In this book, Michael Madary examines visual experience, drawing on both phenomenological and empirical methods of investigation. He finds that these two approaches—careful, philosophical description of experience and the science of vision—independently converge on the same result: Visual perception is an ongoing process of anticipation and fulfillment. Madary first makes the case for the descriptive premise, arguing that the phenomenology of vision is best described as on ongoing process of anticipation and fulfillment. He discusses visual experience as (...) being perspectival, temporal, and indeterminate; considers the possibility of surprise when appearances do not change as we expect; and considers the content of visual anticipation. Madary then makes the case for the empirical premise, showing that there are strong empirical reasons to model vision using the general form of anticipation and fulfillment. He presents a range of evidence from perceptual psychology and neuroscience, and reinterprets evidence for the two-visual-systems hypothesis. Finally, he considers the relationship between visual perception and social cognition. An appendix discusses Husserlian phenomenology as it relates to the argument of the book. Madary argues that the fact that there is a convergence of historically distinct methodologies itself is an argument that supports his findings. With Visual Phenomenology, he creates an exchange between the humanities and the sciences that takes both methods of investigation seriously. (shrink)

The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that (...) one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go on to discuss recent evidence indicating that immersion in VR can have psychological effects that last after leaving the virtual environment. In the second part of the article, we turn to the risks and recommendations. We begin, in Section “The Research Ethics of VR,” with the research ethics of VR, covering six main topics: the limits of experimental environments, informed consent, clinical risks, dual-use, online research, and a general point about the limitations of a code of conduct for research. Then, in Section “Risks for Individuals and Society,” we turn to the risks of VR for the general public, covering four main topics: long-term immersion, neglect of the social and physical environment, risky content, and privacy. We offer concrete recommendations for each of these 10 topics, summarized in Table 1. (shrink)

The first part of this article makes the case that human cognition is an intergenerational project enabled by the inheritance and bequeathal of cognitive technology (Sects. 2–4). The final two sections of the article (Sects. 5 and 6) explore the normative significance of this claim. My case for the intergenerational claim draws results from multiple disciplines: philosophy (Sect. 2), cultural evolutionary approaches in cognitive science (Sect. 3), and developmental psychology and neuroscience (Sect. 4). In Sect. 5, I propose that cognitive (...) technology should be given to future generations in accordance with principles of pluralism and transparency. In the final main section of the article, Sect. 6, I apply these principles to topics such as the preservation of information, environmental offloading of cognition, and thinking itself. (shrink)

Abstract: In philosophy, perceptual constancy refers to the puzzling phenomenon of the perception of properties of objects despite our changing experience of those properties. Husserl developed a sophisticated description of perceptual constancy. In this paper I sketch Husserl's approach, which focuses on the suggestion that perception is partly constituted by the continuous interplay of intention and fulfilment. Unlike many contemporary theories, this framework gives us a way to understand the relationship between different appearances of the same object. I will show (...) how Husserl's work connects with contemporary theories which emphasize perceptual constancy from particular perspectives. These theories include appeals to perspectival properties and Cohen's counterfactual theory. Also, I show how Husserl's account shares important themes with Kelly's recent interpretation of Merleau-Ponty on perceptual constancy. (shrink)

This article makes the case that our digital devices create illusions of agency. There are times when users feel as if they are in control when in fact they are merely responding to stimuli on the screen in predictable ways. After the introduction, the second section of the article offers examples of illusions of agency that do not involve human–computer interaction in order to show that such illusions are possible and not terribly uncommon. The third and fourth sections of the (...) article cover relevant work from empirical psychology, including the cues that are known to generate the sense of agency. The fifth section of the article shows that our devices are designed to deliver precisely those cues. In the sixth section, the argument is completed with evidence that users frequently use their smartphones without the sort of intentional supervision involved in genuine agency. This sixth section includes the introduction of Digital Environmental Dependency Syndrome (DEDS) as a possible way of characterizing extended use of the smartphone without genuine agency. In the final section of the article, there is a discussion of questions raised by the main claim, including suggestions for reducing occurrences of illusions of agency through software design.

