Many philosophers of science believe that empirical psychology can contribute little to the philosophical investigation of explanations. They take this to be shown by the fact that certain explanations fail to elicit any relevant psychological events (e.g., familiarity, insight, intelligibility, etc.). We report results from a study suggesting that, at least among those with extensive science training, a capacity to render an event intelligible is considered a requirement for explanation. We also investigate for whom explanations must be capable of rendering (...) events intelligible and whether or not accuracy is also viewed as a requirement. (shrink)

Summary. The viability of the proposal that human cognition involves the utilization of nonsentential models is seriously undercut by the fact that no one has yet given a satisfactory account of how neurophysiological circuitry might realize representations of the right sort. Such an account is offered up here, the general idea behind which is that high-level models can be realized by lower—level computations and, in turn, by neural machinations. It is shown that this account can be usefully applied to deal (...) with problems in fields ranging from artificial intelligence to the philosophy of science. (shrink)

Jonathan Walkan challenges cognitive science's dominant model of mental representation and proposes a novel, well-devised alternative. The traditional view in the cognitive sciences uses a linguistic model of mental representation. That logic-based model of cognition informs and constrains both the classical tradition of artificial intelligence and modeling in the connectionist tradition. It falls short, however, when confronted by the frame problem---the lack of a principled way to determine which features of a representation must be updated when new information becomes (...) available. So far, proposed alternatives, including the imagistic model, have not resolved the problem. Waskan proposes the Intrinsic Cognitive Models hypothesis, according to which representational states can be concpetualized as the cognitive equivalent of scale models.Waskan argues further that the proposal that humans harbor and manipulate cognitive counterparts to scale models offers the only viable explanation for what most clearly differentiates humans from other creatures: the capacity to engage in truth-preserving manipulation of representations. The ICM hypothesis, he claims, can be distinguished from sentence-based accounts of truth preservation in a way that is fully compatible with what is known about the brain. (shrink)

Many philosophers of science follow Hempel in embracing both substantive and methodological anti-psychologism regarding the study of explanation. The former thesis denies that explanations are constituted by psychological events, and the latter denies that psychological research can contribute much to the philosophical investigation of the nature of explanation. Substantive anti-psychologism is commonly defended by citing cases, such as hyper-complex descriptions or vast computer simulations, which are reputedly generally agreed to constitute explanations but which defy human comprehension and, as a result, (...) fail to engender any relevant psychological events. It is commonly held that the truth of the substantive thesis would lend support to the methodological thesis. However, the standard argument for the substantive thesis presumes that philosophers’ own judgments about the aforementioned cases issues from mastery of the lay or scientific norms regarding the use of ‘explanation.’ Here we challenge this presumption with a series of experiments indicating that both lay and scientific populations require of explanations that they actually render their targets intelligible. This research not only undermines a standard line of argument for substantive anti-psychologism, it demonstrates the utility of psychological research methods for answering meta-questions about the norms regarding the use of ‘explanation.’.

Resurgent interest in both mechanistic and counterfactual theories of explanation has led to a fair amount of discussion regarding the relative merits of these two approaches. James Woodward is currently the pre-eminent counterfactual theorist, and he criticizes the mechanists on the following grounds: Unless mechanists about explanation invoke counterfactuals, they cannot make sense of claims about causal interactions between mechanism parts or of causal explanations put forward absent knowledge of productive mechanisms. He claims that these shortfalls can be offset if (...) mechanists will just borrow key tenets of his counterfactual theory of causal claims. What mechanists must bear in mind, however, is that by pursuing this course they risk both the assimilation of the mechanistic theories of explanation into Woodward’s own favored counterfactual theory, and they risk the marginalization of mechanistic explanations to a proper subset of all explanations. An outcome more favorable to mechanists might be had by pursuing an actualist-mechanist theory of the contents of causal claims. While it may not seem obvious at first blush that such an approach is workable, even in principle, recent empirical research into causal perception, causal belief, and mechanical reasoning provides some grounds for optimism. (shrink)

