An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.

The term ‘emergence’ often causes confusion in science and philosophy, as it is used to express at least two quite different concepts. We can label these concepts _strong_ _emergence_ and _weak emergence_. Both of these concepts are important, but it is vital to keep them separate.

Physicalism is the thesis that everything is physical, or as contemporary philosophers sometimes put it, that everything supervenes on, or is necessitated by, the physical. The thesis is usually intended as a metaphysical thesis, parallel to the thesis attributed to the ancient Greek philosopher Thales, that everything is water, or the idealism of the 18th Century philosopher Berkeley, that everything is mental. The general idea is that the nature of the actual world (i.e. the universe and everything in it) conforms (...) to a certain condition, the condition of being physical. Of course, physicalists don't deny that the world might contain many items that at first glance don't seem physical — items of a biological, or psychological, or moral, or social nature. But they insist nevertheless that at the end of the day such items are either physical or supervene on the physical. (shrink)

This paper responds to the issues raised by D. Chalmers by offering a research direction which is quite radical because of the way in which methodological principles are linked to scientific studies of consciousness. Neuro-phenomenology is the name I use here to designate a quest to marry modern cognitive science and a disciplined approach to human experience, thereby placing myself in the lineage of the continental tradition of Phenomenology. My claim is that the so-called hard problem that animates these Special (...) Issues can only be addressed productively by gathering a research community armed with new pragmatic tools for the development of a science of consciousness. I will claim that no piecemeal empirical correlates, nor purely theoretical principles, will really help us at this stage. We need to turn to a systematic exploration of the only link between mind and consciousness that seems both obvious and natural: the structure of human experience itself. In what follows I motivate my choice by briefly examining the current debate about consciousness at the light of Chalmer’s hard problem. Next, I outline the phenomenological strategy. Finally I conclude by discussing some of the main difficulties and consequences of this strategy. (shrink)

There are few more unsettling philosophical questions than this: What happens in attempts to reduce some properties to some other more fundamental properties?

In light of the central role scientific research plays in Merleau-Ponty’s phenomenology, the question has arisen whether his phenomenology involves some sort of commitment to naturalism or whether it is better understood along transcendental lines. In order to make headway on this issue, I focus specifically on Merleau-Ponty’s method and its relationship to Kant’s transcendental method. On the one hand, I argue that Merleau-Ponty rejects Kant’s method, the ‘method-without-which’, which seeks the a priori conditions of the possibility of experience. On (...) the other hand, I show that this does not amount to a methodological rejection of the transcendental altogether. To the contrary, I claim that Merleau-Ponty offers a new account of the transcendental and a priori that he takes to be the proper subject matter of his phenomenological method, the method of ‘radical reflection’. And I submit that this method has important affinities with aesthetic themes in Kant’s philosophy. (shrink)

Enactivist Interventions is an interdisciplinary work that explores how theories of embodied cognition illuminate many aspects of the mind, including perception, affect, and action. Gallagher argues that the brain is not secluded from the world or isolated in its own processes, but rather is dynamically connected with body and environment.

Whether or not Merleau-Ponty’s version of phenomenology should be considered a form of ‘transcendental’ philosophy is open to debate. Although the Phenomenology of Perception presents his position as a transcendental one, many of its features—such as its exploitation of empirical science—might lead to doubt that it can be. This paper considers whether Merleau-Ponty meets what I call the ‘transcendentalist challenge’ of defining and grounding claims of a distinctive transcendental kind. It begins by highlighting three features—the absolute ego, the pure phenomenal (...) field, and the reduction—that Husserl had used to justify claims of a specifically transcendental kind within a phenomenological framework. It then examines how Merleau-Ponty modifies each of these features to focus on the lived body and a factically conditioned phenomenal field, while remaining ambivalent about the reduction. Finally, it assesses whether Merleau-Ponty’s modified position can still legitimately be considered transcendental. I argue that—despite his own rhetoric—this modified position shapes the modality of Merleau-Ponty’s claims in such a way that his phenomenology cannot meet the transcendentalist challenge and therefore should not be considered ‘transcendental.’.

Where does the mind begin and end? Most philosophers and cognitive scientists take the view that the mind is bounded by the skull or skin of the individual. Robert Wilson, in this provocative and challenging 2004 book, provides the foundations for the view that the mind extends beyond the boundary of the individual. The approach adopted offers a unique blend of traditional philosophical analysis, cognitive science, and the history of psychology and the human sciences. The companion volume, Genes and the (...) Agents of Life, explores the theme in the biological sciences. Written with verve and clarity, this ambitious book will appeal to a broad swathe of professionals and students in philosophy, psychology, cognitive science, and the history of the behavioural and human sciences.

