Contemporary psychologism has been amended for most of the objections by its opponents over a century ago. However, some authors still raise doubts about its ability to account for some peculiar properties of logic. In particular, it is argued that the psychological universality of patterns of inferential behavior is not sufficient to account for the normativity of logic. In this paper, I deal with the issue and offer three alternative solutions that do not rely on mere empirical universality. I will (...) use the works of Laurence Jonathan Cohen, Diego Marconi and Marcello D'Agostino, adapting them for the purpose of defending logical psychologism. I will therefore argue that, although more refined work on the subject is needed, contemporary psychologism has the key resources to retain its place in the philosophical debate on the foundations of logic.

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)

Decision theory requires agents to assign probabilities to states of the world and utilities to the possible outcomes of different actions. When agents commit to having the probabilities and/or utilities in a decision problem defined by objective features of the world, they may find themselves unable to decide which actions maximize expected utility. Decision theory has long recognized that work-around strategies are available in special cases; this is where dominance reasoning, minimax, and maximin play a role. Here we describe a (...) different work around, wherein a rational decision about one decision problem can be reached by ‘interpolating’ information from another problem that the agent believes has already been rationally solved.

Molyneux asked whether a newly sighted person could distinguish a sphere from a cube by sight alone, given that she was antecedently able to do so by touch. This, we contend, is a question about general ideas. To answer it, we must ask (a) whether spatial locations identified by touch can be identified also by sight, and (b) whether the integration of spatial locations into an idea of shape persists through changes of modality. Posed this way, Molyneux’s Question goes substantially (...) beyond question (a), about spatial locations, alone; for a positive answer to (a) leaves open whether a perceiver might cross-identify locations, but not be able to identify the shapes that collections of locations comprise. We further emphasize that MQ targets general ideas so as to distinguish it from corresponding questions about experiences of shape and about the property of tangible (vs. visual) shape. After proposing a generalized formulation of MQ, we extend earlier work (“Many Molyneux Questions,” Australasian Journal of Philosophy 2020) by showing that MQ does not admit a single answer across the board. Some integrative data-processes transfer across modalities; others do not. Seeing where and how such transfer succeeds and fails in individual cases has much to offer to our understanding of perception and its modalities. (shrink)

In this paper I reply to two sets of criticisms—a first from Joshua Gert, and a second from Keith Allen—of the relationalist view of color developed and defended in my book, The Red and the Real: An Essay on Color Ontology.

Locates, discusses, and explains the transition between Nietzsche's middle and late periods represented by the first four books of _The Gay Science_.

Molyneux's Question (MQ) concerns whether a newly sighted man would recognize/distinguish a sphere and a cube by vision, assuming he could previously do this by touch. We argue that (MQ) splits into questions about (a) shared representations of space in different perceptual systems, and about (b) shared ways of constructing higher dimensional spatiotemporal features from information about lower dimensional ones, most of the technical difficulty centring on (b). So understood, MQ resists any monolithic answer: everything depends on the constraints faced (...) by particular perceptual systems in extracting features of higher dimensionality from those of lower. Each individual question of this type is empirical and must be investigated separately. We present several variations on MQ based on different levels of dimensional integration—some of these are familiar, some novel adaptations of problems known elsewhere, and some completely novel. Organizing these cases in this way is useful because it unifies a set of disparate questions about intermodal transfer that have held philosophical and psychological interest, suggests a new range of questions of the same type, sheds light on similarities and differences between members of the family, and allows us to formulate a much-augmented set of principles and questions concerning the intermodal transfer of spatiotemporal organization.

Significant variations in the way objects appear across different viewing conditions pose a challenge to the view that they have some true, determinate color. This view would seem to require that we break the symmetry between multiple appearances in favor of a single variant. A wide range of philosophical and non-philosophical writers have held that the symmetry can be broken by appealing to daylight viewing conditions—that the appearances of objects in daylight have a stronger, and perhaps unique, claim to reveal (...) their true colors. In this note we argue that, whatever else its merits, this appeal to daylight is not a satisfactory answer to the problem posed by perceptual variation. (shrink)

