<p style="margin-left:2.0%; margin-right:6%;font-size:0.95em;"><font face="Comic San MS, Trebuchet MS, Consolas">By thinking we usually mean such activities as calculating, cogitating, pondering, musing, reflecting, meditating, and ruminating. But we might also mean any of a broader range of actions or activities (or dispositions, states, processes, or whatever). I mean remembering, intending, imagining, conceiving, believing, desiring, hoping, feeling emotion, empathizing, following what someone is saying, minding, being conscious of something, and so on….I would like to include all the above as “thinking.” The general term most philosophers would use is mental phenomena....</font> <ref name=melser2004>Derek Melser.

Cognitive science is the interdisciplinary study of mind and intelligence, embracing philosophy, psychology, artificial intelligence, neuroscience, linguistics, anthropology, artificial intelligence, artificial life, and control engineering. Its intellectual origins are in the mid-1950s when researchers in several fields began to develop theories of mind based on complex representations and computational procedures. Its organizational origins are in the mid-1970s when the Cognitive Science Society was formed and the journal Cognitive Science began. Since then, more than sixty universities in North America, Europe, Asia, and Australia have established cognitive science programs, and many others have instituted courses in cognitive science.<ref> | Cognitive science is the interdisciplinary study of mind and intelligence, embracing philosophy, psychology, artificial intelligence, neuroscience, linguistics, anthropology, artificial intelligence, artificial life, and control engineering.

Questions like these have stood at the center of Western philosophy for centuries. In addressing them, philosophers have made certain fundamental assumptions—that we can know our own minds by introspection, that most of our thinking about the world is literal, and that reason is disembodied and universal—that are now called into question by well-established results of cognitive science. It has been shown empirically that: Most thought is unconscious. We have no direct conscious access to the mechanisms of thought and language. Our ideas go by too quickly and at too deep a level for us to observe them in any simple way. Abstract concepts are mostly metaphorical. Much of the subject matter of philosophy, such as the nature of time, morality, causation, the mind, and the self, relies heavily on basic metaphors derived from bodily experience. What is literal in our reasoning about such concepts is minimal and conceptually impoverished. All the richness comes from metaphor. For instance, we have two mutually incompatible metaphors for time, both of which represent it as movement through space: in one it is a flow past us and in the other a spatial dimension we move along. Mind is embodied. Thought requires a body—not in the trivial sense that you need a physical brain to think with, but in the profound sense that the very structure of our thoughts comes from the nature of the body. Nearly all of our unconscious metaphors are based on common bodily experiences. Most of the central themes of the Western philosophical tradition are called into question by these findings. The Cartesian person, with a mind wholly separate from the body, does not exist. The Kantian person, capable of moral action according to the dictates of a universal reason, does not exist. The phenomenological person, capable of knowing his or her mind entirely through introspection alone, does not exist. The utilitarian person, the Chomskian person, the poststructuralist person, the computational person, and the person defined by analytic philosophy all do not exist. Then what does? Lakoff and Johnson show that a philosophy responsible to the science of mind offers radically new and detailed understandings of what a person is. After first describing the philosophical stance that must follow from taking cognitive science seriously, they re-examine the basic concepts of the mind, time, causation, morality, and the self: then they rethink a host of philosophical traditions, from the classical Greeks through Kantian morality through modern analytic philosophy. They reveal the metaphorical structure underlying each mode of thought and show how the metaphysics of each theory flows from its metaphors. Finally, they take on two major issues of twentieth-century philosophy: how we conceive rationality, and how we conceive language. Philosophy in the Flesh reveals a radically new understanding of what it means to be human and calls for a thorough rethinking of the Western philosophical tradition. This is philosophy as it has never been seen before.</ref></p> | ||

Each discipline includes scholars interested in mental processes, or how the mind/brain works, or how the mind/brain/body works, or how the mind/brain/body/world works. Cognitive science centrally focuses on explaining exactly what we mean by mind, how we view it, what theories we have about it. | ||

