3.1.2 - Animals in scientific procedures and cloning
Animal experiments promise medical knowledge, while cloning may aid agriculture or conservation; both can also impose pain, failed pregnancies and death on sentient creatures. Dolly the sheep and the 3Rs of replacement, reduction and refinement make the conflict concrete. You will apply Aquinas' natural law, Fletcher's agape and Aristotle's virtue ethics, explaining and evaluating when claimed benefits can justify animal harm.
The Animal-Science Issue
AQA's wording is not asking for a general essay on whether animals matter. It asks how three ethical theories apply to two connected practices: using animals in scientific procedures and cloning animals. The key is to ask what each theory treats as morally decisive.
Animal experimentation
The use of non-human animals in experiments for medical or scientific progress.
In the UK context, animal research is legally regulated through the Animals (Scientific Procedures) Act 1986. A scientific procedure is not just ordinary handling of an animal. It refers to research activity that may cause a protected animal pain, suffering, distress or lasting harm above a defined threshold. The Home Office licensing system and the 3Rs give the background moral pressure:
| 3R | Basic meaning | Ethical pressure it creates |
|---|---|---|
| Replacement | Use a scientifically satisfactory non-animal method wherever possible. | If an alternative exists, animal use is harder to justify. |
| Reduction | Use the minimum number of animals consistent with the objective. | Scientific benefit does not automatically justify unlimited use. |
| Refinement | Reduce pain, suffering, distress or lasting harm as far as possible. | Even permitted research must be judged by how it treats the animals involved. |
Cloning means producing a genetically identical copy of biological material. In animal cloning, the most famous example is Dolly the sheep, produced from an adult cell using somatic cell nuclear transfer. That example matters ethically because cloning is not only "copying an animal"; it can involve embryos, surrogate mothers, failed pregnancies, animal health risks and questions about whether animal reproduction is being treated as a human-controlled technique.
| Issue | What makes it morally serious? |
|---|---|
| Animals in scientific procedures | Possible human or veterinary benefit is set against animal suffering, captivity, death, and the danger of treating animals as mere instruments. |
| Animal cloning | Possible research, agricultural or conservation benefit is set against embryo loss, surrogate risk, abnormal development, reduced genetic diversity and control over reproduction. |
Natural Moral Law
Natural moral law, with reference to Aquinas, is a deontological approach because moral judgement is grounded in right reason and objective goods, not simply in whatever outcome happens to follow. For Aquinas, practical reason directs human beings to do and pursue good and avoid evil. Standard A-level summaries often express this through primary precepts such as preserving life, reproduction, education, ordered society and worship of God.
| Scholar/source card | Content |
|---|---|
| Aquinas, Summa Theologiae | Natural law is connected with practical reason, human nature and objective goods. |
| Decision rule | Ask whether the action fits right reason and the purposes built into human and natural life. |
| Animal-science pressure | Animals are not normally treated as equal rational agents, but human use of animals still has to be rational, ordered and directed to genuine goods rather than cruelty or vanity. |
Applied to animals in scientific procedures, natural moral law may allow some animal research if it serves serious human goods, especially preservation of life, health and knowledge. For example, research aimed at treating disease could be judged more defensible than research serving trivial curiosity or commercial convenience. But natural law also asks whether the use is proportionate and whether suffering is needlessly caused. If the same knowledge can be gained without animal harm, a natural-law argument has less reason to permit animal procedures.
The application is not simply "animals are below humans, so anything is allowed." A stronger natural-law answer says:
- Human beings may use non-human animals for rationally ordered goods.
- The intended good must be serious, such as life, health or necessary knowledge.
- The method must not express cruelty, disorder or contempt for creation.
- Avoidable suffering counts against the action because reason should order human power responsibly.
Applied to animal cloning, natural moral law is more suspicious. Cloning may appear to detach reproduction from its natural order and turn living creatures into products of technical control. If cloning involves high embryo loss, suffering in surrogate animals or abnormal offspring, the practice can look contrary to rational care for living things. A limited natural-law defence is possible only if the cloning serves a serious good, uses proportionate means, and respects the natural goods involved as far as possible.
Natural moral law can permit animal use for serious rational goods, but it resists needless suffering, trivial purposes and cloning that treats reproduction as mere manufacture.
