Science and Christian Ethical Thinking (AQA A-Level Religious Studies): Revision Notes
Science and Christian Ethical Thinking
Introduction: the neuroscience challenge
Neuroscience poses a significant challenge to religious belief by suggesting that all human experiences, including religious ones, can be explained through brain activity. The human brain contains approximately 100 billion neurons, which function as data processing units.
The challenge from neuroscience centres on the claim that the self or soul is simply neural activity connected to a living body. When the body dies, neural activity ceases, suggesting that the self or soul also dies.
Three Major Problems for Christian Belief:
This neuroscientific view creates fundamental challenges:
- There would be no self morally responsible to God
- There would be no self capable of having a personal relationship with God
- There would be no self that could survive death
However, the theory of Dual Aspect Monism offers a potential response to these challenges. This view proposes that the self is a combination of mental and physical aspects united in one substance. According to this perspective, it is not possible to reduce the human mind to purely physical descriptions, suggesting that the relationship between mind and brain is more complex than simple reductionism allows.
Understanding science and its relationship to ethics
What is science?
Science is not simply a body of knowledge but rather a method of understanding the world. This method is based on reason and evidence, involving systematic observation, experimentation, and testing.
Science's Moral Neutrality
Crucially, science itself is morally neutral. As a form of investigation, science does not make moral judgements. Moral questions only arise when scientific discoveries lead to technologies that impact people's lives, other species, or the environment. The science itself is neither good nor bad; it is the application of scientific knowledge that raises ethical concerns.
The Christian tradition of engaging with science
Christians have a long history of using science to improve human life. Medicine was a feature of Christian communities long before modern scientific advances.
Historical Example: Medieval Christian Medicine
Medieval monasteries played a leading role in caring for the sick, demonstrating early Christian engagement with medical knowledge. This established a pattern where Christians have frequently been at the forefront of developments in:
- Medicine and healthcare
- Transport and communications
- Technologies serving the vulnerable
The Christian tradition has emphasised using scientific knowledge to care for the vulnerable, grounded in theological understanding of human responsibility.
Most Christians maintain that God organised the world for the benefit of humankind from its creation. This belief supports the view that it is right to understand the natural world and develop ways of improving the human condition. However, this raises a fundamental question: how far is the natural order an expression of God's will, and how much can or should it be changed using science and technology?
Key ethical approaches in Christian responses to science
Christians have developed different approaches to address the ethical challenges posed by scientific advances. Understanding these approaches is essential for evaluating Christian responses to modern scientific issues.
Natural Law approach
The Natural Law approach seeks to preserve life because of the basic human urge to live. This perspective considers what is natural as a guide to what is right. The Roman Catholic Church typically adopts this approach when addressing medical ethics.
Applying Natural Law: Persistent Vegetative States
When considering extreme medical conditions such as persistent vegetative states, a Natural Law approach would generally favour preserving life using available medical technology, because the preservation of life aligns with natural human inclinations.
This demonstrates how Natural Law prioritises the fundamental drive toward life preservation over other considerations.
Utilitarian approach
A utilitarian approach seeks to maximise happiness and minimise pain. This consequentialist perspective evaluates actions based on their outcomes rather than fixed rules.
In medical contexts, utilitarianism could lead to different conclusions depending on the circumstances. It might support euthanasia if this would minimise suffering, or it might justify using every available technology to prolong life if this produces the greatest overall happiness. Utilitarianism might also consider the distribution of medical resources, questioning whether expensive treatment for one patient is justified when the same resources could provide simpler treatments benefiting many patients.
Biblical approach: "What would Jesus do?"
Some Christians, particularly Protestant evangelicals, approach modern ethical issues by drawing parallels with situations described in the New Testament. They effectively ask, "What would Jesus do?" in a given situation.
The Challenge of Biblical Application
However, this approach faces a significant challenge: medical technology did not exist in Jesus' time, so there is no direct biblical guidance on many modern issues. The Bible cannot tell us what Jesus' attitudes to contemporary medical treatments, genetic modification, or life-extension technologies might have been.
This creates a danger that people may read into biblical narratives the answers they wish to find, rather than discovering genuine biblical guidance.
The challenge of applying biblical authority
If the Bible is considered the ultimate authority on Christian behaviour, modern medical technology presents a particular problem. Since such technology was not available two thousand years ago, there is no straightforward way to read the Bible and find clear answers to contemporary ethical questions.
Major moral issues posed by science
Modern medicine
Modern medicine has transformed human capabilities, offering potential cures for many illnesses and the ability to prolong life significantly. However, these advances create difficult ethical questions:
- When is it right to turn off life-support machines and allow someone to die?
- Should expensive treatment be provided for one patient when the same resources could benefit many through simpler treatments?
- Would procedures like brain transplants be ethically acceptable?
- Should people in persistent vegetative states be kept alive using medical technology, or is death a natural feature that should be accepted?
Joseph Fletcher's Situation Ethics
Joseph Fletcher, who developed Situation Ethics, argued that Christianity needs to embrace new technologies when they can improve people's lives. He believed this might require abandoning rule-based ethics such as Natural Moral Law, which he saw as obstacles to developing Christian ethical thinking in response to new challenges.
