You may have seen a recent cover story on Newsweek in which Eben Alexander claimed that his experiences while in a coma provided evidence of the existence of heaven. For a neurosurgeon, Alexander seems to know remarkably little about how the brain actually works. This post by Steven Novella at Neurologica explains the brain science involved. Sam Harris also wrote a longer piece on Alexander’s story. I’m sure the experiences Dr. Alexander had were lovely, but I don’t think they had anything to do with heaven, except insofar as heaven is a state of mind.
