'Barsky's groundbreaking book is of enormous importance to researchers in a wide range of disciplines who are concerned with the impact of technology, for good and for ill, on human bio-cultural evolution. The book is a major contribution to our understanding of this evolution and its implications for the 'progressive divorce from nature' that our cultural and technological development has entailed.'
