Any creature that must move around in its environment to find nutrients and mates, in order to survive and reproduce, faces the problem of sensorimotor control. A solution to this problem requires an on-board control mechanism that can shape the creature’s behaviour so as to render it “appropriate” to the conditions that obtain. There are at least three ways in which such a control mechanism can work, and Nature has exploited them all. The first and most basic way is for (...) a creature to bump into the things in its environment, and then, depending on what has been encountered, seek to modify its behaviour accordingly. Such an approach is risky, however, since some things in the environment are distinctly unfriendly. A second and better way, therefore, is for a creature to exploit ambient forms of energy that carry information about the distal structure of the environment. This is an improvement on the first method since it enables the creature to respond to the surroundings without actually bumping into anything. Nonetheless, this second method also has its limitations, one of which is that the information conveyed by such ambient energy is often impoverished, ambiguous and intermittent. (shrink)

When cognitive scientists apply computational theory to the problem of phenomenal consciousness, as many of them have been doing recently, there are two fundamentally distinct approaches available. Either consciousness is to be explained in terms of the nature of the representational vehicles the brain deploys; or it is to be explained in terms of the computational processes defined over these vehicles. We call versions of these two approaches _vehicle_ and _process_ theories of consciousness, respectively. However, while there may be space (...) for vehicle theories of consciousness in cognitive science, they are relatively rare. This is because of the influence exerted, on the one hand, by a large body of research which purports to show that the explicit representation of information in the brain and conscious experience are _dissociable_, and on the other, by the _classical_ computational theory of mind – the theory that takes human cognition to be a species of symbol manipulation. But two recent developments in cognitive science combine to suggest that a reappraisal of this situation is in order. First, a number of theorists have recently been highly critical of the experimental methodologies employed in the dissociation studies – so critical, in fact, it’s no longer reasonable to assume that the dissociability of conscious experience and explicit representation has been adequately demonstrated. Second, classicism, as a theory of human cognition, is no longer as dominant in cognitive science as it once was. It now has a lively competitor in the form of _connectionism; _and connectionism, unlike classicism, does have the computational resources to support a robust vehicle theory of consciousness. In this paper we develop and defend this connectionist vehicle theory of consciousness. It takes the form of the following simple empirical hypothesis: _phenomenal experience consists in the explicit_ _representation of information in neurally realized PDP networks_.. (shrink)

One of the principal tasks Dennett sets himself in Consciousness Explained is to demolish the Cartesian theater model of phenomenal consciousness, which in its contemporary garb takes the form of Cartesian materialism: the idea that conscious experience is a process of presentation realized in the physical materials of the brain. The now standard response to Dennett is that, in focusing on Cartesian materialism, he attacks an impossibly naive account of consciousness held by no one currently working in cognitive science or (...) the philosophy of mind. Our response is quite different. We believe that, once properly formulated, Cartesian materialism is no straw man. Rather, it is an attractive hypothesis about the relationship between the computational architecture of the brain and phenomenal consciousness, and hence one that is worthy of further exploration. Consequently, our primary aim in this paper is to defend Cartesian materialism from Dennett’s assault. We do this by showing that Dennett’s argument against this position is founded on an implicit assumption (about the relationship between phenomenal experience and information coding in the brain), which while valid in the context of classical cognitive science, is not forced on connectionism.

Green offers us two options: either connectionist models are literal models of brain activity or they are mere instruments, with little or no ontological significance. According to Green, only the first option renders connectionist models genuinely explanatory. I think there is a third possibility. Connectionist models are not literal models of brain activity, but neither are they mere instruments. They are abstract, IDEALISED models of the brain that are capable of providing genuine explanations of cognitive phenomena.

