Pro-choice activists are making a big deal about a new study claiming to show that human beings feel no pain until about 24 weeks into their fetal life. Lots of studies have appeared contradicting each other on this, so this is hardly news. There’s been lots of debate on this for several decades now, and this doesn’t seem to me to have acquired some special status above all the other studies yet. Science doesn’t work that way. As Ken Miller is fond of stating, you need established confirmation by further studies by people with different methodology before you accept something as established science. You need consensus. This is one study among many, and they don’t all agree with each other.
I’m still not sure how it’s relevant, anyway. I know of no fully pro-life argument claiming that it’s the consciousness of the fetus that makes abortion wrong. There are some moderate pro-choice arguments that restrict the period of abortion to early term that use this claim as part of their basis. But those who base their opposition to abortion on the fact that it’s a human organism with its own DNA and thus a full human being with full moral status will be unmoved by this, and those who base their opposition to abortion on the fact that abortion robs the fetal human organism of a future life like our lives will also be untouched.
