I'm a new member here and this is my first post. This topic really caught my eye because I’d had a similar discussion a while ago with a fellow skeptic friend of mine.
I would personally be delighted if there were to be an afterlife, in much the same way that I would be delighted if I weren't a Muggle and could actually raise my wand and utter, "Expeliarmus" and have the person before me take a back flip and fall flat on the ground.
That said, I will most certainly not sacrifice any of my rational thinking at the altar of this belief. The fact remains - there is no evidence whatsoever of the existence of the afterlife, and thus, any longing that I might have for the possibility of existing beyond the grave or pyre remains just that... a longing.
However, the absence of an afterlife doesn’t really devastate me to any degree (though during contemplative moments, I, at the ripe old age of 23, find myself overwhelmed by the supreme tragedy of the fact that I won’t be around to find out whether Microsoft or Apple have the upper hand in 2100) and it doesn’t hamper my ability to live my life to the hilt.
My answer to the poll is thus ‘No’. The absence of an afterlife is a concept that I accept with a neutral sense of factuality. Apples falling to the ground do not cheer me (unless I have an irresistible craving for cider) and similarly, the complete termination of my existence when my mortal body ceases to function doesn’t cheer me either (in fact, I have the strongest hunch that just before I die, I will remember something that I wanted to do before I died and didn't.) The presence of an afterlife, on the other hand, is something that I would find cheerful, with the slight assumption of course that this afterlife were to be enjoyable and not fraught with the iniquity of roasting on a open flame.