Here I consider the relative merits of two recent models of explanation, James Woodward's interventionist-counterfactual model and the model model. According to the former, explanations are largely constituted by information about the consequences of counterfactual interventions. Problems arise for this approach because countless relevant interventions are possible in most cases and because it overlooks other kinds of equally relevant information. According the model model, explanations are largely constituted by cognitive models of actual mechanisms. On this approach, explanations tend not to (...) represent any of the aforementioned information explicitly but can instead be used to produce it on demand. The model model thus offers the more plausible account of the information of which we are aware when we have an explanation and of the ratiocinative process through which we derive many kinds of information that are relevant to the evaluation of explanations. (shrink)

Much of the philosophical discussion of explanations has centered around two broad conceptions of what sorts of ‘things’ explanations are – namely, the descriptive and ontic conceptions. Defenders of each argue that scientific psychology has at best little to contribute to the study of explanations. These anti-psychologistic arguments come in two main varieties, the metaphysical and the epistemic. Both varieties trace back to Hempel and recur in the more recent writings of prominent mechanists. The metaphysical arguments attempt to combat psychologism (...) about explanation by doubly dissociating explanations themselves from the commonly associated phenomenology of explanation. The epistemic arguments attempt to combat psychologism by doubly dissociating the good-making features of explanations from the CAPE. I focus on the metaphysical arguments here, for only they directly concern the nature of, as opposed to the evaluation conditions for, explanations. The metaphysical arguments are all shown to equivocate over ‘explanation’, and thus they are no threat to the proposal that sometimes explanations just are psychological events. Such arguments do, nonetheless, gesture towards something important – namely, that the CAPE is neither necessary nor sufficient for explanation in any sense. Similar considerations lead another latter-day mechanist to conclude that no phenomenology of any sort is essential for explanation. What all of these thinkers overlook, however, is that there is another important phenomenological correlate of explanation – namely, finding a happening intelligible or understanding how or why-possibly – and it may well be of the very essence of explanation, at least in the psychological sense. I propose a psychomechanistic theory of intelligibility that accounts for how we can, through finite means, make boundless, endlessly qualified inferences about the implications of our explanations. In closing I note that, although finding a happening intelligible does sometimes engender an unjustified confidence in correctness, we should not overlook how attaining this state does at least put us in a kind of epistemic base camp. I also hint at how intelligibility could turn out to be the ultimate source of the descriptive and ontic conceptions of explanation. (shrink)

Theories concerning the structure, or format, of mental representation should (1) be formulated in mechanistic, rather than metaphorical terms; (2) do justice to several philosophical intuitions about mental representation; and (3) explain the human capacity to predict the consequences of worldly alterations (i.e., to think before we act). The hypothesis that thinking involves the application of syntax-sensitive inference rules to syntactically structured mental representations has been said to satisfy all three conditions. An alternative hypothesis is that thinking requires the construction (...) and manipulation of the cognitive equivalent of scale models. A reading of this hypothesis is provided that satisfies condition (1) and which, even though it may not fully satisfy condition (2), turns out (in light of the frame problem) to be the only known way to satisfy condition (3).

I have argued elsewhere that non-sentential representations that are the close kin of scale models can be, and often are, realized by computational processes. I will attempt here to weaken any resistance to this claim that happens to issue from those who favor an across-the-board computational theory of cognitive activity. I will argue that embracing the idea that certain computers harbor nonsentential models gives proponents of the computational theory of cognition the means to resolve the conspicuous disconnect between the sentential (...) character of the data structures they posit and the nonsentential qualitative character of our perceptual experiences of corporeal (i.e., spatial, kinematic, and dynamic) properties. Along the way, I will question the viability of some externalist remedies for this disconnect, and I will explain why the computational theory put forward here falls quite clearly beyond the useful bounds of the Chinese-Room argument.

