Dr. David Comings, an internationally renowned physician, human geneticist and neuroscientist, proposes that spirituality is genetically hardwired into a specific part of the brain, is pleasurable, is critical to the evolution and survival of man, and will never go away. It strives to allow readers to develop a rational spirituality in which the fact-based rational brain and the faith-based spiritual brain can live in peace. In an era when politicians are judged on the basis of the strength of their belief in God, when schools are urged to teach Intelligent Design, and when religious terrorists threaten the existence of Western civilisation it is critical to dispassionately examine the question -- Did man create God? A wide range of issues are examined including intelligent answers to intelligent design; the relevance of modern cosmology to the existence or non-existence of god; the role of genes in spirituality; innate morality, the problem of evil, and many others. Michael Shermer called this the most detailed and up-to-date science ever generated on the subject of religion and suggested it will be the definitive scientific reference on religion for some time to come. This book is for those who have also questioned any part of their faith but treasure their spirituality and want answers that are not hostile to spirituality or religion.