Although connectionism is advocated by its proponents as an alternative to the classical computational theory of mind, doubts persist about its _computational_ credentials. Our aim is to dispel these doubts by explaining how connectionist networks compute. We first develop a generic account of computation—no easy task, because computation, like almost every other foundational concept in cognitive science, has resisted canonical definition. We opt for a characterisation that does justice to the explanatory role of computation in cognitive science. Next we examine (...) what might be regarded as the “conventional” account of connectionist computation. We show why this account is inadequate and hence fosters the suspicion that connectionist networks aren’t genuinely computational. Lastly, we turn to the principal task of the paper: the development of a more robust portrait of connectionist computation. The basis of this portrait is an explanation of the representational capacities of connection weights, supported by an analysis of the weight configurations of a series of simulated neural networks.

It is commonplace for both philosophers and cognitive scientists to express their allegiance to the "unity of consciousness". This is the claim that a subject’s phenomenal consciousness, at any one moment in time, is a single thing. This view has had a major influence on computational theories of consciousness. In particular, what we call single-track theories dominate the literature, theories which contend that our conscious experience is the result of a single consciousness-making process or mechanism in the brain. We argue (...) that the orthodox view is quite wrong: phenomenal experience is not a unity, in the sense of being a single thing at each instant. It is a multiplicity, an aggregate of phenomenal elements, each of which is the product of a distinct consciousness-making mechanism in the brain. Consequently, cognitive science is in need of a multi-track theory of consciousness; a computational model that acknowledges both the manifold nature of experience, and its distributed neural basis. (shrink)

We think the best prospect for a naturalistic explanation of phenomenal consciousness is to be found at the confluence of two influential ideas about the mind. The first is the _computational _ _theory of mind_: the theory that treats human cognitive processes as disciplined operations over neurally realised representing vehicles.1 The second is the _representationalist theory of _ _consciousness_: the theory that takes the phenomenal character of conscious experiences (the “what-it-is-likeness”) to be constituted by their representational content.2 Together these two (...) theories suggest that phenomenal consciousness might be explicable in terms of the representational content of the neurally realised representing vehicles that are generated and manipulated in the course of cognition. The simplest and most elegant hypothesis that one might entertain in this regard is that conscious experiences are identical to (i.e., are one and the same as) the brain’s representing vehicles.

In this paper we defend a position we call radical connectionism. Radical connectionism claims that cognition _never_ implicates an internal symbolic medium, not even when natural language plays a part in our thought processes. On the face of it, such a position renders the human capacity for abstract thought quite mysterious. However, we argue that connectionism is committed to an analog conception of neural computation, and that representation of the abstract is no more problematic for a system of analog vehicles (...) than for a symbol system. Natural language is therefore not required as a representational medium for abstract thought. Since natural language is arguably not a representational medium _at all_, but a conventionally governed scheme of communicative signals, we suggest that the role of internalised (i.e., self- directed) language is best conceived in terms of the coordination and control of cognitive activities within the brain.

Consciousness is a pretty sexy topic right now, as the plethora of recent books on the subject demonstrate. Everyone is having a go at it: philosophers, psychologists, neuroscientists and physicists, to mention just a few. And for every discipline or sub-discipline that pretends to some insight on the matter we find not only a different explanatory strategy, but a different take on the explanandum – there is widespread disagreement about what a theory of consciousness should actually explain. However, one thing (...) seems to be agreed by all concerned: consciousness, whatever it is, is deeply mysterious. (shrink)

The connectionist vehicle theory of phenomenal experience in the target article identifies consciousness with the brain’s explicit representation of information in the form of stable patterns of neural activity. Commentators raise concerns about both the conceptual and empirical adequacy of this proposal. On the former front they worry about our reliance on vehicles, on representation, on stable patterns of activity, and on our identity claim. On the latter front their concerns range from the general plausibility of a vehicle theory to (...) our specific attempts to deal with the dissociation studies. We address these concerns, and then finish by considering whether the vehicle theory we have defended has a coherent story to tell about the active, unified subject to whom conscious experiences belong.

