Baby born with anencephaly to please jesus?

[Anomalocaris]

Someone in a persistent vegetative state resulting from evident excessive brain tissue destruction, and thus manifestly lacking the mechanism to even theoretically regain faculty for more than reflexive action, is considered human only out of courtesy to the relatives.

So your first statement that an ability to respond is now being modified to include the destruction of brain tissue? I'm confused, how was any brain tissue destroyed in a baby born with anencephaly? Defining a human person isn't too easy is it?

Defining a human person is very easy, provided one is making the definition with definite clarity of purpose. It only become not so much difficult as futile, when one attempts to define human person with an eye towards satisfying multiple non-overlapping sets of often contradictory purposes.

Ability to respond, or reasonable expectation of eventually acquiring the ability to response, to stimulus in a more than simply reflexive way is necessary, but not sufficient, component of what makes the product of human reproduction a person. Having the appropriate brain tissues is in turn a necessary, but insufficient condition for the ability to so respond, or to eventually acquire the ability to so respond.

So brain tissue is the foundation. No brain tissue, no possibility of personhood.
