Our ability to acknowledge and recognise our own identity - our 'self' - is a characteristic doubtless unique to humans. Where does this feeling come from? How does the combination of neurophysiological processes coupled with our interaction with the outside world construct this coherent identity? We know that our social interactions contribute via the eyes, ears etc. However, our self is not only influenced by our senses. It is also influenced by the actions we perform and those we see others (...) perform. Our brain anticipates the effects of our own actions and simulates the actions of others. In this way, we become able to understand ourselves and to understand the actions and emotions of others. -/- This book is the first to describe the new field of 'Motor Cognition' - one to which the author's contribution has been seminal. Though motor actions have long been studied by neuroscientists and physiologists, it is only recently that scientists have considered the role of actions in building the self. How consciousness of action is part of self-consciousness, how one's own actions determine the sense of being an agent, how actions performed by others impact on ourselves for understanding others, differentiating ourselves from them and learning from them: these questions are raised and discussed throughout the book, drawing on experimental, clinical, and theoretical bases. -/- The advent of new neuroscience techniques, like neuroimaging and direct electrical brain stimulation, together with a renewal of behavioral methods in cognitive psychology, provide new insights into this area. Mental imagery of action, self-recognition, consciousness of actions, imitation can be objectively studied using these new tools. The results of these investigations shed light on clinical disorders in neurology, psychiatry and in neuro-development. -/- This is a major new work that will lay down the foundations for the field of motor cognition.

This paper concerns how motor actions are neurally represented and coded. Action planning and motor preparation can be studied using a specific type of representational activity, motor imagery. A close functional equivalence between motor imagery and motor preparation is suggested by the positive effects of imagining movements on motor learning, the similarity between the neural structures involved, and the similar physiological correlates observed in both imaging and preparing. The content of motor representations can be inferred from motor images at a (...) macroscopic level, based on global aspects of the action and the motor rules and constraints which predict the spatial path and kinematics of movements. A more microscopic neural account calls for a representation of object-oriented action. Object attributes are processed in different neural pathways depending on the kind of task the subject is performing. During object-oriented action, a pragmatic representation is activated in which object affordances are transformed into specific motor schemas. Animal as well as human clinical data implicate the posterior parietal and premotor cortical areas in schema instantiation. A mechanism is proposed that is able to encode the desired goal of the action and is applicable to different levels of representational organization. (shrink)

This paper is concerned with the problem of selfidentification in the domain of action. We claim that this problem can arise not just for the self as object, but also for the self as subject in the ascription of agency. We discuss and evaluate some proposals concerning the mechanisms involved in selfidentification and in agencyascription, and their possible impairments in pathological cases. We argue in favor of a simulation hypothesis that claims that actions, whether overt or covert, are centrally simulated (...) by the neural network, and that this simulation provides the basis for action recognition and attribution.

According to the two visual systems model, the visual processing of objects divides into semantic and pragmatic processing. We provide various criteria for this distinction. Further, we argue that both the semantic and pragmatic processing of visual information about objects should be divided into low-level processing and high-level processing. Finally, we re-evaluate the contribution of the human parietal lobe to the concious visual perception of spatial relations among objects.

This paper offers a framework for consciousness of internal reality. Recent PET experiments are reviewed, showing partial overlap of cortical activation during self-produced actions and actions observed from other people. This overlap suggests that representations for actions may be shared by several individuals, a situation which creates a potential problem for correctly attributing an action to its agent. The neural conditions for correct agency judgments are thus assigned a key role in self/other distinction and self-consciousness. A series of behavioral experiments (...) that demonstrate, in normal subjects, the poor monitoring of action-related signals and the difficulty in recognizing self-produced actions are described. In patients presenting delusions, this difficulty dramatically increases and actions become systematically misattributed. These results point to schizophrenia and related disorders as a paradigmatic alteration of a ''Who?'' system for self-consciousness. (shrink)

This chapter examines what constitutes an “action” and then focuses on simple actions that provide insight into the complex overt and covert processes required to generate them. It considers the contrast between non‐conscious, automatic actions and conscious, controlled ones and analyses the components of controlled actions that are accessible or inaccessible to consciousness. On the basis of experimental and clinical evidence the chapter then develops a model of the neurophysiological processes involved in action recognition and concludes with an evaluation of (...) conscious agency being, in some respects, “an illusion”.

Marc Jeannerod and I wrote a Précis of our 2003 book Ways of Seeing. The journal Dialogue asked Tim Schroeder, Alva Noë, Pierre Poirier and Martin Ratte to write a critical essay on our book. In this piece, we reply to our critics.

This is a summary of the book Ways of Seing co-authord witth Marc Jeannerod and published by Oxford University Press in 2003.

