Welcome to Developments in Bioethics (Unit AS 7)
Welcome to your study notes for Developments in Bioethics, a core topic in CCEA AS Unit 7: Foundations of Ethics with Special Reference to Issues in Medical Ethics. Don't worry if medical ethics feels overwhelming at first! We will break down every debate, ethical theory, and medical technology step by step so you can walk into your exam with total confidence.
Exam Snapshot: Unit AS 7 is assessed through a 1 hour 20-minute written examination. It makes up 50% of your AS Level (and 20% of your full A Level). In the exam, you will answer one question from Section A and one question from Section B. Success in this unit requires balancing religious teachings with secular ethical perspectives and applying core ethical theories accurately.
1. What is Bioethics? The Core Foundations
Bioethics is the branch of ethics concerned with moral, social, and legal issues arising from advances in biology and medicine. The term was coined in 1970 by V.R. Potter, who famously described it as a "science of survival"—bridging biological knowledge with human values.
The Fundamental Clash: Sanctity of Life vs Quality of Life
Almost every debate in bioethics comes down to a clash between two central principles:
• The Sanctity of Life Principle (SOLP): This view states that human life is sacred, holy, and belongs entirely to God. Life is a gift from God (the author and giver of life) and has intrinsic value from its very beginning, regardless of its ability, health, or status. The key biblical foundation is Genesis 1:27: "So God created mankind in his own image" (the concept of Imago Dei). Because humans carry the image of God, taking innocent human life violates the Decalogue (Ten Commandments: "You shall not murder").
• The Quality of Life Principle (QOLP): This secular ethical approach argues that the value of human life depends on the presence of certain qualities or conditions, such as the ability to feel pleasure or pain, consciousness, rationality, communication, and personal autonomy. If a life is filled with unbearable suffering or lacks basic cognitive function, it does not possess the same moral value as a flourishing life.
Memory Trick: Think of SOLP as "Who made you" (God gives intrinsic value) and QOLP as "How you experience life" (instrumental value based on well-being and capacities).
Key Takeaway: Traditional religious ethics builds upon the Sanctity of Life (Imago Dei), while modern secular thinkers (such as utilitarians) generally argue from a Quality of Life perspective.
2. The Status of the Embryo & The 14-Day Rule
A central debate in reproductive bioethics is: When does human personhood begin? Different ethical and religious traditions offer distinct answers, which directly shape their views on fertility treatments and embryo research.
Key Views on Embryo Status
• From Conception (Immediate Personhood): This is the traditional Roman Catholic position, supported by organisations like the Anscombe Centre for Bioethics. The moment fertilization occurs, a unique human genetic code is created. At this instant, the embryo is considered a full human person with a soul (ensoulment occurs at conception) and possesses a right to life. Consequently, any destruction of embryos in research or IVF is viewed as the destruction of human life.
• At 14 Days (The Primitive Streak / The Warnock Report 1984): The landmark Warnock Report (1984), chaired by Dame Mary Warnock, established the UK legal framework which was later enacted in the Human Fertilisation and Embryology Act 1990. The report concluded that human embryos could be used for research up to 14 days after fertilisation. Why 14 days?
1. The primitive streak appears around day 14, marking the first sign of the development of the nervous system.
2. Prior to day 14, an embryo can split to form identical twins or recombine. After day 14, individual identity is biologically fixed. Therefore, 14 days marks the threshold of individual biological human life.
• Islamic Perspectives on Ensoulment: In Islamic Law (Sharia), the preservation of life and the preservation of lineage are fundamental principles. Islamic jurisprudence distinguishes between biological life and ensoulment (when the soul enters the body). Many scholars cite 120 days (or in some traditions, 40 days) as the point of ensoulment. While the pre-ensouled embryo is respected and cannot be discarded casually, research or medical intervention prior to ensoulment may be tolerated if it serves a clear therapeutic benefit to human health.
