you’re not doing harm to a person by infanticide any more than you are by using contraception.
A man produces about 47 billion sperm a year; a woman releases 13 eggs a year; a couple that tries to become pregnant over the course of a year will have a 75% chance of live birth pregnancy if the female is 30. So each feasible sperm-egg combination over the course of a year has about a trillionth chance of making it to a live birth. *
As soon as conception happens, then you’ve got a zygote which is very likely to make it to live birth. And once it makes it to live birth, it’s very likely to make it to adulthood. So there seems to be a very bright line at conception. (Contraceptives prevent conception; condoms by preventing sperm from entering, the pill by preventing ovulation, and so on.)
(I should note that I think there are sound reasons to treat a risk that will end one out of a trillion people chosen at random as less of a concern than a risk that is certain to end a certain person, and that this line of reasoning depends heavily on this premise, but it would take too long to go into those reasons here. I can in another comment if you’re interested.)
*Noting that ‘potential resulting individual DNAs’ are individually much less likely than just sperm-egg combinations.
It is estimated that up to half of all fertilized eggs die and are lost (aborted) spontaneously, usually before the woman knows she is pregnant. Among those women who know they are pregnant, the miscarriage rate is about 15-20%. Most miscarriages occur during the first 7 weeks of pregnancy. The rate of miscarriage drops after the baby’s heart beat is detected.
So your bright line should be heartbeat, or at least zygote implantation. This does not significantly affect your conclusions.
The jump from 1e-12 to .5 seems brighter to me than the jump from .5 to .8. (.5 is also historically significant, as only about half of born children would live to see puberty for much of human history.)
One or two, but for me deciding which move to make is practically instinct, less lookahead. Also I’m not entirely sure how this is relevant.
What role should the future play in decision-making?
For me, it seems that if you’re confident that having more people in the world is a net positive, then as a necessary conclusion the moral thing to do is to try to have as many children as possible.
It is not clear to me that prohibiting murder derives from that position or mandates birth.
If you’re not sure of this, I don’t undersand how you can conclude it’s a moral wrong to destroy something which is not yet a person but merely has the potential to become one.
By quantification of “merely.” If we determine that a particular coma patient has a 90% chance of reawakening and becoming a person again, then it seems almost as bad to end them as it would be to end them once they were awake. If we determine that a particular coma patient has a 5% chance of reawakening and becoming a person again, then it seems not nearly as bad to end them. If we determine that a particular coma patient has a 1e-6 chance of reawakening and becoming a person again, then it seems that ending them has little moral cost.
If infants are nearly guaranteed to become people, then failing to protect them because we are impatient does not strike me as wisdom.
