First published in 1984 as part of The Collected Papers of Bertrand Russell , Theory of Knowledge represents an important addition to our knowledge of Russell's thought. In this work Russell attempts to flesh out the sketch implicit in The Problems of Philosophy . It was conceived by Russell as his next major project after Principia Mathematica and was intended to provide the epistemological foundations for his work. Russell's subsequent difficulties in presenting his theory of knowledge, brought on by what (...) he considered to be devastating criticisms of Wittgenstein, led to both his abandonment of this work and to a major transformation in his thought. Theory of Knowledge , now available for the first time in paperback, gives us a picture of one of the great minds of the twentieth century at work. It is possible to see the unsolved problems left without disguise or evasion. This second edition has retained the full scholarly introduction. The photographs of the manuscript, appendices, and notes on textual matters have been eliminated to provide a concise and accessible guide to understanding both Russell's own thought and his relationship with Wittgenstein.

On Kant's view, the feeling of respect is the mark of moral agency, and is peculiar to us, animals endowed with reason. Unlike any other feeling, respect originates in the contemplation of the moral law, that is, the idea of lawful activity. This idea works as a constraint on our deliberation by discounting the pretenses of our natural desires and demoting our selfish maxims. We experience its workings in the guise of respect. Respect shows that from the agent's subjective perspective, (...) morality is the experience of being bound and necessitated, but also of being free and emancipated from inclinations.Respect is a feeling that is generated by the agent's reflection on the nature of her own agency. It is not directed to anybody in particular, but to the very idea of rational agency, which is characterized by self-mastery and self-legislation. Contrary to animals, we do not derive our ends from nature, but we are capable of setting ends of our own, by exercising practical reason, that is, by engaging in the activity of law making.

Jennings and Nanay argue against my claim that action entails attention by providing putative counterexamples to the claim that action entails a Many–Many Problem. This reply demonstrates that they have misunderstood the central notion of a pure reflex on which my argument depends. A simplified form of the argument from pure reflex to the Many–Many Problem as a necessary feature of agency is given, and putative counterexamples of action without attention are addressed. Attention is present in every action. In passing, (...) the reply discusses how we should assess intuitive claims about attention and mental processing, with emphasis on learning and the automatization of attention in its development as a skill.

In this paper, I examine the role of attention in Kant’s aesthetic theory in the Critique of the Power of Judgment. While broadly Kantian aestheticians have defended the claim that there is a distinct way that we attend to objects in aesthetic experience, Kant himself is not usually acknowledged as offering an account of aesthetic attention. On the basis of Kant’s more general account of attention in other texts and his remarks on attention in the Critique of the Power of (...) Judgment, I reconstruct Kant’s account of aesthetic attention. On this account, aesthetic attention is simultaneously directed at the form of an object and at the judging subject’s own mental states as she attends to the object. In the experience of beauty, we specifically attend to the harmonious relation between the faculties of imagination and understanding. (shrink)

I argue that when perception plays a guiding role in intentional bodily action, it is a necessary part of that action. The argument begins with a challenge that necessarily arises for embodied agents, what I call the Many-Many Problem. The Problem is named after its most common case where agents face too many perceptual inputs and too many possible behavioral outputs. Action requires a solution to the Many-Many Problem by selection of a specific linkage between input and output. In bodily (...) action the agent perceptually selects, and in this way perceptually attends to, relevant information so as to guide the execution of specific movements. Since perceptual attention is a necessary part of solving the Many-Many Problem, it is a necessary part of bodily action. Indeed, the process of implementing a solution to the Many-Many Problem, as constrained by the agent's motivational state, just is the agent's performing an intentional bodily action in the relevant way.

Because the visual system cannot process all of the objects, colors, and features present in a visual scene, visual attention allows some visual stimuli to be selected and processed over others. Most research on visual attention has focused on spatial or location-based attention, in which the locations occupied by stimuli are selected for further processing. Recent research, however, has demonstrated the importance of objects in organizing (or segregating) visual scenes and guiding attentional selection. Because of the long history of spatial (...) attention research, theories of spatial attention are more mature than theories of other visual processes, such as object segregation and object attention. In the present paper, I outline a biased competition account of object segregation and attention, following similar accounts that have been developed for spatial attention (Desimone and Duncan, 1995). In my biased competition account, I seek to understand how some objects can be segregated and selected over other objects in a complex visual scene. Under this account, there are two sources of visual information that allow an object to be processed over other objects: bottom-up information carried by the physical stimulus and top-down information based on an observer's goals. I use the biased competition account to combine many diverse findings from the object segregation and attention literatures into a common framework. (shrink)

On a widely held view in aesthetics, appreciation requires disinterested attention. George Dickie famously criticized a version of this view championed by the aesthetic attitude theorists. I revisit his criticisms and extract an overlooked challenge for accounts that seek to characterize appreciative engagement in terms of distinctive motivation: at minimum, the motivational profile such accounts propose must make a difference to how appreciative episodes unfold over time. I then develop a proposal to meet this challenge by drawing an analogy between (...) how attention is guided in appreciation and how practical action is guided in ‘striving play’—a mode of game play recently foregrounded in the philosophy of games. On the resulting account, appreciation involves an ‘inverted’ motivational structure: the appreciating agent's attention is guided by cognitive goals taken up instrumentally, for the sake of the cognitive activity that results from attending under the guidance of those goals.

