Pre-implantation genetic diagnosis (PGD) is a medical procedure that enables the selection of embryos for implantation based on genetic characteristics. This technique can be used to screen for certain genetic disorders, chromosomal abnormalities, and sex selection. Although PGD can prevent the birth of children with serious genetic disorders, it also raises several ethical challenges.
One of the ethical challenges raised by PGD is the potential for eugenics. Eugenics is the idea of improving the human race by selecting for desirable traits and eliminating undesirable ones. PGD can be seen as a form of eugenics because it allows parents to choose the genetic traits they want in their children. This raises concerns about the potential for discrimination against people with certain genetic traits, and the societal pressure to conform to a certain standard of genetic perfection. Hank Greely, who argues that PGD raises ethical concerns related to eugenics, discrimination, and societal pressure to conform to certain genetic norms writes, "PGD may be seen as a form of eugenics, raising concerns about the values and ethics of choosing one's children based on certain traits, and the potential for discrimination against people with certain genetic traits" (Greely, 2017, p. 191). Greely also notes the potential for PGD to lead to a homogenization of the gene pool, and questions whether this is a desirable outcome. The Islamic perspective on PGD is that it is acceptable only when used for medical reasons and not for non-medical purposes, such as sex selection or choosing physical traits. According to the Islamic Organization for Medical Sciences, "PGD is permissible when it is used for the prevention of genetic diseases, but not when it is used to select gender or traits" (Islamic Organization for Medical Sciences, 2003, p. 7).
Another ethical challenge raised by PGD is the possibility of creating a "designer baby". This refers to the use of PGD to select traits that are not related to medical conditions, such as physical appearance, intelligence, or athletic ability. The concept of creating a "perfect" child raises concerns about the commodification of children and the devaluation of human diversity. Ruth Chadwick, has written about the potential for PGD to contribute to a "new eugenics", whereby the selection of certain traits becomes more important than the prevention of serious genetic disorders. She writes, "If PGD becomes the norm, it could change what we mean by 'normal' and could contribute to a new eugenics that would be less obviously discriminatory, but no less ethically suspect" (Chadwick, 2013, p. 35). Further the Catholic Church, for example, has expressed concern about the use of PGD for non-medical reasons, such as selecting for physical appearance or intelligence. The Church has stated that "any attempt to produce human beings by artificial means outside the conjugal act is morally unacceptable" (Catechism of the Catholic Church, 1997, §2377). This position reflects the Church's belief that human reproduction should be governed by natural law and not by human design.
Furthermore, there are concerns about the emotional impact of PGD on the children who are born as a result of this technology. Children who are born through PGD may feel pressure to live up to their parents' expectations and may feel that their worth is based on their genetic makeup. This could lead to feelings of inadequacy or low self-esteem. This is supported by Jonathan Glover, who, focuses on the potential psychological effects of PGD on individuals and families. He writes, "The process of PGD involves significant ethical challenges, particularly in terms of the psychological effects on those involved. The pressure to select for certain traits can be overwhelming, and the resulting children may feel that they have been engineered for a particular purpose" (Glover, 2006, p. 79).
Counter-argument:
However, some argue that PGD can actually promote reproductive autonomy and prevent the birth of children with serious genetic disorders. In fact, PGD has been used successfully to prevent the transmission of genetic disorders such as cystic fibrosis and sickle cell anemia. This can have a positive impact on the lives of individuals and families who would otherwise be burdened with caring for a child with a serious medical condition. Peter Singer notes that PGD can be used to prevent the transmission of serious genetic diseases, thereby improving the health of future generations. He writes, "PGD can be a valuable tool for preventing the transmission of genetic diseases, and can improve the health of future generations" (Singer, 2004, p. 64). Singer also suggests that PGD could be used to increase the genetic diversity of the population, which could be beneficial in terms of avoiding inbreeding and promoting resilience to disease. Similarly, Jonathan Glover acknowledges the potential benefits of PGD in preventing serious genetic diseases and disorders. He writes, "PGD can be used to prevent the transmission of serious genetic disorders, which can be a significant benefit for families at risk of passing on these disorders" (Glover, 2006, p. 79).
Another counter-argument is that the potential for eugenics can be mitigated through regulation and oversight. PGD is a highly regulated medical procedure that requires approval from a medical ethics committee. The use of PGD for non-medical reasons, such as selecting for physical appearance or intelligence, is also generally not permitted. This means that the risk of discrimination or societal pressure to conform to a certain standard of genetic perfection is minimized.
