The closest the Bible gets, as far as I remember, is the bit in Genesis about the Tree of Life, and that's pretty ambiguous. It's been a while since I've read it, though.
I'm not actually sure, but I think this is mainly a hubris thing. For whatever reason, there's a fairly well-defined set of activities in our culture that are thought of as outside the proper domain of humanity; this might have gotten its start in a religious context, but it's certainly not limited to that anymore. (Consider "frankenfoods".) Seeking immortality's on that list, along with playing with the building blocks of life or, worse, creating new life; doing any of these things seems to be considered usurping the role of God or nature, and therefore blasphemous or at least very close to it. This is, of course, nothing new.
Where we get that list from is another question. I don't think it's purely Christian; cautionary tales about immortality go back at least to the Epic of Gilgamesh, although as far as mythological treatments go I think the Cumaean Sibyl's has more punch.
the bit in Genesis about the Tree of Life
Lol somebody ate an apple once, now we're not allowed to live forever.
Even if that was real, I don't see cryonics as a means of living forever. Forever is a long time. There's no guarantee of that.
set of activities ... thought of as outside the proper domain of humanity
Now that's interesting. I wonder if that might actually be more of an instinct to avoid screwing up important things, or just common sense, than something that's religious. Even if it has been codified in religion, might it have originally ...
I heard that women are difficult to convince when it comes to signing up for cryo. In mentioning cryonics to a dying person, there seems to be a consensus that it's not going to happen. I encountered a post: Years saved: Cryonics vs VillageReach, which addressed my main objection (that the amount of money spent on cryo may be better spent on saving starving children, especially considering that you could save multiple children for that amount of money with high probability whereas you save only one life with low probability by paying for cryo). Now I'm open to being persuaded.
My first instinct was to go read a lot about cryo, but it dawned on me that there are a lot of people here who will want to convince family members, some of them female, to sign up - and these people may appreciate the opportunity to practice on somebody. It has been argued that "Brilliant and creative minds have explored the argument territory quite thoroughly." but if we already know all of the objections and have working rebuttals for each, why is it still thought of as extra difficult to get through to women? If there were a solution to this, it would not be seen as difficult. There must be something that pro-cryo people need for persuading women that they either haven't figured out or aren't good enough at yet.
So, I decided to offer myself for experiments in attempting to convince a woman to sign up for cryo and took a poll in an open thread to see whether there was interest. I don't claim to be perfectly representative of the female population, but I assume that I will have at least some objections in common with them and that persuading me would still be good practice for anyone planning to convince family members in the future. Having a study on persuading women would be more scientific but how do you come up with hypotheses to test for such a study if you have no actual experience persuading women?
So, here is your opportunity to try whatever methods of persuasion you feel like with no guilt, explore my full list of objections without worrying about it being socially awkward, (I will even share cached religious thoughts, as annoyed as I am that I still have them.), and I will document as many of my impressions and objections as I can before I forget them.
I am putting each objection / impression into a new comment for organization. Also, I have decided to avoid reading anything further on cryo, until/unless it is suggested by one of my persuaders.
Well, have fun getting inside my head.
