This book engages critically with some of the major assumptions of prominent Transhumanists such as Nick Bostrom of Oxford University and Stefan Sorgner of John Cabot University at Rome. More broadly, questions concerning the complex relationships between society, technology, and ethics are widely explored. Important thinkers such as St. Augustine, Nietzsche, Bertrand Russell, and C. S. Lewis are enlisted to highlight and support the main arguments presented by the author. The book aims at a general readership interested in the current claims and possible outcomes of the Transhumanist and Posthumanist movement. It strikes a cautionary note about humanity's reliance on emerging technologies, particularly their potential to enhance and, eventually transform, human life span, cognition, and emotion.
