Physicist and bestselling author Capra (The Tao of Physics
and The Web of Life) delivers another fascinating discourse that explores of the interconnectedness of all living (and some nonliving) things, from the first life form of protocells to the development of language, culture, social mores and customs, spirituality and the global economy. That may be a lot of ground to cover in one book, but Capra gracefully cruises from 3.8 billion years ago, which "marked the emergence of a universal ancestor from which all subsequent life on Earth descended" through the present. Capra moves seamlessly through the evolution of cognition and thought; in a total rethink of Cartesian notions, he suggests that "consciousness is not only a biological, but also a social phenomenon." Other topics include tool-making (which Capra calls the earliest form of technology), language development (which, he explains, developed as a secondary need to tool-making) and the social loops of culture. Readers would do well to heed Capra's remarkably unpreachy warnings about the depletion of natural resources. Here is a book that not only moves readers to think about the larger picture, but also places them squarely in the middle of it, as they travel the interlinking and continual loop of the "network."
