Yes, I think I can see the point being made by Peter and Galen. They suppose that beings must act based on how they are now... and I guess I just do not see why it could not be that "how they are now" presents a set of live options from which they may freely choose. I could see how no being would possess limitless options at any single point in time but not why they must have none at all.

Also, it is true that every person would acknowledge that he at least has the illusion of free will (which is strange enough if we do not). If it were true that we do not freely make choices nothing we think or do would be of any significance whatsoever. Even deciding to believe that determinism is true would be meaningless! Therefore, since free will is a necessary condition of meaningfulness in life, it seems best to assume we have it. If we do not then life is meaningless and who cares?
