This study is an exploration of the place of perspectivism in the philosophy of Henri Bergson. His work is compared with that of Thomas Nagel in terms of the mutual concern of these two philosophers to reconcile our increasingly objecti vist and impersonal understanding of reality with the perspectival apprehension of the world that living and conscious beings instantiate. It argues that Bergson's philosophy of time holds the key both to comprehending and to balancing the demands made upon us by (...) these conflicting interests. It is seldom that Bergson's name is thought of in this connection, his concerns more often than not being identified with some thesis about time, movement, or vital forces. One purpose of the present work, therefore, is to contest this interpretive slant, not merely by offering an alternative image of Bergson, but also by critically exploring his employment of perspectivism (both positive and negative). We pursue this goal through the double strategy of both unravelling the inconsistencies in Bergson's· treatment of perspective and separating his own argument from the multitude of myths, opinions, and interpretations, sympathetic and unsympathetic, that have arisen around what is currently understood by "Bergsonism". In retrieving his thought from such philosophical ghettoes as "vitalism," "spiritualism," and "psychologism," we will argue for a Bergsonian perspectivism which ultimately resides in a thesis propounding the primacy of perception. One consequence of this is the demotion of memory's importance within his thought. Not that the orthodox image of Bergsonism that retains the privileged place of memory is wrong. Rather, we argue that there is enough in Bergson's peculiar picture of perception to obviate the need for memory in his philosophy, and, moreover, that it is actually more Bergsonian that memory should be so discharged.

Philosophers of mind have distinguished (and sometimes conflated) various qualities. This article tries to sort things out.

The dominant position in current debates on the mind-body problem is some version of physicalism, according to which the mind is reducible to the brain and mental phenomena are ultimately explainable in physical terms. But there seems to be an explanatory gap between physicalistic descriptions of neuronal processes and the subjectivity of conscious experience. Some dualists conclude that, therefore, consciousness must be ontologically distinct from any physical properties or entities. This article introduces and argues for a different perspective on these (...) issues, namely, an epistemological dualism - a nonreductive position which is neither a version of physicalism nor an ontological dualism. It is argued that Kant holds this epistemological dualism implicitly as a consequence of his critical epistemology. On the one hand, he stresses the explanatory gap between the mental and the physical. On the basis of his theory of subjectivity set out in the Transcendental Deduction, Kant provides an explanation for why the gap cannot be closed empirically, as the physicalist promises. On the other hand, in his criticism of Descartes’ dualism in the Paralogismschapter, Kant argues that an ontological conclusion on the basis of this epistemological gap is unjustified even though physicalism is explanatory inadequate to account for consciousness. Thus, this epistemological dualism can be seen as an original third way between physicalist reductionism and ontological dualism. (shrink)

This thesis inquires into our ‘human nature’ through an interdisciplinary approach that considers some of the radical changes in intellectual thought at those key points in Western culture in which this concept has been centrally deployed. The broad historical sweep that this study covers finds the preoccupation with defining who we are and what we are capable of inextricably linked with the focus, at most of the pivotal moments examined, on a dominant impulse to conceive human beings as moral creatures.

“Naturalized epistemology” is a recent attempt to transform the theory of knowledge into a branch of natural science. Traditional epistemologists object to this proposal on the grounds that it eliminates the distinctively philosophical content of epistemology. In this thesis, I argue that traditional philosophers are justified in their reluctance to accept naturalism, but that their ongoing inability to refute it points to deeper problems inherent in traditional epistemology. I establish my thesis first by critiquing three versions of naturalism, showing that (...) each version either fails to implement its objectives consistently or starts from dubious objectives. “Optimistic naturalism” attempts to use naturalistic methods to give positive answers to traditional epistemological questions (such as by affirming that our beliefs can be justified). This fails because the form of traditional questions requires the concept “belief,” a concept that I argue naturalistic methodology cannot countenance (because of the severe constraints of naturalistic semantic theory). “Pessimistic naturalism,” the version advocated by Quine, is more consistent with naturalistic methodology, but fails because hidden behind its conclusions are assumptions (such as the underdetermination thesis) that cannot themselves be naturalized in the full context of scientific evidence. A final attempt to naturalize epistemology, deflationary naturalism, dispenses with traditional questions entirely, urging that the terms “knowledge” and “justification” be taken as mere pragmatic devices whose use can, nevertheless, be studied scientifically. Curiously, this view fails to take account of important facts about the actual use of those terms, as studied by psychologists. In the end, despite problems with each of these versions, traditional philosophers can learn something from their encounter with naturalism. In the course of showing how various naturalistic doctrines cannot themselves be naturalized, I identify the flaws in traditional epistemology (such as its reliance on a priorism, and its resulting inability to articulate a workable empirical foundationalist theory of justification) that make naturalism harder to challenge. These flaws must be corrected if philosophers are to preserve the autonomy of their discipline. (shrink)

