I aim to provide some evidence that Husserl’s description of perceptual updating actually fits very nicely into the Bayesian Brain paradigm, articulated by Karl Friston and others, and that that paradigm, in turn, can be taken as an excellent example of “Neurophenomenology”. The apparently un-phenomenological Helmholtzian component of the Bayesian Brain paradigm, according to which what one consciously seems to see is a product of unconscious causal reasoning to the best explanation of one’s sensory stimulations, can be finessed, I claim, (...) in a way that makes it compatible with a phenomenological orientation. I begin by roughly characterizing the Bayesian Brain paradigm as it relates to perceptual cognition. I then show how Husserl’s descriptions of the conscious perceptual process relate to the paradigm. I conclude with some considerations about how to understand the relation between conscious and unconscious brain process in the present case and in relation to Neurophenomenology generally. (shrink)

This paper argues for a theory of phenomenal intentionality (herein referred to as ‘Structuralism’), according to which perceptual experiences only possess intentional content when their phenomenal components are appropriately related to one another. This paper responds to the objections (i) that Structuralism cannot explain why some experiences have content while others do not, or (ii) why contentful experiences have the specific contents that they have. Against (i), I argue that to possess content, an experience must present itself as an experience (...) of something distinct from itself, and that only experiences whose components are suitably structured satisfy this requirement. Against (ii), I argue that Structuralists can provide a deeper explanation of perceptual content than other theories of phenomenal intentionality by showing how the content-determining relations among our experiences depend on the selection pressures under which our perceptual systems developed.

Theories of phenomenal intentionality have been claimed to resolve certain worries about the indeterminacy of mental content that rival, externalist theories face. Thus far, however, such claims have been largely programmatic. This paper aims to improve on prior arguments in favor of phenomenal intentionality by using attention and Gestalt principles as specific examples of factors that influence the phenomenal character of perceptual experience in ways that thereby help determine perceptual content. Some reasons are then offered for rejecting an alternative interpretation (...) of these examples, according to which the phenomenal effects of attention and Gestalt principles play no role in the determination of perceptual content.

This paper investigates the claims made by both Freudian psychoanalysic thought and Husserlian phenomenology about the unconscious. First, it is shown how Husserl incorporates a complex notion of the unconscious in his analysis of passive synthesis. With his notion of an unintentional reservoir of past retentions, Husserl articulates an unconscious zone that must be activated from consciousness in order to come to life. Second, it is explained how Husserl still does not account for the Freudian unconscious. Freud's unconscious could be (...) called, in phenomenological terms, a repressed retentional zone that differs from both near and far retention. Finally, an analysis is offered for the significance of this psychoanalytic argument for phenomenology. Does phenomenology provide a complete account of the psychical life of the subject without the Freudian unconscious? Does phenomenology suggest, as is often done, that Freud's discovery of the unconscious is a fantastical invention? Or, does the Freudian unconscious represent a true stumbling block for phenomenology? (shrink)

Defenders of the extended mind thesis say that it is possible that some of our mental states may be constituted, in part, by states of the extra-bodily environment. Often they also add that such extended mentation is a commonplace phenomenon. I argue that extended mentation, while not impossible, is either nonexistent or far from widespread. Genuine beliefs as they occur in normal biologically embodied systems are informationally integrated with each other, and sensitive to changes in the person.

The quantum theory of de Broglie and Bohm solves the measurement problem, but the hypothetical corpuscles play no role in the argument. The solution finds a more natural home in the Everett interpretation.

I use the collection of “carnal ethnographies” of martial arts and combat sports assembled by Raul Sanchez and Dale Spencer under the title Fighting Scholars to spotlight the fruitfulness of deploying habitus as both empirical object (explanandum) and method of inquiry (modus cognitionis). The incarnate study of incarnation supports five propositions that clear up tenacious misconceptions about habitus and bolster Bourdieu’s dispositional theory of action: (1) far from being a “black box,” habitus is fully amenable to empirical inquiry; (2) the (...) distinction between primary (generic) and secondary (specific) habitus enables us to capture the malleability of dispositions; (3) habitus is composed of cognitive, conative and affective elements: categories, skills, and desires; (4) habitus allows us to turn carnality from problem to resource for the production of sociological knowledge; and (5) thus to realize that all social agents are, like martial artists, suffering beings collectively engaged in embodied activities staged inside circles of shared commitments.

