Sense-perception—the awareness or apprehension of things by sight, hearing, touch, smell and taste—has long been a preoccupation of philosophers. One pervasive and traditional problem, sometimes called “the problem of perception”, is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? The present entry is about how these possibilities of error challenge the intelligibility of the phenomenon of (...) perception, and how the major theories of perception in the last century are best understood as responses to this challenge.

David Hume's Enquiry concerning Human Understanding is the definitive statement of the greatest philosopher in the English language. His arguments in support of reasoning from experience, and against the "sophistry and illusion"of religiously inspired philosophical fantasies, caused controversy in the eighteenth century and are strikingly relevant today, when faith and science continue to clash. The Enquiry considers the origin and processes of human thought, reaching the stark conclusion that we can have no ultimate understanding of the physical world, or indeed (...) our own minds. In either sphere we must depend on instinctive learning from experience, recognizing our animal nature and the limits of reason. Hume's calm and open-minded skepticism thus aims to provide a new basis for science, liberating us from the "superstition" of false metaphysics and religion. His Enquiry remains one of the best introductions to the study of philosophy, and his edition places it in its historical and philosophical context. (shrink)

The term ‘emergence’ often causes confusion in science and philosophy, as it is used to express at least two quite different concepts. We can label these concepts _strong_ _emergence_ and _weak emergence_. Both of these concepts are important, but it is vital to keep them separate.

Dieser Band enthält Husserls letzte grosse Arbeit, an der er von 1934 bis 1937 arbeitete. Husserl weist darin die Probleme auf, die seiner Ansicht nach zu der Krise geführt haben, in der die Menschheit der Gegenwart sich befindet. Er verfolgt den Ursprung dieser Krise zurück bis zur Entstehung der neuzeitlichen mathematischen Naturwissenschaften bei Galilei, um aufzuweisen, wie es zu der verhängnisvollen Spaltung des physikalistischen Objektivismus und des transzendentalen Subjektivismus gekommen ist. Die Geschichte der neuzeitlichen Philosophie wird von Descartes über Locke (...) - Berkeley - Hume bis zu Kant verfolgt. Husserl stellt dar, wie es das eigentliche Anliegen der Phänomenologie ist den verhängnisvollen Riss zu überwinden, indem sie den Rückgang zu dem Sinnesfundament vollzieht, das in den Wissenschaften selbst und für diese verborgen bleibt. In diesem Zusammenhang kommt gerade der Wissenschaft vom Menschen, der Psychologie, eine fundamentale Bedeutung zu, allerdings einer Psychologie, die auf der Phänomenologie gründet und von ihren Erkenntnissen ausgeht. Ausser dem erhaltenen Haupttext befinden sich im Husserl-Archiv noch zahlreiche "Forschungsmanuskripte", die im Zusammenhang mit der Krisis-Problematik entstanden sind. Um auch in sie Einblick zu geben wurde eine umfassende Auswahl in Form von Beilagen veröffentlicht, sowie noch einige selbständige Abhandlungen die die Entstehungsgeschichte des Werkes erhellen.

A collection of some of Sellars' lectures and articles from 1951 to 1962.

This authored monograph introduces a genuinely theoretical approach to biology. Starting point is the investigation of empirical biological scaling including their variability, which is found in the literature, e.g. allometric relationships, fractals, etc. The book then analyzes two different aspects of biological time: first, a supplementary temporal dimension to accommodate proper biological rhythms; secondly, the concepts of protension and retention as a means of local organization of time in living organisms. Moreover, the book investigates the role of symmetry in biology, (...) in view of its ubiquitous importance in physics. In relation with the notion of extended critical transitions, the book proposes that organisms and their evolution can be characterized by continued symmetry changes, which accounts for the irreducibility of their historicity and variability. The authors also introduce the concept of anti-entropy as a measure for the potential of variability, being equally understood as alterations in symmetry. By this, the book provides a mathematical account of Gould's analysis of phenotypic complexity with respect to biological evolution. The target audience primarily comprises researchers interested in new theoretical approaches to biology, from physical, biological or philosophical backgrounds, but the book may also be beneficial for graduate students who want to enter this field.

Edition de 150 pages manuscrites laissées par Merleau-Ponty à sa mort et devant constituer les premiers chapitres d'un grand ouvrage intitulé "Le visible et l'invisible". Elles devaient introduire à un nouveau départ pour la pensée philosophique, les concepts fondamentaux de la philosophie moderne étant considérés comme des postulats résultant eux-mêmes déjà d'une interprétation singulière du monde. Le dernier tiers du volume rassemble des notes de travail, éparses, rédigées en vue de l'oeuvre, et qui peuvent en éclairer le sens.

