There has in recent years been a significant surge of interest in non-materialist accounts of the mind. Property dualists hold that all substances (concrete particulars that persist over time) are material, but mental properties are distinct from physical properties. Substance dualists maintain that the mind or person is a non-material substance. This article considers the prospects for substance dualism given the current state of the debate. The best known type of substance dualism, Cartesian dualism, has traditionally faced a number of (...) objections, but many contemporary philosophers have sought to avoid these by formulating novel versions of the view. I identify three central claims held in common by all forms of substance dualism, consider recent arguments for these claims, and assess how successfully different types of substance dualism respond to the traditional objections. I argue that most contemporary forms of the view still face one or more of three major challenges, from bundle theories of the self, from the recently developed “phenomenal concepts strategy”, and from worries about explanatory simplicity.

A set of hypotheses is formulated for a connectionist approach to cognitive modeling. These hypotheses are shown to be incompatible with the hypotheses underlying traditional cognitive models. The connectionist models considered are massively parallel numerical computational systems that are a kind of continuous dynamical system. The numerical variables in the system correspond semantically to fine-grained features below the level of the concepts consciously used to describe the task domain. The level of analysis is intermediate between those of symbolic cognitive models (...) and neural models. The explanations of behavior provided are like those traditional in the physical sciences, unlike the explanations provided by symbolic models. (shrink)

In Gray's conjecture, mismatches in the subicular comparator and matches have equal prominence in consciousness. In rival cognitive views novelty and difficulty especially elicit more conscious modes of cognition and higher levels of self-regulation. The mismatch between Gray's conjecture and these views is discussed.

Do theories of quantum mechanics and quantum gravity require spacetime to be a basic, ground level feature, or can spacetime be seen as an emergent element of these theories? While several commentators have raised serious doubts about the prospects of forgoing the standard spacetime backdrop, it will be argued that a defense of these emergent spacetime interpretations of quantum mechanics and quantum gravity hypotheses can be made, whether as an inference to the best explanation or using another strategy. Furthermore, the (...) idea that space and time can arise from a quite different, non-spatiotemporal level of reality will be shown to have various historical precedents, especially in the seventeenth and eighteenth centuries, a realization that may help dispel some of the mystery associated with these types of hypotheses.

The moot point of the Western philosophical rhetoric about free will consists in examining whether the claim of authorship to intentional, deliberative actions fits into or is undermined by a one-way causal framework of determinism. Philosophers who think that reconciliation between the two is possible are known as metaphysical compatibilists. However, there are philosophers populating the other end of the spectrum, known as the metaphysical libertarians, who maintain that claim to intentional agency cannot be sustained unless it is assumed that (...) indeterministic causal processes pervade the action-implementation apparatus employed by the agent. The metaphysical libertarians differ among themselves on the question of whether the indeterministic causal relation exists between the series of intentional states and processes, both conscious and unconscious, and the action, making claim for what has come to be known as the event-causal view, or between the agent and the action, arguing that a sort of agent causation is at work. In this paper, I have tried to propose that certain features of both event-causal and agent-causal libertarian views need to be combined in order to provide a more defendable compatibilist account accommodating deliberative actions with deterministic causation. The ‘‘agent-executed-eventcausal libertarianism’’, the account of agency I have tried to develop here, integrates certain plausible features of the two competing accounts of libertarianism turning them into a consistent whole. I hope to show in the process that the integration of these two variants of libertarianism does not challenge what some accounts of metaphysical compatibilism propose—that there exists a broader deterministic relation between the web of mental and extra-mental components constituting the agent’s dispositional system—the agent’s beliefs, desires, short-term and long-term goals based on them, the acquired social, cultural and religious beliefs, the general and immediate and situational environment in which the agent is placed, etc. on the one hand and the decisions she makes over her lifetime on the basis of these factors. While in the ‘‘Introduction’’ the philosophically assumed anomaly between deterministic causation and the intentional act of deciding has been briefly surveyed, the second section is devoted to the task of bridging the gap between compatibilism and libertarianism. The next section of the paper turns to an analysis of folk-psychological concepts and intuitions about the effects of neurochemical processes and prior mental events on the freedom of making choices. How philosophical insights can be beneficially informed by taking into consideration folk-psychological intuitions has also been discussed, thus setting up the background for such analysis. It has been suggested in the end that support for the proposed theory of intentional agency can be found in the folk-psychological intuitions, when they are taken in the right perspective. (shrink)

The mind-body relationship has vexed philosophers of mind for quite a long time. Different theories of mind have offered different points of view about the interaction between the two, but none of them seem free of ambiguities and questions. This paper attempts to use a mathematical model for mind-body relationship. The model may generate some questions to think about this relationship from the viewpoint of operator theory.

