When does human life begin?

The fact is that we can turn a skin cell into an embryo (in a lab) by bathing it in hormones and nutrients. Just like you can turn an embryo into a fetus by bathing it in a certain combination of hormones and nutrients.

A LOT of proactive and positive interventions need to occur to turn anything (any cell) into a person. And since (at every stage) the thing that is involved is 'alive' (whether it's a skin cell or a germ cell or a sperm or an embryo), we need a discrete time when we're not allowed to kill it, but we also need a time when we can (or else we'd never be able to slough a skin cell).

I've been saying for a long, long time that a scratched skin cell is a human life and is a potential person. This means that there's a complete difference between killing a potential person and a person.

Chemical reprogramming of human somatic cells to pluripotent stem cells

Here we demonstrate, by creating an intermediate plastic state, the chemical reprogramming of human somatic cells to human chemically induced pluripotent stem cells that exhibit key features of embryonic stem cells.

Now, I'll grant that this isn't 'definitive proof' you can bathe a skin cell in nutrients to make it into a person ... but I also don't want us to do that experiment. The TL;DR is that 'potential person' doesn't mean what people think it means, or else every scratched itch is a genocide.

That may not be, but Dolly is pretty good evidence.

I don't use examples that require merging two different 'life forms' for this argument. The biochemist in me doesn't care about the difference, but those with a heuristic of a 'life force' do seem to care. So, transforming a skin cell into an embryo using viral delivery of genes means that the cell wasn't a potential person (in their heuristic). But bathing it in non-living chemicals is insignificantly different from what happens to an embryo in the womb when we force it develop.

But wit...what about a family? Moma Bear, Poppa Bear and Baby Bear.
 
My belief is that you can discard scratched skin cells if you can't provide the above for them and that there's no moral need to nurture force them into personhood through sequential treatments with hormones and nutrients

Wait I can clone myself after every itch?
 
cloning does add an interesting layer to this discussion. i'm also not convinced there is a coherent ethical argument against cloning generally.

creating a clone to harvest organs is some dark stuff, there are all kinds of ethical problems with that. but just making a clone, at all? the quality of arguments i've seen against it are pretty similar to the purely religious-based arguments against abortion...sometimes identical and amounting to "this weirds me out/i don't like this so i want to pass law saying you can't do it". i don't see how it's possible to take a pro-choice but anti-cloning stance and justify it in self-consistent fashion. if someone wants to clone themselves and has the means/tech to do it, what is the legal/ethical justification for stopping them, that would not also imply justification for preventing people from having kids?

pro-life + pro cloning also incoherent, but it takes more work to demonstrate that and i would also be very interested to meet such an individual. i expect this to be an astoundingly tiny % of people and a conversation with them would be guaranteed to be entertaining if nothing else.

The main complaint about reproductive cloning is that we do not really know the consequences, such the the person produced may have a very short expected life span or serious health issues. This is really unrelated to the arguments for or against elective abortion.

Other arguments that I have only just found out about with a google include:
  • Deontological
    • the child has a right to a unique genetic make-up
    • the child has a right to ignorance of the effect of one’s genome on one’s future
    • cloning violates the Kantian categorical imperative by treating the child as a mere means (????)
  • Societal
    • totalitarian regimes would use it to make super soldiers or something
    • cloning and designing our children will transform procreation into a process similar to manufacturing, thereby altering the attitudes of parents toward their children
  • Teleological
    • humans have a natural essence or telos which they are meant to fulfill or strive for in order to be genuinely human
I am not sure I really get any of these, but also seem unrelated to elective abortion.

My opinion is that none of these really matter. Once the tech has progressed to the point that it is possible, the urge to reproduce is so strong that some country will allow it and everyone who wants it will go there.
 
Usually the restriction on cloning will be framed around not forcing someone into existence if they'll be at a severe disadvantage. But, like I keep bringing up, we're allowed to make as many FASD babies as we want. Advanced countries will even subsidize it. But, there are few freedoms being restricted, since preventing cloning is not the same as directly affecting a woman's body via legal mechanisms.

Exactly.

well, not entirely unrelated. i think we established that health of the fetus or mother is one of the primary reasons abortions happen in 3rd trimester regardless of policy.

"we do not really know the consequences" in terms of health of most newborns in advance. certainly not before conception, and not for some time after. we have a good estimate based on past experience. not so much with cloning, but similarly no evidence against it.

Deontological
  • the child has a right to a unique genetic make-up
  • the child has a right to ignorance of the effect of one’s genome on one’s future
  • cloning violates the Kantian categorical imperative by treating the child as a mere means (????)

i could claim i have a right to horse-shaped flowers too, but there needs to be a good reason for this "right", rather than simply beginning with the conclusion that "x is bad" and working backwards to make statements which imply "x is bad".

also, the 3rd bullet point doesn't hold. people treat children as means vs not regardless of cloning.

Societal
  • totalitarian regimes would use it to make super soldiers or something

i don't think totalitarian regimes will care about our laws regardless, they will do what they want. a country that will detain/kill people for expressing an opinion they don't agree with does not strike me as one where cloning is the most pressing ethical concern. not to us, and certainly not to them lol.

