Cloning and Other New Reproductive Technologies
An Extreme Case: "A furious debate about the morality of artificial insemination has erupted over the case of a 62-year-old Frenchwoman, who revealed yesterday her brother was the biological father of her baby." (The National Post, June 21, 2001, A13)
As always, new technologies raise new ethical problems (or new variations on old ones). Tonight, we're going to consider the moral status of a number of New Reproductive Technologies. We'll focus primarily on cloning and genetic engineering.****************************************
A New Legal Framework: The Assisted Human Reproduction Act
Draft legislation presented to the Standing Committee on Health, May 3, 2001It prohibits or controls a broad range of forms of assisted reproduction
Basic Prohibitionsassisted reproduction procedure = "any controlled activity undertaken for the purpose of facilitating human reproduction"
"3. (1) No person shall knowinglyPaid Surrogacy
(a) create or participate in the creation of a human clone ...
(b) alter the genome of a cell of a human being or in vitro embryo such that the alteration is capable of being transmitted to its descendants;
(c) maintain an embryo outside the body of a woman after the fourteenth day of its development ...
(f) transplant a sperm, ovum, embryo or foetus of an animal into a human being;...
(h) perform any procedure ... for the purpose of ensuring ... that an embryo will be of a particular sex..."
" 'surrogate mother' means a female person who carries an embryo or foetus derived from the genes of a donor with the intention of surrendering the child at birth to the donor or another person."Sale of Reproductive Materials"4. (1) No person shall pay any consideration to a female person to become a surrogate mother..."
"5. (1) No person shall purchase or offer to purchase sperm or ova from a donor...In-Vitro Fertilization
(2) No person shall (a) purchase ... or advertise for purchase, an in vitro embryo or any part of one ..."
IVFChimeras- 'in glass' fertilizationUnder the AHR Act, IVF would become a controlled activity, i.e., it may only be done if you have a licence
- ova and sperm are collected (from the would-be parents or donors) and combined in a laboratory
- if fertilization occurs, the fertilized eggs are allowed to briefly develop and then either implanted in the would-be mother (or a surrogate) or stored for later attemptsLicences are to be granted by the Minister of Health
"9. (1) No person shall, except under the authority of a licence ... create a chimera for any purpose including research."Remibursement for Expenseschimera = animal/human hybrid embryo or foetus
E.g., for sperm donation, surrogate motherhoodPunishmentOnly permissible under a licence
For engaging in a prohibited activity: fines up to $500,000 and sentences up to 10 years***********************************For improperly engaging in a controlled activity: fines up to $250,000 and sentences up to five years
Why pass all these regulations?
A Practical Reason: Part of the justification given for this law is the need to protect people's health and safety. Many of these technologies are still developing and so some techniques are not well tested. Furthermore, even when these techniques are tried and tested, they are generally only safely applied by someone who has been adequately trained in the use of these techniques.A Moral Reason: Many of these technologies are viewed as being immoral on the grounds that they threaten human dignity.
Dignity
*************************What we're going to look at this evening is the moral reason just mentioned. Some strong claims are made above about what is and isn't consistent with human dignity. We need to consider whether these claims are correct."Every one of the prohibitions we propose, such as human cloning, is on that list of prohibitions because it's inconsistent with human dignity." (Alan Rock, Minister of Health, Comments before the Standing Committee on Health, May 3, 2001)The intent of the legislation is "to draw a line in the sand with respect to some practices that are simply unacceptable, because they're not consistent with human dignity, such as cloning a person and creating animal-human hybrids, beings that reflect both animal and human elements. Those are unacceptable, because they're just not consistent with human dignity." (Alan Rock, Minister of Health, Comments before the Standing Committee on Health, May 3, 2001)
From the Preamble to the AHR Act: "Whereas the parliament of Canada ... recognizes the importance or preserving and protecting ... the integrity of the human genome."
From the AHR Act: "16. (1) The Minister may take, or order any person to take, all reasonable measures that the minister, on reasonable grounds, considers necessary to prevent, reduce or mitigate ... any harm to human dignity..."
Human Cloning
Human cloning is usually presented as being clearly morally wrong. But is this so?Gregory Pence argues it isn't.Who's right?
2. Worries about the moral staus of clones
"many popular ideas about cloned humans are not in the world of real ideas." (133)
3. Worries about the motivation of those who want to have themselves
cloned
The reason needn't always be vanity: what if one member of a couple is a carrier for a serious genetically produced illness?
Pence, in fact, goes beyond a simple defence of the moral acceptability of some cases of human cloning. He also offers a defence of the practice of genetic engineering.
Genetic Engineering
Our improved understanding of genetics promises to make 'designer children' possible, either through selective breeding or actual modification of genes.Two Common Mistakes to Avoid:Pence thinks this is a good idea: "we are obliged to improve the genetic health of future generations and ... [genetic engineering] is one tool that humanity has to do so." (140)The AHR Act effectively bans this practice.
Does it do so for a good moral reason?
1. Thinking of genes as guaranteeing particular traits.Positiive vs. Negative Genetic EngineeringDon't forget the role of environment.2. Thinking of genes as operating in isolation, e.g., a gene for mathematical ability, a gene for athletic ability and so on.Genes typically work in combination.
It may help to differentiate between negative genetic engineering (which involves correcting or avoiding 'defects') and positive genetic engineering (which involves making 'improvements').***************************************'Negative' Genetic Engineering
1. Terminating 'Problem' Fetuses'Positive' Genetic EngineeringProblem: Familiar worries about abortion2. Avoiding Dangerous Genetic Combinations3. Correcting Defects
Problem: (i) Defining Defects - blindness, nearsightedeness, less than 20/20 vision, merely normal(ii) Predicting far-reaching effects - e.g., some 'defects' confer advantages in certain combinations
E.g., sickle cell anemia is a disease with a genetic cause, but the same 'faulty' gene can also confer a resistance to malariaThis is an old idea coupled with a new way of pursuing it"[I]f we are to keep our flock at the highest pitch of excellence, there should be as many unions of the best of both sexes, and as few of the inferior as possible, and ... only the offspring of the better unions should be kept ..." (from Plato's Republic)Some Possible Objedtions to PGE(1) 'it's unnatural'Are these objections compelling reasons for banning PGE?(2) Who will it be available to?
i.e., will it only be available to the rich?(3) Will it create hierarchies amongst kinds of people?e.g., Gattaca(4) It 'commodifies' people.i.e., it requires us to think of humans as collections of good or bad properties, not as intrinsically valuable individualsHow about for banning GE in general?
A Side Issue: Genetic Information
Another way in which the science of genetics raises ethical issues concerns not genetic engineering, but the use we might make of the information genetics reveals about us. As we acquire better and better knowledge of the significiance of our genetic makeup, it becomes possible to detect predispositions to particular conditions.********************************Some Issues:
(1) Genetic Privacy - How much do others have a right to know about you?Does your employer have a right to know if you have a strong tendency to develop some debilitating condition?(2) How much do we want to know about ourselves?What about your health insurance provider?
Suppose tests reveal you have a high probability of developing an incurable, fatal disease. Would you want to know?(3) Genetic Fatalism - Even though our genetic makeup often only indicates a tendency to develop certain conditions, is there a danger that the information they reveal will turn out to be a self-fulfilling prophecy?Consider the search for the so-called 'criminal gene'. Is there a danger that those who possess the gene will be marginalized and so made more likely to become criminals?
Groupwork Question: Should human cloning be banned, as the AHR Act suggests?
