TEACHER’S GUIDE When we say that we believe something, a theory, a story, or body of doctrine we generally mean that we accept it as true. We may even be prepared to use it as a guide to living and act on it although we may lack conclusive evidence that it is in fact true. We all live much of the time by our beliefs, and there are relatively few matters on which we would claim to have certain knowledge. When we talk about knowledge we usually take it for granted that we have grounds or evidence for what we know. In the case of belief the situation can be very different. Many beliefs are not amenable to the same kind of testing as for example scientific hypotheses, and cannot be verified or falsified by the same kinds of evidence. This lack of certainty does not worry us very much where everyday matters are concerned. Some of our beliefs are concerned with fairly ordinary even trivial things. I believe it will rain today so I will take my umbrella. I believe that the latest James Bond movie is the best one I’ve seen. Other beliefs are much more serious and are often acquired, nurtured and developed over many years. This can be the case with a person’s political views or their beliefs about topics and issues that interest them and that they have come to care about deeply. Other kinds of beliefs which people hold are often referred to as ultimate, transcendent, or metaphysical beliefs because their truth or falsity cannot be established by any kind of empirical evidence. These include religious beliefs about the nature, origins and destiny of human beings, their place and significance in the universe; about good and evil and how we should lead our lives; about the existence or non-existence of God. In the eighteenth and nineteenth centuries beliefs such as these encountered significant opposition. Until then, for most people in Britain and throughout Europe, Christianity had provided the basis of their beliefs and values. It told them everything they needed to know about the meaning and purpose of life. The challenge came from two directions. First, scientific discovery and scientific methods began to undermine religious belief. The universe as revealed by science appeared to be governed by natural laws and to be subject to natural forces. Even human life seemed to be explicable in terms of a random process of natural evolution. Second, and perhaps more seriously, secular belief systems emerged which repudiated the supernatural in favour of critical reason. The most powerful of these was Marxism which influenced countless revolutions and, until recently, drove a political wedge between east and west. Humanism, which lies at the heart of Marxist theory, if not all of its practice, places great store on modern science and the scientific method of inquiry as the basis for its view of the world and human nature. Consequently, religious believers find themselves faced with challenges which seem to consist of a mixture of scientific, humanist and marxist argument. These materials deal specifically with Science and Belief. They introduce the challenges which scientific discovery and scientific method raises for religious belief and discuss some of the ways in which Christians in particular have responded. Science and Belief is one of three options within the unit called ‘Nature of Belief’. The three options are: Existence of God Science and Belief Belief and Action. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 3 Each of these options at Intermediate 1 has a clear progression route to their equivalent options at Intermediate 2, and each of the options at Intermediate 2 has a natural progression to the three options within the unit at Higher level called Critiques and Challenges. The Nature of Belief unit whose option is Science and Belief has three key issues: 1. 2. 3. How do we come to know things, dealing with the different ways in which we acquire knowledge about the world; How the universe began, which looks at scientific and religious theories and stories about the origins of the universe; and How did life come about, which considers the different interpretations surrounding ideas about creation and evolution? Students should be encouraged to identify the issues and explain why they present a challenge for religious believers. Analysis of the issues involves distinguishing and explaining both the challenges and responses. Although the citing of sources is not essential, students should be encouraged to make use of them in order to enhance the quality of their understanding. For the purposes of evaluation it is important that all students are given the opportunity to respond to questions that require discussion of both sides of an issue. For summative assessment purposes, however, students at Intermediate 1 level will be required to express an opinion and justify it by giving at least two reasons. In general students should have opportunities to: demonstrate understanding of certain issues of religious belief analyse the issues in terms of challenges and responses evaluate by discussing both sides of an issue justify their conclusions. Teachers will have their own strategies and preferred ways of organising learning. A recommendation to include variety, however, is an important one given that students will inevitably have different learning styles. Students should be encouraged to make use of their own life experiences when exploring and reflecting on issues, and to seek views from a wide range of sources including books, video material, and from recognised specialists in the areas being studied. Opportunities to talk through particular challenges and responses in order to tease out their meaning and significance will be important. Also important will be class and group discussion so that through dialogue, students can learn from others and begin to formulate their own opinions. Familiarity with key texts and passages will enable students to demonstrate an appropriate level of understanding in relation to both challenges and responses, and to support their own conclusions. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 4 Learning strategies will therefore take a number of forms such as: Gathering information and viewpoints from books, video, CD-ROM Student presentation Teacher presentation Class and group discussion Role play Direct teaching. Organising teaching groups The following advice is suggested for teachers/lecturers who might be considering teaching more than one level in the same class i.e. Nature of Belief Intermediate 1 and 2, or Intermediate 2 and Christianity: Critiques and Challenges. Nature of Belief (Int 1 and 2) The content is the same for both levels. It is suggested that differentiation should take place in one of two ways. Students might be given the same or very similar tasks and activities and their work would then be assessed against the performance criteria. Differentiation would be reflected in the length of the response: restricted or extended responses respectively. Alternatively, the tasks themselves might be differentiated. This applies particularly to outcome 3 where Intermediate 1 students are required simply to ‘express a clear personal opinion’ on the chosen issue, while Intermediate 2 students must ‘discuss both sides of a given issue’. Nature of Belief (Int 2) and Christianity: Critiques and Challenges (H) In the content for each level, there are three options which have a close correspondence with each other: Nature of Belief Christianity: Critiques and Challenges Existence of God Science and Belief Belief and Action Secular Humanism Science Marxism Generally speaking there is extended content in the options at Higher, but most of the ideas and issues at Intermediate 2 appear in the equivalent Higher option. It is suggested that students at both levels should be doing communal work at the beginning of the unit and perhaps might be given the same or very similar formative assessments. Clearly, summative assessment of the units at each level would be different, and this reflects the difference in the nature and challenge of the material at each level.

