James Peterson
Thank you
to Brent Waters, Jennifer Derryberry, Ron Cole Turner, Garrett Evangelical
Theological Seminary and all the others involved in calling together this
colloquy. And to my colleagues and the audience who have already been so rich
with insights this afternoon. I appreciate the chance to work with you. It
seems to me that most of the moral life is more a question of will than of
discernment. The right thing to do is often clear, we just do not want to see
it or hesitate to do it. The question before us however may be about as much of
a true dilemma as life gives us. It seems to be a clear conflict of life with
life. I only wade into it because it needs to be done. In my brief paper
tonight I will think openly with you, call it as I see it, as clearly as I can.
If by your questions and comments you help me to see where I should change my
perception, I will be grateful. It is a good thing to be delivered from a false
opinion. So, in advance, thanks for the help. What would our Lord have us to do
concerning stem cells? Notice, in keeping with my assignment, I am addressing
what Christians should do, yet in pursuing that question many of the arguments
that I will be raising would be hearable outside a Christian worldview. I am
not aware of any debate about whether it is moral to use stem cells to help
people. The problem is where the stem cells come from. If stem cells could be
obtained from inessential cells of an adult, we could have a perfect tissue
match for the person being treated with no risk of rejection and no moral
question. Such stem cells would possibly save countless lives from paralysis,
Alzheimer's, Parkinson's, Tay Sachs, and other debilitating, even deadly,
diseases. To find a way to do so would be a kind, fruitful, and indeed
thrilling expression of love for those neighbors. That is well worth pursuing.
It may some day be possible, but it is not now and it will not be easy to reach
if we do. While most nucleated cells have all the instructions for a complete
human body, an adult cell has formed into the most effective shape for doing a
specialized task. A tiny fraction of its DNA is guiding the cell s work. The
information is there to make anything in the body, but the DNA and the rest of
the cell have been structurally configured for a particular task. To reform the
DNA into the unshaped potential of an original stem cell is a physically
wrenching task. Some labs have held out hope that someday we will be able to do
it without damaging the information, but in the meantime, and it may be a very
long time, hundreds of thousands of people are struggling and many are dying
who might well be helped by stem cells. Stem cells are available now from the
death of human embryos. There is the question before us. Should we obtain
potentially life giving stem cells from the death of embryos?
There is
no problem with sacrificing human tissue to save human beings, but is the
embryo more than just tissue? If the embryo is a fellow human being, we should
not kill one person to save another. Human beings are simply not available to
cut into parts, no matter how useful. But is the embryo a fellow human being, a
person, a soul, one of us? News accounts of the stem cell debate have often
expressed surprise that many individuals who have worked actively against
abortion have been willing to accept the taking apart of human embryos to obtain
stem cells. That some pro life activists would reject one and accept the other
is rooted in their understanding of what the embryo is.
Is the
embryo a fellow human being? This is not a question that we can leave aside. I
would like to, but it keeps coming back. For research, pre implantation genetic
diagnosis selection, and a myriad of other present and coming techniques the
status of the embryo will be central to whether the intervention should be
welcomed or not. For example if people want to bring together many embryos so
that they can then select the best one or two to implant and discard the rest,
is that seeking the best genetic start for their children, mass murder, or
something else? The question will not be resolved simply by executive orders or
legislation. In my book Genetic Turning Points: The Ethics of Human Genetic
Intervention, the fifth chapter has room to carefully walk through and
bibliographically track the arguments for when we should recognize that a
person is present. Now there will just be time briefly to introduce and begin
to test some of the most widely given reasons for protecting human embryos as
people.
It is
fitting while meeting at a Methodist Seminary to appeal to the Wesleyan
Quadrilateral. Christians have long sought to know Gods will by listening to
scripture, tradition, the direct experience of God, and thoughtful reason.
Different streams within the varied Christian tradition have emphasized one of
these sources over another. The Reformation was rooted in sola scriptura, but
this was never scripture alone. It was rather scripture first, interpreted in
the light of tradition, reason, and experience. So with that in mind, let us
begin by searching the scriptures.