In restricting his analysis to the causal relations of functionalism, on the one hand, and the neurophysiological realizers of biology, on the other, Palmer has overlooked an alternative conception of the relationship between color experience and the brain - one that liberalises the relation between mental phenomena and their physical implementation, without generating functionalism.

One of the most striking manifestations of schizophrenia is thought insertion. People suffering from this delusion believe they are not the author of thoughts which they nevertheless own as experiences. It seems that a person’s sense of agency and their sense of the boundary between mind and world can come apart. Schizophrenia thus vividly demonstrates that self awareness is a complex construction of the brain. This point is widely appreciated. What is not so widely appreciated is how radically schizophrenia challenges (...) our assumptions about the nature of the self. Most theorists endorse the traditional doctrine of the unity of consciousness, according to which a normal human brain generates a single consciousness at any instant in time. In this paper we argue that phenomenal consciousness at each instant is actually a multiplicity: an aggregate of phenomenal elements, each of which is the product of a distinct consciousness-making mechanism in the brain. We then consider how certain aspects of self might emerge from this manifold substrate, and speculate about the origin of thought insertion. (shrink)

Martínez-Manrique contends that we overlook a possible nonconnectionist vehicle theory of consciousness. We argue that the position he develops is better understood as a hybrid vehicle/process theory. We assess this theory and in doing so clarify the commitments of both vehicle and process theories of consciousness.

Dienes & Perner offer us a theory of explicit and implicit knowledge that promises to systematise a large and diverse body of research in cognitive psychology. Their advertised strategy is to unpack this distinction in terms of explicit and implicit representation. But when one digs deeper one finds the “Higher-Order Thought” theory of consciousness doing much of the work. This reduces both the plausibility and usefulness of their account. We think their strategy is broadly correct, but that consensus on the (...) explicit/implicit knowledge distinction is still a fair way off. (shrink)

How should one understand knowledge-wh ascriptions? That is, how should one understand claims such as ‘‘I know where the car is parked,’’ which feature an interrogative complement? The received view is that knowledge-wh reduces to knowledge that p, where p happens to be the answer to the question Q denoted by the wh-clause. I will argue that knowledge-wh includes the question—to know-wh is to know that p, as the answer to Q. I will then argue that knowledge-that includes a contextually (...) implicit question. I will conclude that knowledge is a question-relative state. Knowing is knowing the answer, and whether one knows the answer depends (in part) on the question. (shrink)

Understanding consciousness and its place in the natural world is one of the principal targets of contemporary philosophy of mind. Australian philosophers made seminal contributions to this project during the twentieth century which continue to shape the way philosophers and scientists think about the conceptual, metaphysical and empirical aspects of the problem. After some scene setting, I will discuss the main players and their work in the context of broader developments in the philosophy of mind.

This title presents a comprehensive guide to interpretative phenomenological analysis (IPA) which is an increasingly popular approach to qualitative inquiry taught to undergraduate and postgraduate students today.

This article explores the promises of critical hermeneutics as an innovative method and philosophy within the human sciences. It is argued that its success depends on its ability to articulate a theory of meaning with one of action and experience as well as its capacity to renew our understanding of the problem of ideology. First, critical hermeneutics must explain how cultural messages ‘show and hide’; that is, how the ambiguity of meaning always allows for a group to represent itself while (...) opening the door for distortion and domination. Second, critical hermeneutics ought to show how action can be best understood as opposing performances driven by ideological-moral views. Through an analysis of social movements, for instance, it is shown that any attempt to do justice could also and easily create exclusion. Third, critical hermeneutics has to clarify how tension and dualism within meaning and action are not to be dissociated from the self-interpretation of concrete individuals. A theory of experience is thus required in order to explain why the autonomy of the subject is finally at stake with regard to the problem of ideology. (shrink)

Causal claims are context sensitive. According to the old orthodoxy (Mackie 1974, Lewis 1986, inter alia), the context sensitivity of causal claims is all due to conversational pragmatics. According to the new contextualists (Hitchcock 1996, Woodward 2003, Maslen 2004, Menzies 2004, Schaffer 2005, and Hall ms), at least some of the context sensitivity of causal claims is semantic in nature. I want to discuss the prospects for causal contextualism, by asking why causal claims are context sensitive, what they are sensitive (...) to, and where they are sensitive to it. (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.