*<b><u>Description:</u></b> This book presents a collection of linked essays written by one of the leading philosophers of biology, Kim Sterelny, on the topic of biological evolution. The first half of the book explores most of the main theoretical controversies about evolution and selection. Sterelny argues that genes are not the only replicators: non-genetic inheritance is also extremely important, and is no mere epiphenomenon of gene selection. The second half of the book applies some of these ideas in considering cognitive evolution. Concentrating on the mental capacities of simpler animals rather than those of humans, Sterelny argues for a general distinction between detection and representation, and that the evolution of belief, like that of representation, can be decoupled from the evolution of preference. These essays, some never before published, form a coherent whole that defends not just an overall conception of evolution, but also a distinctive take on cognitive evolution. | |||

===Mind as machine=== | ===Mind as machine=== | ||
Once we had the concept of machine, and built automata | Once we had acquired/generated the concept of machine, and built mechanical contrivances able to act as if by their own motive power ([[automata]]), we had the new concept, '<i>machine</i> as man', implementable as [[Robot|robots]], say — performing activities that humans can perform. As we built more and more elaborate and complicated automata — machines that could locomote, manipulate objects, compute, operate in response to logical rules, recognize speech — we began developing, increasingly refined, the analogous concept of '<i>man</i> as machine'. | ||
Elaborating the concept of '<i>man</i> as machine', modern biologists continually discover more details of the mechanisms, physiological and/or molecular, operating as components of the diverse activities performed by humans, including thinking and other activities of the mind. How could the ''mind'' of man exist except as an emergent manifestation of physiological/molecular processes. Injure the brain, alter the mind; injure/age the body, alter the mind. | |||
<i>Man</i> as machine' entails '<i>mind</i> as machine'. Man as a machine that can think and communicate with other machines like itself, and think about and communicate with itself. | |||
Humans do not just think, but emote, exhibit [[personality]], behave socially; recognize (re-cognize) themselves; recognize that they recognizes themselves — an autonomously functioning cognitive- and [[Metacognition|metacognitive-machine]], introspective, capable of constructing a detailed [[representation]] of aspects of the spatial and temporal reality embedding it, of that which it embeds, and capable of processing those representations as components of thinking and other mind-work. | |||

===The embodied mind=== | |||
"[Thomas] Aquinas held with Aristotle that ''nihil est in intellectu quod prius non fuerit in sensu'' (roughly, nothing is known to the mind that was not first known by the senses)..."<ref>[http://en.citizendium.org/wiki/Thomas_Aquinas Thomas Aquinas]</ref> | |||
The modern concept of the 'embodied mind' resonates with that ancient/medieval view, a concept of mind as emerging from and reflecting sensori-motor experiences, both conscious and unconscious but non-repressed. | |||
The peer-reviewed <I>Internet Encyclopedia of Philosophy</i> introduces the concept of embodied cognition emphasizing the following:<ref name=embodcog>[http://www.iep.utm.edu/embodcog/#H1 Embodied Cognition]. The Internet Encyclopedia of Philosophy: A Peer-Reviewed Academic Resource.</ref> | |||
*"The general theory contends that cognitive processes develop when a tightly coupled system emerges from real-time, goal-directed interactions between organisms and their environment;" | |||
*"the nature of these interactions influences the formation and further specifies the nature of the developing cognitive capacities." | |||
*"...one necessary condition for cognition is embodiment, where the basic notion of embodiment is broadly understood as the unique way an organism’s sensorimotor capacities enable it to successfully interact with its environmental niche." | |||
*"In addition, all of the different formulations of the general embodied cognition thesis share a common goal of developing cognitive explanations that capture the manner in which mind, body, and world mutually interact and influence one another to promote an organism’s adaptive success.” | |||
That formulation characterizes the mind as a complex dynamic adaptive emergent system; a system whereby cognitive functioning emerges from the interaction of the interrelated components, brain, body, and world; a system whereby the specifics of those interactions centered in the body influence the specifics of the cognitive functioning; a system whereby sensorimotor experiences, conscious and non-conscious, characterize the interactions among brain, body, and world as adaptations in real-time directed to respond to the mind-endowed organism's biological and cultural imperatives.<ref name=pfeifer2007>Pfeifer R, Bongard J, Grand S.

