, UP is an (...) attractive view: it is compatible with the intuitive motivations for permissivism and avoids a significant challenge to permissivism: the arbitrariness objection.

According to the standard story of action, a story that can be traced back at least to David Hume , actions are those bodily movements that are caused and rationalized by a pair of mental states: a desire for some end, where ends can be thought of as ways the world could be, and a belief that something the agent can just do, namely, move her body in the way to be explained, has some suitable chance of making the world (...) the relevant way. Bodily movements that occur otherwise aren't actions, they are mere happenings. (shrink)

My concern in this paper is with the claim that knowledge is a mental state – a claim that Williamson places front and centre in Knowledge and Its Limits. While I am not by any means convinced that the claim is false, I do think it carries certain costs that have not been widely appreciated. One source of resistance to this claim derives from internalism about the mental – the view, roughly speaking, that one’s mental states are determined by one’s (...) internal physical state. In order to know that something is the case it is not, in general, enough for one’s internal physical state to be a certain way – the wider world must also be a certain way. If we accept that knowledge is a mental state, we must give up internalism. One might think that this is no cost, since much recent work in the philosophy of mind has, in any case, converged on the view that internalism is false. This thought, though, is too quick. As I will argue here, the claim that knowledge is a mental state would take us to a view much further from internalism than anything philosophers of mind have converged upon. (shrink)

In this paper, I offer reasons for thinking that two prominent sceptical arguments in the literature – the underdetermination-based sceptical argument and the closure-based sceptical argument – are less philosophically interesting than is commonly supposed. The underdetermination-based argument begs the question against a non-sceptic and can be dismissed with little fanfare. The closure-based argument, though perhaps not question-begging per se, does rest upon contentious assumptions that a non-sceptic is under no pressure to accept.

In this article, I foreground the role of relationality in Husserl’s later reflections on ethics and self-constitution, with a particular interest in Husserl’s account of sacrifice. I exposit how Husserl’s account of self-constitution and the conflict of absolute values between competing vocations offers a solution to Brentano’s rendering of the obligation to “choose the best among the ends attainable.” I explore the numerous instances in which Husserl uses the parent-child relation to illustrate the absolute value of our relation to an (...) individual and how this absolute value triumphs over other seemingly rational maxims. Although problematic in several ways, Husserl’s account of motherhood grounds his notion of self-constitution in particular relations with others, rather than in a general category of nation or humanity. I conclude by considering how his emphasis on phenomenological constitution and his approach to value and sacrifice may inform future projects in phenomenological relational ethics. (shrink)