We humans often respond effectively when faced with novel circumstances. This is because we are able to predict how particular alterations to the world will play out. Philosophers, psychologists, and computational modelers have long favored an account of this process that takes its inspiration from the truth-preserving powers of formal deduction techniques. There is, however, an alternative hypothesis that is better able to account for the human capacity to predict the consequences worldly alterations. This alternative takes its inspiration from the (...) powers of truth preservation exhibited by scale models and leads to a determinate computational solution to the frame problem. (shrink)

Cognitive Science is a major new guide to the central theories and problems in the study of the mind and brain. The authors clearly explain how and why cognitive science aims to understand the brain as a computational system that manipulates representations. They identify the roots of cognitive science in Descartes - who argued that all knowledge of the external world is filtered through some sort of representation - and examine the present-day role of Artificial Intelligence, computing, psychology, linguistics and (...) neuroscience. Throughout, the key building blocks of cognitive science are clearly illustrated: perception, memory, attention, emotion, language, control of movement, learning, understanding and other important mental phenomena. Cognitive Science: presents a clear, collaborative introduction to the subject is the first textbook to bring together all the different strands of this new science in a unified approach includes illustrations and exercises to aid the student.

Sentience is the capacity to have feelings, such as feelings of pain, pleasure, hunger, thirst, warmth, joy, comfort and excitement. It is not simply the capacity to feel pain, but feelings of pain, distress or harm, broadly understood, have a special significance for animal welfare law. Drawing on over 300 scientific studies, we evaluate the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid and cuttlefish) and the decapod crustaceans or, (...) for short, decapods (including crabs, lobsters and crayfish). We also evaluate the potential welfare implications of current commercial practices involving these animals. (shrink)

This editorial introduces the Journal of Consciousness Studies special issue on "Animal Consciousness". The 15 contributors and co-editors answer the question "How should we study animal consciousness scientifically?" in 500 words or fewer.

In a new study, Ben-Haim et al. use subliminal stimuli to separate conscious and unconscious perception in macaques. A programme of this type, using a range of cognitive tasks, is a promising way to look for conscious perception in more controversial cases.

Featuring the work of both established and up-and-coming scholars, this collection takes stock of the recent turn towards religion in political theory, identifying unresolved challenges and suggesting new avenues for theoretical inquiry.

We consider the relationship between neural and behavioural evidence for animal consciousness. We critically examine two recent studies: one neural and one behavioural. The first, on crows, finds different neural activity depending on whether a stimulus is reported as seen or unseen. However, to implicate this neural activity in consciousness, we must assume that a specific conditioned behaviour is a report of conscious experience. The second study, on macaques, records behaviours strikingly similar to patterns of conscious and unconscious perception in (...) humans. However, confounds are only ruled out in human subjects, presupposing substantial neural similarity between humans and macaques. Taken together, the two studies reveal a sense in which neural and behavioural research rely on each other. Looking ahead, these two types of evidence could prove to be either mutually reinforcing or mutually undermining. The science of animal consciousness needs both neural and behavioural evidence, ideally obtained as part of a single coordinated programme. (shrink)

The aesthetics of everyday life, originally developed by Henri Lefebvre and other modernist theorists, is an extension of traditional aesthetics, usually confined to works of art. It is not limited to the study of humble objects but is rather concerned with all of the undeniably aesthetic experiences that arise when one contemplates objects or performs acts that are outside the traditional realm of aesthetics. It is concerned with the nature of the relationship between subject and object. One significant aspect of (...) everyday aesthetics is environmental aesthetics, whether constructed, as a building, or manipulated, as a landscape. Others, also discussed in the book, include sport, weather, smell and taste, and food. (shrink)

