Is Abortion Murder, Manslaughter, Criminal Negligence, or Allowable?

Here’s Justin’s summary:

The logic of the landmark abortion ruling Roe v. Wade was that ignorance about when human life begins entails that the government not impose restrictions upon abortion practice.

If you go back to August 16, 2008, Rick Warren asked presidential candidate Barack Obama when a fetus gets human rights, and Mr. Obama (who opposes any abortion restrictions for any reason, in line with Roe v. Wade) famously responded that the answer was “above his pay grade.”

Philosopher Peter Kreeft of Boston College helps us think through the logic of this position.

He makes the commonsensical point of formal logic that “either we do or do not know what a fetus is,” explaining:

Either there is “out there,” in objective fact, independent of our minds, a human life, or there is not; and either there is knowledge in our minds of this objective fact, or there is not.

The first set is an ontological claim (what is or is not); the second set is an epistemological claim (what we know or do not know). The result yields four logical possibilities:

  1. The fetus is a person, and we know that.
  2. The fetus is a person, but we don’t know that.
  3. The fetus isn’t a person, but we don’t know that.
  4. The fetus isn’t a person, and we know that.

What are the implications for these four positions? Kreeft analyzes them as follows:

Abortion in Scenario #1: The Fetus Is a Person and I Know That

In Case 1, where the fetus is a person and you know that, abortion is murder.

First-degree murder, in fact. You deliberately kill an innocent human being.

Abortion in Scenario #2: The Fetus Is a Person and I Do Not Know That

In Case 2, where the fetus is a person and you don’t know that, abortion is manslaughter.

It’s like driving over a man-shaped overcoat in the street at night or shooting toxic chemicals into a building that you’re not sure is fully evacuated. You’re not sure there is a person there, but you’re not sure there isn’t either, and it just so happens that there is a person there, and you kill him. You cannot plead ignorance. True, you didn’t know there was a person there, but you didn’t know there wasn’t either, so your act was literally the height of irresponsibility. This is the act Roe allowed.

Abortion in Scenario #3: The Fetus Is Not a Person and I Do Not Know That

In Case 3, the fetus isn’t a person, but you don’t know that. So abortion is just as irresponsible as it is in the previous case.

You ran over the overcoat or fumigated the building without knowing that there were no persons there. You were lucky; there weren’t. But you didn’t care; you didn’t take care; you were just as irresponsible. You cannot legally be charged with manslaughter, since no man was slaughtered, but you can and should be charged with criminal negligence.

Abortion in Scenario #4: The Fetus Is Not a Person and I Know That

Only in Case 4 [you know that the fetus is not a person] is abortion a reasonable, permissible, and responsible choice.

But note: What makes Case 4 permissible is not merely the fact that the fetus is not a person but also your knowledge that it is not, your overcoming of skepticism. So skepticism counts not for abortion but against it. Only if you are not a skeptic, only if you are a dogmatist, only if you are certain that there is no person in the fetus, no man in the coat, or no person in the building, may you abort, drive, or fumigate.

As scientific research advances, the facts are becoming clearer. Regardless of political leaning, we can be more certain than ever that a fetus is, in fact, a person whose life has inherent value from the moment of conception.

We hope this article enlightened and inspired you to stand up for life.

Despite the overturning of Roe v. Wade, abortions are still prevalent in our nation. As a response to the overturning, the media: from the news to entertainment sources to even political figures and celebrities, have pushed abortion as an ongoing agenda, shaping the way this generation thinks and acts. Misinformation is being spread every day, and people are sadly believing the lies.

Our articles and stories aim to tell one thing: the truth.

We know that it is both a blessing and a challenge to understand the reality of abortion, because knowledge incites belief, and belief incites action. But we’re in this together. We believe that we can make abortion unthinkable.

With your support, we look forward to a future where young women are empowered to fight for their own rights: a right to bring life into the world, to be fearless leaders, to be examples of hope, strength, and undeterred resilience. We look forward to a future where life can happen.

If this article strengthened your belief to reach women everywhere with the truth and to let life happen, then please consider helping us extend our reach by making a gift right now. Your gift of just $10 or $20 helps our mission to create a story of hope and empowerment for every woman facing an unplanned pregnancy.

We aim to create a culture that views “pro-life” as equivalent to having empathy and compassion, providing holistic care (before and beyond pregnancy) and education, and most importantly, choosing to speak and act in love. We are pro-life, pro-love, pro-woman, pro-solution.

Don’t just be part of the movement, be part of the solution, and give today.
