(wink here again. Just so you know.)
Traditionalists typically advance two arguments about suffering against annihilationists: 1) We merit infinite suffering (I'll probably deal with this point in a different post), and 2) People suffer differing levels of punishment in hell.
Point (1) is intended to prove that you can't have annihilationism since you can't suffer an infinitie amount without infinite time (again, I disagree, but that's for a different post). Point (2) is intended to show that annihilationism is false since there is only one result--annihilation without differentiation, and that contradicts the different levels of punishment shown in the Bible. (This point only works on annihilationists who believe that there is no period of suffereing before annihilation. It falls completely flat against those who do.)
Traditionalists run into trouble if they try to hold both (1) and (2). Basically, there are no real levels of punishment in infinite suffering. You might argue that person A's suffering is 5x more intense than person B's suffering. But when you multiply by infinity, it is exactly the same. 2 x infinity = 5 x infinity = 100 x infinity = infinity x infinity. So to argue that there are levels of punishment in infinite suffereing is to not understand infinity very well.
There are two defenses that I can see against the contradiction: 1) Cardinality. There really are some infinities that are larger than others. You could argue that Person A's suffering lasts for duration Aleph naught, while Person B's suffering lasts for Aleph prime. This strikes me as a distinction without a difference, but I suppose it would be technically true. 2) You could argue that suffering is qualitatively different at different levels--a pain that is quantitatively 5x worse is even worse in some uncountable way as well--it is a qualitatively worse pain.
I have never seen either argument made. Has anyone else?