The renewed interest in the issue of black reparations, both in the public sphere and among scholars, is a welcome development because the racial injustices of the past continue to shape American society by disadvantaging African Americans in a variety of ways. Attention to the past and how it has shaped present-day inequality seems essential both to understanding our predicament and to justifying policies that would address and undermine racial inequality. Given this, any argument for policies designed to pursue racial (...) justice must be, at least in part, backward-looking, justifi ed partly as compensation for the effects of the wrongs of the past. However, some arguments about black reparations, both pro and con, are focused too far in the past. An unspoken assumption of much of the debate about black reparations is that these would be reparations for slavery. This, we argue, is a mistake. Racial inequality in the United States today may, ultimately, be based on slavery, but it is also based on the failure of the country to take effective steps since slavery to undermine the structural racial inequality that slavery put in place. From the latter part of the nineteenth century through the fi rst half of the twentieth century, the Jim Crow system continued to keep Blacks “in their place,” and even during and after the civil rights era no policies were adopted to dismantle the racial hierarchy that already existed. An important part of the story of racial inequality today is the history of housing and lending discrimination in the second half of the twentieth century (McCarthy 2002; 2004). Home equity, for many Americans, is a very important source of wealth, and the decades after World War II were ones of rapid home equity growth. They were the decades that saw the creation of a large, mostly suburban, middle class. But the middle class that was created was also mostly White, and this was due largely to government policies that (in many cases intentionally) excluded Blacks from the opportunities to get into the home market and benefi t from home equity growth. In this paper we argue that recent housing and lending discrimination constitutes an important basis for black reparations.. (shrink)

The sentence "The boss fired the employee who is always late" invites the defeasible inference that the speaker is attempting to convey that the lateness caused the firing. We argue that such inferences cannot be understood in terms of familiar approaches to extrasemantic enrichment such as implicature, impliciture, explicature, or species of local enrichment already in the literature. Rather, we propose that they arise from more basic cognitive strategies, grounded in processes of coherence establishment, that thinkers use to make sense (...) of the world. Attention to such cases provides a richer and more varied landscape of extrasemantic enrichment than has been appreciated to date. (shrink)

Madole & Harden argue that just as the results of randomized controlled trials (RCTs) represent gains in causal knowledge and are useful, despite their limitations, so too are the findings of human behavior genetics. We argue that this analogy is misleading. Unlike RCTs, the results of human behavior genetics research cannot suggest efficacious interventions, nor point toward future research.

There is societal consensus that cancer clinical trial participation is unjust because some sociodemographic groups have been systematically underrepresented. Despite this, neither a definition nor an ethical explication for the justice norm of equity has been clearly articulated in this setting, leading to confusion over its application and goals. Herein we define equity as acknowledging sociodemographic circumstances and apportioning resource and opportunity allocation to eliminate disparities in outcomes, and we explore the issues and tensions this norm generates through practical examples. (...) We assess how equality-based enrollment structures in clinical cancer research have perpetuated historical disparities and what equity-based alternatives are necessary to achieve representativeness and an expansive conception of participatory justice in clinical cancer research. This framework addresses the breadth from normative to applied by defining the justice norm of equity and translating it into practical strategies for addressing participation disparities in clinical cancer research.

An important goal of teaching ethics to engineering students is to enhance their ability to make well-reasoned ethical decisions in their engineering practice: a goal in line with the stated ethical codes of professional engineering organizations. While engineering educators have explored a wide range of methodologies for teaching ethics, a satisfying model for developing ethical reasoning skills has not been adopted broadly. In this paper we argue that a principlist-based approach to ethical reasoning is uniquely suited to engineering ethics education. (...) Reflexive Principlism is an approach to ethical decision-making that focuses on internalizing a reflective and iterative process of specification, balancing, and justification of four core ethical principles in the context of specific cases. In engineering, that approach provides structure to ethical reasoning while allowing the flexibility for adaptation to varying contexts through specification. Reflexive Principlism integrates well with the prevalent and familiar methodologies of reasoning within the engineering disciplines as well as with the goals of engineering ethics education.

