The Structure of Reality: The Science of Parallel Universes

The book by British physicist and philosopher David Deutsch, one of the creators of the concept of quantum computing, vividly demonstrates that the era of great philosophical systems has not been left in the past. The author presents a coherent and scientifically aligned answer to one of the most fundamental philosophical questions: what is the true nature of reality.
According to Deutsch, the fabric of reality, as it is revealed to any rational being, is woven from four main threads. These are the epistemology of Karl Popper, which uncovers the path of scientific knowledge; quantum mechanics, which is coherently interpreted only after recognizing the reality of the multiverse—an infinite ensemble of parallel universes; the computation theory established by Turing, without which understanding the nature of mathematical objects is impossible; and finally, the universal theory of evolution, which explains the development of not only life but also civilization.
The thoughtful reader will be struck by the combination of the author's breadth and logical consistency of thought. With his explanations, the multiverse stops seeming like science fiction and becomes the most natural description of the astonishing reality revealed to us by modern science. The question of the place and role of humanity in such a peculiar world remains outside the scope of the book. This topic is addressed in another work by David Deutsch—«The Beginning of Infinity», which serves as an organic continuation of «The Structure of Reality».