Key Takeaway: Roman Catholicism views the embryo as a person from conception; the UK legal standard (Warnock Report) sets the line at 14 days with the primitive streak; Islamic tradition links personhood to the progressive stages leading to ensoulment (often at 120 or 40 days).
3. Assisted Reproductive Technologies (ART)
Modern medicine provides several ways to assist couples struggling with infertility. You need to understand the mechanics and the moral questions surrounding each technique.
1. In-Vitro Fertilisation (IVF)
In-Vitro Fertilisation is a procedure where an egg is surgically removed from the ovaries and fertilised by sperm outside the body in a laboratory dish ("in vitro" means "in glass"). Once fertilised, one or two healthy embryos are transferred to the woman's womb.
The Ethical Dilemma: IVF often involves creating "spare" or surplus embryos. Those not implanted may be frozen, donated for scientific research, or eventually destroyed. For Sanctity of Life advocates (like the Roman Catholic Church), the destruction of surplus embryos is morally unacceptable. Secular utilitarians, however, view IVF positively because it relieves the suffering of childlessness and creates happiness.
Pre-implantation Genetic Diagnosis (PGD): Often used alongside IVF, PGD involves testing embryonic cells for specific genetic diseases before implantation. While it prevents hereditary illnesses, critics argue it can lead to "designer babies" and discrimination against disabled individuals.
2. Artificial Insemination (AIH vs AID)
• AIH (Artificial Insemination by Husband): Sperm from the husband is mechanically introduced into the wife's reproductive tract. This is widely accepted by many Christian denominations and Islamic law because it operates strictly within the marital union.
• AID (Artificial Insemination by Donor): Sperm from a third-party donor is used. This causes significant ethical concern for many religious traditions:
- Catholic & Orthodox views: Rejects AID because it introduces a third party into the sacred one-flesh marital union and separates procreation from sexual union.
- Islamic view: Strictly forbids AID. Sharia requires that pregnancy must only occur between legally married partners to protect clear biological lineage.
3. GIFT (Gamete Intra-Fallopian Transfer)
In GIFT, eggs and sperm (gametes) are collected and placed directly into the woman's fallopian tube before fertilisation happens. Because fertilisation takes place inside the woman's body (in vivo) and does not involve creating spare embryos in a lab, some Christians who reject IVF find GIFT morally acceptable.
4. Surrogacy
Surrogacy is an arrangement where a woman carries a pregnancy for intended parents. CCEA requires you to distinguish between two types:
• Partial (Traditional) Surrogacy: The surrogate mother provides her own egg, which is fertilised by the intended father's sperm (often via artificial insemination). She is the genetic mother.
• Total (Gestational) Surrogacy: The surrogate carries an embryo created from the intended parents' egg and sperm (or donor gametes). She has no genetic link to the child.
Ethical Objections:
- Risk of commercial exploitation and commodification of children (treating a baby like a commercial product).
- Emotional trauma for the surrogate mother upon relinquishing the child.
- Sharia law forbids surrogacy because it violates lineage and involves a third party carrying a child outside a valid marriage contract.
Key Takeaway: Treatments confined strictly to husband and wife (AIH, GIFT) receive broader ethical acceptance than methods involving third parties (AID, Surrogacy) or the creation and destruction of excess embryos (IVF).
4. Key Thinkers and Perspectives
To achieve high marks in AS 7, you must refer directly to key scholars, institutions, and ethical frameworks.
1. Brendan McCarthy (Anglican Perspective)
Brendan McCarthy, a prominent Church of England advisor on bioethics, argues that Christian ethics must balance compassion with core theological principles:
• God as the Author and Giver of Life: Human life is a gift, not a human possession.
• Justice for the Vulnerable: Society must protect those who cannot speak for themselves, including the unborn and the sick.
• Stewardship over Dominion: Humans are stewards entrusted to care for life, not masters with absolute authority to manipulate human nature as they see fit.
