The Empiricist or Lockean view says natural kinds do not exist objectively in nature but are practical categories reflecting use of words. The Modern, Ostensive view says they do exist, and one can refer to such a kind by ostention and recursion, assuming his designation of it is related causally to the kind itself. However, this leads to a problem: Kinds are abstract repeatables, and it seems impossible that abstractions could have causal force. In defence of the Modern view, I (...) suggest we can think of kinds as — or as like — ecological niches existing in nature, which are causally effective by virtue of the fact that they predictively determine (some) properties of the things that happen to occupy them.

ABSTRACT Our ascriptions of content to past utterances assign to them a level of conceptual continuity and determinacy that extends beyond what could be grounded in the usage up to their time of utterance. If one accepts such ascriptions, one can argue either that future use must be added to the grounding base, or that such cases show that meaning is not, ultimately, grounded in use. The following will defend the first option as the more promising of the two, though (...) this ultimately requires understanding the relation between use and meaning as ‘normative’ in two important ways. The first way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between actual and correct use. The second sort of normativity is unique to theories that extend the grounding base into the future. In particular, if meaning is partially a function of future use, we can see our commitment to the ‘determinacy’ of meaning as a practical commitment that structures our linguistic practices rather than a theoretical commitment that merely describes them.

First, I argue that the narrow content of a thought cannot be identical with the linguistic meaning of the sentence used to express it. Secondly, I argue that the distinction between narrow content and linguistic meaning is not fatal to content-dualism. Thirdly I argue for the view that the proposition contributed by the clause prefixed by "that" is an interpretation of the believer's thought. Finally, I use this insight to provide an individualist account of Burge's thought-experiments such that recognition that (...) the truth-conditions of belief-ascriptions include aspects of the believer's environment does not entail that those environmental aspects are thereby parts of the contents of the person's thoughts.

Annotated bibliography of works on externalism and internalism in the philosophy of mind.

Words change meaning over time. Some meaning shift is accompanied by a corresponding change in subject matter; some meaning shift is not. In this paper I argue that an account of linguistic meaning can accommodate the first kind of case, but that a theory of concepts is required to accommodate the second. Where there is stability of subject matter through linguistic change, it is concepts that provide the stability. The stability provided by concepts allows for genuine disagreement and ameliorative change (...) in the context of conceptual engineering. (shrink)

It's widely accepted that social facts about an individual's linguistic community can affect both the reference of her words and the concepts those words express. Theorists sympathetic to the internalist tradition have sought to accommodate these social dependence phenomena without altering their core theoretical commitments by positing deferential reference-fixing criteria. In this paper, we sketch a different explanation of social dependence phenomena, according to which all concepts are individuated in part by causal-historical relations linking token elements of thought.

Tyler Burge says that first-person authority can be reconciled with anti-individualism about the intentional by denying part of the "Cartesian conception" of authority, which claims that I am actually authoritative about my intentional attitudes in counterfactual situations. This clause, he says, wrongly conflates the evaluation-conditions for sceptical doubts about the "external" world with the conditions for classifying intentional attitudes in counterfactual situations. This paper argues that the kind of possibility needed to understand external-world scepticism justifies the conflation and that Burge (...) can reject the Cartesian conception only if he rejects either metaphysical realism or anti-individualism.

I argue that entertaining a proposition is not an action. Such events do not have intentional explanations and cannot be evaluated as rational or not. In these respects they contrast with assertions and compare well with perceptual events. One can control what one thinks by doing something, most familiarly by reciting a sentence. But even then the event of entertaining the proposition is not an action, though it is an event one has caused to happen, much as one might cause (...) oneself to see a book by looking at it. I also discuss how this may support the view that thinking about the world is a source of information about it. (shrink)

