Abortion up to the day of birth does grate a little on me. But then, Ancient Rome allowed it for up to three years after birth. So my distaste for the notion is cultural rather than objective. It helps to be aware of stuff like that. Did you know that the Bible even includes instructions for a chemically induced abotion (Numbers 5:11-31) for women suspected of infidelity? Fascinating!
People love throwing around the word “science” as though that can provide some kind of moral guidance. Yes, the cells making up an embrio or zygot are a unique combination of their parents’ genes and therefore can be defined as a unique and individual human who is going to die some time in the next 100 or so years regardless of what laws we pass. Genetic science can show that conception results in a new and unique human set of DNA. It can also show that the majority of fertilised eggs are naturally passed from the body and die, and of those that do manage to attach the the ureteral wall, well over half self abort within a few weeks under natural conditions.
The question really isn’t “Is this life human?”, as it clearly is. The real question is who gets to decide whether this individual human life should continue? Is it the parents or is it the government?