In a number of papers, Hubert Dreyfus and Ronald McIntyre have claimed that Husserl is an internalist. In this paper, it is argued that their interpretation is based on two questionable assumptions: (1) that Husserl's noema should be interpreted along Fregean lines, and (2) that Husserl's transcendental methodology commits him to some form of methodological solipsism. Both of these assumptions are criticized on the basis of the most recent Husserl-research. It is shown that Husserl's concept of noema can be interpreted (...) in a manner that makes his theory far more congenial to a certain type of externalism, but ultimately it is argued that his phenomenological analysis of intentionality entails such a fundamental rethinking of the very relation between subjectivity and world that it hardly makes sense to designate it as being either internalist or externalist.

In his book The Conscious Mind David Chalmers introduced a by now familiar distinction between the hard problem and the easy problems of consciousness. The easy problems are those concerned with the question of how the mind can process information, react to environmental stimuli, and exhibit such capacities as discrimination, categorization, and introspection (Chalmers, 1996, 4, 1995, 200). All of these abilities are impressive, but they are, according to Chalmers, not metaphysically baffling, since they can all be tackled by means (...) of the standard repertoire of cognitive science and explained in terms of computational or neural mechanisms. This task might still be difficult, but it is within reach. In contrast, the hard problem—also known as the problem of consciousness (Chalmers, 1995, 201)—is the problem of explaining why mental states have phenomenal or experiential qualities. Why is it like something to ‘taste coffee’, to ‘touch an ice cube’, to ‘look at a sunset’ etc.? Why does it feel the way it does? Why does it at all feel like anything? Chalmers’s distinction confronts us with a version of the so-called ‘explanatory gap’. On the one hand, we have certain cognitive functions, which can apparently be explained reductively, and on the other hand, we have a number of experiential qualities, which seem to resist this reductive explanation. We can establish that a certain function is accompanied by a certain experience, but we have no idea why that happens, and regardless of how closely we scrutinize the neural mechanisms we don’t seem to be getting any closer at an answer. In his book, Chalmers also distinguished two concepts of mind: a phenomenal concept and a psychological concept. The first captures the conscious aspect of mind: Mind is understood in terms of conscious experience. The second concept understands mind in functional terms as the causal or explanatory basis for behavior.. (shrink)

In the Logical Investigations, Ideas I and many other texts, Husserl maintains that perceptual consciousness involves the intentional “animation” or interpretation of sensory data or hyle, e.g., “color-data,” “tone-data,” and algedonic data. These data are not intrinsically representational nor are they normally themselves objects of representation, though we can attend to them in reflection. These data are “immanent” in consciousness; they survive the phenomenological reduction. They partly ground the intuitive or “in-the-flesh” aspect of perception, and they have a determinacy of (...) character that we do not create but can only discover. This determinate, non-representational stratum of perceptual consciousness also serves as a bridge between consciousness and the world beyond it. I articulate and defend this conception of perceptual consciousness. I locate the view in the space of contemporary positions on phenomenal character and argue for its superiority. I close by briefly arguing that the Husserlian account is perfectly compatible with physicalism (this involves disarming the Grain Problem). (shrink)

: Philosophers in the Indian and Western traditions have developed and defended a range of sophisticated accounts of self-awareness. Here, four of these accounts are examined, and the arguments for them are assessed. Theories of self-awareness developed in the two traditions under consideration fall into two broad categories: reflectionist or other-illumination theories and reflexivist or self-illumination theories. Having assessed the main arguments for these theories, it is argued here that while neither reflectionist nor reflexivist theories are adequate as traditionally formulated (...) and defended, the approaches examined here give important insights for the development of amore adequate contemporary account of self-awareness.

Husserls »Logische Untersuchungen« sind eines der folgenreichsten Werke der neueren Philosophiegeschichte. Mit dem ersten Erscheinen in den Jahren 1900 und 1901 (Max Niemeyer Verlag, Halle/Saale) nimmt jene Schule ihren Anfang, deren Name im Untertitel des zweiten Bandes zum ersten Mal sinnfällig wird: die Phänomenologie. Husserl sah damals in diesem Werk »Versuche zur Neubegründung der reinen Logik und Erkenntnistheorie«, die den Grund zu einem größeren Gedankengebäude zu legen imstande waren. Sie wollten freilich kein bloßes Programm sein, sondern »Fundamentalarbeit an den unmittelbar (...) erschauten und ergriffenen Sachen« darstellen. Die weitere Arbeit an der Ausprägung der phänomenologischen Philosophie führte schon nach wenigen Jahren zu neuen Problemen, zu vertieften Erkenntnissen und zu schärferen Formulierungen. Ihnen trägt die zweite, zum Teil tiefgreifend umgearbeitete Auflage Rechnung, deren Text seither in unveränderter Form immer wieder nachgedruckt wurde. (shrink)

