The twenty-first century has been dubbed the 'Biotech Century'. The explosive increase in our knowledge of the human genome continues to fuel speculations on the possibilities of human genetic modifications. This has been greeted with either enthusiasm or anxiety, for alongside the many euphoric pronouncements about potential benefits are serious questions about the impact of biotechnology and the prospect of manipulating molecular information. What impact will breakthroughs in genetic science will have on our understanding of the human person and the shape of human society? Is the significance of the human person reducible to his or her genetic make-up? What part do our genes play in determining human behaviour, and how would this affect our understanding of human freedom? Drawing on an international panel of writers representing different disciplinary perspectives and a number of Christian traditions, this book seeks to assess the impact of recent developments in genetic science on the Christian understanding of the human person. The essays in this volume address these concerns.
