Artificial intelligence, or AI, is a cross-disciplinary approach to understanding, modeling, and creating intelligence of various forms. It is a critical branch of cognitive science, and its influence is increasingly being felt in other areas, including the humanities. AI applications are transforming the way we interact with each other and with our environment, and work in artificially modeling intelligence is offering new insights into the human mind and revealing new forms mentality can take. This volume of original essays presents the state of the art in AI, surveying the foundations of the discipline, major theories of mental architecture, the principal areas of research, and extensions of AI such as artificial life. With a focus on theory rather than technical and applied issues, the volume will be valuable not only to people working in AI, but also to those in other disciplines wanting an authoritative and up-to-date introduction to the field.

It can be argued that dual-system theorists should adopt an action - based view of System 2 (S2), on which S2 reasoning is an intentional activity. It can also be argued that they should adopt a dual - attitude theory, on which the two systems have distinct sets of propositional attitudes. However, Peter Carruthers has argued that on the action-based view there are no S2 attitudes. This paper replies to Carruthers, proposing a view of S2 attitudes as virtual ones, which are partially realized in S1 attitudes. This view is compatible with, and a natural extension of, the action-based view.

Goff argues that Galileo erred in denying that sensory qualities are present in the physical world and that we should correct his error by supposing that all matter has an intrinsic conscious aspect. This paper argues that we should be open to another theoretical option. Galileo's real error, I argue, was not about the location of sensory qualities, but about their very existence. Like most people, Galileo assumed that sensory qualities are instantiated somewhere. I argue that this is a theoretical assumption which can and should be questioned. If we drop it, we can give a natural account of the function of sensory quality talk and explain how our puzzlement about consciousness arises.

Cognitive science is a cross-disciplinary enterprise devoted to understanding the nature of the mind. In recent years, investigators in philosophy, psychology, the neurosciences, artificial intelligence, and a host of other disciplines have come to appreciate how much they can learn from one another about the various dimensions of cognition. The result has been the emergence of one of the most exciting and fruitful areas of inter-disciplinary research in the history of science. This volume of original essays surveys foundational, theoretical, and philosophical issues across the discipline, and introduces the foundations of cognitive science, the principal areas of research, and the major research programs. With a focus on broad philosophical themes rather than detailed technical issues, the volume will be valuable not only to cognitive scientists and philosophers of cognitive science, but also to those in other disciplines looking for an authoritative and up-to-date introduction to the field

This book explores the idea that we have two minds - automatic, unconscious, and fast, the other controlled, conscious, and slow. In recent years there has been great interest in so-called dual-process theories of reasoning and rationality. According to such theories, there are two distinct systems underlying human reasoning - an evolutionarily old system that is associative, automatic, unconscious, parallel, and fast, and a more recent, distinctively human system that is rule-based, controlled, conscious, serial, and slow. Within the former, processes the former, processes are held to be innate and to use heuristics that evolved to solve specific adaptive problems. In the latter, processes are taken to be learned, flexible, and responsive to rational norms. Despite the attention these theories are attracting, there is still poor communication between dual-process theorists themselves, and the substantial bodies of work on dual processes in cognitive psychology and social psychology remain isolated from each other. This book brings together leading researchers on dual processes to summarize the state-of-the-art, highlight key issues, present different perspectives, explore implications, and provide a stimulus to further work. It includes new ideas about the human mind both by contemporary philosophers interested in broad theoretical questions about mental architecture and by psychologists specialising in traditionally distinct and isolated fields. For all those in the cognitive sciences, this is a book that will advance dual-process theorizing, promote interdisciplinary communication, and encourage further applications of dual-process approaches.

This book deals with the nature of consciousness. Many philosophers and psychologists today believe that the mind is a physical phenomenon, whose processes can be explained in scientific terms. Consciousness presents the biggest challenge to this view. Can the physical sciences really explain the nature of conscious experience—the way it feels to have a throbbing headache, or see a sunset, or smell freshly ground coffee? Or is there more to these experiences than a physical account can ever capture? If consciousness is non-physical, then it is hard to see how it can have effects within the physical world. But if it is physical, then why does it seem so different from other physical phenomena? And what physical processes does it involve? Is the feel of a conscious experience just a matter of what it represents? Does consciousness involve a form of inner awareness? Finally, could it be that our view of consciousness is mistaken? Do we need to rethink some of our fundamental assumptions about it? These questions go to the heart of our conception of ourselves and our place in the universe, and are the subject of vigorous debate among contemporary philosophers

According to dual-process theory, human cognition is supported by two distinct types of processing, one fast, automatic, and unconscious, the other slower, controlled, and conscious. These processes are sometimes said to constitute two minds – an intuitive old mind, which is evolutionarily ancient and composed of specialized subsystems, and a reflective new mind, which is distinctively human and the source of general intelligence. This theory has far-reaching consequences, and it means that research on enhancing and replicating human intelligence will need to take different paths, depending on whether it is the old mind or the new mind that is the target. This chapter examines these issues in depth. It argues first for a reinterpretation of dual-process theory, which pictures the new mind as a virtual system, formed by culturally transmitted habits of autostimulation. It then explores the implications of this reinterpreted dual-process theory for the projects of cognitive enhancement and artificial intelligence, including the creation of artificial general intelligence. The chapter concludes with a brief assessment of the risks of those projects as they appear in this new light.

Questions about the relation between mind and world have long occupied philosophers of mind. In _Consciousness in Action_ Susan Hurley invites us to adopt a ninety-degree shift and consider the relation between perception and action. The central theme of the book is an attack on what Hurley dubs the _Input-Output Picture_ of perception and actionthe picture of perceptions as sensory inputs to the cognitive system and intentions as motor outputs from it, with the mind occupying the buffer zone in between. Hurley argues that this picture confuses the personal level of normatively constrained mental contents and the subpersonal level of causal processes sustaining the mind. The notions of perception and action belong to the former, those of input and output to the latter. In place of the Input-Output picture, Hurley proposes a _Two-level _ _Interdependence View_. At the subpersonal level, she points out, there are not only one-way processes from input to output but also a host of feedback loops from output to inputsome internal to the central nervous system, some of wider orbit, involving proprioception, for example, or visual feedback on movement. The system as a whole can be seen as a _dynamical singularity_a tangle of sensorimotor feedback loops centred on the organism but extending out into the world beyond. The processes at this level are the vehicles of perceptions and actions, but, Hurley insists, the two levels cannot be mapped onto each other in a simple way. Changes on the output side may affect the content of perceptions, and changes on the input side may affect that of intentions. Perception and intention are in this way _interdependent_. The point here is not the uncontroversial one that perceptions and intentions can _cause_ changes in each other. That would be compatible with the Input-Output Picture. The dependency, in Hurleys view, is not instrumental, but _constitutive_: the contents of perceptions and intentions are each constituted by processes involving both inputs and outputs..