En reposant la question fondamentale de la phénoménologie, et de la philosophie — la question de la donation —, en interprétant celle-ci non plus seulement, selon la pensée traditionnelle de l'Occident, comme apparition dans un monde mais comme l'étreinte invisible de la vie en son propre pathos, la phénoménologie matérielle soulève des problèmes nouveaux et paradoxaux. Trois d'entre eux font l'objet des présentes études : 1 / La matière de la conscience, l'Impression, n'est plus un contenu opaque attendant l'éclaircissement de (...) la forme intentionnelle, ne s'exhibant que dans l'Ek-stase du Temps : elle accomplit la Révélation en elle-même, dans sa chair affective. Au lieu de définir une discipline mineure, vite oubliée, la phénoménologie hylétique — matérielle — dessine la tâche de l'avenir. 2 / La possibilité de connaître la vie invisible donne son sens au problème de la méthode phénoménologique et exige que celle-ci soit repensée entièrement. 3 / La relation à autrui change elle-même de nature si, avant de pouvoir être reconnue au milieu du monde, elle prend corps dans la vie où naissent tous les vivants, l'autre aussi bien que moi-même — si elle est un « pathos-avec ». — Michel Henry —.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that such methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the (...) door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance, and a double-aspect theory of information.

Consciousness fits uneasily into our conception of the natural world. On the most common conception of nature, the natural world is the physical world. But on the most common conception of consciousness, it is not easy to see how it could be part of the physical world. So it seems that to find a place for consciousness within the natural order, we must either revise our conception of consciousness, or revise our conception of nature. In twentieth-century philosophy, this dilemma is (...) posed most acutely in C. D. Broad’s The Mind and its Place in Nature . The phenomena of mind, for Broad, are the phenomena of consciousness. The central problem is that of locating mind with respect to the physical world. Broad’s exhaustive discussion of the problem culminates in a taxonomy of seventeen different views of the mental-physical relation.1 On Broad’s taxonomy, a view might see the mental as nonexistent , as reducible, as emergent, or as a basic property of a substance . The physical might be seen in one of the same four ways. So a four-by-four matrix of views results. At the end, three views are left standing: those on which mentality is an emergent characteristic of either a physical substance or a neutral substance, where in the latter case, the physical might be either emergent or delusive.

The basic question of ontology is “What exists?”. The basic question of metaontology is: are there objective answers to the basic question of ontology? Here ontological realists say yes, and ontological anti-realists say no. (Compare: The basic question of ethics is “What is right?”. The basic question of metaethics is: are there objective answers to the basic question of ethics? Here moral realists say yes, and moral anti-realists say no.) For example, the ontologist may ask: Do numbers exist? The Platonist (...) says yes, and the nominalist says no. The metaontologist may ask: is there an objective fact of the matter about whether numbers exist? The ontological realist says yes, and the ontological anti-realist says no. Likewise, the ontologist may ask: Given two distinct entities, when does a mereological sum of those entities exist? The universalist says always, while the nihilist says never. The metaontologist may ask: is there an objective fact of the matter about whether the mereological sum of two distinct entities exists? The ontological realist says yes, and the ontological anti-realist says no. Ontological realism is often traced to Quine (1948), who held that we can determine what exists by seeing which entities are endorsed by our best scientific theory of the world. In recent years, the practice of ontology has often presupposed an ever-stronger ontological realism, and strong versions of ontological realism have received explicit statements by Fine (this volume), Sider (2001; this volume), van Inwagen (1998; this volume), and others.

It is always risky to make sweeping statements about the development of philosophy, but if one were nevertheless asked to describe 20th century philosophy in broad strokes, one noteworthy feature might be the following: Whereas important figures at the beginning of the century, figures such as Frege and Husserl, were very explicit in their rejection of naturalism (both are known for their rejection of the attempt to naturalize the laws of logic, i.e., for their criticism of psychologism), the situation has (...) changed considerably. Today many philosophers – not the least within analytical philosophy – would subscribe to some form of naturalism. In fact, naturalism is seen by many as the default metaphysical position. If you don’t subscribe to naturalism you must be subscribing to some form of Cartesian substance dualism. Thus, whereas 20 or 30 years ago one might have been inclined to characterize the development of 20th century philosophy in terms of a linguistic turn, a turn from a philosophy of subjectivity to a philosophy of language, it might today be more apt to describe the development in terms of a turn from anti-naturalism to naturalism.

We review some of the work already done around the notion of phenomenal intentionality and propose a way of turning this body of work into a self-conscious research program for understanding intentionality.

