The argument from causal closure of the physical is usually considered the most powerful argument in favor of the ontological doctrine of physicalism. Many authors, most notably Papineau, assume that CCP implies that physicalism is supported by physics. I demonstrate, however, that physical science has no bias in the ontological debate between proponents of physicalism and dualism. I show that the arguments offered for CCP are effective only against the accounts of mental causation based on the action of the mental (...) forces of a Newtonian nature, i.e. those which manifest themselves by causing accelerations. However, it is conceivable and possible that mental causation is manifested through the redistribution of energy, momentum and other conserved quantities in the system, brought about by altering the state probability distribution within the living system and leading to anomalous correlations of neural processes. After arguing that a probabilistic, interactionist model of mental causation is conceivable, which renders the argument from causal closure of the physical ineffective, I point to some basic features that such a model must have in order to be intelligible. At the same time, I indicate the way that conclusive testing of CCP can be done within the theoretical framework of physics. (shrink)

A sourcebook/textbook on the problem of free will and determinism. Contains a history of the free will problem, a taxonomy of current free will positions, the standard argument against free will, the physics, biology, and neuroscience of free will, the most plausible and practical solution of the problem, and reviews of the work of the leading determinist Ted Honderich, the leading libertarian Robert Kane, the well-known compatibilist Daniel Dennett, and the determinism-agnostic Alfred Mele.

Karl Popper is famous for having proposed that science advances by a process of conjecture and refutation. He is also famous for defending the open society against what he saw as its arch enemies – Plato and Marx. Popper’s contributions to thought are of profound importance, but they are not the last word on the subject. They need to be improved. My concern in this book is to spell out what is of greatest importance in Popper’s work, what its failings (...) are, how it needs to be improved to overcome these failings, and what implications emerge as a result. The book consists of a collection of essays which dramatically develop Karl Popper’s views about natural and social science, and how we should go about trying to solve social problems. Criticism of Popper’s falsificationist philosophy of natural science leads to a conception of science that I call aim-oriented empiricism. This makes explicit metaphysical theses concerning the comprehensibility and knowability of the universe that are an implicit part of scientific knowledge – implicit in the way science excludes all theories that are not explanatory, even those that are more successful empirically than accepted theories. Aim-oriented empiricism has major implications, not just for the academic discipline of philosophy of science, but for science itself. Popper generalized his philosophy of science of falsificationism to arrive at a new conception of rationality – critical rationalism – the key methodological idea of Popper’s profound critical exploration of political and social issues in his The Open Society and Its Enemies, and The Poverty of Historicism. This path of Popper, from scientific method to rationality and social and political issues is followed here, but the starting point is aim-oriented empiricism rather than falsificationism. Aim-oriented empiricism is generalized to form a conception of rationality I call aim-oriented rationalism. This has far-reaching implications for political and social issues, for the nature of social inquiry and the humanities, and indeed for academic inquiry as a whole. The strategies for tackling social problems that arise from aim-oriented rationalism improve on Popper’s recommended strategies of piecemeal social engineering and critical rationalism, associated with Popper’s conception of the open society. This book thus sets out to develop Popper’s philosophy in new and fruitful directions. The theme of the book, in short, is to discover what can be learned from scientific progress about how to achieve social progress towards a better world. (shrink)

What ought to be the aims of science? How can science best serve humanity? What would an ideal science be like, a science that is sensitively and humanely responsive to the needs, problems and aspirations of people? How ought the institutional enterprise of science to be related to the rest of society? What ought to be the relationship between science and art, thought and feeling, reason and desire, mind and heart? Should the social sciences model themselves on the natural sciences: (...) or ought they to take a different form if they are to serve the interests of humanity objectively, sensitively and rigorously? Might it be possible to get into human life, into art, education, politics, industry, international affairs, and other domains of human activity, the same kind of progressive success that is found so strikingly, on the intellectual level, within science? These are some of the questions tackled by What’s Wrong With Science? But the book is no abstruse treatise on the philosophy of science. Most of it takes the form of a passionate debate between a Scientist and a Philosopher, a debate that is by turns humorous, ironical, bitter, dramatically explosive. Even as the argument explores the relationship between thought and feeling, reason and desire, the two main protagonists find it necessary to examine their own feelings and motivations. (shrink)