Then, using this account as a background, the essay considers the implications of these findings for an account of the functional integration of cognitive operations.

This change of methodology will motivate (even perhaps necessitate) the development of a new, domain-neutral vocabulary for characterizing the contribution of individual brain areas to larger functional complexes, and direct particular attention to the question of how these various area roles are integrated and coordinated to result in the observed cognitive effect. Finally, the details of the mix of cognitive functions a given area supports should tell us something interesting not just about the likely computational role of that area, but about the nature of and relations between the cognitive functions themselves.

In its broadest and most ambitious goal, the academic discipline of cognitive science aims to explain the physiological activities that we associate with the human living system and refer to as mind —
- thinking and feeling;
- perceiving
- speaking and other ways processing symbols;
- imagining;
- remembering;
- learning and knowing;
- experiencing events of reality consciously, non-consciously and unconsciously;
- reasoning and problem-solving;
- planning and decision-making;
- managing goals;
- dreaming;
- acting, behaving; and,
- a host of other mental activities.
Thinking
Philosopher Derek Melser gives a broader overview of the scope of 'thinking':
By thinking we usually mean such activities as calculating, cogitating, pondering, musing, reflecting, meditating, and ruminating. But we might also mean any of a broader range of actions or activities (or dispositions, states, processes, or whatever). I mean remembering, intending, imagining, conceiving, believing, desiring, hoping, feeling emotion, empathizing, following what someone is saying, minding, being conscious of something, and so on….I would like to include all the above as “thinking.” The general term most philosophers would use is mental phenomena.... [1]
Cognitive scientists ask: "How do people accomplish those differing kinds of thinking?"[2]
Scope and definitions of cognitive science
Margaret Boden, in her 2006 book, Mind as Machine: A History of Cognitive Science,[3] says this about defining cognitive science:
One of the founders of the field [cognitive science], when asked to define it, confessed that "Trying to speak for cognitive science, as if cognitive scientists had but one mind and one voice, is a bum's game" (G. A. Miller 1978: 6). And twenty years afterwards, two long-time leaders edited a book called What Is Cognitive Science? (Lepore and Pylyshyn 1999). You'd think they'd know by now! But no: even in the textbooks, never mind coffee conversations and idle chat, definitions differ.[3]
Nevertheless, we offer a few attempts:
The University of California, Berkeley offers an undergraduate degree-granting major in ‘Cognitive Science’, and explains the discipline as follows:
Cognitive Science is an interdisciplinary field that has arisen during the past decade at the intersection of a number of existing disciplines, including psychology, linguistics, computer science, philosophy, and physiology. The shared interest that has produced this coalition is understanding the nature of the mind. This quest is an old one, dating back to antiquity in the case of philosophy, but new ideas are emerging from the fresh approach of Cognitive Science. Previously, each discipline sought to understand the mind from its own perspective, benefiting little from progress in other fields because of different methods employed. With the advent of Cognitive Science, however, common interests and theoretical ideas have overcome methodological differences, and interdisciplinary interaction has become the hallmark of this field.[4] [5]
Notably, though the "….shared interest that has produced this coalition is understanding the nature of the mind", the complete webpage purporting to answer the question, “What is Cognitive Science?”, presumes comprehension of the word (or concept of) "mind".
William Bechtel and George Graham, in the introduction to their multi-authored text, A Companion to Cognitive Science,[6] define cognitive science as follows:
The expression 'cognitive science' names a broadly integrated class of approaches to the study of mental activities and processes, broad not just in the sense of including disciplines as varied as philosophy, cognitive psychology, linguistics, computer science, anthropology, and neuroscience, but in the sense that cognitive scientists tend to adopt certain basic, general assumptions about mind and intelligent thought and behavior. These include assumptions that the mind is (1) an information processing system, (2) a representational device, and (3) [in some sense] a computer. Various relations are possible among each of these assumptions; further, they are not shared by all who dub themselves cognitive scientists. Partly because of such relations and failures of uniformity, cognitive science has generated vigorous dialogues concerning the nature of mental activities and processes as well as over the nature of science and the structure of disciplines.[6]
Harvard University offers a webpage promoting a book by cognitive scientist, Phillip Johnson-LairdCite error: Invalid <ref>
tag; invalid names, e.g. too many that states:
The mind, he says, depends on the brain in the same way as the execution of a program of symbolic instructions depends on a computer, and can thus be understood by anyone willing to start with basic principles of computation and follow his step-by-step explanations.[7]
Margaret Boden’s 2006 book, Mind as Machine: A History of Cognitive Science,[3] views the mind as a machine, though a special one.