L?ambition de cette étude est de présenter succinctement, mais aussi de problématiser un courant nouveau venu dans le paysage philosophique con­temporain, qu?on intitule usuellement « intentionnalité phénomé­nale » ou, plus techniquement, « représentationalisme internaliste » 1 . Ce cou­rant est tout récent. Bien qu?on le fasse parfois remonter à un article de Brian Loar de 1987 (Loar 1987 ; cf. Horgan et Kriegel, à paraître, p. 2 ) , on peut dire qu?il n ?a vraiment pris son essor que dans (...) le courant des années 2000, à travers les travaux, entre autres, de Brian Loar, de Uriah Kriegel, de Terence Horgan et de John Tienson. Je commencerai par en récapituler les grandes thèses, puis j?énumérerai deux problèmes qu?elles soulèvent directement. Enfin, je ferai quelques propositions programmatiques pouvant contribuer à une solution d?ensemble de ces deux problèmes. Comme l?intentionnalité phénoménale est à la pointe de l?actualité des Consciousness Studies et que celles-ci figurent elles-mêmes parmi ce qui se fait de plus innovant et de plus fécond actuellement en philosophie de l?esprit, je pense que ces deux problèmes ont une portée plus générale et qu?ils donneront une bonne idée des difficultés auxquelles est confrontée aujourd?hui la philosophie de l?esprit ? difficultés nouvelles et assez différentes de celles qui caractéri­saient cette dernière il y a encore une quinzaine d?années.

One of Michel Henry’s persistent claims has been that phenomenology is quite unlike positive sciences such as physics, chemistry, biology, history, and law. Rather than studying particular objects and phenomena phenomenology is a transcendental enterprise whose task is to disclose and analyse the structure of manifestation or appearance and its very condition of possibility.

Husserl seems to have devoted roughly equal amounts of energy and pages to the description of perception, judgement, and imagination. By “description,” he meant the analysis of the traits and components of mental states or acts and their objects. As his views changed over the years about the nature of intentionality and philosophy, the descriptive psychology of the Logical Investigations (1900/01) gave way to descriptive programmes in which the objects of perception and of judgement were conceived of in terms of (...) a new, analytic framework; in particular Husserl lost interest in describing the things and processes in the real world that are the objects of perception and judgement and so too in describing their relations to these acts. His new analytic framework, particularly as it applies to perception, has been thoroughly expounded and discussed in the literature. My aim here is to expound Husserl's first descriptions of perception within the framework of the Investigations and to incorporate as far as possible his later descriptive results to the extent that these are separable from his later turn to idealism.

All organised bodies are composed of parts, similar to those composing inorganic nature, and which have even themselves existed in an inorganic state; but the phenomena of life, which result from the juxtaposition of those parts in a certain manner, bear no analogy to any of the effects which would be produced by the action of the component substances considered as mere physical agents. To whatever degree we might imagine our knowledge of the properties of the several ingredients of a (...) living body to be extended and perfected, it is certain that no mere summing up of the separate actions of those elements will ever amount to the action of the living body itself.

In this paper, I want to show that the so-called intentionalist programme, according to which the qualitative aspects of the mental have to be brought back to its intentional features, is doomed to fail. For, pace Brentano, the property that constitutes the main part of such intentional features, i.e., intentionality, is not the mark of the mental, neither in the proper Brentanian sense, according to which intentionality is the both necessary and sufficient condition of the mental, nor in its ‘watered (...) down’ counterpart recently defended by Tim Crane, according to which intentionality is just the necessary condition of the mental. However, this does not mean that being mental is just a heterogenous category. For there may be another mark of the mental, i.e., consciousness, in the phenomenological sense of the property of being experienced. (shrink)

In the introduction to Zur Phänomenologie des inneren Zeitbewusstseins, Husserl remarks that “we get entangled in the most peculiar difficulties, contradictions, and confusions” (Hua X, 4) the moment we seek to account for time-consciousness. I think most scholars of Husserl’s writings on these issues would agree. Attempting to unravel the inner workings of time-consciousness can indeed easily induce a kind of intellectual vertigo. Let us consequently start with some of the basic questions that motivated Husserl’s inquiry.

First, I briefly characterize Dretske’s particular naturalization project, emphasizing his naturalistic reconstruction of the notion of representation. Second, I note some apparent similarities between his notion of representation and Husserl’s notion of intentionality, but I find even more important differences. Whereas Husserl takes intentionality to be an intrinsic, phenomenological feature of thought and experience, Dretske advocates an “externalist” account of mental representation. Third, I consider Dretske’s treatment of qualia, because he takes it to show that his representational account of mind (...) succeeds in naturalizing even the “subjective” features of experience. I claim that Dretske's argument for his account of qualia turns on an ambiguous characterization of qualia. I conclude that he succeeds in naturalizing qualia only if qualia are understood as nonphenomenological features of experience and that he therefore has less to say than he thinks about the subjective life of beings such as us.
