In this analysis I use the first regional Central America ethics code to discuss the wider problems of corruption and media complicity with central governments in the region. Luis Moreno Ocampo of Transparency International has noted that to understand corruption factors one must first study formalized rules for the system. Following Moreno's suggestion, in this article I focus on the code and the actions it inspired to highlight the widespread corrupt media practices of the region. Although the code had an (...) immediate effect, that effect has waned and in some cases has been forgotten. (shrink)
At least one of my professors told me that in order to write a good philosophy paper, one should always try to defend as little territory as possible. The danger of this advice is that although it may make one's points defensible, it may also make them not worth defending. In order to avoid both of these extremes, I am going to defend a relatively modest claim, which appears to be necessary but not sufficient for another more ambitious claim, which (...) itself is also necessary for another more ambitious claim, and so on for several layers. I will start with the most ambitious claim, and then work my way down until I come to the claim I believe I have some chance of defending. I will, however, continue to make references to the other layers, to help us remember why the more modest claims are worth thinking about. (shrink)
Paul Churchland's epistemology contains a tension between two positions, which I will call pragmatic pluralism and eliminative materialism. Pragmatic pluralism became predominant as Churchland's epistemology became more neurocomputationally inspired, which saved him from the skepticism implicit in certain passages of the theory of reduction he outlined in Scientific Realism and the Plasticity of Mind. However, once he replaces eliminativism with a neurologically inspired pragmatic pluralism, Churchland 1) cannot claim that folk psychology might be a false theory, in any significant sense (...) 2) cannot claim that the concepts of Folk psychology might be empty of extension and lack reference. 3) cannot sustain Churchland's criticism of Dennett's "intentional stance" . 4) cannot claim to be a form of scientific realism, in the sense of believing that what science describes is somehow realer that what other conceptual systems describe.

Although Dewey’s influence has remained strong amongst the community of educators, his reputation amongst philosophers has had a remarkably volatile history. He was unquestionably the most influential figure in American philosophy until his death in 1952. Almost immediately after his death, however, Dewey’s writings almost completely disappeared from the American philosophy syllabus. They were replaced by the analytic philosophers of the logical positivist tradition, who thought that philosophical problems could be solved by unraveling puzzles that came from a lack of (...) understanding of proper language use. After several decades, however, the inadequacies of this view became unavoidably obvious, and the next generation of analytically trained philosophers began to find themselves saying things that sounded remarkably like Dewey. Many analytic philosophers began to use the word “pragmatist” to describe some aspect of their positions: Quine, Churchland, Davidson, Feyerabend, Rorty, Putnam, among many others. Putnam and Rorty, in particular, have made a serious effort to restudy the original pragmatist texts, and reinterpret them for use in modern contexts. Not everyone is satisfied with their reinterpretations, however. Rorty, in particular has been criticized in some detail by Dewey scholars (see especially Saatkamp 1995). But Rorty admits that his ideas differ significantly from Dewey’s, because he is trying to revive only those aspects of Dewey’s ideas which are relevant for our times. I will argue, however, that those aspects of pragmatism which Rorty claims are the most relevant are actually the most out of date, and vice versa. (shrink)
I have assumed that consciousness exists, and that to redefine the problem as that of explaining how certain cognitive and behavioral functions are performed is unacceptable. . . .Like many people (materialists and dualists alike), I find this premise obvious, although I can no more "prove" it than I can prove that I am conscious. . . .there is no denying that such arguments - on either side - ultimately come down to a bedrock of intuition at some point.

Sellars and Dewey each isolated and critiqued different aspects of the atomistic epistemology of the logical positivists: Dewey labeled his target "Sensationalistic Empiricism", and Sellars labeled his "the Myth of the Given." The main theme of this paper will be the similarity and differences in their responses to this kind of philosophy, and how both responses can be clarified and strengthened by considering recent discoveries in Cognitive Neuroscience. What we have recently learned about neural architecture accounts for a distinction between (...) knowledge and experience that is a recurrent theme in both Sellars and Dewey. Dewey, however, made a sharper break from the positivists by seeing all experience as shaped by skills and abilities which were designed to acheive certain goals and were colored by emotions. The connectionist architecture used in Cognitive Neuroscience supports this view, as does the psychological research of J.J. Gibson. Once we consider the ways in which connectionist cognitive abilities differ from linguistic ones, Sellars' distinction between thoughts and sensations, and Dewey's distinction between knowledge and experience, can both be plausibly accounted for.

The moral psychology of sympathy is the linchpin of the sentimentalist moral theories of both David Hume and Adam Smith. In this paper, I attempt to diagnose the critical differences between Hume's and Smith's respective accounts of sympathy in order to argue that Smithian sympathy is more properly suited to serve as a basis for impartial moral evaluations and judgments than is Humean sympathy. By way of arguing this claim, I take up the problem of overcoming sympathetic partiality in the (...) construction of a moral point of view, acknowledged by both writers, as my primary platform. My contention is that Humean sympathy is too mechanistic to actually deliver an impartial adjudicatory perspective, and that Smithian sympathy, with its evaluative, imaginative components, succeeds where Hume's account falls short. The paper is comprised of six sections: (i) introductory remarks, (ii) a discussion of Humean sympathy, (iii) a discussion of Smithian sympathy and its distinctness, (iv) a critical analysis of Hume's attempt to correct for sympathetic partiality in the construction of the judicial spectator's general point of view, (v) a critical discussion of sympathetic partiality in Smithian sympathy & (vi) a critical analysis of Smith's construction of the impartial spectator perspective as a moral point of view.

