Radical enactive and embodied approaches to cognitive science oppose the received view in the sciences of the mind in denying that cognition fundamentally involves contentful mental representation. This paper argues that the fate of representationalism in cognitive science matters significantly to how best to understand the extent of cognition. It seeks to establish that any move away from representationalism toward pure, empirical functionalism fails to provide a substantive “mark of the cognitive” and is bereft of other adequate means for (...) individuating cognitive activity. It also argues that giving proper attention to the way the folk use their psychological concepts requires questioning the legitimacy of commonsense functionalism. In place of extended functionalism—empirical or commonsensical—we promote the fortunes of extensive enactivism, clarifying in which ways it is distinct from notions of extended mind and distributed cognition.

This paper will defend the claim that, under certain circumstances, the material vehicles responsible for an agent’s conscious experience can be partly constituted by processes outside the agent’s body. In other words, the consciousness of the agent can extend. This claim will be supported by the Extended Mind Thesis (EMT) example of the artist and their sketchpad (Clark 2001, 2003). It will be argued that if this example is one of EMT, then this example also supports an argument for (...) consciousness extension. Clark (2009) rejects claims of consciousness extension. This paper will challenge Clark and argue that he fails to show that the material vehicles responsible for consciousness must be internal to the agent. (shrink)

In trying to characterize the relationship between psychology and neuroscience, the trend has been to argue that reductionism does not work without suggesting a suitable substitute. I offer explanatory extension as a good model for elucidating the complex relationship among disciplines which are obviously connected but which do not share pragmatic explanatory features. Explanatory extension rests on the idea that one field can "illuminate" issues that were incompletely treated in another. In this paper, I explain how this "illumination" (...) would work between psychology and neuroscience. (shrink)

Extension of the system that includes the key substrates for sensation, perception, emotion, volition, and cognition, and all representational sources for cognition, supports the view that there is an extended mind and an extended body. These intellectual views can be made practical in a humanist system based on extensions and in religious systems based on extensions. Independently, there is also an institutional extension of secularism. Hence, I maintain, there are five principal forms of extension.

For well over two decades, Andy Clark has been gleaning theoretical lessons from the leading edge of cognitive science, applying a combination of empirical savvy and philosophical instinct that few can match. Clark’s most recent book, Supersizing the Mind: Embodiment, Action, and Cognitive Extension, brilliantly expands his oeuvre. It offers a well-informed and focused survey of research in the burgeoning field of situated cognition, a field that emphasizes the contribution of environmental and non-neural bodily structures to the production (...) of intelligent behavior. The situated research program, fledgling though it may be in some respects, has reached an age at which its philosophical stock can reasonably be taken; and Clark is just the person to take it. Supersizing the Mind consists of three main divisions. The first develops the case for the distinctively extended view of cognition, according to which the human mind or cognitive system literally comprises elements beyond the boundary of the human organism. The second responds to critics of the extended outlook: Frederick Adams, Kenneth Aizawa, Keith Butler, Brie Gertler, Rick Grush, and me, among others. The third major division evaluates nonextended strands in the situated program, in particular, those that emphasize the role of the non-neural body in cognition. (shrink)

Abstract Objections to life extension often focus on its effects for individual well-being. Prominent amongst these concerns is the possibility that life extending technologies will extend lifespan without preventing the ageing of the mind. Writers on the subject express the fear that life extending drugs will keep us physically youthful whilst our minds decay, succumbing to dementia, boredom, and loneliness. Generally these fears remain speculative, in part due to the absence of genuine life extending technologies. In this paper, (...) however, I examine the implications of an existing life extension technology. Caloric restriction (CR) and drugs that mimic its effects, such as rapamycin, metformin and resveratrol have been shown to increase average and maximum lifespan in a wide variety of organisms, and seem likely to do so in humans. Moreover, some CR mimetic drugs (CRMs) are already widely used. This means that they present a pressing test case for fears about mental ageing in an extended life. Misgivings about mental ageing can be divided into biomedical factors such as the likelihood of brain ageing, and psychological factors such as loss of meaning and boredom. I argue that studies of CR suggest that brain ageing will be beneficially slowed. However, it is less clear that deleterious aspects of psychological ageing can be similarly retarded. I argue that this reduces the desirability of life extension unless major social changes can be made. (shrink)

Paul Pietroski develops an iconoclastic account of linguistic meaning. Here, I invite him to say more about what it implies about the relations between language, truth, and conceptual content. Readers concerned with securing the objectivity of conceptual thought may be worried about his claims that typical concepts “have no extensions” and that they “fit one another better than they fit the world.” Others might applaud his anti‐extensionalism in natural‐language semantics but fear that his account re‐raises familiar problems about extensions at (...) the level of psychology.