In this paper, I want to hold, first, that a treatment of Frege cases in terms of a difference in cognitive phenomenology of the involved experiential mental states is not viable. Second, I will put forward another treatment of such cases that appeals to a difference in intentional objects metaphysically conceived not as exotica, but as schematic objects, that is, as objects that have no metaphysical nature qua objects of thought. This allows their nature to be settled independently of their (...) being thought of, in particular as concrete entities in the sense of entities that may be spatiotemporal occupiers. Yet third, as to Frege cases, cognitive phenomenology may return from the back door. For the realization that, if correct, solves any such case cannot but have a proprietary, though neither distinctive nor individuative, phenomenology. In my account, this is the realization that the different schematic intentional objects involved are none other than the same entity. (shrink)

As far as I can see, there are two basic ways of cashing out the claim that intentionality is ultimately phenomenal: an indirect one, according to which the intentional content of an experiential intentional mental state is determined by the phenomenal character that state already possesses, so that intentionality is so determined only indirectly; a direct one, which centers on the very property of intentionality itself and can further be construed in two manners: either that very property is determined by (...) the above phenomenal character, or it is a sui generis phenomenal property, thereby giving its own contribution to the overall phenomenal character of that state. Yet neither way sounds ultimately satisfying. For the indirect way may work only under the assumption that intentionality is monadic. Since the direct way explicitly endorses this assumption, the indirect way must give pride of place to it. Yet the direct way seems to be unsuccessful, in any of its forms. Thus, the phenomenal intentionality research program ought to give way to another research program concerning intentionality. (shrink)

I discuss two forms of the thesis that to have a sensation is to token a sentence in a language of thought-what I call, following Georges Rey, the sensational sentences thesis. One form of the thesis is a version of standard functionalism, while the other is a version of the increasingly popular thesis that for a sensation to have qualia is for it to have a certain kind of intentional content-that is, intentionalism. I defend the basic idea behind the sensational (...) sentences thesis, and argue that the intentionalist version is either false or collapses into the standard functionalist thesis. (shrink)

We identify two senses of ‘pragmatics’ and related terms that give rise to two different methods of propositional individuation. The first one is the contextualist approach that essentially acknowledges contextual information to take part in the determination of what is said by the utterance of a sentence. In this sense, Pragmatics relies on the Principle of Compositionality and interprets propositions as structured entities. It epitomises the Building-block Model of Propositional Individuation. The general approach that makes what the agents do the (...) grounding level of philosophical and linguistic analysis characterizes the second sense, Pragmatism. It finds its clearest expression in Peirce’s Pragmatist Maxim, and it relies on the Fregean Principle of Context, and supports a view of propositions as unstructured entities. This is the Organic Model of Propositional Individuation. There is a test, the Analytic Equivalence Test, that tells apart the two models. According to it, the answer to the question whether a theory makes room for different but analytically equivalent propositions determines the model the theory belongs in. A positive answer classifies the theory as belonging to the building-block model; a negative answer allocates the theory within the organic model. (shrink)

Physicalists commonly argue that conscious experiences are nothing more than states of the brain, and that conscious qualia are observer-independent, physical properties of the external world. Although this assumes the ‘mantle of science,’ it routinely ignores the findings of science, for example in sensory physiology, perception, psychophysics, neuropsychology and comparative psychology. Consequently, although physicalism aims to ‘naturalise’ consciousness, it gives an unnatural account of it. It is possible, however, to develop a natural, nonreductive, reflexive model of how consciousness relates to (...) the brain and the physical world. This paper introduces such a model and how it construes the nature of conscious experience. Within this model the physical world as perceived (the phenomenal world) is viewed as part of conscious experience not apart from it. While in everyday life we treat this phenomenal world as if it is the “physical world”, it is really just one biologically useful representation of what the world is like that may differ in many respects from the world described by physics. How the world as perceived relates to the world as described by physics can be investigated by normal science (e.g. through the study of sensory physiology, psychophysics and so on). This model of consciousness appears to be consistent with both third-person evidence of how the brain works and with first-person evidence of what it is like to have a given experience. It also views consciousness as an integral part and natural expression of the world—in a manner true to the spirit (if not to the detail) of Whitehead’s philosophy. -/- . (shrink)