Various scientists and philosophers have heavily criticized what they see as problematic forms of ‘nutritional reductionism’ or ‘nutritionism’ whereby studying food–health interactions at the level of isolated food components produces largely misguided science and misleading interpretations. However, the exact target of these diverse criticisms remains elusive, and its implications are overstated, which may hinder scientific understanding. To better identify the types of flaws supposedly hindering reductionist research, we disentangle three types of reductionist claims to better determine what the debate is (...) about and to propose ways to move it forward. We then present a qualified defence of the reductionist programme that hinges on the ability to identify nutritional causes that make a difference, which we illustrate through central examples in the history of nutrition. This defence is taken further by using insights from the philosophy of mechanisms to analyse how the field of nutritional ecology offers a synthetic framework to explain, generate, and test predictions about nutrient–organism interactions, which is premised on the biological mechanisms of nutrient-specific appetite regulation. The result, which we call ‘synthetic reductionism’, avoids many, though perhaps not all, of the challenges raised by anti-reductionists, and also highlights the potential of reductionism to identify nutritional difference makers.

The idea of public reason is at the center of John Rawls's political philosophy. Public reason is a standard by which we measure laws and political institutions. This chapter discusses the practice of public reason, the moral basis of public reason, and the challenge posed by religious critics of public reason. It provides three possible answers to the question: What is the moral basis for endorsing this particular conception of democratic politics – public reason? It is Rawlsian concept of justice (...) – the ideal of a fair system of social cooperation between free and equal citizens – which provides the moral basis for public reason. Given this basis, citizens then engage in the practice of public reason with one another. (shrink)

The larger philosophical world has on the whole turned from a mix of averted gaze and outright antipathy toward x‐phi, to a mix of grudging acceptance and enthusiastic embrace. This chapter explains that the experimental philosophy is relevant, and that it is dangerous, and explains some ways that people can do more to remain both. Experimental philosophy's semi‐official sigil of the burning armchair has advertised its dangerousness for the past decade and a half as well. The chapter explains that it (...) is a threat that is every bit as potently present in positive program x‐phi as it is in negative program work. To explore the idea that experimental philosophy's positive contributions will still be primarily negative in nature, the chapter interrogates the passage from Timothy Williamson. It focuses on the wheat‐from‐chaff project of separating signal from noise in the evidence produced by intuitions and the like. (shrink)

Two debates in contemporary philosophical moral psychology have so far been conducted almost entirely in isolation from one another despite their structural similarity. One is the debate over the importance for virtue ethics of the results of situational manipulation experiments in social psychology. The other is the debate over the ethical implications of experiments that reveal gender and race biases in social cognition. In both cases, the ethical problem posed cannot be identified without first clarifying the cognitive structures underlying the (...) problematic phenomena. In this chapter, I argue that the two kinds of phenomena share a basic cognitive structure, which is well articulated by the findings of the empirical psychology of attitudes, especially if these findings are understood in the context of the cognitive-affective system theory of personality. On the basis of this joint construal of situationism and implicit bias, I argue that the negative programme of ethical improvement that many philosophers recommend in response to one or other problem is unrealistic. Instead, we should consider more seriously the prospects of the positive programme of ethical improvement recommended by Aristotle, the direct aim of which is to instil deeply in ourselves the values at the heart of each of the virtues.

Ross Cameron proposes to reconcile presentism and truth-maker theory by invoking temporal distributional properties, instantiated by present entities, as the truth-makers for truths about the past. This chapter argues that Cameron's proposal fails because objects can change which temporal distributional properties they instantiate and this entails that the truth-values of truths about the past can change in an objectionable way.