In 1998, Clark and Chalmers articulated and defended the extended mind hypothesis. They argued, against the backdrop of functionalism about the mind, and for the specific case of the mental state type belief, that it is possible for a person's mind to extend out-side the boundary of their body. Departing from the framework of Indo-analytic comparative philosophy, we show that the Advaita Vedanta School of classical Indian philosophy, against the backdrop of a specific form of panpsychism, defended (...) an account on which a person's conscious experience, during an act of perceptual knowledge, is located outside the boundary of their body. Using the work of Adams and Maher on how to respond to Adams and Aizawa's coupling-constitution fallacy, we argue that the Advaita Vedanta account of mind can be taken to generate what we call the mind extension hypothesis -- the view that consciousness can extend outside of the body in perception. Recognizing the problematic nature of panpsychism as a metaphysical view about consciousness, we close by following work by Itay Shani on the real combination problem. We argue that the Advaita Vedanta account of panpsychism, as a kind of cosmopsychism, allows for a response to the so-called real combination problem proposed by Coleman. (shrink)

Optimising the 4E revolution in cognitive science arguably requires the rejection of two guiding commitments made by orthodox thinking in the field, namely that the material realisers of cognitive states and processes are located entirely inside the head, and that intelligent thought and action are to be explained in terms of the building and manipulation of content-bearing representations. In other words, the full-strength 4E revolution would be secured only by a position that delivered externalism plus antirepresentationalism. I argue that one (...) view in 4E space—extended functionalism—is appropriately poised to deliver externalism but not antirepresentationalism. By contrast, in the case of a competing 4E view—radical enactivism—even if that view can deliver antirepresentationalism, its pivotal notion of extensiveness falls short of establishing externalism. These conclusions are justified via an examination of, and by responding critically to, certain key arguments offered in support of their view by the radical enactivists. (shrink)

The specious present (James, 1890/1950) is the phenomenal temporal structure of the representational content of my present experience. This article is a study of the mereological structure of the specious present and what it reveals about the nature of the mind. I argue that the specious present has certain features that cannot be easily explained within the framework of physicalism about the mind — the view that consciousness is nothing over and above what is physical. In particular, the (...) specious present is a phenomenally extended (i.e.non-instantaneous) whole whose parts are conceptual abstractions and are therefore dependent on this whole. However, unlike the specious present, what is physical does not have this special property of the parts being dependent on the whole. Therefore, it is unclear how the specious present can be explained in physicalistic terms. (shrink)

Currently, humanity is experiencing an explosive growth in technological objects designed to improve the body and mind. The main objective of this article is to review two recent classificatory and explanatory systems to cognitive enhancement cybernetic technologies, including both wearable and implantable artifacts that reorganize human embodiment or extend the mind. I argue that an outdated model of the cognitive sciences serves as the basis for these revised systems and taxonomies. Taking an embodied approach to the cognitive sciences, (...) I propose an alternative focus to classify cognitive enhancement cybernetic technologies. Specifically, by adopting a non-orthodox enactive approach to embodied cognition, I propose a new classificatory system that redefines the notion of the cybernetically enhanced human, restricting it to a purely cognitive context. Finally, I evaluate some philosophical implications of my system. (shrink)

I argue that the Conceptual Ethics and Conceptual Engineering framework, in its pragmatist version as recently defended by Thomasson (2017, 2020), provides a means of articulating and defending the conventionalist interpretation of projects of conceptual extension (e.g. the extended mind, the extended phenotype) in biology and psychology. This promises to be illuminating in both directions: it helps to make sense of, and provides an explicit methodology for, pragmatic conceptual extension in science, while offering further evidence for the (...) value and fruitfulness of the conceptual ethics/engineering framework itself, in particular with respect to conceptual change within science, which has thus-far received little attention in the literature on conceptual ethics/engineering.

This paper examines and reflects on Princess Elisabeth’s of Bohemia exchange with Descartes concerning the notorious difficulties of his doctrine of human nature as a union of two independent and mutually exclusive substances mind and body. The aim is to situate her questions in the context of the debate Descartes’s doctrine spurred among his contemporaries and to show the philosophical interest of her own contribution to the understanding of and clarification of the issues confronting Descartes.

