"This is an important new Cummins work.

In exploring the nature of psychological explanation, this book looks at how psychologists theorize about the human ability to calculate, to speak a language and the like. It shows how good theorizing explains or tries to explain such abilities as perception and cognition. It recasts the familiar explanations of "intelligence" and "cognitive capacity" as put forward by philosophers such as Fodor, Dennett, and others in terms of a theory of explanation that makes established doctrine more intelligible to professionals and their (...) students.In particular, the book shows that vestigial adherence to the positivists' D-N model has distorted the view of philosophers of science about what psychologists (and biologists) do and has masked the real nature of explanation. Major sections in the book cover Analysis and Subsumption; Functional Analysis; Understanding Cognitive Capacities; and Historical Reflections.Robert Cummins is Associate Professor of Philosophy at the University of Illinois, Chicago Circle.

As a procedure, reflective equilibrium is simply a familiar kind of standard scientific method with a new name. A theory is constructed to account for a set of observations. Recalcitrant data may be rejected as noise or explained away as the effects of interference of some sort. Recalcitrant data that cannot be plausibly dismissed force emendations in theory. What counts as a plausible dismissal depends, among other things, on the going theory, as well as on background theory and on knowledge (...) that may be relevant to under-standing the experimental design that is generating the observations, including knowledge of the apparatus and observation conditions. This sort of mutual adjustment between theory and data is a familiar feature of scientific practice. Whatever authority RE seems to have comes, I think, from a tacit or explicit recognition that it has the same form as this familiar sort of scientific inference. One way to see the rationale underlying this procedure in science is to focus on prediction. Think of prediction as a matter of projecting what is known onto uncharted territory. To do this, you need a vehicle—a theory—that captures some invariant or pattern in what is known so that you can project it onto the unknown. How convincing the projection is depends on two factors: how sure one is of the observational base, and how sure one is that the theory gets the invariants right. The two factors are not independent, of course. One's confidence in the observational base will be affected by how persuasively the theory identifies and dismisses noise; one's confidence in the theory, on the other hand, will depend on one's confidence in the observations it takes seriously. Prediction is important as a test of theory precisely because verified predictions seem to show that the theory has correctly captured the general in the particular, that it has got the drift of the observational evidence in which our confidence is ultimately grounded.

The current debate over systematicity concerns the formal conditions a scheme of mental representation must satisfy in order to explain the systematicity of thought.1 The systematicity of thought is assumed to be a pervasive property of minds, and can be characterized (roughly) as follows: anyone who can think T can think systematic variants of T, where the systematic variants of T are found by permuting T’s constituents. So, for example, it is an alleged fact that anyone who can think the (...) thought that John loves Mary can think the thought that Mary loves John, where the latter thought is a systematic variant of the former.

Neo-teleology is the two part thesis that, e.g., (i) we have hearts because of what hearts are for: Hearts are for blood circulation, not the production of a pulse, so hearts are there--animals have them--because their function is to circulate the blood, and (ii) that (i) is explained by natural selection: traits spread through populations because of their functions. This paper attacks this popular doctrine. The presence of a biological trait or structure is not explained by appeal to its function. (...) To suppose otherwise is to trivialize natural selection.

Certain recurring themes have emerged from research on intelligent behavior from literatures as diverse as developmental psychology, artificial intelligence, human reasoning and problem solving, and primatology. These themes include the importance of sensitivity to goal structure rather than action sequences in intelligent learning, the capacity to construct and manipulate hierarchically embedded mental representations, and a troubling domain specificity in the manifestation of each.

The standard explanation for the origin of bilateral symmetry is that it conferred an advantage over radial symmetry for directed locomotion. However, recent developmental and phylogenetic studies suggest that bilateral symmetry may have evolved in a sessile benthic animal, predating the origin of directed locomotion. An evolutionarily feasible alternative explanation is that bilateral symmetry evolved to improve the efficiency of internal circulation by affecting the compartmentalization of the gut and the location of major ciliary tracts. This functional design principle is (...) illustrated best by the phylum Cnidaria where symmetry varies from radial to tetraradial, biradial and bilateral. In the Cnidaria, bilateral symmetry is manifest most strongly in the internal anatomy and the disposition of ciliary tracts. Furthermore, the bilaterally symmetrical Cnidaria are typically sessile and, in those bilaterally symmetrical cnidarians that undergo directed locomotion, the secondary body axis does not bear a consistent orientation to the direction of locomotion as it typically does in Bilateria. Within the Cnidaria, the hypothesized advantage of bilateral symmetry for internal circulation can be tested by experimental analysis and computer modeling of fluid mechanics. The developmental evolution of symmetry within the Cnidaria can be further explored through comparative gene expression studies among species whose symmetry varies.

