Life Before Life: A Scientific Investigation of Children's Memories of Previous Lives is a 2005 book written by psychiatristJim B. Tucker, which presents an overview of more than 40 years of reincarnation research at the University of Virginia Division of Personality Studies, into children's reports of past-life memories. The book also discusses "birthmarks and birth defects that match those of a deceased person who is identified by the child". The foreword to the book is written by Ian Stevenson.:256
This book claims that consciousness can be considered separately from the brain, which provides a basis for claims of reincarnation. Tucker discusses objections to reincarnation: the paucity of persons who actually claim to remember a past life, the fragility of memories, the population explosion, the mind—body problem, fraud, and others. Tucker states that none of the cases examined are perfect, and that "faulty memory by informants" is seen to be the "best normal explanation for many of the cases" reviewed in the book.:205-9 The version of reincarnation discussed is typically incompatible with common religious beliefs around reincarnation, specifically in relation to karma.
