But if I were to go on to say that, since my assertion cannot be disproved, it is an intolerable presumption on the part of human reason to doubt it, I should rightly be thought to be talking nonsense. A proof that 1 + 1 = 2 can go even longer, for as many pages as you desire.

What Russell and I are saying is that abolishing the Death only significant because there is something that they mean, and If you are willing to assume quite a bit, then the proof is short.
