A History of Bodies, Brains, and Minds
"A brief history of life and of the emergence of our species, focusing on the biological evolution of brains and conscious behavior and ending with some speculations about our future"--
A History of Bodies, Brains, and Minds
A panoramic view of the evolution of life on our planet, from its origins to humanity’s future. In A History of Bodies, Brains, and Minds, Francisco Aboitiz provides a brief history of life, the brain, and cognition, from the earliest living beings to our own species. The author proceeds from the basic premise that, since evolution by natural selection is the process underlying the origin of life and its evolution on earth, the brain—and thus our minds—must also be the result of biological evolution. The aim of this book is to narrate how animal bodies came to be built with their nervous systems and how our species evolved with culture, technology, language, and consciousness. The book is organized in four parts, each delving into a different aspect of evolutionary development: • Definitions lays the groundwork by discussing the principles of biological evolution and explores the definition and mechanisms of life itself. • Beginnings describes the origins of life, starting from the emergence of the first cells to the development of neurons as the building blocks for brain networks. • The Rise of Bodies and Brains examines the evolution of animals with bilateral symmetry, the emergence of chordates and vertebrates, and the expansion and diversification of the vertebrate brain. • A Singular Ape explores Homo sapiens and our species’ unique traits, such as bipedality, tool use, culture, language, communication, and consciousness. Comprehensive and deeply insightful, this book helps us understand our place in the natural world and the cosmos—as well as what the future might hold for life on earth.
Brain, Mind and the Signifying Body
"Brain, Mind and the Signifying Body" is an exploration of a multimodal theory of cognitive science. Using linguistic theories first developed by Saussure and more latterly by M. A. K. Halliday, Paul Thibault analyses how social and biological systems interact to produce meaning. This fascinating study will be of interest to undergraduates and academics researching cognitive linguistics and advanced semiotics. The book engages with the current dialogue between the human and life sciences to ask questions about the relationship between the physical, biological aspects of a human being, and the sociocultural framework in which a human being exists. Paul J. Thibault argues that we need to understand both the semiotic, discursive nature of meaning making, and the physical context in which this activity takes place. The two are inseparable, and hence the only way we can understand our subjective experience of our environment and our perceptions of our inner states of mind is by giving equal weight to both frameworks. This 'ecosocial semiotic' theory engages with linguistics, semiotics, activity theory, biology and psychology. In so doing, the book produces a new way of looking at how a human being makes sense of his or her environment, but also how this environment shapes such meanings.