Metaphysicians eager to engage with substantive, thoughtful, and provocative issues will be happy with John Heil’s From an Ontological Point of View. The book represents not only a sustained defence of a specific metaphysical theory, but also of a specific way of doing metaphysics. Put ontology first, Heil urges us, in order to remember that the original fascination of metaphysics wasn’t the question ‘what must the world be like in order to correspond neatly to our use of language?’, but rather (...) the altogether more fundamental ‘what must the world be like?’.

A central issue in philosophy and neuroscience is the problem of unified visual consciousness. This problem has arisen because we now know that an object's stimulus features (e.g., its color, texture, shape, etc.) generate activity in separate areas of the visual cortex (Felleman & Van Essen, 1991). For example, recent evidence indicates that there are very few, if any, neural connections between specific visual areas, such as those that correlate with color and motion (Bartels & Zeki, 2006; Zeki, 2003). So (...) how do unified objects arise in visual consciousness? Some neuroscientists propose that neural synchrony is the mechanism that binds an object's features into a unity (e.g., see Crick, 1994; Crick & Koch, 1990; Engel, 2003; Roelfsema, 1998; Singer, 1996; von der Malsburg, 1996, 1999). I argue, on both empirical and philosophical grounds, that neural synchrony fails to explain the unity of visual consciousness. (shrink)

This dissertation explores issues in the philosophy of psychology and metaphysics through the lens of the emotion of disgust, and its corresponding property, disgustingness. The first chapter organizes an extremely large body of data about disgust, imposes two constraints any theory must meet, and offers a cognitive model of the mechanisms underlying the emotion. The second chapter explores the evolution of disgust, and argues for the Entanglement thesis: this uniquely human emotion was formed when two formerly distinct mechanisms, one dedicated (...) to monitoring food intake and protecting against poisons, the other dedicated to protecting against parasitic infection, where driven together until they became functionally integrated. The third chapter explores the sorts of acquisition mechanisms that could give rise to the patterns of individual and cultural level variation we find with disgust elicitors. It argues for the Empathic Acquisition thesis, which holds that one important route for the social acquisition and transmission of disgust elicitors is linked to empathic recognition of facial expressions of the emotion. The fourth chapter builds on the Entanglement thesis, and embeds the emotion of disgust in gene-culture coevolutionary theory and the tribal instincts hypothesis. The Co-opt thesis is defended, which maintains that disgust was co-opted to play an important role in our moral psychology, particularly in our cognition of social norms and ethnic boundary markers. In doing so, however, it brings to bear many features initially linked to poisons and parasites. This explains the puzzling and troublesome character of moral judgments linked to disgust. After shifting gears from psychology to metaphysics, the fifth chapter recasts the Humean tradition of projectivism in the terminology of cognitive science. Using examples such as disgust, I argue that a psychologized projectivism is able to make sense of the idea that some properties are projected onto the world, rather than found there to begin with. The final chapter criticizes three other accounts of the property of disgustingness, two inspired by functionalism in the philosophy of color, one inspired by fittingness accounts in metaethics. I argue that none provide nearly as satisfactory account of the property as the psychologized projectivism articulated previously. (shrink)