Looks at accounts by Locke, Fodor, Dretske, and Millikan concerning the nature of mental representation, and discusses connectionism and representation.

It has been generally assumed that certain categories of numerical expressions, such as ‘more than n’, ‘at least n’, and ‘fewer than n’, systematically fail to give rise to scalar implicatures in unembedded declarative contexts. Various proposals have been developed to explain this perceived absence. In this paper, we consider the relevance of scale granularity to scalar implicature, and make two novel predictions: first, that scalar implicatures are in fact available from these numerical expressions at the appropriate granularity level, and (...) second, that these implicatures are attenuated if the numeral has been previously mentioned or is otherwise salient in the context. We present novel experimental data in support of both of these predictions, and discuss the implications of this for recent accounts of numerical quantifier usage. (shrink)

This article attempts to motivate a reorientation of ethical analysis of conscientious objection by physicians. First, it presents an illustrative case from a hospital emergency department for context. Then, it criticizes the standard pro- and anti-CO arguments. It proposes that the fault in standard approaches is to focus on the ethics of the physician’s behavior, and a better way forward on this issue is to ask how the party against whom the physician exercises the CO ought to respond. It connects (...) this question with recent trends in physician employment models, which suggest that CO may become a potential source of conflict in the future. The article then develops a relational account of CO that extends James Childress’ insights about the nature of CO in “Appeals to Conscience”. This relational account characterizes CO as a two-place relation between conscientious objector and expectant party, in which the conscientious objector makes a request of the expectant party, which has implications that will be welcome and unwelcome for both the pro- and anti-CO camps. Finally, the paper applies this relational account of CO to the case when the physician is an employee. This application demonstrates that it is highly context dependent whether or not an employer should accede to the CO requests of physician–employees. (shrink)

What are the prospects for a cognitive science of meaning? As stated, we think this question is ill posed, for it invites the conflation of several importantly different semantic concepts. In this paper, we want to distinguish the sort of meaning that is an explanandum for cognitive science—something we are going to call meaning—from the sort of meaning that is an explanans in cognitive science—something we are not going to call meaning at all, but rather content. What we are going (...) to call meaning is paradigmatically a property of linguistic expressions or acts: what one’s utterance or sentence means, and what one means by it. What we are going to call content is a property of, among other things, mental representations and indicator signals. We will argue that it is a mistake to identify meaning with content, and that, once this is appreciated, some serious problems emerge for grounding meaning in the sorts of content that cognitive science is likely to provide.

The thesis of this paper is that the causal theory of mental content (hereafter CT) is incompatible with an elementary fact of perceptual psychology, namely, that the detection of distal properties generally requires the mediation of a “theory.” I shall call this fact the nontransducibility of distal properties (hereafter NTDP). The argument proceeds in two stages. The burden of stage one is that, taken together, CT and the language of thought hypothesis (hereafter LOT) are incompatible with NTDP. The burden of (...) stage two is that acceptance of CT requires acceptance of LOT as well. It follows that CT is incompatible with NTDP. I organize things in this way in part because it makes the argument easier to understand, and in part because the stage-two thesis—that CT entails LOT—has some independent interest and is therefore worth separating from the rest of the argument.

This is a condensed version of the material in chapters 8-10 in Meaning and Mental Representation (MIT, 1989). It is an explanation and defence of a theory of content for the mind considered as a symbolic computational process. It is a view i abandoned shortly thereafter when I abandoned symbolic computatioalism as a viable theory of cognition.

