This book is formidable work of philosophical synthesis. By introducing dialectical argumentation, it casts the problematic of analogous being in a new light. In the process it illuminates the main issues that arise in classical philosophy. The examination of the Pre-Socratics is especially important as introducing cosmological categories. These are taken up in a dialectical sequence that culminates in Kepler's Laws. The result is a metaphysical standpoint beyond mechanism. The physical world is understood not as a system of external relations but as an organic totality, self-determining and free.