One of the most interesting and entertaining philosophical discussions of the last few decades is the discussion between Daniel Dennett and John Searle on the existence of intrinsic intentionality. Dennett denies the existence of phenomena with intrinsic intentionality. Searle, however, is convinced that some mental phenomena exhibit intrinsic intentionality. According to me, this discussion has been obscured by some serious misunderstandings with regard to the concept ‘intrinsic intentionality’. For instance, most philosophers fail to realize that it is possible that the (...) intentionality of a phenomenon is partly intrinsic and partly observer relative. Moreover, many philosophers are mixing up the concepts ‘original intentionality’ and ‘intrinsic intentionality’. In fact, there is, in the philosophical literature, no strict and unambiguous definition of the concept ‘intrinsic intentionality’. In this article, I will try to remedy this. I will also try to give strict and unambiguous definitions of the concepts ‘observer relative intentionality’, ‘original intentionality’, and ‘derived intentionality’. These definitions will be used for an examination of the intentionality of formal mathematical systems. In conclusion, I will make a comparison between the (intrinsic) intentionality of formal mathematical systems on the one hand, and the (intrinsic) intentionality of human beings on the other hand.

1. Consider the basic outlines of the mind-body debate as it is found in contemporary Anglo-American analytic philosophy. The central question is “whether mental phenomena are physical phenomena, and if not, how they relate to physical phenomena.”1 Over the centuries, a wide range of possible solutions to this problem have emerged. These are the various “isms” familiar to any student of the debate: Cartesian dualism, idealism, epiphenomenalism, central state materialism, non- reductive physicalism, anomalous monism, and so forth. Each purports to (...) specify, among other things, the metaphysical relationship between the mental and the physical. They do so by specifying whether, or in what way, mental entities are identical to, reducible to, realized by, supervenient upon, or in causal interaction with physical entities. Thus, a convenient way to survey the range of positions is to enter them in a table. Rows correspond to the major kinds of metaphysical relation which might obtain between mental and physical entities. Each columns corresponds to one of the generic positions available in the debate. The particular theories defended by individual philosophers are usually just specific versions of generic positions. Thus Malebranche’s occasionalism is a version of causal dualism, distinguished by a peculiar account of the way in which causal interaction between mental and physical is actually effected. The central philosophical challenge is to determine which of these positions correctly describes the mental/physical relationship. Positions are evaluated for internal consistency, their fit with “intuitions,” their compatibility with scientific developments, and so forth. The mind-body debate, in this simple form, is set out in any number of. (shrink)

Consciousness exists, or so it seems to us most of the time. However, consciousness is unlike your car-keys or your cell-phone in that it is not located at a specific point in space and time. The applicability of physical laws like gravity seem moot at best when it comes to consciousness. What is desirable is an explanation of consciousness that allows it to exist and be part of the very same reality as the car-key or the cell-phone, a ‘philosophy of (...) immanence’ as Gilles Deleuze would put it. I prefer a view that construes consciousness as causally-efficacious and metaphysically separate from the brain. In essence, to say that the mind is metaphysically separate from the brain is to deny the proposition that there is nothing more to our subjective experience of mind than the mere activity of the physical brain. This paper looks at a view proposed by John Searle and tries to show that there are empirical problems with a consciousness that is causally inefficacious and metaphysically identical. (shrink)

Consciousness is seen as a difficult “binding” problem. Binding, a process where different sensations evoked by an item are associated in the nervous system, can be viewed as a process similar to associative learning. Several reports that consciousness is associated with some form of memory imply that different forms of memories have a common feature contributing to consciousness. Based on a proposed synaptic mechanism capable of explaining different forms of memory, we developed a framework for consciousness. It is based on (...) the formation of semblance of sensory stimulus from (1) synaptic semblances when excitatory postsynaptic potentials arrive at functionally LINKed postsynaptic membranes, and (2) network semblances when these potentials summate to elicit action potential initiating activity in a network of neurons. It is then possible to derive a framework for consciousness as a multi-dimensional semblance. According to this framework, a continuum of semblances formed from background sensory stimuli and oscillating neuronal activities serve to maintain consciousness. Feasibility of this framework to explain various physiological and pathological states of consciousness, its subjective nature and qualia is examined. (shrink)

