As a radiologist, I look at the interior of the human body every day, but have yet to see a soul. That does not mean it doesn’t exist. Taking the fact we cannot locate the soul on a CT or MRI scan as proof that it does not exist is as problematic as suggesting that the flaws in MacDougall’s experiment disprove the existence of the soul. Indeed, seeking physical evidence to prove the existence of the soul flies in the face of a great deal of philosophical and theological scholarship.