According to many philosophers, psychological explanation canlegitimately be given in terms of belief and desire, but not in termsof knowledge. To explain why someone does what they do (so the common wisdom holds) you can appeal to what they think or what they want, but not what they know. Timothy Williamson has recently argued against this view. Knowledge, Williamson insists, plays an essential role in ordinary psychological explanation.Williamson's argument works on two fronts.First, he argues against the claim that, unlike knowledge, (...) belief is``composite'' (representable as a conjunction of a narrow and a broadcondition). Belief's failure to be composite, Williamson thinks, undermines the usual motivations for psychological explanation in terms of belief rather than knowledge.Unfortunately, we claim, the motivations Williamson argues against donot depend on the claim that belief is composite, so what he saysleaves the case for a psychology of belief unscathed.Second, Williamson argues that knowledge can sometimes provide abetter explanation of action than belief can.We argue that, in the cases considered, explanations that cite beliefs(but not knowledge) are no less successful than explanations that citeknowledge. Thus, we conclude that Williamson's arguments fail both coming andgoing: they fail to undermine a psychology of belief, and they fail tomotivate a psychology of knowledge. (shrink)

In an intriguing essay, G. A. Cohen has defended a conservative bias in favour of existing value. In this paper, we consider whether Cohen’s conservatism raises a new challenge to the use of human enhancement technologies. We develop some of Cohen’s suggestive remarks into a new line of argument against human enhancement that, we believe, is in several ways superior to existing objections. However, we shall argue that on closer inspection, Cohen’s conservatism fails to offer grounds (...) for a strong sweeping objection to enhancement, and may even offer positive support for forms of enhancement that preserve valuable features of human beings. Nevertheless, we concede that Cohen’s arguments may suggest some plausible and important constraints on the modality of legitimate and desirable enhancements. (shrink)

Facts about justification are not brute facts. They are epistemic facts that depend upon more fundamental non-epistemic facts. Internalists about justification often argue for mentalism, which claims that facts about justification supervene upon one’s non-factive mental states, using Lehrer and Cohen’s :191–207, 1983) New Evil Demon Problem. The New Evil Demon Problem tells you to imagine yourself the victim of a Cartesian demon who deceives you about what the external world is like, and then asks whether you nevertheless have (...) justification for your beliefs about the external world. Internalists and externalists agree that there is something that is epistemically good or valuable about both your actual beliefs and your beliefs in the demon scenario. Internalists claim that the epistemic property which these sets of beliefs share most intuitively should be thought of as sameness of justification. Externalists, on the other hand, reject this claim, usually either by challenging the internalist intuition directly, or by arguing that there is a more plausible way to think about the epistemic property in question. Recently, both kinds of externalist objection have been raised against the argument from the New Evil Demon Problem for mentalism. The goal of this paper is to defend the argument against three prominent objections—a pair of which is offered by Littlejohn :399–434, 2009) and one by Williamson Rationality and the good: critical essays on the ethics and epistemology of Robert Audi, Oxford University Press, Oxford, 2007; in: Dutant J, Dohrn D The new evil demon, Oxford University Press, Oxford, 2016).

“Bioconservatives” in the human enhancement debate endorse the conservative claim that we should reject the use of biotechnologies that enhance natural human capacities. However, they often ground their objections to enhancement with contestable claims about human nature that are also in tension with other common tenets of conservatism. We argue that bioconservatives could raise a more plausible objection to enhancement by invoking a strain of conservative thought developed by G.A. Cohen. Although Cohen’s conservatism is not sufficient to fully (...) revive the bioconservative objection, we argue that it can be supplemented by an account of reasonable partiality for humanity in a way that provides further support to the bioconservative position in a manner congruous with broader conservatism. We propose that the idea of partiality to humanity can buttress the bioconservative objection into its strongest possible form. However, we conclude by arguing that, even in this form, the objection cannot do all the work that bioconservatives expect of it. (shrink)

Kendall Walton argues that photographs, like mirrors and microscopes, meet sufficient conditions to be considered a kind of prosthesis for seeing. Well aware of the controversiality of this claim, he offers three criteria for perception met by photographs like other perceptual aids which makes them transparent –that is, we see through them.1(II) Jonathan Cohen and Aaron Meskin attempt to refute the transparency thesis by arguing that photographs cannot be genuine prostheses for seeing because they fail to meet another (...) necessary condition, namely that of egocentric spatial information (ESI). Only devices that belong to a process type that carries ESI are, in principle, genuine prostheses for seeing.2 (III) I will offer a two- part refutation of the proposed disqualification of photographs by 1) offering an example of a case where another instance of the process-type to which photographs belong carries ESI, establishing the reliability of the process type that allegedly precluded photographs from qualifying (IV) and 2) offering another example to illustrate how photographs can meet the ESI condition.

