Sir Roger Penrose was investigating non-computability versus computability in brain behavior. I am not sure he even mentions free will. This highlights some of the unfortunate tensions in this debate, where people may feel obliged to hold to a literal materialism along with a computational theory of mind, and vigorously shoot down anything that threatens to unsettle that somewhat dogmatic position, for fear of strengthening the position of fundamentalist religious believers. In short, it is primarily a political sentiment, not a scientific one. We should be able to follow where evidence and rational argument leads without being held hostage to such concerns which are strictly irrelevant to the debate.