This book is about experiential content: what it is; what kind of account can be given of it. I am concerned with identifying and attacking one main view - I call it the inferentialist proposal. This account is central to the philosophy of mind, epistemology and philosophy of science and perception. I claim, however, that it needs to be recast into something far more subtle and enriched, and I attempt to provide a better alternative in these pages. The inferentialist proposal (...) holds that experiential content is necessarily under¬pinned by sophisticated cognitive influences. My alternative, the continuum theory, holds that these influences are relevant to experience only at certain levels of organisation and that at other levels there are contents which such features do not capture at all. Central to my account is that there are degrees to which cognitive influences affect experiential content; indeed, for the most part, experience is an amalgam of both inferential and non-inferential features. I claim that the inferentialist proposal is fundamentally flawed and deserves replacement, and I argue that my alternative fills the hollow that remains. The book is divided into four sections. In Part I, Chapter 1, I introduce two traditionally rival views of experiential content. In Chapter 2, I develop my continuum alternative. Chapter 3 assesses the relationship between experience and language, while Chapter 4 explores the relationship between beliefs and experience. The overall argument is that it has been a mistake to understand experience simply in inferential or non-inferential terms. In Part II, I examine the structure of mental content. Chapter 5 is concerned with the kinds of experiences which escape the inferentialist analysis. Chapter 6 considers Kant’s metaphysic of experience counterpointed to Lorenz’s reading of his work in the light of evolutionary biology. Chapter 7 treats animal experience in relation to the continuum view I am developing, while Chapter 8 reviews Fodor’s contribution to perceptual psychology. It is argued that the view of experiential content being developed is both consistent with empirical data on informationally local perceptual sub-systems, but also accords well with evolutionary theory and a naturalist interpretation of Kant’s taxonomy. Part III deals with inferentialism in the philosophy of science. In Chapter 9, I assess the theory dependence of observation thesis as it is advanced by Paul Feyerabend. I bring out of his account a subtle confusion concerning the importance of inference in the context of scientific inquiry. Part IV deals with the issue of experience in the philosophy of mind. In Chapter 10, I look at Wilfred Sellars’s attack on sense data theories. Chapter 11 confronts Paul Churchland’s treatment of ‘folk psychology’ while Chapter 12 isolates the issue of experiential qualia and the position of property dualism. I offer a critical review of Thomas Nagel’s work in this chapter and claim that his position can be read in a way which is consistent with the continuum account I am developing. I conclude the book in the usual fashion with a summary of the central claims. (shrink)

One of the leading concerns animating current philosophy of mind is that, no matter how good a scientific account is, it will leave out what its like to be conscious. The challenge has thus been to study or at least explain away that qualitative dimension. Pursuant with that aim, I investigate how philosophy of signs in the Peircean tradition can positively reshape ongoing debates. Specifically, I think the account of iconic or similarity-based reference we find in semiotic theory offers a (...) more promising variant of the phenomenal concept strategy. Philosophers who endorse this strategy think that the difficulties we have fitting conscious qualia into a scientific picture may owe to the peculiar nature of indexical concepts. They point to the fact that, when we try to convey the feel of our experiences, we employ context-dependent gestures and/or utterances that are indexed to perspectives unique to each person. However, according to the theory I defend, there are three ways signs can refer, namely by convention, causal contact, and similarity. Since similarity is not reducible to proximity, I argue that a theory of reference that turns on shared quality can bypass some of the implausible consequences that plague indexical accounts. In the first chapter, I describe the apparatus needed to make sense of this claim. In the second chapter, I present my account of iconic reference. In the third chapter, I justify my reliance on a distinction that is less than real yet more than nominal. In the fourth chapter, I sketch a trinitarian metaphysics well-suited to house the foregoing account of qualia. (shrink)

been recently proposed (Morin, 2003; 2004). The model takes into account most known mechanisms and processes leading to self-awareness, and examines their multiple and complex interactions. Inner speech is postulated to play a key-role in this model, as it establishes important connections between many of its ele- ments. This paper first reviews past and current references to a link between self-awareness and inner speech. It then presents an analysis of the nature of the relation between these two concepts. It is (...) suggested that inner speech can inter- nally reproduce and expand social and physical (ecological) sources of self- awareness. Inner speech can also create a psychological distance between the self and mental events it experiences (thus facilitating self-observation) it can act as a problem-solving device where the self represents the problem and self-information the solution, and can label aspects of one’s inner life that would otherwise be difficult to objectively perceive. Empirical evidence supporting the role of inner speech in self-awareness is also presented. (shrink)

