Respect for other selves.

Philosophers have mostly advocated that advance directives should bear the same authority, with regard to refusal of life-extending treatment, as a patient's contemporaneous consent or refusal. Such authors typically support this position through a theory of persistent personal identity. I agree that the loss of mental competence does not render someone a moral stranger to their prior goal but argue that equating advance direction with consent is to ignore the capacity of nonpersons to attribute and withhold moral value. A distinction should be drawn between advance directives that seek to pursue deeply held goals and those that express contempt for the mentally incompetent.