We aim to introduce presentism and to consider the question that presentism is supposed to answer. That is, if “only present objects exist” (or some appropriate precisification of the slogan) is the answer to a philosophical question, then (i) what is the question? And (ii) is it the right question to ask? We suggest that the question presentists are answering is not a good one to ask. We aim to articulate a question that presentists, or the heirs of presentism, should (...) try to answer. In pursuing these aims, we provide the reader with a sense of how we have reached the current position in the literature, as well as how we might move it along. (shrink)

Written by leading theorists and empirical researchers, this book presents new ways of addressing the old question: Why did religion first emerge and then continue to evolve in all human societies? The authors of the book--each with a different background across the social sciences and humanities -- assimilate conceptual leads and empirical findings from anthropology, evolutionary biology, evolutionary sociology, neurology, primate behavioral studies, explanations of human interaction and group dynamics, and a wide range of religious scholarship to construct a deeper (...) and more powerful explanation of the origins and subsequent evolutionary development of religions than can be currently found in what is now vast literature. While explaining religion has been a central question in many disciplines for a long time, this book draws upon a much wider array of literatures to develop a robust and cross-disciplinary analysis of religion. The book remains true to its subtitle by emphasizing an array of both biological and sociocultural forms of selection dynamics that are fundamental to explaining religion as a universal institution in human societies. In addition to Darwinian selection, which can explain the biology and neurology of religion, the book outlines a set of four additional types of sociocultural natural selection that can explain fill out the explanation of why religion first emerged as an institutional system in human societies, and why it has continued to evolve over the last 200,000 years of societal evolution. These sociocultural forms of natural selection are labeled by the names of the early sociologists who first emphasized them; and these can be seen as a necessary supplement to the type of natural selection theorized by Charles Darwin. Explanations of religion that remain in the shadow cast by Darwin's great insights will, it is argued, remain narrow and incomplete when explaining a robust sociocultural phenomena like religion.

Sociology is experiencing what can only be described as hyperdifferentiation of theories - there are now many approaches competing for attention in the intellectual arena. From this perspective, we should see a weeding out of theories to a small number, but this is not likely to occur because each of the many theoretical perspectives has a resource base of adherents. As a result, theories in sociology do not compete head on with each other as much as they coexist. This seminal (...) reference work was brought together with an eye to capturing the diversity of theoretical activity in sociology - specifically the forefront of theory. Contributors describe what they themselves are doing right now rather than what others have done in the past. The goal of this volume is to allow prominent theorists working in a variety of traditions - who wouldn't usually come together - to review their work. The chapters in this volume represent a mix of theoretical orientations and strategies, but these these theories are diverse and represent the prominent theoretical discussions in sociology today. Some areas included are: Section I: Theoretical Methodologies and Strategies Section II: The Cultural Turn in Sociological Theorizing Section III: Theorizing Interaction Processes Section IV: Theorizing from the Systemic and Macrolevel Section V: New Directions in Evolutionary Theorizing Section VI: Theorizing on Power, Conflict, and Change SectionVII: Theorizing from Assumptions of Rationality This handbook will be of interest to those wanting a broad spectrum and overview of late 20th - early 21st century sociological theory.

Skeptical theists have paid insufficient attention to non-evidential components of epistemic rationality. I address this lacuna by constructing an alternative perspectivalist understanding of epistemic rationality and defeat that, when applied to skeptical theism, yields a more demanding standard for reasonably affirming the crucial premise of the evidential argument from suffering. The resulting perspectival skeptical theism entails that someone can be justified in believing that gratuitous suffering exists only if they are not subject to closure-of-inquiry defeat; that is, a type of (...) defeat that prevents reasonable belief that p even if p is very probable on an agent’s evidence.