For
Islam, the Koran simply states that a person is present beginning at forty days
after fertilization. The Christian tradition has no such clear statement. Texts
such as Psalm 139:13 are often quoted. It reads, You knit me together in my
mothers womb. The metaphor of knitting conveys God's intimate involvement in
the psalmist's life from the beginning. However, it does not say when that form
in the womb became a human being. God is intimately involved in the formation
of the body that will be the psalmist. That does not tell us when the
developing body is the psalmist. Trying indirectly to extrapolate the timing of
human presence from this text is reading in affirmations that are not present.
Jeremiah
1:5 is often quoted, Before you were in the womb I knew you, before you were
born I set you apart. However, the text is not about human embryology or even
about humanity at all. It is about the surety of what God plans. God has called
Jeremiah to a particular vocation and has been planning this task even before
Jeremiah was in the womb to call to it. There is nothing in the text that
designates when Jeremiah became a living human being. If the point of the text
was instruction about Jeremiahs existence, it would indicate that he was alive
in some realm before being in the womb. Again the quote reads Before you were
in the womb, I knew you. Pre existence is not the point anymore than for
Ephesians 1:4 which states that God chose us in Him before the creation of the
world. The texts are marveling at God s knowledge and choice, not human
existence before time. God knows what is in even the secret place of the womb
(Job 31:15). Embryos are in Gods presence as is all the rest of life. We are
responsible for how we treat them, but when precisely they become persons is
not taught in these A relevant theme that we do have from Christian scriptures
is that followers of Jesus Christ should love their neighbors. Jesus describes
this in Luke 10 as a concern and action for others that reaches out to whomever
one can help. Responsibility, nurture, service, are at the fore. The question
before us remains however that granted we should love our neighbor and that we
know our neighbors who are dying from disease, when is there a neighbor in the
womb to love? Scripture directs us to extend our love to all our neighbors, but
does not specifically tell us when there is a neighbor there. We should
exercise hospitality, but does that include for every sperm or egg? To every
conceptus? The call to love our neighbor does not define the threshold of when
there is a neighbor present to love. We could turn to tradition, the wisdom of
our brothers and sisters in the faith who have lived before us. For much of
church history the dominant view has been that there is not an ensouled body
until there is a body to ensoul. That a body was fully present to be a person
was recognized at formation, forty days into the pregnancy when the basic
organs are present and mainly growth in size remains. John Connery traces this
historic consensus in Abortion: The Development of the Roman Catholic
Perspective, published by Loyola University Press. Following that logic now
with our current knowledge would lead us to about twenty eight days post
fertilization as the time to recognize that a neighbor is present.
We could
turn to our experience of Gods leading. George Annas appeals to a common moral
intuition with the following story. If a fire broke out in a fertility lab and
there was only time to save a two month old baby there in a basinet or a rack
with seven embryos, most people would save the baby without hesitation. Yet
carrying out the test tube rack instead, could have saved seven people, if
indeed each embryo was a person. Thankfully that is not the usual choice that
we face. But if Annas is correct about what we would do, what is guiding our
choice? Could it be that we make a clear distinction between an embryo as
potentially a person and a later point in development as a person actually
present?
Can
reason helps us sort this out? It is often claimed that human development is
such a continuum that no point along it can be marked as to when a human being
has begun. Hence a human being must be present from fertilization. The irony of
this argument is that it is still citing a point at which a person first
becomes present. All of the genes that an individual has were already present
in the egg and sperm that would meet. It is bringing them together in one place
that is seen as the crucial threshold. So by this view there is a threshold
condition for the presence of a person. That then raises the question of why
mark the gathering of the genes for a unique individual as the crucial
transition? Yes, the single microscopic fertilized cell is alive, human (since
from humans), and genetically individual, but then these three attributes apply
to some of the skin cells that we regularly loose in daily life without regret.
Others
have seen the threshold at successful implantation about 6 9 days after
fertilization, because the embryo s chance of birth increases from not
likely (roughly 1 in 3) to likely, or at 14 days when it finally becomes clear
whether there will be one or more individuals since identical twins spring from
one embryo at up to 14 days. For those who think a soul is assigned at
conception, the reality of twinning would mean that either some embryos that
will not survive are soulless from the beginning or some embryos carry two
souls until they split. There could not be a simple one soul to one embryo
correspondence from fertilization.