Science and its philosophical companion, Naturalism, represent reality in wholly nonpersonal terms. How, if at all, can a nonpersonal scheme accommodate the first-person perspective that we all enjoy? In this volume, Lynne Rudder Baker explores that question by considering both reductive and eliminative approaches to the first-person perspective. After finding both approaches wanting, she mounts an original constructive argument to show that a non-Cartesian first-person perspective belongs in the basic inventory of what exists. That is, the world that contains us (...) persons is irreducibly personal.After arguing for the irreducibilty and ineliminability of the first-person perspective, Baker develops a theory of this perspective. The first-person perspective has two stages, rudimentary and robust. Human infants and nonhuman animals with consciousness and intentionality have rudimentary first-person perspectives. In learning a language, a person acquires a robust first-person perspective: the capacity to conceive of oneself as oneself, in the first person. By developing an account of personal identity, Baker argues that her theory is coherent, and she shows various ways in which first-person perspectives contribute to reality. (shrink)

First published in 1945, Maurice Merleau-Ponty’s monumental _Phénoménologie de la perception _signalled the arrival of a major new philosophical and intellectual voice in post-war Europe. Breaking with the prevailing picture of existentialism and phenomenology at the time, it has become one of the landmark works of twentieth-century thought. This new translation, the first for over fifty years, makes this classic work of philosophy available to a new generation of readers. _Phenomenology of Perception _stands in the great phenomenological tradition of Husserl, (...) Heidegger, and Sartre. Yet Merleau-Ponty’s contribution is decisive, as he brings this tradition and other philosophical predecessors, particularly Descartes and Kant, to confront a neglected dimension of our experience: the lived body and the phenomenal world. Charting a bold course between the reductionism of science on the one hand and "intellectualism" on the other, Merleau-Ponty argues that we should regard the body not as a mere biological or physical unit, but as the body which structures one’s situation and experience within the world. Merleau-Ponty enriches his classic work with engaging studies of famous cases in the history of psychology and neurology as well as phenomena that continue to draw our attention, such as phantom limb syndrome, synaesthesia, and hallucination. This new translation includes many helpful features such as the reintroduction of Merleau-Ponty’s discursive Table of Contents as subtitles into the body of the text, a comprehensive Translator’s Introduction to its main themes, essential notes explaining key terms of translation, an extensive Index, and an important updating of Merleau-Ponty’s references to now available English translations. Also included is a new foreword by Taylor Carman and an introduction to Merleau-Ponty_ _by Claude Lefort. Translated by Donald A. Landes. (shrink)

Normativity concerns what we ought to think or do and the evaluations we make. For example, we say that we ought to think consistently, we ought to keep our promises, or that Mozart is a better composer than Salieri. Yet what philosophical moral can we draw from the apparent absence of normativity in the scientific image of the world? For scientific naturalists, the moral is that the normative must be reduced to the nonnormative, while for nonnaturalists, the moral is that (...) there must be a transcendent realm of norms. _Naturalism and Normativity_ engages with both sides of this debate. Essays explore philosophical options for understanding normativity in the space between scientific naturalism and Platonic supernaturalism. They articulate a liberal conception of philosophy that is neither reducible to the sciences nor completely independent of them—yet one that maintains the right to call itself naturalism. Contributors think in new ways about the relations among the scientific worldview, our experience of norms and values, and our movements in the space of reason. Detailed discussions include the relationship between philosophy and science, physicalism and ontological pluralism, the realm of the ordinary, objectivity and subjectivity, truth and justification, and the liberal naturalisms of Donald Davidson, John Dewey, John McDowell, and Ludwig Wittgenstein.

A new theory is taking hold in neuroscience. It is the theory that the brain is essentially a hypothesis-testing mechanism, one that attempts to minimise the error of its predictions about the sensory input it receives from the world. It is an attractive theory because powerful theoretical arguments support it, and yet it is at heart stunningly simple. Jakob Hohwy explains and explores this theory from the perspective of cognitive science and philosophy. The key argument throughout The Predictive Mind is (...) that the mechanism explains the rich, deep, and multifaceted character of our conscious perception. It also gives a unified account of how perception is sculpted by attention, and how it depends on action. The mind is revealed as having a fragile and indirect relation to the world. Though we are deeply in tune with the world we are also strangely distanced from it. (shrink)

In _Phenomenology, Naturalism and Empirical Science_, Jack Reynolds takes the controversial position that phenomenology and naturalism are compatible, and develops a hybrid account of phenomenology and empirical science. Though phenomenology and naturalism are typically understood as philosophically opposed to one another, Reynolds argues that this resistance is based on an understanding of transcendental phenomenology that is ultimately untenable and in need of updating. Phenomenology, as Reynolds reorients it, is compatible with liberal naturalism, as well as with weak forms of methodological (...) naturalism. Chapters explore areas where scientific and phenomenological work overlap and sometimes conflict, contesting standard ways of understanding the relationship between phenomenological philosophy and empirical science. The book outlines the significance of the first-person perspective characteristic of phenomenology—both epistemically and ontologically—while according due respect to the relevant empirical sciences. This book makes a significant contribution to one of the central issues in phenomenology and argues for phenomenology’s ongoing importance for the future of philosophy. (shrink)