In a widely read essay, “For the Law, Neuroscience Changes Nothing and Everything,” Joshua Greene and Jonathan Cohen argue that the advance of neuroscience will result in the widespread rejection of free will, and with it – of retributivism. They go on to propose that consequentialist reforms are in order, and they predict such reforms will take place. We agree that retributivism should be rejected, and we too are optimistic that rejected it will be. But we don’t think (...) that such a development will have much to do with neuroscience – it won’t, because neuroscience is unlikely to show that we have no free will. We have two main aims in this paper. The first is to rebut various aspects of the case against free will. The second is to examine the case for consequentialist reforms. We take Greene and Cohen’s essay as a hobbyhorse, but our criticisms are applicable to neurodeterministic anti-free-willism in general. We first suggest that Greene and Cohen take proponents of free will to be committed to an untenable homuncular account of agency. But proponents of free will can dispense with such a commitment. In fact, we argue, it is Greene and Cohen who work with an overly simple account of free will. We sketch a more nuanced conception. We then turn to the proposal for consequentialist reforms. We argue that retributivism will fall out of favor not as a consequence of neuroscience-driven rejection of free will, but rather, as a result of a familiar feature of moral progress – the expanding circle of concern. In short, retributivism can and must die, but neuroscience will not kill it – humanity will. (shrink)

I defend external world realism. I assume that the principle of inference to the best explanation is justified: roughly, a hypothesis that provides a better explanation of the total evidence is more probable than one that does not. I argue that the existence of a world of spatial objects provides a systematic explanation of the spatial contents of visual experience, and that it provides a better explanation than traditional skeptical hypotheses. This paper thus pursues the explanationist strategy of Laurence (...) BonJour and Jonathan Vogel. It is an improved, more compelling defense, for at least two reasons. First, the attention to spatial properties, and in particular to what I call perspectival projections, makes the explanatory power of the realist hypothesis much more vivid and concrete. Second, the argument preserves and elucidates much that seems correct in the explanationist arguments others have offered while avoiding significant problems and shortcomings. (shrink)

I am deeply indebted to Alex Byrne, Jonathan Cohen and Matthew McGrath for their careful, constructive, and penetrating comments on The Unity of Perception and I am grateful for the opportunity to clarify my view further.

In this paper I propose an account of representation for scientific models based on Kendall Walton’s ‘make-believe’ theory of representation in art. I first set out the problem of scientific representation and respond to a recent argument due to Craig Callender and Jonathan Cohen, which aims to show that the problem may be easily dismissed. I then introduce my account of models as props in games of make-believe and show how it offers a solution to the problem. Finally, (...) I demonstrate an important advantage my account has over other theories of scientific representation. All existing theories analyse scientific representation in terms of relations, such as similarity or denotation. By contrast, my account does not take representation in modelling to be essentially relational. For this reason, it can accommodate a group of models often ignored in discussions of scientific representation, namely models which are representational but which represent no actual object.

This paper critically examines color relationalism and color relativism, two theories of color that are allegedly supported by variation in normal human color vision. We mostly discuss color relationalism, defended at length in Jonathan Cohen's The Red and the Real, and argue that the theory has insuperable problems.

Deductive Cogency holds that the set of propositions towards which one has, or is prepared to have, a given type of propositional attitude should be consistent and closed under logical consequence. While there are many propositional attitudes that are not subject to this requirement, e.g. hoping and imagining, it is at least prima facie plausible that Deductive Cogency applies to the doxastic attitude involved in propositional knowledge, viz. belief. However, this thought is undermined by the well-known preface paradox, leading a (...) number of philosophers to conclude that Deductive Cogency has at best a very limited role to play in our epistemic lives. I argue here that Deductive Cogency is still an important epistemic requirement, albeit not as a requirement on belief. Instead, building on a distinction between belief and acceptance introduced by Jonathan Cohen and recent developments in the epistemology of understanding, I propose that Deductive Cogency applies to the attitude of treating propositions as given in the context of attempting to understand a given phenomenon. I then argue that this simultaneously accounts for the plausibility of the considerations in favor of Deductive Cogency and avoids the problematic consequences of the preface paradox. (shrink)