STUDENT’S GUIDE These materials are intended to help you study the challenges to religious belief raised by scientific development and scientific methods and to explore the various responses. You will be expected to explain these challenges and responses and to say what you think about them. You will become familiar with some key texts, passages and commentators within both Science and Christianity. These will help you to understand better the challenges and responses and to support your own views and conclusions. The main issues and areas to be covered are: How do we come to ‘know’ things? Scientific method and religious beliefs. How did the universe begin? Genesis story and Big Bang theory. How did life come about? Evolution and creation. You will need to be able to: describe what the issue is about explain why the issue presents a challenge to religious believers explain clearly the challenge and a relevant response to the challenge discuss both sides of an issue you are given reach a personal conclusion on the issue and give reasons which support it. You should try to refer to sources as often as you can, especially where this helps to show your understanding of a viewpoint or issue. You are encouraged to use direct quotations if you can but there are other useful ways of referring to sources: By naming the title of the source and/or where appropriate, the author By paraphrasing the source so that you use your own words in order to give an accurate account of what is said By a combination of these methods.

Over the last two hundred years religion and science have had an uneasy relationship. They have been seen as poles apart in terms of the method they use and the assumptions they make about how the world should be investigated. Science has been seen as concentrating on observation and experiment and being concerned with the demand for evidence and proof. Religion, on the other hand, has been seen to rest mainly on ‘revelation’ and as being about commitment and faith. Its beliefs cannot be proved using the methods of science. As a result the answers which science gives to questions such as, How did the universe begin? and How did life come about? are seen as much more believable than those offered by religion. Some would argue that the success of science in the twentieth century has been as a direct result of the methods it uses. But is there such a thing as a specifically scientific method? And if so what is it? The scientific method The scientific method is sometimes summed up in the phrase, ‘Only Hippos Eat Vultures’ - observation, hypothesis, experiment, verification. This experimental method is generally thought to have been invented in the seventeenth century and explained first in the writings of Francis Bacon. He was himself an enthusiastic scientist and sought to justify the new methods and assumptions so that science could progress on to greater discoveries. His passion for experiment is said to have resulted in his own death after he contracted a chill. He is said to have got out of his carriage in the depth of winter to carry out an experiment with snow as a means of preserving meat! This scientific method relies on collecting evidence using our senses and tries to draw conclusions based on a number of observations. You make an observation or perform an operation and note the consequences. If the same observation or event is repeatedly followed by the same consequence, you can draw the conclusion that this reflects the way the world is. For example, if you throw a switch on the wall and a light comes on it could be caused by the switch or it could be just a coincidence. If you do the same a second time and the light comes on again, you may well suspect that it was the switch that caused the light to go on. A third, a fourth and a fifth time and you may be pretty sure you are right. This was the scientific method formulated by Francis Bacon and for about 300 years afterwards it was the way most scientists believed they worked. The scientific worldview The roots of the scientific view of the world go back at least to the eighteenth century. Until then, for most people in Britain and throughout Western Europe, Christianity provided the basis of their beliefs and values. It told them everything they needed to know about the meaning and purpose of life. It was the Church that marked and gave meaning to the great moments in their lives. It welcomed their newly born into the community through baptism, blessed their marriages and comforted and reassured them in death. A significant proportion of people gave themselves up completely to religion and became monks and nuns. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 9 The main points of the modern scientific worldview as it developed during the course of the eighteenth and nineteenth centuries are: In contrast to the medieval universe which was created and continually watched over by God, the scientific universe was impersonal and governed by regular natural laws. The universe was now regarded, at least in principle, as completely understandable by the human mind. A knowledge of physics, mathematics and of scientific method was all that was required. There was no need to bring in God. Other aspects of human nature such as the emotional, aesthetic, ethical, and imaginative were generally regarded as irrelevant for an objective understanding of the world. Science replaced religion as the dominant intellectual authority. It was science not the church that people began to look to for information about what the world and the universe was really like. Human reason and scientific observation replaced theological doctrine and the Bible as the principal means for understanding the universe. The freedom of individuals to make up their own minds about what they believed was now strongly emphasised. As a result religious beliefs and religious institutions, which some thought had interfered with people’s right to independence and individual self-expression, became much less important. The effects on religious belief The main effect of scientific discovery and the scientific method was to undermine religious belief. First there was the realisation that it was the earth and not the sun which moved in the Heavens and that the Earth, and therefore humankind, was not after all the centre of the universe. The universe itself was seen to be far vaster than anyone had previously imagined. Moreover, the universe as revealed by science seemed to be an impersonal one, governed by natural laws and understandable in terms of Physics and Mathematics. Even people appeared to be the result of a random and impersonal process of evolution. All this seemed to make the need for God somewhat unnecessary. As people began to accept a scientific view of the world which looked for explanations in terms of regular natural laws, belief in religion was seriously undermined. The scientific methods employed by science were perhaps even more of a challenge to religious belief than scientific knowledge itself. As we have seen in order to establish what is ‘true’ in the scientific realm it was essential to observe, to investigate, carry out experiments, and draw conclusions. Everything was open to question. In other words, for something to be counted as true or factual there had to be evidence available to support it. The problem was that the evidence for many fundamental religious beliefs seemed to be lacking. What sort of evidence could possibly be gathered to support the belief in the resurrection, for example? RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 10 Moreover the process of observing and gathering evidence seemed to many people to be an entirely reasonable way of acquiring knowledge about the world. Religious beliefs, however, appeared not to be subject to that process. They were not amenable to the same kinds of testing and experiment as scientific theories. As a result they began to lose much of their force and credibility. ‘Raisings from the dead, miraculous healings and exorcisms, a divine-human savior, a virgin birth, manna from heaven, wine from water, water from rocks, partings of seas - all appeared increasingly improbable to the modern mind.’ (Richard Tarnas, 1991, p303) As a result of these developments some scientists and philosophers have claimed that the only statements which can be considered meaningful are scientific statements (that is, those that can be supported by evidence from our senses). Therefore all religious and metaphysical statements or questions such as ‘I believe in God’, ‘Does life have a purpose?’ ‘Is there life after death’? are meaningless. This has given rise to the popular view that scientific language is the only acceptable way to talk about the world. This view is well illustrated in the following quotations: ‘Whatever knowledge is attainable, must be attained by scientific means: and what science cannot discover, mankind cannot know.’ (Bertrand Russell) ‘Truth means scientific truth.’ (Richard Dawkins) Other methods used by science Far from there being one scientific method it might well be that scientists make progress in their field in a variety of ways, some of which involves testing and experiments, others which do not. For example, scientists rely on intuition, hunches, inspirational guesses and leaps in the dark. One of the greatest discoveries in Physics this last century – the General Theory of Relativity – was made by a young scientist called Albert Einstein imagining what it would be like to travel on the end of a moon beam! Scientists also rely on teamwork and, occasionally, on accident such as in the ‘discovery’ of penicillin by Fleming. In the twentieth century the philosopher Karl Popper set out an alternative way of thinking about science. The fact that many scientific developments and discoveries had been arrived at by different means interested Popper. He tried to set out what he regarded as the means by which science actually progresses. He said that scientists begin with a theory, well informed guesses that required to be experimentally tested. However, according to Popper, their theories are tested not to prove them right but to prove them false. When all the scientist’s theories have been shown to be false except one, then he or she can conclude, at least for the time being, that the remaining theory is the correct one. But no theory is safe for all time. Every theory is ultimately only a hypothesis and therefore it is always possible to prove them wrong. His account of scientific method is sometimes known as the ‘falsification theory’. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 11 Science is not enough The scientific method was devised as a more effective way of acquiring knowledge about the world. It was believed that the information that resulted from such a method would be much more reliable than the knowledge acquired by religion. Even the method advocated by Bacon, however, can never establish absolute certainty. No matter how often you throw the switch and the light comes on, you cannot be absolutely certain the same thing will happen the next time you do it. The fact that, as far as we know, every human being that has ever lived has eventually died, makes it pretty certain that we will die too. But maybe we are wrong, one of us may be an exception. These points highlight the limitations of this scientific method and has been illustrated in a comical fashion by the philosopher Bertrand Russell. He suggested that a chicken that awoke to be fed as it had every other day would eventually awake to have its neck wrung! The chicken, on the basis of its everyday experience, assumed that the future would always resemble the past! The idea that the knowledge acquired through scientific methods is the only kind of knowledge worth having has been increasingly criticised in recent years. It is said that it represents a very narrow and blinkered approach to life. Such a view is often blamed for the materialist nature of society which many claim has ignored the spiritual and emotional aspects of life. The trouble with relying totally on science for knowledge and truth is that science seems to leave many questions unanswered as we can see for example in the following quotations from a philosopher and a modern scientist: ‘Why is there something rather than nothing?’ (Leibniz) ‘Why does the universe bother to exist? I don’t know the answer to this.’ (Stephen Hawking) Some people argue that questions like these cannot be answered and therefore it is not even worthwhile talking about them. What we should do is just ignore them and get on with our lives. Others, including some scientists and philosophers, believe that such questions show that important and valuable though science is, it cannot tell us everything about the world. The biologist Steven Rose, for example, believes that science has given us a better understanding of the world than we had, say, a hundred years ago. However, this understanding will never be the whole truth about the world. Being an atheist himself, he nevertheless believes that there are other ways of viewing the world and other ways of understanding it. They come by investigating the world through art, poetry, novels and also people’s own experience. Nor, he says, should we ignore people’s interest in and concern with religion. The twentieth century philosopher, Ludwig Wittgenstein, said that, as far as he was concerned, the things that were really important in life couldn’t be supported by scientific type evidence. In fact, they couldn’t even be stated very clearly! They could only be suggested and pointed to. As a result, Wittgenstein did not have a very high opinion of science. Scientific language and methods were only useful for finding out about and describing matters of fact and logic. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 12 ‘The facts of the world’, he wrote, ‘are not the end of the matter.’ (quoted in Clack & Clack, 1998, p.110) All the issues that matter most to us and have the greatest significance for us lie outside the scope of science. He said that even when all possible scientific questions have been answered, the problems of life will still remain completely untouched. Religious belief Although religious beliefs are passed down from generation to generation, within particular religious communities religions hold that their beliefs are also and more importantly the result of revelation. For Christians the Bible is the central revelation of God to human beings. The Bible is seen as a source of truth about God, revealing that he exists, what he is like, and what he has done in relation to human beings. Christianity claims that God sometimes reveals himself to particular men and women. In the Old Testament God revealed himself to Moses on Mount Sinai giving him the Ten Commandments. In the New Testament they believe that God revealed a new law for humankind through Jesus Christ. Examples of revelation from the Bible are the following: ‘In the beginning God created the heaven and the earth. And the earth was without form and void; and darkness was upon the face of the deep; and the spirit of God moved on the face of the waters. And God said, Let there be light...’ (Genesis 1) ‘And when Jesus was baptised, he went up immediately from the water, and behold, the heavens were opened and he saw the spirit of God descending like a dove, and alighting on him; and lo, a voice from heaven saying, ‘This is my beloved Son, with whom I am well pleased.’ (Matthew 3) Christians regard the Bible as the final authority in matters of faith and practice. Some understand this to mean that the Scriptures provide us with the truth in all matters including History and Science. Others believe that the authority of Scriptures does not extend this far but can be trusted to give the truth about the meaning of life and about God. Religious experience Research shows that many people still have religious experiences. Sir Alistair Hardy and several of his colleagues collected and analysed over three thousand cases of reported religious experiences. He concluded that a large number of people have a deep awareness of some spiritual reality beyond themselves. Those people who have had such a specific, deeply held experience of a spiritual power do not necessarily refer to it as a religious experience, nor do they necessarily belong to an institutional religion. He discovered it often happens to children and to atheists and agnostics and it usually induces in the person concerned a conviction that the everyday world is not the whole of reality, that there is another dimension to life. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 13 More recently, similar work has been carried out by David Hay at the Oxford Centre for Religious Experience. He conducted many interviews throughout the country and found that a high proportion of people claim to have had experiences of a power or presence beyond themselves. Within Christianity ordinary believers often claim to have experienced God, sometimes in the form of dreams, visions or inner voices, or sometimes in the form of extraordinary and miraculous experiences. Among the more famous examples are Lourdes and the Toronto blessing. In his classic study of religious experience, Rudolf Otto coined the phrase ‘numinous’ to describe the sense of mystery which people come to feel in certain circumstances. 1. For example, people are frequently struck with a sense of awe as they gaze at the stars and contemplate the vastness of the universe. 2. They may be overcome with a sense of the beauty and wonder of nature. 3. On the other hand, they can experience a feeling of helplessness as they struggle to deal with some event which changes or devastates their lives. 4. They may have a feeling of being in the presence of something eerie or uncanny which is powerful and awe-inspiring. Otto regarded the disposition to have such feelings as the basis of religion and religious experience. It was, he says: ‘the feeling of ‘something uncanny’, ‘eerie’, or ‘weird’. It is this feeling which,……forms the starting point for the entire religious development in history.’ (Rudolph Otto, 1926, p6) The spiritual dimension It is a popular view that over the last two hundred years science has become the dominant influence on how people in the West see the world and their place in it. Science is often seen as being on the way to explaining everything, to solving all the world’s problems and to making the world a better place and our own lives happier and more fulfilled. It is now clear that far from making the world a better place, science has contributed to some of the worst aspects of modern life. It produced the atomic bomb and is responsible for the pollution of the natural environment by toxic chemicals. Increasingly therefore, western societies are looking to the values of nonwestern societies who have tended to adopt a more spiritual approach to life and relied less on scientific remedies and inventions. There is today, for example, a growing emphasis on alternative medicines as opposed to scientifically produced drug based therapies. Universities are introducing degree courses in areas such as aromatherapy, reflexology and kinesiology. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 14 One of the most important influences in scientific thinking in the twentieth century has come from discoveries in the field of Quantum Physics which studies the behaviour of sub-atomic particles. For example, atoms had always been thought of as solid, the building blocks for everything we see around us. They have now been discovered to be largely empty. As a result the basic material of nature, the atom, can no longer be described simply as hard matter. The world itself is not just a physical object but also includes a non-physical or spiritual dimension. Christians would argue that if the world has a spiritual dimension this is evidence for the existence of God. Another point which many people believe reflects a spiritual dimension in the world is the experience of human life itself. Our own human personality possesses a quality that has to do with what we might call incompleteness. If it is true, as some would argue, that we are all looking for something, it is also true that we never seem to find it. In surveys when people are asked what it is they most want out of life, a common response is that they just want to be happy or to be fulfilled. We always seem to be on the way to being something. As some philosophers and psychologists prefer to put it, we are in a process of becoming. By this they mean that human beings are always on the move, going forward, starting something new, achieving new goals. For this reason human beings have not yet reached the finishing post and face a future in which they still have to shape themselves. We are capable of becoming whatever we want to become and achieving whatever we want to achieve. People who take this view argue that science will never understand everything about human beings, and how and why they behave the way they do. Human beings are not just another problem which science will eventually solve. Scientific theories may give us valuable insights into ourselves from time to time but they will never provide us with a complete understanding because personality is a mystery. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 15 THINGS TO DISCUSS AND WRITE ABOUT Why do you think many people believe that the knowledge coming from science is more reliable than that which comes from religion? What do you think? Using examples, explain what effects new scientific knowledge has had on religious belief. Explain what is meant by the ‘scientific’ method? Why do you think the scientific method has proved such an effective challenge to religious belief? Can all aspects of human life be investigated using the scientific method? Are there any aspects, in your view, which are not open to this method? Why or why not? ‘What science cannot discover, mankind cannot know.’ How far do you agree with this? ‘The facts of the world are not the end of the matter.’ What do you think Ludwig Wittgenstein meant by this? Do you agree with him? Give reasons for your answer. What do religious believers mean by ‘revelation’? Describe an example of a religious experience. What evidence is there that religious experience is widespread? What did Rudolph Otto mean by religious experience? What objections might some people make to the claim that religious experience is proof of God’s existence? What do you understand by ‘the spiritual dimension of life’? Can the tensions and misunderstandings between science and religion ever be resolved? RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 16 4. HOW DID THE UNIVERSE BEGIN? The size of the universe According to astronomers our star, the sun, is one of about 100,000 million stars in our galaxy, which is called the Milky Way. And there are reckoned to be 100,000 galaxies in the universe. The sun is about 100 million miles away from us and the next nearest star is about two million million miles away from us. Our galaxy is about 50,000 million million miles across. Some of the most distant things that can be seen are thousands of millions of millions of millions of miles away. It’s so big you just can’t imagine it! We can’t be sure that there are other planets just like our own which can support life. However there are so many stars like our sun that, even if only one in a hundred has planets, it means there are a great number of planets. And even if only one in