In a promising working note to the Visible and Invisible, Merleau-Ponty proposes that we understand Being according to topological space – relations of proximity, distance, and envelopment – and move away from an image of Being based on homogeneous, inert Euclidean space. With reference to treatments of cross-sensory perception, color-blindness, and the concept of quale or qualia, I seek to rehearse this shift from Euclidean to topological Being by illustrating how modern science confines color itself to a Euclidean model of (...) color space. I discuss “being as Object” in Merleau-Ponty’s later work before showing how color, and indeed all perception, is reduced to being as Object in the form of “quale”. Next, I address discussions in Merleau-Ponty’s work and contemporary research to illustrate how synesthesia and so-called color-blindness are rendered abnormal by this objectified being of color. Merleau-Ponty’s reading of synesthesia follows directly from his rejection of quale, and his use of color perception serves as a rejection of solipsism. With appeal to his proposed topological model of Being, I conclude by recognizing the problematic nature of synesthesia and color-blindness as being ontological, not psychological.Dans une note de travail, à mon sens décisive, du Visible et l’Invisible, Merleau-Ponty propose que l’on comprenne l’Être à partir de l’espace topologique – relations de proximité, distance et enveloppement – allant à l’encontre d’une l’image de l’Être fondée sur un espace euclidien homogène et inerte. En faisant référence aux traitements de la perception synesthésique, au daltonisme et au concept de quale ou qualia, j’essayerai de décrire ce passage de l’Être euclidien à l’Être topologique en montrant que la science moderne finit par confiner la couleur dans un modèle euclidien d’espace-couleur. J’examinerai « l’Être-objet » dans les derniers écrits de Merleau-Ponty avant de montrer comment la couleur, et plus en général la perception, est réduite à être comme un Objet dans la forme d’un « quale ». Ensuite, en examinant les analyses merleau-pontiennes et les recherches contemporaines, je montrerai comment la synesthésie et le daltonisme sont donc considérés comme anormaux à partir de cette objectivation de la couleur. La lecture que Merleau-Ponty donne de la synesthésie est la conséquence directe de son refus du quale, et l’utilisation qu’il fait de la perception des couleurs sert comme un refus du solipsisme. En faisant appel au modèle topologique de l’Être qu’il propose, je conclurai en constatant que la nature problématique de la synesthésie et du daltonisme est ontologique et non pas psychologique.In una nota di lavoro al Visibile e l’invisibile, Merleau-Ponty propone di comprendere l’Essere a partire da uno spazio topologico – secondo le relazioni di prossimità, distanza e avvolgimento – e abbandona l’immagine di un Essere fondato su uno spazio omogeneo, inerte, euclideo. Facendo riferimento ai trattamenti per le percezioni sinestetiche, al daltonismo e al concetto di quale o qualia, si cercherà di provare questo passaggio da un Essere euclideo a uno topologico, illustrando quanto la scienza moderna tenda a ridurre il concetto stesso di colore a un modello euclideo di spazio-colore. Si esaminerà l’“Essere-oggetto” degli ultimi lavori di Merleau-Ponty, mostrando come il colore, e in realtà la percezione tout court, vengano ridotti a oggetto nella forma di “quale”. Infine, si esaminerà l’opera merleau-pontiana e la ricerca contemporanea al fine di illustrare quanto la sinestesia e il daltonismo siano resi anormali da questa oggettivazione dell’essere del colore. L’interpretazione merleau-pontiana della sinestesia deriva proprio dal suo rifiuto del quale, e il suo uso della percezione del colore funge da rifiuto del solipsismo. Ricorrendo al modello topologico di Essere elaborato da Merleau-Ponty, si conclude riconoscendo che il problema della sinestesia e del daltonismo è, a tutti gli effetti, ontologico e non psicologico.

“The contemporary” is a phrase in frequent use in artworld discourse as a placeholder term for broader, world-picturing concepts such as “the contemporary condition” or “contemporaneity”. Brief references to key texts by philosophers such as Giorgio Agamben, Jacques Rancière, and Peter Osborne often tend to suffice as indicating the outer limits of theoretical discussion. In an attempt to add some depth to the discourse, this paper outlines my approach to these questions, then explores in some detail what these three theorists (...) have had to say in recent years about contemporaneity in general and contemporary art in particular, and about the links between both. It also examines key essays by Jean-Luc Nancy, Néstor García Canclini, as well as the artist-theorist Jean-Phillipe Antoine, each of whom have contributed significantly to these debates. The analysis moves from Agamben’s poetic evocation of “contemporariness” as a Nietzschean experience of “untimeliness” in relation to one’s times, through Nancy’s emphasis on art’s constant recursion to its origins, Rancière’s attribution of dissensus to the current regime of art, Osborne’s insistence on contemporary art’s “post-conceptual” character, to Canclini’s preference for a “post-autonomous” art, which captures the world at the point of its coming into being. I conclude by echoing Antoine’s call for artists and others to think historically, to “knit together a specific variety of times”, a task that is especially pressing when presentist immanence strives to encompasses everything.

There is an extensive literature on time travel in both philosophy and physics. Part of the great interest of the topic stems from the fact that reasons have been given both for thinking that time travel is physically possible—and for thinking that it is logically impossible! This entry deals primarily with philosophical issues; issues related to the physics of time travel are covered in the separate entries on time travel and modern physics and time machines. We begin with the definitional (...) question: what is time travel? We then turn to the major objection to the possibility of backwards time travel: the Grandfather paradox. Next, issues concerning causation are discussed—and then, issues in the metaphysics of time and change. We end with a discussion of the question why, if backwards time travel will ever occur, we have not been visited by time travellers from the future. (shrink)

The new tenseless theory of time, Developed primarily by j j c smart and d h mellor, States that tensed sentence-Utterances cannot be translated by tenseless ones but nevertheless have tenseless truth conditions. Smart and mellor infer from this that the tenseless theory of time is true. The author argues, However, That the rules of use of tensed sentence-Utterances entail that these utterances also have tensed truth conditions. This implies that the tensed theory of time is true.

