In Roe v. Wade, Associate Justice Harry Blackmun, speaking for the majority, said the Court was unable to determine when life begins. He wrote: ‘‘When those trained in the respective disciplines of medicine, philosophy, and theology are unable to arrive at any consensus … the judiciary, at this point in the development of man’s knowledge, is not in a position to speculate as to the answer.”

So since we’re skeptical about when life begins, it should be the mother’s decision right? Well, no. Philosopher Peter Kreeft argues that “abortion agnosticism” is actually a reason why we should be pro-life, not the other way around.

In this video, I take a ten-minute snippet of Kreeft’s quadrilemma and set it to an animated whiteboard video to help drive Kreeft’s points home.
