Right, you won't be here. But, again, not being here means no subjectivity, and all I know is limited to subjectivity. Therefore, nonsense term.
I don't mean "nonsense" in the self-contradictory sense. I mean it in the sense that there is no way whatsoever for me to understand the meaning of the term when applied to myself, because I only understand it with reference to other objects.
Nietzsche would disagree. Of course, I don't think this is egocentric at all. Quantum mechanics or not, it's purely possible from a philosophical standing that his "eternal recurrence" is true: that every atom relates to itself in an infinite number of ways across an infinite length of time (yes, we're making some leaps with apparent physical theories regarding the universe), meaning that my existence as I've known it will repeat an infinite number of times -- and (what Nietzsche and his scholars don't seem to hit on) that (if materialism is true) I'll also experience every possible different angle of this life as I know it given the infinite number of combinations of atoms involved.
Again, not egocentric. Philosophically possible, but very much a stretch (Miguel de Unamuno rightly said that the doctrine of the eternal recurrence was Nietzsche's way of gaining eternal life), surely. The point is that it solves the anxiety-arousing nonsense involved with subjective nonexistence.
