“There is something beyond the grave; death does not end all, and the pale ghost escapes from the vanquished pyre.
If one's form of existence is all there is, there is no basis for any meaning, hope, purpose, or significance to life (and existence).
Everything in one's existence would simply be a random change of fate at best, or an accident at worst.
One's life, and one's death, would not even matter at all.
The logical end of such, is onlydespair.
Moreover, one can forget about being decent or ethical, with no basis for any (and all forms of) dignity, rights, or liberty.
Have one discovered, then, the beginning, that one look for the end?"