_ Source: _Page Count 25 This is a pre-print. Please cite only the revised published version. This paper presents an original, ambitious, truth-directed transcendental argument for the existence of an ‘external world’. It begins with a double-headed starting-point: Stroud’s own remarks on the necessary conditions of language in general, and Hegel’s critique of the “fear of error.” The paper argues that the sceptical challenge requires a particular critical concept of thought as that which may diverge from reality, and that this (...) concept is possible only through reflection on situations of error, in which how things are thought to be diverges from how things really are with independent items in an objective world. The existence of such a world is therefore a necessary condition of the possibility of scepticism: such scepticism is therefore false. I defend the argument against objections from Stroud’s sceptic and others. Drawing on Heidegger, the paper concludes by indicating that the chain of necessary conditions includes practical engagement with the world. (shrink)

The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

The purpose of the paper is to show that semanticexternalism – the thesis that contents are notdetermined by ``individualistic'' features of mentalstates – is mistaken. Externalist thinking, it isargued, rests on two mistaken assumptions: theassumption that if there is an externalist wayof describing a situation the situation exemplifiesexternalism, and the assumption that cases in which adifference in the environment of an intentional stateentails a difference in the state's intentional objectare cases in which environmental factors determine thestate's content. Exposing these mistakes (...) leads to seethat the conditions that are required for thetruth of externalism are inconsistent. (shrink)

In this article I argue for a novel theory of representational content, which I call ‘subjective externalism’. The view combines an internal, subjective constraint on the attribution of thought content which traditionally underpins internalist theories of thought, and an external, objective constraint on the attribution of thought content which traditionally underpins externalist theories of thought. While internalism and externalism are mutually inconsistent, the constraints to which each theory is committed are not. It is this realization that opens up the conceptual (...) space for subjective externalism, according to which the correct attribution of thought content to an individual is essentially constrained by her nonrepresentational relations to objective manifest properties in her wider reality.

This dissertation contains four independent essays addressing a cluster of related topics in the philosophy of mind. Chapter 1: “Fundamentality Physicalism” argues that physicalism can usefully be conceived of as a thesis about fundamentality. The chapter explores a variety of other potential formulations of physicalism (particularly modal formulations), contrasts fundamentality physicalism with these theses, and offers reasons to prefer fundamentality physicalism over these rivals. Chapter 2:“Modal Rationalism and the Demonstrative Reply to the Master Argument Against Physicalism” introduces the Master Argument (...) Against Physicalism and investigates its crucial premise: the inference from an a priori gap between the physical and consciousness to a lack of necessitation between the two. I argue against the strong form of modal rationalism that underwrites the master argument and offer a more moderate rationalist view. I offer a novel demonstrative reply to the master argument, according to which a connection between conscious experience and demonstratives, not dualism, is the source of the epistemic gap between consciousness and the physical. Chapter 3: “Conceptual Mastery and the Knowledge Argument” argues that Frank Jackson’s famous anti-physicalist knowledge argument featuring Mary, a brilliant neuroscientist raised in a black and white room, founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been removed, Mary can know the relevant truths. Chapter 4: “Toward a Theory of Conceptual Mastery” investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I argue against three views of conceptual mastery, according to which conceptual mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. I propose and respond to objections to my own “meaning postulate view” of the conditions under which a thinker has mastery of a concept. (shrink)

In recent philosophy of mind a non-holistic view on concept possession, originally developed by Tyler Burge, has emerged as an alternative to holistic analyses of language mastery. The article discusses the implications of this view for analyses of communication in doctor—patient-interaction. The central question Burge's theory gives an answer to is this: to what extent must a doctor and a patient understand a medical term in the same way in order to communicate in the sense that they express the same (...) concept by the term? Many empirical studies have shown that patients do not, typically, understand medical terms in the same way as doctors they encounter. Holistic approaches therefore imply that doctors and patients seldom communicate. Burge's position, on the other hand, implies that it is sufficient that patients have a minimal understanding. In an important range of cases doctors can make sure that patients have a minimal understanding by being explicit about common dictionary definitions of the terms in question. (shrink)

According to Clarke and Beck (C&B), the approximate number system (ANS) represents numbers. We argue that the ANS represents pure magnitudes. Considerations of explanatory economy favor the pure magnitudes hypothesis. The considerations C&B direct against the pure magnitudes hypothesis do not have force.