In many theories in contemporary philosophy of mind, attention is constitutively linked to phenomenal consciousness. Ned Block has recently argued that ‘identity crowding’ provides an example of subjects consciously seeing something to which they are unable to attend. Here I examine the reasons that Block gives for thinking that this is a case of a consciously perceived item that we are unable to attend to, and I offer a different interpretation.

There have recently been a number of attempts to put forth a philosophical account of the nature of attention. Many such theories aim at giving necessary and sufficient conditions for something to be attention. In this paper I will argue that any such theory must meet two criteria. Then I shall examine four prominent accounts of attention in some detail, and argue that all of them face problems meeting one or the other of the criteria. I propose an alternative view, (...) which involves taking seriously a pluralistic approach to attention. If the position I advocate is correct, then much of the philosophical work currently carried out on attention is fundamentally misguided, as most of the prominent theories of attention currently available are based upon assumptions which should be rejected.

In the mid twentieth century the philosopher Ludwig Wittgenstein famously asserted that games are indefinable; there are no common threads that link them all. "Nonsense," says the sensible Bernard Suits: "playing a game is a voluntary attempt to overcome unnecessary obstacles." The short book Suits wrote demonstrating precisely that is as playful as it is insightful, as stimulating as it is delightful. Suits not only argues that games can be meaningfully defined; he also suggests that playing games is a central (...) part of the ideal of human existence, so games belong at the heart of any vision of Utopia. Originally published in 1978, The Grasshopper is now re-issued with a new introduction by Thomas Hurka and with additional material (much of it previously unpublished) by the author, in which he expands on the ideas put forward in The Grasshopper and answers some questions that have been raised by critics.

Many alleged counter-examples to intentionalism, the thesis that the phenomenology of perceptual experiences of a given sense modality supervenes on the contents of experiences of that modality, can be avoided by adopting a liberal view of the sorts of properties that can be represented in perceptual experience. I argue that there is a class of counter-examples to intentionalism, based on shifts in attention, which avoids this response. A necessary connection between the contents and phenomenal characters of perceptual experiences can be (...) preserved by distinguishing perceptual phenomenology from the phenomenology of attention; but even if this distinction is viable, these cases put pressure on the thesis that phenomenal character can, in general, be explained in terms of mental representation.

It is a distinctive mark of normal conscious perception that perceived objects are experienced as actually present in one’s surroundings. The aim of this paper is to offer a phenomenologically accurate and empirically plausible account of the cognitive underpinning of this feature of conscious perception, which I shall call perceptual presence. The paper begins with a preliminary characterization of. I then consider and criticize the seminal account of proposed by Mohan Matthen. In the remainder of the paper I put forward (...) and defend my own attentional account. I first outline a simple version of the view by focusing on vision and then extend it to audition. After discussing the case of depersonalization, I consider some objections. The last objection, in particular, will motivate a refinement of the attentional account for the visual case. The paper ends with some remarks mainly about the specificity of the visual case vis-à-vis the auditory one. (shrink)

Contrary to Block's assertion, “identity-crowding” does not provide an interesting instance of object-seeing without object-attention. The successful judgments and unusual phenomenology of identity-crowding are better explained by unconscious perception and non-perceptual phenomenology associated with cognitive states. In identity-crowding, as in other cases of crowding, subjects see jumbled textures and cannot individuate the items contributing to those textures in the absence of attention. Block presents an attenuated sense in which identity-crowded items are seen, but this is irrelevant to the debate about (...) phenomenal experience of an object in the absence of object-attention. Finally, even unconscious object perception in identity-crowding likely involves an attention-like selective process. (shrink)

Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused attention is (...) needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)

It has recently become popular to suggest that cognition can be explained as a process of Bayesian prediction error minimization. Some advocates of this view propose that attention should be understood as the optimization of expected precisions in the prediction-error signal (Clark, 2013, 2016; Feldman & Friston, 2010; Hohwy, 2012, 2013). This proposal successfully accounts for several attention-related phenomena. We claim that it cannot account for all of them, since there are certain forms of voluntary attention that it cannot accommodate. (...) We therefore suggest that, although the theory of Bayesian prediction error minimization introduces some powerful tools for the explanation of mental phenomena, its advocates have been wrong to claim that Bayesian prediction error minimization is ‘all the brain ever does’.