Certain philosophers and scientists have noticed that there are data that do not seem to fit with the traditional view known as the Mind/Brain Identity theory (MBI). This has inspired a new theory about the mind known as the Hypothesis of Extended Cognition (HEC). Now there is a growing controversy over whether these data actually require extending the mind out beyond the brain. Such arguments, despite their empirical diversity, have an underlying form. They all are disputes over where to draw (...) the line between intrinsic and relational causal powers. The second-century Buddhist philosopher Nagarjuna deals with similar issues when he argues for a middle way between the two positions that were known in his time by the terms eternalism and nihilism. Eternalism, like MBI, asserts that the mind is a permanent enduring substance (although the two theories disagree as to how long mind endures). Nihilism argued that the mind had no intrinsic existence, and today some argue that HEC could lead us to a similar conclusion. Nagarjuna's argument for a middle way between these two extremes is similar to an argument that can be made for HEC. We can accept that neither the brain nor any other single physical item is identical to the mind without falling down the slippery slope that leads to "The mind does not really exist, and therefore we are one with everything." Nagarjuna was correct to say that the mind has conventional reality—that the mind exists even though there is no sharp border between the mind and the world. (shrink)
In the seventh paragraph of the post, you say "This question [which machine, if any or both, is conscious/] seems to be in principle unfalsifiable, and yet genuinely meaningful." (I'm assuming that you mean that any answer to it is unfalsifiable.) My neo-Carnapian intuitions diagnoses the problem right at this point. Forget about attributions of meaningless and all that stuff. Replace it in your statement with more pragmatically-oriented evaluative notions: theoretically fruitless, arbitray without even being helpful for any theoretical, experimental, (...) or practical purpose, and so on. Any answer to the question will be those. Thus the question is not worth pursuing, especially since the thought experiment is science fiction right now. A much more useful way to spend one's time is addressing frutiful questions, like the ones involved in constructing your postulated robots, or investigating neural mechanisms, and so on. So acknowledge the connection between unfalsifiability/verifiability/confirmability and theoretical and practical worthlessness (rather than "meaningless"). Then get on with the theoretically and empirically worthwhile questions. Many of the latter are quiter abstract and "philosophical," anyway (about the scope and limits of various methodologies, existing theories, and so on). Aren't those enough to occupy even the most abstract theorist's attention? Why puzzle about questions whose answers can't be rationally justified? (shrink)
Clark ends his appendix with a description of what he calls "dynamic computationalism", which he describes as an interesting hybrid between DST and GOFAI. My 'horseLISP" example could be described as an example of dynamic computationalism. It is clearly not as eliminativist as Van Gelder's computational governor example, for I am trying to come up with something like identities between computational entities and dynamic ones. Thus unlike other dynamicists, I am not doing what Clark calls "embracing a different vocabulary for (...) the understanding and analysis of brain events". I think we probably can keep much of the computational vocabulary, although the meanings of many of its terms will probably shift as much as the meaning of 'atom' has shifted since Dalton's time. The label of "dynamic computationalism" is perhaps as good a description of my position as any, but I think I would mean something slightly different by it than Clark would. (For the following, please insert the mantra "of course, this is an empirical question" (OCTEQ) every paragraph or so.). (shrink)
I propose a semi-eliminative reduction of Fodors concept of module to the concept of attractor basin which is used in Cognitive Dynamic Systems Theory (DST). I show how attractor basins perform the same explanatory function as modules in several DST based research program. Attractor basins in some organic dynamic systems have even been able to perform cognitive functions which are equivalent to the If/Then/Else loop in the computer language LISP. I suggest directions for future research programs which could find similar (...) equivalencies between organic dynamic systems and other cognitive functions. This type of research could help us discover how (and/or if) it is possible to use Dynamic Systems Theory to more accurately model the cognitive functions that are now being modeled by subroutines in Symbolic AI computer models. If such a reduction of subroutines to basins of attraction is possible, it could free AI from the limitations that prompted Fodor to say that it was impossible to model certain higher level cognitive functions.

To some degree, Fodor's claim that Cognitive science divides the mind into modules tells us more about the minds doing the studying than the mind being studied. The knowledge game is played by analyzing an object of study into parts, and then figuring out how those parts are related to each other. This is the method regardless of whether the object being studied is a mind or a solar system. If a module is just another name for a part, then (...) to say that the mind consists of modules is simply to say that it is comprehensible. Fodor comes close to acknowledging this in the following passage. (shrink)
Darwinian atheists ridicule the “God of the Gaps” argument, claiming that it is theology and/or metaphysics masquerading as science.This is true as far as it goes, but Darwinian atheism relies on an argument which is equally metaphysical, which I call the “No Gaps,No God” argument. This atheist argument is metaphysical because it relies on a kind of conceptual necessity, rather than scientificobservations or experiments. “No Gaps No God” is a much better metaphysical argument than “God of the Gaps,” because the (...) latteris based on a clearly false conditional inference. However, there are also good, but not decisive, arguments against the “No Gaps NoGod” argument. Because metaphysical arguments never resolve as decisively as scientific research questions, there will probablyalways be a legitimate controversy at the metaphysical level on this topic, even though there is no serious controversy about Darwinianscience itself. If this fact were more widely acknowledged, it could help to defuse the controversy over teaching Darwin in the public schools. (shrink)

It is remarkable how similar today's mind-body debates are to the philosophical critiques of biological science, such as Henri Bergson's Vitalism at the turn of the last century. Philosophers like Bergson became famous arguing that science could never account for life. One reason was that living creatures could not be decomposed into fundamental units, in spite of the empirical finding that all animate things consist of basic cells with remarkably general properties in a bewildering profusion of variation. Today we know (...) that each of those cells has nearly identical DNA-RNA mechanisms, and that, to give one example, humans have about 50% of DNA in common with such creatures as yeast and C. elegans, the tiny worms that is now almost completely defined in genotype and phenotype. The cell and its genetic machinery can plausibly be called the atom of life. So Bergson's anti-atomism was wrong in large part. Indeed, had we followed his advice about 1900, we would still be living in the first great industrial age. (shrink)
I am grateful to Markate Daly for forcing me to clarify my concept of the relationship between experience and know-how. She may be correct in saying that "None of the passive endurings and sufferings, loves, enjoyments and imaginings of Dewey's conception can be characterized as a part of 'knowing how' as it is currently understood." But I think that there is a similarity between passive experience and active coping that distinguishes them both from the allegedly "objective" sense data that Dewey (...) was rejecting. Experiences of love and suffering don't simply present themselves to us as independent entities. They are richly interwoven with each other and with the world, in much the same way as the connections between muscles and perceptual affordances. I tried to explain why I saw both emotions and knowing-how affordances to be governed by the same principles in the section of the paper dealing with Gibson, but of course there is still a great deal more to be said.