Teleological
  • humans have a natural essence or telos which they are meant to fulfill or strive for in order to be genuinely human

this isn't even relevant to cloning specifically.

cloning and designing our children will transform procreation into a process similar to manufacturing, thereby altering the attitudes of parents toward their children

this is something at least worth considering, but it's not clear to me that it's necessarily bad.

i also anticipate some form of "designer babies" independent of cloning as soon as it's possible. i estimate that the moment these things are possible at scale/reasonable cost (aka within means of significant % of people) it will start with merely preventing debilitating disease or other issues. it will be very, very hard to ethically/politically argue that parents can't ensure their kid won't die a painful death after 2 years. but from there, some places will start offering strength or intelligence or w/e (if possible to that degree of nuance) and while there will be objections, i don't see how they can hold up legally across 50 states with any consistency.

i would also much rather this choice in the hands of individuals than the government, again.

on that note, risk of government mandating certain traits be in children is chilling, but that's a separate issue from cloning (absent further editing) being illegal/unethical in its own right.

My opinion is that none of these really matter. Once the tech has progressed to the point that it is possible, the urge to reproduce is so strong that some country will allow it and everyone who wants it will go there.

this i agree with, but on reflection i expect designer babies are a larger risk factor than cloning, unless for some reason a sufficient degree of nuance wrt them is unattainable.

But, there are few freedoms being restricted, since preventing cloning is not the same as directly affecting a woman's body via legal mechanisms.

this distinction isn't as obvious as it seems in reading quoted post, even generally. all kinds of legislation we readily accept influences our bodies via said legal mechanisms, and do so as directly as abortion legislation. these things can directly dictate where you sleep at night, whether you can go where you want, or what is physically done to you in emergency situations.

one could even make an argument that preventing cloning is worse, because its prevention is not being done with the justification of protecting another person. instead, it is more along the lines of the country legally preventing women from reproducing. there is no "person" other than the woman/potential clone source in this hypothetical. whereas with abortion legislation, you're at least attempting to demonstrate that the rights of one individual is at odds with another, and arguing the tradeoffs.

Usually the restriction on cloning will be framed around not forcing someone into existence if they'll be at a severe disadvantage.

this has two problems:
  1. it's not clear a clone will actually be at a disadvantage, at all
  2. it has horrible implications for reproductive rights generally if the logic of "will be at a severe disadvantage" is extended. for example, if the clone will be healthy, it's hard to believe it will be at a disadvantage in a wealthy family with strong education when compared to a randomly selected person near the poverty line having a child. and we've already demonstrated that children with single parents are at a big disadvantage...the implications if *that* were to be codified against are not something i'm comfortable with. even if i do believe we should stop incentivizing that situation, this is extremely different legally and ethically.
 
life begins when tmit decides its logical.
 
instead, it is more along the lines of the country legally preventing women from reproducing
Yes, correct. But the government forbidding cloning is going to be very different from government restricting a woman's ability to reproduce. They're similar, but at very dissimilar intensities of intrusion. Cloning an embryo is similar to IVT, but also quantifiably different, so drawing a line through the permissions is done easily and without any need for 'bothsidesisms'.
it's not clear a clone will actually be at a disadvantage, at all
Well, it's clear enough given the outcomes in animal experiments. Unfortunately, to get a clone that's 'acceptable', we would have to create ones that suffered unnecessary deficits while building up and testing the technology. The embargo is mostly due to the process of getting there, less the destination. Of course, evil jurisdictions will still do it and perfect the technology, so we will eventually have to decide if it was merely the process of learning to clone people that prevents us from cloning people.

it has horrible implications for reproductive rights generally if the logic of "will be at a severe disadvantage" is extended
That is why I took pains to distinguish it, so that it wasn't extended. But the current status quo of being allowed to create intentionally disabled children is also problematic, even if that's due to dilemmas when it comes to setting precedent.
 
The two industries that are usually first to exploit new tech are the military and the porn industries, so I would expect cloned, lifelike sex dolls to show up before the rest. :D
 
He's arguing against restrictions in his last post...

You're m i s s i n g t h e p o i n t
Aso re: cloning, can't believe no one has brought up the real reason for forbidding cloning. Have you never seen Star Wars Episode II: Attack of the Clones?
 
And cats.
:huh:

Birds have the ability to fly, which cats don't. As for mice, I don't care if my cat played "paw-ball" and batted the mouse against the basement wall and floor until it was dead. Mice are vermin.

You want to save birds? Lobby against the insane number of windows in skyscrapers. Birds see the reflection of the sky, don't realize it's a solid object, and kill themselves when they fly into it at normal speed.

Spoiler Legend :
Annual mortality of Canadian birds due to human activities (log-scale). Panel A shows stage-specific estimates for each activity, according to whether entire nests, single eggs/nestlings, or mobile individuals were killed, as in original papers and reports. Values include both means and medians, and error bars represent both confidence limits (90% or 95%) and maximum/minimum ranges, as originally presented. Panel B shows converted mortality estimates for each activity (median with 90% confidence limits), where stage-specific kill totals have been converted to the equivalent number of potential adult breeders based on a stochastic model incorporating species-composition and demography. Hollow symbols indicate mortality only estimated for part of Canada or for a limited number of species, and thus where total Canada-wide cross-taxa mortality is likely much higher than these estimates. Panel C shows these same converted estimates (median with 90% confidence limits), pooled across related activities (cats: feral and pet; transportation: vehicle-collisions, road maintenance, and chronic ship-source oil; buildings: collisions with all 3 types; power: transmission-line collisions, hydro reservoirs, electrocutions, transmission-line maintenance, and wind energy; agriculture: haying and pesticides; harvest: migratory and nonmigratory birds; fisheries: all gear types; oil and gas: all terrestrial and marine sources; mining: both pits/quarries and metals/minerals), as well as the original single-source values for forestry and communication towers. Values in all panels are ranked in descending order according to the converted kill totals. See text and Appendix 2 for citations of papers and reports used as data sources.