The commodification of code demands two preconditions: a belief if the existence of code and a system of ownership for the code. An examination of these preconditions is helpful for resisting the further widening of digital divides. The ontological belief in the relatively independent existence of code is dependent on our understanding of what the “digital” is. Here it is claimed that the digital is not a natural kind, but a concept that is relative to our practices of interpretation. An (...) interpretative system that sees code as something that can or should always be owned implies an increase of social control and threatens vital processes of knowledge creation that are necessary for an open and egalitarian information society. The ontological belief in “digital code” thus provides the backdrop for an ethical view of the information society. Consequently, if we see digital code as an interpretative notion (in the nominalist way), the ethical questions appear in a different light. (shrink)

This essay argues that the philosophy of the Mengzi is not an idealism or naturalism which makes morality something innate. These interpretations are limited by Cartesian presuppositions of objectivity and subjectivity, which were not a part of the Mengzi’s philosophical repertoire. This essay rehearses the problem of subjectivity and objectivity in Western philosophy. It then argues that no such dichotomy informed the Mengzi; instead, it maintains that minds and their worlds are mutually entailing and constituting. It explores the relationship between (...) the concepts of heart-mind, human nature, and tian, arguing that heart-mind is the emergence of human nature which is the internalized interpretive framework of an external Confucian morality referred to as tian. It argues that humans are situated within historical traditions that provide their world horizons. There is no world beyond the Confucian world and no mind beyond the Confucian mind: the Mengzi is a realism with a Confucian face. (shrink)

One of the main challenges in the philosophy of language is determining the form of knowledge of the rules of language. Michael Dummett has put forth the view that knowledge of the rules of language is a kind of implicit knowledge; some philosophers have mistakenly conceived of this type of knowledge as a kind of knowledge-that . In a recent paper in this journal, Patricia Hanna argues against Dummett’s knowledge-that view and proposes instead a knowledge-how view in which knowledge of (...) the rules of language is a kind of practical knowledge, like an agent’s non-propositional knowledge of counting. In this paper I argue, first, that Hanna misunderstands Dummett’s conception of knowledge of linguistic rules, and, second, that Dummett’s considerations of practical knowledge of language pose a problem for Hanna’s knowledge-how view. At the end of the paper, I briefly sketch an account of practical knowledge of language that meets the requirements set by Dummett. (shrink)

Clinical fields of the “sciences of the mind” (psychotherapy, psychiatry, etc.) lack integrative conceptual frameworks that have explanatory power. Mainly descriptive-classificatory taxonomies like DSM dominate the field. New taxonomies such as Research Domain Criteria (RDoC) aim to collect scientific knowledge regarding “systems” for “processes” of the brain. These terms have a supradisciplinary” meaning if they are considered in context of Systems Science. This field emerges as a platform of theories like general systems theory, catastrophe theory, synergetics, chaos theory, etc. It (...) provides a lot of abstract concepts, constructs, methods and models. We assume that these tools also enable theoretical integration in the diversified field of clinical practice in the sciences of the mind. Additionally, systems thinking in clinical psychology improves conceptual links to currently network-oriented neurobiology. However, clear definitions of systemic terms are necessary to emerge from their mainly metaphorical use. Here we revise mainly terms like “structure”, “process” and “dynamics” as they are used already in psychology, psychoanalysis, psychopathology and psychiatry in an ill-defined way. For instance, affective-cognitive structures like “life space” or “object representations” can be seen as products of mental processing. These structures, in turn, modulate dynamics of mental processes. Additionally, we suggest a coupled network concept of emotions and motivations as the main subsystem that modulates mental dynamics that results in a qualitative systemic model of the mind. Finally, we assume that a revisited systemic approach could improve interdisciplinary understanding of the mental. ystem for mental dynamics. In this context, we assume that a revisited systemic approach could improve interdisciplinary understanding of the mental. (shrink)

In everyday discourse and in the context of social scientific research we often attribute intentional states to groups. Contemporary approaches to group intentionality have either dismissed these attributions as metaphorical or provided an analysis of our attributions in terms of the intentional states of individuals in the group.Insection1, the author argues that these approaches are problematic. In sections 2 and 3, the author defends the view that certain groups are literally intentional agents. In section 4, the author argues that there (...) are significant reasons for social scientists and philosophers of social science to acknowledge the adequacy of macro-level explanations that involve the attribution of intentional states to groups. In section 5, the author considers and responds to some criticisms of the thesis she defends. (shrink)