The unity of mind and body need not imply accepting the unity of mind and brain, because the mind-brain identity is something that science has presupposed, not discovered. I cite evidence from modern neuroscience that cognitive activities are distributed throughout the human nervous system, which challenges the 'scientific' assumption (believed by Descartes, among others) that the brain is the seat of the soul, and the rest of the nerves are mere message cables to the brain. Dennett comes close to accepting (...) this point when he criticizes 'Cartesian materialism', and yet he still claims that Vie head is headquarters'. Accepting that the mind is the entire nervous system solves some philosophical problems, for Dennett and others. There is also some evidence that indicates that some cognitive activities may be hormonal rather than neural, which raises some challenging problems for the once obvious distinction between causing a mental state and embodying that state.

He describes his position as "neo-Carnapian", i.e. he is claiming that even if the question is meaningful, that doesn't mean it's worth looking into. He's probably right, in the sense that anyone can be right about a personal evaluative choice. And until I started questioning the belief that there is only one kind of physical process that could embody consciousness, I felt the same way myself. But the point about this thought experiment is that the current state of cognitive science (...) offers us two possible candidates for the embodiment of mind. And as Bickle points out, it seems like nothing we can imagine discovering in the future could settle this problem one way or the other. If this is true, this means that, strictly speaking, all this talk about being on the verge of a scientific understanding of consciousness is hype: No matter how close we get to solving the Chalmersian easy problems, we are getting nowhere nearer to solving the hard problem. If this is true, Cognitive Scientists ought to change their description of what they are doing, even if it cuts back on publicity and grant money. But I don't want to believe this, and I think the only way to avoid believing this is to discover the presuppositions that compel this belief, and see if we can change them. It's a dirty little job, but somebody has to do it, and philosophers seem less unqualified to attempt it than anyone else. Note, however, that I am not claiming we can use a thought experiment all by itself to find the answer, the way Searle claimed that the Chinese Room experiment supposedly proved that a computer couldn't be conscious. As RONALD LEMMEN points out, the fact that we can imagine something doesn't tell us anything about the world, only about our concepts of the world. Remember that the conclusion of my thought experiment was a question, not an answer. My only goal is to help clarify the question. (shrink)
Daniel Dennett has offered a helpful framework in which to consider the evolution of mind, calling it "the tower of generate and test" (1995, 1996). On the bottom of the tower there are "Darwinian creatures," whose patterns of behavior result from the effects of natural selection alone. Next come "Skinnerian creatures," whose behaviors continue to be modified during their individual lifetimes by trial, reward and punishment. Third are "Popperian creatures," capable of learning, as well, by trying things out in their (...) heads. Last are "Gregorian creatures," who learn through interaction with culture. I have spent some time trying to construct a similarly broad and rough framework in which to consider the evolution of mind, but focused on the development of inner representational systems. The idea was to explore possible forms of representation first within perception and then within thought as it becomes freed from perception. As I progressed, however, this fairly simply conceived project was soon out of hand. At times I thought I must be trying to reconstruct Kant's.. (shrink)
After reading this paper, Richard Rorty sent the following comment: Doubtless in some sense I am doing "epistemology" and for all I know the name will survive as that of something which has little to do with Kant. But I am not convinced that philosophers are making themselves as useful to cognitive science as they claim, or that cognitive science is more than an awkward place-holder for neurology. My hunch is that when neurology comes into its own, notions like "cognition" (...) will dry up and blow away. (See Michael Williams UNNATURAL DOUBTS for a good argument that 'knowledge' or 'cogntion' is not profitably thought of as a natural kind.). (shrink)
1. Throughout the paper, and especially in the section called "LISP vs. DST", I worried that there was not enough focus on EXPLANATION. For the real question, it seems to me, is not whether some dynamical system can implement human cognition, but whether the dynamical description of the system is more explanatorily potent than a computational/representational one. Thus we know, for example, that a purely physical specification can fix a system capable of computing any LISP function. But from this it (...) doesn't follow that the physical description is the one we need to understand the power of the system considered as an information processing device. In the same way, I don't think your demonstration that bifurcating attractor sets can yield the same behavior as a LISP program goes any way towards showing that we should not PREFER the LISP description. To reduce symbolic stories to a subset of DST (as hinted in that section) requires MORE than showing this kind of equivalence: it requires showing that there is explanatory gain, or at the very least, no explanatory loss, at that level. I append an extract from a recent paper of mine that touches on these issues, in case it helps clarify what I am after here. (shrink)
My claim that Skinner believed in psychological atoms is actually strengthened by Baars' remark that Skinner's behaviorist atoms could take a variety of physical forms. ( "A rat in a box could depress the bar by sitting on it, by using its paws, or biting it: these physically different responses were functionally equivalent operant behaviors.") Baars is correct that Pavlov, unlike Skinner, thought that psychological atoms were identical to certain physiological items. But Skinner, as a non-reductive (...) atomist, thought he could permit his psychological atoms to have a variety of physical forms. He still believed that even though each S-R connection was not really physical, it could nevertheless be understood as being independent of all other S-R connections ,and without reference to the laws of physics. It doesn't really make sense to speak of something as being both ontologically determined by its function, and ontologically independent, but philosophical clarity was not Skinner's strong point.