An anthropocentric scope for clinical medical ethics (CME) has largely separated this area of bioethics from environmental concerns. In this article, we first identify and reconcile the ethical issues imposed on CME by climate change including the dispersion of related causes and effects, the transdisciplinary and transhuman nature of climate change, and the historic divorce of CME from the environment. We then establish how several moral theories undergirding modern CME, such as virtue ethics, feminist ethics, and several theories of justice, (...) promote both a flourishing of human medical practice and the environment. We conclude by defining an expanded the scope of CME as inclusive of not only patients, families, physicians, and other health professionals but other humans, non-humans, and their shared environment. We then apply this scope and theory to a widely used framework for applying CME, the Four Topics model, to construct a climate conscious approach to CME. (shrink)

The National Health Service (NHS) in the UK is currently facing a significant waiting list backlog following the disruption of the COVID-19 pandemic, with millions of patients waiting for elective surgical procedures. Effective treatment prioritisation has been identified as a key element of addressing this backlog, with NHS England's delivery plan highlighting the importance of ensuring that those with ‘the clinically most urgent conditions are diagnosed and treated most rapidly’. Indeed, we describe how the current clinical guidance on prioritisation issued (...) by The Federation of Surgical Specialty Associations serves this aim. However, whilst there are strong reasons to prioritise elective surgery in accordance with clinical need, we argue that it would be a mistake to assume that prioritisation in accordance with clinical need requires only a clinical or scientific judgement. The understanding of clinical need that we choose to employ in a prioritisation system will be grounded by some key ethical judgements. Moreover, we may also have to make trade-offs between addressing clinical need, safeguarding equality, and achieving other benefits. As the UK faces up to the backlog, it is important that surgical prioritisation guidelines enshrine a broad range of values that we believe ought to determine access to care in non-emergency circumstances. Our analysis suggests that the current approach to prioritisation is not a sufficiently nuanced way of balancing the different moral values that are operative in this context. (shrink)

Behrendt & Young's (B&Y's) novel “unifying model” of hallucinations, although comprehensive, fails to incorporate research into the possible role of 5-HT2A receptors in the mode of action of novel “atypical” antipsychotic drugs (which treat hallucinations effectively), and into the role of such receptors, which are located in thalamocortical circuits, in mediating drug-induced hallucinations.

The potential to instrumentalize drug use based upon the detection of very many different drug states undoubtedly exists, and such states may play a role in psychiatric and many other drug uses. Nevertheless, nonaddictive drug use is potentially more parsimoniously explained in terms of sensation seeking/impulsivity and drug expectations. Cultural factors also play a major role in nonaddictive drug use.

Our thesis in this paper is that consideration of Wright’s account of what it is to be judgement-dependent leads us to the conclusion that teaching is judgement dependent. We begin with a consideration of Wright’s account of what it is to be judgement-dependent. We then make the case that teaching satisfies the conditions on what it is to be judgement-dependent. Our intention is not to delve into the independent plausibility of such a view. Our focus is simply on showing the (...) connection between Wright’s account of judgement-dependence and what it is to teach. (shrink)

When interpreting a sentence such as Every time the company fires an employee who comes in late, a union complaint is lodged, an addressee is likely to infer that the union will only complain when an employee is fired because he came in late. One is thus led to ask why a purely pragmatic enrichment of this sort -- one drawn despite no risk of interpretative failure nor other linguistic mandate -- would intrude upon truth conditions. We argue that this (...) effect results from the interaction among three pragmatic phenomena: presupposition, the associative mechanisms that underlie the establishment of coherence in discourse, and the calculation of domain restriction for quantificational operators. Because the analysis does not consider the operative enrichments to be species of implicature, we claim that such cases do not represent an intrusion of implicature into truth-conditional content. Instead, they merely involve the context-dependent determination of quantificational domains. (shrink)

We accept Sunstein's claim that people often use moral heuristics to make judgments and decisions. However, in situations that include a risk of betrayal, we disagree with Sunstein about when the relevant moral heuristic may be said to “misfire.” We suggest that the moral heuristic people apply to avoid the possibility of safety-product betrayal may be reasonable.

The inaugural collection in an exciting new exchange between philosophers and geographers, this volume provides interdisciplinary approaches to the environment as space, place, and idea. Never before have philosophers and geographers approached each other's subjects in such a strong spirit of mutual understanding. The result is a concrete exploration of the human-nature relationship that embraces strong normative approaches to environmental problems.
