This paper addresses the relationship between psychological capacities, as they are understood within cognitive psychology, and neurobiological activities. First, Lycan’s (1987) account of this relationship is examined and certain problems with his account are explained. According to Lycan, psychological capacities occupy a higher level than neurobiological activities in a hierarchy of levels of nature, and psychological entities can be decomposed into neurobiological entities. After discussing some problems with Lycan’s account, a similar, more recent account built around levels of mechanisms is (...) examined (Craver 2007). In the second half of this paper, an alternative is laid out. This new account uses levels of organization and levels of explanation to create a two-dimensional model. Psychological capacities occupy a high level of explanation relative to the cellular and molecular levels of organization. As a result, according to this model, psychological capacities are a particular way of describing the activities that occur at the cellular and molecular levels of organization. (shrink)

People often sincerely assert or judge one thing (for example, that all the races are intellectually equal) while at the same time being disposed to act in a way evidently quite contrary to the espoused attitude (for example, in a way that seems to suggest an implicit assumption of the intellectual superiority of their own race). Such cases should be regarded as ‘in-between’ cases of believing, in which it's neither quite right to ascribe the belief in question nor quite right (...) to say that the person lacks the belief.

Thought experimental methods play a central role in empirical moral psychology. Against the increasingly common interpretation of recent experimental data, I argue that such methods cannot demonstrate that moral intuitions are produced by reflexive computations that are implicit, fast, and largely automatic. I demonstrate, in contrast, that evaluating thought experiments occurs at a near-glacial pace relative to the speed at which reflexive information processing occurs in a human brain. So, these methods allow for more reflective and deliberative processing than has (...) commonly been assumed. However, these methods may still provide insight into some human strategies for navigating unfamiliar moral dilemmas. (shrink)

Some philosophers have conflated functionalism and computationalism. I reconstruct how this came about and uncover two assumptions that made the conflation possible. They are the assumptions that (i) psychological functional analyses are computational descriptions and (ii) everything may be described as performing computations. I argue that, if we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions.

This paper proposes that pictures are functional objects which figure in norm‐governed practices of usage yet whose specific function is to present the world as it looks to acculturated perceivers. Pictorial content presents the way the world looks to a subject's acculturated perceptual grasp. Hence, pictorial content needs to be explained in terms of a theory of perceptual content, but a novel theory which departs from the two‐stage sensation‐based approach to perception and the polarization between naturalism and conventionalism that it (...) engenders. Following a diagnosis of this polarization, I invoke a novel theory of perception that explains perceptual content as conceptually articulated and determinate in character. I show that (1) pictures present content of the same distinctive determinate type as perceptual content; and that (2) pictures do so by invoking perceptual experience and perceptual processes that are of the same kind as those invoked by actual scenes. This perceptualist approach considers and explains the role of norms as well as of the nature of our visual processes, allowing us to allocate the insights of both conventionalism and naturalism to their proper theoretical roles.

Belief is not a unified phenomenon. In this paper I argue, as a number of other riters argue, that one should distinguish a variety of belief-like attitudes: believing proper - a dispositional state which can have degrees - holding true - which can occur without understanding what one believes - and accepting - a practical and contextual attitude that has a role in deliberation and in practical reasoning. Acceptance itself is not a unified attitude. I explore the various relationships and (...) differences between these doxastic attitudes, and claim that although acceptance is distinct from belief, it rests upon it, and is therefore a species of belief.

The differences Block attempts to capture with his putative distinction between P-consciousness and A-consciousness are more directly and perspicuously handled in terms of differences in richness of content and degree of influence. Block's critiques, based on his misbegotten distinction, evaporate on closer inspection.