I should say, before beginning, that I am hearing what you say about Rorty now from the perspective on his work I have (for the time being, at least) as a result of having heard a working paper he presented to the scholars’ workshop of which I was a member at The Getty this winter, and then participating with him in a 4-hour discussion (and following small dinner gathering). I have also recently read his curious rather autobiographical essay, "Trotsky and (...) Wild Orchids," and that too has had some effect. So, I think I am speaking about my sense of where Rorty is now with his thinking, rather than primarily about the Rorty who is contained in the works you are discussing. You might say that whether I am at all right or quite wrong, I am speaking about what I understand to be a person’s evolving thinking, and you are speaking about a body of work bearing a name, Rorty. These are never, of course, quite the same, but engagement of the two is always at least interesting (perhaps particularly so to those of us interested more in philosophizing than in Philosophy, if I may put it that way).

Abstract In his discourses on ‘the lily of the field and the bird of the air,’ Kierkegaard presents faith as the best possible response to our precarious and uncertain condition, and as the ideal way to cope with the insecurities and concerns that his readers will recognize as common features of human existence. Reading these discourses together, we are introduced to the portrait of a potential believer who, like the ‘divinely appointed teachers’—the lily and the bird—succeeds in leading a life (...) that is full of care, but free of worry. Such a portrait, we claim, echoes Kierkegaard’s portrait of the knight of faith in Fear and Trembling . In this essay we suggest that faith, as characterized in the ‘lily and bird’ discourses, is a kind of existential trust that would allow us to overcome worry, while remaining wholeheartedly engaged in the finite realm of our cares and concerns. We claim that Kierkegaard’s goal in these discourses is not to belittle our earthly cares, but to invite us to develop a modified attitude toward all that we are susceptible to worry about.

In both psychology and philosophy, cognitive theories of emotion have met with increasing opposition in recent years. However, this apparent controversy is not so much a gridlock between antithetical stances as a critical debate in which each side is being forced to qualify its position in order to accommodate the other side of the story. Here, I attempt to sort out some of the disagreements between cognitivism and its rivals, adjudicating some disputes while showing that others are merely superficial. Looking (...) at evidence from neuroscience and social psychology, as well as thought experiments and theoretical arguments, I conclude that it is necessary to acknowledge both that emotions have intentional content and that they involve somatic agitation. I also point out some of the more promising directions for future research in this area. (shrink)
The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in (...) parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language. Key Words: efference copies; emulation theory of representation; forward models; Kalman filters; motor control; motor imagery; perception; visual imagery. (shrink)
William James’ Principles of Psychology, in which he made famous the ‘specious present’ doctrine of temporal experience, and Edmund Husserl’s Zur Phänomenologie des inneren Zeitbewusstseins, were giant strides in the philosophical investigation of the temporality of experience. However, an important set of precursors to these works has not been adequately investigated. In this article, we undertake this investigation. Beginning with Reid’s essay ‘Memory’ in Essays on the Intellectual Powers of Man, we trace out a line of development of ideas about (...) the temporality of experience that runs through Dugald Stewart, Thomas Brown, William Hamilton, and finally the work of Shadworth Hodgson and Robert Kelly, both of whom were immediate influences on James (though James pseudonymously cites the latter as ‘E.R. Clay’). Furthermore, we argue that Hodgson, especially his Metaphysic of Experience (1898), was a significant influence on Husserl. (shrink)
Two very different insights motivate characterizing the brain as a computer. One depends on mathematical theory that defines computability in a highly abstract sense. Here the foundational idea is that of a Turing machine. Not an actual machine, the Turing machine is really a conceptual way of making the point that any well-defined function could be executed, step by step, according to simple 'if-you-are-in-state-P-and-have-input-Q-then-do-R' rules, given enough time (maybe infinite time) [see COMPUTATION]. Insofar as the brain is a device whose (...) input and output can be characterized in terms of some mathematical function -- however complicated -- then in that very abstract sense, it can be mimicked by a Turning machine. Given what is known so far brains do seem to depend on cause-effect operations, and hence brains appear to be, in some formal sense, equivalent to a Turing machine [see CHURCH-TURING THESIS]. On its own, however, this reveals nothing at all of how the mind-brain actually works. The second insight depends on looking at the brain as a biological device that processes information from the environment to build complex representations that enable the brain to make predictions and select advantageous behaviors. Where necessary to avoid ambiguity, we will refer to the first notion of computation as algorithmic computation, and the second as information processing computation. (shrink)
A number of recent attempts to bridge Husserlian phenomenology of time consciousness and contemporary tools and results from cognitive science or computational neuroscience are described and critiqued. An alternate proposal is outlined that lacks the weaknesses of existing accounts.
Using the Gödel Incompleteness Result for leverage, Roger Penrose has argued that the mechanism for consciousness involves quantum gravitational phenomena, acting through microtubules in neurons. We show that this hypothesis is implausible. First, the Gödel Result does not imply that human thought is in fact non algorithmic. Second, whether or not non algorithmic quantum gravitational phenomena actually exist, and if they did how that could conceivably implicate microtubules, and if microtubules were involved, how that could conceivably implicate consciousness, is entirely (...) speculative. Third, cytoplasmic ions such as calcium and sodium are almost certainly present in the microtubule pore, barring the quantum mechanical effects Penrose envisages. Finally, physiological evidence indicates that consciousness does not directly depend on microtubule properties in any case, rendering doubtful any theory according to which consciousness is generated in the microtubules.