Bioethics has changed considerably over the years, the increasing diversity of topics of bioethical interest having led to specialisation if not fragmentation. In this context the term “neuroethics" emerged, and it soon became clear that it could be understood in two ways. The “ethics of neuroscience” assesses the ethical and philosophical implications of research in neuroscience and of the application of these discoveries, especially as regards enhancement of “normal” human faculties or new challenges to privacy. The “neuroscience of ethics” basically (...) turns the tables on ethics: it is ethical reasoning itself that becomes the object of neuroscience research. This provides a “behind the scenes” glance into moral reasoning, challenging aspects of moral philoso-phy and of the conventional philosophical interpretation of human action and free will. On the more practical side, neuroethics increases the level of awareness of the relatively neglected area of diseases of the brain-mind. (shrink)

The human brain consists of approximately 100 billion electrically active neurones that generate an endogenous electromagnetic field, whose role in neuronal computing has not been fully examined. The source, magnitude and likely influence of the brain's endogenous em field are here considered. An estimate of the strength and magnitude of the brain's em field is gained from theoretical considerations, brain scanning and microelectrode data. An estimate of the likely influence of the brain's em field is gained from theoretical principles and (...) considerations of the experimental effects of external em fields on neurone firing both in vitro and in vivo. Synchronous firing of distributed neurones phase-locks induced em field fluctuations to increase their magnitude and influence. Synchronous firing has previously been demonstrated to correlate with awareness and perception, indicating that perturbations to the brain's em field also correlate with awareness. The brain's em field represents an integrated electromagnetic field representation of distributed neuronal information and has dynamics that closely map to those expected for a correlate of consciousness. I propose that the brain's em information field is the physical substrate of conscious awareness - the cemi field - and make a number of predictions that follow from this proposal. Experimental evidence pertinent to these predictions is examined and shown to be entirely consistent with the cemi field theory. This theory provides solutions to many of the intractable problems of consciousness - such as the binding problem - and provides new insights into the role of consciousness, the meaning of free will and the nature of qualia. It thus places consciousness within a secure physical framework and provides a route towards constructing an artificial consciousness. (shrink)

This paper addresses the question whether evolutionary principles are compatible with epiphenomenalism, and argues for an affirmative answer. A general summary of epiphenomenalism is provided, along with certain specifications relevant to the issues of this paper. The central argument against compatibility is stated and rebutted. A specially powerful version of the argument, due to William James (1890), is stated. The apparent power of this argument is explained as resulting from a problem about our understanding of pleasure and an equivocation on (...) 'explanation'. Finally, an argument by Plantinga (2004), which applies to beliefs rather than phenomenal qualities, is stated and rebutted. (shrink)

There is a tension or even contradiction between mental causation - the belief that some mental events or properties are causally relevant for some physical events or properties - and the irreducibility of mental features to physical ones, the causal closure of the physical, and the assumption that there is no overdetermination of the physical. To reconcile these premises was a promise of nonreductive physicalism, but a closer inspection shows that it is, on the contrary, a source of the problem (...) - namely, the unintelligibility of mental causation. This has to do with the widely-held assumption that the mental supervenes on the physical. How can the mental be causally relevant, then? And what is the relationship of the mental and the physical? There are many options, including identity, realizationism, emergence, or some kind of reducibility. But they all have their own problems, e.g. they threaten mental reality, the causal closure of the physical, or scientific explanations. All these aspects are covered in Jaegwon Kim's book Mind in a Physical World. This paper is a detailed introduction to it, discussing and critically commenting it and those still intriguing, but also confusing and complicated issues of the mind-body problem, especially the ontology of mental causation.

Gender greatly impacts access to opportunities, potential, and success in corporate leadership roles. We begin with a general presentation of why such discussion is necessary for basic considerations of justice and fairness in gender equality and how the issues we raise must impact any ethical perspective on gender in the corporate workplace. We continue with a breakdown of the central categories affecting the success of women in corporate leadership roles. The first of these includes gender-influenced behavioral factors, such as the (...) requirements and expectations of gendered verbal and nonverbal communication styles as well as appearance. We move on to address the impact of family on corporate leadership opportunities and success, discussing the asymmetrical evaluation of an individual’s potential, authority, and competence based on gender stereotypes of familial obligations and expectations. Finally, we address how gender impacts access to networking and sponsorship opportunities and the long-term effects of systematic limitations on women’s inclusion in the upper echelons of corporate leadership. We conclude with a summary of the questions and issues raised by our discussion and direct individuals to consider how different ethical systems and moral requirements might influence their interpretations of gender and leadership in the corporate workplace.

