In ordinary life, it is usually not hard to know who you are and who you used to be. For a small group of children around the world, their knowledge seems to conflict with what modern science believes is possible. On this episode, we tell stories of unusual childhood memories to examine the nature of the self, and what needs to survive in order for a person to survive. We delve into the strange philosophy and science of personal identity, quantum physics, and belief in the afterlife. Guest voices include Barbro Karlen, Dr. Jim Tucker, and philosophers Alyssa Ney and Yuval Avnur. This episode is sponsored by Warby Parker. Visit warbyparker.com/hiphi to support the show.