I examine one of the conceptual cornerstones of the field known as computational neuroscience, especially as articulated in Churchland et al. (1990), an article that is arguably the locus classicus of this term and its meaning. The authors of that article try, but I claim ultimately fail, to mark off the enterprise of computational neuroscience as an interdisciplinary approach to understanding the cognitive, information-processing functions of the brain. The failure is a result of the fact that the authors provide no (...) principled means to distinguish the study of neural systems as genuinely computational/information-processing from the study of any complex causal process. I then argue for two things. First, that in order to appropriately mark off computational neuroscience, one must be able to assign a semantics to the states over which an attempt to provide a computational explanation is made. Second, I show that neither of the two most popular ways of trying to effect such content assignation -- informational semantics and 'biosemantics' -- can make the required distinction, at least not in a way that a computational neuroscientist should be happy about. The moral of the story as I take it is not a negative one to the effect that computational neuroscience is in principle incapable of doing what it wants to do. Rather, it is to point out some work that remains to be done. (shrink)
b>: The problem of how physical systems, such as brains, come to represent themselves as subjects in an objective world is addressed. I develop an account of the requirements for this ability that draws on and refines work in a philosophical tradition that runs from Kant through Peter Strawson to Gareth Evans. The basic idea is that the ability to represent oneself as a subject in a world whose existence is independent of oneself involves the ability to represent space, and (...) in particular, to represent oneself as one object among others in an objective spatial realm. In parallel, I provide an account of how this ability, and the mechanisms that support it, are realized neurobiologically. This aspect of the article draws on, and refines, work done in the neurobiology and psychology of egocentric and allocentric spatial representation. (shrink)
Philosophy interfaces with cognitive science in three distinct but related areas. First, there is the usual set of issues that fall under the heading of philosophy of science (explanation, reduction, etc.), applied to the special case of cognitive science. Second, there is the endeavor of taking results from cognitive science as bearing upon traditional philosophical questions about the mind, such as the nature of mental representation, consciousness, free will, perception, emotions, memory, etc. Third.
... there are cases in which on the basis of a temporally extended content of consciousness a unitary apprehension takes place which is spread out over a temporal interval (the so-called specious present). ... That several successive tones yield a melody is possible only in this way, that the succession of psychical processes are united "forthwith" in a common structure.
This brief commentary has three goals. The first is to argue that ‘‘framework debate’’ in cognitive science is unresolvable. The idea that one theory or framework can singly account for the vast complexity and variety of cognitive processes seems unlikely if not impossible. The second goal is a consequence of this: We should consider how the various theories on offer work together in diverse contexts of investigation. A final goal is to supply a brief review for readers who are compelled (...) by these points to explore existing literature on the topic. Despite this literature, pluralism has garnered very little attention from broader cognitive science. We end by briefly considering what it might mean for theoretical cognitive science. (shrink)

There is a definite challenge in the air regarding the pivotal notion of internal representation. This challenge is explicit in, e.g., van Gelder, 1995; Beer, 1995; Thelen & Smith, 1994; Wheeler, 1994; and elsewhere. We think it is a challenge that can be met and that (importantly) can be met by arguing from within a general framework that accepts many of the basic premises of the work (in new robotics and in dynamical systems theory) that motivates such scepticism in the (...) first place. Our strategy will be as follows. We begin (Section 1) by offering an account (an example and something close to a definition) of what we shall term Minimal Robust Representationalism (MRR). Sections 2 & 3 address some likely worries and questions about this notion. We end (Section 4) by making explicit the conditions under which, on our account, a science (e.g., robot- ics) may claim to be addressing cognitive phenomena. (shrink)
b>: In this article I outline, apply, and defend a theory of natural representation. The main consequences of this theory are: i) representational status is a matter of how physical entities are used, and specifically is not a matter of causation, nomic relations with the intentional object, or information; ii) there are genuine (brain-)internal representations; iii) such representations are really representations, and not just farcical pseudo-representations, such as attractors, principal components, state-space partitions, or what-have-you;and iv) the theory allows us to (...) sharply distinguish those complex behaviors which are genuinely cognitive from those which are merely complex and adaptive.

Numerous philosophical theories of joint agency and its intentional structure have been developed in the past few decades. These theories have offered accounts of joint agency that appeal to higher-level states (such as goals, commitments, and intentions) that are ?shared? in some way. These accounts have enhanced our understanding of joint agency, yet there are a number of lower-level cognitive phenomena involved in joint action that philosophers rarely acknowledge. In particular, empirical research in cognitive science has revealed that when individuals (...) engage in a joint activity such as conversation or joint problem solving, they become aligned at multiple levels (e.g., behaviors, or cognitive states). We argue that this phenomenon of alignment is crucial to understanding joint actions and should be integrated with philosophical approaches. In this paper, we sketch a possible integration, and draw out its implications for understanding of joint agency and collective intentionality. The result is a process-based, dynamic account of joint action that integrates both low-level and high-level states, and seeks to capture the separate processes of how a joint action is initiated and sustained.

I argue against a growing radical trend in current theoretical cognitive science that moves from the premises of embedded cognition, embodied cognition, dynamical systems theory and/or situated robotics to conclusions either to the effect that the mind is not in the brain or that cognition does not require representation, or both. I unearth the considerations at the foundation of this view: Haugeland's bandwidth-component argument to the effect that the brain is not a component in cognitive activity, and arguments inspired by (...) dynamical systems theory and situated robotics to the effect that cognitive activity does not involve representations. Both of these strands depend not only on a shift of emphasis from higher cognitive functions to things like sensorimotor processes, but also depend on a certain understanding of how sensorimotor processes are implemented - as closed-loop control systems. I describe a much more sophisticated model of sensorimotor processing that is not only more powerful and robust than simple closed-loop control, but for which there is great evidence that it is implemented in the nervous system. The is the emulation theory of representation, according to which the brain constructs inner dynamical models, or emulators, of the body and environment which are used in parallel with the body and environment to enhance motor control and perception and to provide faster feedback during motor processes, and can be run off-line to produce imagery and evaluate sensorimotor counterfactuals. I then show that the emulation framework is immune to the radical arguments, and makes apparent why the brain is a component in the cognitive activity, and exactly what the representations are in sensorimotor control. (shrink)
I have argued elsewhere that imagery and represention are best explained as the result of operations of neurally implemented emulators of an agent's body and environment. In this article I extend the theory of emulation to address perceptual processing as well. The key notion will be that of an emulator of an agent's egocentric behavioral space. This emulator, when run off-line, produces mental imagery, including transformations such as visual image rotations. However, while on-line, it is used to process information from (...) sensory systems, resulting in perception (in this regard, the theory is similar to that proposed by Kosslyn (1994)). This emulator is what provides the theory in theory-laden perception. I close by arguing briefly that the spatial character of perception is to be explained as the contribution of the egocentric behavioral space emulator. (shrink)
An attempt is made to defend a general approach to the spatial content of perception, an approach according to which perception is imbued with spatial content in virtue of certain kinds of connections between perceiving organism's sensory input and its behavioral output. The most important aspect of the defense involves clearly distinguishing two kinds of perceptuo-behavioral skills—the formation of dispositions, and a capacity for emulation. The former, the formation of dispositions, is argued to by the central pivot of spatial content. (...) I provide a neural information processing interpretation of what these dispositions amount to, and describe how dispositions, so understood, are an obvious implementation of Gareth Evans' proposal on the topic. Furthermore, I describe what sorts of contribution are made by emulation mechanisms, and I also describe exactly how the emulation framework differs from similar but distinct notions with which it is often unhelpfully confused, such as sensorimotor contingencies and forward models.