Jaegwon Kim has argued (Kim 2006a) that the two key issues for emergentism are to give a positive characterization of the emergence relation and to explain the possibility of downward causation. This paper proposes an account of emergence which provides new answers to these two key issues. It is argued that an appropriate emergence relation is characterized by a notion of ‘transformation’, and that the real key issue for emergentism is located elsewhere than the places Kim identifies. The paper builds (...) on Victor Caston’s important work on ancient philosophy of mind (Caston 1997, 2001), but appeals to sources he has not considered. (shrink)

Philosophical accounts of emergence have been explicated in terms of logical relationships between statements (derivation) or static properties (function and realization). Jaegwon Kim is a modern proponent. A property is emergent if it is not explainable by (or reducible to) the properties of lower level components. This approach, I will argue, is unable to make sense of the kinds of emergence that are widespread in scientific explanations of complex systems. The standard philosophical notion of emergence posits the wrong dichotomies, confuses (...) compositional physicalism with explanatory physicalism, and is unable to represent the type of dynamic processes (self-organizing feedback) that both generate emergent properties and express downward causation.

The terminological boxes into which we press the history of philosophy often obscure deep and important differences among major figures supposedly belonging to a single school of thought. One such disparity within the phenomenological movement, often overlooked but by no means invisible, separates Merleau-Pontys Phenomenology of Perception from the Husserlian program that initially inspired it. For Merleau-Pontys phenomenology amounts to a radical, if discreet, departure not only from Husserls theory of intentionality generally, but more specifically from his account of the (...) intentional constitution of the body and its role in perceptual experience.

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)

Collected in this text are the written notes of courses on the concept of nature give by Merleau-Ponty at the College de France in the 1950s. The ideas that animated the philosopher's lectures emerge in an early, fluid form in the process of being elaborated, negotiated, critiqued and reconsidered.

A traditional view of perception and action makestwo assumptions: that the causal flow betweenperception and action is primarily linear or one-way,and that they are merely instrumentally related toeach other, so that each is a means to the other.Either or both of these assumptions can be rejected. Behaviorism rejects the instrumental but not theone-way aspect of the traditional view, thus leavingitself open to charges of verificationism. Ecologicalviews reject the one-way aspect but not theinstrumental aspect of the traditional view, so thatperception and (...) action are seen as instrumentallyinterdependent. It is argued here that a betteralternative is to reject both assumptions, resultingin a two-level interdependence view in whichperception and action co-depend on dynamicallycircular subpersonal relations and as a result may bemore than merely instrumentally interdependent. Thisis illustrated by reference to motor theories ofperception and control theories of action. (shrink)

Emergence develops a novel account of diachronic ontological emergence called transformational emergence and locates it in an established historical framework. The author shows how many problems affecting ontological emergence result from a dominant but inappropriate metaphysical tradition and provides a comprehensive assessment of current theories of emergence.

The paper links discussions of two topics: biological individuality and the simplest forms of mentality. I discuss several attempts to locate the boundary between metabolic activity and ‘minimal cognition.’ I then look at differences between the kinds of individuality present in unicellular life, multicellular life in general, and animals of several kinds. Nervous systems, which are clearly relevant to cognition and subjectivity, also play an important role in the form of individuality seen in animals. The last part of the paper (...) links these biological transitions to the evolutionary history of subjective experience. (shrink)

Theories of embodied cognition abound in the literature, but it is often unclear how to understand them. We offer several interpretations of embodiment, the most interesting being the thesis that mental representations in bodily formats (B-formats) have an important role in cognition. Potential B-formats include motoric, somatosensory, affective and interoceptive formats. The literature on mirroring and related phenomena provides support for a limited-scope version of embodied social cognition under the B-format interpretation. It is questionable, however, whether such a thesis can (...) be extended. We show the limits of embodiment in social cognition. (shrink)

Resistance to the idea that phenomenology can be relevant to cognitive scientific explanation has faced two objections advanced, respectively, from both sides of the issue: from the scientific perspective it has been suggested that phenomenology, understood as an account of first-person experience, is ultimately reducible to cognitive neuroscientific explanation; and from a phenomenological perspective it has been argued that phenomenology cannot be naturalized. In this context it makes sense to consider that the notion of scientific reduction is linked to a (...) classic scientific conception of nature. I argue that if properly understood, the proposal to rethink the concept of nature itself, in enactivist phenomenological approaches, undermines the reductionist program and redefines what it means for phenomenology to be naturalized.

Most philosophical accounts of emergence are based on supervenience, with supervenience being an ontologically synchronic relation of determination. This conception of emergence as a relation of supervenience, I will argue, is unable to make sense of the kinds of emergence that are widespread in self-organizing and nonlinear dynamical systems, including distributed cognitive systems. In these dynamical systems, an emergent property is ontological and diachronic.

The concept of emergence appears in various places within the literature on expertise and expert practice. Here, I examine some of these applications of emergence in the light of two prominent accounts of emergence from the philosophy of science and philosophy of mind. I evaluate these accounts with respect to several specific contexts in which emergence seems to be an appropriate way of characterizing expertise in groups. While it is sometimes assumed that emergent phenomena are in some way inexplicable, the (...) two accounts of emergence I discuss highlight ways in which the concept of emergence relates to specific styles of explanation.