In November 2003, the University of Fribourg hosted a symposium on the ontology of colors. The invited participants included Justin Broackes, Alex Byrne, David Chalmers, Larry Hardin, Joe Levine and Barry Maund. The points of view presented by the participants in their thought-provoking papers were highly divergent. The presentation of each paper was followed by a long and intense discussion. Despite the divergence of the views proposed, the discussion during the symposium was highly focused. Several specific issues came up repeatedly (...) in the debate and illuminated the puzzle about the nature of colors in a thought provoking way from different angles. We include these papers in our brief description in the present introduction to present to the reader all the different viewpoints that have nourished the debate throughout the symposium. We are glad to be able to include one further invited paper by Jonathan Cohen in the present volume. In an attempt to transfer some of the atmosphere of the meeting to the reader and in order to make this collection still more stimulating we invited each participant to contribute comments on the other papers.

En este trabajo se discute acerca de la posibilidad de llevar a cabo afirmaciones epistémicamente objetivas respecto del arte a partir de la filosofía de la sociedad de John Searle y de la epistemología del desacuerdo. Para ello se considerarán las distinciones ontológicamente objetivo/subjetivo y epistémicamente objetivo/subjetivo en relación con el arte como fenómeno relativo a la intencionalidad, señalándolo como ontológicamente subjetivo y epistémicamente objetivo. Luego se discutirá acerca del desacuerdo en torno a obras polémicas de arte y de la (...) disolución de tales desacuerdos al considerar la oposición entre creencia y aceptación según la propuesta de Jonathan Cohen. Finalmente, mostrando la posibilidad de generar acuerdos en torno al juicio de gustos, se señala el rol de las instituciones relativas al arte en nuestra comprensión del estatuto artístico de las obras polémicas. De esta manera, se pretende señalar que la apreciación de una obra como ‘arte’ es una cuestión objetiva dependiente de las instituciones que operan en nuestra sociedad. (shrink)

Is there a place in scientific inquiry for guessing? Jonathan Cohen has recently argued that resorting to guesswork entails a loss of objectivity and regard for evidence which are essential to proper scientific investigation. I assess the merits of Cohen’s view first by taking as a test case Aristotle’s positive view of the role of guesswork (anchinoia) and conjecture (eustochia) in the search for the connections essential to the construction of scientific demonstrations. I then argue contra (...) class='Hi'>Cohen that one can usefully employ guesswork while also employing reason; that it is possible to guess either intelligently or mindlessly; and consequently, that the use of guesswork need not represent a diminution in respect for the objectivity essential to scientific investigation. Although I would not claim that guesswork has a role to play in all scientific inquiry, there appear to be some datable instances of the useful and respectable scientific guess. (shrink)

The field of textbooks in philosophy of mind is a crowded one. I shall consider six recent texts for their pedagogical usefulness. All have been published within the last five years, though two are new editions of previously published books. The first three are authored monographs: by K. T. Maslin, Barbara Montero, and André Kukla and Joel Walmsley. I then review three anthologies, each with two editors: William Lycan and Jesse Prinz, Brie Gertler and Lawrence Shapiro, and Brian McLaughlin and (...) Jonathan Cohen. These six texts constitute a diverse bunch. Within each of the two groups (monographs and anthologies), each individual text differs significantly from the other two in its approach, scope, and thus suitability for various levels of teaching.

This paper argues for a methodological point that bears on a relatively long-standing debate concerning collective beliefs in the sense elaborated by Margaret Gilbert: are they cases of belief or rather of acceptance? It is argued that epistemological accounts and distinctions developed in individual epistemology on the basis of considering the individual case are not necessarily applicable to the collective case or, more generally, uncritically to be adopted in collective epistemology.

I consider what prima facie attractive communitarian ethical perspectives salient among indigenous African peoples entail for distributive justice within a state, and I argue that they support a form of economic egalitarianism that differs in several important ways from varieties common in contemporary Anglo-American political philosophy. In particular, the sort of economic egalitarianism I advance rivals not only luck-oriented variants from the likes of Ronald Dworkin, G. A. Cohen and theorists inspired by them such as Richard Arneson, Carl Knight (...) and Nir Eyal, but also more ‘social’ kinds advocated by Elizabeth Anderson, Samuel Scheffler and Jonathan Wolff. Although I do not argue that these broadly Kantian egalitarianisms are less plausible than the Afro-communitarian version, I do aim to establish that it should be taken as seriously as they, at this stage of the debate.