In my view, the best way to think about it [cognitive science] is as the study of mind as machine....however, more than one type of machine is relevant here. In a nutshell: some for digital computing, some for cybernetic self-organization or dynamical control. Much of the theoretical—and historical—interest in the field lies in the tension that follows from that fact.[3]
If a 'special' machine, perhaps because mind "emerged" from the interaction of molecular subsystems. Noam Chomsky has stated that "....the evolution of language may involve 'emergence' — the appearance of a qualitatively different phenomenon at a specific stage of complexity of organization."
If so, [Chomsky continues] it would be an interesting, but by no means novel, case of evolution. A similar view is widely held by evolutionary biologists and paleoanthropologists, for example, Ian Tattersall, who suggests more generally that human intelligence is an "emergent quality, the result of a chance combination of factors, rather than a product of Nature's patient and gradual engineering over the eons" [citation]. Still more generally, neuroscientist Vernon Mountcastle, introducing an American Academy of Arts and Sciences collection of essays on the state of the art at the conclusion of "the decade of the brain" that ended the last century, formulates the leading principle of these contributions as the thesis that "Things mental, indeed minds, are emergent properties of brains [my emphasis], . . . produced by principles . . . we do not yet understand" -- and that might derive from laws of nature [citation].[8]
The Stanford Encyclopedia of Philosophy offers these introductory words: Cognitive science is the interdisciplinary study of mind and intelligence, embracing philosophy, psychology, artificial intelligence, neuroscience, linguistics, anthropology, artificial intelligence, artificial life, and control engineering. Its intellectual origins are in the mid-1950s when researchers in several fields began to develop theories of mind based on complex representations and computational procedures. Its organizational origins are in the mid-1970s when the Cognitive Science Society was formed and the journal Cognitive Science began. Since then, more than sixty universities in North America, Europe, Asia, and Australia have established cognitive science programs, and many others have instituted courses in cognitive science.[9] |
Cognitive neuroscientists, George Lakoff and Mark Johnson, emphasize the role of the unconscious mind:
Cognitive science is the scientific discipline that studies conceptual systems. It is a relatively new discipline, having been founded in the 1970s. Yet in a short time it has made startling discoveries. It has discovered, first of all, that most of our thought is unconscious, not in the Freudian sense of being repressed, but in the sense that it operates beneath the level of cognitive awareness, inaccessible to consciousness and operating too quickly to be focused on.[10]
It seems that like many other sciences, cognitive science requires an interdisciplinary approach to try to explain the workings of what we commonly recognize as 'mind'. Each discipline includes scholars interested in mental processes, or how the mind/brain works, or how the mind/brain/body works, or how the mind/brain/body/world works. Cognitive science centrally focuses on explaining exactly what we mean by mind, how we view it, what theories we have about it.
Whatever theories we come up with, it seems that we come up with them with our minds. If minds operate as machines, then as living machines, to explain their workings we must take both a reductionist approach — looking at its parts — and a holistic approach — looking at it as a whole — and integrating the two approaches to yield a satisfying explanation that has explanatory and predictive power, and ultimately controlling power — self-controling power.
We begin, then, with an exploration of the concepts of mind that minds have proposed.
