An experience must be a universal across times as well as across brains. This experience of being you, here now, would be numerically the same whenev… - Arnold Zuboff

What makes an experience yours is none of the specification of its content or of the particularity or other properties of its possessor. All that is required for an experience to be yours, to be 'mine', is that it be immediate in its character as its character is experienced within it, that it be first person. My pains are pains that are not remote like those that belong to another. My pains are those that are immediate. They have internality. They are experienced in a first person way. They are subjectively at the center of the world, here in me. But all real pains must be had with this quality of immediacy that makes them 'mine'. What could really be a pain without its thus hurting?

In all conscious life there is only one person—I—whose existence depends merely on the presence of a quality that is inherent in all experience—its quality of being mine, the simple immediacy of it for whatever is having experience. One powerful argument for this is statistical: on the ordinary view of personhood it is an incredible coincidence for you (though not for others) that out of 200,000,000 sperm cells the very one required on each occasion for your future existence was first to the egg in each of the begettings of yourself and all your ancestors. The only view that does not make your existence incredible, and that is not therefore (from your perspective) an incredible view, is that any conscious being would necessarily have been you anyway. It is a consequence that self-interest should extend to all conscious organisms.

[M]y self-interest reaches fully into the life of every conscious organism, each of which I equally am, and that the death of any one of these does not annihilate me so long as there still is any other conscious thing anywhere in all reality—since I will be that thing. And every experience in any time is experienced by me with all the same urgency of its happening now. All of it equally is mine and now.