This introductory chapter provides an overview of the recent debate about responsibility and distributive justice. It traces the recent philosophical focus on distributive justice to John Rawls and examines two arguments in his work which might be taken to contain the seeds of the focus on responsibility in later theories of distributive justice. It examines Ronald Dworkin's ‘equality of resources’, the ‘luck egalitarianism’ of Richard Arneson and G. A. Cohen, as well as the criticisms of their work put forward (...) by Elizabeth Anderson, Marc Fleurbaey, Susan Hurley, and Jonathan Wolff. Key concepts such as responsibility (individual and collective), luck (thin and thick; brute and option), control, desert, and equality of opportunity are delineated, and the implementation of responsibility-sensitive accounts of justice is considered. The chapters of this book are positioned in relation to the wider literature on responsibility and distributive justice, and a brief outline of the chapters is provided. (shrink)

In this paper, we shall describe and critically evaluate four contemporary theories which attempt to solve the problem of the infinite regress of reasons: BonJour's ‘impure’ coherentism, BonJour's foundationalism, Haack's ‘foundherentism’ and Dancy's pure coherentism. These theories are initially put forward as theories about the justification of our empirical beliefs; however, in fact they also attempt to provide a successful response to the question of their own ‘metajustification.’ Yet, it will be argued that 1) none of the examined theories is (...) successful as a theory of justification of our empirical beliefs, and that 2) they also fall short of being adequate theories of metajustification. It will be further suggested that the failure of these views on justification is not coincidental, but is actually a consequence of deeper and tacitly held problematic epistemological assumptions (namely, the requirements of justificatory generality and epistemic priority), whose acceptance paves the way towards a generalized scepticism about empirical justification.

Given the fundamental role that concepts play in theories of cognition, philosophers and cognitive scientists have a common interest in concepts. Nonetheless, there is a great deal of controversy regarding what kinds of things concepts are, how they are structured, and how they are acquired. This chapter offers a detailed high-level overview and critical evaluation of the main theories of concepts and their motivations. Taking into account the various challenges that each theory faces, the chapter also presents a novel approach (...) to concepts that is organized around two ideas. The first is a pluralistic view of differing types of conceptual structure. The second is a model that treats concepts as atomic representations that are linked to various types of conceptual structures. (shrink)

Noam Chomsky's Poverty of the Stimulus Argument is one of the most famous and controversial arguments in the study of language and the mind. Though widely endorsed by linguists, the argument has met with much resistance in philosophy. Unfortunately, philosophical critics have often failed to fully appreciate the power of the argument. In this paper, we provide a systematic presentation of the Poverty of the Stimulus Argument, clarifying its structure, content, and evidential base. We defend the argument against a variety (...) of philosophical criticisms, new and old, and argue that the Poverty of the Stimulus Argument continues to deserve its guiding role in the study of language and the mind.

The aim of this paper is to extract from Kant's writings an account of the nature of the emotions and their function – and to do so despite the fact that Kant neither uses the term ‘emotion’ nor offers a systematic treatment of it. Kant's position, as I interpret it, challenges the contemporary trends that define emotions in terms of other mental states and defines them instead first and foremost as ‘feelings’. Although Kant's views on the nature of feelings have (...) drawn surprisingly little attention, I argue that the faculty of feeling has the distinct role of making us aware of the way our faculties relate to each other and to the world. As I show, feelings are affective appraisals of our activity, and as such they play an indispensable orientational function in the Kantian mind. After spelling out Kant's distinction between feeling and desire, I turn to the distinction between feeling and cognition and show that while feelings are non-cognitive states, they have a form of derived-intentionality. §4 argues that what feelings are about, in this derived sense, is our relationship to ourselves and the world: they function as affective appraisals of the state of our agency. §5 shows that this function is necessary to the activity of the mind insofar as it is orientational. Finally, §6 discusses the examples of epistemic pleasure and moral contentment and argues that they manifest the conditions of cognitive and moral agency respectively. (shrink)