a hundred of those planets is at a suitable distance from its star to support life, that’s still a lot of stars with planets able to support life. Also, for about fifteen billion years the universe existed, so far as we know, without any human beings to observe it. And human life will probably come to an end at some point as the earth and similar planets become uninhabitable through cold or heat. The Big Bang theory The universe then is very large but was it always like that? What do we know about the origin of the universe and how it developed? Although, of course, no one was there to see it, what scientists think happened was that there was an enormous Big Bang. At the beginning everything was concentrated into a very, very dense spot (for want of a better word) and this exploded. Out of that explosion came everything: all space, all time, all matter, all energy. And since then it has been gradually expanding and cooling. At first it was a great ball of energy, but with time it has turned into matter. It all came from the Big Bang about 15-20 thousand million years ago. There are essentially three pieces of evidence for the Big Bang. The first is that the galaxies are still moving apart as a result of that great explosion. We can tell this because the light we get from them is redder than you would otherwise expect. This is what you get if a source of light is moving away from you at speed (something like the noise of a police car’s siren which is lower the faster it moves away from you). This points to them all having been in one place at one time. Second, as with any big explosion, the Big Bang was accompanied by a blinding flash of light. The cooled down remains of that flash are still about in the universe and have been detected and measured by scientists. Third, scientists have been able to measure the proportion of different kinds of atoms in the universe and these proportions are exactly what you would expect to come out of the conditions which existed at the time of the Big Bang. In the light of this evidence there is almost universal agreement now among scientists that the universe began with a Big Bang. There are those, however, including some scientists, who do not accept this conclusion. These include members of the Creation Science Movement a UK organisation devoted to upholding the literal interpretation of Genesis, with its account of the creation of the world in six days. They say that the evidence is not so conclusive as is generally thought. They also argue that the Big Bang theory has to assume that at one time there was nothing and that nothing eventually exploded into everything. They say you can’t get something from nothing. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 17 Also the idea that the orderliness of the universe and our solar system arose out of an explosion is surprising. We tend to expect explosions to give rise to chaos rather than order. Genesis For other Christians this approach appears to fly in the face of the scientific evidence bringing religion into headlong collision with scientific judgement. Moreover, say these Christians, there is not one creation story but two. The second story in fact contradicts the first in several important respects. Nor is there is any attempt by later editors to smooth out the contradictions. For example, the first creation story begins: ‘In the beginning God created the heavens and the earth; the earth was a formless void and darkness covered the face of the deep, while a wind from God swept over the face of the waters. The God said, ‘Let there be light; and there was light.’ The story goes on to describe how God created the world over six days and ends with God blessing the seventh day and setting it apart as a special day because by that day he had completed his creation and stopped working. The second story, written perhaps 400 years earlier, begins at chapter 2, verse 4: ‘When the Lord God made the universe, there were no plants on the earth and no seeds had sprouted, because he had not sent any rain, and there was no one to cultivate the land.’ The second story goes on to describe humankind’s first home in the Garden of Eden, which the first story did not mention. In the first story male and female human beings were created together; both formed part of ‘adam’, that is, ‘humanity’. In the second story, however, Eve was created after Adam. Whereas the first story presents the world as a very ordered and well regulated place, the second story describes the world as much more complex and mysterious. In particular, there were two magical trees in the garden, the ‘tree of life’ and the ‘tree of the knowledge of good and evil’. God forbade Adam to eat from the tree of knowledge but gave no reason. Finally, in the first story God says that the whole of creation is good, but in the second story a talking serpent is introduced into the Garden which persuades Adam and Eve to eat from the forbidden tree and rebel against their creator. In a recent book, Karen Armstrong maintains that since the stories appear to present us with different versions of the creation it is likely that neither is intended to be historically accurate. Also by presenting two obviously conflicting creation stories, the Bible editors were making an important religious point namely, that no one human account can ever contain the whole truth about human life. The authors could see, for example, that there was order in the universe, but they were also aware that the world was a mysterious and dangerous place. They lived in a society where women were the social inferiors of men, but in portraying the simultaneous creation of men and women in the first creation story, they also sensed that there was more to be said: ‘By allowing these contrasting views of creation to coexist side by side, the Bible makes it clear from the very beginning that it will not give neat, tidy answers to questions that simply do not admit of a simple solution.’ (Karen Armstrong, 1996, p19) RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 18 These Christians give a number of reasons why the Big Bang theory is compatible with the Genesis story of creation: The stories are written by people of faith for people of faith. There is no attempt to reason things out, to prove anything or to present any evidence. The stories are more concerned to place before us what they believe to be ultimate explanations relating to God, ourselves and the world in which we live. The creation stories are using the language and imagery of poetry rather than the language of the scientific laboratory or of any scientific theory. They are not concerned with geology, physics or astronomy. To try to read the first story as if it were a scientific account of the origin of the world can only lead to endless confusion and useless debate. What scientists are telling us is how they think the universe as we know it came about. The emphasis is on the ‘how’, what the stages were in the development from the Big Bang to the present day. What the writer of Genesis is grappling with is much more questions of ‘why’. Why is there a universe and what sort of universe is it? Why are we here?, Why do we suffer?, Why do we die? The First Cause For many Christians and scientists the question of whether something can come out of nothing lies beyond the remit of science. It is something, they say, science cannot answer because science is based on observation and ‘nothing’ cannot be observed. But is it possible to offer some kind of explanation? Does it make sense to ask, ‘What caused the Big Bang? Some scientists believe that an explanation of sorts is possible by considering that branch of science called Quantum Physics, which deals with and molecules, atoms and sub-atomic particles. Quantum Physics says that unpredictability and uncertainty affect everything that can be observed or measured. This means, that in the laboratory events can