This article is composed of three parts. In the first part of the article I take up a question raised by Susanna Siegel (Philosophical Review 115: 355–388, 2006a). Siegel has argued that subjects have the following anticipation: (PC) If S substantially changes her perspective on o, her visual phenomenology will change as a result of this change. She has left it an open question as to whether subjects anticipate a specific kind of change. I take up this question and answer (...) it in the affirmative. By appealing to a widely held view of perceptual content, the view that we represent ‘factual’ properties in perception, I argue that (PC) can be refined as follows: (PC’) If S substantially changes her perspective on o, her visual phenomenology will present different views of o’s factual properties. In the second part of the article I argue that (PC’) implies that there are cases in which normal perceivers have different perceptual content under identical viewing conditions. The differences in perceptual content are due to differences in the determinacy of visual anticipation. I draw the conclusion that perceptual content is rich in the sense that it includes a unique contribution from individual perceivers. In the final part of the article, I discuss some open issues regarding the way in which (PC’) relates to the personal/sub-personal distinction, empirical models, and the distinction between perception and cognition.

Today many philosophers of mind accept that the two cortical streams of visual processing in humans can be distinguished in terms of conscious experience. The ventral stream is thought to produce representations that may become conscious, and the dorsal stream is thought to handle unconscious vision for action. Despite a vast literature on the topic of the two streams, there is currently no account of the way in which the relevant empirical evidence could fit with basic Husserlian phenomenology of vision. (...) Here I offer such an account. In this article, I show how the empirical evidence ought to be understood in a way that is informed by phenomenology. The differences in the two streams are better described as differences in spatial and temporal processing. Rather than simply “unconscious,” the dorsal stream can be better described as making a special contribution to what Husserl identified as the visual horizon. (shrink)

In this article I raise empirical challenges for the claim tha area MT/V5 is the neural correlate for visual experience as of motion (Block 2005). In particular, I focus on the claim that there is matching content between area MT, on one hand, and visual experience as of motion, on the other hand (Chalmers 2000, Block 2007). I survey two lines of empirical evidence which challenge the claim of matching content in area MT. The first line of evidence covers new (...) results in neuroscience which emphasize the ongoing dynamics in cortical activity. The second line of evidence focuses on results regarding area MT in particular (Maier et al. 2007 and Cohen and Newsome 2008). Together, the empirical results indicate that neural processing is context sensitive in a way that challenges the attribution of content to local areas of cortex, to area MT in particular. In the final part of the article I explore alternative approaches and discuss remaining issues. (shrink)

This article is a contribution to a recent debate in the philosophy of perception between Alva Noë and Sean Kelly. Noë (2004) has argued that the perspectival part of perception is simultaneously represented along with the non-perspectival part of perception. Kelly (2004) argues that the two parts of perception are not always simultaneously experienced. Here I focus on specular highlights as an example of the perspectival part of perception. First I give a priori motivation to think that specular highlights are (...) experienced at the same time as non-perspectival properties, which challenges Kelly's position. Then I discuss psychophysical work by Andrew Blake and Heinrich B lthoff (1990) which seems to show that specular highlights are not represented in the way that Noë (2004) would suggest. In the third section I suggest a compromise between Noë and Kelly: specular highlights are not represented, but rather play an evidentiary role in the representation of perspective-independent properties, like gloss and shape. I conclude with some thoughts about how this study can generalize to other kinds of experience. (shrink)

Vehicle externalists hold that the physical substrate of mental states can sometimes extend beyond the brain into the body and environment. In a particular variation on vehicle externalism, Susan Hurley (1998) and Alva Noë (2004) have argued that perceptual states, states with phenomenal qualities, are among the mental states that can sometimes spread beyond the brain. Their vehicle externalism about perceptual states will be the main topic of this article. In particular, I will address three strong objections to their vehicle (...) externalism, objections by Ned Block (2005), Jesse Prinz (2006), and Fred Adams & Ken Aizawa (2008). Though in some ways these objections appear disparate, I will argue that all of them depend on a crucial presupposition, one which Hurley, Noë, and their sympathizers should reject. This presupposition is that perceptual character is fixed by an instantaneous snapshot of neural states, a view that Hurley dubbed ‘temporal atomism.’ To put the presupposition in more familiar terms, all three objections are implicitly committed to something like Dennett’s Cartesian Theater (1991). -/- In the first part of the article, I will discuss Hurley and Noë’s views, and include reasons why their views entail the rejection of the Cartesian Theater. In the next part of the article I will introduce the three objections and show how they presuppose something like a Cartesian Theater. I will also show that, if the Cartesian Theater is rejected, the objections all vanish. In the final part of the article I address the charge that Noë and Hurley confuse causation with constitution. This charge reveals a lack of appreciation for the way in which dynamical explanation motivates Hurley’s externalism. (shrink)