There is no doubt science is currently suffering from a credibility crisis. This thought-provoking book argues that, ironically, science's credibility is being undermined by tools created by scientists themselves. Scientific disinformation and damaging conspiracy theories are rife because of the internet that science created, the scientific demand for empirical evidence and statistical significance leads to data torturing and confirmation bias, and data mining is fuelled by the technological advances in Big Data and the development of ever-increasingly powerfulcomputers. Using a wide (...) range of entertaining examples, this fascinating book examines the impacts of society's growing distrust of science, and ultimately provides constructive suggestions for restoring the credibility of the scientific community.

As conceived by analytic philosophers ontology consists in the application of the methods of mathematical logic to the analysis of ontological discourse. As conceived by realist philosophers such as Meinong and the early Husserl, Reinach and Ingarden, it consists in the investigation of the forms of entities of various types. The suggestion is that formal methods be employed by phenomenological ontologists, and that phenomenological insights may contribute to the construction of adequate formal-ontological languages. The paper sketches an account of what (...) might be involved in this new discipline, an account which is illustrated in application to the formal-ontological problems raised by negative states of affairs.

In this book, Canadian scholar David Geoffrey Smith reflects on over thirty years of research and teaching in the human sciences, including education. Written between 1986 and 2018, the essays are organized around three themes: Hermeneutics and the Human Sciences; The Poststructuralist Turn; Globalization and Its Discontents; East/West Encounters and the Search for Wisdom. As a historical guide through the defining discourses in the human sciences, this volume could well serve as an introductory text for graduate students in education (...) and other cognate disciplines like nursing, recreation and cultural studies. The writing can be described as a form of meditative praxis, while the emphasis on interculturality addresses issues in literacy, pedagogy, politics, critical thinking, teacher education, and cultural healing from a geopolitical perspective, drawing on insights from both Western and Eastern traditions and the author's personal experience of being born in China and raised in Central Africa (Northern Rhodesia/Zambia).

Hume's account of belief is understood to be inspired by allegedly incompatible motivations, one descriptive and expressing Hume's naturalism, the other normative and expressing Hume's epistemological aims. This understanding assumes a particular way in which these elements are distinct: an assumption that I dispute. I suggest that the explanatory-naturalistic aspects of Hume's account of belief are not incompatible with the normative-epistemological aspects. Rather, at least for some central cases of belief formation that Hume discusses at length, S's coming to believe (...) thatpcan be explained in a way that vindicates S's belief thatp. (shrink)

The book has a twofold content and aim: on the one hand, it offers a radical critique of the modern world, and on the other, it seeks to expound timeless wisdom. And the second end presupposes the first: for so long as we have not "broken through the barrier of scientistic belief" as the subtitle has it, that timeless wisdom-that veritable sophia perennis-remains inaccessible.

Explores the basic forms of responsibility that we willingly assume and the collaborative fulfillment that we find in each.

For more than 60 years, Chomsky has been an intellectual Colossus bestriding the worlds of language, philosophy, and the cognitive sciences, and focusing attention on the whole field and emphasizing the crucial importance of domains overlooked by the mainstream. One such area is the study of first‐language acquisition. This chapter considers “atypical acquisition” to cover two conceptually related situations. First, it covers a variety of cases where there is an obvious “poverty of the stimulus” in that children either receive or (...) perceive no linguistic input at the essential early stages referred to as critical periods. Second, it covers where there is rather the opposite situation. The chapter presents atypicality in language acquisition that stems from the learner's atypical neurological profile rather than environmental or input properties. It focuses on Developmental Language Disorder, Autism Spectrum Disorder, and the case of the polyglot‐savant Christopher to exemplify atypical acquisition. (shrink)