In the beginning, there was the DN (Deductive Nomological) model of explanation, articulated by Hempel and Oppenheim (1948). According to DN, scientific explanation is subsumption under natural law. Individual events are explained by deducing them from laws together with initial conditions (or boundary conditions), and laws are explained by deriving them from other more fundamental laws, as, for example, the simple pendulum law is derived from Newton's laws of motion.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXI, Number 1, April 1995, pp. 47-55 Hume as Dualist and Anti-Dualist PHILLIP D. CUMMINS Lome Falkenstein's recognition in "Hume and Reid on the Simplicity of the Soul" of the importance of the section of A Treatise of Human Nature entitled "Of the immateriality of the soul" is as praiseworthy as it is uncommon. His suggestion that Reid's intentionalist account of representation was motivated by (...) his desire to save the doctrine of the immaterial self from Hume's demolition of it in "Of the immateriality of the soul," though not proven, is highly provocative. Although I am going to offer a somewhat different reading of "Of the immateriality of the soul" and thereby imply that Falkenstein did not sufficiently appreciate Hume's version of mental-physical dualism, I regard his paper as both informative and insightful and consider my proposed corrections fully compatible with most, if not all, of his substantive claims. Let me begin by contrasting two questions relating to mental-physical dualism. One is whether mental states or properties are irreducibly different from physical states or properties. Materialists generally acknowledge that there is an apparent, putative, or presumed difference between them, only to argue one way or another that the only genuine properties are material ones. Defenders of what I shall call Minimal Mental/Physical Dualism insist that the distinction between two fundamentally different kinds of properties remains at even the deepest levels of metaphysical analysis. One version of the second question is: Are there any immaterial beings? This question really concerns individual subjects, the items to which states or properties are assigned; it asks: do any individual subjects have only mental properties? To answer "yes" is to Phillip D. Cummins is at the Department of Philosophy, 269 English Philosophy Building, The University of Iowa, Iowa City, IA 52242-1408 USA. e-mail: phillip-cummins@uiowa.edu 48 Phillip D. Cummins hold what I shall call Strong Mental/Physical Dualism. Its opponents either answer "no" or take an agnostic stance. The two questions are not completely unrelated.1 As Descartes argued in the Sixth Meditation, an irreducible difference between mental and physical properties guarantees at least the metaphysical possibility of a disembodied mind.2 Despite this, an affirmative answer to the first question does not secure an affirmative answer to the second question. Minimal Mental/Physical Dualism does not entail Strong Mental/Physical Dualism. If it is possible for the same individual subject to have both mental and physical properties, it may be the case that whenever an individual subject has a mental property it also has a physical property.3 Consequently, an obvious strategy for establishing Strong Mental/ Physical Dualism is defending the impossibility of an individual subject's having both mental and physical properties, that is, arguing that the two kinds of properties are essentially incompatible with one another. Call this the Incompatible Properties Thesis. If it can be secured, to discover an individual with a mental property is virtually to discover an immaterial thing. Descartes utilized this strategy, also in the Sixth Meditation, where he wrote, The first observation I make at this point is that there is a great difference between the mind and the body, inasmuch as the body is by its very nature always divisible, while the mind is utterly indivisible. For when I consider the mind, or myself in so far as I am merely a thinking thing, I am unable to distinguish any parts within myself; I understand myself to be something quite single and complete. Although the whole mind seems to be united to the whole body, I recognize that if a foot or arm or any other part of the body is cut off, nothing has thereby been taken away from the mind. As for the faculties of willing, of understanding, of sensory perception and so on, these cannot be termed parts of the mind, since it is one and the same mind that wills, and understands and has sensory perceptions. By contrast, there is no corporeal or extended thing that I can think of which in my thought I cannot easily divide into parts; and this very fact makes me... (shrink)

Dominance hierarchies are ubiquitous in the societies of human and non-human animals. Evidence from comparative, developmental, and cognitive psychological investigations is presented that show how social dominance hierarchies shaped the evolution of the human mind, and hence, human social institutions. It is argued that the pressures that arise from living in hierarchical social groups laid a foundation of fundamental concepts and cognitive strategies that are crucial to surviving in social dominance hierarchies. These include recognizing and reasoning transitively about dominance relations, (...) fast-track learning of social norms (permissions, prohibitions, and obligations), detecting violations of social norms (cheating), monitoring reciprocal obligations, and reading the intentions of others.