Abstract I aim to examine two questions. First, whether ‘folk psychology’ is a kind of theory and, second, more seriously, how are we to understand the system of principles of folk psychology. As to the first, there is a confusion between ‘theory’ and ‘science’. Much of the debate ignores the differences between these, and I argue that whereas folk psychology cannot be called a science there are grounds for calling it a theory. On the more serious question of interpretation, I (...) review the general considerations against instrumentalism and argue that they do not apply to folk psychology. The instrumentalist construal of folk psychology is strengthened by the remarkable fact that folk psychology is guaranteed to be successfully applicable to almost any system that has evolved under natural selection. Thus one can maintain that folk psychology is in fact a codification of certain quite general principles of evolutionary theory, and thus is an ancient and brilliant instrument for explaining the behaviour of complex evolved systems. It is, however, an instrument whose ‘theoretical posits’ may have very little to do with the actual springs of action which operate at the level of the neuron or assemblies of neurons. (shrink)

This paper examines the nature of theory structure in biology and considers the implications of those theoretical structures for theory reduction. An account of biological theories as interlevel prototypes embodying causal sequences, and related to each other by strong analogies, is presented, and examples from the neurosciences are provided to illustrate these middle-range theories. I then go on to discuss several modifications of Nagel''s classical model of theory reduction, and indicate at what stages in the development of reductions these models (...) might best apply. Finally I consider several implications of these analyses of theory structure and reduction for disciplinary integration in biology. (shrink)

Summary Searle claims that for a machine to have intentional states it is not sufficient that a formal programme be instantiated. Various types of objections to this claim have been brought up by Searle's critics. Searle's replies to some of these objections are analysed. It turns out that it is more to these objections than Searle wants to make us believe. What is crucial, however, is that Searle's „Gedankenexperiment results in a dilemma. At the outset of the dilemma there are (...) two ways of not understanding. According to one of these ways a person (Searle's homunculus) does not understand something without knowing that s/he does not understand. While in the other mode the person knows that s/he doesn't understand. In the first case the inference from facts about the homunculus to facts about the computer is not valid whereas in the second case one would attribute mental states to the computer. Thereby Searle's claim turns out to be unfounded. (shrink)

If you’re a materialist, you probably think that rabbits are conscious. And you ought to think that. After all, rabbits are a lot like us, biologically and neurophysiologically. If you’re a materialist, you probably also think that conscious experience would be present in a wide range of naturally-evolved alien beings behaviorally very similar to us even if they are physiologically very different. And you ought to think that. After all, to deny it seems insupportable Earthly chauvinism. But a materialist who (...) accepts consciousness in weirdly formed aliens ought also to accept consciousness in spatially distributed group entities. If she then also accepts rabbit consciousness, she ought to accept the possibility of consciousness even in rather dumb group entities. Finally, the United States would seem to be a rather dumb group entity of the relevant sort. If we set aside our morphological prejudices against spatially distributed group entities, we can see that the United States has all the types of properties that materialists tend to regard as characteristic of conscious beings.

The communicative aspects of the contents of consciousness are analyzed in the framework of a neural network model of animal communication. We discuss some issues raised by Gray, such as the control of the contents of consciousness, the adaptive value of consciousness, conscious and unconscious behaviors, and the nature of a model's consciousness.

