According to the dominant computational approach in cognitive science, cognitive agents are digital computers; according to the alternative approach, they are dynamical systems. This target article attempts to articulate and support the dynamical hypothesis. The dynamical hypothesis has two major components: the nature hypothesis (cognitive agents are dynamical systems) and the knowledge hypothesis (cognitive agents can be understood dynamically). A wide range of objections to this hypothesis can be rebutted. The conclusion is that cognitive systems may well be dynamical systems, (...) and only sustained empirical research in cognitive science will determine the extent to which that is true. (shrink)

It is hardly a secret that with the philosophy of David Hume a conception of habit comes to occupy center-stage within epistemological and psychological reflection. Habit or custom is the "great guide of human life,"1 particularly in that it conditions, as the ground of the association of ideas, all our inductions concerning the objects of experience, and our beliefs that causal relations obtain between them. Yet according to Hume, we cannot say what habit itself is. Certainly, An Enquiry Concerning Human (...) Understanding describes a general and apparently common conception of "habit or custom"—terms which are presented as synonymous—in the following manner: "Wherever the repetition of any particular act or operation ..

How do minds emerge from developing brains? According to the representational features of cortex are built from the dynamic interaction between neural growth mechanisms and environmentally derived neural activity. Contrary to popular selectionist models that emphasize regressive mechanisms, the neurobiological evidence suggests that this growth is a progressive increase in the representational properties of cortex. The interaction between the environment and neural growth results in a flexible type of learning: minimizes the need for prespecification in accordance with recent neurobiological evidence (...) that the developing cerebral cortex is largely free of domain-specific structure. Instead, the representational properties of cortex are built by the nature of the problem domain confronting it. This uniquely powerful and general learning strategy undermines the central assumption of classical learnability theory, that the learning properties of a system can be deduced from a fixed computational architecture. Neural constructivism suggests that the evolutionary emergence of neocortex in mammals is a progression toward more flexible representational structures, in contrast to the popular view of cortical evolution as an increase in innate, specialized circuits. Human cortical postnatal development is also more extensive and protracted than generally supposed, suggesting that cortex has evolved so as to maximize the capacity of environmental structure to shape its structure and function through constructive learning.

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

The concept of habit enfolds an enormous richness and diversity of meanings. According to Husserl, habit, along with association, memory, and so on, belongs to the very essence of the psychic.1 Husserl even speaks of an overall genetic “phenomenology of habitualities”. In this paper, as an initial attempt to explicate the complexity of phenomenological treatments of habit, want to trace Husserl’s conception of habit as it emerged in his mature genetic phenomenology, in order to highlight his enormous and neglected original (...) contribution in this area. I shall show that Husserl was by no means limited to a Cartesian intellectualist explication of habitual action (as commentators such as Bourdieu and Dreyfus have claimed), but attempted to characterize its complexity across the range of human individual, sub-personal, personal, social and collective experience. Habit, as we shall see, for Husserl, is intimately involved in the constitution of meaningfulness (Husserl’s Sinnhaftigkeit) and forms of sense (Sinnesgestalten) at all levels, from the level of perceptual experience, through the formation of the ego, to the development of society, history and tradition, indeed to our whole sense of the harmonious course of worldly life and to the genetic constitution of worldhood as such. Habituality, furthermore, is a key structural principle in the genetic constitution of the transcendental ego itself, as it unfolds as a concrete living and acting person in an intersubjective, cultural and historical world.

I think, therefore I am. The legendary pronouncement of philosopher René Descartes lingers as accepted wisdom in the Western world nearly four centuries after its author's death. But does thought really come first? Who actually runs the show: we, our thoughts, or the neurons firing within our brains? Walter J. Freeman explores how we control our behavior and make sense of the world around us. Avoiding determinism both in sociobiology, which proposes that persons' genes control their brains' functioning, and in (...) neuroscience, which posits that their brains' disposition is molded by chemistry and environmental forces, Freeman charts a new course--one that gives individuals due credit and responsibility for their actions. Drawing upon his five decades of research in neuroscience, Freeman utilizes the latest advances in his field as well as perspectives from disciplines as diverse as mathematics, psychology, and philosophy to explicate how different human brains act in their chosen diverse ways. He clarifies the implications of brain imaging, by which neural activity can be observed during the course of normal movements, and shows how nonlinear dynamics reveals order within the fecund chaos of brain function.

