Unlike many philosophers who write on biomedical ethics, John
Hardwig is not primarily concerned to test our intuitions about
the limits of normative theories by thought experiments or
problematic borderline cases. Rather, he presses us to accept
the conclusions to which our most firmly held principles commit
us. But these conclusions, if Hardwig is right, turn out to
be quite startling claims about moral duty that would undermine
much of contemporary bioethical theory regarding end-of-life
decisions. On his view, we must face squarely the moral
implications of our present arrangement of healthcare funding
in the United States, where more and more of the financial
responsibility of care is being shifted onto the families of
patients, often with disastrous results. Yet, in the context of this
increasingly unstable arrangement, our chief principle of medical
decisionmaking also holds that their interests are
not morally relevant at all in deciding what should be done
for the patient, and only the patient's wishes
count (insofar as we can determine them). Now Hardwig thinks
that this rule is irrational in the present circumstances, and
that it would make more sense to admit the moral relevance of
the interests of family members, but also that if we do give
appropriate weight to their concerns, we shall be led in some
cases to the conclusion that the patient has a duty to die.
