You forgot "arbitrary" in there, too.

I'd say "The point at which it develops a sufficient brain and nervous system to be aware of its own existance and able to take and react to outside stimuli" seems a pretty specific and reasonable point.

Tell that to the couples who try for years to get pregnant, finally get the early tests done, celebrate having a child at long last, and then miscarry days later. Something tells me that they're not going to just shrug it off.

Apples and oranges. I'm saying, if someone can be pregnant, and have a miscarriage and not even be aware that either thing has happened, it provides an argument in support of the idea that for at least a short span of time, nothing remotely resembling a human is inside of the woman. The emotional investment in a discovered pregnancy of a couple trying desperately to concieve is an entirely different thing.