To date, there is no universal and coherent theory concerning the nature or the function of time. Furthermore, important and unresolved controversies raging within both philosophy and the natural sciences apparently indicate that there is little hope of constructing a single, unified theory. Even so-called "folk" theories of time, embedded within different cultural traditions, show no common elements, and therefore can not provide a pre-theoretical description of time, towards which an explanatory framework could be constructed. This lack of consensus indicates (...) that the concept as it is currently being used is ill defined, and, at the very least, needs to be considerably revised. The conceptual disarray surrounding time has aided and abetted the arguments of certain thinkers, especially Ricoeur, working within the phenomenological tradition who make de principe claims that there can not be a single theory of time. My intention is not to try and to produce a concept of time that was capable of unifying all these different elements. Rather, Ricoeur's arguments and those of others working in the phenomenological tradition dissatisfied me. I believed that their arguments were informed by a myopic, muddled and positively 19th Century understanding of the scientific project. Hence, my aim is to show that Ricoeur's claim will not stand up to scrutiny, and that there are no principled arguments against the possibility of a unified theory of time. We examine the major arguments against unification in general, and also with particular reference to theories of time, such as Husserlian phenomenology, conventionalism, instrumentalism, anti-reductive positions in general, as well as the specific problem of reducing subjective experience to objective description. We demonstrate that none of these objections constitutes a watertight a priori argument against a unified theory of time. Furthermore, we demonstrate that recent developments in the philosophy of science and the philosophy of mind have made such a unified theory a plausible goal. We argue that post-positivist philosophy of science, with its emphasis on research programmes, the co-evolution of theories and super-empirical rational support, opens the way for new types of evidence to be brought to bear on questions about time. Also, recent developments in the brain sciences mean that a neurologically plausible and fully naturalised analysis of our experience of time is being developed. Although much work in this direction has begun, we argue that it is fragmented, partly through the limitations of our current knowledge, but more particularly through an inadequate background of coherent philosophical thought. This has lead both philosophers and scientists to attempt grand metaphysical answers to muddled philosophical questions which threaten the progress which natural science and the philosophy of science have offered in the second half of the twentieth century.

Frank Jackson’s knowledge argument is a very influential piece of reasoning that seeks to show that colour experiences constitute an insoluble problem for science. This argument is based on a thought experiment concerning Mary. She is a vision scientist who has complete scientific knowledge of colours and colour vision but has never had colour experiences. According to Jackson, upon seeing coloured objects, Mary acquires new knowledge that escapes her complete scientific knowledge. He concludes that there are facts concerning colour experiences (...) that scientific knowledge can neither describe nor explain. Specifically, these facts involve the occurrence of certain non-physical properties of experiences that he calls qualia. The present research considers whether a plausible formulation of the hypothesis that science can accommodate colour experiences is threatened by a version of the knowledge argument. The specific formulation of this problem has two motivations. Firstly, before investigating whether the knowledge argument raises a problem for the claim that science can account for colour experiences, we need a plausible formulation of this claim. I argue that the idea that science can accommodate colour experiences can be formulated as the modest reductionism hypothesis. Roughly speaking, this is the hypothesis that a science that can be explanatory interfaced with current physics of ordinary matter can account for conscious experiences. Secondly, an unintelligible premise figures in Jackson’s version the knowledge argument. Namely, it is assumed that Mary possesses a complete scientific knowledge. Nevertheless, the type of strategy involved in Jackson’s argument can be used to target modest reductionism. By considering contemporary psychophysics and neuroscience, I characterise Mary’s scientific knowledge. First, this characterisation is intelligible. In fact, it is elaborated on the basis of descriptions and explanations of colour experiences involved in current physics and neuroscience. Second, a supporter of modest reductionism can assume that the scientific knowledge ascribed to Mary might account for colour experiences. The main conclusion of the present research is that our version of the knowledge argument fails to threaten the modest reductionism hypothesis. In fact, I endorse what can be called the “two ways of thinking” reply to the knowledge argument. According to this response, the knowledge argument shows that there are different ways of thinking about colour experiences. One way of thinking is provided by scientific knowledge. The other way of thinking is provided by our ordinary conception of colour experiences. However, the existence of these two ways of thinking does not imply the existence of facts and properties that escape scientific knowledge. It might be the case that the ordinary way of thinking about colour experience concerns facts and properties described and explained by science. The principal conclusion of the research results from two investigations. The first line of research aims to reveal and evaluate the implicit assumptions that figure in the knowledge argument. The main body of the research is dedicated to this task. The principal result of this investigation is that the knowledge argument must rely on an account of introspective knowledge of colour experiences. I argue that an inferential model of introspection provides such account. On this model, Mary’s capacity to hold beliefs about her colour experiences when she sees coloured objects requires her mastery of colour concepts. The second main investigation seeks to justify the two ways of thinking strategy. As many opponents and supporters have recently started to realise, this strategy might be charged with being ad hoc. I offer a distinctive justification of this reply to the knowledge argument. Assuming the account of introspection mentioned above, the existence of visual recognitional colour concepts might justify this strategy. A person possesses these concepts when she is able to determine the colours of objects simply by having visual experiences. (shrink)

