There could be a light that never goes out. The metaphysical possibility of disembodied existence

According to many philosophers, even if it is metaphysically possible that I exist without my present body or without my present brain, it is not metaphysically possible that I exist without any physical support. Thus, it is not metaphysically possible that I exist in some afterlife world, where I do not have any physical support. I shall argue against such a thesis by distinguishing two different notions of physical and by examining two strategies used by those who defend the thesis. No strategy will turn out to be conclusive. Thus, it seems that nothing excludes the metaphysical possibility of disembodied existence. Moreover, I shall illustrate two ways (respectively based on modal realism and on modal actualism) in which one might conclude that my disembodied existence is something more than a mere possibility.