In this paper, I propose a new way of understanding the space of possibilities in the field of mental content. The resulting map assigns separate locations to theories of content that have generally been lumped together on the more traditional map. Conversely, it clusters together some theories of content that have typically been regarded as occupying opposite poles. I make my points concrete by developing a taxonomy of theories of mental content, but the main points of the paper concern not (...) merely how to classify, but how to understand, the theories. Also, though the paper takes theories of mental content as a case study, much of the discussion is applicable to theories of other phenomena. To a first approximation, the difference between the traditional and the proposed taxonomies turns on whether we classify theories of content by, on the one hand, their implications for a non-redundant supervenience base for content facts (i.e., for facts about what contents thoughts have) or, on the other, by their constitutive accounts of content. By a "constitutive account," I mean the kind of elucidation of the nature of a phenomenon that theorists have tried to give for, for example, knowledge, justice, personal identity, consciousness, convention, heat, and limit. The tendency to taxonomize by supervenience base is encouraged, I suggest, by a failure to keep clearly in view a distinction between constitutive and modal determination. Many philosophers would accept that a constitutive account cannot be captured in purely modal terms. Giving a constitutive account is not the same as specifying modally necessary and sufficient conditions. Nevertheless, philosophers often try to cash constitutive claims in modal terms. A case in point is that theories of content tend to be conceptualized in terms of the theories' implications for a supervenience base for content facts. My thesis goes beyond the by-now somewhat familiar proposition that not all modal determinants of a phenomenon are constitutive determinants. One who has taken that point on board might nevertheless conceive of a philosophical account as an attempt to specify constitutive determinants of the target phenomenon that make up a non-redundant supervenience base for the phenomenon. Shoehorning a philosophical account into this form leaves out elements that are modally redundant, but may be explanatorily or ontologically significant. For example, when a constitutive account has multiple levels, the different levels will typically be modally redundant. Formulating the account as a specification of a supervenience base of constitutive determinants will therefore flatten the account into a single level. Many of my arguments can be illustrated by considering the place of normativity in the theory of content. The new taxonomy gives a distinct niche to normative theories of content - theories that explain a thought's having a certain content at least in part in terms of the obtaining of normative facts. By contrast, on a traditional map, normative theories are invisible as such because normative facts supervene on non-normative ones. (shrink)

What is the best account of process reliabilism about epistemic justification, especially epistemic entitlement? I argue that entitlement consists in the normal functioning (proper operation) of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Etiological functions involve consequence explanation: a belief-forming process has forming true beliefs reliably as a function just in case forming-true beliefs reliably partly explains the persistence of the process. This account paves the way for avoiding standard objections to process (...) reliabilism and situations epistemic entitlement within a normative framework of functions and functional norms. (shrink)

Frege’s ‘differential dubitability’ test is a test for differences in cognitive value: if one can rationally believe that p while simultaneously doubting that q, then the contents p and q amount to different ‘cognitive values’. If subject S is rational, does her simultaneous adoption of different attitudes towards p and q require that the difference between p and q(as cognitive values) be transparent to her? It is natural to think so. But I argue that, if attitude anti-individualism is true, then (...) rational differential dubitability does not presuppose that differences in cognitive value be transparent. The significance of this argument lies in what it tells us, both about the notion of cognitive value (and its relation to the differential dubitability test), but also about the prospects for a Burge-type position which aims to combine attitude anti-individualism with a (perhaps qualified) reliance on the differential dubitability test. (shrink)

Given anti-individualism, a subject might have a priori (non-empirical)knowledge that she herself is thinking that p, have complete and exhaustive explicational knowledge of all of the concepts composing the content that p, and yet still need empirical information (e.g. regarding her embedding conditions and history) prior to being in a position to apply her exhaustive conceptual knowledge in a knowledgeable way to the thought that p. This result should be welcomed by anti-individualists: it squares with everything that compatibilist-minded anti-individualists have (...) said regarding e.g. the compatibility of anti-individualism and basic self-knowledge; and more importantly it contains the crux of a response to McKinsey-style arguments against anti-individualism.