This thesis is an examination and critique of naturalistic representational theories of phenomenal character. Phenomenal character refers to the distinctive quality that perceptual and sensational experiences seem to have; it is identified with 'what it is like' to undergo experiences. The central claims of representationalism are that phenomenal character is identical with the content of experience and that all representational states, bearing appropriate relations to the cognitive system, are conscious experiences. These claims are taken to explain both how conscious experiential (...) states arise and their nature. After examining the desiderata for naturalistic explanations, I argue that theories which ascribe nonconceptual content to experiences are the most plausible versions of representationalism. Further, causal covariation and teleological theories yield distinctive and interesting representationalist positions, hence, they become the focus of this study. To assess representationalism, I investigate whether all differences in phenomenal character can be correlated with differences in content. I claim that a useful distinction can be drawn between implicit and explicit content, which allows one to best describe the phenomena of perfect and relative pitch. I then argue that ambiguous figures show that two experiences can have the same content but different phenomenal character. I explicate the Inverted Earth hypothesis and claim that to identify content and phenomenal character, representationalists either have to condone the possibility of philosophical zombies, or hold that people lack authoritative first-person knowledge of their current experiences. Both these positions are unpalatable. Finally, I argue that representationalists cannot ascribe contents to experiences of novel colours to account for their phenomenal character. I also question, in light of dissociation phenomena, whether there is one distinctive relationship that all experiences bear to the cognitive system. I conclude that phenomenal character cannot be identical with the type of content under investigation, and that naturalistic representationalist theories cannot fully explain conscious experience.

In the first chapter of this paper I focus on the general overview of Occam's Razor, and develop several interpretations and adaptations of Occam's Razor as a principle of simplicity. In the second chapter I apply these different interpretations in the Physicalism/Dualism debate, and critically assess the validity of these implementations of Occam's Razor in philosophy of mind. In the final chapter I give an overview of my discussion thus far, and make assertions about what my paper means for the (...) usage of Occam's Razor's as a whole. (shrink)

A lengthy reply to 13 critical discussions of _Meaning in Life: An Analytic Study_ collected in an e-book and reprinted from the _Journal of Philosophy of Life_.

In this thesis, I argue that physicalism should be understood to be the view that mental properties are realized by physical properties. In doing this, I explore what the realization relation might be. Since realization is the relation that should help us formulate physicalism, I suggest that the theoretical role of realization consists in explaining some of the things that physicalists wish to explain. These are: How are mental properties metaphysically necessitated by physical properties? How are mental properties causally efficacious? (...) A theory of realization should provide resources for answering these questions. Having identified the theoretical role of realization, I discuss several theories of realization, but then focus on the subset view of realization. According to the subset view, a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P. I argue that the realization relation as it is formulated by the subset view is a promising candidate to play the theoretical role that I want realization to play. I then investigate how this theoretical role is occupied. In doing so, I provide a general metaphysical framework that the defenders of the subset view can appeal to. This framework specifies in what ways properties are related to their causal powers. Discussing some problems that the subset view faces, I propose my own version of the subset view. I argue that a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P, and P is more fundamental than Q. Thanks to the requirement that a realized property is less fundamental than its realizers, two things that the original version of the subset view cannot explain are guaranteed: first, fundamental properties are not realized; second, arbitrary conjunctions of properties do not realize their conjuncts. By showing how a theory of realization can help us explain some of the things that physicalists typically wish to explain, I also show that a non-reductive variety of physicalism does not face the problems that it is commonly thought to face.

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.

In this dissertation, I evaluate whether conceivability can be regarded as an epistemic guide to possibility.

