>Out of curiosity why did you change your mind? Did you get weary?
There was nothing explicit that I rejected in liberalism. I was a teenager; I was changing my politics (and my religion, my planned career path, my true love, etc) every day (or more realistically, every year at least). I moved from mainstream liberalism to Marxism, from Marxism to anarchism, and I've been an anarchocommunist now for about 10 years … although some of my priorities have still changed over that time.
>Your DNA argument is honestly splitting hairs.
You're the one who brought up DNA, not me. If your only point is that DNA would be a good, mostly airtight legal definition of individual personhood, and not that it would be any better for a woman to kill her clone than to kill her natural fetus, then … well, then I'm relieved, because the latter position seemed too silly for you! (But disagree that DNA would be a good legal definition of individuality, as it has far too many loopholes; besides twinning and chimerism, you could do a reverse tooth trick and claim that you were in California —since your DNA was— when you were really only in Texas.)
I did bring up the individuality of the blastocyst, and I stand by my claim that a blastocyst is not an individual. Blastocysts can (naturally by chance, or on purpose in the laboratory) be divided into two (monozygotic twinning), and two blastocysts can be combined into one (chimerism). Whatever rights this mass of tissues (and it is a mass of tissues, no brain waves, no heart beats) may have, it doesn't work to think of it in the same way as we think of born individuals. I do think that there are moral issues in killing a fetus (even though I don't think that the state should interfere), but I don't have any qualms at all about killing a blastocyst.
>Things can communicate in other ways. For instance:
>-We know the fetus is alive and has ongoing biological processes
>-Almost every form of life with ongoing biological processes is actively attempting to prolong its life and avoid death.
This is the only thing you've said that really repulses or scares me. My body is undergoing a lot of automatic biological processes, but don't you dare take those as cues to my will and try to impose that hypothetical will on me! You've already rejected the idea that I might have the right to choose to die, but at least you rejected that on the grounds that it would hurt other people; you didn't have the gall to say that, since my body is undergoing biological process to fight off death, that I really want to live. Whenever I have sex, I take care to ensure that I don't procreate; you can bet that my physiological processes are all working the other way. In the past, I have chosen to undergo surgery; when the scalpel entered, my body started physiological processes to prevent what it naïvely believed (I say ‘believed’ metaphorically) to be a deadly assault. But *I* did not want to prevent that assault; I *wanted* it to happen (because I believed that, with proper care, it would make me stronger in the end). Don't you listen to my biological processes; listen to *me*!
I know that the case of the fetus is different, and hopefully you're willing to listen to what I say and let me override what my physiology says, whereas with the fetus you defer to the physiology only because you have no other way to communicate. But given how independent my will is from what someone would assume based on what my body does (sure, we both want to live, but sometimes that's about the only thing that we have in common), I think that it's completely inappropriate for the state to assume that a fetus (and certainly not a blastocyst, which doesn't even have a brain) wants or cares about anything.
As I mentioned above, I *do* think that there are moral issues in killing a fetus (although not a blastocyst). What you have said *should* give people pause, and make them think and perhaps be unsure whether they want to go through with such a thing. But the state needs compelling evidence to interfere, not these vague hypotheses, at least according to my political philosophy.
>It might have been you
Yes, that was me.
>It is not the same thing, though, to call a sperm or egg cell a person. You need two to fuse in order to make one person. Therefore... at best, you could call it half a person.
No, I don't agree with this. This is another symptom of what I call ‘DNA fetishism’, thinking that genes are what make a person. The difference between an unfertilised egg and a fertilised egg is a small part of genetic material; the difference between a sperm and a fertilised egg is huge. Genetic material does not define life; most biologists consider bacteria (being cells) ‘alive’ and viruses (only genetic material, possibly with a protein coating but no internal metabolism) ‘not alive’; to some extent, this is just a matter of arbitrary semantics, but there is still a big difference between these. A spermatozoon is a complete living cell, but it is a cell that is eaten by the egg, except for the DNA. It provides half of the DNA (and a tiny portion of protein and fatty acids) to the fertlised egg; the unfertilised egg provides all of the rest.
Drawing the line at fertilisation is as arbitrary as drawing the line at birth.
And I do agree that drawing the line at birth is arbitrary, as a moral matter. (Unfortunately, it's as orathaic said, the development of a new person is gradual, and there is no obvious place to draw the line.) It's not arbitrary as a legal matter, however. To prevent infanticide, you don't have to assault the mother; you just pick up the infant and leave. But to prevent abortion, you do have to assault (restrain) the mother. So birth is a good place to put the matter into law. Especially now that we have Safe Haven laws throughout the United States (I don't know about other countries), the state (if it allows all abortions, as in California) has a reasonably coherent position: you can abort a fetus or give an infant to us if you don't want it.
>You seem to rely more on the consensus of the public rather than the actual truth.
I can't imagine why you say that. I think that my views are quite unusual; they line up with the mainstream pro-choice movement on the matter of what would be a reasonable law, but not always for the same reasons. For example, I never said anything about a ‘potential person’; that's not language that I use.
>Consider this: until this whole abortion movement began, abortion was seen by all as repugnant - it was baby-killing.
And who said that baby-killing is repugnant? Most human societies in most of human history have accepted infanticide. Knowing this, I can hardly call Persephone a monster (not that you did either, I know) for allowing infanticide while the umbilical cord is attached; anyone who calls that monstrous is either ignorant of history or doesn't know what ‘monster’ means.
All right, but *our* society considers baby-killing repugnant. How about abortion, then? Until the 19th century, there were no laws against abortion in the United States or England. Before that, the common law protected a human life only from the moment of ‘quickening’ (when the fetus starts to ‘kick’), although it still did not consider abortion to be murder. This ‘whole abortion movement’ began with an *anti*-abortion movement in the 1820s, which achieved victory about a century later, and then returned with a decriminalisation movement in the 1960s. This movement was victorious (in the U.S.) in 1973, but now the pendulum is swinging the other way. Even during the decades when abortion was illegal through the U.S., there were always people underground who helped to provide it and did not consider it repugnant (although you can say that about anything that's illegal).
>I think it is important to realize that technology is a construct and does not represent the "natural" world, which is what we should base our behavior on.
In the "natural" world, infanticide is common. Not only among non-industrial human civilisations, but also among animals. In fact, I would say that it's more the norm than the exception! (Not that most individuals commite infanticide, but most societies —human or otherwise— accept it.) When considering our behaviour, we must always remember the facts, that we came from nature and are still part of nature. But we should not let that cloud our moral judgement.
>You'll probably say we should also fight over resources and fight for mates and all too, since that is also natural. Well... newsflash, we do.
I would only say that saracstically, of course. Are you saying it earnestly? Just because it's "natural"?? And you call yourself a liberal???
I understand (I think!) and agree with your last paragraph. Actually, I would say that ‘everything is real’ is not just something that might not be true, but something that is in the end meaningless. I appear to be immersed in a world, I call that world ‘reality’, and I'm not concerned with whether it might be fake at some higher level of meta-reality that I can't in fact perceive.