History of concepts of the mind
Areas of study by cognitive scientists
The interdisciplinary and multidisciplinary character of modern cognitive science reveals itself in even a greatly abbreviated list of definable 'areas of study' engaged in by cognitive scientists:[6]
The MIT Encyclopedia of the Cognitive Sciences (MITECS), edited by Robert A. Wilson and Frank C. Keil,[11] classifies the cognitive and brain sciences into six domains: (1) computational intelligence (2) culture, cognition, and evolution (3) linguistics and language (4) neuroscience (5) philosophy, and (6) psychology. The following list includes an illustrative selection of topics in those domains:
Theories of mindMind as machineOnce we had acquired/generated the concept of machine, and built mechanical contrivances able to act as if by their own motive power (automata), we had the new concept, 'machine as man', implementable as robots, say — performing activities that humans can perform. As we built more and more elaborate and complicated automata — machines that could locomote, manipulate objects, compute, operate in response to logical rules, recognize speech — we began developing, increasingly refined, the analogous concept of 'man as machine'. Elaborating the concept of 'man as machine', modern biologists continually discover more details of the mechanisms, physiological and/or molecular, operating as components of the diverse activities performed by humans, including thinking and other activities of the mind. How could the mind of man exist except as an emergent manifestation of physiological/molecular processes. Injure the brain, alter the mind; injure/age the body, alter the mind. Man as machine' entails 'mind as machine'. Man as a machine that can think and communicate with other machines like itself, and think about and communicate with itself. Humans do not just think, but emote, exhibit personality, behave socially; recognize (re-cognize) themselves; recognize that they recognizes themselves — an autonomously functioning cognitive- and metacognitive-machine, introspective, capable of constructing a detailed representation of aspects of the spatial and temporal reality embedding it, of that which it embeds, and capable of processing those representations as components of thinking and other mind-work. See also: Living systems as self-fabricating autonomous homeostatic cognitive machines. The embodied mind"[Thomas] Aquinas held with Aristotle that nihil est in intellectu quod prius non fuerit in sensu (roughly, nothing is known to the mind that was not first known by the senses)..."[16] The modern concept of the 'embodied mind' resonates with that ancient/medieval view, a concept of mind as emerging from and reflecting sensori-motor experiences, both conscious and unconscious but non-repressed. The peer-reviewed Internet Encyclopedia of Philosophy introduces the concept of embodied cognition emphasizing the following:[17]
That formulation characterizes the mind as a complex dynamic adaptive emergent system; a system whereby cognitive functioning emerges from the interaction of the interrelated components, brain, body, and world; a system whereby the specifics of those interactions centered in the body influence the specifics of the cognitive functioning; a system whereby sensorimotor experiences, conscious and non-conscious, characterize the interactions among brain, body, and world as adaptations in real-time directed to respond to the mind-endowed organism's biological and cultural imperatives.[18] The conscious mind as primary component of realitySome philosophers of mind believe the mind's ability to recognize itself requires a component of reality in addition to those recognized by physicists, specifically something called 'consciousness', fundamental as energy and matter.[19] The conscious mind, a physical machine, but only if physical reality includes 'consciousness' as a fundamental constituent of reality — perhaps a natural "organizing principle informing matter", call it 'soul'. Descartes came close to that notion, seeing the mind as immaterial and separate from the body, influencing the body through a strategy designed and owned by God. Mind as an evolutionary adaptation to Pleistocene lifestyleOthers explain cognition as adaptations to achieve fitness for survival, implemented by neurophyiological processes.[20] Mind as neurophysiological processingWe learn more and more about the neurophysiology of cognitive processes. We can detect cognitive and emotional adaptations occurring in real-time in the lifetime of individual organisms. The neurophysiology of conscious awareness remains undiscovered, however, explained by competing proposals. Mechanisms of cognition
Holding refs: [26] Applied cognitive science and engineeringOne of the lesser-known branches of psychology, cognitive psychology deals, significantly, with people not in distress, but trying to move to a higher level of functioning. The discipline deals with how people interact with new concepts in their environment, especially with respect to learning, or the mental processes involved in building skills. These topics are also the foundation on which human factors engineering, instructional technology, and user interface design are built. Much of the discipline deals with the conscious processes involved in learning, and in processing information that comes from existing and new sources. Bruning defined the cognitive movement as going beyond Skinner's stimulus-response, reflexive behaviorism into conscious learning.[27]
