Figments Of Reality
''Figments of Reality: The Evolution of the Curious Mind'' (1997) is a book about the evolution of the intelligent and conscious human mind by biologist Jack Cohen and mathematician Ian Stewart. Overview In this book Cohen and Stewart give their ideas on how the sentient human being evolved. Various chapters discuss scientific and philosophical ideas such as emergence and chaos, free will, perception versus reality, objectivity versus subjectivity, self-awareness, the ego and id, groupthink, and extelligence. A theme is that the traditional reductionist approach of trying to understand things as interaction of simpler things can not alone explain such complex concepts as intelligence or culture. To better understand them one has to consider also the context in which they have evolved and the fact that the evolution is a recursive process, often changing the context so that previously unseen evolutionary paths became available. The authors claim that intelligence is an inevit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jack Cohen (scientist)
Jack Cohen, FRSB (19 September 1933 – 6 May 2019) was a British reproductive biologist also known for his science books and involvement with science fiction. Life Cohen was born 19 September 1933 in Norwich, but grew up in Stoke Newington.''The Jewish Chronicle'' 6 July 2005 "Not only connections" His father was killed shortly after the end of the Second World War, 1 September 1945. His grandfather was a rabbi and Cohen was an observant Jew in his youth. He continued to attend the synagogue for cultural reasons. He was married three times, and had six children. Academic career Cohen studied at University College, Hull, where he obtained a BSc (external degree of the University of London) in 1954. He obtained his PhD in Zoology at the same institution (by then Hull University) in 1957.

Groupthink
Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Cohesiveness, or the desire for cohesiveness, in a group may produce a tendency among its members to agree at all costs. This causes the group to minimize conflict and reach a consensus decision without critical evaluation. Groupthink is a construct of social psychology, but has an extensive reach and influences literature in the fields of communication studies, political science, management, and organizational theory, as well as important aspects of deviant religious cult behaviour. Overview Groupthink is sometimes stated to occur (more broadly) within natural groups within the community, for example to explain the lifelong different mindsets of those with differing political views (such as "conservatism" and "liberalism" in the U.S. political context or the purported benefits ...

Evolutionary Biology Literature
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biology Books
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Books By Ian Stewart (mathematician)
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is '' codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reductionist
Reductionism is any of several related philosophical ideas regarding the associations between phenomena which can be described in terms of other simpler or more fundamental phenomena. It is also described as an intellectual and philosophical position that interprets a complex system as the sum of its parts. Definitions ''The Oxford Companion to Philosophy'' suggests that reductionism is "one of the most used and abused terms in the philosophical lexicon" and suggests a three-part division: # Ontological reductionism: a belief that the whole of reality consists of a minimal number of parts. # Methodological reductionism: the scientific attempt to provide an explanation in terms of ever-smaller entities. # Theory reductionism: the suggestion that a newer theory does not replace or absorb an older one, but reduces it to more basic terms. Theory reduction itself is divisible into three parts: translation, derivation, and explanation. Reductionism can be applied to any phenomenon, ...

Extelligence
Extelligence is a term coined by Ian Stewart and Jack Cohen in their 1997 book ''Figments of Reality''. They define it as the cultural capital that is available to us in the form of external media (e.g. tribal legends, folklore, nursery rhymes, books, videotapes, CD-ROMs, etc.) They contrast extelligence with intelligence, or the knowledge and cognitive processes within the brain. Furthermore, they regard the 'complicity' of extelligence and intelligence as fundamental to the development of consciousness in evolutionary terms for both the species and the individual. 'Complicity' is a combination of complexity and simplicity, and Cohen and Stewart use it to express the interdependent relationship between knowledge-inside-one's-head and knowledge-outside-one's-head that can be readily accessed. Although Cohen's and Stewart's respective disciplines are biology and mathematics, their description of the complicity of intelligence and extelligence is in the tradition of Jean Piaget, Be ...

Id, Ego And Super-ego
The id, ego, and super-ego are a set of three concepts in psychoanalytic theory describing distinct, interacting agents in the psychic apparatus (defined in Sigmund Freud's structural model of the psyche). The three agents are theoretical constructs that describe the activities and interactions of the mental life of a person. In the ego psychology model of the psyche, the id is the set of uncoordinated instinctual desires; the super-ego plays the critical and moralizing role; and the ego is the organized, realistic agent that mediates between the instinctual desires of the id and the critical super-ego; Freud explained that: The functional importance of the ego is manifested in the fact that, normally, control over the approaches to motility devolves upon it. Thus, in its relation to the id, he egois like a man on horseback, who has to hold in check the superior strength of the horse; with this difference, that the rider tries to do so with his own strength, while the ego uses b ...

Ian Stewart (mathematician)
Ian Nicholas Stewart (born 24 September 1945) is a British mathematician and a popular-science and science-fiction writer. He is Emeritus Professor of Mathematics at the University of Warwick, England. Education and early life Stewart was born in 1945 in Folkestone, England. While in the sixth form at Harvey Grammar School in Folkestone he came to the attention of the mathematics teacher. The teacher had Stewart sit mock A-level examinations without any preparation along with the upper-sixth students; Stewart was placed first in the examination. He was awarded a scholarship to study at the University of Cambridge as an undergraduate student of Churchill College, Cambridge, where he studied the Mathematical Tripos and obtained a first-class Bachelor of Arts degree in mathematics in 1966. Stewart then went to the University of Warwick where his PhD on Lie algebras was supervised by Brian Hartley and completed in 1969. Career and research After his PhD, Stewart was offered an a ...

Self-awareness
In philosophy of self, self-awareness is the experience of one's own personality or individuality. It is not to be confused with consciousness in the sense of qualia. While consciousness is being aware of one's environment and body and lifestyle, self-awareness is the recognition of that awareness. Self-awareness is how an individual consciously knows and understands their own character, feelings, motives, and desires. Neurobiological basis Introduction There are questions regarding what part of the brain allows us to be self-aware and how we are biologically programmed to be self-aware. V.S. Ramachandran has speculated that mirror neurons may provide the neurological basis of human self-awareness. In an essay written for the Edge Foundation in 2009, Ramachandran gave the following explanation of his theory: "... I also speculated that these neurons can not only help simulate other people's behavior but can be turned 'inward'—as it were—to create second-order representa ...
