In this book, modern scientists and philosophers of science confront the prophetic legacy of the 17th century philosopher Leibniz-a metaphysical agenda full of ideas presaging today's state of the art research into relativity and quantum cosmology; the physics of force, mass, momentum, time and space; complexity and chaos theories; fundamental particles and multiple worlds; and of the electronic cosmos of our computer era. Their immense relevance to us is demonstrated by the engagement with them of over 200 present-day scientific minds. In essence this monograph comprises a survey and critical comparison of interlocking texts, and will serve philosophers as a gateway into fundamental science from the angle of metaphysics, as well as scientists as a documentation of Leibniz's profound philosophical impact on their own fields.
