Siblings and moral theory

  1. We have special duties, independent of communal enactments, to take care of our siblings, precisely because they are siblings.
This is true.

Notice that (1) creates problems for a number of moral theories. Utilitarians will deny (1). The mere fact that someone is our brother or sister only makes it easier for us to know how to help him or her, which does not make a for a special duty to take care of him or her precisely because he or she is our brother or sister. It is difficult to see how Kantians could justify (1) without relying on something like a dollop of Natural Law (which Kant himself, but not so much contemporary Kantians, is happy with).

Contractarians can accept (1) minus the "independent of communal enactments" proviso. For perhaps it would be irrational for us to reject a communal tradition of a network of duties of special care that is below a certain level of onerousness, and our community's network includes siblinghood. But the contractarian probably could not object if the community instead had a network of duties of special care that put similar emphasis on, say, first-cousins-of-the-same-eye-color instead of siblings: what one gets from the contractarian structure is at most the irrationality of rejecting whatever one's community network of duties of special care is.

Divine command theorists can perhaps accept (1), though one might worry if the "precisely" in (1) is correct if this happens also because of divine command.

Natural law, of the well-developed moral theories, is probably the theory that best passes the test of fitting with (1). So, (1) provides a kind of argument for natural law theory (and to a lesser degree for divine command theory).

Does (1) matter? I think so. It is an important moral insight that somehow all human beings are brothers and sisters, but this moral insight is unhelpful, and maybe harmful, apart from (1).

How about a goal oriented moral theory, where the goal is human happiness ala Aristotle's eudaimonia? We all have various desires that drive our behavior. These desires are best fulfilled when in a state of eudaimonia. The best way to be in state eudaimonia is to adopt a moral life. It is not possible to be fully happy, without being a good person to the people we care about. Your siblings share a special bond with you, therefore you care about them especially. Since you care about them a lot, and its not possible for you to be truly happy while being an arse to your sister, and truly is what you desire most to be, then you ought to care for your sister.

Phew that was a long.I think its contingent on what eudaimonia is for a given person, but it seems like a reasonable suggestion that its nearly universal amongst people sans abnormal individuals.

If you do this, you'll either (a) go with the desires people actually have on this theory, or (b) with the desires it is normal for people to have. If you go for (b), then you basically have a version of Natural Law. Which is fine.

If you go for (a), then I think you will run into the problem that sometimes when your brother or sister needs you most, the very situation that causes their need can make you not have a desire to have a special bond with them.
