For me, drilling everything down into a chemical reaction makes life dreary.
For me, the prospect of this being the only world we've got frankly makes me want to hang myself. Or at least I would, if I had the motor skills to tie a knot. Because if there's nothing past this, then I have zero reason not to want to die.
That may be so, but it may just very well be the case that this is true, despite the fact that you may want more. What you want is
irrelevant to reality.
If you believe something (such as another world after this one, or the idea that we are in fact comprised of more than just chemicles) becuase it is comforting to believe it, that doesn't make the belief
true, and
in my opinion, it's not enough to substantiate beleif. I want to believe as many
true things and as few
false things as possible, regardless of whether these
true things are pleasant or not. I don't want any beleif system blowing sunshine up my ass.
