You seem to know alot about what happens after death, are you dead?
It's called inductive reasoning. We know where thoughts are formed, and what they need to be formed, i.e., a working brain. There is no reason to assume death is anything but non-existence, and all the reasons to believe it is non-existence, based on everything science has told us so far.
I'd argue the desire to ensure the human race progresses after death on what some would consider a path of "englightenment" is connected to and derived from the more primal desire to ensure the survival of our species through recreation and survival instincts.
That's nice.
If there's no point considering existence after death because you believe it doesn't affect you after you die then why exist at all?
Because I like existing. What a hard question.
Are you now going to fall back on the excuse that the primal instinct to survive and reproduce justifies your existence without acknowledging my first points?
What are you even talking about?
Or are you going to come back stating how much enjoyment you derive from your existence, even if that enjoyment is partially derived from the primal instinct and desire to procreate?
I don't derive enjoyment from existence because of the "primal instinct and desire to procreate." Even if I did, there's a saying about bad masters and good servants.
If so then this rationale could at least on the very basic level be construed by some that you do infact care what happens after death because you desire to procreate and ensure the survival of the species
Yes, I'm sure an idiot could "construe" it to mean that, but that's why we'd call that person an idiot -- it makes no sense whatsoever. Enjoying life somehow turns into "desiring to procreate and ensure the survival of the species"? What? There's more to life than sex, you know, and even if sex were one of the main reasons for someone to be alive, that's still a non sequitur. If Bob enjoys sex because enjoying sex made his ancestors breed more, that doesn't mean Bob has the desire to procreate and ensure the survival of the species; it means Bob likes sex, which, in his ancestors, as a side effect led to those genes that make you enjoy sex being passed on.
Xant, give us your definition of happiness. It can't be the generic smile of a child, a loving embrace of a female, rainbows with other natural nonsense, on top of world's peace... I am genuinely curious.
Being able to do what I want to do. Mostly things that I find intellectually and physically pleasing, and those things include difficulties and struggle and competition, so I wouldn't want to be hooked to a heroin machine. The trick, I've found, is to pick and choose which one of your evolved instincts and traits you find acceptable and worthy on an intellectual level and then pursue things that align with them, while subduing the instincts and traits you dislike.