Natural kind terms have exercised philosophical fancy ever since Kripke, in Naming and Necessity, claimed them to be rigid designators. He there drew attention to the peculiar, name-like behavior of a family of prima facie loosely related general terms of ordinary English: terms such as ‘water’, ‘tiger’, ‘heat’, and ‘red’. Just as for ordinary proper names, Kripke argued that such terms cannot be synonymous with any of the definite descriptions ordinary speakers associate with them. Rather, the name-like behavior of these (...) so-called natural kind terms is to be explained, just as in in the case of proper names, by the doctrine of rigid designation. And as a consequence of thus extending the notion of rigid designation to general terms, he famously endorsed the claim that so-called ‘theoretical identifications’, i.e. statements like (1) Water is H2O, are necessary, if true.

The idea that there is an inherent incentive in moral judgment or, in Classical terms, that there is an essential relationship between virtue and well?being is sharply criticized in contemporary moral theory. The associated theses that there is a way of living which is objectively good for human beings and that living that way is part of understanding moral truth are equally problematic. The Aristotelian argument proceeded via the premise that a human being was a rational social being. The present (...) reworking of that thesis builds on the internal connection between rationality and concept use. Moral judgment is linked to the grasp of moral concepts and thereby to an appreciation of how it is with other persons. The judgment that another person instances a morally relevant ascription is grounded on an empathic grasp of how it is with that person and thus tied to the thought that one ought to act in such and such a way or. in other words, to a disposition to act. Because the empathically grasped content of moral concepts is related to a number of mental ascriptions and reactive attitudes, the grasp of that content is interwoven deeply in the structure of human mental life and any attempt systematically to devalue or undermine it is threatening to one's mental integrity as a rational social being. Thus there is a deep link between moral sense or the disposition to act morally and an adequately grounded conception of human well?being. (shrink)

Recent developments in technologically enabled social cognition call for a rethinking of many aspects of human cognition. According to the hypothesis of extended cognition, we must revise our psychological categories by eliminating allegedly superficial distinctions between internal cognition and external processes. As an alternative to this proposal, I outline a hypothesis of outsourced cognition which seeks to respect distinctions that are operative in both folk psychology and the social and cognitive sciences. According to this hypothesis, the cognitive states and processes (...) of the individual are substantially and explanatorily distinct from the relevant external states and processes. In consequence, the individual remains a cognitive unit that is both central and indispensable in the explanations of cognitive science. As a case study, I consider the epistemology of testimony. I will argue that important epistemological categories may be preserved by adopting the hypothesis of outsourced cognition over the hypothesis of extended cognition. Moreover, I will argue that the outsourced cognition hypothesis deepens the problems that beset an extended epistemology of testimony. (shrink)

To illustrate the view that a speaker can have a partial understanding of a concept, Burge uses the example of Leibniz’s and Newton’s understanding of the concept of derivative. In a recent article, Sheldon Smith criticizes this example and maintains that Newton’s and Leibniz’s use of their derivative symbols does not univocally determine their references. The present article aims at challenging Smith’s analysis. It first shows that Smith misconstrues Burge’s position. It second suggests that the philosophical lessons one should draw (...) from the practice of the historians of philosophy are more ambivalent than what Smith thinks. (shrink)

The Burge-Putnam thought experiments have generated the thesis that beliefs are not fixed by the constitution of the body. However, many philosophers have thought that if this is true then there must be another content-like property. Even if the contents of our attitudes such as the one in ‘believes that aluminum is a light metal’, do not supervene on our physical makeups, nevertheless people who are physical duplicates must be the same when it comes to evaluating their rationality and explaining (...) their actions. I argue that the considerations motivating this view are best handled with just the ordinary ‘that’-clause contents. (shrink)

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as well as a (...) rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privileged (...) access.

Abstract: This paper introduces and analyses the doctrine of externalism about semantic content; discusses the Twin Earth argument for externalism and the assumptions behind it, and examines the question of whether externalism about content is compatible with a privileged knowledge of meanings and mental contents.