Recent allegations of unethical decision-making by leaders in prominent business organizations have jeopardized the world’s confidence in American business. The purpose of this research was to develop a measure of managerial moral judgment that can be used in future research and managerial assessment. The measure was patterned after the Defining Issues Test, a widely used general measure of moral judgment. With content validity as the goal, we aimed to sample the domain of managerial ethical situations by establishing links to dimensions (...) of managerial performance, as well as to the types of organizational justice issues managers encounter. Proposed scenarios were evaluated for realism by ethics officers and human resource managers. Results indicated that the new measure is reliable and correlates with a number of relevant variables in the hypothesized manner, demonstrating evidence of construct validity. Implications for future research and for human resources management are discussed. (shrink)
Two very different insights motivate characterizing the brain as a computer. One depends on mathematical theory that defines computability in a highly abstract sense. Here the foundational idea is that of a Turing machine. Not an actual machine, the Turing machine is really a conceptual way of making the point that any well-defined function could be executed, step by step, according to simple 'if-you-are-in-state-P-and-have-input-Q-then-do-R' rules, given enough time (maybe infinite time) [see COMPUTATION]. Insofar as the brain is a device whose (...) input and output can be characterized in terms of some mathematical function -- however complicated -- then in that very abstract sense, it can be mimicked by a Turning machine. Given what is known so far brains do seem to depend on cause-effect operations, and hence brains appear to be, in some formal sense, equivalent to a Turing machine [see CHURCH-TURING THESIS]. On its own, however, this reveals nothing at all of how the mind-brain actually works. The second insight depends on looking at the brain as a biological device that processes information from the environment to build complex representations that enable the brain to make predictions and select advantageous behaviors. Where necessary to avoid ambiguity, we will refer to the first notion of computation as. (shrink)
[1] It is well-known that Evans laid the groundwork for a truly radical and fruitful theory of _content_ -- a theory according to which content is a genus with at least conceptual and nonconceptual varieties as species, and in which nonconceptual content plays a very significant role. It is less well-recognized that Evans was also in the process of working out the details of a truly radical and groundbreaking theory of _representation_, a task he was unfortunately unable to bring to (...) any satisfactory stage of fruition. I am here drawing the distinction between a theory of. (shrink)
Nothing is more obvious than the fact that we are able to experience events in the world such a ball deflecting from the cross-bar of a goal. But what is the temporal relation between these two things, the event, and our experience of the event? One possibility is that the world progresses temporally through a sequence of instantaneous states – the striker’s foot in contact with the ball, then the ball between the striker and the goal, then the ball in (...) contact with the cross-bar, and so forth –, while the perceiver’s experience is likewise a sequence of experience states, each one of which corresponds to, or is experience of, a corresponding state of the world – for example, a perception of the foot in contact with the ball, followed by a perception of the ball in the air, following by a perception of the ball in contact with the cross-bar. This way of understanding the relationship between experience and the world is very natural, and nearly universal. However, it rests on two assumptions that can be brought into question. (shrink)
William James' Principles of Psychology , in which he made famous the "specious present" doctrine of temporal experience, and Edmund Husserl's Zur Phänomenologie des inneren Zeitbewusstseins were giant strides in the philosophical investigation of the temporality of experience. However, an important set of precursors to these works has not been adequately investigated. In this article, we undertake this investigation. Beginning with Reid's essay "Memory" in Essays on the Intellectual Powers of Man , we trace out a line of development of (...) ideas about the temporality of experience that runs through Dugald Stewart, Thomas Brown, William Hamilton, and finally the work of Shadworth Hodgson and Robert Kelly, both of whom were immediate influences on James (though James pseudonymously cites the latter as 'E.R. Clay'). Furthermore, we argue that Hodgson, especially his Metaphysic of Experience (1898), was a significant influence on Husserl. (shrink)
In this paper I will outline a unified information processing framework whose goal is to explain how the nervous system represents space, time and objects. In the remainder of this introductory section I will first be more specific about the sort of spatial, temporal, and object representation at issue, and then outline the structure of this paper.
: Berkeley's Essay Towards a New Theory of Vision presents a theory of various aspects of the spatial content of visual experience that attempts to undercut not only the optico-geometric accounts of e.g., Descartes and Malebranche, but also elements of the empiricist account of Locke. My task in this paper is to shed light on some features of Berkeley's account that have not been adequately appreciated. After rehearsing a more detailed Lockean critique of the notion that depth is a proper (...) object of vision, Berkeley directs arguments he takes to be entirely parallel against the notion that vision has two-dimensional planar contents as proper objects. I show that this argument fails due to an illicit slide unnoticed by both Berkeley and his commentators—a slide present but innocuously so in the case of depth. Berkeley's positive account, according to which the apparent spatial content of vision is a matter of associations between, on the one hand, tactile and motor contents, and on the other hand non-spatial visual contents, also fails because of an illicit slide—again, unnoticed by Berkeley and his commentators. I close by discerning the salvageable and correct core of Berkeley's theory of the spatiality of vision. (shrink)
This article discusses the way in which a group of contemporary cultural theorists in whose work we see a “new materialism” (a term coined by Braidotti and DeLanda) at work constitutes a philosophy of difference by traversing the dualisms that form the backbone of modernist thought. Continuing the ideas of Lyotard and Deleuze they have set themselves to a rewriting of all possible forms of emancipation that are to be found. This rewriting exercise involves a movement in thought that, in (...) the words of Bergson, can be termed “pushing dualism to an extreme.” By this movement, Deleuze has stated, “difference is pushed to the limit,” that is, using Colebrook’s words, “difference is shown differing.” The article addresses the ways in which modernity’s dualisms (structured by a negative relation between terms) are traversed, and how a new conceptualization, and ontology , of difference (structured by an affirmative relation) comes to be constituted along the way. New materialism leaves behind all prioritizations (implicitly) involved in modern dualist thinking since a difference structured by affirmation does not work with predetermined relations (e.g., between mind and body) nor does it involve a (counter-)hierarchy between terms. The article makes explicit the methodology of the current-day rise of non-dualist thought, both in terms of its non-classificatory mode of (Deleuzian) thinking and in terms of the theory of the time of thought thus effectuated (Lyotard’s notion of ‘rewriting modernity’ is not a post-modernism). Throughout the article we will engage with an example in order to demonstrate the ontology that is being practiced following this methodology: How does a new (feminist) materialism traverse the sexual dualisms that structure modernist (feminist) thinking? This example also shows how a feminist post-modernism (found in the canonical work of Butler) has remained dualist, and what makes new materialism “new.” Freed from a dualist methodology, the modernist emancipatory project comes to full fruition in new materialism.