Here is an old philosophical puzzle. Take out a coin and look at it. It is a flat disk. Now tilt it so that you look at it on an angle. From an angle, there is some sense in which the tilted coin appears elliptical. But there is also a strong sense in which the tilted coin looks circular, like a flat disk. How can one object look both elliptical and circular at the same time? Thus, the puzzle of the (...) tilted coin. (shrink)

In this commentary, I suggest that non-visual perceptual modalities provide counterexamples to Seth’s claim that perceptual presence depends on counterfactual richness. Then I suggest a modification to Seth’s view that is not vulnerable to these counterexamples.

This article offers an analysis of intentionality for virtual objects and explores some of the ethical implications of this analysis. The main example which serves as a motivation for the article is the case of a Chinese gamer who, in 2005, committed murder in retaliation for the theft of a virtual object, the theft of his virtual dragon sabre. The intentional analysis reveals that the way in which we experience virtual objects shares a structural similarity with the way in which (...) we experience physical objects. Both virtual and physical objects are accessible through action and intersubjectively available. The final part of the article introduces three ethical points based on the intentional analysis. First, virtual objects can have the same ethical significance as physical objects. Second, it will be important to consider empirical results on the factors which influence one’s subjective level of immersion in the virtual world. Finally, the intentional analysis of virtual objects suggests specific questions for future research. (shrink)

What is the relationship between perception and action, between an organism and its environment, in explaining consciousness? These are issues at the heart of philosophy of mind and the cognitive sciences. This book explores the relationship between perception and action from a variety of interdisciplinary perspectives, ranging from theoretical discussion of concepts to findings from recent scientific studies. It incorporates contributions from leading philosophers, psychologists, neuroscientists, and an artificial intelligence theorist. The contributions take a range of positions with respect to (...) the view that perception is an achievement by an agent acting in a complex environment in which sensorimotor dynamics constitute an essential ingredient to perceptual experience. A key focus of the book is on the debate about action-oriented theories of visual perception versus the dual-visual systems hypothesis The former champions the role of sensorimotor dynamics in perceptual awareness while the latter favours a functional dichotomy between perception and action. At least on the surface, these two approaches are in conflict. Where one emphasizes the interdependence of action and perception, the other suggests that action and perception are functionally distinct. The dialogue between these two approaches brings out wider theoretical issues underlying the research paradigm of cognitive sciences and philosophy of mind. Exploring one of the major debates in the philosophy and psychology, this book is fascinating reading for all those in the cognitive sciences and philosophy of mind. (shrink)

This book is an interdisciplinary exploration of the relationship between perception and action, with a focus on the debate about the dual visual systems hypothesis, against action oriented theories of perception.

One of the latest labels to emerge for anti-classical cognitive science is “4E.” The four Es here are the embodied, embedded, enacted, and extended approaches to cognition. Since there are a number of different, and likely incompatible, lines of thought within the 4E group, more work needs to be done to articulate how the Es can and should fit together. Mark Rowlands’ newest book, The New Science of the Mind: From Extended Mind to Embodied Phenomenology, addresses this need in a (...) valuable way. He argues, clearly and carefully, for the thesis of the amalgamated mind, which “subsumes both theses of the embodied and the extended mind” . The thesis of the embedded mind is rejected as being merely a claim about cognition depending causally on the environment. As such, it is not strong enough to be interesting for Rowlands’ non-Cartesian project. The thesis of the enacted mind, in particular Alva Noë’s sensorimotor version of it, is also rejected as being either implausible or no stronger than the thesis of the embedded mind . First I will outline Rowlands’ defense of the thesis of the amalgamated mind; then I will raise some issues for further investigation. (shrink)

