Abstract
A very felicitous translation of a work of major importance for science and philosophy. The book attempts to provide a coherent vision of the process of evolution starting from the formation of our planet through the emergence of life, and later, thought, to an imagined end state or Omega Point. The book is rich in imaginative theories about the various transitions of evolution but its greatest merit is in providing an overall pattern of high plausibility rendering the past more intelligible and the future, in some measure, predictable. The central concept of the book seems to be that the energy present in each element of the universe is divided into two distinct components: a 'tangential' energy which links the element with all others of the same order of complexity and a 'radial' energy which draws the element towards ever greater complexity and centricity. The elaboration of the concept of 'radial' energy gives this book its great originality.--D. D. O.
