Arguments for and against abortion choice can get complex extremely quickly. I wouldn’t be able to do a PhD in the ethics of abortion if that wasn’t the case. But there is a simple argument against abortion that everyone who is pro-choice must face and have good reason to reject. I’ve outlined it below.

  1. It is morally wrong to kill innocent human beings.
  2. A fetus is an innocent human being.
  3. Abortion kills a fetus.
  4. Therefore abortion kills an innocent human being.
  5. Conclusion: abortion is morally wrong.

Let’s leave the first premise for a moment, and examine the second. Certainly, a fetus is innocent, more so than any other human being. It hasn’t had a chance to be otherwise – it isn’t guilty of anything, other than existing. And that’s not its fault! Some people might argue that a fetus isn’t a human being (this is in a biological sense), but that’s difficult to sustain – just check an embryology textbook. If you want something more technical, try this academic discussion on whether human organisms start existing at fertilisation.

Okay, so the second premise can’t be denied by any reasonable person. The third point is obviously true, and the fourth point follows directly from the second and third, so if you accept the second and third premises, you have to accept the fourth. It’s time to look at the first premise – if this is also accepted, the conclusion – that abortion is morally wrong – must also be accepted.

Is it always morally wrong to kill an innocent human being? The only way that abortion isn’t morally wrong is if this premise is rejected. It commits you to agreeing that sometimes, it’s not wrong to kill innocent human beings.  That’s a big step to take! You would want to have very good reasons for believing this! What if you are wrong? There can’t be many bigger moral errors you could make if you are mistaken!

So in the end, this argument comes down to a challenge. What reasons can you give that would make it okay to kill an innocent human being in some circumstances? Are you confident these are good reasons? How confident? A comparison with the death penalty is instructive. In the United States, the average time spent on death row after being given the death penalty is over ten years. Why so long? Because there is widespread agreement that every avenue should be explored to ensure that condemned prisoners are guilty. No-one wants to execute someone who is innocent. There have been 162 exonerations since 1973 at the time of writing. That’s about 1.6% of death row prisoners, but it’s enough to cause serious concern about the death penalty, as it prompts the question, how many were innocent that we don’t know about who were executed? Even a single person wrongly executed is too many.

But do we apply a similar degree of commitment towards the unborn? How certain are you that it is okay to kill innocent human beings? 99% 50%? Even philosophers disagree about this issue! Unless you are highly confident of your reasoning, prudence would suggest taking the safe option, especially since abortion takes millions of lives annually, not the hundreds taken by the death penalty. The safe option is to assume that it is morally wrong to kill innocent human beings unless a compelling case demonstrating otherwise is provided, one that is highly certain to be correct. If you do feel you have such a compelling case, I’d love to hear from you.

I’ve tried to anticipate some of the most common replies here.

  1. Pro-abortion minded people use the term “person” and say that a fetus is not a person (a legalese term). They do not deny the humanity of the preborn child, but tell us that he/she does not have rights since he/she is not a “person”. It’s nonsense.

    1. I have encountered pro-choice people who deny the biological humanity of the unborn, or at best, they say there is no scientific consensus on it. So we do have to be prepared to offer a response to those people if we encounter them.