Some content externalists claim that if C is a theoretical concept and “C” expresses C, then the content of C in a community at a time is determined by how some members of the community at the time—call them “experts”—understand C or use “C”. Thus, when non-expert Chauncey utters “C”, the content of the concept he expresses does not depend entirely on his intrinsic physical properties, contra the claims of content internalism. This paper proposes that “concept” expresses a theoretical concept, (...) such that the externalist’s insights should apply to how we understand claims expressing the view itself and to how we evaluate the arguments alleged to motivate it. With respect to the first, I argue that the content externalist should regard it as unclear at present which proposition her theory expresses, and should take it that content externalism teaches us about our linguistic community rather than about the metaphysical nature of concepts. With respect to the second, I argue that by externalism’s own lights, the famous externalist thought experiments shouldn’t establish content externalism. In conclusion, I suggest that making sense of content externalism requires presupposing internalism. (shrink)

This paper exposes a common mistake concerning the division of linguistic labor. I characterize the mistake as an overgeneralization from natural kind terms; this misleads philosophers about which terms are subject to the division of linguistic labor, what linguistic labor is, how linguistic labor is divided, and how the extensions of non-natural kind terms subject to the division of linguistic labor are determined. I illustrate these points by considering Sally Haslanger’s account of the division of linguistic labor for social kind (...) terms and raising an objection to it. Then, I draw on Tyler Burge’s work to characterize a conception of the division of linguistic labor that avoids the mistaken overgeneralization and grounds 1–4 above in social norms and practices.

Quine's (1969) proposal that the foundationalist programs in epistemology should be abandoned in favor of a scientific study of how we come to hold our theories about the world is still widely misunderstood. It does not eliminate the possibility of rational adjudication of scientific dispute, nor is it essentially tied to behaviorist approaches in psychology. On the contrary, recent work in psychology and philosophy of science can very naturally be seen as embodying the sort of program envisioned by Quine; now (...) freed of behaviorist strictures, it clearly addresses issues that have been of interest in traditional epistemology. This view is defended with particular attention to Quine's concerns with translation and the related concerns with belief individuation which have inspired critics of recent cognitive psychology.

This paper explores the psychological analogues of a cluster of arguments that have played an important role in motivating a now widespread, reference-based approach in philosophy of language. What I will call the psychological analogues of Kripke-style arguments provide a substantial motivation for a reference-based approach to concepts. Insofar as such an approach is rarely given serious consideration, the availability of these arguments suggests the need for a rethinking of some foundational assumptions in philosophy of mind and other branches of (...) the cognitive sciences.

The dominant tradition in analytic philosophy of language views reference as paradigmatically enabled by the acquisition of words from other speakers. Via chains of transmission, these words connect the referrer to the referent. Such a picture assumes the notion of a word as a stable mapping between sound and meaning. Utterances are constructed out of such stable mappings. While this picture of language is both intuitive and historically distinguished, various trends and programs that have developed over the last few decades (...) in theoretical linguistics suggest an alternative. According to these approaches, the word, conceived of as a linguistic ‘building block’, has no special theoretical significance. While natural language systems generate structures mapping sounds onto meanings, they need not do so by composing elements which themselves specify such mappings. I shall describe some of these developments, and show how they pose a problem for traditional philosophical views of language and communication, before identifying an alternative approach to reference which does not rely on this common-sense picture of words.

The first explicit argument for the incompatibility of externalism in the philosophy of mind and a priori self-knowledge is Boghossian’s discrimination argument. In this essay, I oppose the third premise of this argument, trying to show by means of a thought experiment that possessing the “twater thought” is not an alternative, a fortiori not a relevant alternative, to having the “water thought.” I then examine a modified version of Boghossian’s argument. The attempt is made to substantiate the claim that the (...) standard incompatibilist support for its second premise is untenable. Furthermore, a third Boghossian-style argument is rejected on the ground that either its second premise cannot be warranted in the way suggested by incompatibilists or its third premise is mistaken because having the “twater thought” instead of the “water thought” is not relevant. Finally, it is argued that the discrimination argument cannot be saved by invoking closure. The upshot of my discussion is that a compatibilist can dismiss Boghossian-style arguments for incompatibilism without having to deal with fundamental issues concerning self-knowledge and the nature of slow switching.

