Significant Moral Value (Kevin Doran)

(A comment on the Opinion of the Irish Council for Bioethics on Embryo Research: Sunday Business Post: 27/04/08)

 

The idea of the Irish Council for Bioethics granting "significant moral value" to human embryos would be amusing, if it were not so arrogant.

 

Last week's opinion published by the council said: "On consideration of the various arguments relating to the moral status of the embryo, the council adopts a gradualist position, granting significant moral value, rather than full moral status, to human embryos. The moral value they are seen to possess is based on recognition of their potential to develop into persons, as well as the value they derive from representing human life in its earliest stages."

 

In initial discussions 18 months ago, I indicated that Catholics had some difficulty with the idea of "assigning rights" to the embryo, which was the terminology the council was proposing at the time. My problem is that this might be taken to imply a reference to civil or discretionary rights. The Catholic perspective is that the rights of the embryo derive from its nature and, in that sense, are human rights, the kind that would be described in some documents as self-evident. Such rights are not assigned or granted (as the report now suggests). 

 

The obligation to respect life begins at the point when individual human life begins -- or even when there is a reasonable possibility that it may have begun. The council rejects the argument that the embryo is a person, on the grounds that personhood implies characteristic personal activity (or sentience). But human or personal activity is the result of being a person, not the cause of it. The council seems to be falling into the common trap of confusing "person" and personality." The embryo is a person, but it doesn't have personality.

 

The opinion said that the council believes that "the moral value of human embryos that will otherwise remain frozen or be destroyed needs to be balanced against the moral value of human welfare, which is likely to increase with advances in medical science that ameliorate quality of life. While accepting the value of human life demands that we hold significant respect for embryos, it also demands that we consider our obligations to care for humankind more generally. The Council would, therefore, consider embryonic stem cell research to be acceptable in certain contexts."

 

While the council said it did not think that the creation of embryos specifically for research was currently justified or represented a proportional response while "supernumerary IVF embryos" existed, it reserved the right to re-evalute the balance between ethical concerns and the value to society of such research if IVF processes become more efficient, with a resulting drop in the number of "supernumerary embryos" available for research, or if the therapeutic potential of somatic cell nuclear transfer (SCNT) was borne out by research.

 

The underlying ethos of the council's opinion is predominantly utilitarian. In effect it says: "We would prefer not to destroy embryos, but if it seems to serve a useful purpose, we will." It is easier, of course, to make this kind of judgment if one sees oneself as granting moral value to the embryo.

 

Similarly, the opinion that embryos should not be generated specifically for research, is subject to a utilitarian caveat. The council effectively says: "If supplies of embryos from IVF dry up, then we might reconsider this." In other words, the council has no principled objection.

 

But then the bioethics council goes on to argue against the undue instrumentalisation of human life. Is there a principle anywhere in all of this?

 

It is good that the council recognises cloned embryos as having the same value as so-called "supernumerary embryos". Unfortunately, this is a rather limited value.

 

There are a number of important issues around the use of terminology.

 

The report said the Council "supports the carefully regulated use of supernumerary IVF embryos -- that are otherwise destined to be destroyed -- for the purposes of embryonic stem cell research aimed at alleviating human suffering. The decision to donate supernumerary embryos for research should be voluntary, free from any form of coercion and made under the strict conditions of informed consent". The designation of certain embryos as "surplus" or "supernumerary" tends to imply that they are of less value, or that they are less entitled to be protected. It suggests that, by using them for research, they are given some value, whereas otherwise they would die uselessly. This view also flows from the underlying utilitarian ethos of the opinion. Objectively speaking, the value of so-called "supernumerary embryos" is exactly the same as that of any other embryo. They are only "destined" to die because of the decisions that people have made about them.

 

In the opinion, a distinction is made between "reproductive cloning", for the purposes of transmitting life to a new human being, and "therapeutic cloning", which would be for the purpose of obtaining embryos for biomedical research. In reality, whatever its ultimate purpose and whatever terminology people may choose to employ, human cloning is always reproductive, in that the immediate result of cloning is the generation of a human being. It is never "therapeutic", in the generally understood sense of the term, because it never contributes to the health or well-being of the embryo who is the subject of research. Any distinction between "therapeutic" and "reproductive" cloning is unscientific and spurious, and appears designed to facilitate the use of embryos for research.

 

On the topic of animal-human chimeras, the report said: "If the creation of embryos for research were deemed to be acceptable at some point in the future, the council would have no principled objection to the creation of human-animal hybrid cell lines, which would obviate concerns relating to coercion and exploitation of women".

 

An embryo may be cloned using an animal ovum (egg), where the animal nucleus is removed and replaced with the nucleus of a human cell. As the ICB notes in the document, this does not mean that all of the animal DNA has been removed. Some small -- but potentially significant -- amount of animal DNA is left in the mitochondria of the cell, and eventually becomes part of the new organism. It is not clear what this DNA will do, or how it will affect the development of the embryo. The ICB seems to justify this on the basis that the embryo will not, in any case be allowed to develop. But once again the council dodges the question as to what exactly this embryo is.

 

Crucially, the opinion of the Irish Council for Bioethics does not reflect the outcome of its public consultation. According to the council's own analysis of the consultation, respondents were fairly well balanced between men and women and there were more respondents under 45 than over.

 

A huge majority of these were opposed to research using embryonic stem cells, the generation of embryos specifically for research or the generation of hybrid human-animal embryos.

 

There are risks in determining ethics by public consultation, because popular opinion doesn't always reflect the truth. But it does seem odd that the opinion of the council is so much at variance with the public perception of this issue.

 

The one question to which there seemed to be no very clear answer was who should fund embryonic stem-cell research, if it were allowed in Ireland. Presumably this is because the vast majority of those who might be expected to meet these costs believe such research shouldn't be permitted.