Exam tip: Be prepared to evaluate different Christian approaches to specific medical scenarios, explaining both why Christians might support or oppose particular uses of medical technology.
Genetic modification
Genetic modification raises profound questions about the extent to which humans should alter what believers might consider God's creation. Key issues include:
- Would genetic modification to make people stronger or healthier be acceptable?
- Are there limits to what humankind should do to change the natural world?
- Should genetic manipulation be used to adapt humans for space exploration or different environments?
- Could Christians justify genetic changes that allow humans to survive in high-gravity or low-oxygen situations?
Fletcher's Situation Ethics perspective suggests that genetic modification should be considered where it would improve the human condition. He recognised that space exploration might become necessary to relieve population pressure on Earth's environment and resources, potentially requiring genetic manipulation to allow humans to live in different environments.
Life extension and immortality
Science has developed the potential to merge human biology with robotic systems and potentially upload human minds into computer environments that could be subjectively immortal. This raises questions that touch the boundary between science and religion:
- Would Christians be justified in seeking indefinite life extension through technological means?
- What would life extension imply for Christian beliefs about life after death?
- If technological immortality becomes possible, how does this relate to traditional Christian teachings about eternal life?
Science and evolutionary ethics
The challenge of "survival of the fittest"
Modern interpretations of natural selection raise fundamental ethical questions for both secular and religious ethics. Herbert Spencer (1820-1903) coined the phrase "survival of the fittest" to summarise Darwin's theory of evolution.
Some thinkers developed this concept into an ethical view: if the weakest in society receive help and survive to reproduce, the species as a whole might weaken. According to this logic, the strong should be encouraged and the weak eliminated to secure a better future.
The challenge to Christian compassion
This evolutionary ethical perspective could view Christian ethics, with its emphasis on compassion for the vulnerable, as potentially weakening the human species. This represents a direct challenge to fundamental Christian values.
Discussion Question: Evolution vs. Christian Compassion
Does evolution's demonstration that only the fittest survive undermine Christianity's moral commitment to caring for the weakest members of society?
This question highlights the fundamental tension between evolutionary ethics and Christian values of compassion and care for the vulnerable.
Nietzsche's response
The German philosopher Friedrich Nietzsche addressed these issues in his 1883 work "Also sprach Zarathustra" (Thus Spoke Zarathustra). He challenged people to envision their future in terms of an Übermensch (Superman or Overman) who would represent the next step in evolutionary progress.
While a crude interpretation of this concept contributed to the Nazi holocaust, Nietzsche was actually arguing for new answers to ethical problems in a rapidly changing world. He believed that without adapting ethical thinking, both Christians and atheists would lack adequate responses to the directions science might take humanity.
Key ethical questions raised by evolution
Evolution through natural selection raises several challenging questions for Christian ethics:
- If God's creative plan operates through natural selection, it is based on the systematic failure and death of the majority of members of any species. Can this be compatible with a Christian ethic based on compassion?
- If altruism (acting selflessly for others' benefit) is simply a genetic trait designed to promote one's own species' success, is it just disguised selfishness rather than genuine moral behaviour?
- If everything is built on basic laws of physics and is theoretically predictable, how can Christian ethics be based on personal freedom and moral commitment?
Environmental ethics
Scientific impact on the environment
Scientific advances in agriculture and farming, including genetic modification of crops and animals, have arguably had increasingly negative effects on the world's environment.
Christianity's role in environmental damage relates to certain interpretations of scripture. Some Christians interpret biblical texts as giving humans dominion over the entire environment. This interpretation has contributed significantly to the environmental crisis, as it can be used to justify exploitation of natural resources without concern for long-term consequences.
Dominion vs. Stewardship
Not all Christians accept this interpretation of dominion. Many argue for stewardship rather than exploitation, viewing humans as caretakers of God's creation rather than having unlimited rights to use it as they wish.
This distinction is crucial for understanding different Christian responses to environmental ethics.
The Christian response to environmental crisis
Although many churches have developed environmental policies, there has been little coordinated effort among Christians to make a major impact on environmental issues. This represents an ongoing challenge for Christian ethical thinking in response to scientific developments.
Exam tip: Be able to explain different Christian interpretations of human dominion over creation and how these relate to environmental ethics.
Key Points to Remember:
- Science is a method of understanding based on reason and evidence, not itself a body of knowledge; it is morally neutral
- Christians have historically engaged positively with science, particularly in medicine and care for the sick
- Three main Christian approaches to scientific ethics: Natural Law (preserving life), Utilitarian (maximising happiness), and Biblical (asking "What would Jesus do?")
- Modern medicine, genetic modification, and life extension raise profound ethical questions without clear biblical precedents
- Evolutionary ethics based on "survival of the fittest" can challenge Christian emphasis on compassion for the vulnerable
- Environmental damage has been linked to some interpretations of Christian beliefs about human dominion over creation
- Contemporary Christian ethics must address entirely new issues not faced in biblical times, requiring reasoned justification rather than simple application of ancient texts