- Emilie du Châtelet offers an interesting and unusual account of the origin of our representation of extension. - She is an idealist about the essence extension, bodies and space, regarding them as mental constructs. - Du Châtelet's account requires a brute fact about the mind, in apparent tension with the Principle of Sufficient Reason.

This paper explores the ontology of Malebranche's notion of "intelligible extension", the archetypal divine idea of matter which he believed to be the immediate object of our own minds in all of our thoughts about corporeal things. Building on this account of its ontology, and through an examination of a form of isomorphism between intelligible extension and the created spatial world, the paper also attempts to explain the manner in which it could fulfill its epistemological role of representing (...) all possible bodies and supplying us with our abstract knowledge of geometry.

The multicultural experience offers the intriguing possibility for an empirical examination of how free-energy principles explain dynamic cultural behaviors and pragmatic cultural phenomena and a challenging but decisive test of thinking through other minds predictions. We highlight that TTOM needs to treat individuals as active cultural agents instead of passive learners.

Although the notion of logical object plays a key role in Frege's foundational project, it has hardly been analyzed in depth so far. I argue that Marco Ruffino's attempt to fill this gap by establishing a close link between Frege's treatment of expressions of the form ‘the concept F’ and the privileged status Frege assigns to extensions of concepts as logical objects is bound to fail. I argue, in particular, that Frege's principal motive for introducing extensions into his logical theory (...) is not to be able to make in-direct statements about concepts, but rather to define all numbers as logical objects of a fundamental kind in order to ensure that we have the right cognitive access to them qua logical objects via Axiom V. Contrary to what Ruffino claims, reducibility to extensions cannot be the ‘ultimate criterion’ for Frege of what is to be regarded as a logical object. (shrink)

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

The Hypothesis of Extended Cognition holds that the mind need not be constrained within biological boundaries. However, conditions must be provided to set a principled outer limit on cognitive extension, or implausibly many cases will be implicated. I argue that, for the case of extended beliefs at least, such conditions must pay attention to a mental state's causal history, in addition to its current functional poise. Extended resources can house an individual's beliefs, I propose, only if she has (...) taken responsibility for their sources in a suitable way. (shrink)

The adoption of an explicitly cognitive approach has become prominent in archaeological research during the last decade, helping to place Palaeolithic archaeology into a driving role in the development of archaeological theory and developing inter-disciplinarity with the cognitive sciences. Two prominent approaches have emerged: the social brain hypothesis and the distributed mind. Precisely how these can be integrated into a single, unified approach for the study of the evolution and nature of the human mind remains unclear, if indeed (...) it is desirable to do so. This chapter reflects on the emergence of these approaches within archaeology and comments upon their relative strengths and weakness. (shrink)

This is a review of Andy Clark's book, Supersizing the Mind.

Over the last few decades Michael Dummett developed a rich program for assessing logic and the meaning of the terms of a language. He is also a major exponent of Frege's version of logicism in the philosophy of mathematics. Over the last decade, Neil Tennant developed an extensive version of logicism in Dummettian terms, and Dummett influenced other contemporary logicists such as Crispin Wright and Bob Hale. The purpose of this paper is to explore the prospects for Fregean logicism within (...) a broadly Dummettian framework. The conclusions are mostly negative: Dummett's views on analyticity and the logical/non-logical boundary leave little room for logicism. Dummett's considerations concerning manifestation and separability lead to a conservative extension requirement: if a sentence S is logically true, then there is a proof of S which uses only the introduction and elimination rules of the logical terms that occur in S. If basic arithmetic propositions are logically true-as the logicist contends-then there is tension between this conservation requirement and the ontological commitments of arithmetic. It follows from Dummett's manifestation requirements that if a sentence S is composed entirely of logical terminology, then there is a formal deductive system D such that S is analytic, or logically true, if and only if S is a theorem of D. There is a deep conflict between this result and the essential incompleteness, or as Dummett puts it, the indefinite extensibility, of arithmetic truth. (shrink)

Extended cognition holds that cognitive processes sometimes leak into the world (Dawson, 2013). A recent trend among proponents of extended cognition has been to put pressure on phenomena thought to be safe havens for internalists (Sneddon, 2011; Wilson, 2010; Wilson & Lenart, 2014). This paper attempts to continue this trend by arguing that music perception is an extended phenomenon. It is claimed that because music perception involves the detection of musical invariants within an “acoustic array”, the interaction between the auditory (...) system and the musical invariants can be characterized as an extended computational cognitive system. In articulating this view, the work of J. J. Gibson (1966, 1986) and Robert Wilson (1994, 1995, 2004) is drawn on. The view is defended from several objections and its implications outlined. The paper concludes with a comparison to Krueger’s (2014) view of the “musically extended emotional mind”. (shrink)