Situation Ethics
Situation ethics, with reference to Fletcher, is teleological. It judges actions by the loving outcome in the concrete situation rather than by fixed rules treated as absolute in every case. Fletcher's key term is agape: self-giving love that seeks the good of others.
| Scholar/source card | Content |
|---|---|
| Joseph Fletcher, Situation Ethics: The New Morality | Moral decisions should be made by applying agape in the situation. |
| Decision rule | Ask what action will bring about the most loving result for those affected. |
| Animal-science pressure | Human benefit, animal suffering, scientific reliability, available alternatives and the seriousness of the need all matter because the situation matters. |
Applied to animals in scientific procedures, situation ethics is likely to be more flexible than strict natural law. It may approve animal research if it is the most loving way to prevent serious suffering, such as research into a disease where no adequate alternative exists. The 3Rs fit this kind of reasoning because they help ask whether animal harm is really necessary and whether a more loving option is available.
But situation ethics does not automatically approve every experiment. A procedure done for a trivial reason, with poor scientific design, avoidable pain or a non-animal alternative, is hard to describe as agapeic. Fletcher's personalism puts persons at the centre, so human welfare may carry particular weight, but a loving decision should still be alert to the suffering of sentient animals and the character of the community that permits that suffering.
Applied to animal cloning, situation ethics asks a practical and outcome-focused question: would this particular cloning project produce the most loving result? A project to create disease models for life-saving treatment may be easier to defend than cloning for novelty, prestige or cosmetic commercial gain. However, if cloning predictably involves many failed embryos, suffering surrogate mothers or unhealthy offspring, then the loving outcome may be too uncertain or too costly.
| Situation-ethics test | Application to animal science |
|---|---|
| Who is affected? | Patients, scientists, animals, surrogate animals, future animals and wider society. |
| What is the likely benefit? | Medical knowledge, treatment, veterinary benefit, conservation or food/agricultural gain. |
| What is the likely harm? | Pain, distress, death, failed pregnancies, abnormal development or public loss of trust. |
| Is there a more loving alternative? | Non-animal methods, fewer animals, refined methods or not doing the project. |
Virtue Ethics
Virtue ethics, with reference to Aristotle, is character based. It asks what a practically wise and virtuous person would choose, and what kind of character is expressed by the action. The question is not only "what rule applies?" or "what result follows?" It is also "what would compassion, justice, temperance and practical wisdom require here?"
| Scholar/source card | Content |
|---|---|
| Aristotle, Nicomachean Ethics | Moral virtue is formed by habit and involves trained choice; intellectual virtue includes the wisdom needed to judge well. |
| Key term | Phronesis means practical wisdom: judging what virtue requires in a concrete situation. |
| Animal-science pressure | A good scientist or society should show compassion, intellectual honesty, humility, justice and restraint, not cruelty, carelessness, pride or greed. |
Applied to animals in scientific procedures, virtue ethics focuses on the agent and the practice. A virtuous researcher would not use animals casually, hide suffering, overstate benefits or ignore alternatives. A virtuous community would value compassion and honesty while also recognising that medicine and knowledge can serve human and animal flourishing.
This means virtue ethics can support some carefully regulated research, especially where it shows practical wisdom: serious purpose, transparent design, humane care and willingness to replace animal use when possible. Yet it criticises procedures shaped by vices:
| Virtue or vice | How it applies |
|---|---|
| Compassion | Takes animal suffering seriously rather than treating it as invisible. |
| Justice | Asks whether vulnerable creatures are being exploited for weak reasons. |
| Temperance | Resists excess, vanity, profit-driven pressure or unnecessary repetition. |
| Intellectual honesty | Requires good evidence that the procedure is needed and scientifically valid. |
| Hubris | A vice where human technical power becomes arrogant control over living things. |
Applied to animal cloning, virtue ethics asks whether cloning expresses wise stewardship of knowledge or a vice such as domination. Cloning for serious research or protection of endangered genetic lines might be defended if done with humility, care and realistic assessment of welfare risks. Cloning for spectacle, commercial prestige or mass replication of valued animals may suggest intemperance and failure to respect living creatures as more than products.
Virtue ethics judges animal procedures and cloning by the character they express: wise, compassionate and honest use of science is different from callous, excessive or arrogant control.