The theme of this collection of articles by Jonathan Turner is that sociology can be a true science, and it can develop abstract laws explaining the operative dynamics of the social universe. Rather that blindly worshipping sociology's masters, however, Turner attempts to reinvent sociology as a science that learns the valuable lessons of classical theory and then moves on.

Xenophobia is one of the key drivers of marginalisation, discrimination, and conflict, yet many prominent machine learning fairness frameworks fail to comprehensively measure or mitigate the resulting xenophobic harms. Here we aim to bridge this conceptual gap and help facilitate safe and ethical design of artificial intelligence (AI) solutions. We ground our analysis of the impact of xenophobia by first identifying distinct types of xenophobic harms, and then applying this framework across a number of prominent AI application domains, reviewing the (...) potential interplay between AI and xenophobia on social media and recommendation systems, healthcare, immigration, employment, as well as biases in large pre-trained models. These help inform our recommendations towards an inclusive, xenophilic design of future AI systems. (shrink)

The collaboration of Language and Computing nv (L&C) and the Institute for Formal Ontology and Medical Information Science (IFOMIS) is guided by the hypothesis that quality constraints on ontologies for software ap-plication purposes closely parallel the constraints salient to the design of sound philosophical theories. The extent of this parallel has been poorly appreciated in the informatics community, and it turns out that importing the benefits of phi-losophical insight and methodology into application domains yields a variety of improvements. L&C’s LinKBase® (...) is one of the world’s largest medical domain ontologies. Its current primary use pertains to natural language processing ap-plications, but it also supports intelligent navigation through a range of struc-tured medical and bioinformatics information resources, such as SNOMED-CT, Swiss-Prot, and the Gene Ontology (GO). In this report we discuss how and why philosophical methods improve both the internal coherence of LinKBase®, and its capacity to serve as a translation hub, improving the interoperability of the ontologies through which it navigates.

In his Natural Theology, the eighteenth-century Anglican theologian William Paley compares a watch with objects in nature, arguing that “every manifestation of design, which existed in the watch, exists in the works of nature…” Charles Darwin read Paley's Natural Theology as a young man and offered natural selection as an alternative, naturalistic explanation of Paley's explanandum: the appearance of design in nature. Many of Paley's successors diverged from him in their approach to the living world. This chapter examines some of (...) these alternative approaches and the extent to which the literature of natural theology had trodden the path between Paley's watchmaker and Darwin's natural selection prior to the publication of the latter's Origin of Species. In particular, it focuses on the Bridgewater Treatises, a series of eight highly popular works published in the 1830s, which illustrate the far-reaching development that took place in natural theology in Britain during the early nineteenth century.

Jean-Paul Sartre developed a sophisticated and insightful feminist critique of western society through two plays and two screenplays written between 1944 and 1946 –– Huis clos, Les Jeux sont faits, Typhus, and La Putain respectueuse. In these works, Sartre explores the relations between economic oppression, epistemic injustice, and misogynistic violence, diagnoses their root cause as the patriarchal norms of femininity and masculinity, and ascribes the power of those norms to bad faith and internalized oppression. This social critique, which includes a (...) racial dimension, informs some of his subsequent fictional and philosophical writings. Sartre’s analysis of patriarchy has not been noted in writings about these famous dramatic works, a distortion which seems partly due to those same patriarchal norms. (shrink)

Mill advocates plural voting on instrumentalist grounds: the more competent are to have more votes. At the same time, he regards it as a ‘personal injustice’ to withhold from anyone ‘the ordinary privilege of having his voice reckoned in the disposal of affairs in which he has the same interest as other people’ (Mill 1861a, p. 469). But if electoral voice is justified by its contribution to good governance, why would it be an injustice to deny the vote to those (...) whose use of it would disserve this end? I propose the dual justification view to resolve this tension. Mill holds that electoral voice is to be justified in two complementary ways: both as communicating a person’s interests and perspective in order that they be accommodated in policy deliberations, and as advancing a vision of the common good and influencing the policy of the legislature.