0. Introduction The past decade has seen Cognitive Linguistics (CL) emerge as an important, exciting and promising theoretical alternative to Chomskyan approaches to the study of language. Even so, sheer numbers and institutional inertia make it the case that most current neurolinguistic research either assumes that the Chomskyan formalist story is more or less correct (and thus that the task of neurolinguistics is to determine how the brain implements GB, for instance), or that the there are two possibilities, Chomskyanism or (...) associationism/connectionism, and that the task of neurolinguistics is to discover which is really the way the brain does it. In either case, the theoretical apparatus of CL is not being explored by neurolinguistics, and hence the promise CL holds for making genuine fruitful contact with theoretical neurobiology is not materializing as quickly as one might hope. This paper is an attempt to make some initial steps at fulfilling this promise. (shrink)
The emulation theory of representation articulated in the target article is further explained and explored in this response to commentaries. Major topics include: the irrelevance of equilibrium-point and related models of motor control to the theory; clarification of the particular sense of “representation” which the emulation theory of representation is an account of; the relation between the emulation framework and Kalman filtering; and addressing the empirical data considered to be in conflict with the emulation theory. In addition, I discuss the (...) further empirical support for the emulation theory provided by some commentators, as well as a number of suggested theoretical applications. (shrink)
Starting with Antonin Artaud's radio play To Have Done With The Judgement Of God, this article analyses the ways in which Artaud's idea of the body without organs links up with various of his writings on the body and bodily theatre and with Deleuze and Guattari's later development of his ideas. Using Klossowski (or Klossowski's Nietzsche) to explain how the dominance of dialogue equals the dominance of God, I go on to examine how the Son (the facialised body), the Father (...) (Language) and the Holy Spirit (Subjectification), need to be warded off in order to revitalize the body, reuniting it with ‘‘the earth’’ it has been separated from. Artaud's writings on Balinese dancing and the Tarahumaran people pave the way for the new body to appear. Reconstructing the body through bodily practices, through religion and above all through art, as Deleuze and Guattari suggest, we are introduced not only to new ways of thinking theatre and performance art, but to life itself.

Gareth Evans’ account of Identifi cation-freedom (IF), which he devel- ops in Chapters 6 and 7 of The Varieties of Reference (henceforth VR) is almost universally misunderstood.1 Howell is guilty of this same mis- understanding, and as a result claims to have mounted a criticism of Evans, when in fact he has not. I will take the occasion of Howell’s oth- erwise insightful article to clarify Evans’ position. Note that the bulk of Howell’s analysis is targeted at the phenomenon known (...) as immunity to error through misidentifi cation (IEM), which is related to but not (necessarily) identical to IF. Therefore, the accuracy of Howell’s treat- ment of Evans in particular is tangential to the main thrust of his article. My exegesis of Evans’ account — like any non-trivial exegesis — goes somewhat beyond anything Evans overtly says. That Evans did not ex- plicitly put the pieces together in the way I suggest they fi t no doubt contributes to the widespread misunderstanding of his views. But I am. (shrink)
We explored the influence of negation on cognitive dynamics, measured using mouse-movement trajectories, to test the classic notion that negation acts as an operator on linguistic processing. In three experiments, participants verified the truth or falsity of simple statements, and we tracked the computer-mouse trajectories of their responses. Sentences expressing these facts sometimes contained a negation. Such negated statements could be true (e.g., “elephants are not small”) or false (e.g., “elephants are not large”). In the first experiment, as predicted by (...) the classic notion of negation, we found that negation caused more discreteness in the mouse trajectory of a response. The second experiment induced a simple context for these statements, yet negation still increased discreteness in trajectories. A third experiment enhanced the pragmatic context of sentences, and the discreteness was substantially diminished, with one primary measure no longer significantly showing increased discreteness at all. Traditional linguistic theories predict rapid shifts in cognitive dynamics occur due to the nature of negation: It is an operator that reverses the truth or falsity of an interpretation. We argue that these results support both propositional and contextual accounts of negation present in the literature, suggesting that contextual factors are crucial for determining the kind of cognitive dynamics displayed. We conclude by drawing broader lessons about theories of cognition from the case of negation. (shrink)
In this reply we claim that, contra Dreyfus, the kinds of skillful performances Dreyfus discusses _are_ representational. We explain this proposal, and then defend it against an objection to the effect that the representational notion we invoke is a weak one countenancing only some global state of an organism as a representation. According to this objection, such a representation is not a robust, projectible property of an organism, and hence will gain no explana- tory leverage in cognitive scientific explanations. We (...) argue on conceptual and empirical grounds that the representations we have identified are not weak unprojectible global states of organisms, but instead genuinely explanatory representational parts of persons.

