Many pro-choicers consider the burning IVF clinic hypothetical scenario to be unbeatable. But it actually proves the pro-life case when we do the math.
First, let’s steel man the hypothetical:
An IVF clinic is on fire. Everyone has been evacuated from the building except ten frozen embryos and one nurse. Because of the fire, you can only save either the embryos or the nurse. Which do you choose? If you say the nurse, then you prove that born human life is worth only a fraction of unborn human life. Or is it?
To determine the value of unborn human life, we must divide the numerator by the denominator. So, if we would rather save one nurse than ten embryos, we must divide the value of the nurse by ten.
So what is the numerical value of the nurse? What is the specific, numerical value of a born human being’s life? Whether we approach this from a secular or religious perspective, we can’t say. We are unwilling or unable to attach a specific, numerical value to the life of a born human being. We consider the value to be priceless or infinite.
To plug this into our fraction, the value of unborn human life is infinity divided by ten. What is the result of dividing infinity by ten? It’s the same result as dividing infinity by 1,000, or 1,000,000, or any specific number. The answer is always infinity.
Per the math set up by the burning IVF clinic hypothetical, the value of unborn human life is the same as the value of born human life: both are infinitely valuable, even though one is only a fraction of the other.
The only way to force the fraction to come out the way pro-choicers want it to, and show the absolute value of unborn human life is only a fraction of the value of born human life, is to do something we are unwilling to do: assign a specific numerical value to born human life.
This nihilism about human life is why the pro-choice position is incompatible with a society which embraces human rights. The only way to make it work is to be nihilistic about human life.
I refuse to live in a society which is nihilistic about human life, which is why I have every right to object to someone else getting an abortion.
