Like Percy said: a matter of definitions.
I think that I can make a decent case that a 32-cell morula is not the same thing as a seven-pound baby. I think I could reasonably say that a microscopic ball of 32 cells is closer kin to the zygote it came from - a single cell formed from a sperm entering an ovum. And that ovum is mighty similar, except for the number of chromosomes it has, to a unfertilized ovum. A couple of millions of those get flushed down the toilet daily, just here in the US - and, for that matter, a great many zygotes, morulae, and blastulae do too: a big percentage of them never implant in the uterine wall for perfectly natural, non-medicine-induced reasons.
I will cheerfully buy into the notion that a 30-week fetus is closer to a seven-pound baby than to a morula. Modern medicine can make a lot of those little preemies survive, yes, but it is a mite expensive. And I'm not real comfortable with experiences like those of a good friend of mine, who struggled through a pregnancy on bed rest and doctor's care because her body kept trying to reject the fetus. He was born alright, but with the apparent mental and physical abilities of an eggplant. He lived about fifteen years under constant care, and then died. That's a more serious tragedy than a D&C at eight weeks along.
Shadow, I would imagine that you think there is something called a "soul." I know the Catholic Church thinks so. Is there any evidence for souls, or any evidence as to when they enter a zygote/morula/blastula/embryo/fetus/infant?