The study of perception and the role of the senses have recently risen to prominence in philosophy and are now a major area of study and research. However, the philosophical history of the senses remains a relatively neglected subject. Moving beyond the current philosophical canon, this outstanding collection offers a wide-ranging and diverse philosophical exploration of the senses, from the classical period to the present day. Written by a team of international contributors, it is divided into six parts: -/- Perception (...) from Non-Western Perspectives Perception in the Ancient Period Perception in the Medieval Latin/Arabic Period Perception in the Early Modern Period Perception in the Post-Kantian Period Perception in the Contemporary Period. The volume challenges conventional philosophical study of perception by covering a wide range of significant, as well as hitherto overlooked, topics, such as perceptual judgment, temporal and motion illusions, mirror and picture perception, animal senses and cross-modal integration. By investigating the history of the senses in thinkers such as Plotinus, Auriol, Berkeley and Cavendish; and considering the history of the senses in diverse philosophical traditions, including Chinese, Indian, Byzantine, Greek and Latin it brings a fresh approach to studying the history of philosophy itself. -/- Including a thorough introduction as well as introductions to each section by the editors, The Senses and the History of Philosophy is essential reading for students and researchers in the history of philosophy, perception, philosophy of mind, philosophical psychology, aesthetics and eastern and non-western philosophy. It will also be extremely useful for those in related disciplines such as psychology, religion, sociology, intellectual history and cognitive sciences. (shrink)

A review of Michael Madary's book Visual Phenomenology.

Review of Michael Madary's book *Visual Phenomenology* MIT Press, 2016.

In his remarkable book, Visual Phenomenology, Michael Madary argues for the claim that “visual perception is an ongoing process of anticipation and fulfillment” (Madary 2017, p. 3), by drawing upon lines of evidence from Husserlian phenomenology, philosophy of perception, and the cognitive sciences. While he considers Edmund Husserl as a major influence upon his ideas, he does not aim to adhere to Husserl’s views in every regard, but instead to develop Husserl-inspired views of his own, muster support (...) for them, and bring them to bear on various issues (Ibid., pp. 4, 181). His book is therefore likely to be of interest not only to scholars of Husserlian phenomenology, but also to non-Husserlian philosophers of perception, as well as to cognitive scientists. (shrink)

According to the received account of guilt in the philosophical literature, one cannot feel guilt unless one takes oneself to have done something morally wrong. But ordinary people feel guilt in many cases in which they do not take themselves to have done anything morally wrong. In this paper, I focus on one kind of guilt without perceived wrongdoing, guilt about being merely causally responsible for a bad state-of-affairs. I go on to present a novel account of guilt that explains (...) guilt about mere causal responsibility, according to which guilt represents part of the self as bound up with what is bad. (shrink)

An Essay on Human Action seeks to provide a comprehensive, detailed, enlightening, and (in its detail) original account of human action. This account presupposes a theory of events as abstract, proposition-like entities, a theory which is given in the first chapter of the book. The core-issues of action-theory are then treated: what acting in general is (a version of the traditional volitional theory is proposed and defended); how actions are to be individuated; how long actions last; what acting intentionally is; (...) what doing one thing by doing another is; what basic action is; and what omitting to do something is. Attention is also given to the concepts of causation, intention, volition, deciding, choosing, and trying. Finally, a libertarian account of free action is tentatively proposed and defended.

Our aim in this paper is to present the distinct ways in which Wolff, Baumgarten, and Kant understand the relationship between necessitation, constraint, and reluctant action in an effort to illustrate the subtle ways in which their conceptions of obligation differ from each another. Whereas Wolff conceives of natural or moral obligation as incompatible with constraint, Baumgarten holds that constraint and reluctant action are, in some instances, compatible with natural obligation. Kant departs from Baumgarten by conceiving of obligation as necessarily (...) involving constraint: as Kant’s reply to Schiller’s famous objection reveals, obligation must take on the character of constraint to reluctant action on account of the fact that human beings possess inclinations that always threaten to impel them in directions that oppose morality.

What is the relation between small-scale collaborative plans and the execution of those plans within interactive contexts? I argue here that joint attention has a key role in explaining how shared plans and shared intentions are executed in interactive contexts. Within singular action, attention plays the functional role of enabling intentional action to be guided by a prior intention. Within interactive joint action, it is joint attention, I argue, that plays a similar functional role of enabling the agents to act (...) in a collaborative way such that their actions are rationally guided by a prior shared intention. This understanding of joint attention – as having a key functional role of enabling the rational guidance of joint intentional action by a prior shared intention – allows for an alternative understanding of the kind of minimal cooperation that infants can engage in. On this understanding, infants’ capacity to engage in joint actions is already an incipient capacity to engage in rational and intentional joint actions, albeit a capacity that is necessarily scaffolded by an adult rational co-partner.