Conceptual analysis is undergoing a revival in philosophy, and much of the credit goes to Frank Jackson. Jackson argues that conceptual analysis is needed as an integral component of so-called serious metaphysics and that it also does explanatory work in accounting for such phenomena as categorization, meaning change, communication, and linguistic understanding. He even goes so far as to argue that opponents of conceptual analysis are implicitly committed to it in practice. We show that he is wrong on all of (...) these points and that his case for conceptual analysis doesn't succeed. At the same time, we argue that the sorts of intuitions that figure in conceptual analysis may still have a significant role to play in philosophy. So naturalists needn't disregard intuitions altogether. (shrink)

Radical concept nativism is the thesis that virtually all lexical concepts are innate. Notoriously endorsed by Jerry Fodor (1975, 1981), radical concept nativism has had few supporters. However, it has proven difficult to say exactly what’s wrong with Fodor’s argument. We show that previous responses are inadequate on a number of grounds. Chief among these is that they typically do not achieve sufficient distance from Fodor’s dialectic, and, as a result, they do not illuminate the central question of how new (...) primitive concepts are acquired. To achieve a fully satisfactory response to Fodor’s argument, one has to juxtapose questions about conceptual content with questions about cognitive development. To this end, we formulate a general schema for thinking about how concepts are acquired and then present a detailed illustration. (shrink)

One of the most important recent developments in the study of concepts has been the resurgence of interest in nativist accounts of the human conceptual system. However, many theorists suppose that a key feature of neural organization—the brain’s plasticity—undermines the nativist approach to concept acquisition. We argue that, on the contrary, not only does the brain’s plasticity fail to undermine concept nativism, but a detailed examination of the neurological evidence actually provides powerful support for concept nativism.

Epistemic Courage is a timely and thought-provoking exploration of the ethics of belief, which shows why epistemology is no mere academic abstraction - the question of what to believe couldn't be more urgent. Jonathan Ichikawa argues that a skeptical, negative bias about belief is connected to a conservative bias that reinforces the status quo.

According to an intriguing though somewhat enigmatic line of thought first proposed by Jonathan Bennett, if humanity went extinct any time soon this would be unfortunate because important business would be left unfinished. This line of thought remains largely unexplored. I offer an interpretation of the idea that captures its intuitive appeal, is consistent with plausible constraints, and makes it non-redundant to other views in the literature. The resulting view contrasts with a welfare-promotion perspective, according to which extinction would (...) be bad because it would come at a massive opportunity cost in terms of feasibly achievable welfare over the lifetime of our species.

One of the most important abilities we have as humans is the ability to think about number. In this chapter, we examine the question of whether there is an essential connection between language and number. We provide a careful examination of two prominent theories according to which concepts of the positive integers are dependent on language. The first of these claims that language creates the positive integers on the basis of an innate capacity to represent real numbers. The second claims (...) that language’s function is to integrate contents from modules that humans share with other animals. We argue that neither model is successful. (shrink)

Jonathan Y. Tsou examines and defends positions on central issues in philosophy of psychiatry. The positions defended assume a naturalistic and realist perspective and are framed against skeptical perspectives on biological psychiatry. Issues addressed include the reality of mental disorders; mechanistic and disease explanations of abnormal behavior; definitions of mental disorder; natural and artificial kinds in psychiatry; biological essentialism and the projectability of psychiatric categories; looping effects and the stability of mental disorders; psychiatric classification; and the validity of the (...) DSM's diagnostic categories. The main argument defended by Tsou is that genuine mental disorders are biological kinds with harmful effects. This argument opposes the dogma that mental disorders are necessarily diseases that result from biological dysfunction. Tsou contends that the broader ideal of biological kinds offers a more promising and empirically ascertainable naturalistic standard for assessing the reality of mental disorders and the validity of psychiatric categories.

Philosophers have often claimed that general ideas or representations have their origin in abstraction, but it remains unclear exactly what abstraction as a psychological process consists in. We argue that the Lockean aspiration of using abstraction to explain the origins of all general representations cannot work and that at least some general representations have to be innate. We then offer an explicit framework for understanding abstraction, one that treats abstraction as a computational process that operates over an innate quality space (...) of fine-grained general representations. We argue that this framework has important philosophical implications for the nativism-empiricism dispute, for questions about the acquisition of unstructured representations, and for questions about the relation between human and animal minds.