Philosophy of science is seen by most as a meta-discipline – one that takes science as its subject matter, and seeks to acquire knowledge and understanding about science without in any way affecting, or contributing to, science itself. Karl Popper’s approach is very different. His first love is natural philosophy or, as he would put it, cosmology. This intermingles cosmology and the rest of natural science with epistemology, methodology and metaphysics. Paradoxically, however, one of his best known contributions, his proposed (...) solution to the problem of demarcation, helps to maintain the gulf that separates science from metaphysics, thus fragmenting cosmology into falsifiable science on the one hand, untestable philosophy on the other. This has damaging repercussions for a number of issues Popper tackles, from the problem of induction to simplicity of theory and quantum theory. But his proposed solution to the demarcation problem is untenable. Metaphysical assumptions are an integral part of scientific knowledge, inherent in the persistent acceptance of unified theories against the evidence. Once this is appreciated, it becomes obvious that natural philosophy, a synthesis of science and philosophy, is both more rigorous and of greater intellectual value than the two dissociated components we have today. What Popper sought for could come to full fruition. Problems that Popper tackled, from the problem of induction, to the problem of unity of theory, problems of quantum theory, and problems concerning the scope and limits of physics, all receive more adequate resolution within the new, fully-fledged natural philosophy.

Philosophical work on free will, contemporary as well as historical, is inevitably framed by the problem of free will and determinism. One of my goals in what follows is to give a feel for the main lines of that debate in philosophy today. I will also be outlining a particular perspective on free will. Many working philosophers consider themselves Compatibilists; the perspective outlined, building on a number of arguments in the recent literature, is a contemporary form of such a view. (...) It cannot, however, claim to be the contemporary philosophical perspective. There is no such thing. Against a background of the perennial problem of free will and determinism, through ongoing argument and debate, philosophers continue to try to work toward an understanding of precisely what it means for an action to be free.

1. Introduction The readiness potential was found to precede voluntary acts by about half a second or more (Kornhuber & Deecke, 1965). Kornhuber (1984) discussed the readiness potential in terms of volition, arguing that it is not the manifestation of an attentional processes. Libet discussed it in relation to consciousness and to free will (Libet et al. 1983a; 1983b; Libet, 1985, 1992, 1993). Libet asked the following questions. Are voluntary acts initiated by a conscious decision to act? Are the physiological (...) facts compatible with the belief that free will determines our voluntary acts? What is the role of consciousness in voluntary action? In this paper I will discuss these questions and the answers that Libet gave to them. (shrink)

This is a draft for a revised edition of Mark Sharlow's book "From Brain to Cosmos." It includes most of the material from the first edition, two shorter pieces pertaining to the book, and a detailed new introduction.

Natural resources are infinite. This is possible because humans can create theories whose potential goes beyond the limited imaginative capacity of the inventor. For instance, no number of people can work out all the economic potential of quantum theory. Economic Resources are created by an interaction of Karl Popper's Worlds 1, 2 and 3, the worlds of physics, psychology and the abstract products of the human mind, such as scientific theories. Knowledge such as scientific theories has unfathomable information content, is (...) universally applicable, and infinitely copyable. The point can be made with technological knowledge such as that embodied in the wheel. The theory of the wheel has un- bounded potential to be embodied in unforeseeable new technologies, is useful on the Moon as on Earth, and can be infinitely copied. Unlike a piece of land (using fixed factors), such knowledge shows increasing returns. This helps to explain Julian Simon's observation that "natural" resources are now less scarce than they used to be and why an increasing population can increase resources in the long-run. It was Simon's breakthrough to elaborate on the abstract character of "natural" resources. I further explore this abstract character and thereby explain why natural resources are infinitely expandable. Economic growth and the creation of natural resources depends on the rate of invention. F. Machlup's suggestion (Machlup 1962) that the opportunity for new inventions increases geometrically with the number of inventions at hand is acknowledged for its suggestiveness, but criticised for its conservative position. Frank Tipler's fascinating argument for indefinite economic growth (Tipler 1994), is reinforced by my argument by making a distinction between information in the engineer's sense and the infinite potential "information" in our scientific knowledge based on Popper's notion of information content.

