Actually, after having read the article and its follow up, I suppose you were referring to the revisit.
(The end of the first article pointed out brain wave activity first occurs at about 25 weeks, though I heard in a lecture that the foetus is capable of feeling pain at 8 weeks… At any rate, I think conception is even more arbitray than the other incidences).
It’s important to note that rape has been used as a tool of warfare and subjugation of women for centuries, if not thousands of years. The principle is that the native men, if they are not annihilated, will have to devote their resources to raising children that they are not certain are their own. It also provides a pastime for marauding soldiers that have been desensitised to the individuality of the population they are oppressing. However, I do not think those are good arguments in support of abortion.
I originally added this in to the above post, so I’ll post it here again since it furthers the argument:
Of course, since even the Pope holds that evolution is true, I figure that its a more reasonable position to hold that the sex drive evolved as a method of ensuring the propagation of the species and that our various paraphilias developed as a result of “misappropriation” of that instinct, much like charity is a “misappropriation” of the evolutionary drive towards caring for one’s offspring and kin. Evolutionary theory is even versatile enough to offer an explanation of how behaviour that is non-generative could be selected for (by increasing the genetic success of kin). Oh and a disclaimer as well, I hold that memetic inheritance rather than genetic inheritance is far more important in human societies. Passing on ideas conducive to the survival of the species is a far higher virtue than rape, for example. So whether or not one procreates doesn’t phase me… That got very tangential.
Thus I think it’s more important that children are instilled with moral values from a young age than that they happen to share about 50% of your genes, jumbled up at random. The economic argument is also not a good one: if a woman begins pregnancy in solvency and some time post-partum realises she cannot afford to continue raising the child while maintaining a decent standard of existence, she does not have the right to kil the child. I am not a woman so do not have to face pregnancy, but it seems the only moral option in both cases to put the child up for adoption (another complete tangent: there are studies like Bos’s 2007 one which show that gay parents are just as effective as other parents, so allowing gay couples to adopt would be a partial method of approaching the resulting increase in children that cannot be raised by their biological parents).
Anyway, the reason I made rather long and perhaps irrelevant posts was because I couldn’t determine your own stance. For example, I’m not entirely certain of whehter you hold a position of cultural relativism. While I believe in multiculturalism, that individuals should be free to believe in whatever they want, I don’t believe that people should be free to act however they want based on geography. I think almost all humans have the same goals (mainly wanting to be free from pain and capable of pursuing pleasure). Certain laws arising from various cultures are not conducive to that and some are particularly harmful in that regard. For example, I think any reasonable person must hold that laws enjoining the death of homosexuals or apostates are more harmful to the previously mentioned universal desires than not.
Edit: Gosh, sorry for the triple post.
