Book excerpt: This book explores old and new hopes that have emerged in the human quest to defeat death. On the one hand, it answers questions such as: Are we just physical machines of great complexity, with the brain as the hardware on which consciousness operates as its software? If so, can we speculate on ways in which the mind could be uploaded to a machine and no longer suffer the frailty of this biological body? And could an android robot or a mindfile in a computer simulation be conscious? On the other hand, the book examines the hope of survival through reincarnation according to the teachings of Eastern religions and New Age thought. All these topics are discussed from the perspectives of Christian theology and the philosophy of mind. This dual investigation will help Christians formulate a coherent response to old and new challenges to their faith.