2. The Anscombe Centre for Bioethics (Roman Catholic Perspective)
The Anscombe Centre for Bioethics (based in Oxford) is a leading Catholic bioethics institute. Drawing on Catholic moral theology and Natural Law, the Anscombe Centre advocates that:
• Human life begins at the single-cell stage of conception and has full moral status.
• Medical technology must serve the natural dignity of the human person and marital intimacy, rather than replace natural procreation.
• Practices that destroy embryos (IVF with surplus embryos, embryonic stem cell extraction) or separate procreation from marriage (AID, surrogacy) are intrinsically wrong.
3. Peter Singer (Secular Preference Utilitarianism)
Peter Singer strongly challenges the traditional Sanctity of Life doctrine, calling it outdated and guilty of "speciesism" (bias toward human beings simply because of their biological species). Singer argues:
• Quality of Life over Sanctity of Life: Moral status depends on capacities like consciousness, self-awareness, and the ability to feel pleasure or pain.
• Embryo Status: An early human embryo has no brain, nervous system, or capacity for consciousness. Therefore, it lacks personhood and has no moral interests.
• Controversial Comparison: Singer argues that conscious, feeling animals (like adult chimpanzees or pigs) possess greater personhood and moral status than an early human embryo or anencephalic infant lacking consciousness.
4. Islamic Jurisprudence (Sharia) Summary
• Preservation of Lineage and Life: Islam encourages seeking medical cures for infertility, but only within the boundaries of a valid marriage.
• Allowed: AIH and IVF using only the husband's sperm and wife's egg, implanted in the wife's womb.
• Forbidden: AID, egg donation, and all forms of surrogacy, as they disrupt family lineage and introduce an outside party into the marital covenant.
Key Takeaway: McCarthy stresses Christian stewardship and justice; the Anscombe Centre defends the moral status of the embryo from conception; Singer advocates secular utilitarian quality of life; Islamic ethics demands the strict preservation of lineage.
5. Common Pitfalls & How to Avoid Them
Make sure you take note of these common errors identified in CCEA Chief Examiner reports:
• Pitfall 1: One-Sided Answers: Students often write essays containing only religious arguments (e.g., Roman Catholic views) while ignoring secular counterarguments. Fix: Always balance religious views with secular philosophical perspectives like Peter Singer's utilitarianism.
• Pitfall 2: Vague Biblical References: Writing "the Bible says life is special" will limit your marks. Fix: Quote and unpack specific concepts, such as Genesis 1:27, the concept of Imago Dei, or the prohibition of killing in the Decalogue.
• Pitfall 3: Lack of Precise Terminology: Avoid generic descriptions like "test-tube babies." Fix: Use accurate terms like In-Vitro Fertilisation (IVF), Pre-implantation Genetic Diagnosis (PGD), AIH, AID, and the Primitive Streak.
• Pitfall 4: Mixing AS 7 with A2 7: Do not waste time writing complex A2 Meta-Ethics (e.g., Emotivism or Intuitionism). Keep your ethical analysis focused on the normative foundations required for AS (Natural Law, Utilitarianism, Sanctity vs. Quality of Life).
6. Quick Revision Summary
Key Dates & Reports:
• 1970: V.R. Potter coins the term Bioethics ("science of survival").
• 1984: The Warnock Report recommends the 14-day limit for human embryo research (based on the appearance of the primitive streak).
• 1990: Human Fertilisation and Embryology Act enshrines the 14-day rule into UK law.
Key Ethical Frameworks to Compare:
• Roman Catholic / Anscombe Centre: Sanctity of Life from Conception; Imago Dei; Natural Law; procreation must remain unsevered from marital intercourse.
• Anglican (McCarthy): Stewardship, God as life-giver, justice and protection for the vulnerable.
• Secular Utilitarian (Singer): Quality of Life; reject speciesism; early embryos lack personhood and consciousness.
• Islamic Law (Sharia): Preservation of life and lineage; fertility treatment permitted only between legally married spouses without third-party involvement.