Maybe the
status of the fertilized cell could be found in the potential to grow into a
live born baby. That is an amazing and important potential, but the egg and
sperm had that potential too. We could qualify the argument that the fertilized
cell does not need another cells input, but it does need millions of cells in
the placenta and nurturing womb to survive and develop. For that matter,
potential means not yet, if ever, not that what has potential has already
become or is guaranteed to become what it has the potential to be. An acorn is
a potential oak tree, which may or may not become an actual oak tree. Now there
is an involved metaphysical argument made by some that the potential of an
embryo is only unfolded over time, hence fully present at fertilization, but
this ignores the formative role of the environment in the womb and beyond.
Genes do not determine all the physical characteristics of an individual, let
alone who the person will be as a person. A set of genes does not a person
make. Think of identical twins with identical genes who yet become and remain
unique persons.
Where each side claims justification from the same concern is in burden of
proof. One side argues that we should not take a chance on ending a human
embryo s life because a person might be present. If there is any chance that a
person may be present, that possibility should receive every protection.
Proponents of using embryos appeal to the burden of proof as well. They say
that we know there are undeniably people dying of Parkinsons, Alzheimers, Tay
Sachs, and other diseases. Their lives may one day be saved by embryo stem
cells. How can we let these people that are unmistakably people, die to protect
an embryo that even if implanted may or may not turn out to someday become a
person? We should not kill people to benefit others, but we should also not let
people die to protect only human tissue such as sperm or ova, even though such
gametes do have great potential. Has the connection of one sperm and one egg
together now made present a human being, who as a human being, should of course
not be sacrificed? Notice each side sees the burden of proof argument as
favoring its conclusion. For both sides, these decisions are a matter of life
and death for many people.
A
variation of the burden of proof argument is that if any developing human life
is not nurtured, we will slide down a slippery slope into the horrific
slaughter perpetrated by the Nazis. This concern refers both to a conceptual
slippery slope that once it is acceptable to kill one human life there is no
longer a clear prohibition to refrain from killing many, and a social slippery
slope that even if there is a good reason to stop abortion at an early stage of
pregnancy, the societal momentum of allowing early abortion will be such that
we will not stop any abortion. Such has indeed been the experience of the
United States since Roe v. Wade. Abortion is now allowed up to the time of
birth and there are prominent ethicists who currently argue for infanticide.
The slippery slope argument concludes that human beings need protection
beginning at some clear early threshold or they will eventually not be
protected at all. Slippery slope concerns are well worth considering. They are
compelling to the degree that there is a slippery slope and the end to which it
leads is abhorred.
Even if
one concluded that an embryo was not a person yet, the embryo could still as a
human embryo warrant more respect and care than mere tissue. The embryo is
potentially associated with a human person in the future. Would proper care for
an embryo be parallel to how we treat a human body after someone has died? Of
course after death, no person is then present in the body, but we still treat
the body with great respect because it was associated with a person. An embryo
hopefully will be associated with a person. Bodies that may become persons and
bodies that were persons are both hallowed by their association with persons,
one potential, the other past. They should hence be treated respectfully but
not the same as bodies that are persons. As a last resort, a body that is no
longer a person can be respectfully used for organ transplantation or in
dissection to teach physicians how to better help bodies that are persons.
Nothing less would be appropriate because the body was associated with a
person. Could the human embryo, worth great respect because of its potential
future association with a person, be used as a last resort to save realized
persons as well? If so, such would not authorize being used for lesser reasons.
Such status would protect embryos, but not claim that the embryo is yet a
person, having the full status of a person. There would still be good reason to
protect embryos, just not to the degree that we would if they were people.
Embryos would be available for the last resort saving of the lives of actual
people, but not for flippant destruction as merely tissue. This respect for
embryonic human life would be substantial but not at the near absolute level
that we recognize for human beings. The question before us this evening will
not go away. We have to address it. Hopefully what has just been covered will
help us to focus on what most still needs our attention to think it through.