Common knowledge is ubiquitous in our lives and yet there remains considerable uncertainty about how to model or understand it. Standard analyses of common knowledge end up being challenged by either regress or circularity which then give rise to well-known paradoxes of practical reasoning, such as the Two Generals’ Paradox. This paper argues that the nature and utility of common knowledge can be illuminated by appeal to Wittgenstein’s Hinge Epistemology. It is argued that those things that we standardly think of (...) as being common knowledge in our lives are the same as those that Wittgenstein identified as hinge certainties. This identification of common knowledge with hinge certainties allows us to resolve the regress problem for common knowledge and explain how the Two Generals’ Paradox arises. (shrink)

It is a commonplace in economics that we should disregard sunk costs. The sunk cost effect might be widespread, goes the conventional wisdom, but we would be better off if we could rid ourselves of it. In this paper, I argue against the orthodoxy by showing that the sunk cost effect is often beneficial. Drawing on discussions of related topics in dynamic choice theory, I show that, in a range of cases, being disposed to honor sunk costs allows an agent (...) to mimic a resolute chooser, someone who adopts the best plan at the outset of a decision problem and sticks with it, even when resoluteness is unfeasible. I discuss several kinds of cases in which honoring sunk costs coincides with resolute choice. (shrink)

What is the relation between joint attention and common knowledge? On the one hand, the relation seems tight: the easiest and most reliable way of knowing something in common with another is for you and that other to be attentively aware of what you are together experiencing. On the other hand, they couldn’t seem further apart: joint attention is a mere perceptual phenomena that infants are capable of engaging in from nine months of age, whereas common knowledge is a cognitive (...) phenomenon involving (so it seems) complex, overlapping metarepresentational states that require the kind of sophisticated mindreading skills that developmental psychology has shown to be beyond the capabilities of young children. In 'The Shared World: Perceptual Common Knowledge, Demonstrative Communication, and Shared Social Space', Axel Seemann attempts, inter alia, to makensense of this conundrum. (shrink)

Using William Shakespeare’s Hamlet and the play-within-the play, The Murder of Gonzago, as a case study, this essay argues that theatrical utterances constitute a special case of language usage not previously elucidated: the utterance of a statement with propositional content in theatre functions as an event. In short, the propositional content of a particular p (e.g. p1, p2, p3 …), whether or not it is true, is only understood—and understood to be true—if p1 is uttered in a particular time, place, (...) and situation (i.e. during a theatrical event); otherwise, the propositional content in those theatrical utterances can either be false or contingently true.

A particular feature of this book is substantial "Stretch and Challenge" material throughout which allows students to develop further.

Concepts and Cases in Nursing Ethics is an introduction to contemporary ethical issues in health care, designed especially for Canadian audiences. The book is organized around six key concepts: beneficence, autonomy, truth-telling, confidentiality, justice, and integrity. Each of these concepts is explained and discussed with reference to professional and legal norms. The discussion is then supplemented by case studies that exemplify the relevant concepts and show how each applies in health care and nursing practice. This new fourth edition includes an (...) added chapter on end-of-life issues, and it is revised throughout to reflect the latest developments on topics such as global health ethics, cultural competence, social media, and palliative sedation.

Als Philosoph, Literat, Prediger und Pädagoge gehört Herder zu den bedeutendsten Vertretern der Weimarer Klassik. Diese aktuelle und kenntnisreiche Biografie bringt Leben und Werk Herders einem breiteren Publikum nahe.

Concepts and Cases in Nursing Ethics maps the ethical landscape of contemporary nursing. The book is the product of a collaboration between philosopher-ethicist Michael Yeo, nurse-ethicist Anne Moorhouse, and six representatives of various areas of professional nursing. It thus combines philosophical and ethical analysis with nursing knowledge and experience in a manner that is both understandable and relevant. The book is organized around six main concepts in nursing ethics: beneficence, autonomy, confidentiality, truth-telling, justice, and integrity. A chapter is devoted (...) to the elucidation of each of these concepts. In each chapter, historical background and conceptual analysis are supplemented by case studies that exemplify issues and show how the concept applies in nursing practice. In this new edition, the materials in each chapter have been updated to reflect recent developments in nursing and more generally in health care. In addition, a totally new chapter on ethical theory has been added. Complete with bibliographies and study questions for further analysis of cases, this book is ideally suited for textbook use. It will help both practitioners and students to deal better with the clinical problems and issues that are encountered in the field. However, it's simple prose and clear exposition of complex issues will make Concepts and Cases in Nursing Ethics attractive to anyone concerned about health care. (shrink)
