From the Foreword:"This is a compelling and illuminating debate, conducted with a collegial spirit, into some of the most fundamental of human concerns. I found myself agreeing with Seachris, then Metz, then Seachris, then Metz, and so forth. That’s a sign of a good debate. In the end, I was sure that I had learned a lot, and enjoyed the ride!"John Martin Fischer, University of California, Riverside
