This is the sixth of a series of posts examining Ronald Lindsay’s view on the ethics of embryonic stem cell research as he put forth in a white paper called, Stem Cell Research: An Approach to Bioethics Based on Scientific Naturalism.
Lindsay next deals with the issue of whether embryos are entitled to the same rights as human persons. Even phrasing the question in this way reveals a bias which will influence conclusion. Lindsay starts out assuming that embryos are not human, but only have the capacity to become human.
There are some who believe that embryos deserve the full range of rights provided to human persons and that removing an embryo from that possibility of developing the capacities and properties characteristic of human persons is morally equivalent to killing an adult human.
He “dogmatically†claims to know what makes a human a human. Again, from where did his scientific research give him this knowledge? How does he know this based on metaphysical naturalism? He objects to the view that embryos should be afforded the same moral status as adult human persons. Then, having done so, he claims that “there is no significant moral impediment to embryonic stem cell research.†He holds the view that embryos are to be treated as human persons to be “fundamentally flawed†on the basis of several claims.
First, he argues, it is in tension with accepted scientific understanding of embryonic development. Second, it is based upon a controversial metaphysical position. And, finally, it conflicts with many of our moral judgments and ultimately is unsupported by a credible theory of moral status. Contrary to Lindsay’s claims, present understanding of embryology provides no problem for the view that embryos are human persons. By any objective, scientific standard, the embryo qualifies as a member of the human race. From the moment of conception, the embryo is an individual, distinct from mother, father, and other living things, having her own unique genetic fingerprint. The embryo is living, characterized by metabolism, growth, reaction to stimuli, and reproduction. The embryo is human, carrying DNA with a human genetic signature. Furthermore, regarding his claim that the metaphysical claim that embryos are human persons is controversial, all metaphysical positions are controversial! Lindsay’s own metaphysical position is no less controversial than any other. Given Lindsay’s own commitment to naturalism, one might argue that Lindsay has no access to any real knowledge on morality or whether there are such things as morals.
One of Lindsay’s objections to giving equal moral status to embryos and adult human persons is that the embryo is not an individual. Up until gastrulation, the embryo may undergo a process called “twinningâ€, in which two separate human persons may be produced. He implies from this process, that an embryo cannot be a human person because then one would have two of the same person. What do we make of this claim? First of all, most embryos do not “twin†and so there is only one embryo present. Second, there is no reason to suppose that twinning undermines the claim that there was at least one individual there from the moment of conception. Lindsay states that the claim that “John†is present from the outset “is nothing more than a dogmatic claim masquerading as fact. There is no scientific evidence to establish the presence of a “John.†Lindsay is looking in the wrong place to establish John’s presence. This is more a metaphysical question than a scientific one. Science cannot tell us whether there is a “John†or not. His appeal to science to find John begs the question as science cannot find something which it is not equipped to find.
Lindsay then objects to the claim that the embryo is equivalent to a human person. He argues:
The possibility that an embryo might develop into a human person does not obviate the fact that it has not yet acquired the capacities and properties of a person. An embryo is no more a human person than an acorn is an oak tree. Not only do embryos lack consciousness and awareness, but they do not have experiences of any kind, even of the most rudimentary sort.
Lindsay seems to define human personhood as having “the capacities and properties of a personâ€. Once again, I must ask what scientific study gave him this knowledge. I must also ask what scientific study has determined what the capacities and properties of a person are. C. Wayne Mayhill addresses the acorn-oak tree analogy:
Could it be that comparing embryos, or preborns and adults for that matter, to acorns and oaks is dehumanizing and misleading? After all, when an acorn is stepped on, the forest experiences no moral dilemma. When a “toddler” sapling dies the “mother tree” does not weep. We naturally value oak trees more than acorns. Unfortunately, the comparison encourages us to make the quantum leap of concluding we should value bigger and older people more than smaller and younger ones (specifically, the unborn). But what are our reasons for valuing the oak tree over the acorn? They are not moral or humanitarian, but simply pragmatic… Even if the analogy of the embryo to the acorn were accurate, scientifically speaking an acorn is simply a little oak tree, just as an embryo is a little person. Despite the dehumanizing elements of the acorn-oak analogy, those who understand what an acorn is will realize that, ironically, the analogy serves the opposite purpose for which it is intended… Every oak tree was once an acorn. So it is with the person-a person doesn’t simply come from an embryo or a fetus. A person was an embryo and a fetus.
Lindsay then makes the argument that the location of the embryo within a woman’s uterus is of great consequence. It will not develop unless it is provided with the appropriate conditions. The embryo cannot develop on its own. Furthermore, he claims that in the two possible sources of ESC, spare embryos from IVF procedures, and SCNT (somatic cell nuclear transfer), the embryos are removed from that environment and cannot develop into full human persons due to their present conditions. He seems to think this somehow affects the moral status of the embryo. It seems that Lindsay’s argument proves too much. By the same distorted logic, infants and toddlers should not have moral status. A one week infant is totally dependent on others to reach its “potential†so I guess we have no moral obligation to the infant. I can see no rational distinction between the two cases.
Lindsay next claims that there are unacceptable consequences of the view that an embryo is the moral equivalent to an adult human person. It is stated that between 2/3 and 4/5 of all embryos produced through standard sexual reproduction are spontaneously aborted. If these are human persons, he claims this is a horrible tragedy and a public health crisis. He criticizes those who oppose ESCR for not addressing this crisis. He then reasons that this view would also make IVF (in-vitro fertilization) morally objectionable because extra embryos may be discarded. Finally, he argues that because the debate is primarily over federal funding of ESCR and not whether it should be banned, it is obvious that we do not seriously consider the embryo a human person. At most, Lindsay’s arguments would show inconsistency on the part of opponents of ESCR and do nothing to refute the position they hold. However, most opponents of ESCR would not consider any of these consequences an objection to viewing the embryo as a human person. Certainly, they would be in favor of doing all that is scientifically and medically possible to decrease the number of spontaneous abortions. Lindsay fails to mention that it is felt that most of these miscarriages are due to non-viable embryos/fetuses. They are, in a sense, “sick†and therefore “die†like all humans do. Most opponents of ESCR are also opposed to any form of IVF which discards unwanted embryos and are not in favor of producing more embryos than will be implanted. Most serious opponents of ESCR also are in favor of banning the procedure and consider the issue of federal funding a place to argue for their moral beliefs.
Next, concluding the series.