In a brief overview this article discusses that, in the multifaceted field of cognitive sciences, the problem of consciousness and mind is far from being resolved. The article then argues that this problem is worked out in careful detail in Peirce’s work. Intelligence, hence mind, for Peirce, is distinct from consciousness. Without being dissociable, they are, in fact, distinct but complementary. Hence, Peirce’s ideas should be recovered not only for the sake of their relevance, but also because cognitivists have a (...) lot to learn from Peirce. (shrink)

I address some specific problems in the two target articles offered here (Rao and Palmer/Alcock: Parapsychology review and critique), which are indicative of more general problems that plague the larger debate. Because such problems are rather typical of scientific conflict, I address general problems of assessment in a second section. In a final section. I make some comments about the future of this debate.

Ziel des Aufsatzes ist es, einige relevante Sachverhalte aus der Philosophie Descartes' hervorzuheben, welche die Entwicklung der Leib-Seele-Problem-Debatte maßgeblich geprägt haben. Aus der Sicht gegenwärtiger philosophischer Debatte wird die Fundierung des ontologischen Dualismus Descartes' aufgewiesen, um schließlich diesen Standpunkt einer kritischen Würdigung zu unterziehen—mit dem Blick auf eine Zukunftsperspektive. Das methodische Verfahren nimmt Rücksicht sowohl auf den Bereich a priori als auch den a posteriori.

I distinguish between being cognisant and being able to perform intelligent operations. The former, but not the latter, minimally involves the capacity to make adequate judgements about one's relation to objects in the environment. The referential nature of cognisance entails that the mental states of cognisant systems must be inter-related holistically, such that an individual thought becomes possible because of its relation to a system of potential thoughts. I use Gareth Evans' 'Generality Constraint' as a means of describing how the (...) reference and holism of mental states in cognisant systems are mutually dependent. Next, I describe attempts to deny the relevance of holism and reference by positing a mentalese. These attempts fail because the meanings of symbols are under determined, with there being no principled means of distinguishing between the mental tokening of a symbol and its disambiguation. I argue that the connectionist meta-theory does not encounter this problem because it is able to encompass the holism of the mental. Recent attempts to show that symbol processing theories of thought must be preferred to connectionist theories do not work. Despite appearances to the contrary, the Generality Constraint favours connectionist not symbol-processing theories. (shrink)

This paper sketches an alternative answer to James Jones's recent attempt to explore the implications of cognitive social learning theories of personality for issues in epistemology, philosophy of science, and religious studies. Since the 1960s, two cognitive revolutions have taken place in scientific psychology: the first made cognition central to theories of perception, memory, problem solving, and so on; the second made cognition central to theories of learning and behavior, among others. Cognitive social learning theories find their place in the (...) latter revolution. Because of an ongoing naturalistic revolution in philosophy, these cognitive revolutions in psychology are having a profound effect on both descriptive and normative issues in epistemology and philosophy of science. From the naturalistic perspective, philosophy cannot adequately pursue its goals without the contributions of the empirical sciences, including psychology. The author concludes that the cognitive revolutions in psychology and the naturalistic revolution in philosophy have similar descriptive and normative import for the study of religion. (shrink)

Los diversos estudios que circundan en la literatura de la filosofía de la mente nos acercan a la comprensión de la conciencia desde estudios fisicalistas, naturalistas, y eliminativistas, los cuales, en su mayoría, terminan por sucumbir en el problema del dualismo. La teoría del emergentismo searleano realiza su aporte sobre la comprensión de la naturaleza de la conciencia desde la contribución de las neurociencias, sin caer en reduccionismos y presenta una alternativa de superación del dualismo. Pese a ello, al analizar (...) la teoría naturalista de Searle se evidencia que esta resulta ser insuficiente para comprender la naturaleza del fenómeno mental, además de caer en un nuevo dualismo: naturaleza/sociedad. Razón por la cual, en este escrito se realizará un análisis de la teoría searleana de la conciencia, con el fin de proponer al lenguaje como elemento constitutivo de la naturaleza de este estado mental y no como producto derivado de la mente. Es decir, se propone una concepción biopragmática de la conciencia; estudio en el que se sustenta que biología y pragmática del lenguaje son condiciones sine qua non para la existencia de niveles superiores de la conciencia y superar el dualismo natural/social.

