Certainly we can culture an embryo because we know what its basic requirements are. So too can adult humans exists beyond the earth's atmosphere because we know what is required for survival and we take some of it with us. Give the embyro what it needs and it will of its own accord develop into an adult. The embryo is self sufficient between conception into the fallopian tube and implantation in the endometrium. Any other cell cannot make itself into a human adult it requires intervention, the embryo does not. Any early loss of the embryo is due to a failure in its supression of menstruation.
All this had been said before, it doesn't further your argument that a molecule is a human person.
Also you cannot say that an embryo develops self sufficiently into an adult, I'm not sure what experience you have with infants but they are hardly self sufficient. It's also worth pointing out that infants below the age of two are not self aware, technically not sentient. They fail the mirror test that elephants dolphins and primates can pass. The human consciousness keeps developing until the late teens.
When exactly do you say that human life, or more crucially personhood begins?
It's a question that bothers me because there is no clear answer. A molecule is not a human, a cell is not a human, a foetus with a neural network is not a human but it is considered a higher form of life compared to a cell, and may even feel pain. Legally, we need a clear line cf. age of consent. I am happy with the current situation. And I do consider abortions after the development of neural systems to be killing. However, we already accept killing can be justified under the right circumstances.
All I am saying is that when the full diploid complement of chromosomes exist within one cell and their influence is noticeable, i.e. physiological change from an ovum to a zygote there exists human life.
So where is the line then? When almost all of the DNA is fused and only one base pair is missing is it a full human person? Is this clicking together of a dozen atoms really the deal sealer here? This molecule is now capable of holding all the human rights we ascribe to adults?
You display ignorance, only ex cathedra pronouncements on matters of faith and morals have infallibility.
Of course, how silly of me.
Certainly, to accede to their use would be tacit acceptance of their destruction and endorsement of their artificial creation.
So when anything fails we must destroy everything because to reuse something or recycle it is therefore endorsement of it failing? Embryo's get created artificially these days, it's routine, it help's couples who have trouble conceiving naturally, it is within the law now, I suggest you get used to it.
I think maybe you should also look up the definition of 'illicit' and what is this white noise about "unitive and creative aspects", what the hell does that mean?
Bah! Semantics. You honestly haven't been reading the answers I've given to others
You still haven't justified anything you just keep answering with white noise ala the following:
macgamer wrote:The sexual act can be broken down into two aspects unitive and the procreative. The unitive is the complementary union of male and female in the sexual act, also an expression of love, the procreative is the end purpose of that union of male and female, sperm and ovum: progeny.
IVF is immoral (prefer that to illicit?) because it separates sexual intercourse (unitive) from reproduction (procreative).
The word suits you better yes. However, again you haven't attempted to justify why it is so. Why is having sex without conceiving immoral?
This absent mindedness on my part is a severe sting. I remember now when this story came out and I was excited. Your point is, very humbly, taken.
Research for the sake of research that is the other reason. I was responding to something Frank mentioned
Research for the sake of research is the same thing. They both end up advancing our knowledge and advancing out knowledge is the only way to create new technologies and medicines. Directed research is a misnomer.
Frank wrote:Primates are not human, embryos, as I you are aware I am arguing, are.
No they aren't but it was you who brought them up. Also, being non-human does not mean being incapable of suffering or not deserving of rights and protections under the law.
Most of the DNA in a somatic cell is not expressed. In an embryo the majority DNA is expressed. An embryo is on the path to become an adult and its DNA is being used intensively. A somatic cell spends most of its existence in the dormant G phase and it never develops into an adult. Science makes observations and interprets them. We observe the characteristics of an embryo and it is entirely unique amongst any other cell it has the ability to become an adult human.

And yet more white noise? The difference between somatic cells and gametes are completely inconsequential here. IS A SINGLE MOLECULE A HUMAN PERSON?