The purpose of this paper is to set forth a sense in which programs can and do explain behavior, and to distinguish from this a number of senses in which they do not. Once we are tolerably clear concerning the sort of explanatory strategy being employed, two rather interesting facts emerge; (1) though it is true that programs are "internally represented," this fact has no explanatory interest beyond the mere fact that the program is executed; (2) programs which are couched (...) in information processing terms may have an explanatory interest for a given range of behavior which is independent of physiological explanations of the same range of behavior.

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)

It is commonly supposed that evolutionary explanations of cognitive phenomena involve the assumption that the capacities to be explained are both innate and modular. This is understandable: independent selection of a trait requires that it be both heritable and largely decoupled from other ”nearby’ traits. Cognitive capacities realized as innate modules would certainly satisfy these contraints. A viable evolutionary cognitive psychology, however, requires neither extreme nativism nor modularity, though it is consistent with both. In this paper, we seek to show (...) that rather weak assumptions about innateness and modularity are consistent with evolutionary explanations of cognitive capacities. Evolutionary pressures can affect the degree to which the development of a capacity is canalized by biasing acquisition/learning in ways that favor development of concepts and capacities that proved adaptive to an organism’s ancestors.

Two experiments were conducted to investigate children’s interpretations of standard arithmetic word problems and the factors that influence their interpretations. In Experiment 1, children were required to solve a series of problems and then to draw and select pictures that represented the problems’ structures. Solution performance was found to vary systematically with the nature of the representations drawn and chosen. The crucial determinant of solution success was the interpretation a child assigned to certain phrases used in the problems. In Experiment (...) 2, solution and drawing accuracy were found to be significantly improved by rewording problems to avoid ambiguous linguistic forms. Together, these results imply that (a) word-problem solution errors are caused by misinterpretations of certain verbal expressions commonly used in problem texts, and (b) these misinterpretations are the result of missing or inadequate mappings of these verbal expressions to partwhole knowledge.

One of the chief problems facing interpreters of Hume's philosophy is what I shall call the integration problem. It is a global problem inasmuch as it casts a shadow on every component of his philosophy, but does not directly affect how we interpret their details. The integration problem arises at the end of Book I of A Treatise of Human Nature, where Hume seemed to acknowledge that his account of human understanding, his logic, leads directly to total skepticism regarding both (...) everyday beliefs and abstruse thought. Nonetheless, he neither reconsidered and repudiated this virulent skepticism nor aborted and disowned his investigation of human nature, the project announced in the Introduction to the Treatise. Instead, he continues with Books II and III, neither of which dwells on or even acknowledges the skepticism with which Book I concludes. The resulting puzzle is not just about his decision to publish the three books as one work, since Hume appears paradoxically to endorse the triumph of skepticism and, yet, continue his pursuit of just the kind of knowledge the triumph of skepticism would entirely preclude. How, one is led to ask, can Hume consistently integrate the destructive skepticism of Book I with the constructive project of explaining and understanding human nature? It is not surprising that a wide range of proposals have been put forward by Hume scholars in response to this question. The crux of every such proposal is specifying how the skepticism of Book I is to be regarded. Is it genuine, a mere facade, or something in between? (shrink)

The publication of the Bradley review in the United Kingdom is a watershed in the development of policy regarding the way that the Criminal Justice System responds to individuals with mental health problems.

It has historically been assumed that comparative and superlative quantifiers can be semantically analysed in accordance with their core logical–mathematical properties. However, recent theoretical and experimental work has cast doubt on the validity of this assumption. Geurts & Nouwen have claimed that superlative quantifiers possess an additional modal component in their semantics that is absent from comparative quantifiers and that this accounts for the previously neglected differences in usage and interpretation between the two types of quantifier that they identify. Their (...) semantically modal hypothesis has received additional support from empirical investigations. In this article, we further corroborate that superlative quantifiers have additional modal interpretations. However, we propose an alternative analysis, whereby these quantifiers possess the semantics postulated by the classical model and the additional aspects of meaning arise as a consequence of psychological complexity and pragmatic implicature. We explain how this model is consistent with the existing empirical findings. Additionally, we present the findings of four novel experiments that support our model above the semantically modal account. (shrink)

I argue that Galileo regarded unaccelerated motion as requiring cause to sustain in. In an inclined plane experiment, the cause ceases when the incline ceases. When the incline ceases, what ceases is acceleration, not motion. Hence, unaccelerated motion requires no cause to sustain it.

