In this groundbreaking book, David Deutsch argues that explanations have a fundamental place in the universe and that improving them is the basic regulating principle of all successful human endeavor. The book takes readers on a journey through various fields of science, history of civilization, art, moral values, and the theory of political institutions. Deutsch explains how we form new explanations and drop bad ones, and discusses the conditions under which progress, which he argues is potentially boundless, can and cannot happen. He emphasizes the importance of good explanations, which he defines as those that are 'hard to vary' and have 'reach', and argues that these explanations are central to the Enlightenment way of thinking and to all scientific and philosophical progress.
This book, originally published in 1973 to accompany the BBC television series, explores human evolution and scientific progress as expressions of humanity's unique capabilities. Bronowski discusses human invention from the flint tool to geometry, agriculture to genetics, and from alchemy to the theory of relativity. He emphasizes the connection between art and science, arguing that both stem from the same human spirit. The book also addresses the ethical implications of scientific advancements and advocates for a 'democracy of the intellect,' urging society to democratize knowledge and make science accessible to all[1][3][4].
In this book, Karl Popper discusses key issues such as the aims of science, the role of science in civilization, the moral responsibility of scientists, the structure of history, and the choice between reason and revolution. Popper argues against intellectual fashions like positivism and relativism, advocating for his own critical rationalism as a theory of knowledge and an attitude towards human life, morals, and democracy. The book is a compilation of some of Popper's most important work on these subjects, published in cooperation with the Central European University.
In 'The Fabric of Reality', David Deutsch explores a four-strand theory of everything, integrating Hugh Everett's many-worlds interpretation of quantum physics, Karl Popper's epistemology, Alan Turing's theory of computation, and Richard Dawkins's evolutionary theory. The book discusses the implications of these theories, including the concept of the multiverse, quantum computers, time travel, and the ultimate fate of the universe. Deutsch argues that these theories, when taken literally and jointly, reveal a unified, objective, and comprehensible fabric of reality.
David Deutsch is a physicist at the University of Oxford, widely considered one of the most profound thinkers alive today. He’s the author of The Beginning of Infinity and The Fabric of Reality, and a pioneer of quantum computing and Popperian epistemology, follow David on Twitter