A new position in the philosophy of mind has recently appeared: the extended mind hypothesis (EMH). Some of its proponents think the EMH, which says that a subject's mental states can extend into the local environment, shows that internalism is false. I argue that this is wrong. The EMH does not refute internalism; in fact, it necessarily does not do so. The popular assumption that the EMH spells trouble for internalists is premised on a bad characterization of the internalist thesis—albeit (...) one that most internalists have adhered to. I show that internalism is entirely compatible with the EMH. This view should prompt us to reconsider the characterization of internalism, and in conclusion I make some brief remarks about how that project might proceed. (shrink)

In the wake of Frege's attack on psychologism and the subsequent influence of Logical Positivism, psychological considerations in philosophy came to be viewed with suspicion. Philosophical questions, especially epistemological ones, were viewed as 'logical' questions, and logic was sharply separated from psychology. Various efforts have been made of late to reconnect epistemology with psychology. But there is little agreement about how such connections should be made, and doubts about the place of psychology within epistemology are still much in evidence. It (...) therefore remains to be clarified just how such links should be established, and what impact they would have on the direction of epistemology. (shrink)

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here’s a skeptical hypothesis; you can’t epistemically neutralize (...) it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific-philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic’s argument goes through even if we adopt the clever anti-skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts. (shrink)

There are two interrelated but distinct programs which go by the name evolutionary epistemology. One attempts to account for the characteristics of cognitive mechanisms in animals and humans by a straightforward extension of the biological theory of evolution to those aspects or traits of animals which are the biological substrates of cognitive activity, e.g., their brains, sensory systems, motor systems, etc. (EEM program). The other program attempts to account for the evaluation of ideas, scientific theories and culture in general by (...) using models and metaphors drawn from evolutionary biology (EET program). The paper begins by distinguishing the two programs and discussing the relationship between them. The next section addresses the metaphorical and analogical relationship between evolutionary epistemology and evolutionary biology. Section IV treats the question of the locus of the epistemological problem in the light of an evolutionary analysis. The key questions here involve the relationship between evolutionary epistemology and traditional epistemology and the legitimacy of evolutionary epistemology as epistemology. Section V examines the underlying ontological presuppositions and implications of evolutionary epistemology. Finally, section VI, which is merely the sketch of a problem, addresses the parallel between evolutionary epistemology and evolutionary ethics. (shrink)

Marshall's article used Wittgenstein to argue that self functions as an explanation for a name rather than a referent. This brief response tries to rescue Marshall from an apparent reduction of self to material body without returning him to the mind/body dualism that he, with Wittgenstein and Dennett, seeks to avoid. It treats ‘I’ as an emergent institutional fact, not inconsistent with a constructed explanation or narrative, but emerging from shared social practices rather than an abstracted agent.

Famed so-called 'Frankfurt-type examples' have been invoked to cast doubt on the principle that a person is morally responsible for what she has done only if she could have done otherwise. Many who disagree that the examples are successful in this respect argue that these examples succumb to a deadly dilemma. I uncover and assess libertarian assumptions upon which the 'dilemma objection' is based. On exposing these assumptions, it becomes clear that various sorts of libertarian are no longer entitled to (...) one or the other horns of the dilemma. (shrink)

It has been commonplace in epistemology since its inception to idealize away from computational resource constraints, i.e., from the constraints of time and memory. One thought is that a kind of ideal rationality can be specified that ignores the constraints imposed by limited time and memory, and that actual cognitive performance can be seen as an interaction between the norms of ideal rationality and the practicalities of time and memory limitations. But a cornerstone of naturalistic epistemology is that normative assessment (...) is constrained by capacities: you cannot require someone to do something they cannot or, as it is usually put, ought implies can. This much we take to be uncontroversial. We argue that differences in architectures, goals and resources imply substantial differences in capacity, and that some of these differences are ineliminable. It follows that some differences in goals and architectural and computational resources matter at the normative level: they constrain what principles of normative epistemology can be used to describe and prescribe their behavior. As a result, we can expect there to be important epistemic differences between the way brains, individuals, and science work. (shrink)

Constructivism undermines realism by arguing that experience is mediated by concepts, and that there is no direct way to examine those aspects of objects that belong to them independently of our conceptualizations; perception is theory-laden. To defend realism one has to show first that perception relates us directly with the world without any intermediary conceptual framework. The result of this direct link is the nonconceptual content of experience. Second, one has to show that part of the nonconceptual content extracted from (...) the environment correctly represents features of mind independent objects. With regard to the first condition, I have argued elsewhere that a part of visual processing, which I call “perception,” is theory-neutral and nonconceptual. In this paper, facing the second demand, I argue that a part of the nonconceptual content of perception presents properties that are the properties of mind independent objects. I claim first that nonconceptual content is the appropriate level of analysis of the issue of realism since it avoids the main problems besetting various types of analysis of the issue at the level of beliefs about the world. Then I claim that a subset of the nonconceptual content presents features of objects in the environment as they really are. (shrink)