Ways of Seeing is a unique collaboration between an eminent philosopher and a world famous neuroscientist. It focuses on one of the most basic human functions - vision. What does it mean to 'see'. It brings together electrophysiological studies, neuropsychology, psychophysics, cognitive psychology, and philosophy of mind. The first truly interdisciplinary book devoted to the topic of vision, it will make a valuable contribution to the field of cognitive science.

Recent experiments in normal subjects using neuroimaging demonstrate that the dorsal cortico-cortical pathway is involved during purely perceptual activities. Pathological cases with right posterior parietal lesions show deficits in visuospatial perception. It is argued that the radical dichotomy between perception and action pathways, as heralded in Milner and Goodale's book should be reexamined. The idea of distributed networks using resources in both visual pathways and recruited as a function of task demands is presented.

La plupart de nos actions sont exécutées sous le contrôle de mécanismes automatiques. Le sentiment d'avoir volontairement causé une action et, par extension, la conscience de soi relèvent de mécanismes antérieurs au sentiment qu'ils causent, antériorité fondée sur la lenteur des processus aboutissant à l'expérience consciente. La conscience n'a done pas de rôle causal immédiat sur l'activité nerveuse ni sur le comportement, elle intervient a posteriori pour structurer le moi cognitif et maintenir l'unité du moi. Most of our actions are (...) executed under the control of automatic mechanisms. The feeling one has to have willingly caused an action and — by extension — selfconsciousness, refer to the mechanisms prior to the feeling it lead to, i.e. a precedence resting on the slowness of processes leading to a conscious experience. Consciousness thus seems to have no immediate causal part to play on the nervous activity neither on behaviour, it interferes only later in order to structure the cognitive ego and keep some cohesiveness to the ego.

Marc Jeannerod is director of the Institut des Sciences Cognitives in Lyon. His work in neuropsychology focuses on motor action. The idea that there is an essential relationship between bodily movement, consciousness, and cognition is not a new one, but recent advances in the technologies of brain imaging have provided new and detailed support for understanding this relationship. Experimental studies conducted by Jeannerod and his colleagues at Lyon have explored the details of brain activity, not only as (...) we are actively moving, but as we plan to move, as we imagine moving, and as we observe others move. His work also captures important distinctions between pathological and non-pathological experience. In The Cognitive Neuroscience of Action , Jeannerod focussed on object-oriented actions. What happens in the brain and what do we experience when we reach to grasp an object? How do we plan an action of that sort? To what extent does explicit motor imagery contribute to such action? What role does a motor representation or motor schema play in the accomplishment of action? At the very end of that book he raises questions that seem quite different. How is it possible to understand the intentions of others? Precisely what mechanisms allow us to imitate other people's actions? In more recent years much of Jeannerod's work has been in pursuit of these questions about interaction with others, and he has helped to show that there are intimate connections between moving ourselves and understanding others. Jeannerod's work does not lack important implications for a philosophical understanding of human activity. Although in contemporary philosophical debates on consciousness one can still find arguments that simply ignore bodily movement as an important factor in cognition, several recent works have returned to serious consideration of movement and action . In the following interview Jeannerod discusses many issues relevant to the philosophy of mind and action, including concepts of intentionality, movement and consciousness of movement, the role of simulation in understanding others, and the best way to conceptualize brain processes in all of these regards. Importantly, he makes constant reference to the empirical evidence, much of it developed in his own experimental studies. (shrink)

Recent advances in the cognitive neuroscience of action have considerably enlarged our understanding of human motor cognition. In particular, the activity of the mirror system, first discovered in the brain of non-human primates, provides an observer with the understanding of a perceived action by means of the motor simulation of the agent's observed movements. This discovery has raised the prospects of a motor theory of social cognition. Since human social cognition includes the ability to mindread, many motor theorists of social (...) cognition try to bridge the gap between motor cognition and mindreading by endorsing a simulation account of mindreading. Here, we express our skepticism about the motor theory of social cognition. (shrink)

The abilities to attribute an action to its proper agent and to understand its meaning when it is produced by someone else are basic aspects of human social communication. Several psychiatric syndromes, such as schizophrenia, seem to lead to a dysfunction of the awareness of one’s own action as well as of recognition of actions performed by other. Such syndromes offer a framework for studying the determinants of agency, the ability to correctly attribute actions to their veridical source. Thirty normal (...) subjects and 30 schizophrenic patients with and without hallucinations and/or delusional experiences were required to execute simple finger and wrist movements, without direct visual control of their hand. The image of either their own hand or an alien hand executing the same or a different movement was presented on a TV-screen in real time. The task for the subjects was to discriminate whether the hand presented on the screen was their own or not. Hallucinating and deluded schizophrenic patients were more impaired in discriminating their own hand from the alien one than the non-hallucinating ones, and tended to misattribute the alien hand to themselves. Results are discussed according to a model of action control. A tentative description of the mechanisms leading to action consciousness is proposed. (shrink)

This is the first chapter of Ways of Seeing co-authored with Marc Jeannerod. We ague for a representational approach to the puzzles of both visual perception and visually-guided actions.

