The standard model of Peano arithmetic is 0={} and S(X)=Xunion{X}; its objects are all finite sets.
The set of all objects in this standard model is infinite, even though Peano arithmetic does not refer to this set.
I fail to see any meaningful sense in which “”There does not exist a time T after the present such that I am not alive” has a “hidden reference to infinity” which is somehow avoided by saying “For any duration N and probability epsilon, there exists a longer duration M such that...”
The difference is that in my version, utility is assigned to states of a finite universe. To the extent that there is a reference to infinity, the infinity describes an abstract mathematical object. In your version, utility is assigned to a state of an infinite universe. The infinity describes physical time, it says that there is an infinite amount of time you will be alive.
The difference is that in my version, utility is assigned to states of a finite universe.
That’s true. You prefer to assign infinitely many utilities to infinitely many states of possible finite universes, and I allow assigning one utility to one state of a possibly infinite universe.
I think the reasons for favoring each case are probably clear to us both, so now I vote for not generating further infinities of comments in the recent comments feed :)
