01 - L'accès à la conscience

Julian Jaynes's "The Origins of Consciousness in the Breakdown of the Bicameral Mind" is a controversial but influential work that proposes a revolutionary theory about the evolution of human consciousness. Jaynes argues that consciousness as we know it emerged relatively recently in human history, and that earlier humans experienced the world differently, receiving instructions and guidance from internal voices they attributed to gods. This "bicameral mind," Jaynes suggests, was a state of consciousness where the left and right hemispheres of the brain functioned more independently. The book draws on evidence from ancient literature and mythology to support its claims, sparking considerable debate among scholars. While its central thesis remains highly contested, the book's imaginative approach to understanding consciousness continues to inspire discussion and further research.

In *Consciousness Explained*, Daniel Dennett undertakes a full-scale exploration of human consciousness. He challenges the traditional, commonsense theory of consciousness and introduces the 'Multiple Drafts' model as an alternative to the 'Cartesian Theater' concept. Dennett draws on a wealth of information from neuroscience, psychology, and artificial intelligence to transform current theories about conscious life in humans, animals, and even robots. The book is praised for its accessible and engaging style, making complex scientific and philosophical concepts highly digestible for both experts and general readers.

In this book, Roger Penrose challenges the idea that human consciousness can be replicated by computers. He delves into various subjects including algorithms, Turing machines, complexity theory, quantum mechanics, and the basics of modern physics to support his argument that human cognition is fundamentally non-computable. Penrose discusses the limitations of Turing machines, the incompleteness of formal systems as shown by Godel's proof, and the necessity of a unified theory of quantum gravity to explain human consciousness. The book is a detailed and thought-provoking journey through mathematics, computer science, philosophy, and physics, making it a must-read for those interested in the nature of mind and the relationship between physics and consciousness.