Can theories of mental imagery, conscious mental contents, developed within cognitive science throw light on the obscure (but culturally very significant) concept of imagination? Three extant views of mental imagery are considered: quasi‐pictorial, description, and perceptual activity theories. The first two face serious theoretical and empirical difficulties. The third is (for historically contingent reasons) little known, theoretically underdeveloped, and empirically untried, but has real explanatory potential. It rejects the “traditional” symbolic computational view of mental contents, but is compatible with recentsituated (...) cognition and active visionapproaches in robotics. This theory is developed and elucidated. Three related key aspects of imagination (non‐discursiveness, creativity, and seeing as) raise difficulties for the other theories. Perceptual activity theory presents imagery as non‐discursive and relates it closely to seeing as. It is thus well placed to be the basis for a general theory of imagination and its role in creative thought. (shrink)

I examine the abstraction/representation theory of computation put forward by Horsman et al., connecting it to the broader notion of modeling, and in particular, model-based explanation, as considered by Rosen. I argue that the ‘representational entities’ it depends on cannot themselves be computational, and that, in particular, their representational capacities cannot be realized by computational means, and must remain explanatorily opaque to them. I then propose that representation might be realized by subjective experience, through being the bearer of the structure (...) of abstract objects that are represented. (shrink)

Representationalist accounts of mental content face the threat of the homunculus fallacy. In collapsing the distinction between the conscious state and the conscious subject, self-representational accounts of consciousness possess the means to deal with this objection. We analyze a particular sort of self-representational theory, built on the work of John von Neumann on self-reproduction, using tools from mathematical logic. We provide an explicit theory of the emergence of referential beliefs by means of modal fixed points, grounded in intrinsic properties yielding (...) the subjective aspects of experience. Furthermore, we study complications introduced by allowing for the modification of such symbolic content by environmental influences. (shrink)

Standard accounts in social ontology and the group cognition debate have typically focused on how collective modes, types, and contents of intentions or representational states must be construed so as to constitute the jointness of the respective agents, cognizers, and their engagements. However, if we take intentions, beliefs, or mental representations all to instantiate some mental properties, then the more basic issue regarding such collective engagements is what it is for groups of individual minds to share a mind. Somewhat surprisingly, (...) this very issue has not received much attention in the respective debates and when it has, typically the outlook has been skeptical or outright negative. In this paper, I argue that it is epistemologically possible for a group of individuals to literally share a single mental unit. In particular, I will put forward and defend what I shall call the zombie conception of group minds. (shrink)

Do philosophers and ordinary people conceive of subjective experience in the same way? In this article, we argue that they do not and that the philosophical concept of phenomenal consciousness does not coincide with the folk conception. We first offer experimental support for the hypothesis that philosophers and ordinary people conceive of subjective experience in markedly different ways. We then explore experimentally the folk conception, proposing that for the folk, subjective experience is closely linked to valence. We conclude by considering (...) the implications of our findings for a central issue in the philosophy of mind, the hard problem of consciousness. (shrink)

The new methods of modern sciences can contribute to understand the genesis of mental illness, the disturbances in brain chemistry, physiology, anatomy or genetical information underlying different diseases of the nervous system. Understanding mental illness is not only challenging to science, but is also of great social importance. Moreover, the new developments of neurosciences put new lights on discussions such as brain-mind concepts, unity of mind, definition of consciousness and even definition of the person.For the majority of the scientists, it (...) is clear today that the mind can not be conceived any more as unique and indivisible. For philosophers, it is clear also that neuroscience influenced their vision of life and death: neurosciences are not strange to the debate whole-body death versus whole-brain death for instance. Modern scientific achievements have expanded our vision, allowing us to percieve previously unanticipated interrelationships between biological and psychological phenomena. The boundary between some behavioural and higher neural function studies and biology is arbitrary and changing. It has been imposed not by the natural contours of the disciplines, but by lack of knowledge. (shrink)

Colours and consciousness both present us with metaphysical problems. But what exactly are the problems? According to standard accounts, they are roughly the following. On the one hand, we have reason to believe, about both colour and consciousness, that they are identical with some familiar natural phenomena. But on the other hand, it is hard to see how these identities could obtain. I argue that this is an adequate characterisation of our metaphysical problem of colour, but a mischaracterisation of the (...) problem of consciousness. It mischaracterises the problem by presenting consciousness as more 'colour-like' than we have reason to take it to be. The real problem of consciousness is, I suggest, that almost nothing theoretically useful is known about this phenomenon at present. I also explore some implications of this perspective on the problem of consciousness. Given the shape of the problem, I argue that we can't rule out all forms of eliminativism about consciousness. Nor can we rule out that future research will close the ' explanatory gap' that consciousness gives rise to. (shrink)