The people's right to know and press rights to gather and publish information remain dominant justifications for controversial media activities.

This article also demonstrates moral justification of limits on (...) right to know and press freedom based on traditional ethics theories and media impact on public discourse. (shrink)

The purpose of the work reported here was to investigate the role of problem comparison and, specifically, analogical comparison in the induction of problem categories. This work was motivated by two factors. First, it is well-documented that experts and novices represent problems in very different ways and that solution success often depends on producing expert-like problem representations (DeGroot, 1965; Duncker, 1945; Chi, Feltovich, & Glaser, 1981; Hardiman, Dufresne, & Mestre, 1989; Novick, 1988; Schoenfeld & Herrmann, 1982; Silver, 1979, 1981). Second, (...) the problem representations produced by experts and novices appear to reflect differences in the way the two groups organize their knowledge bases. Although both groups appear to represent their problem-solving knowledge in terms of problem classes, or categories, expert categories tend to be defined in terms of deep structural features, whereas novice categories tend to be defined in terms of surface features (Adelson, 1981; Chase & Simon, 1973; Chi et al., 1981; Schoenfeld &. Herrmann, 1982; Silver, 1979, 1981). Because of this differential organization, experts are more likely than novices to retrieve solution-relevant information from their categories when constructing problem representations. (shrink)

D O N A L D D AV I D S O N’S “ Meaning and Truth,” re vo l u t i o n i zed our conception of how truth and meaning are related (Davidson    ). In that famous art i c l e , Davidson put forw a rd the bold conjecture that meanings are satisfaction conditions, and that a Tarskian theory of truth for a language is a theory of meaning for that language. (...) In “Meaning and Truth,” Davidson proposed only that a Tarskian truth theory is a theory of meaning. But in “Theories of Me a n i n g and Learnable Languages,” he argued that the finite base of a Tarskian theory, together with the now familiar combinatorics, would explain how a language with unbounded expre s s i ve capacity could be learned with finite means ( Davidson    ). This certainly seems to imply that learning a language is, in p a rt at least, learning a Tarskian truth theory for it, or, at least, learning what is specified by such a theory. Davisdon was cagey about committing to the view that meanings actually a re satisfaction conditions, but subsequent followers had no such scru p l e s . We can sum this up in a trio of claims: Davidson’s Conjecture () A theory of meaning for L is a truth-conditional semantics for L. () To know the meaning of an expression in L is to know a satisfaction condition for that expression. () Meanings are satisfaction conditions. For the most part, it will not matter in what follows which of these claims is at stake. I will simply take the three to be different ways of formulating what I will call Davidson’s Conjecture (or sometimes just The Conjecture). Davidson’s Conjecture was a very bold conjecture.

Pregnancy care is chargeable for migrants who do not have indefinite leave to remain in the UK. Women who are not ‘ordinarily resident’, including prospective asylum applicants, some refused asylum-seekers, unidentified victims of trafficking and undocumented people are required to pay substantial charges in order to access antenatal, intrapartum and postnatal services as well as abortion care within the National Health Service. In this paper, we consider the ethical issues generated by the exclusion of pregnancy care from the raft of (...) services which are free to all. We argue that charging for pregnancy care amounts to sex discrimination, since without pregnancy care, sex may pose a barrier to good health. We also argue that charging for pregnancy care violates bodily autonomy, entrenches the sex asymmetry of sexual responsibility, centres the male body and produces health risks for women and neonates. We explore some of the ideological motivations for making maternity care chargeable, and suggest that its exclusion responds to xenophobic populism. We recommend that pregnancy care always be free regardless of citizenship or residence status, and briefly explore how these arguments bear on the broader moral case against chargeable healthcare for migrants.