Although Symons' recent book, On Dennett (Wadsworth, 2002), provides scientists with ahelpful, general introduction to Dennett'sthought, it presents a skewed version of the history of the philosophy of mind. In particular, the continental tradition is almost entirely ignored, if not glibly dismissed. As aresult, the unwary reader of this book wouldnever realize that Dilthey, Sartre and Husserl,like Dennett, offer a ``middle ground'' between naturalistic realism and naturalistic eliminativism. However, unlike Dennett, the respective positions of Dilthey, Sartre and Husserl are not (...) ontologically indifferent, but instead, present a non-naturalistic form of realism that does not simultaneously invoke Cartesian dualism.

Daniel Dennett (1991) has advanced a mild realism in which beliefs are described as patterns “discernible in agents' (observable) behavior” (p. 30). I clarify the conflict between this otherwise attractive theory and the strong realist view that beliefs are internal states that cause actions. Support for strong realism is sometimes derived from the assumption that the everyday psychology of the folk is committed to it. My main thesis here is that we have sufficient reason neither for strong realism nor for (...) the supporting assumption about the commitments of folk psychology. Several generally implicit arguments in support of the latter assumption are considered. Explicit arguments for it by Ramsey et al. (1990) and Wellman (1990) are examined and judged unsuccessful. An explicit argument for strong realism by Cummins (in conversation) is also found inadequate. Consideration of this latter argument helps to explain why we cannot be satisfied with Dennett's own very brief discussion of causation by beliefs. (shrink)

Hidden nature physicalists hold that an experiential quality and its hidden nature are the same property – even though they agree that our experiences are of experiential qualities but are not, in the same sense, experiences of their hidden natures. This paper argues that physicalists must be committed to ultimately giving accounts that involve no non-extensional relations, and that this commitment leads to an inability to explain how our experiences could be of experiential qualities, but not of their hidden natures.

I argue that embryonic stem cell research is fair to the embryo, even on the assumption that the embryo has attained full personhood and an attendant right to life at conception. This is because the only feasible alternatives open to the embryo are to exist briefly in an unconscious state and be killed or to not exist at all. Hence, one is neither depriving the embryo of an enduring life it would otherwise have had nor is one causing the embryo (...) pain. I also argue that a rational agent in a situation relevantly similar to that of the embryo would consent to such research, and I use this insight to ground two justice-based arguments in favor of this research.

The encounter between the Christian Churches and Psychology has, for all its evident cultural importance, received little attention from disciplinary historians. During the period between the two world wars in Britain this encounter was particularly visible and, as it turned out, for the most part relatively amicable. Given their ostensive rivalry this is, on the face of it, somewhat surprising. Closer examination, however, reveals a substantial convergence and congruence of interests between them within the prevailing cultural climate, and considerable overlapping (...) of membership. The character of their meeting was, it is argued, determined more by these factors than by fundamental divergences in intellectual and theoretical orientation. Such divergences were diplomatically sidelined, on the religious side, by viewing Psychology as having certain ‘blind spots’ and, on the Psychology side, by invoking the argument that ‘science’ is concerned only with ‘facts’, not ‘values’. Only some hard-line psychoanalysts adopted an explicitly anti-religious stance. Religion’s concessions ultimately proved too high a price, and following this period the Churches began distancing themselves from Psychology. Their current relationship is very different from that which prevailed from 1918 to 1939. A fuller historical picture of the relationship between Psychology and religion awaits consideration of other sites and periods. (shrink)

Multiple realization was once taken to be a challenge to reductionist visions, especially within cognitive science, and a foundation of the “antireductionist consensus.” More recently, multiple realization has come to be challenged on naturalistic grounds, as well as on more “metaphysical” grounds. Within cognitive science, one focal issue concerns the role of neural plasticity for addressing these issues. If reorganization maintains the same cognitive functions, that supports claims for multiple realization. I take up the reorganization involved in language dysfunctions to (...) deal with questions concerned with multiple realization and neural plasticity. Beginning with Broca’s case for localization and the nineteenth century discussion of “reorganization,” and returning to more recent evidence for neural plasticity, I argue that, in the end, there is substantial support for multiple realization in cognitive systems; I further argue that this is wholly consistent with a recognition of methodological pluralism in cognitive science.