This article will discuss the difficulties of providing a plausible account of rule following in the social realm. It will show that the cognitive model of rule following is not suited for this task. Nevertheless, revealing the inadequacy of the cognitive model does not justify the wholesale dismissal of understanding human practices as rule-following practices, as social theorists like Bourdieu or Dreyfus have argued. Instead it will be shown that rule-following behavior is best understood as being based on a set (...) of complex dispositions. In this manner one is able to account for the causal explanatory role of the notion of a rule. Key Words: rules • norms • explanation • Bourdieu • Winch. (shrink)

Organisations are computing systems. The university’s sports centre is a computing system for managing sports teams and facilities. The tenure committee is a computing system for assigning tenure status. Despite an increasing number of publications in group ontology, the computational nature of organisations has not been recognised. The present paper is the first in this debate to propose a theory of organisations as groups structured for computing. I begin by describing the current situation in group ontology and by spelling out (...) the thesis in more detail. I then present the example of a sports centre to illustrate why one might intuitively think of organisations as computing systems. To substantiate the thesis, I introduce Piccinini’s restrictive analysis of physical computation. As I show, organisations meet all criteria for being computing systems. Organisations are structured groups with the function of manipulating medium-independent vehicles according to rules. Furthermore, I argue for the modal claim that this is a necessary feature of organisations. Having sketched the computational account of organisations, I compare it to other proposals in the literature. (shrink)

I argue in this article that there is a mistake in Searle's Chinese room argument that has not received sufficient attention. The mistake stems from Searle's use of the Church-Turing thesis. Searle assumes that the Church-Turing thesis licences the assumption that the Chinese room can run any program. I argue that it does not, and that this assumption is false. A number of possible objections are considered and rejected. My conclusion is that it is consistent with Searle's argument to hold (...) onto the claim that understanding consists in the running of a program. (shrink)

This article proposes a new interpretation of the ontological significance of the Biblical statement ‘I am that I am’ that focuses on the relationship between the Heideggerian notion of the being that is beyond all entities and the German Idealist concern with the irreducibility of subjectivity. This focus is put forward as an effective way of philosophically elaborating what are argued to be the twin aspects of the statement—the being that transcends predication, and an irreducibly first person ontology. This elaboration (...) is performed by discussing the way in which these two themes have been approached at certain pertinent points in the history of metaphysics. With regard to the theme of transcendent being, an overview of the medieval Scholastic debates on the issue precedes a direct discussion of the Heideggerian position. As for the theme of the irreducibility of first person ontology, an overview of the relevant theories of the various German Idealist philosophers precedes a direct engagement with what Heidegger has to say on this issue. The overall argument here is that it is possible coherently to conceive of the pure being that transcends all entities in terms of the ‘I’ of an absolute subject without eliding the difference between being and entities, without succumbing to what Heidegger regards as an onto-theological oblivion of being.

This paper examines how new evil demon problems could arise for our access to the internal world of our own minds. I start by arguing that the internalist/externalist debate in epistemology has been widely misconstrued---we need to reconfigure the debate in order to see how it can arise about our access to the internal world. I then argue for the coherence of scenarios of radical deception about our own minds, and I use them to defend a properly formulated internalist view (...) about our access to our minds. The overarching lesson is that general epistemology and the specialized epistemology of introspection need to talk---each has much to learn from each other. (shrink)

The problem of multiple-computations discovered by Hilary Putnam presents a deep difficulty for functionalism (of all sorts, computational and causal). We describe in out- line why Putnam’s result, and likewise the more restricted result we call the Multiple- Computations Theorem, are in fact theorems of statistical mechanics. We show why the mere interaction of a computing system with its environment cannot single out a computation as the preferred one amongst the many computations implemented by the system. We explain why nonreductive (...) approaches to solving the multiple- computations problem, and in particular why computational externalism, are dualistic in the sense that they imply that nonphysical facts in the environment of a computing system single out the computation. We discuss certain attempts to dissolve Putnam’s unrestricted result by appealing to systems with certain kinds of input and output states as a special case of computational externalism, and show why this approach is not workable without collapsing to behaviorism. We conclude with some remarks about the nonphysical nature of mainstream approaches to both statistical mechanics and the quantum theory of measurement with respect to the singling out of partitions and observables.