: Thoreau's journal contains a number of passages which explore the nature of perception, developing a response to skeptical doubt. The world outside the human mind is real, and there is nothing illusory about its perceived beauty and meaning. In this essay, I draw upon the work of Stanley Cavell (among others) in order to frame Thoreau's reflections within the context of the skeptical questions he seeks to address. Value is not a subjective projection, but it also cannot be perceived (...) without the appropriate kind of emotional orientation or attunement toward the world: that is, an attitude of trust or acceptance. Without this affective receptivity, or "perceptual faith," our knowledge of reality is limited. The beliefs we hold onto in the face of objective uncertainty establish the framework within which we make particular evaluations, and in this sense they are a necessary condition of practical reason. Every understanding has its mood. (shrink)
Each of us distinguishes between himself and states of himself on the one hand, and what is not himself or a state of himself on the other. What are the conditions of our making this distinction, and how are they fulfilled? In what way do we make it, and why do we make it in the way we do?
It is an under-appreciated fact that we have no significant understanding of the neurobiological mechanisms supporting any aspect of cognition, broadly construed. The limited understanding we do have is a combination of a multitude of enticing empirical fragments, scattered sparsely on a background of noise, and a number of vastly underdetermined theoretical frameworks. But however incomplete the answers, the questions posed by cognitive neuroscience are compelling. Indeed, it is nothing less than ourselves -- our decision making abilities, our command of (...) language, our own consciousness -- that we are seeking to understand. (shrink)
It is the aim of work in theoretical cognitive science to produce good theories of what exactly cognition amounts to, preferably theories which not only provide a framework for fruitful empirical investigation, but which also shed light on cognitive activity itself, which help us to understand our place, as cognitive agents, in a complex causally determined physical universe. The most recent such framework to gain significant fame is the so-called dynamical approach to cognition (henceforth DST, for Dynamical Systems Theory ). (...) Explaining and exploring DST is the purpose of the collection Mind as Motion: Explorations in the Dynamics of Cognition , edited by Robert Port and Timothy van Gelder. (shrink)
The concept of pluralism in corporate governance is stated as an emergent theory. Grounded in the concept of enhancing the input of various stakeholders and lessening the control of managers in corporate governance, the theory is the foundation of proposed legal changes in corporate governance and the board of directors. While more pluralistic control has been conceptually linked to improved social performance of the firm, this proposition is not supported in an empirical investigation.
Discussions of the concept of authenticity often fail to define the conditions of an appropriate emotional orientation toward the world. With a more solid philosophical understanding of emotion, it should be possible to define more precisely the necessary conditions of emotional authenticity. Against this background, I interpret Kierkegaard’s Either/Or as a narrative text that suggests a moral psychology of emotion that points toward the development of a better way of thinking about the ethics of authenticity. In the process, I also (...) engage with the positions of other philosophers, both “existential” and “analytic.” The upshot of my argument is that a cognitive phenomenology of emotion can flesh out the ideal of truthfulness as a virtue of character, while forcing moral philosophers to question whether authenticity should be understood as an achievement of the will rather than as a matter of affective receptivity.

Environmental philosophers often conflate the concepts of intrinsic value and moral standing. As a result, individualists needlessly deny intrinsic value to species, while holists falsely attribute moral standing to species. Conceived either as classes or as historical individuals, at least some species possess intrinsic value. Nevertheless, even if a species has interests or a good of its own, it cannot have moral standing because species lack sentience. Although there is a basis for duties toward some species (in terms of their (...) intrinsic value), it is not the one that the holists claim. (shrink)

Cross-cultural interviewing can pose challenges for journalists, given potential differences in language, word choice, volume, body posture, and group dynamics. This article explores some of the complexities of cross-cultural interviews with the dual aim of heightening awareness of ethical considerations for journalists who conduct them and of discussing ethical principles that may help in guiding their work. This article attempts to move the discussion of cross-cultural interviews beyond traditional Western ethics. Eastern moral philosophy and ideals of trust and human relations (...) similar to, but predating the work of contemporary Western communitarians are considered. The authors' ethnographic study of MLB's “Nippon Summer”—the influx of Japanese players in 2007—and analysis of articles resulting from press coverage of those players serve as a framework for discussing ethical considerations at play in cross-cultural journalism, when, for example, West writes East.

The question of whether time is its own best representation is explored. Though there is theoretical debate between proponents of internal models and embedded cognition proponents (e.g. Brooks R 1991 Artificial Intelligence 47 139–59) concerning whether the world is its own best model, proponents of internal models are often content to let time be its own best representation. This happens via the time update of the model that simply allows the model’s state to evolve along with the state of the (...) modeled domain. I argue that this is neither necessary nor advisable. I show that this is not necessary by describing how internal modeling approaches can be generalized to schemes that explicitly represent time by maintaining trajectory estimates rather than state estimates. Though there are a variety of ways this could be done, I illustrate the proposal with a scheme that combines filtering, smoothing and prediction to maintain an estimate of the modeled domain’s trajectory over time. I show that letting time be its own representation is not advisable by showing how trajectory estimation schemes can provide accounts of temporal illusions, such as apparent motion, that pose serious difficulties for any scheme that lets time be its own representation.