It is now conventional wisdom that conscious experience — or in Nagel’s canonical characterization, “what it is like to be” for an organism — is what makes the mind-body problem so intractable. By the same token, our current conceptions of the mind-body relation are inadequate and some conceptual development is urgently needed. Our overall aim in this paper is to make some progress towards that conceptual development. We first examine a currently neglected, yet fundamental aspect of consciousness. This aspect is (...) the spontaneity of consciousness, by which we mean its inner plasticity and inner purposiveness. We then sketch a “neurophenomenological” framework for thinking about the relationship between the spontaneity of consciousness and dynamic patterns of brain activity as studied in cognitive neuroscience. We conclude by proposing that the conscious mentality of sentient organisms or animals is active and dynamic, and that this “enactive” conception of consciousness can help us to move beyond the classical dichotomy between materialism and dualism.

My dissertation explores some issues of Aristotle’s philosophy, regarding the functionalist interpretation developed by Hilary Putnam and Martha C. Nussbaum as a valuable starting point. In Chapter One, I analyze some families of interpretations of Aristotle’s “psuchology” proposed in the second half of the 20th century in the context of the philosophy of mind. I show how some aspects of Aristotle’s thought, which are correctly grasped by the dualistic as well as by the physicalist interpretation, are later resumed and harmonized (...) by functionalism into a coherent doctrine. In Chapter Two it is worth to set out an analysis of Aristotle’s hylomorphism. I take into account homonymy, which is traditionally conceived as being in conflict with hylomorphism. I show not only how homonymy is rather a consequence of hylomorphism, but also how it allows to highlight that hylomorphism, if properly conceived, should be regarded as an ontological thesis with predicative consequences. In this regard, I suggest my own definition of hylomorphism. In Chapter Three, I take into account Aristotle’s final causation, comparing it with contemporary naturalism. I hold that teleology demonstrates Aristotle’s anti-reductionism and, in particular, the fact that he attributes causal efficacy to natural forms and ends. I criticize functionalism for having regarded Aristotle’s formal and final causes as being just explanatory, whereas, on the contrary, Aristotle conceives such explanatory character to derive from their genuine causal role. I formulate my own position, which I label as “logical compatibilism”. I hint at how the functional analysis of living organism may establish some points of contact between Aristotle’s and Darwin’s analysis. I recognize that functionalism correctly grasps the functional roles Aristotle attributes to matter and form and that it translates such an account in a valuable philosophical doctrine. Nevertheless, functionalism confines itself within the framework of contemporary philosophy of mind and fails to comprehend Aristotle’s anti-reductionist naturalism as regards biological life and nature in general.

La ricerca empirica nelle scienze cognitive può essere di supporto all’indagine filosofica sullo statuto ontologico e epistemologico dei concetti mentali, ed in particolare del concetto di credenza. Da oltre trent’anni gli psicologi utilizzano il test della falsa credenza per valutare la capacità dei bambini di attribuire stati mentali a se stessi e a agli altri. Tuttavia non è stato ancora pienamente compreso né quali requisiti cognitivi siano necessari per passare il test né quale sia il loro sviluppo. In questo articolo (...) analizzo l’impatto della funzione esecutiva e delle abilità linguistiche per la capacità di passare il test della falsa credenza. Suggerisco che tale abilità dipende dall’acquisizione di un nuovo formato rappresentazionale per codificare la falsità degli stati mentali altrui. I dati in nostro possesso non permettono tuttavia di precisare la natura di tale formato. (shrink)

This article aims to provide a brief overview of mental causation problem and its current proposed solutions. Indeed, mental causation turns out as one of the most difficult philosophical conundrums in contemporary philosophy of mind. In the first two sections, we offer an outline of the problem and the philosophical debate about it, and show that mental causation problem is pivotal within the contemporary philosophy of mind. In the third section, we focus on the most popular models of mental causation, (...) namely Kim's and Davidson's accounts, also discussing the objections raised against them. In the final section, we take into consideration some recent proposals poised to solve the mental causation problem, including powerism. Given the logical and metaphysical plausibility of almost all these different options, our conclusion is that mental causation is still an open problem and it is far from being resolved. (shrink)

Charles Siewert's _The Significance of Consciousness_ contends that most philosophers and psychologists who have written about "consciousness" have neglected a crucial type or aspect that Siewert calls "phenomenal consciousness" and tries carefully to define. The present article argues that some philosophers, at least, have not neglected phenomenal consciousness and have offered tenable theories of it.