The Exclusion Argument for physicalism maintains that since (1) every physical effect has a sufficient physical cause, and (2) cases of causal overdetermination are rare, it follows that if (3) mental events cause physical events as frequently as they seem to, then (4) mental events must be physical in nature. In defence of (1), it is sometimes said that (1) is supported if not entailed by conservation laws. Against this, I argue that conservation laws do not lend sufficient support to (...) (1) to render its denial ‘unscientific’, and that those who accept (3) and deny (4) may consequently respond to the Exclusion Argument by denying (1) without thereby setting themselves at odds with current science. I also argue that conservation laws are compatible with (3) and the negation of (4), and that one can therefore accept conservation laws and (3) while denying both (1) and (4). (shrink)

The existence of neural correlates of consciousness (NCC) is not enough for philosophical purposes. On the other hand, there's more to NCC than meets the sceptic's eye. (I) NCC are useful for a better understanding of conscious experience, for instance: (1) NCC are helpful to explain phenomenological features of consciousness – e.g., dreaming. (2) NCC can account for phenomenological opaque facts – e.g., the temporal structure of consciousness. (3) NCC reveal properties and functions of consciousness which cannot be elucidated either (...) by introspective phenomenology or by psychological experiments alone – e.g., vision. (II) There are crucial problems and shortcomings of NCC: (1) Correlation implies neither causation nor identity. (2) There are limitations of empirical access due to the problem of other minds and the problem of self-deception, and (3) due to the restrictions provided by inter- and intraindividual variations. (4) NCC cannot be catched by neuroscience alone because of the externalistic content of representations. Therefore, NCC are not sufficient for a naturalistic theory of mind, (5) nor are they necessary because of the possibility of multiple realization. (III) Nevertheless, NCC are relevant and important for the mind-body problem: (1) NCC reveal features that are necessary at least for behavioral manifestations of human consciousness. (2) But NCC are compatible with very different proposals for a solution of the mind-body problem. This seems to be both advantageous and detrimental. (3) NCC restrict nomological identity accounts. (4) The investigation of NCC can refute empirical arguments for interactionism as a case study of John Eccles' dualistic proposals will show. (5) The discoveries of NCC cannot establish a naturalistic theory of mind alone, for which, e.g., a principle of supervenience and a further condition – and therefore philosophical arguments – are required.

The conclusion of physics, within both a historical and more recent context, that an objectively progressive time and present moment are derivative notions without actual physical foundation in nature, illustrate that these perceived chronological features originate from subjective conscious experience and the neurobiological processes underlying it. Using this conclusion as a stepping stone, it is posited that the phenomena of an in-built subjective conception of a progressive present moment in time and that of conscious awareness are actually one and the (...) same thing, and as such, are also the outcome of the same neurobiological processes. A possible explanation as to how this might be achieved by the brain through employing the neuronal induced nonconscious cognitive manipulation of a small interval of time is proposed. The CIP phenomenon, elucidated within the context of this study is also then discussed. (shrink)

I here describe meanings attributed to the term consciousness, extracted from the literature and from recent online discussions. Forty such meanings were identified and categorized according to whether they were principally about function or about experience; some overlapped but others were apparently mutually exclusive - and this list is by no means exhaustive. Most can be regarded as expressions of authors' views about the basis of con-sciousness, or opinions about the significance of aspects of its con-tents. The prospects for reaching (...) any single, agreed, theory independent definition of consciousness thus appear remote. How-ever, much confusion could be avoided if authors were always to spec-ify which aspects of consciousness they refer to when using the term. An example is outlined of how this can be done.

In this article a concept of non-local consciousness will be described, based on recent scientific research on near-death experiences . Since the publication of several prospective studies on NDEs in survivors of cardiac arrest, with strikingly similar results and conclusions, the phenomenon of the NDE can no longer be scientifically ignored. In the last thirty years several theories have been proposed to explain an NDE. The challenge to find a common explanation for the cause and content of an NDE is (...) complicated by the fact that an NDE can be experienced during various circumstances, such as severe injury of the brain as in cardiac arrest to conditions when the brain seems to function normally. The NDE is an authentic experience which cannot be simply reduced to imagination, fear of death, hallucination, psychosis, the use of drugs, or oxygen deficiency. Patients appear to be permanently changed by an NDE during a cardiac arrest of only some minutes duration. According to these aforementioned studies, the current materialistic view of the relationship between consciousness and the brain as held by most physicians, philosophers, and psychologists is too restricted for a proper understanding of this phenomenon. There are good reasons to assume that our consciousness does not always coincide with the functioning of our brain: enhanced or non-local consciousness can sometimes be experienced separately from the body.