The ‘causal-constitution’ fallacy, the ‘cognitive bloat’ worry, and the persisting theoretical confusion about the fundamental difference between the hypotheses of embedded (HEMC) and extended (HEC) cognition are three interrelated worries, whose common point—and the problem they accentuate—is the lack of a principled criterion of constitution. Attempting to address the ‘causal-constitution’ fallacy, mathematically oriented philosophers of mind have previously suggested that the presence of non-linear relations between the inner and the outer contributions is sufficient for cognitive extension. The abstract (...) idea of non-linearity, however, can be easily misunderstood and has, in the past, led to incorrect and counterintuitive conclusions about what may count as part of one’s overall cognitive system. In order to prevent any further mistakes I revisit dynamical systems theory to study the nature of the continuous mutual interactions that give rise to the aforementioned non-linear relations. Moreover, focusing on these interactions will allow us to provide two distinct arguments in support of the ontological postulation of extended cognitive systems, as well as an objective criterion of constitution. Accordingly, I put forward a version of HEC that treats continuous mutual interactions (and the resultant non-linear relations) not just as sufficient but also as necessary for cognitive extension. Such a qualified version of HEC may exclude certain alleged cases of cognitive extension where the agent does not mutually interact with his artifacts (e.g., shopping lists and directory services), but it is immune both to the ‘causal-constitution’ fallacy and the ‘cognitive bloat’ worry, and it can be sharply distinguished from HEMC.

I attempt to show, via considering Schlesinger’s device of putting the word ‘now’ in capitals, that the transient view of time can explicate temporal extensivity without presupposing it, and the static view can’t. The argument hinges on the point that duration is generated by continuance of the present—such that ‘the present’ here is used in a nontechnical, nonindexical, and nonreflexive sense, which Schlesinger and others unknowingly give to the word ‘now’ (by “NOW” or “Now” or “’now’”).

E-approaches to the mind stress the embodied, embedded and enactive nature of mental phenomena. In their more radical, non-representational variants these approaches offer innovative and powerful new ways of understanding fundamental modes of intersubjective social interaction: I-approaches. While promising, E and I accounts have natural limits. In particular, they are unable to explain human competence in making sense of reasons for actions in folk-psychological terms. In this paper I outline the core features of the 'Narrative Practice Hypothesis' (NPH), showing (...) how it might take up that burden in a way which complements non-representationalist E and I accounts. I conclude by addressing a new-order eliminativist challenge from Ratcliffe that questions, inter alia, the very idea that there is anything like a well-defined folk-psychological competence that needs explaining, thereby rendering the NPH otiose. Additionally, I respond to Ratcliffe's claim that the relevant structures needed for the development of that competence do not reveal themselves in relevant narratives, rendering the NPH's developmental story impossible.

Sensory substitution devices provide through an unusual sensory modality (the substituting modality, e.g., audition) access to features of the world that are normally accessed through another sensory modality (the substituted modality, e.g., vision). In this article, we address the question of which sensory modality the acquired perception belongs to. We have recourse to the four traditional criteria that have been used to define sensory modalities: sensory organ, stimuli, properties, and qualitative experience (Grice, 1962), to which we have added the criteria (...) of behavioral equivalence (Morgan, 1977), dedication (Keeley, 2002), and sensorimotor equivalence (O’Regan & Noe¨, 2001). We discuss which of them are fulfilled by perception through sensory substitution devices and whether this favors the view that perception belongs to the substituting or to the substituted modality. Though the application of a number of criteria might be taken to point to the conclusion that perception with a sensory substitution device belongs to the substituted modality, we argue that the evidence leads to an alternative view on sensory substitution. According to this view, the experience after sensory substitution is a transformation, extension, or augmentation of our perceptual capacities, rather than being something equivalent or reducible to an already existing sensory modality. We develop this view by comparing sensory substitution devices to other ‘‘mind-enhancing tools’’ such as pen and paper, sketchpads, or calculators. An analysis of sensory substitution in terms of mind-enhancing tools unveils it as a thoroughly transforming perceptual experience and as giving rise to a novel form of perceptual interaction with the environment.

