The phenomenon of `consciousness' is intrinsically related to one's awareness of one's self, of time, and of the physical world. What, then, can be learned about consciousness from people who have suffered brain damage such as amnesia which affects their awareness? This is the question explored by Lawrence Weiskrantz, a distinguished neuropsychologist who has worked with such patients over 30 years. Written in an engaging and accessible style, Consciousness Lost and Found provides a unique perspective on one of (...) the most challenging issues in science today. (shrink)

In recent years consciousness has become a significant area of study in the cognitive sciences. The Frontiers of Consciousness is a major interdisciplinary exploration of consciousness. The book stems from the Chichele lectures held at All Souls College in Oxford, and features contributions from a 'who's who' of authorities from both philosophy and psychology. The result is a truly interdisciplinary volume, which tackles some of the biggest and most impenetrable problems in consciousness. The book includes chapters considering the apparent explanatory (...) gap between science and consciousness, our conscious experience of emotions such as fear, and of willed actions by ourselves and others. It looks at subjective differences between two ways in which visual information guides behaviour, and scientific investigation of consciousness in non-human animals. It looks at the challenges that the mind-brain relation presents for clinical practice as well as for theories of consciousness. The book draws on leading research from philosophy, experimental psychology, functional imaging of the brain, neuropsychology, neuroscience, and clinical neurology. Distinctive in its accessibility, authority, and its depth of coverage, Frontiers of Consciousness will be a groundbreaking and influential addition to the consciousness literature. (shrink)

The first edition of Blindsight, written by Lawrence Weiskrantz was an important and highly cited account of studies of the phenomenon - Blindsight. The updated edition retains the original text of the first edition, but brings the book up to date with developments in this area in the past decade.

Listening to subject’s commentaries can be a useful spur to novel scientific departures, as in studies of blindsight. Recently further testing has been possible with subject DB, who was a blindsight patient tested intensively over a period of 10 years and who was the subject of the book, . Essentially his original capacity is the same or somewhat more sensitive. Some further types of discriminations have now been tested that were not possible in the original study. But a new feature (...) was discovered, namely that he describes conscious after-images of a wide range of inducing stimuli of which he is unconscious. The properties of the after-images are briefly described, such as their occurrence following unseen colour patches, luminance changes, shape, spatial frequency, their long durations, showing inter-ocular transfer, as well as their conforming to Emmert’s Law. Various approaches are discussed towards finding the source of their generation, such as the use of after-images of colour mixes of separate inputs to the two eyes . They are also discussed in terms of after-images in normal subjects that are generated by imagination. The discovery offers a rare potential opportunity to compare the brain activity associated with both the conscious and unconscious attributes of the precisely the same stimuli in the same locus in the same subject.

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statis- tics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement record- ing systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During perceptual experience, association areas in the (...) brain capture bottom-up patterns of activation in sensory-motor areas. Later, in a top-down manner, association areas partially reactivate sensory-motor areas to implement perceptual symbols. The stor- age and reactivation of perceptual symbols operates at the level of perceptual components – not at the level of holistic perceptual expe- riences. Through the use of selective attention, schematic representations of perceptual components are extracted from experience and stored in memory (e.g., individual memories of green, purr, hot). As memories of the same component become organized around a com- mon frame, they implement a simulator that produces limitless simulations of the component (e.g., simulations of purr). Not only do such simulators develop for aspects of sensory experience, they also develop for aspects of proprioception (e.g., lift, run) and introspec- tion (e.g., compare, memory, happy, hungry). Once established, these simulators implement a basic conceptual system that represents types, supports categorization, and produces categorical inferences. These simulators further support productivity, propositions, and ab- stract concepts, thereby implementing a fully functional conceptual system. Productivity results from integrating simulators combinato- rially and recursively to produce complex simulations. Propositions result from binding simulators to perceived individuals to represent type-token relations. Abstract concepts are grounded in complex simulations of combined physical and introspective events. Thus, a per- ceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal sym- bol systems. Implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored. (shrink)

In this paper we look at the manual analysis of arguments and how this compares to the current state of automatic argument analysis. These considerations are used to develop a new approach combining a machine learning algorithm to extract propositions from text, with a topic model to determine argument structure. The results of this method are compared to a manual analysis.

Indispensable and multidisciplinary resource in philosophy, literature, cultural studies, social theory, and religious studies.

Jnanasrimitra (975-1025) was regarded by both Buddhists and non-Buddhists as the most important Indian philosopher of his generation. His theory of exclusion combined a philosophy of language with a theory of conceptual content to explore the nature of words and thought. Jnanasrimitra's theory informed much of the work accomplished at Vikramasila, a monastic and educational complex instrumental to the growth of Buddhism. His ideas were also passionately debated among successive Hindu and Jain philosophers. This volume marks the first English translation (...) of Jnanasrimitra's Monograph on Exclusion, a careful, critical investigation into language, perception, and conceptual awareness. Featuring the rival arguments of Buddhist and Hindu intellectuals, among other thinkers, the Monograph reflects more than half a millennium of competing claims while providing an invaluable introduction to a crucial philosopher. Lawrence J. McCrea and Parimal G. Patil familiarize the reader with the author, themes, and topics of the text and situate Jnanasrimitra's findings within his larger intellectual milieu. Their clear, accessible, and accurate translation proves the influence of Jnanasrimitra on the foundations of Buddhist and Indian philosophy. (shrink)

Many kinds of relativism have been attributed to Karl Marx. We discuss three broad areas of Marx’s thinking: his theories of history, science, and morality. Along the way, we show that Marx is committed to a version of philosophical naturalism that privileges the results of genuine science over alternative ways of understanding the world. This outlook presupposes the possibility of objective knowledge of the world. It follows that Marx is no relativist (at least in the senses we consider). Unlike many (...) non-relativists, however, Marx pays close attention to the problems with which contemporary philosophers interested in relativism are most preoccupied: irresolvable moral disagreements between social groups, the evolution of institutions and practices over time, and the prominent, perhaps decisive role played by non-cognitive social factors in belief formation. We show how some later Marxists have mistaken this close attention for evidence that Marx himself is a relativist. (shrink)