According to the standard view, the causal process connecting a past representation and its subsequent recall involves intermediary memory traces. Yet Bertrand Russell and Ludwig Wittgenstein held that since the physiological evidence for memory traces isn't quite conclusive, it is prudent to come up with an account of memory causation-referred to as nmemic causation—that manages without the stipulation of memory traces. Given mnemic causation, a past representation is directly causally active over a temporal distance. I argue that the stipulation of (...) memory traces is indeed indispensable for analyzing mernory causation. (shrink)

The hard problem of consciousness is to explain why certain physical states are conscious: why do they feel the way they do, rather than some other way or no way at all? Arthur Reber claims to solve the hard problem. But he does not: even if we grant that amoebae are conscious, we can ask why such organisms feel the way they do, and Reber’s theory provides no answer. Still, Reber’s theory may be methodologically useful: we do not yet have (...) a satisfactory theory of consciousness, but perhaps the study of simple minds is a way to go about finding one.

Most scholars who presently deal with the Mind-Body problem consider themselves monist materialists. Nevertheless, many of them also assume that there exist (in some sense of existence) mental entities. But since these two positions do not harmonize quite well, the literature is full of discussions about how to reconcile the positions. In this paper, I will defend a materialist theory that avoids all these problems by completely rejecting the existence of mental entities. This is Quine's repudiation theory. According to the (...) theory, there are no mental entities, and the behavioral or physiological phenomena that have been attributed to mental entities, or that point to the existence of these entities, are exclusively caused by physiological factors. To be sure, several objections have been raised to materialist theories that do not assign some role to mental entities. But we will see that Quine is able to give convincing replies to these objections. (shrink)

One of the least explored areas of C.S. Peirce's wide range of work is his contributions to psychology and the philosophy of mind. This dissertation examines the corpus of this work, especially as it relates to the subjects of mind, habit, instinct, sentiment, emotion, perception, consciousness, cognition, and community. The argument is that Peirce's contributions to these areas of investigation were both highly original and heavily influenced by the main intellectual currents of his time. An effort has been made to (...) present Peirce's philosophy without apology, within the conceptual framework and idiom of its time, and without appeal to a comprehensive view that Peirce never articulated. Nevertheless, as several noted interpreters have argued, much of this work can be viewed through the lens of Peirce's innovative theory of signs and the notion of the semiotic triad as its central unifying feature, despite the fact that the general theory was itself under continuous refinement and remained incomplete at the time of his death. Another hermeneutical device employed is William James' better known and more accessible work which, when juxtaposed with Peirce's ideas, serves to bring them into sharper relief. While general and historical in the presentation of material, this study seeks, at the same time, to engage the criticism of contemporary Peirce scholars in an attempt to account for several of the conundrums inherent in Peirce's work. Among the problems with implications for his philosophy of mind and theory of inquiry are the limitations of his theory of continuity, his negative view of the self, his somewhat ambiguous position on the relation of psychology to logic, and the metaethical puzzle arising from application of his theory of probable inference to truly fateful decisions. These problems provide an interesting perspective and lend balance to the truly insightful contributions Peirce made to the discovery of the mind. (shrink)

In everyday life we take it for granted that we have conscious control of some of our actions and that the part of us that exercises control is the conscious mind. Psychosomatic medicine also assumes that the conscious mind can affect body states, and this is supported by evidence that the use of imagery, hypnosis, biofeedback and other ‘mental interventions’ can be therapeutic in a variety of medical conditions. However, there is no accepted theory of mind/body interaction and this has (...) had a detrimental effect on the acceptance of mental causation in science, philosophy and in many areas of clinical practice. Biomedical accounts typically translate the effects of mind into the effects of brain functioning, for example, explaining mind/body interactions in terms of the interconnections and reciprocal control of cortical, neuroendocrine, autonomic and immune systems. While such accounts are instructive, they are implicitly reductionist, and beg the question of how conscious experiences could have bodily effects. On the other hand, non-reductionist accounts have to cope with three problems: 1) The physical world appears causally closed, which would seem to leave no room for conscious intervention. 2) One is not conscious of one’s own brain/body processing, so how could there be conscious control of such processing? 3) Conscious experiences appear to come too late to causally affect the processes to which they most obviously relate. This paper suggests a way of understanding mental causation that resolves these problems. It also suggests that “conscious mental control” needs to be partly understood in terms of the voluntary operations of the preconscious mind, and that this allows an account of biological determinism that is compatible with experienced free will.

