The essentiality of dignity

Start with this:

1. Dignity is an essential property of anything that has it.

2. Necessarily, something has dignity if and only if it is a person.

3. Therefore, personhood is an essential property of anything that has it.

Now, suppose the standard philosophical pro-choice view that

4. Personhood consists in developed sophisticated cognitive faculties of the sort that fetuses and newborns lack but typical toddlers have.

Consider a newborn, Alice. By (4) Alice is not a person, but if she grows up into a typical toddler, that toddler will be a person. By (3), however, we cannot say that Alice will have become that person, since personhood is an essential property, and one cannot gain essential properties—either you necessarily have them or you necessarily lack them.

Call the toddler person “Alicia”. Then Alice is a different individual from Alicia.

So, what happens to Alice once we get to Alicia? Either Alice perishes or where Alicia is, there is Alice co-located with her.

Let’s suppose first the co-location option. We then have two conscious beings, Alice and Alicia, feeling the same things with the same brain, one (Alice) older than the other. We have standard and well-known problems with this absurd position (e.g., how does Alicia know that she is a person rather than just being an ex-fetus?).

But the option that Alice perishes when Alicia comes on the scene is also very strange. For even though Alice is not a person, it is obviously appropriate that Alice’s parents love for and care for her deeply. But if they love for and care for her deeply, they will have significant moral reason to prevent her from perishing. Therefore, they will have significant moral reason to give Alice drugs to arrest her intellectual development at a pre-personhood stage, to ensure that Alice does not perish. But this is a truly abhorrent conclusion!

Thus, we get absurdities from (3) and (4). This means that the pro-choice thinker who accepts (4) will have to reject (3). And they generally do so. This in turn requires them to reject (1) or (2). If they reject (2) but keep (1), then Alice the newborn must have dignity, since otherwise we have to say that Alice is a different entity from the later dignified Alicia, and both the theory that Alice perishes and the theory that Alice doesn’t perish is unacceptable. But if Alice the newborn has dignity, then the pro-choice argument from the lack of developed sophisticated cognitive abilities fails, because Alice the newborn lacks these abilities and so dignity comes apart from these abilities. But if dignity comes apart from these abilities, then the pro-choice argument based on personhood and these cognitive abilities is irrelevant. For it dignity is sufficient to ground a right to life, even absent personhood.

So, I think the pro-choice thinker who focuses on cognitive abilities will in the end need to deny that dignity is an essential property. I suspect most do deny that dignity is an essential property.

But I think the essentiality of dignity is pretty plausible. Dignity doesn’t seem to be something that can come and go. It seems no more alienable than the inalienable rights it grounds. It’s not an achievement, but is at the foundation of what we are.
