Conservative
opponents of embryonic stem cell research frequently argue that supporters of
the medical research focus on scientific technicalities at the expense of
morality. Eric Cohen, editor of the
neoconservative journal The New Atlantis,
puts the complaint succinctly:
[c]ritics of the Bush policy should
also address its supporters on their own terms, and rather than argue only
about scientific adequacy, they should consider seriously the moral dilemma the
policy seeks to address (Cohen 2006).
Cohen seems to
suggest that the critics of the Bush policy have not addressed the ethical
issues surrounding embryonic stem cell research. Yet, as Cohen surely knows, numerous
authoritative bodies have explained the moral justifications for the research,
and most Americans share these views.
Cohen and other conservative bioethicists often appear to regard those
who do not share their ethical views as lacking in moral seriousness, a
position that is itself unserious in its estimation of those who have
legitimate disagreements.
Embryonic stem
cell research is morally permissible because, although embryos deserve respect,
they are not morally equivalent to human beings. This moral argument was described in the 1994
�Report of the Human Embryo Research Panel� (HERP) for the National Institutes
of Health (NIH) as the pluralistic approach: Rather than focus on a single
feature to determine when embryos are considered morally equivalent to full
persons, the pluralistic approach holds that �protectability is not an
all-or-nothing matter but results from a being�s increasing possession of
qualities that make respecting it more compelling� (NIH 1994). As human life
develops, it begins to take on added moral worth and gains added respect and
rights; arguing that a sperm or a collection of cells in a Petri dish are
morally equivalent to a living person, or even a developing fetus, fails to
recognize the emergent character of human life and personhood.
The HERP
report contrasts this pluralistic approach with attempts to find a single
criterion that clearly establishes moral status, such as genetic identity or
development potential. These attempts
inevitably �create paradoxes in logic and run counter to many widely accepted
practices,� such as contraception and in vitro fertilization, problems which do
not plague the pluralistic approach. The
pluralistic approach acknowledges that while an embryo does not entail the same
legal and moral protections as a person, it is still valued and protected;
embryo destructive research may be conducted, but it must be �well-justified
research.�
Scientific
bodies, presidential advisory councils, philosophers and theologians of all
faiths, and the general public all support regulated embryonic stem cell
research based on the lesser moral status of the embryo. As the National Bioethics Advisory Commission
(NBAC) stated in �Ethical Issues in Human Stem Cell Research�,
we have found substantial agreement
among individuals with diverse perspectives that although the human embryo and
fetus deserve respect as forms of human life, the scientific and clinical
benefits of stem cell research should not be foregone (NBAC 1999, 106).
Both the American Association for the
Advancement of Science (AAAS 1999) and the National Academy of Science (Committee on Guidelines for Human Embryonic Stem Cell
Research 2005) have concluded that respect for human embryos does not
prohibit embryonic stem cell research, and no presidential council, including
the current one, has determined that the embryo�s moral status precludes
research on it.
The American
people also support the nuanced view that embryos possess lesser moral status
than persons. Recent polls show that
anywhere from 57% to 67% of Americans support stem cell research, and the same
Genetics and Public Policy Center study that found that 67% of people support
the research also determined that only 30% of the respondents believe the
embryo has no moral status (Pew Research Center 2005). Furthermore, the study found that, of those
who do accord human embryos the highest moral status, one-third still support
human embryonic stem cell research. People do have respect for embryos, which
is why they want to ensure that research using them proceeds carefully,
ethically and with clear regulations and oversight.
The moral
argument of stem cell supporters explains their predilection with scientific
technicalities and regulation; the morality of the research depends on these
crucial details. Engaging in the serious
moral debate at hand means examining the specifics of research procedures, the
current state of technology and potential success rates to ensure the research
is justified. Research guidelines like
those put forward by the National Academies, which require institutional review
boards and oversight committees, help ensure that research is �well-justified�
enough to ethically allow the destruction of embryos. Ethical standards for stem cell research will
need to change along with technology, scientific knowledge and societal
attitudes. To ensure ethics keep pace
with these changes, and to maintain transparency and public engagement in
embryonic stem cell research policies and practices, the National Academies has
recently created a committee to monitor the field, updating and adjusting
research guidelines as needed.
We are
confident, however, that opponents of embryonic stem cell research will
continue to depreciate such efforts by the scientific community, and therefore
the views of most Americans that they reflect, as lacking in moral
seriousness. Diversity of opinion is
welcome, but assertions that the proponents of embryo research have failed to
address the moral issues are simply false.
It is time for these critics to engage in the sort of serious
introspection they demand of others.