Individualism is the doctrine that the state of one's mind is entirely dependent on the state of one's body (or some proper part thereof (e.g., the central nervous system)). It has come under attack from Burge, Baker, and others. This paper seeks to cut off one ore attempt to defend individualism, namely, the claim that experience, at least, in individualistic.

This should be fairly close to the text of this paper as it appears in The Southern Journal of Philosophy 38 (2000), Spindel Conference Supplement: 121-148.

It is argued that Husserl was an “externalist” in at least one sense. For it is argued that Husserl held that genuinely perceptual experiences—that is to say, experiences that are of some real object in the world—differ intrinsically, essentially and as a kind from any hallucinatory experiences. There is, therefore, no neutral “content” that such perceptual experiences share with hallucinations, differing from them only over whether some additional non-psychological condition holds or not. In short, it is argued that Husserl was (...) a “disjunctivist”. In addition, it is argued that Husserl held that the individual object of any experience, perceptual or hallucinatory, is essential to and partly constitutive of that experience. The argument focuses on three aspects of Husserl’s thought: his account of intentional objects, his notion of horizon, and his account of reality. (shrink)

This paper addresses a problem about epistemic warrant. The problem is posed by philosophical arguments for externalism about the contents of thoughts, and similarly by philosophical arguments for architecturalism about thinking, when these arguments are put together with a thesis of first person authority. In each case, first personal knowledge about our thoughts plus the kind of knowledge that is provided by a philosophical argument seem, together, to open an unacceptably ‘non-empirical’ route to knowledge of empirical facts. Furthermore, this unwelcome (...) prospect of transferring a ‘non-empirical’ warrant from premises about our own mental states and about philosophical theory to a conclusion about external environment or internal architecture seems to depend upon little more than the possibility of knowledge by inference. (The use of the scare-quoted term ‘non-empirical’ is explained a couple of paragraphs further on.). (shrink)

This paper argues that Twin Earth twins belong to the same psychological natural kind, but that the reason for this is not that the causal powers of mental states supervene on local neural structure. Fodor’s argument for this latter thesis is criticized and found to rest on a confusion between it and the claim that Putnamian and Burgean type relational psychological properties do not affect the causal powers of the mental states that have them. While it is true that Putnamian (...) and Burgean type relational psychological properties do not affect causal powers, it is false that no relational psychological properties do. Examples of relational psychological properties that do affect causal powers are given and psychological laws are sketched that subsume twins in virtue of them instantiating these relational properties rather than them sharing the narrow contents of their thoughts.

This paper argues for an account of the relation between thought ascription and the explanation of action according to which de re ascriptions and de dicto ascriptions of thought each form the basis for two different kinds of action explanations, nonrationalizing and rationalizing ones. The claim that de dicto ascriptions explain action is familiar and virtually beyond dispute; the claim that that de re ascriptions are explanatory of action, however, is not at all familiar and indeed has mostly been denied (...) by philosophers. I explain how de re ascriptions enter into non-rationalizing explanations of action and how attention to their distinctive explanatory nature reveals flaws in an alternative “dual-component” view about action explanation.

On a now orthodox view, humans and many other animals possess a “number sense,” or approximate number system, that represents number. Recently, this orthodox view has been subject to numerous critiques that question whether the ANS genuinely represents number. We distinguish three lines of critique – the arguments from congruency, confounds, and imprecision – and show that none succeed. We then provide positive reasons to think that the ANS genuinely represents numbers, and not just non-numerical confounds or exotic substitutes for (...) number, such as “numerosities” or “quanticals,” as critics propose. In so doing, we raise a neglected question: numbers of what kind? Proponents of the orthodox view have been remarkably coy on this issue. But this is unsatisfactory since the predictions of the orthodox view, including the situations in which the ANS is expected to succeed or fail, turn on the kind of number being represented. In response, we propose that the ANS represents not only natural numbers, but also non-natural rational numbers. It does not represent irrational numbers, however, and thereby fails to represent the real numbers more generally. This distances our proposal from existing conjectures, refines our understanding of the ANS, and paves the way for future research. (shrink)
