what would make you change your beliefs?

AtheistPhil -

What I mean is that if consciousness is physical, then losing consciousness would be like losing a limb. When you lose a limb, it's gone. But consciousness returns, just as it was, after being "lost".

consciousness is not a sum of physical objects, it's an event relying on physical things, one of the potential materialist explanation of the conscience is that it's a flow of electrochemical impulses between neurones
In that case conscience can disappear and reappear.
