I don't think that word means what you think it means

Technically I’ve missed Blog for Choice day, but it isn’t really tomorrow till after I’ve slept, and there’s something that’s been bugging me.

Why do people, even those who support abortion rights, talk about conception? It’s a pre-scientific concept. The Feast of the Conception dates back to the 7th century, long before anybody had any notion of how the mechanics of reproduction worked at a cellular level. It was clearly just a word that meant something like when life begins, so people who say “life begins at conception” aren’t actually saying anything meaningful.

People who try to nail conception to a particular stage of cellular reproductive development can’t even agree on which stage it is. Same say it’s fertilization, some say implantation, some say the whole period from fertilization to implantation.

Wouldn’t it make more sense to use actual scientific terminology when discussing matters of science? Personally, I think anyone who places the point of individual life beginning prior to gastrulation just hasn’t given the matter any serious thought.