Human vision raises a number of puzzles. Among them are the puzzles of visual experience: how to provide a scientific understanding of the phenomenal character of the visual experiences of the shapes, textures, colors, orientations and motion of perceived objects? How can a purely subjective visual experience be the basis of so much objective knowledge of the world? Visually guided actions raise a different puzzle: how can actions directed towards a target be so accurate in the absence of the agent’s (...) awareness of many of the target’s visual attributes? Ways of Seeing has three related goals, the first of which is to make the case for a broadly representational approach to the above set of puzzles. The second goal of WoS is to argue that the version of the ‘two-visual systems’ model of human vision best supported by the current empirical evidence has the resources to solve the puzzle of visually guided actions, which has been at the center of much recent work in the cognitive neuroscience of vision and action. The third goal of WoS is to draw attention to some of the tensions between acceptance of the two-visual systems model of human vision and some influential views about the nature and function of the content of visual experience espoused by philosophers in response to the puzzles raised by visual experience.

Why do forces compose according to the parallelogram of forces? This question has been controversial; it is one episode in a longstanding, fundamental dispute regarding which facts are not to be explained dynamically. If the parallelogram law is explained statically, then the laws of statics are separate from and “transcend” the laws of dynamics. Alternatively, if the parallelogram law is explained dynamically, then statical laws become mere corollaries to the dynamical laws. I shall attempt to trace the history of this (...) controversy in order to identify what it would be for one or the other of these rival views to be correct. I shall argue that various familiar accounts of natural law not only make it difficult to see what the point of this dispute could have been, but also improperly foreclose some serious scientific options. I will sketch an alternative account of laws that helps us to understand what this dispute was all about. (shrink)

It has often been argued that Humean accounts of natural law cannot account for the role played by laws in scientific explanations. Loewer (Philosophical Studies 2012) has offered a new reply to this argument on behalf of Humean accounts—a reply that distinguishes between grounding (which Loewer portrays as underwriting a kind of metaphysical explanation) and scientific explanation. I will argue that Loewer’s reply fails because it cannot accommodate the relation between metaphysical and scientific explanation. This relation also resolves a puzzle (...) about scientific explanation that Hempel and Oppenheim (Philosophy of Science 15:135–75, 1948) encountered. (shrink)

Conflicts of interest are rampant in the American medical community. Today it is not uncommon for doctors to refer patients to clinics or labs in which they have a financial interest (40% of physicians in Florida invest in medical centers); for hospitals to offer incentives to physicians who refer patients (a practice that can lead to unnecessary hospitalization); or for drug companies to provide lucrative give-aways to entice doctors to use their "brand name" drugs (which are much more expensive than (...) generic drugs). In Medicine, Money and Morals, Marc A. Rodwin draws on his own experience as a health lawyer--and his research in health ethics, law, and policy--to reveal how financial conflicts of interest can and do negatively affect the quality of patient care. He shows that the problem has become worse over the last century and provides many actual examples of how doctors' decisions are influenced by financial considerations. We learn how two California physicians, for example, resumed referrals to Pasadena General Hospital only after the hospital started paying $70 per patient (their referrals grew from 14 in one month to 82 in the next). As Rodwin writes, incentives such as this can inhibit a doctor from taking action when a hospital fails to provide proper service, and may also lead to the unnecessary hospitalization of patients. We also learn of a Wyeth-Ayerst Labs promotion in which physicians who started patients on INDERAL (a drug for high blood pressure, angina, and migraines) received 1000 mileage points on American Airlines for each patient (studies show that promotions such as this have a direct effect on a doctor's choice of drug). Rodwin reveals why the medical community has failed to regulate conflicts of interest: peer review has little authority, state licensing boards are usually ignorant of abuses, and the AMA code of ethics has historically been recommended rather than required. He examines what can be learned from the way society has coped with the conflicts of interest of other professionals --lawyers, government officials, and businessmen--all of which are held to higher standards of accountability than doctors. And he recommends that efforts be made to prohibit and regulate certain kinds of activity (such as kickbacks and self-referrals), to monitor and regulate conduct, and to provide penalties for improper conduct. Our failure to face physicians' conflicts of interest has distorted the way medicine is practiced, compromised the loyalty of doctors to patients, and harmed society, the integrity of the medical profession, and patients. For those concerned with the quality of health care or medical ethics, Medicine, Money and Morals is a provocative look into the current health care crisis and a powerful prescription for change.

