Philosophy professor Carl Craver from Washington University in St. Louis tackles some fundamental questions about the importance of memory. Is it our personal memories that make us distinctly human? Does our capacity for memory make us morally accountable for our actions? How does our ability to remember the past relate to how we think about the future? And where do all these questions leave people with amnesia?"Amnesia and Identity" first aired in fall 2012 as part of Hold That Thought's 6-part series on Memory.