I discuss Clark’s predictive processing/extended mind hybrid, diagnosing a problem: Clark’s hybrid suggests that, when we use them, we pay attention to mind-extending external resources. This clashes with a commonly accepted necessary condition of cognitive extension; namely, that mind-extending resources must be phenomenally transparent when used. I then propose a solution to this problem claiming that the phenomenal transparency condition should be rejected. To do so, I put forth a parity argument to the effect that phenomenal (...) transparency cannot be a necessary condition on cognitive extension: roughly, since internal cognitive resources can fail to be transparent when used, by parity, external resources can fail to be phenomenally transparent too. Further, I argue that phenomenal transparency is not even a reliable indicator of cognitive extension; hence its absence should not be considered a problem for Clark’s extended mind-predictive processing hybrid. Lastly, I consider and allay a number of worries my proposal might raise, and conclude the paper. (shrink)

This paper investigates the role of a pre-existing body-model that is an enabling constraint for the incorporation of objects into the body. This body-model is also a basis for the distinction between body extensions (e.g., in the case of tool-use) and incorporation (e.g., in the case of successful prosthesis use). It is argued that, in the case of incorporation, changes in the sense of body-ownership involve a reorganization of the body-model, whereas extension of the body with tools does not (...) involve changes in the sense of body-ownership.

This paper questions the form and prospects of “extended theories” which have been simultaneously and independently advocated both in the philosophy of mind and in the philosophy of biology. It focuses on Extend Mind Theory (EMT) and Developmental Systems Theory (DST). It shows first that the two theories vindicate a parallel extension of received views, the former concerning extending cognition beyond the brain, the latter concerned with extending evolution and development beyond the genes. It also shows that (...) both arguments rely on the demonstration of causal parities, which have been undermined by the classical received view. Then I question whether the argument that there is an illegitimate inference from parities or coupling to constitution claims, which has been objected by Adams and Aizawa in The bounds of cognition, (2008) to EMT, also holds against DST. To this aim, I consider two defenses against DST that are parallel to two defenses against EMT, one about intrinsic content, the other about the difference between what’s in principle possible and what happens in practice. I conclude by claiming that the weaknesses and strengths of both theories are different regarding these two kinds of objections. (shrink)

In this paper I look into a problem concerning the characterization of the main conceptual commitments of the ‘post-cognitivist’ theoretical framework. I first consider critically a proposal put forward by Rowlands (2010), which identifies the theoretical nucleus of post-cognitivism with a convergence of the theses of the extended and the embodied mind. The shortcomings I find in this proposal lead me to an indepedent and wider issue concerning the apparent tensions between functionalism and the embodied and enactive approaches.

If you believe more things you thereby run a greater risk of being in error than if you believe fewer things. From the point of view of avoiding error, it is best not to believe anything at all, or to have very uncommitted beliefs. But considering the fact that we all in fact do entertain many specific beliefs, this recommendation is obviously in flagrant dissonance with our actual epistemic practice. Let us call the problem raised by this apparent conflict the (...) Addition Problem. In this paper we will find reasons to reject a particular premise used in the formulation of the Addition Problem, namely, the fundamental premise according to which believing more things increases the risk of error. As we will see, acquiring more beliefs need not decrease the probability of the whole, and hence need not increase the risk of error. In fact, more beliefs can mean an increase in the probability of the whole and a corresponding decrease in the risk of error. We will consider the Addition Problem as it arises in the context of the coherence theory of epistemic justification, while keeping firmly in mind that the point we wish to make is of epistemological importance also outside the specific coherentist dispute. The problem of determining exactly how the probability of the whole system depends on such factors as coherence, reliability and independence will be seen to open up an interesting area of research in which the theory of conditional independence structures is a helpful tool.

Rudolph Carnap’s Aufbau was one of the more ambitious philosophical programs of the twentieth century. His proposal was to begin with elementarerlebnisse —cross sections of one total stream of experience temporally limited by the least perceivable segment of time—and an undefined primitive relation, recollection of similarity, holding between the elementary experiences. Without any further non-logical terms, the goal was to utilize a logic, such as that of Principia Mathematica, and actually to construct logically, or to define formally, all the kinds (...) of entities, phenomenal, physical, psychological and cultural, which we usually take to make up our world. Unfortunately, the program is not completed. Only what Carnap refers to as the lower levels is actually formally constructed—that is, what might be called the phenomenal level. The remainder of the constructional program is only suggested in outline. (shrink)

We begin by introducing our readers to the Extended Mind Thesis and briefly discuss a series of arguments in its favour. We continue by showing of such a theory can be resisted and go on to demonstrate that a more conservative account of cognition can be developed. We acknowledge a stalemate between these two different accounts of cognition and notice a couple of issues that we argue have prevented further progress in the field. To overcome the stalemate, we propose (...) to focus on the ethical implications of these theories. We link work conducted on the Extended Mind Thesis with contemporary transhumanist research and claim that extended may be ethically preferred over embedded because it is a more progressive and inclusive theory.