In this paper, I argue that a satisfactory account of consciousness will involve both (1) local indeterminism, in that some relevant events are not wholly and unequivocally pre‐determined by immediately prior local events, and (2) nonlocality, in that, within the leeways left by local indeterminism, what happens can be immediately affected by spatially separated or extended events. I briefly consider if this can be avoided by treating consciousness as supervenient and epiphenomenal; and I suggest that current theories of consciousness break (...) down through failure to incorporate local indeterminism and nonlocality. I conclude by outlining possible implications for freedom of the will, physicalism, and the relevance of quantum mechanics to consciousness. (shrink)

Abstract The language of consciousness and that of brain function seem vastly different and incommensurable ways of approaching human mental life. If we look at what we mean by consciousness we find that it has a great deal to do with the sensitivity and responsiveness shown by a subject toward things that happen. Philosophically, we can understnd ascriptions of consciousness best by looking at the conditions which make it true for thinkers who share the concept to say that one of (...) them is conscious. This depends on consciousness being manifest. When we also note that manifest, flexible and exploratory responses to one's environment are the basis of concept use, an a priori link between concepts and consciousness is forged. The brain structures subserving such responses are complex but crucially involve the multi?tracked and cross?linked information processing to be found in the neocortex. This function draws on the motivational and orienting activity arising in lower brain systems but orchestrates that into an articulated structure of behaviour control. The conclusion is that human consciousness is an umbrella term for complex and animated mental activity which makes extensive use of many different perceptual systems and also of the social milieu within which human cognition develops.

This paper attempts in the first instance to clarify the application of the personal/sub-personal distinction to psychoanalysis and to indicate how this issue is related to that of psychoanalysis" epistemology. It is argued that psychoanalysis may be regarded either as a form of personal psychology, or as a form of jointly personal and sub-personal psychology, but not as a form of sub-personal psychology. It is further argued that psychoanalysis indicates a problem with the personal/sub-personal distinction itself as understood by Dennett (...) A revised view of the distinction, which is argued to reflect its true metaphysical significance, is proposed. (shrink)

In this paper I argue that neuroscience has been harmed by the widespread adoption of seriously inadequate methodologies or philosophies of science - most notably inductivism and falsificationism. I argue that neuroscience, in seeking to understand the human brain and mind, needs to follow in the footsteps of evolution.

According to the rationality thesis , the possession of propositional attitudes is inextricably tied to rationality. How in this context should we conceive of rationality? In one sense, being rational is contrasted with being non-rational, as when human beings are described as rational animals. In another sense, being rational is contrasted with being irrational. I shall call rationality in this latter sense evaluative rationality . Whatever else it might involve, evaluative rationality surely has to do with satisfying requirements of rationality (...) such as, presumably, the following: That one avoid inconsistency in beliefs. That one not adopt new beliefs unless what one knows entails or is evidence for the truth of those beliefs. That one not have φing as a goal yet do nothing necessary for one to φ. (shrink)

1. When we attribute beliefs, desires, and other states of common sense psychology to a person, or for that matter to an animal or an artifact, we are assuming or presupposing that the person or object can be treated as an intentional system. 2. An intentional system is one which is rational through and through; its beliefs are those it ought to have, given its perceptual capacities, its epistemic needs, and its biography…. Its desires are those it ought to have, (...) given its biological needs and the most practicable means of satisfying them…. And its behavior will consist of those acts that it would be rational for an agent with those beliefs and desires to perform. [beliefs + desires  action] 3. If rationality is absent, we cannot coherently ascribe beliefs at all. 4. Therefore, no experiment could demonstrate that people systematically invoke invalid or irrational inferential strategies.