Structural requirements of rationality prohibit various things, like having inconsistent combinations of attitudes, having means-end incoherent combinations of attitudes, and so on. But what is the distinctive feature of structural requirements of rationality? And do we fall under an obligation to be structurally rational? These issues have been at the heart of significant debates over the past fifteen years. Some philosophers have recently argued that we can unify the structural requirements of rationality by analyzing what is constitutive of our attitudes (...) (Lee, 2020; Worsnip, 2018a). It has also been suggested that, in the course of good first-personal deliberation, agents should treat structurally irrational combinations of attitudes as off-limits (Worsnip, 2021). In this paper, I raise a worry for these two theses concerning structural rationality. Roughly, I argue that some imperfect epistemic agents (like us) can be disposed to have structurally irrational combinations of attitudes. Also, when these imperfect agents deliberate, they should not treat structurally irrational combinations of attitudes as off-limits. Given our imperfections, being structurally irrational can very well be the best option we have. More generally, these observations reveal that structural rationality should not always be theorized independently from more “substantive” norms, like responsiveness to reasons or expected value optimization.

The article « La Défenestration » by Belgian philosopher Marc Richir has been translated into Russian for the first time for this issue of the “Horizon. Studies in Phenomenology.” In his early work “The Defenestration” Richir raises the question of relation between the subject and conceivable world. Here, a philosopher is pictured contemplating the world through the window of his tower. In such detachment from the world the thinker finds himself according to all Modern philosophies of consciousness. Husserl’s phenomenology (...) inherits this detachment, since Husserl imposes the structure of transcendental ego as external to the world. Richir abolishes the concept of transcendental ego with the help of heideggerian Dasein, but analyzing Heidegger’s ontology he comes to the conclusion that the latter remains fixated on beings. Believing a person to live in the fundamental openness of Being, Heidegger places such a person in the secondary world of “truth.” In order to overcome the remains of traditional philosophy in Heidegger’s ontology Richir turns to Merleau-Ponty’ “cosmology of the visible.” The author takes the Merleau-Ponty’s thesis that everything visible has something fundamentally invisible in it. This allows him to discover the universe of “nothing”, which includes both the visible and what is “behind” it. As a result Richir overcomes the classical dualism of the sensual and the intelligible. The concept of defenestration places the subject and the world in the same universe. (shrink)

This paper argues that there is a conflict between two theses held by John McDowell, namely i) the claim that we are under a standing obligation to revise our beliefs if reflection demands it; and ii) the view that veridical experience is a mode of direct access to the world. Since puts no bounds on what would constitute reasonable doubt, it invites skeptical concerns which overthrow. Conversely, since says that there are some experiences which we are entitled to trust, it (...) undermines the prescriptive scope of. Drawing on C. S. Peirce's distinction between genuine and contrived doubt, I maintain that critical revisions of beliefs should be triggered only by unwanted disruptions of habits, thereby restoring unity between McDowell's two theses.

What altered states of consciousness—the dissolution of feelings of time and self—can tell us about the mystery of consciousness. During extraordinary moments of consciousness—shock, meditative states and sudden mystical revelations, out-of-body experiences, or drug intoxication—our senses of time and self are altered; we may even feel time and self dissolving. These experiences have long been ignored by mainstream science, or considered crazy fantasies. Recent research, however, has located the neural underpinnings of these altered states of mind. In this book, neuropsychologist (...) Marc Wittmann shows how experiences that disturb or widen our everyday understanding of the self can help solve the mystery of consciousness. Wittmann explains that the relationship between consciousness of time and consciousness of self is close; in extreme circumstances, the experiences of space and self intensify and weaken together. He considers the emergence of the self in waking life and dreams; how our sense of time is distorted by extreme situations ranging from terror to mystical enlightenment; the experience of the moment; and the loss of time and self in such disorders as depression, schizophrenia, and epilepsy. Dostoyevsky reported godly bliss during epileptic seizures; neurologists are now investigating the phenomenon of the epileptic aura. Wittmann describes new studies of psychedelics that show how the brain builds consciousness of self and time, and discusses pilot programs that use hallucinogens to treat severe depression, anxiety, and addiction. If we want to understand our consciousness, our subjectivity, Wittmann argues, we must not be afraid to break new ground. Studying altered states of consciousness leads us directly to the heart of the matter: time and self, the foundations of consciousness. (shrink)
