THE LOCKHART REVIEW
On the use of embryonic stem cells
Australia December 2005
A Commentary By
Dr. Joseph Santamaria
INTRODUCTION
The Lockhart Review Committee released its final report to the Federal
Parliament on its website on December 19, 2005. It revealed that the
Committee has received 1035 submissions to its Inquiry on Embryo Experimentation.
The great majority of the submissions were against the use of embryonic
stem cells as their harvesting involved the destruction of human embryos.
It awakened old memories.
In 1972, in a journal called Interchange, Professor M.A. Jeeves,
a neuroscientist, wrote an article on science and ethics and commented:
Since ethical principles are not logically derivable from scientific
findings, any attempt to elevate science to the level of an ethical
system, which must be believed or accepted, immediately opens itself
to abuse in that it means that particular scientists claim to derive
their ethical beliefs from their science and then set these forward
as the ones that must be accepted by all people.
This can be done in several ways. I draw attention to the submission
of the National Health & Medical Research Council. The Council
encouraged ongoing community debate on the cloning of human embryos
for research purposes and recommends that researchers continue to
have access to excess ART embryos to continue research in these areas.
There is no debate about the ethics of using such embryos for research
purposes but there is a presumption that the community has accepted
this state of affairs, that the ethical debate is no longer an issue.
Professor Alan Trounson opens his article in the Herald-Sun (23/12/2005)
by calmly ignoring the moral status of the Human Zygote formed by
somatic cell nuclear transfer. The Lockhart committee gives no moral
status to the human embryo in the first 14 days after the human zygote
has been formed and therefore its destruction in that period has no
moral significance.
THE ETHICAL DILEMMA
In the fields of Reproductive Technology and Biotechnology generally,
the underlying ethical position of the scientists around the world
is based on Utilitarianism which now is presented in a subtle form.
A very successful tactic of the scientific community is to appeal
through the media, to present victims with severe physical disabilities
who plead for such research to continue as their last chance of any
hope of recovery from their crippling handicaps, even though there
is no scientific evidence that embryonic stem cells can achieve such
an outcome. Compassion becomes the key to ethical behaviour and opposition
to embryo experimentation becomes a mark of insensitivity to human
suffering.
James V. Schall (Crisis October 2005 p.63) has remarked that today's
ethical appeal to compassion as the focus of decision making is a
feature of the modern corruption of the word Justice. This new concept
is an extension of the bewildering demands for social rights that
have penetrated into virtually all fields of human society so that
if embryonic stem cells may improve my state of health, I have a right
to have my wishes fulfilled by the justice system acting out of compassion
for my present state of suffering. But surely the virtue of justice
would extend to the human embryo, to a more fundamental right for
it to exist and to grow and not to be treated as a material commodity
for the good of others. This modern clamour for a host of human rights,
recognized in such documents as anti-discrimination legislation or
a Bill of Rights, lends itself to a vague use of language with no
hierarchy of values that serve both the good of the individual and
the common good of the community. This in turn allows unelected judges
to apply ideological interpretations that impose a new set of community
values or standards that creates a new "morality".
In fact, in its final report, the Lockhart committee adopted this
principle by effectively giving no moral status to the human embryo.
All its extraordinary and far-reaching recommendations flow from the
modern corruption of the concept of justice and the pressures applied
by the scientific lobbies with deep vested interests.
VALUE JUDGMENTS IN SCIENCE
Science can add a great deal to our store of knowledge but it is not
within the scope of its methodology to resolve ethical dilemmas, to
determine or to assume how we should act ethically or morally. In
commenting on scientific findings, scientists often introduce their
own value judgements and reach conclusions or recommendations that
can be validly contested by non-scientists, especially when they reflect
on issues such as human rights, the moral status of members of the
human species, the manipulation of public opinion and the distribution
of public funds for the assertive promise of an advancement in clinical
medicine.
Value judgements reflect the basic beliefs and creed of an individual
and these are not derived solely from empirical studies. They are
influenced by upbringing, philosophical reflection, behavioural preferences,
career pathways, vested interests, and social mores. This applies
to theists and atheists alike. They cannot be tested for validity
by scientific experiments or methodology. The conclusions drawn from
scientific studies are often based (legitimately) on philosophical
principles that provide an independent avenue to the acquisition of
knowledge. However this aspect of scientific publications is open
to distortion and deceit as data can be used selectively or be generated
by flawed methodology to support an underlying ideology or vested
interest of the scientist.
Scientists often adopt the position that only empirical studies can
establish the validity of our perception of reality. They baulk at
the idea that philosophical principles can pose hypotheses or theories
that move beyond the ambit of scientific inquiry. But even in the
speculations of science, in the formulation of hypotheses and commentaries
on empirical data, science employs the principles of philosophy, of
logical analyses and rational thought.
EMBRYONIC STEM CELLS
It is highly doubtful if embryonic stem cells can ever be used in
clinical medicine unless cloning is done using somatic cells of the
patient (somatic cell nuclear transfer). All its claims for the treatment
of any disease process are purely speculative. It is highly doubtful
if such cloning can be done without a large bank of donor human ova
. As the ova will contain the extranuclear DNA of the donors, the
question of the immune rejection of the embryonic cells enters into
the equation of informed consent. There is no doubt that the treatment
of a patient will be at a prohibitive cost. It is known that cell
lines established from such embryonic stem cells tend to undergo genetic
drift or changes as successive populations are generated from the
original cloned cell. It is known that such cells are prone to serious
tumour formation. In the clinical situation, whether it be in clinical
trials or treatment procedures, no such activities can be undertaken
without the fully informed consent of the patient and institutional
ethics committees would be reluctant to approve their use.
These are ethical issues and they are not resolved by the claim of
scientists that all will be well under regulations written into legislation
that allows them to experiment on human embryos, however they are
obtained. It is also a distortion to suggest that those who oppose
experimentation on human embryos are insensitive to the suffering
of those with chronic disabilities who may show some response to stem
cell therapy. The evidence is overwhelmingly in favour of the use
of adult stem cells in such cases but such information is obscured
by the scientific lobbies for the use of ESCs.
The diversion of enormous amounts of public funds into research on
human embryos is being justified on a clinical premise that is unfounded
and a claim that the technology and its products will generate economic
wealth for our nation. This is otherwise accurately known as the "commodification"
of the human embryo and its cell lines and there is nothing to suggest
that human cloning will not become the standard method of creating
human embryos for commercial exploitation.
The review committee has summarily and scandalously dismissed the
ethical questions that have been sharply highlighted in the majority
of the submissions that they have received. Whether the submissions
have arisen from an intuitive concept of human dignity or a clear
understanding of the scientific evidence, the human embryo, however
formed, is a member of the human species, the earliest stage of our
human existence. It deserves the protection of the law and of international
declarations. These opinions constitute a powerful reminder that ours
is a human society that can be degraded by our failure to protect
the weakest of our members.
A CONSCIENCE VOTE BY ELECTED REPRESENTATIVES.
In the light of the weight of the responses received by the Lockhart
Committee, it is a moot point as to what is meant by "their conscience
vote." The Lockhart committee has effectively commodified the
human embryo for the interests of science; it has singularly failed
the nation and has thrown into disrepute the value of so-called expert
committees appointed by governing bodies.
