The Human Factor

This amazing book takes into account all of the leading premises of the modern concept of biocultural evolution and builds a bridge to religious theory. Its value lies in its ability to pose the major questions and sketch proposals for dealing with them. To my knowledge it is the first work to make such an attempt.

Hefner's book is a major breakthrough in doing constructive theology. His view of human beings as created co-creators is filled with balanced insight regarding how humans are united with the rest of creation, while having a special place because of their brains and culture.