There is no doubt that social interaction plays an important role in language-learning, as well as in concept acquisition. In surprising contrast, social interaction makes only passing appearance in our most promising naturalistic theories of content. This is particularly true in the case of mental content (e.g., Cummins, 1996; Dretske, 1981, 1988; Fodor, 1987, 1990a; Millikan, 1984); and insofar as linguistic content derives from mental content (Grice, 1957), social interaction seems missing from our best naturalistic theories of both.1 In this (...) paper, I explore the ways in which even the most individualistic of theories of mental content can, and should, accommodate social effects. I focus especially on the way in which inferential relations, including those that are socially taught, influence language-learning and concept acquisition. I argue that these factors affect the way subjects conceive of mental and linguistic content. Such effects have a dark side: the social and inferential processes in question give rise to misleading intuitions about content itself. They create the illusion that content and inferential relations are more deeply intertwined than they actually are. This illusion confounds an otherwise attractive solution to what is known as ‘Frege’s puzzle’ (Salmon, 1986). I.. (shrink)

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

The aim of this dissertation is to show that, if one is committed to the scientific worldview, one is thereby committed to ethical non-naturalism. In the first chapter I offer the reader an outline of the three primary domains of ethical inquiry: normative ethics, applied ethics, and meta-ethics. I commit myself to a meta-ethical thesis--ethical non-naturalism--and contrast ethical non-naturalism with its competitors. In the second chapter I offer a cursory defense of the moral realist's semantic thesis. I offer reason to (...) think the realist has the correct semantic account and argue against the semantic accounts offered by the realist's primary opponents. In the third chapter of the dissertation I argue that commitment to the scientific worldview requires that one think that the methods of the sciences provide privileged access to facts about the external world and I offer a brief sketch of inference to the best explanation--the primary method I will employ in offering a defense of ethical non-naturalism. In the fourth chapter I develop a method for identifying non-natural properties. The method relies heavily on the predictive power that can be gained by the accurate application of predicates. In the fifth chapter I apply the method developed in the previous chapter. The results are mixed. The method fails to demonstrate that there are non-natural moral facts; however, it does demonstrate that there are non-natural normative facts. Using this result as a lemma, I identify a hypothesis--"[H]"--that, if true, would vindicate ethical non-naturalism. In the sixth chapter I rely on [H] to respond to evolutionary criticisms of ethical non-naturalism and argue that, if morality evolved, we have good reason to believe [H]. In the final chapter, I defend the view I have developed from objections arising from the existence of moral disagreement and I argue that [H] provides the best explanation of the existence of actual moral disagreement.

Functionalism is widely regarded as the central doctrine in the philosophy of cognitive science, and is invoked by philosophers of cognitive science to settle disputes over methodology and other puzzles. I describe a recent dispute over extended cognition in which many commentators appeal to functionalism. I then raise an objection to functionalism as it figures in this dispute, targeting the assumption that generality and abstraction are tightly correlated. Finally, I argue that the new mechanist framework offers more realistic resources for (...) understanding cognitive science, and hence is a better source of appeal for resolving disagreement in philosophy of science.

O presente trabalho efetua um exame do problema mente-corpo por meio do seu rastreamento no campo da Psicologia e, em especial, na Filosofia da Mente contemporânea. O trabalho mostra que o problema mente-corpo é determinado pela forma como uma dada teoria concebe a noção de qualidade e que as abordagens dualistas da mente tratam desta noção em termos de propriedades intrínsecas, ao passo que os materialistas adotam uma teoria da propriedade extrínseca. São exploradas as características das duas abordagens, bem como (...) suas implicações para o problema da possibilidade de um tratamento científico dos processos mentais conscientes.The mind-body problem is examined, taking into consideration its recentpsychological history, especially its contemporary discussions in the Philosophy of Mind. It is argued that the mind-body problem is determined by the way that the notion of quality is theoretically conceived, and that the dualistic approaches of the mind conceive of this notion in terms of intrinsic properties, whereas the materialist approaches embrace an extrinsic properties theory. The dualist and materialist approaches are characterized, as well as their implications to the problem of the possibility of scientific treatment of conscious mental processes. (shrink)