One holistic thesis about symbols is that a symbol cannot exist singly, but only as apart of a symbol system. There is also the plausible view that symbol systems emerge gradually in an individual, in a group, and in a species. The problem is that symbol holism makes it hard to see how a symbol system can emerge gradually, at least if we are considering the emergence of a first symbol system. The only way it seems possible is if being (...) a symbol can be a matter of degree, which is initially problematic. This article explains how being a cognitive symbol can be a matter of degree after all. The contrary intuition arises from the way a process of interpretation forces an all-or-nothing character on symbols, leaving room for underlying material to realize symbols to different degrees in a way that Daniel Dennett’s work can help illuminate. Holism applies to symbols as interpreted, while gradualism applies to how the underlying material realizes symbols.Selon une thèse holistique sur les symboles, un symbole ne peut exister isolément mais doit faire partie d’un systéme symbolique. Une opinion, elle aussi plausible, veut que les systèmes symboliques émergent graduellement chez un individu, un groupe ou une espèce. Le problème c’est qu’on voit mal, si le holisme des systèmes symboliques tient, comment un système symbolique peut émerger graduellement, du moins pour la première fois. Ce n’est possible, semble-t-il, que si être un symbole est affaire de degré, thèse au départ problématique. Cet article explique comment être un symbole cognitif peut après tout être affaire de degré. L’intuition contraire vient de ce que le processus d’interprétation nous force au tout ou rien, ce qui laisse un jeu dans la façon dont le matériel sous-jacent réalise les symboles à des degrés divers. Les travaux de Daniel Dennett sont à cet égard éclairants. Le holisme vaut pour les symboles tels qu’ils sont interprétés, tandis que le gradualisme vaut pour la façon dont le matériel sous-jacent réalise les symboles. (shrink)

Key elements of Randolph Clarke's libertarian account of freedom that requires both agent-causation and non-deterministic event-causation in the production of free action is assessed with an eye toward determining whether agent-causal accounts can accommodate the truth of judgments of moral obligation.

In this paper I discuss Searle's claim that the computational properties of a system could never cause a system to be conscious. In the first section of the paper I argue that Searle is correct that, even if a system both behaves in a way that is characteristic of conscious agents (like ourselves) and has a computational structure similar to those agents, one cannot be certain that that system is conscious. On the other hand, I suggest that Searle's intuition that (...) it is “empirically absurd” that such a system could be conscious is unfounded. In the second section I show that Searle's attempt to show that a system's computational states could not possibly cause it to be conscious is based upon an erroneous distinction between computational and physical properties. On the basis of these two arguments, I conclude that, supposing that the behavior of conscious agents can be explained in terms of their computational properties, we have good reason to suppose that a system having computational properties similar to such agents is also conscious.

I argue that natural realism is the best approach to explaining some emotional actions, and thus is the best candidate to explain the relevant emotions. I take natural realism to be the view that these emotions are motivational states which must be identified by using (not necessarily exclusively) naturalistic discourse which, if not wholly lacking intentional terms, at least does not require reference to belief and desire. The kinds of emotional actions I consider are ones which continue beyond the satisfaction (...) of the desires that could plausibly be said to motivate the agent. As a contrast to a realist position about emotions I examine interpretationist theories of mind, using Dennett and Davidson as examples, and show that the emotional actions in question will fail to be explained by these theories. In conclusion, I provide one weak version of a natural realist view of emotions, and show how it succeeds where interpretationism fails. (shrink)

The liking of a sensation, e.g., a taste, is a conscious occurrent but does not consist in having the liked sensation accompanied by a "pleasure sensation" - for there is no such sensation. Several alternative accounts of liking, including Aydede's "feeling episode" theory and Schroeder's representationalist theory are considered. The proposal that liking a sensation is having the non-sensory experience of liking directed upon it is explained and defended. The pleasure provided by thoughts, conversations, walks, etc., is analyzed and brought (...) into relation to the account of liking one's sensations. (shrink)

Functionalism in the philosophy of mind is here criticized from the perspective of a more naturalistic and less compromising form of materialism. Parallels are explored between the problem of cognitive activity and the somewhat more settled problem of vital activity. The lessons drawn suggest that functionalism in the philosophy of mind may be both counterproductive as a research strategy, and false as a substantive position.

Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This view stands in sharp contrast to the to visual perception and cognition, whose most prominent proponent has been J.J. Gibson. In the direct theory, perception does not involve computations of any sort; it is the result of the direct pickup of available information. The publication of Gibson's recent book (Gibson 1979) offers an opportunity to examine his approach, and, more generally, to contrast (...) the theory of direct perception with the computational/representational view. In the first part of the present article (Sections 2direct perceptioncase study”: the problem of perceiving the three-dimensional shape of moving objects is examined. This problem, which has been extensively studied within the immediate perception framework, serves to illustrate some of the inherent shortcomings of that approach. Finally, in Section 5, an attempt is made to place the theory of direct perception in perspective by embedding it in a more comprehensive framework. (shrink)

The problem of semantic content is the problem of explicating those features of brain processes by virtue of which they may properly be thought to possess meaning or reference. This paper criticizes the account of semantic content associated with fodor's version of cognitive science, And offers an alternative account based on mathematical communication theory. Its key concept is that of a neuronal representation maintaining a high-Level of mutual information with a designated external state of affairs under changing conditions of perceptual (...) presentation.

Incompatibilism is the view that privileged knowledge of our own mental states cannot be reconciled with externalism regarding the content of mental states. Davidson has recently developed two arguments that are supposed to disprove incompatibilism and establish the consistency of privileged access and externalism. One argument criticizes incompatibilism for assuming that externalism conflicts with the mind‐body identity theory. Since mental states supervene on neurological events, Davidson argues, they are partly ‘in the head’ and are knowable just by reflection. Another argument (...) rejects incompatibilism by repudiating the object perception model of introspection. Once extemalism is freed from the internalist idea that thoughts take objects which are inner epistemological intermediaries, Davidson maintains, it poses no threat to privileged self‐knowledge. It is argued that neither of these arguments is successful, since both disprove assumptions irrelevant to incompatibilism. Moreover, it is indicated how Davidson would have to go about defending his positive account of privileged self‐knowledge against the principal incompatibilist arguments. (shrink)

It is sometimes said that humans are unlike other animals in at least one crucial respect. We do not simply form beliefs, desires and other mental states, but are capable of caring about our mental states in a distinctive way. We can care about the justification of our beliefs, and about the desirability of our desires. This kind of observation is usually made in discussions of free will and moral responsibility. But it has profound consequences, or so I shall argue, (...) for our conception of the very nature of beliefs and other mental states. Suitably developed, it allows us to draw a line between two distinct ways in which a creature may possess a belief, represent a scene, and fall into error. The first way (which I shall call the 'mindless' way) involves little more than an encoding of information in some way designed to guide appropriate response. This is the common heritage of humans, and many other animals. The second way (which I shall call the 'mindful' way) requires that the creature be capable in addition of a special kind of second-order reflection, and (importantly) be expert at detecting the kinds of situation in which such reflection is called for. The differences between these two ways of 'believing that P' are sufficiently deep and significant to warrant (or so I claim) our treating them as two distinct classes of mental states. For it is only courtesy of the second layer of complexity, I shall argue, that it becomes proper to hold someone accountable for their beliefs or other mental states, and it is this fact of (something like) accountability that in turn raises the most significant challenge for philosophical attempts to give naturalized accounts of meaning, belief, and mentality.

This paper sets out the case for a two-level theory of human psychology. It takes its start from Daniel Dennett.

The contention that cognitive psychology and radical behaviorism yield equivalent accounts of decision making and problem solving is examined by contrasting a framework of cognitive interpretation, Dennett's intentional stance, with a corresponding interpretive stance derived from contextualism. The insistence of radical behaviorists that private events such as thoughts and feelings belong in a science of human behavior is indicted in view of their failure to provide a credible interpretation of complex human behavior. Dennett's interpretation of intentional systems is an exemplar (...) of the interpretive stance radical behaviorism requires; a corresponding interpretive position can be based initially on a radical behaviorist view of human behavior and its determinants. This "contextual stance" is ontologically and methodologically distinct from the intentional stance over the range of explanations for which scientific psychology, cognitive or behaviorist, is responsible.

