This is a book written by scholars for scholars, but with a broad appeal to the intelligent lay person. It represents the results of the meeting of 21 eminent researchers at the Papal Residence at Castel Gandolfo to explore topics of common interest for scientists, philosophers, and theologians. It presents a quest common to several disciplines of scholarly research, and therefore, can be read with fair comprehension by all interested individuals. In that sense it is not a scholarly treatise. It presents more questions than answers.
