Yannaras's book is an important contribution to the theology/science debate. It offers a respectable alternative to creationist resistance to materialistic evolutionism. It shows how spiritual reality transcends the categories of chance and necessity that materialists believe can explain everything. It argues passionately for the priority of relationality and reciprocity, the spiritual dimension through which we can discover God's causality and so enter into personal relation with him.
