DD: I meant on the "day" thing. And I generally don't include Ephesians (for the notion of 'spiritually' dead/alive) in "Paul". ;)
JD: What I meant (and tried to explain) by "life goes on" doesn't require any "other plane" (nor does it rule it out, of course). And (yet?) I don't see it as a foe -- that's the point of my op.
Now your comment about the 'other plane' reminds me of Svidrigailov's in Dostoevsky's Crime and Punishment:
"I don't believe in a future life," said Raskolnikov.
Svidrigailov sat lost in thought.
"And what if there are only spiders there, or something of that
sort," he said suddenly.
"He is a madman," thought Raskolnikov.
"We always imagine eternity as something beyond our conception,
something vast, vast! But why must it be vast? Instead of all that,
what if it's one little room, like a bathhouse in the country, black
and grimy and spiders in every corner, and that's all eternity is? I
sometimes fancy it like that."
"Can it be you can imagine nothing juster and more comforting than
that?" Raskolnikov cried, with a feeling of anguish.
"Juster? And how can we tell, perhaps that is just, and do you
know it's what I would certainly have made it," answered Svidrigailov,
with a vague smile.
Elsewhere: for some reason -- I may be wrong -- I picture most anti-aging enthusiastic posters here (you, slimboyfat, BTS on another thread, leavingwt maybe) as relatively young men (not so many young women, apparently), at a stage in life where the desire to live forever can be just another expression of the desire to live (period). I find it very natural actually, certainly not "monstrous". An older person's approach to death may be different. Bergman's movie Smultronstället (Wild Strawberries) illustrates that beautifully. Or -- more illustrative of individual differences, more cruel too -- Imamura's Narayama bushi-ko (The Ballad of Narayama).
Aging kills -- of course. Living kills, too. From this perspective, everything mankind has ever achieved it has done with a 100 % mortality rate (diachronically as you presentt it). As I tried to point out in my op, every bit of human culture (including what you call "knowledge" and "intelligence") is part of a collective strategy to get around certain and never-too-remote individual death. My bet (or sci-fi scenario) fwiw is opposite to yours: remove danger, risk, fear, urgency, necessity, fatality out of man's existence, just feed him and entertain him without a deadline and you will get the worst, the dumbest, the ugliest out of him. Remember Harry Lime's line in The Third Man? "Don't be so gloomy. After all it's not that awful. Like the fella says, in Italy for 30 years under the Borgias they had warfare, terror, murder, and bloodshed, but they produced Michelangelo, Leonardo da Vinci, and the Renaissance. In Switzerland they had brotherly love - they had 500 years of democracy and peace, and what did that produce? The cuckoo clock." (No offence to the Swiss ;))
Satanus: Cf. Freud's Beyond the Pleasure Principle, about Todestrieb or "drive to death". In his Ecrits Lacan reworks this notion in a less biological and more "structuralist" way, and links it with a famous quote from Petronius: "Nam Sibyllam quidem Cumis ego ipse oculis meis vidi in ampulla pendere, et cum illi pueri dicerent: Sibulla, ti theleis; respondebat illa: apothanein thelo." (For with my own eyes I saw the Sibyl hanging in a jar at Cumae, and when the boys said to her, 'Sibyl, what do you want?' she replied, 'I want to die.) Somewhere Nietzsche corrects the notion of "instinct of self-preservation" with the slightly different idea that what a living being actually wants is actualisation of its potentiality, wasting itself as it realises itself.
