In a Prism that will air next week, the neurobiologist dropped a huge ethical bomb on me in the last minute of the interview. It was so frustrating. He was talking about how the practical implication of his work would be to erase memories and how he saw this as a potentially powerful treatment for PTSD. I so wanted to get into that, but I didn't have enough studio time left.

Maybe this is tangent to our conversation, but the ethics of science seems never to be as quick as the speed of its capabilities. At least he was very conscious of the danger and controversy that his work could lead to, but he also thought it could be a wonderful salve.

In the context of free will, can we have free will without memory or if our memory and history is being distorted?