The existence of quantum correlates of consciousness (QCC) is doubtful from a scientific perspective. But even if their existence were verified, philosophical problems would remain. On the other hand, there could be more to QCC than meets the sceptic's eye: • QCC might be useful or even necessary for a better understanding of conscious experience or quantum physics or both. The main reasons for this are: the measurement problem (the nature of observation, the mysterious collapse of the wave function, etc.), (...) ostensibly shared features of quantum phenomena and conscious phenomena (e.g., complementarity, nonspatiality, acausality, spontaneity, and holism) and connections (ontology, causation, and knowledge), the qualia problem (subjectivity, explanatory gap etc.). But there are many problems, especially questions regarding realism and the nature and role of conscious observers; • QCC are conceptually challenging, because there are definitory problems and some crucial ontological and epistemological shortcomings. It is instructive to compare them with recent proposals for understanding neural correlates of consciousness (NCC). QCC are not sufficient for a quantum theory of mind, nor might they be necessary except perhaps in a very broad sense; • QCC are also empirically challenging. Nevertheless, QCC could be relevant and important for the mindbody problem: QCC might reveal features that are necessary at least for behavioral manifestations of human consciousness. But QCC are compatible with very different proposals for a solution of the mind-body problem. This seems to be both advantageous and detrimental. QCC restrict accounts of nomological identity. The discovery of QCC cannot establish a naturalistic theory of mind alone. But there are also problems with QCC in the framework of other ontologies. (shrink)

The Epiphenomenal Mind is both a deflationary attack on the powers of the human mind and a defence of human subjectivity. It is deflationary because in the thesis I argue that consciousness is an epiphenomenal consequence of events in the brain. It is a defence of human subjectivity because I argue that the mind is sui generis real, irreducible, and largely an endogenous product (i.e. not dependent on society or its resources). Part I is devoted to arguing that the conscious (...) mind is epiphenomenal. Arguing from, the irreducibility of mental states, the causal closure of the physical domain, and the principle of causal explanatory exclusion, I seek to demonstrate that all theories of mental causation necessarily violate one or more of these premises. Contemporary approaches to mental causation come under two broad categories, those that argue that mental events are supervenient on physical events (such as Davidson, Kim and Horgan) and those (like Haskar) who argue that the mind is an emergent property of the brain. Supervenience based theories, I argue, end up reducing mental states in their search for a theory of mental causation and emergence based theories end up violating the principle of the causal closure of the physical. In part II, I explore some of the consequences of epiphenomenalism for social theory. This exploration comes in the context of a defence of human subjectivity against (i.) those sociological imperialists who view the mind and self as a 'gift of society', and (ii.) social situationalists who have abandoned the concept of action and an interest in 'what's in the head' of the actor, in favour of a concept of social action which views behaviour as action only to the extent that it is socially meaningful. The conclusion is that the social sciences should return to an interpretative style (Weberian) methodology. (shrink)

Mainstream research on reading and writing is based on the assumption, common in modern linguistics, that spoken language is primary to written language in most important respects. Unfortunately, the conceptual framework for the study of language and 'literacy' is built around this assumption. This is problematic with regard to the philosophy of science, since this framework lacks sufficient empirical support. It is claimed in the present thesis that a view of spoken and written language as distinct - but not isolated (...) - sets of codes with potential for meaning is the best working hypothesis in the search for true empirical findings about the relationship between spoken- and written-language skills. This position calls for critical reflection on the conceptual framework used in research on reading and writing. Article I examines the notion of 'phonology' in dyslexia research, particularly within the paradigm of cognitive psychology. Focusing on the problem of vague and non-falsifiable hypotheses involving phonology, it calls for a more 'vulnerable' theory. Article II discusses the status of the concept of 'phoneme' in psycholinguistics with regard to the purposes of understanding, explanation and description in science. It is argued that the phoneme relates primarily to the domain of description and that its adequacy for explanation of written-language skills is marginal. Article III discusses the role of the concept of 'frequency' versus phonological descriptions in the study of written-language acquisition, and a model for maintaining dynamic perspectives on acquisition is suggested. Article IV investigates a widespread definition of 'reading' in cognitive psychology, suggesting an alternative definition. Article V examines the notion of 'lexicon' in research on written-language skills. An alternative conception of 'lexicon' is proposed within the context of connectionism and functional linguistics. Article VI focuses on sensitivity to prosody and the doubling of consonants in writing. A nuanced model of 'skill' is applied to enable sensivity to quantity to be captured according to commonly accepted standards of empirical science. Article VII suggests an alternative model of writing with a special focus on how to conceive of the relationship between end-product and on-line measures. (shrink)

