One of our not-so-secret missions at ERI is to help pro-life advocates to think well about philosophy as it relates to the abortion debate. The problem with scientism is it says that philosophy isn’t a valid way to reach truth or discover facts. According to this position, our philosophical case for the unborn doesn’t matter, because only science really matters.

Now, if scientism was true, we would have to drop our strong philosophical arguments and just talk about biology. Biology and embryology can be helpful in articulating the pro-life position, but we don’t think they can get you all the way there. Just knowing that the fetus is human doesn’t tell us how to think about it. But scientism is false—more than that, it’s self-defeating, as I showed in the first article in this series.
So, How Far Can Science Get Us?
This is important, so to say it again: scientism does not equal science. Scientism says that arguments don’t matter, only bare scientific facts. Science stems from philosophical foundations. It answers questions about the world while using basic rules of logic to do so. This makes it a second thing, not a first thing, but scientism pretends that science is first and only. As C.S. Lewis writes:
“You can’t get second things by putting them first; you can get second things only by putting first things first.”
If we pursue science as first (scientism), then we lose science in its proper place.
And science in its proper place gives us good and valuable facts which can support various arguments in the abortion debate. We cannot say, with the justices playing make-believe about biology in Roe, that we don’t know when life begins. 96 percent of biologists (not just embryologists, mind you) agree in acknowledging that life begins at conception.
The study of embryology expands on this consensus by telling us what happens at and after conception. An individual human being develops from a single-celled organism into a recognizable baby, maintaining biological integrity and continuity the entire way. We can detect early cardiac activity; we can observe the differentiation of stem cells; we can see movement and interaction. And science adds new discoveries, such as the likely pain threshold for prenatal humans recently being pushed back from 25 weeks to 12 weeks.