occur for no apparent reason. A radioactive atom, for example, might decay just like that, for no reason. So could the universe have occurred in the same way, spontaneously? The physicist and popular science writer, Paul Davies, argues that we have two choices when it comes to the origin of the universe. One is to say that it was a supernatural event, and as a result we can’t really enquire any further. The other is to find some way of treating the whole thing as a natural event. But if a natural event can occur once, it can occur many times. Consequently, he argues, if we are going to use Quantum Physics or any other kind of science for that matter, to explain the origin of the universe as a natural event, we have to be prepared to admit that there could be many other universes that can originate in the same way. It is this idea that has given rise to the theory of parallel universes, the view that all possible alternative universes are equally real and exist in parallel with one another. These parallel universes are physically separate from each other. We cannot reach them no matter how far we travel through our own space and time. Some scientists believe that science will eventually be able to offer an explanation as to how the universe might have come into existence without any intervention – without anyone doing anything to make it come into being. We would then be able to see how it came from absolutely nothing. And if we can do that, they argue, it would be a pretty strong argument for saying that you don’t need a creator to do it. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 19 So where might God fit into all this? Could the origin of the world have a supernatural explanation? Certainly, arguments about whether the universe had a first cause have a long history. The First Cause argument is sometimes called the Cosmological argument because it is an attempt to prove the existence of God by reasoning back from the existence of the cosmos or universe. The ‘First Cause’ argument was put forward most famously by Thomas Aquinas in the thirteenth century. He argued that it is possible to ask a question about the cause of any particular thing that happens to exist. For example, we might ask what caused our own existence and answer the question by referring to our parents, when they met, when they got married and when we were eventually born. But that could never really be a complete explanation because we have not yet explained how our parents came to exist. Any explanation of our own existence has to include an explanation of how our parents came to exist, and their parents, and so on back through the generations. The explanation for our existence therefore involves a long chain of explanations stretching back to the beginning of time, and this applies to everything. According to Aquinas the chain of explanations or causes can’t go on for ever; so there must be a ‘First Cause’, whose existence doesn’t require a cause outside itself, to bring the chain to an end. The only being that could possibly be a First Cause in this sense is God. So God must exist. The famous Humanist and philosopher, Bertrand Russell, describes how, as a young man, he claimed to see the fallacy in the argument of the First Cause. While reading an autobiography, he was struck by the realisation that if he and everything else had been made by God, who had made God? He wrote: ‘If everything must have a cause, then God must have a cause. If there can be anything without a cause, it might just as well be the world as God, so that there cannot be any validity in that argument.’ (Bertrand Russell, 1979, p15) What Christians believe about origins It wasn’t just the Israelites who wrote creation stories. There are creation stories from Babylon and from Egypt and indeed from all over the world. They were common amongst ancient civilisations. There are many stories about how the world began out of a struggle between the gods and goddesses. Many of these are identified with what we see around us, the sun, moon and the various planets, the rain and drought and war. In the Genesis story, however, there is only one God. God is not identified with anything in nature. He is different from the world and stands beyond it – he is transcendent. There is no sign of a struggle to create the universe. The universe is an orderly place, a place in which human beings can ultimately put their trust. There is no battle with chaos as in the Babylonian creation story which starts with waters of chaos and monsters of chaos. In that story the creator god, Marduk, has first to subdue the chaos. In the Genesis story the universe comes about simply because ‘God said……and so it was.’ RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 20 According to the story human beings are made in the image of God: ‘In the image of God he created them; male and female he created them.’ This is partly explained by the words which follow in the story. Christians believe that we have been given authority over the rest of creation and are called to share something of the leadership which God exercises. This seems to mean we have been placed in a position of responsibility towards the rest of creation and have to look after other species and the environment. We have already seen that some Christians do not accept the Big Bang theory and maintain that the universe was created in six days, as described in Genesis 1. Clearly there were no eyewitnesses who could have seen what God did as He created the world. Nobody could have known what he thought and said. Some Jews and Christians, in an attempt to explain how the biblical authors came by this information, have claimed that God himself must have dictated the text to Moses. They agree that there is a great deal of poetry in the Bible, in the Book of Psalms for example. But the early chapters of Genesis, they argue, including the creation stories, were always regarded as history by the early Church. Other Christians say that the Big Bang theory and indeed any scientific description of the origin of the universe is compatible with an understanding of God as creator. When Christians talk about God as creator they are saying that in the end, the existence of the universe depends upon God. The universe is not self-sufficient. Its existence can’t be explained without bringing in God. But precisely how or when the universe came about is a matter for scientists to work out.

HOW DID LIFE COME ABOUT? The theory of evolution Charles Darwin’s best known work on evolution, The Origin of Species, was published in 1859, twenty years after his return from his famous voyage on HMS Beagle. Darwin was not the first person to think about evolution, the idea that living things evolved from each other and were not simply created in the form in which we now see them. From as early as the fifth century BC there were people who tried to describe the origins of life in evolutionary terms. Darwin was the first to present a coherent theory which has stood the test of time. His theory of evolution by natural selection has two main elements, competition and variation: Darwin said that all living things were bound to produce more offspring than their environment could support. So, inevitably, all creatures were bound to be thrown into competition with their fellows. Individuals of the same species vary. One antelope is very much like another but they are not identical; some run faster than others for example. As a result the ones that are best adapted to their circumstances, for example, most successful in escaping from predators such as cheetahs, are the ones that survive and produce offspring. And this argument holds for all living creatures - explaining why they have good eyesight, or why they have hands that can grasp in the case of monkeys. In other words, some hereditary characteristics are good for survival and reproduction and some are not. All this goes back 3000 million years although for the first 2000 million it would have been mostly bacterial life. Then about 1000 million years ago life appeared which was built up of many cells capable of being seen by human beings. After that animals and plants appeared which had a shape and form and could have been seen without a microscope. Later there were bigger and more complex creatures like we have today. So what causes the variations in the first place? According to biologists it is mistakes, random mistakes in the molecules we call genes leading to the development of new individuals. Organisms which are well suited to their environmental surroundings will do well, and will pass on copies of their successful genes to their descendants. Organisms that are less well adapted will have fewer offspring, and over the generations the better-fitted genes will dominate. If it is the most successful genes that are passed on there must be some variety from which to select. This variety arises from the mistakes or imperfections that take place during the copying process. In this way evolution moved from the very early beginnings of life through to human life itself. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 23 Creation The controversy surrounding the publication of Darwin’s books on the theory of evolution by natural selection (in 1859 and again in 1871) resulted in a media circus regarding every supposed clash between scientists and theologians. Typical headlines were: ‘Darwin makes a monkey out of man.’ and ‘ Man is but a worm.’ There was no clear cut division between scientists and theologians. Many scientists rejected evolution, while many theologians had much sympathy with Darwin’s theory and, simply regarded evolution as God’s mechanism for creation. But for others it was a challenge to all that was sacred. A very gradual process of evolution, in the view of many, was not compatible with the six days of creation and the fixity of species implied in Genesis 1, or indeed with Eve being created from Adam’s rib in Genesis 2. All of this had been considered the literal truth revealed by God and therefore could not be mistaken. It was on the basis of the stories contained in Genesis that many Christians, both scientists and non-scientists, objected to the ideas of Charles Darwin. It was not so much the general idea of evolution which they objected to. After all it was possible to suppose that, in the beginning, each type or species had been created separately by God and then was gradually changed by evolution. What really offended them was Darwin’s view that one species could change into another, and that present-day living things may all have evolved from just one first ancestor. This appeared to contradict the Genesis story in the Bible quite directly and to disprove its description of how life came about. Many Christians today, however, take the view that the scientific theory of evolution by natural selection does not conflict with their religious beliefs. In particular, they argue that those who rejected Darwin’s theory because they thought it conflicted with the account of creation in the Bible have been proved wrong. Augustine, who lived in the second half of the fourth century, was one of the first to realise that the creation stories were not to be taken as literal descriptions of physical facts. Today, many Christians point out that in the biblical stories of creation, the language and imagery belongs much more to the world of story and imagination than to the world of the laboratory and scientific research. Also they believe that there are two creation stories in Genesis, neither of which can be regarded as historical. (see section on ‘How did the universe begin’ for more information on the creation stories) Creationism Today many Christians are still unwilling to compromise in any way. They still hold to the idea that the Scriptures cannot be mistaken, even in areas of science. This view has given rise to ‘creationism’ which completely rejects the theory of evolution and holds that all species have been directly created by God in the way described in the opening chapters of Genesis. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 24 Creationism is particularly strong in the United States where polls suggest that a significant proportion of the adult population reject evolution on religious grounds and where many schools present the Genesis story as an accurate scientific account. Last year the American states of Kansas and Kentucky agreed to omit the teaching of the theory of evolution from its school curriculum and to exclude any reference to Charles Darwin. Creationists believe that there is no strong evidence to support the theory of evolution, particularly the scientific position that new species can develop from existing species. They refuse to accept the belief that life on earth began almost 3000 million years ago because they believe the book of Genesis is telling a completely different story. The story of creation in Genesis is regarded as historical and describes the creation of the world in six days. Nor do they accept the fossil evidence, saying that it is impossible to be entirely sure how old the world is. They also believe that the theory of evolution is turning people away from God and weakening the emotional and moral well-being of society. (Independent on Sunday, 26 March 2000) Design argument Until the publication of Darwin’s work, Christians had relied on the so-called ‘design’ argument to support their belief in the existence of God. The design argument looked to the variety, order and beauty of the natural world. When we look around the world we find so much that is beautiful and ordered that we feel bound to say that it must have been created or designed. In nature the various parts of the body of humans and other living creatures are so well suited to fulfil their respective functions, it seems only logical to conclude that ‘Someone’ must have designed them for those purposes. The argument from design takes the order and apparent purpose in the world, and moves from that order and purpose to suggest a designer, God, who must have been responsible for it. The most famous version of the design argument was set out by William Paley in the eighteenth century. Suppose you are walking across a heath, says Paley, and you knock your foot against a stone. You might think, if you were to think about it at all, that the stone had always been there. This would, in the circumstances, be a very logical answer. But if you were to come across a watch, then you would naturally ask where the watch had come from; you would not in this case naturally conclude that it had always been there. You would wonder who had made the watch and for what purpose. Paley uses this story as an analogy for the universe. Like the watch, the universe requires a creator or designer to explain its existence, because it is just as complex a mechanism, perhaps even more so. For Paley then, the universe resembles a watch in its organisation and complexity, although on a much greater scale. Its existence can only be explained by reference to some external intelligence. Surely, therefore, there must be a cosmic designer who has made and arranged the world in the way it is for a purpose? RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 25 Darwin’s theory of evolution by natural selection was a major challenge to the argument from design. It presented an alternative explanation of how life on earth came about. It also suggested that the variety, order and beauty of the world was not the result of a Creator God but the result of a purely natural process. In the theory of natural selection, accidental chance mutations rather than the purposeful work of an intelligent being lay behind the existence of the world. Critics of the design argument have first of all questioned the validity of the analogy between a watch and the