In this article I look at some the issues, problems and self-imposed dilemmas that emerge from Harry Frankfurt’s well-known essay ‘Freedom of the Will and the Concept of a Person’. That essay has exerted a widespread influence on subsequent thinking in ethics and philosophy of mind, especially through its central idea of ‘second-order’ desires and volitions. Frankfurt’s approach promises a third-way solution to certain longstanding issues – chiefly those of free-will versus determinism and the mind/body problem – that have up (...) to now resisted the best efforts of philosophical deliverance or therapy. It looks very much like the kind of answer that would avoid the ‘high priori road’ of any Kantian or suchlike metaphysical approach by adopting a broadly naturalized conception of human moral agency while not going so far down the path toward wholesale ethical naturalism as to lose the benefits that come with the Kantian conception. However I suggest that this appearance is deceptive and that Frankfurt’s way of addressing these issues – especially his leading idea of second-order desires and volitions – lies open to a long-familiar range of objections from both a naturalist and a strong autonomist quarter. More specifically, I show that his notion of moral will as possessing a multiplex structure whereby higher-order volitions can reject or countermand the promptings of unregenerate first-order desire is one that must inherently give rise to various problems of a logical, metaphysical, and – most importantly in this context – ethical character. I conclude that a thoroughgoing naturalism is the only response that can meet the kinds of challenge increasingly mounted from various scientific quarters, notably those of neurophysiology and cognitive psychology.U ovome članku razmatram neka pitanja, probleme i, kako mi se čini, samonametnute dileme koje proizlaze iz dobro poznatog ogleda Harryja Frankfurta “Freedom of the Will and the Concept of a Person”. Taj je ogled izvršio široki utjecaj na kasnije mišljenje u etici i filozofiji uma, naročito svojom središnjom idejom želja i htijenja “drugog reda”. Frankfurtov pristup obećava rješenje u obliku trećeg puta određenih starih problema – uglavnom problema odnosa slobodne volje i determinizma te odnosa uma i tijela – koji su se dosad opirali najboljim naporima filozofskog rješavanja ili terapije. On veoma nalikuje onoj vrsti odgovora koji apriorni put bilo kakva kantovskog ili sličnog metafizičkog pristupa želi izbjeći usvajanjem u širokom smislu naturalizirane koncepcije ljudskog moralnog djelovanja, ali tako da ne ode toliko daleko u smjeru etičkog naturalizma da izgubi prednosti koje su povezane s kantovskim pristupom. Tvrdim, međutim, da takav izgled vara i da je Frankfurtov način pristupanja tim pitanjima – a naročito njegova glavna ideja želja i htijenja drugog reda – podložna odavno poznatim prigovorima koji dolaze kako od strane naturalistâ tako i od strane strogih autonomista . Konkretnije, pokazujem da njegov pojam moralne volje kao nečega što posjeduje kompleksnu strukturu, čime htijenja višeg reda mogu odbaciti ili poništiti poticaje pokvarene želje prvog reda, jest takav da inherentno mora izazvati različite logičke, metafizičke i – što je u ovome kontekstu najvažnije – etičke probleme. Zaključujem da je posvemašnji naturalizam jedini odgovor koji može izaći na kraj s izazovima koji se sve više upućuju iz različitih znanstvenih krugova, naročito iz područja neurofiziologije i kognitivne psihologije.

Considerando que para os fins deste texto os termos “eu” e “sujeito” sáo usados como sinônimos, o título do presente artigo poderia (...) ser: “O que o sujeito pensa que está fazendo no cosmos?”; “O ‘eu’ pensa que por ser autocriado é Deus?”; “Pode objetivamente uma máquina ser insubstituível?” Ou ainda: “O fantasma emerge no mundo”; Todas essas possibilidades têm em comum a indicaçáo direta ou metafórica da interdependência entre o “eu” (o sujeito, o fantasma, a personalidade), o cérebro (máquina, corpo) e o pensamento objetivo (resultado da interaçáo entre o “eu” e o cérebro). Qualquer das possibilidades acima evita as variáveis à pergunta que tradicionalmente foi feita: o que é o “eu”? Este tipo de questáo normalmente conduz a respostas essencialistas, infrutíferas e que redundam em verbalismos e equívocos. (shrink)

We may suspect that quantum mechanics and consciousness are related, but the details are not at all clear. In this paper, I suggest how the mind and brain might fit together intimately while still maintaining distinct identities. The connection is based on the correspondence of similar functions in both the mind and the quantum-mechanical brain. Accompanying material for a talk at The Second Mind and Brain Symposium held at the Institute of Psychiatry, Denmark Hill, London on 20th October, 1990.