Counter-counter argument:
However, despite these safeguards, there is still the potential for PGD to be misused or abused. The regulation of PGD is not foolproof, and there may be cases where parents or doctors use this technology for non-medical reasons. Additionally, the idea of genetic perfection is subjective and can vary depending on cultural, social, and individual perspectives. Therefore, it is difficult to regulate the use of PGD in a way that is completely objective and unbiased. Peter Singer argues that PGD raises concerns related to the selection of certain traits and the potential for discrimination against individuals who do not possess those traits. He writes, "PGD is not merely a tool for preventing disease, but for selecting traits. This raises concerns about discrimination against individuals who do not possess the desirable traits, and about the impact of such selection on society" (Singer, 2004, p. 65). Singer also notes the potential for PGD to contribute to a widening gap between the rich and poor, as wealthy individuals may be more likely to have access to the technology.
In conclusion, pre-implantation genetic diagnosis raises several ethical challenges, including the potential for eugenics and the creation of "designer babies". Both Singer and Glover emphasize the need for careful consideration of the ethical implications of PGD, particularly in terms of the potential for discrimination and the psychological effects on individuals and families. While PGD can prevent the birth of children with serious genetic disorders, it also has the potential to create a society that values genetic perfection over human diversity. While there are arguments in favor of PGD, including the promotion of reproductive autonomy and the prevention of genetic disorders, it is important to consider the potential risks and ethical challenges associated with this technology.

The concept of sanctity of life has been an important ethical principle in religious traditions, particularly in Christianity, Judaism, and Islam. However, some critics argue that this concept has no meaning in twenty-first century medical ethics, as modern medicine has shifted towards a more utilitarian approach that prioritizes autonomy and quality of life over the preservation of life at all costs. While there are certainly weaknesses in the claim that sanctity of life has no meaning in contemporary medical ethics, it is important to consider both the strengths and weaknesses of this argument.
One weakness of the claim that sanctity of life has no meaning in contemporary medical ethics is that it overlooks the ongoing influence of religious traditions on medical ethics. As the philosopher John Haldane notes, "Religious ethics and moral theology continue to play a significant role in shaping medical ethics" (Haldane, 2018, p. 5). While it is true that modern medicine has shifted towards a more utilitarian approach, many medical professionals and patients continue to draw on religious concepts such as sanctity of life in their decision-making.
Furthermore, the concept of sanctity of life can still be seen as relevant in contemporary medical ethics when considering issues such as end-of-life care and euthanasia. As the theologian Nigel Biggar argues, "The concept of sanctity of life has a particular relevance in the context of debates about end-of-life care and assisted dying, where the ethical principles of autonomy and quality of life can come into conflict with the value of preserving human life" (Biggar, 2017, p. 85). In this sense, the concept of sanctity of life can serve as a valuable counterbalance to the utilitarian approach that often dominates contemporary medical ethics.
However, there are also weaknesses in the claim that sanctity of life has meaning in contemporary medical ethics. One major weakness is that the concept is often vague and open to interpretation, which can make it difficult to apply in practical decision-making. As the philosopher Margaret Somerville notes, "The sanctity of life concept has been criticized for being too abstract and difficult to define, making it difficult to apply in concrete situations" (Somerville, 2007, p. 42). This lack of clarity can lead to confusion and disagreement about how to balance the value of human life with other ethical principles such as autonomy and quality of life.
Another weakness of the concept of sanctity of life is that it can be seen as overly restrictive and inflexible, particularly in cases where preserving life may lead to unnecessary suffering. As the philosopher Daniel Sulmasy writes, "The concept of sanctity of life can be criticized for being overly rigid, as it may require us to prolong life even in situations where death would be a natural and peaceful release from suffering" (Sulmasy, 2014, p. 81). In such cases, the emphasis on preserving life at all costs may be seen as incompatible with the ethical principle of avoiding unnecessary harm and suffering. Peter Singer argues, "The notion that human life is sacred just because it is human life is medieval. We need to replace the sanctity-of-life ethic with a quality-of-life ethic" (Singer, 1993, p. 107).
In conclusion, while the claim that the religious concept of sanctity of life has no meaning in twenty-first century medical ethics has weaknesses, it also has some merit. On the one hand, religious traditions continue to play a significant role in shaping medical ethics, and the concept of sanctity of life can still be seen as relevant in certain contexts. On the other hand, the vagueness and inflexibility of the concept can make it difficult to apply in practical decision-making, and it may conflict with other ethical principles such as avoiding unnecessary harm and suffering. Ultimately, it is important to carefully consider the strengths and weaknesses of the concept of sanctity of life in order to make informed ethical decisions in medical contexts. As Jonathan Glover writes, "The idea of the sanctity of life is often taken to be the cornerstone of morality, but this can be problematic because it is not clear what it means or how it should be applied" (Glover, 2012, p. 1).
