Consider death as a door. Thesis: there are only two rational accounts of it:
a.) When you walk through that door, there is absolutely nothing, not even yourself.
b.) When you walk through that door, you will experience something, but it could be anything.
Though each account has its own horrors and consolations, ultimately it’s hard to determine from a purely rational perspective which is more frightening. We easily smuggle consolations into (b.) that we can’t get from reason; e.g. it’s true that God is just and it is reasonable he will reward the just, but how does this tell us anything about the other side of the door? Such a fact remains the same irrespective of what side of the door you’re on, in fact, it would be true even if death did not exist. The ultimate justice of God demands that we exist later, but it does not demand we exist on the far side of the door; nor does it demand that there be no horrors there (for the same reason that it does not demand that there be no horrors here).