Mental causation is a predominantly theoretical topic rather than a topic studied in the laboratory. The purpose of this paper is to outline a general approach for studying mental causation by empirical means for philosophers and scientists interested in the topic. The aim is to outline how we can infer mental causation by empirical methods given an unknown solution to the mind-body problem. The approach is based on the principles of causal inference to find causal relations among observed variables used (...) in all branches of science. With these principles, it is possible to estimate the causal effects of mental events: Make an experimental manipulation of a mental event, control confounding variables, and estimate causal effects on the outcome. The caveat is that we cannot separate the causal effects of a mental event from the physical base of the mental event, independent of whether we assume mental events can be reduced to their physical base. A challenge to estimating causal effects of mental events is that measured physical variables, such as electrophysiological potentials from the brain, might reflect processes that are part of “higher-order” phenomena, such as mental events. This means that controlling “downwards” for confounding variables is challenging. It is, however, not impossible. It also means that inferring non-mental causes of action cannot be done by measuring only physical variables alone. Keeping the mind-body problem in mind when designing experiments, it is possible to infer mental causation. (shrink)

For the greater part of the last 50 years, it has been common for philosophers of mind and cognitive scientists to invoke the notion of realization in discussing the relationship between the mind and the brain. In traditional philosophy of mind, mental states are said to be realized, instantiated, or implemented in brain states. Artificial intelligence is sometimes described as the attempt either to model or to actually construct systems that realize some of the same psychological abilities that we and (...) other living creatures possess. The claim that specific psychological. (shrink)

Brain-centered theories of consciousness seem to face insuperable difficulties. While some philosophers now doubt that the hard problem of consciousness will ever be solved, others call for radically new approaches to conscious experience. In this article I resurrect a largely forgotten approach to consciousness known as neorealism. According to neorealism, consciousness is merely a part, or cross-section, of the environment. Neorealism implies that all conscious experiences, veridical or otherwise, exist outside of the brain and are wholly independent of being perceived (...) or not; nonveridical perceptions of the environment over an arbitrarily short period of time are supposed to be objective constituents of the environment over a more extended time scale. I argue here that neorealism fares at least as well as brain-centered theories of consciousness on a number of fundamental issues. On one fundamental issue—the nature of the relation between veridical and nonveridical perceptions—neorealism outperforms its competitors. (shrink)

Physicalists are committed to the determination without remainder of the psychological by the physical, but are they committed to this determination being a priori? This paper distinguishes this question understood de dicto from this question understood de re, argues that understood de re the answer is yes in a way that leaves open the answer to the question understood de dicto.

The electromagnetic field theory of consciousness proposes that conscious experiences are identical with certain electromagnetic patterns generated by the brain. While the theory has always acknowledged that not all of the electromagnetic patterns generated by brain activity are conscious, until now it has not been able to specify what might distinguish conscious patterns from non-conscious patterns. Here a hypothesis is proposed about the 3D shape of electromagnetic fields that are conscious, as opposed to those that are not conscious. Seven predictions (...) arising from this hypothesis are described. Existing empirical evidence shows that four of these predictions have already been successfully tested. Requirements for experimental testing of the other three are discussed. (shrink)

John Heil’s From an Ontological Point of View (Heil 2003) is a tremendous philosophical work. The neo-Lockean ontology the reader finds within its 267 pages is a sensible and refreshing alternative to the neo-Humean ontologies which presently occupy the vast majority of the metaphysical literature. What Heil offers is a much needed change in perspective. Nor are the strengths of the book limited to Heil’s willingness to approach central metaphysical problems in largely untried and unpopular way; the book is very (...) clear in its presentation, accessible to wide readership, and tightly argued throughout. Heil’s efforts in this book are to be applauded, and the result is one that warrants serious consideration by all those interested in serious metaphysics. But the interest should not end there: the lessons of Heil’s book are ones that almost all philosophers ought to take seriously. Despite the criticism that follows, my overall position should not be taken as anything short of a whole-hearted endorsement of Heil’s book. Nonetheless, when philosophy is one’s trade, there is always going to be something to disagree about, however much one is amenable to a view. (shrink)