Abstract The paper considers two recent accounts of the difference between human and animal thought. One deflationary account, due to Daniel Dennett, insists that the only real difference lies in our ability to use words and sentences to give artificial precision and determinacy to our mental contents. The other, due to Paul Smolensky, conjectures that we at times deploy a special purpose device (the Conscious Rule Interpreter) whose task is to deal with public, symbolically coded data and commands. Both these (...) accounts make a crucial error. They offer what is in effect an extra top?level processor to soothe our realist/classical prejudices. But in each case the extra ingredient turns out to be explanatorily hollow. Appealing to language use and language processing alone mistakes a cognitive effect for a cognitive cause. I argue instead that we need to seek a more profound architectural condition which may ground our conscious linguistic abilities but also explains a variety of deeper facts. I sketch a picture which seems to meet those needs and draw out its implications for the debates about belief and about classical Artificial Intelligence. (shrink)

Although they may differ on the reason why, many philosophers hold that it is a priori that an object is red if and only if it is such as to look red to normal observers in normal conditions.

In this paper I distinguish three alternatives to the functionalist account of qualitative states such as pain. The physicalist-functionalist holds that (1) there could be subjects functionally equivalent to us whose mental states differed in their qualitative character from ours, (2) there could be subjects functionally equivalent to us whose mental states lacked qualitative character altogether and (3) there could not be subjects like us in all objective respects whose qualitative states differed from ours. The physicalist-functionalist holds (1) and (3) (...) but denies (2). The transcendentalist holds (1) and (2) and denies (3). I argue that both versions of physicalist-functionalism inherit the problem of property dualism which originally helped to motivate functionalist theories of mind. I also argue that neither version of physicalist-functionalism can distinguish in a principled way between those neurophysiological properties of a subject which are relevant to the qualitative character of that subject's mental states and those which are not. I conclude that the only alternative to a functionalist account of qualitative states is a transcendentalist account and that this alternative is not likely to appeal to the critics of functionalism. (shrink)

I argue that Daniel Dennett's latest book, Consciousness Explained, presents a radically eliminativist view of conscious experience in which experience or, in Dennett's own words, actual phenomenology, becomes a merely intentional object of our own and others? judgments ?about? experience. This strategy of ?intentionalizing? consciousness dovetails nicely with Dennett's background model of brain function: cognitive pandemonium, but does not follow from it. Thus Dennett is driven to a series of independent attacks on the notion of conscious experience, many of which (...) depend upon verificationist premises. I do not directly dispute the appeal to verificationism (though many would, I am sure) but rather aim to show that the sort of verificationist arguments that Dennett employs are fundamentally similar to classical sceptical arguments. The philosophical status of such arguments remains perennially unclear, but none of them produce conviction in their ostensible conclusions. I argue that Dennett's verificationist strategy suffers the same fate. (shrink)

Nietzsche's writing style is designed to elicit affective responses in his readers. Humour is one of the most common means by which he attempts to engage his readers' affects. In this article, I explain how and why Nietzsche uses humour to achieve his philosophical ends. The article has three parts. In part 1, I reject interpretations of Nietzsche's humour on which he engages in self‐parody in order to mitigate the charge of decadence or dogmatism by undermining his own philosophical authority. (...) In part 2, I look at how Nietzsche uses humour and laughter as a critical tool in his polemic against traditional morality. I argue that one important way in which Nietzsche uses humour is as a vehicle for enhancing the effectiveness of his ad hominem arguments. In part 3, I show how Nietzsche exploits humour's social dimension in order to find and cultivate what he sees as the right kinds of readers for his works. (shrink)

In recent years, the ‘mechanistic view’ has developed as a popular alternative to the ‘semantic view’ concerning the identity of physical computation. However, semanticists have provided powerful arguments that suggest the mechanistic view fails to deliver essential distinctions between paradigmatic computational operations. This article reviews responses on behalf of the mechanist and uses this opportunity to propose a type of pluralism about computational identity. This pluralism contends that there are multiple ‘levels’ of properties and relations pertaining to computation that can (...) inform different kinds of individuation. As such, for the pluralist, there are multiple legitimate ways of classifying computation, depending on the nature of the system in question, and one’s own epistemic priorities. (shrink)