Extensionalism, as I understand it here, is the view that physical reality consists exclusively of extensional entities. On this view, intensional entitities must either be eliminated in favor of an ontology of extensional entities, or be reduced to such an ontology, or otherwise be admitted as non-physical. In this paper I argue that extensionalism is a misguided philosophical doctrine. First, I argue that intensional phenomena are not confined to the realm of language and thought. Rather, the ontology of such phenomena (...) is intimately entwined with the ontology of properties. After providing some evidence to the popularity of extensionalism in contemporary analytic philosophy, I investigate the motivating reasons behind it. Considering several explanations, I argue that the main motivating reason is rooted in the identification of matter with extension, an identification which is one of the hallmarks of the mechanistic conception of nature inherited from the founding fathers of our modern scientific outlook. I then argue that such a conception is not only at odds with a robust ontology of properties but is also at odds with our best contemporary physics. Rather than vindicating extensionalism contemporary science undermines the position, and the lesson to be drawn from this surprising fact is that extensionalism needs no longer be espoused as a regulative ideal of naturalistic philosophy. I conclude by showing that the ontological approach to intensional phenomena advocated throughout the paper also gains support from an examination of the historical context within which ‘intension’ was first introduced as a semantic notion.

The semantic view of computation is the claim that semantic properties play an essential role in the individuation of physical computing systems such as laptops and brains. The main argument for the semantic view rests on the fact that some physical systems simultaneously implement different automata at the same time, in the same space, and even in the very same physical properties. Recently, several authors have challenged this argument. They accept the premise of simultaneous implementation but reject the semantic conclusion. (...) In this paper, I aim to explicate the semantic view and to address these objections. I first characterize the semantic view and distinguish it from other, closely related views. Then, I contend that the master argument for the semantic view survives the counter-arguments against it. One counter-argument is that computational individuation is not forced to choose between the implemented automata but rather always picks out a more basic computational structure. My response is that this move might undermine the notion of computational equivalence. Another counter-argument is that while computational individuation is forced to rely on extrinsic features, these features need not be semantic. My reply is that the semantic view better accounts for these extrinsic features than the proposed non-semantic alternatives. (shrink)

Putnam (Representations and reality. MIT Press, Cambridge, 1988) and Searle (The rediscovery of the mind. MIT Press, Cambridge, 1992) famously argue that almost every physical system implements every finite computation. This universal implementation claim, if correct, puts at the risk of triviality certain functional and computational views of the mind. Several authors have offered theories of implementation that allegedly avoid the pitfalls of universal implementation. My aim in this paper is to suggest that these theories are still consistent with a (...) weaker result, which is the nomological possibility of systems that simultaneously implement different complex automata. Elsewhere I (Shagrir in J Cogn Sci, 2012) argue that this simultaneous implementation result challenges a computational sufficiency thesis (articulated by Chalmers in J Cogn Sci, 2012). My focus here is on theories of implementation. After presenting the basic simultaneous implementation construction, I argue that these theories do not avoid the simultaneous implementation result. The conclusion is that the idea that the implementation of the right kind of automaton suffices for a possession of a mind is dubious. (shrink)

Most, if not all, philosophers agree that computers cannot learn what words refers to from raw text alone. While many attacked Searle’s Chinese Room thought experiment, no one seemed to question this most basic assumption. For how can computers learn something that is not in the data? Emily Bender and Alexander Koller ( 2020 ) recently presented a related thought experiment—the so-called Octopus thought experiment, which replaces the rule-based interlocutor of Searle’s thought experiment with a neural language model. The Octopus (...) thought experiment was awarded a best paper prize and was widely debated in the AI community. Again, however, even its fiercest opponents accepted the premise that what a word refers to cannot be induced in the absence of direct supervision. I will argue that what a word refers to _is_ probably learnable from raw text alone. Here’s why: higher-order concept co-occurrence statistics are stable across languages and across modalities, because language use (universally) reflects the world we live in (which is relatively stable). Such statistics are sufficient to establish what words refer to. My conjecture is supported by a literature survey, a thought experiment, and an actual experiment. (shrink)