Unlike almost all other philosophers of science, Karl Popper sought to contribute to natural philosophy or cosmology – a synthesis of science and philosophy. I consider his contributions to the philosophy of science and quantum theory in this light. There is, however, a paradox. Popper’s most famous contribution – his principle of demarcation – in driving a wedge between science and metaphysics, serves to undermine the very thing he professes to love: natural philosophy. I argue that Popper’s philosophy of science (...) is, in this respect, defective. Science cannot proceed without making highly problematic metaphysical assumptions concerning the comprehensibility and knowability of the universe. Precisely because these assumptions are problematic, rigour requires that they be subjected to sustained critical scrutiny, as an integral part of science itself. Popper’s principle of demarcation must be rejected. Metaphysics and philosophy of science become a vital part of science. Natural philosophy is reborn. A solution to the problem of what it means to say a theory is unified is proposed, a problem Popper failed to solve. In The Logic of Scientific Discovery, Popper made important contributions to the interpretation of quantum theory, especially in connection with Heisenberg's uncertainty relations. Popper's advocacy of natural philosophy has important implications for education. (shrink)

In this paper a new interactionistic model of mental causation is developed. By analysing the results of physics and neuroscience it is shown that the macroscopic cerebral activity and the resulting behavioural output is not strictly determined. This opens up the possibility that a non-physical mind can influence which of the physically allowed brain states is realised. Most models of mental causation postulate that there are coherent quantum states in the brain which could be influenced by a local mind-brain interaction. (...) Due to environmental decoherence, however, it is questionable whether coherent quantum states can exist in the warm and wet brain. The here presented `creative choice theory' solves the problem of environmental decoherence by including the environment. The whole universe is considered as a quantum system that is in superposition of alternative realities. It is then assumed that a universal mind collapses the universal wave-function whilst individual minds interact with individual brains. This leads to a holistic model of reality that could also provide an explanation for ESP-phenomena and mystical experiences. (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 principles of classical physics, including deterministic dynamics and observability of physical states, are incompatible with the existence of unobservable conscious minds that possess free will. Attempts to directly accommodate consciousness in a classical world lead to philosophical paradoxes such as causally ineffective consciousness and possibility of alternate worlds in which functional brain isomorphs behave identically but lack conscious experiences. Here, we show that because Chalmers’ principle of organizational invariance is based on a deficient nineteenth century classical physics, it is (...) inherently flawed and implies evolutionary inexplicable epiphenomenal consciousness. Consequently, if consciousness is a fundamental ingredient of physical reality, no psychophysical laws such as Chalmers’ principle of organizational invariance are needed to establish correspondence between conscious experiences and brain function. Quantum mechanics is the most successful and only modern physical theory capable of naturally accommodating consciousness without violation of physical laws. (shrink)

Little is known with regard to the precise cognitive tools the self uses in acquiring and processing information about itself. In this article, we underline the possibility that inner speech might just represent one such cognitive process. Duval and Wicklund’s theory of self-awareness and the selfconsciousness, and self-knowledge body of work that was inspired by it are reviewed, and the suggestion is put forward that inner speech parallels the state of self-awareness, is more frequently used among highly self-conscious persons, and (...) represents an effective, if not indispensable, tool involved in the formation of the self-concept. The possibility is also raised that the extent to which one uses inner speech could partially explain individual differences in self-consciousness and self-knowledge. A selective review of the private and inner speech literature is presented, and some possible ways of testing the hypothesis by using pre-existing techniques are proposed in the hope of stimulating empirical investigations. Some implications are outlined in conclusion. (shrink)

This paper, Part III of a critique of survivalist interpretations of near-death experiences (NDEs), considers psychophysiological and cultural correlates of NDEs suggesting that such experiences are solely products of individuals' minds rather than windows into a transcendental realm. While current psychophysiological models do not fully explain out-of-body experiences (OBEs) and NDEs, several psychophysiological correlates offer promising clues about the mechanisms implicated in their production. These correlates do not definitively identify their precise causes, but strongly imply that such experiences represent internally (...) generated fantasies rather than genuine perceptions of a transcendental environment. Additionally, stark differences in the phenomenology of NDEs from different cultures have been uncovered. Though nonWestern samples are too limited to draw anything more than tentative conclusions, the available data suggest that prototypical Western NDE motifs derive from a cultural source, consistent with the hypothesis that NDE content reflects social conditioning and personal expectation rather than the perception of an external reality.