Despite its prominent role in cognitive psychology, its relevance for the research of consciousness, and some helpful clarification (e.g., Revonsuo 1999), the binding problem is still surrounded by considerable confusion. In this paper, I first give an informal but systematic overview on the diversity of forms the binding problem can assume, and then attempt to extract, on the basis of "working definitions" of various much-discussed types of binding, a common denominator. I propose that at the heart of the binding problem (...) lies the notion of representing an entity as having a certain property, and discuss several objections that could be raised against the proposed analysis, as well its usefulness and implications.

I argue that perceptual content is always affected by the allocation of one’s attention. Perception attributes determinable and determinate properties to the perceived scene. Attention makes (or tries to make) our perceptual attribution of properties more determinate. Hence, a change in our attention changes the determinacy of the properties attributed to the perceived scene.

I argued in Nanay 2010 that we cannot characterize perceptual content without reference to attention. Here, I defend this account from three objections raised by Jagnow 2011. This mainly takes the form of clarifying some details not sufficiently elaborated in the original article and dispelling some potential misunderstandings.

A response to Christof Koch and Naotsugu Tsuchiya's 'Attention and Consciousness: Two Distinct Brain Processes'.

Representationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to account for Gestalt switching. (...) I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position. (shrink)

The nature of attention has been the topic of a lively research programme in psychology for over a century. But there is widespread agreement that none of the theories on offer manage to fully capture the nature of attention. Recently, philosophers have become interested in the debate again after a prolonged period of neglect. This paper contributes to the project of explaining the nature of attention. It starts off by critically examining Christopher Mole’s prominent “adverbial” account of attention, which traces (...) the failure of extant psychological theories to their assumption that attending is a kind of process. It then defends an alternative, process-based view of the metaphysics of attention, on which attention is understood as an activity and not, as psychologists seem to implicitly assume, an accomplishment. The entrenched distinction between accomplishments and activities is shown to shed new light on the metaphysics of attention. It also provides a novel diagnosis of the empirical state of play.

Attention has a role in much of perception, thought, and action. On the erotetic theory, the functional role of attention is a matter of the relationship between questions and what counts as answers to those questions. Questions encode the completion conditions of tasks for cognitive control purposes, and degrees of attention are degrees of sensitivity to the occurrence of answers. Questions and answers are representational contents given precise characterizations using tools from formal semantics, though attention does not depend on language. (...) The erotetic theory proposes an integrated account of attention in cognitive control and of attentional focus in perception. The functional role of attentional focus on objects, properties, and locations has to do with picking out something that corresponds to what a task is ‘about’. The erotetic theory of attention opens new avenues in theorizing about the relationship between attention, representational content, phenomenal character, and practical reason. A novel representationalist account of salience is proposed. The theory also provides an account of distraction that suggests when distraction is a defect in practical reasoning. (shrink)

The selection of wanted from unwanted messages requires discriminatory mechanisms of as great a complexity as those in normal perception, as is indicated by behavioral evidence. The results of neurophysiology experiments on selective attention are compatible with this supposition. This presents a difficulty for Filter theory. Another mechanism is proposed, which assumes the existence of a shifting reference standard, which takes up the level of the most important arriving signal. The way such importance is determined in the system is further (...) described. Neurophysiological evidence relative to this postulation is discussed. (shrink)

This paper explores whether consciousness can exist without attention. This is a hot topic in philosophy of mind and cognitive science due to the popularity of theories that hold attention to be necessary for consciousness. The discovery of a form of consciousness that exists without the influence of attention would require a change in the way that many global workspace theorists, for example, understand the role and function of consciousness. Against this understanding, at least three forms of consciousness have been (...) argued to exist without attention: perceptual gist, imagistic consciousness, and phenomenal consciousness. After first arguing that the evidence is inconclusive on the question of whether these forms of consciousness exist without attention, I here present a fourth form of consciousness that is likely to be more successful: conscious entrainment. I argue that conscious entrainment is a form of consciousness associated with skilled behavior in which attention is sometimes absent. (shrink)