An increasing number of philosophers have promoted the idea that mechanism provides a fruitful framework for thinking about the explanatory contributions of computational approaches in cognitive neuroscience. For instance, Piccinini and Bahar :453–488, 2013) have recently argued that neural computation constitutes a sui generis category of physical computation which can play a genuine explanatory role in the context of investigating neural and cognitive processes. The core of their proposal is to conceive of computational explanations in cognitive neuroscience as a subspecies (...) of mechanistic explanations. This paper identifies several challenges facing their mechanistic account and sketches an alternative way of thinking about the epistemic roles of computational approaches used in the study of brain and cognition. Drawing on examples from both low-level and systems-level computational neuroscience, I argue that at least some computational explanations of neural and cognitive processes are partially independent from mechanistic constraints.

The article discusses the relationship between John Searle’s doctrine of naturalism and various forms of materialism and dualism. It is argued that despite Searle’s protestations, his doctrine is not substantially differ- ent from the epiphenomenalistic property dualism, except for the admis- sion, in his later works, of the existence of an irreducible non-Humean self. In particular, his recognition that consciousness is unique in having an irreducible first-person ontology makes his disavowal of property du- alism purely verbalistic. As for epiphenomenalism, Searle’s (...) explanation of how consciousness can be efficacious without violating the causal clo- sure of the physical, by analogy with the causal efficacy of the higher level properties of physical objects that are supervenient on the microphysical, confuses causality and constitution (causal and constitutive superve- nience). It is also argued that Searle’s recognition of the existence of an irreducible non-Humean self that is responsible for decision-making sits badly both with his (property dualistic) view that conscious mental states are irreducibly first-personal states of the brain (rather than of the self) and with his (epiphenomenalistic) view that consciousness has no causal power in addition to that of the underlying neurobiology.

It is a standard understanding that we live in time. In fact, the whole physical world as described in sciences is based on the idea of objective time. For centuries, we have defined time ever so minutely, basing them on finer and finer event measurements that we do not even notice that we have made an inductive leap when it comes to time—we can measure time, so we experience time. In the current work, I wish to critique this inductive leap (...) and examine what it means to experience time. We are embodied and embedded cognitive agents, constrained by our body as well as in continuous interaction with our environment. So another way to ask the question of temporal experience would be—how embodied is time? I posit that experience of time spoken of in general literature is a linguistic construct, in that, the idea of experience of time overshadows the actual phenomenal contents of time perception. Moreover, time perception itself comes from a post-facto judgment of events. It has also been observed that the order of events in time can be altered to create an illusion of violation of causality itself. This points to the possibility that events are arranged in a temporal map that can be read off by higher cognitive substrates. In the current work, we go on to explore the nature of such a map as it emerges from an embodied mind. (shrink)

Dreyfus's model of expert skill acquisition is philosophically important because it shifts the focus on expertise away from its social and technical externalization in STS, and its relegation to the historical and psychological context of discovery in the classical philosophy of science, to universal structures of embodied cognition and affect. In doing so he explains why experts are not best described as ideologues and why their authority is not exclusively based on social networking. Moreover, by phenomenologically analyzing expertise from a (...) first person perspective, he reveals the limitations of, and sometimes superficial treatment that comes from, investigating expertise from a third person perspective. Thus, he shows that expertise is a prime example of a subject that is essential to science but can only be fully elaborated with the aid of phenomenological tools. However, both Dreyfus's descriptive model and his normative claims are flawed due to the lack of hermeneutical sensitivity. He assumes an expert's knowledge has crystallized out of contextual sensitivity plus experience, and that an expert has shed, during the training process, whatever prejudices, ideologies, hidden agendas, or other forms of cultural embeddedness, that person might have begun with. One would never imagine, from Dreyfus's account, that society could possibly be endangered by experts, only how society's expectations and actions could endanger experts. The stories of actual controversies not only shows things do not work the way Dreyfus claims, but also that it would be less salutary if they did. Such stories amount to counterexamples to Dreyfus's normative claims, and point to serious shortcomings in his arguments. (shrink)

The overriding question in contemporary philosophy is as follows: We now have a reasonably well-established conception of the basic structure of the universe. But it is not at all easy to reconcile the basic facts we have come to know with a certain conception we have of ourselves, derived in part from our cultural inheritance but mostly from our own experience. Various aspects of this question are examined, concerning consciousness, intentionality, language, rationality, free will, society and institutions, politics, and ethics.