Comparison In Two Cases
The most exam-useful comparison is not "which theory likes animals most?" It is: what does each theory ask first when judging the same practice?
| Theory | First question | Animals in scientific procedures | Animal cloning |
|---|---|---|---|
| Natural moral law | Does this fit right reason and objective goods? | May permit serious, proportionate research for life, health or knowledge; rejects needless cruelty or avoidable harm. | Suspicious if cloning distorts natural reproduction or causes serious welfare harms; possible defence only for serious goods and proportionate means. |
| Situation ethics | What action best expresses agape in this situation? | May permit research where it is the most loving available way to reduce suffering; rejects trivial or avoidably harmful procedures. | Assesses the concrete project: loving benefit may justify it, but high suffering or uncertain benefit weakens it. |
| Virtue ethics | What would a practically wise and virtuous person do? | Supports humane, honest, restrained research; condemns callousness, poor design, secrecy or excess. | Asks whether cloning shows wisdom and care, or hubris, commodification and lack of restraint. |
Argument chain
| Step | Applied ethics move |
|---|---|
| Claim | The same animal-science practice can receive different judgements because the theories use different moral tests. |
| Reason | Natural law prioritises objective goods and right reason; situation ethics prioritises loving outcomes; virtue ethics prioritises character and practical wisdom. |
| Example | A painful animal procedure for a serious disease might be permitted by situation ethics because of agape, by natural law if proportionate to preserving life, and by virtue ethics if it shows compassion, honesty and restraint. |
| Implication | Evaluation should compare the quality of each moral test, not merely list three conclusions. |
This also helps avoid a common weak answer. It is too thin to write: "Natural law says no because it is unnatural, situation ethics says yes because it is loving, and virtue ethics says be virtuous." A developed answer explains why the theory reaches that judgement and what evidence could change it.
AO1 To AO2 Bridge And Paragraph Use
For AO1, you need to apply each theory accurately to both animal scientific procedures and cloning. For AO2, you need to judge how persuasive that application is.
| Accurate AO1 point | AO2 move it supports |
|---|---|
| Natural moral law can justify animal use for serious goods such as life, health and knowledge. | This gives clear limits, but critics may say it remains too human-centred and can understate animal suffering. |
| Natural moral law may object to cloning as a disruption of natural reproduction. | This is coherent within a teleological view of nature, but it may look too quick if cloning reduces disease or protects life. |
| Situation ethics weighs the concrete outcome through agape. | This is flexible and compassionate, but "the most loving outcome" may be hard to calculate when benefits are uncertain and animals suffer now. |
| Virtue ethics asks what a wise and compassionate person or community would do. | This avoids mechanical rule-following, but it may give less precise guidance when virtues pull in different directions. |
A thin paragraph says:
Natural law is against cloning because it is unnatural, situation ethics supports animal testing if it is loving, and virtue ethics says people should be compassionate.
That has the right labels, but it is too shallow. It does not show how the theories actually reason.
A stronger paragraph would say:
The three theories judge animal cloning by different moral tests. Natural moral law asks whether cloning fits right reason and the natural goods connected with life and reproduction; it may therefore object when cloning treats animal reproduction as manufacture or causes avoidable suffering in surrogate animals and offspring. Situation ethics asks whether a particular cloning project produces the most loving outcome, so it could defend cloning for serious medical research but reject it for trivial or commercial purposes. Virtue ethics shifts the focus to character: a practically wise community would show compassion, humility and intellectual honesty, so it would avoid cloning that expresses hubris or treats animals merely as products. This suggests that the strongest evaluation is not simply "for" or "against" cloning, but whether the purpose, method and welfare costs can be morally justified.
Why this improves:
| Improvement | Effect |
|---|---|
| Applies all three AQA theories. | Meets the exact specification wording. |
| Separates the two issues from wider animal ethics. | Stays focused on animal procedures and cloning. |
| Uses specialist vocabulary: right reason, agape, phronesis, natural goods and hubris. | Shows developed AO1 understanding. |
| Ends with a qualified judgement. | Builds AO2 rather than adding a vague opinion. |
Useful synoptic links later:
- Animals as food and intensive farming: another non-human life/death application, but not the same issue.
- Blood sports: useful contrast because the purpose is usually entertainment rather than scientific or medical benefit.
- Animals as a source of organs for transplants: another case where serious human benefit is weighed against animal harm.