For Aristotle, excellence is not an act but a habit, and Hume regards habit as ‘the great guide of life’. However, for Proust habit is problematic: ‘if habit is a second nature, it prevents us from knowing our first.’ What is habit? Do habits turn us into machines or free us to do more creative things? Should religious faith be habitual? Does habit help or hinder the practice of philosophy? Why do Luther, Spinoza, Kant, Kierkegaard and Bergson all criticise habit? (...) If habit is both a blessing and a curse, how can we live well in our habits? In this thought-provoking book Clare Carlisle examines habit from a philosophical standpoint. Beginning with a lucid appraisal of habit’s philosophical history she suggests that both receptivity and resistance to change are basic principles of habit-formation. Carlisle shows how the philosophy of habit not only anticipates the discoveries of recent neuroscience but illuminates their ethical significance. She asks whether habit is a reliable form of knowledge by examining the contrasting interpretations of habitual thinking offered by Spinoza and Hume. She then turns to the role of habit in the good life, tracing Aristotle’s legacy through the ideas of Joseph Butler, Hegel, and Félix Ravaisson, and assessing the ambivalent attitudes to habit expressed by Nietzsche and Proust. She argues that a distinction between habit and practice helps to clarify this ambivalence, particularly in the context of habit and religion, where she examines both the theology of habit and the repetitions of religious life. She concludes by considering how philosophy itself is a practice of learning to live well with habit. (shrink)

While philosophers of mind have been arguing over the status of mental representations in cognitive science, cognitive scientists have been quietly engaged in studying perception, action, and cognition without explaining them in terms of mental representation. In this book, Anthony Chemero describes this nonrepresentational approach, puts it in historical and conceptual context, and applies it to traditional problems in the philosophy of mind. Radical embodied cognitive science is a direct descendant of the American naturalist psychology of William James and John (...) Dewey, and follows them in viewing perception and cognition to be understandable only in terms of action in the environment. Chemero argues that cognition should be described in terms of agent-environment dynamics rather than in terms of computation and representation. After outlining this orientation to cognition, Chemero proposes a methodology: dynamical systems theory, which would explain things dynamically and without reference to representation. He also advances a background theory: Gibsonian ecological psychology, "shored up" and clarified. Chemero then looks at some traditional philosophical problems through the lens of radical embodied cognitive science and concludes that the comparative ease with which it resolves these problems, combined with its empirical promise, makes this approach to cognitive science a rewarding one. "Jerry Fodor is my favorite philosopher," Chemero writes in his preface, adding, "I think that Jerry Fodor is wrong about nearly everything." With this book, Chemero explains nonrepresentational, dynamical, ecological cognitive science as clearly and as rigorously as Jerry Fodor explained computational cognitive science in his classic work The Language of Thought.

Cognitive science is the project of understanding the mind by modelling its workings. Its development is one of the most remarkable and fascinating intellectual achievements of the modern era. Mind as Machine is a masterful history of cognitive science, told by one of its most eminent practitioners.

The Embodied Mind provides a unique, sophisticated treatment of the spontaneous and reflective dimension of human experience.

This book provides both a historical analysis of the philosophical problem of individuation, and a new trajectory in its treatment. Drawing on the work of Gilles Deleuze, as well as C.S. Peirce and the lesser-known Gilbert Simondon, Alberto Toscano takes the problem of individuation, as reconfigured by Kant and Nietzsche, into the realm of modernity, providing a unique and vibrant contribution to contemporary debates in European philosophy.