The notion of domain specificity plays a central role in some of the most important debates in cognitive science. Yet, despite the widespread reliance on domain specificity in recent theorizing in cognitive science, this notion remains elusive. Critics have claimed that the notion of domain specificity can't bear the theoretical weight that has been put on it and that it should be abandoned. Even its most steadfast proponents have highlighted puzzles and tensions that arise once one tries to go beyond (...) an initial intuitive sketch of what domain specificity involves. In this paper, we address these concerns head on by developing an account of what it means for a cognitive mechanism to be domain specific that overcomes the obstacles that have made domain specificity seem so problematic. We then apply this understanding of domain specificity to one of the key debates that it has figured prominently in—the rationalism-empiricism debate concerning the origins of cognitive traits—and introduce several related theoretical notions that work alongside domain specificity in helping to clarify what makes a view more (or less) rationalist. This example illustrates how the notion of domain specificity can, and should, continue to play a central role in ongoing debates in cognitive science. (shrink)

This article gives an overview of some recent debates about the relationship between reasons and rational requirements of coherence - e.g. the requirements to be consistent in our beliefs and intentions, and to intend what we take to be the necessary means to our ends.

Generics are sentences such as Birds fly, which express generalizations. They are prevalent in speech, and as far as is known, no human language lacks generics. Yet, it is very far from clear what they mean. After all, not all birds fly—penguins don’t! -/- There are two general views about the meaning of generics in the literature, and each view encompasses many specific theories. According to the inductivist view, a generic states that a sufficient number of individuals satisfy a certain (...) property—in the example above, it says that sufficiently many birds fly. This view faces the complicated problem of spelling out exactly how many is “sufficiently many” in a way that correctly captures the intuitive truth conditions of generics. -/- An alternative, the rules and regulations view, despairs from this project and proposes instead that generics directly express rules in the world. Rules are taken to be abstract objects, which are not related to the properties of specific individuals. This view faces the difficult problem of explaining how people come to know of such rules when judging the truth of falsity of generics, and accounting for the strong intuition that a sentence such as Birds fly talks about birds, not abstract objects. -/- What seems to be beyond dispute is that generics, even if they do not express rules, are lawlike: they state non-accidental generalizations. Many scholars have taken this fact to indicate that generics are parametric on possible worlds: they refer to worlds other than the actual world. This, again, raises the problem of how people come to know about what happens in these other worlds. However, a rigorous application of standard tests for intensionality shows that generics are not, in fact, parametric on possible worlds, but only on time. This unusual property may explain much of the mystery surrounding generics. -/- Another mysterious property of generics is that although there is no language without them, there is no linguistic construction that is devoted to the expression of genericity. Rather, generics can be expressed in a variety of ways, each of which can also express nongenerics. Yet, each manifestation of generics differs subtly (or sometimes not so subtly) in its meaning from the others. -/- Even when these and other puzzles of genericity are solved, one mystery would remain: Why are generics, which are so easy to produce and understand in conversation, so difficult to analyze?

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)

We are all guided by thousands of norms, but how did our capacity for normative cognition evolve? I propose there is a deep but neglected link between normative cognition and practical skill. In modern humans, complex motor skills and craft skills, such as toolmaking, are guided by internally represented norms of correct performance. Moreover, it is plausible that core components of human normative cognition evolved as a solution to the distinctive problems of transmitting complex motor skills and craft skills, especially (...) skills related to toolmaking, through social learning. If this is correct, the expansion of the normative domain beyond technique to encompass more abstract norms of fairness, reciprocity, ritual and kinship involved the elaboration of a basic platform for the guidance of skilled action by technical norms. This article motivates and defends this “skill hypothesis” for the origin of normative cognition and sets out various ways in which it could be empirically tested. (shrink)

Consciousness has an important role in ethics: when a being consciously experiences the frustration or satisfaction of its interests, those interests deserve higher moral priority than those of a behaviourally similar but non-conscious being. I consider the relationship between this ethical role and an a posteriori (or “type-B”) materialist solution to the mind-body problem. It is hard to avoid the conclusion that, if type-B materialism is correct, then the reference of the concept of phenomenal consciousness is radically indeterminate between a (...) neuronal-level property that is distinctive to mammals and a high-level functional property that is much more widely shared. This would leave many non-mammalian animals (such as birds, fish, insects and octopuses) with indeterminate moral status. There are ways to manage this radical moral indeterminacy, but all of these ways lead to profoundly troubling consequences. (shrink)
