A theory that treats language not as an abstract symbol system but as a function of our brains and experience, integrating recent findings from biology, ...

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)

The now-classic Metaphors We Live By changed our understanding of metaphor and its role in language and the mind. Metaphor, the authors explain, is a fundamental mechanism of mind, one that allows us to use what we know about our physical and social experience to provide understanding of countless other subjects. Because such metaphors structure our most basic understandings of our experience, they are "metaphors we live by"--metaphors that can shape our perceptions and actions without our ever noticing them. In (...) this updated edition of Lakoff and Johnson's influential book, the authors supply an afterword surveying how their theory of metaphor has developed within the cognitive sciences to become central to the contemporary understanding of how we think and how we express our thoughts in language.

"There are books—few and far between—which carefully, delightfully, and genuinely turn your head inside out. This is one of them. It ranges over some central issues in Western philosophy and begins the long overdue job of giving us a radically new account of meaning, rationality, and objectivity."—Yaakov Garb, _San Francisco Chronicle_.

We explain here how the natural selection theory of people's mutualistic sense of fairness and the biofunctional theory of human understanding are made for each other. We welcome the stage that the target article has already set for this convergence, and invite the authors to consider moving the two independently developed approaches a step closer to the natural selection level of biofunctional understanding.

Damasio, an eminent neuroscientist explores the science of human emotion and what the great Dutch philosopher Baruch Spinoza can teach of how and why we feel. Damasio shows how joy and sorrow, those most defining of human feelings, are in fact the cornerstones of our survival and culture.

Reexamines the Western philosophical tradition, looking at the basic concepts of the mind, time, causation, morality, and the self.

Unlike the first English translation in 1974, this edition contains the text corresponding to Brentano's original 1874 edition.

In _The Meaning of the Body_, Mark Johnson continues his pioneering work on the exciting connections between cognitive science, language, and meaning first begun in the classic _Metaphors We Live By_. Johnson uses recent research into infant psychology to show how the body generates meaning even before self-consciousness has fully developed. From there he turns to cognitive neuroscience to further explore the bodily origins of meaning, thought, and language and examines the many dimensions of meaning—including images, qualities, emotions, and metaphors—that (...) are all rooted in the body’s physical encounters with the world. Drawing on the psychology of art and pragmatist philosophy, Johnson argues that all of these aspects of meaning-making are fundamentally aesthetic. He concludes that the arts are the culmination of human attempts to find meaning and that studying the aesthetic dimensions of our experience is crucial to unlocking meaning's bodily sources. Throughout, Johnson puts forth a bold new conception of the mind rooted in the understanding that philosophy will matter to nonphilosophers only if it is built on a visceral connection to the world. “Mark Johnson demonstrates that the aesthetic and emotional aspects of meaning are fundamental—central to conceptual meaning and reason, and that the arts show meaning-making in its fullest realization. If you were raised with the idea that art and emotion were external to ideas and reason, you must read this book. It grounds philosophy in our most visceral experience.”—George Lakoff, author of _Moral Politics_. (shrink)

Concepts are the elementary units of reason and linguistic meaning. They are conventional and relatively stable. As such, they must somehow be the result of neural activity in the brain. The questions are: Where? and How? A common philosophical position is that all concepts—even concepts about action and perception—are symbolic and abstract, and therefore must be implemented outside the brain’s sensory-motor system. We will argue against this position using (1) neuroscientific evidence; (2) results from neural computation; and (3) results about (...) the nature of concepts from cognitive linguistics. We will propose that the sensory-motor system has the right kind of structure to characterise both sensory-motor and more abstract concepts. Central to this picture are the neural theory of language and the theory of cogs, according to which, brain structures in the sensory-motor regions are exploited to characterise the so-called “abstract” concepts that constitute the meanings of grammatical constructions and general inference patterns.

The structure of everyday language implies that knowledge is an object. Like an object, it can be acquired, lost, stored, retrieved, and used. Anything that might be done to an external object could also be done to knowledge. Using concepts from the emerging field of biofunctional cognition, this paper discusses an alternative to the everyday-language framework of knowledge. The central idea is that the biological subsystems that comprise the physical nervous system have the capacity to create in us a live, (...) as opposed to pre-recorded, experience that might be described as intuitive self-awareness. In its various manifestations, this ongoing intuitive self-awareness is what we recognize as the knowledge inside us. There is no storage of knowledge of any kind. Intuitive self-awareness is in a perpetual state of re-creation and change. It serves as a private language with which the individual interacts directly with the subsystems of his/her own nervous system. This is the primary function of intuitive self-awareness &emdash; serving as the vehicle for the private communication between the individual and the individual's nervous system. Intuitive self-awareness has also come to serve, through evolutionary symbolic adaptation, as the foundation for the public language that the individual uses to communicate with other individuals. This is the secondary function of the intuitive self-awareness &emdash; to serve as the vehicle for public communication within social groups in which the individual lives. In this function, intuitive self-awareness externalizes to manifest itself in the form of an indirect code system for public communication. The nonsymbolic and symbolic forms of knowledge enable the organism to extend its internal world to encompass the external world in both its totality and detail. (shrink)