This article explores the notion of the Web-extended mind, which is the idea that the technological and informational elements of the Web can sometimes serve as part of the mechanistic substrate that realizes human mental states and processes. It is argued that while current forms of the Web may not be particularly suited to the realization of Web-extended minds, new forms of user interaction technology as well as new approaches to information representation do provide promising new opportunities for Web-based (...) forms of cognitive extension. In addition, it is suggested that extended cognitive systems often rely on the emergence of social practices and conventions that shape how a technology is used. Web-extended minds may thus depend on forms of socio-technical co-evolution in which social forces and factors play just as important a role as do the processes of technology design and development.

Intentional actions exhibit control in a way that mere lucky successes do not. A longstanding tradition in action theory characterizes actional control in terms of the _knowledge_ with which one acts when acting intentionally. Given that action theorists, no less than epistemologists, typically take for granted the orthodox thesis that knowledge is in the head (viz., realized exclusively by brainbound cognition), the idea that intentional action is controlled in virtue of knowledge is tantamount to the idea that the knowledge by (...) which intentional actions exhibit control supervenes intracranially. We raise some challenges for this idea, and in doing show, we show how epistemic theories of actional control are naturally aligned moreso than has been appreciated with cognitive extension in the theory of mind.

This paper examines the application of the mutual manipulability criterion as a way to demarcate constituents of cognitive systems from resources having a mere causal influence on cognitive systems. In particular, it is argued that on at least one interpretation of the mutual manipulability criterion, the criterion is inadequate because the criterion is conceptualized as identifying synchronic dependence between higher and lower ‘levels’ in mechanisms. It is argued that there is a second articulation of the mutual manipulability criterion available, and (...) that it should be preferred for at least two reasons. The first is that the criterion of mutual manipulability is an instance of continuous reciprocal causation. The second is that it has implications for how to understand this distinction between causation and constitution. It is shown that when considering dynamic systems, continuous reciprocal causation - ubiquitous in dynamical systems - is a form of constitutive causality, which entails that causal factors may, in the right circumstances, by genuine constitutive factors of cognition. This notion of constitutive causality lends support to conceiving of the mutual manipulability criterion as a genuine demarcation principle in the debate over the boundaries of mind. (shrink)

In this paper, I address one recent objection to Andy Clark and David Chalmers’s functionalist argument for the extended mind thesis. This objection is posed by Kengo Miyazono, who claims that they unjustifiably identify the original cognitive subject with the hybrid one in order to reach their conclusion about the mind extension. His attack consists of three steps: distinguishing hybrid from traditional cognitive subjects based on the systems reply originally directed at Searle’s Chinese room argument; pointing out (...) that the conclusion of the functionalist argument for EM must be rephrased to state that there are hybrid, and not extended, systems with widely realized mental states; and arguing that functionalist EM cannot justify the assumption about the identity of these two kinds of subjects without circularity. I argue that Miyazono’s main argument is ill-founded but that it, nevertheless, points out one important issue, namely, that we need further justification of the identity assumption, without which EM loses much of its flavor. Thus, I am going to challenge Miyazono’s argument, provide a reinterpretation of the argumentation in the EM debate, defend the possibility of wide and extended selves, and offer a justification of the identity assumption, which I find crucial not only for vindicating EM but also for differentiating EM from other similar theses, such as the thesis about group minds.

In this paper we study the combined structure of the relations of theory-extension and interpretability between theories for the case of finitely axiomatised theories. We focus on two main questions. The first is definability of salient notions in terms of the structure. We show, for example, that local tolerance, locally faithful interpretability and the finite model property are definable over the structure. The second question is how to think about ‘good’ properties of theories that are independent of implementation details (...) and of ‘bad’ properties that do depend on implementation details. Our degree structure is suitable to study this contrast, since one of our basic relations, to wit theory-extension, is dependent on implementation details and the other relation, interpretability, is not. Nevertheless, we can define new good properties using bad ones. We introduce a new notion of sameness of theories i-bisimilarity that is second-order definable over our structure. We define a notion of goodness in terms of this relation. We call this notion being capital. We illustrate that some intuitively good properties, like being a complete theory, are not capital.
