From the preface:
Current physics and cosmology have left us with a confusion of empirically-derived models which do not yet combine into a coherent structure and which are most often ad hoc. Wegener is surely right in believing that the only way to tackle this problem is to go back to the foundations, and he has used skills acquired in many different disciplines to show us that a coherent solution is now within our grasp. I thoroughly enjoyed reading his book.