The aim of this paper is to develop and defend an Attentional View of bodily awareness, on which attention is necessary for bodily awareness. The original formulation of the Attentional View is due to Marcel Kinsbourne. First, I will show that the Attentional View of bodily awareness as formulated by Kinsbourne is superior to other accounts in the literature for characterizing the relationship between attention and bodily awareness. Kinsbourne’s account is the only account in the literature so far which can (...) accommodate key neurological diseases such as personal neglect. Second, when I consider Kinsbourne’s view in more detail, I will argue that Kinsbourne’s Attentional View faces problems because it is too reductive. Kinsbourne deviates from the standard taxonomy on which there is a body schema and a body image. Instead he reduces the body image to the neural representation of the body in the somatosensory cortex, the body schema and attentional shifts. I will present two challenges to Kinsbourne’s view which demonstrate that Kinsbourne’s reduction of the body image is unsuccessful. Finally, I will present a revised version of the Attentional View that is both empirically adequate and philosophically satisfactory. (shrink)

The view that a mental state is “transparent” is the view that the mental state is such that we cannot direct our attention directly towards the mental state, and that instead, when we try to do so, we attend to something in the external world rather than the mental state itself. Results from the study of internal attention put transparency views under a pressure that has so far been entirely unacknowledged in the literature. I focus on Garavan (1998) study of (...) switching the focus of internal attention from one mental count to another mental count. I argue that Garavan’s results are evidence that we can direct our attention to occurrent thought, contra Alexander Byrne’s (2008, 2018) claim that occurrent thought is actually transparent.

In this paper, we investigate the role of intention and joint attention in joint actions. Depending on the shared intentions the agents have, we distinguish between joint path-goal actions and joint final-goal actions. We propose an instrumental account of basic joint action analogous to a concept of basic action and argue that intentional joint attention is a basic joint action. Furthermore, we discuss the functional role of intentional joint attention for successful cooperation in complex joint actions.

Amidst the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. Some support a correlation of conscious perception with early occipital events, others with late parieto-frontal activity. Here we attempt to make sense of those dissenting results. On the basis of a minimal neuro-computational model, the global neuronal workspace hypothesis, we propose a (...) taxonomy which distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing. We suggest that these distinctions map onto different neural mechanisms, and that conscious perception is systematically associated with a sudden surge of parieto-frontal activity causing top-down amplification.

The present paper considers the question whether, and if so how, a subject's full attention to an object which she interacts with might have value. More specifically, I defend the claim that in order for a subject's activity to have value, it is sufficient that the subject give her full attention to the object towards which the activity is directed.

Peak human performance—whether of Olympic athletes, Nobel prize winners, or you cooking the best dish you’ve ever made—depends on skill. Skill is at the heart of what it means to excel. Yet, the fixity of skilled behavior can sometimes make it seem a lower-level activity, more akin to the movements of an invertebrate or a machine. Peak performance in elite athletes is often described, for example, as “automatic” by those athletes: “The most frequent response from participants when describing the execution (...) of a peak performance was the automatic execution of performance”. While the automaticity of skilled behavior is widely acknowledged, some worry that too much automaticity in skill would challenge its ability to exhibit human excellence. And so two camps have developed: those who focus on the automaticity of skilled behavior, the “habitualists,” and those who focus on the higher-level cognition behind peak performance, the “intellectualists.” We take a different tack. We argue that skilled behavior weaves together automaticity and higher-level cognition, which we call “pluralism.” That is, we argue that automaticity and higher-level cognition are both normal features of skilled behavior that benefit skilled behavior. This view is hinted at in other quotes about automaticity in skill—while expert gamers describe themselves as “playing with” automaticity, expert musicians are said to balance automaticity with creativity through performance cues: “Performance cues allow the musician to attend to some aspects of the performance while allowing others to be executed automatically”. We describe in this paper three ways that higher-level cognition and automaticity are woven together. The first two, level pluralism and synchronic pluralism, are described in other papers, albeit under different cover. We take our contribution to be both distinguishing the three forms and contributing the third, diachronic pluralism. In fact, we find that diachronic pluralism presents the strongest case against habitualism and intellectualism, especially when considered through the example of strategic automaticity. In each case of pluralism, we use research on the presence or absence of attention to explore the presence or absence of higher-level cognition in skilled behavior. (shrink)

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

The use of forward models is well established in cognitive and computational neuroscience. We compare and contrast two recent, but interestingly divergent, accounts of the place of forward models in the human cognitive architecture. On the Auxiliary Forward Model account, forward models are special-purpose prediction mechanisms implemented by additional circuitry distinct from core mechanisms of perception and action. On the Integral Forward Model account, forward models lie at the heart of all forms of perception and action. We compare these neighbouring (...) but importantly different visions and consider their implications for the cognitive sciences. We end by asking what kinds of empirical research might offer evidence favouring one or the other of these approaches. (shrink)

John Campbell investigates how consciousness of the world explains our ability to think about the world; how our ability to think about objects we can see depends on our capacity for conscious visual attention to those things. He illuminates classical problems about thought, reference, and experience by looking at the underlying psychological mechanisms on which conscious attention depends.