While Hofstetter describes a fundamental paradigm shift, experience in gaining certain skills may also draw from the behaviorists. "If faculty members can learn to shift their pedagogical paradigm from teacher-dominated to learner-centered, students will become more actively involved in the teaching and learning process. At the end of a course, instead of having been trained in the digestion of existing knowledge, students will have become able to continue finding, judging, critiquing, synthesizing, and constructing new knowledge... students will have become truly educated, not just trained." [27] Nevertheless, to take the quite different example of flying an advanced combat aircraft, developing the eye-hand coordination to merge the pilot's vision outside supplemented heads-up displays and pilot-selected "glass cockpit" displays, which are controlled from buttons and switches on controls operated without looking at them, can take a year increasingly of simulator and aircraft experience. While this may have behaviorist aspects, it is complemented by highly interactive classroom work on alternative tactics, emergency procedures, and the theory of one's aircraft and weapons. In contrast, cognitive psychologists involved in automobile safety suggest that adding heads-up displays to cars, without a very explicit training program, may cause information overload in the untrained driver. Information and decision flow in the OODA paradigmJohn Boyd, one of the pioneers of high-speed decisionmaking in the modern military, has a cognitive model at the core of his theories, the decision cycle or OODA Loop, the process by which an entity (either an individual or an organization) reacts to an event. According to this idea, the key to victory is to be able to create situations wherein one can make appropriate decisions more quickly than one's opponent. Boyd theorized that multilevel contexts, such as the tactical, operational, and strategic levels of war, can be modeled with a hierarchy of OODA loops (see below).[29] He also argued that fast OODA loops require a highly decentralized command and control using mission-type orders, or directive control (i.e., what the commander wants to see happen) as opposed to detailed control (i.e., how the commander wants things done. Such a structure, according to Boyd, would create a flexible "organic whole" that would be quicker to adapt to rapidly changing situations. He noted, however, that any such highly decentralized organization would necessitate a high degree of mutual trust and a common outlook that came from prior shared experiences. Headquarters needs to know that the troops are perfectly capable of forming a good plan for taking a specific objective, and the troops need to know that Headquarters does not direct them to achieve certain objectives without good reason. [29] The OODA model of decision and action, originally for air-to-air fighter combat, has four phases. This discussion adds interaction with intelligence and command.
After the action, the actor observes again, to see the effects of the action. If the cycle works properly, the actor has initiative, and can orient, decide, and act even faster in the second and subsequent iterations of the Boyd loop. Eventually, if the Boyd process works as intended, the actor will "get inside the opponent's loop". When the actor's Boyd cycle dominates the opponent's, the actor is acting repeatedly, based on reasoned choices, while the opponent is still trying to understand what is happening. Modes of learningIndividual human beings differ in the way they best learn new information. One common distinction uses:
There is an unfortunate trend, in areas such as industry-specific skills and certification training, to overemphasize the tactile, and insisting that as much learning as possible be "hands on". That may be realistic for computer configuration and troubleshooting, but design skills tend to be visual and collaborative, expressed through drawings, drafting documents, and discussion. Another unfortunate trend is to recognize that some people learn from all these methods, so, whether individual remote instruction or the classroom, multimedia presentation is important -- but, ideally, it should be possible to select the delivery mode. Auditory or visual input may be useless to people with disorders of the ears or eyes. Depending on the topic, however, the learner may need a theoretical base for what is presented in the multimedia experience, but, even there, the learning should be participatory. Lecturers who frequently turn to the class with questions and followup discussion, using their expertise to stay on track, encourage original thought. Such thought is reinforced with frequent individual and team exercises that require synthesis of concepts, often with multimedia or interpersonal interaction. Patterns of creating knowledgeSometimes called a trend to "big science", many fundamental research problems are sufficiently complex to need a team effort. In areas such as particle physics and space science, it will take a mixture of skills simply to conduct the experiments. Collaboration, however, may be a key part of learning and creating. As mentioned above, some classroom experiences deliberately include team exercises. A review of scientific publication showed the greatest growth in research by three authors [30] Cognitive trapsWithin the United States intelligence community and other areas where decisions must be made on incomplete knowledge, there is ever-growing awareness that cognitive errors come from poorly structured cognition and lack of collaboration.