universe. Is it an appropriate analogy? In some ways the universe is better described as a living organism with all living things depending for their survival on each other. If the world is like a machine then the claim that there is a designer would make some sense. But if the universe is more like a vegetable, as the Scottish philosopher David Hume suggested in the eighteenth century, then the idea of a designer seems inappropriate. In any case, aren’t there just as many examples of ugliness as beauty within Nature and as many examples of disorder as order? And even where there is a kind of order, as in the way plants and animals adapt to their environment, isn’t that explained by Darwin’s theory of natural selection? For many people, the essential feature of Darwinian evolution is its accidental nature. Variations occur by blind chance. As a result of these purely random changes in the characteristics of creatures, Nature is provided with a wide range of options to select from on the basis of what is more suitable or advantageous. On this basis, they argue, the theory of evolution by natural selection is on its own sufficient to explain how life came about. The element of chance even operates outwith natural selection. For example, most biologists agree that dinosaurs did not become extinct because of the development of mammals. It was much more to do with chance in the form of a dramatic change in climate. The dinosaurs could be with us still and might have dominated the earth until the earth itself died out. In short we are lucky to be here! There would appear to be little room in all this for any kind of guiding hand to be involved. If human beings evolved by chance, they can’t have been created by God. Since Darwin many scientists have continued to see Christianity as incompatible with evolution. A leading proponent of this position today is the Oxford zoologist, Richard Dawkins. His book, ‘The Blind Watchmaker’, has the subtitle ‘why the existence of evolution reveals a universe without design’. Dawkins sees no need at all to bring in the idea of a creator God. The theory of evolution is on its own sufficient to explain life. He argues that if there was a God, he would never have created the universe by evolution. He would have surely done it directly over a much shorter period. By choosing evolution as his method of creation he has completely covered his tracks and made it impossible for human beings to appreciate him. On the other hand, if he did create the universe this way, it makes him out to be totally indifferent to human suffering because the consequence of natural selection is suffering on an enormous scale all over the world. It’s not that nature is cruel, it’s just that it is totally indifferent and is only concerned to maximise the survival of the genes. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 26 The Anthropic Principle More recently, in his book The Existence of God, Richard Swinburne presents a slightly different version of the design argument. He believes that the order we see around us is a remarkable fact and points to the fact that the world runs according to regular laws. Swinburne argues that some explanation is required for the striking orderliness of the universe. It is not enough to say that this is because of the existence of scientific laws. After all, it is these very scientific laws that we should be trying to explain. He contends that God is the only explanation for the existence of scientific laws and the orderliness of the universe. Others have gone further and pointed out that even the slightest changes to these laws would have made the evolution of life impossible. In other words the existence of life seems to be dependent on a very fortunate combination of underlying laws and conditions. Scientists studying evolution have been struck by how easily it could have developed in a multitude of different ways that would have prevented life from actually emerging. For example, had the universe exploded with somewhat greater energy, it would have thinned out too fast for the formation of galaxies and stars. If the energy had been a little less, gravity would have quickly got the upper hand and would have pulled the universe back together again. If there had not been a dramatic change in the climate 65 million years ago dinosaurs might have continued to dominate the earth. In some ways the Anthropic Principle can be seen as supporting the design argument for the existence of God, or at least for some creative purpose behind the universe. Everything seems to be very carefully and precisely arranged for the eventual emergence of life and human life in particular. This extraordinary set of circumstances, making for the development of life against seemingly impossible odds, has been called the Anthropic Principle. (Russell Stannard, 1996, p27-29) Some people counter the Anthropic Principle by arguing that there are in fact many worlds that could possibly evolve with slightly different conditions. Ours just happens to be the one where the conditions produced life. It’s pure chance, just an extraordinary set of coincidences. The Anthropic Principle can also be seen as simply saying that the universe must be the way it is because we are here, it doesn’t point to a designer God at all. If the universe had turned out differently we would not be here to think about it and observe it – and that’s all there is to it! Meaning and purpose For Christians, meaning and value in life is related to the existence of a God who created the universe and made human life possible. Darwin’s theory of natural selection presents a serious challenge to the Christian view that life has meaning and purpose. The theory of natural selection appears to replace God’s creative activity with a wholly impersonal and natural process. As a result it becomes difficult to argue that human beings have a special place in the scheme of things, that they are part of an overall divine plan which gives meaning and purpose to life and the universe. It is often this issue about the meaning of life that creationists are concerned about when they object to the whole idea of evolution. They feel that to accept evolution as the method by which life came about means to remove God and therefore to remove all meaning from life. If there is no God then life and the universe can have no meaning. RMPS Support Materials: Nature of Belief: Science and Belief (Int 1/Int 2) 27 Many Christians are quite happy, however, to accept that God brought living things into being through a gradual process of evolution. There is no more difficulty in thinking this, they argue, than in thinking that creation happened all at once. Indeed the evolutionary account of how life came about is even more impressive. In other words they see the idea of that life came about through a gradual process as even more evidence of God’s creative activity. Evolution, they argue, had an in-built capacity for moving from simple forms of life with little or no consciousness to more complex forms with a high level of consciousness, that is human beings. In other words the fact that complex beings who possess consciousness and hold values have developed out of simple atomic particles, strongly suggests that there is a purposeful Hand underlying the whole process. Some Christians also take the view that the ‘randomness’ and ‘chance’ element in the evolution of the universe is in fact an essential feature of God’s creative purpose. It lets in some freedom, some openness, some creativity. It means that everything is not preordained from the beginning. The new and the unexpected can occur. However, this element of chance is not so large that it cancels out God’s ability to control where the universe is going in a general way. In this way many Christians have been able to adopt a faith which is more rational and compatible with scientific theories of how life came about.
