Professor Tom McLeish – Towards a theology of science

Here is a reblog from my recent visit to the University of Queensland Emmanuel College Centre for the Study of Science, Religion and Society. There’s also a rather sharp set of questions over 20 minutes at ABC Radio embedded!

Emmanuel Centre for the Study of Science, Religion & Society

On 15 September Tom McLeish, Professor of Physics at Durham University, gave incredible insights into the breadth of his research in two presentations at the CSSRS.

Tom McLeish seminar

McLeish spoke at a lunchtime seminar about his recent OUP publication Faith and Wisdom in Science in which he argues that the problem with the contested “science and religion” relationship lies in the conjunction. Neither science nor religion, he contends, does “and”. Instead, McLeish posits a case for the importance of a “theology of science”. In a fresh reading of the book of Job, McLeish argued that science — as the attempt to understand the natural world — is a deeply human and deeply religious activity. Focusing particularly on the passages that detail God’s response to Job in chapter 38, McLeish argued that questions like “canst thou bind the sweet influence of Pleiades, or loose the bands of Orion?” are not only musings…

A Tour of Creation in the company of Job – towards a Theology of Science

Last Sunday I experienced the great honour of being invited to give the first of a whole term of Sunday Evensong sermons at St. John’s College Cambridge, all on the subject of Science and Religion.  The very interesting remainder of the programme can be found here (where you can also hear audio recordings of the sermons after they are given).  This is what I said, in an attempt to build a Biblical Wisdom foundation for the rest of the series.

Interior of St. John’s College Chapel, Cambridge

I am doubly grateful for the invitation here tonight – the first reason is rather personal actually and until now has been a secret: during my own Cambridge days I was a member of a very much lesser College Chapel Choir, and every so often I loved to sneak away and come to this place for Evensong – to hear, as it were, how it’s done properly, as well as to be mesmerised by George Guest’s conducting and wonder what magic made it work. I have been reminded of the reason I did that this evening in the most beautiful possible way: Choir, Director of Music – thank you. The second reason I’m so delighted is your imaginative decision to use this term’s Sunday sermons to explore the relationship of science and faith. You have invited some real experts later in the term, and it’s an immense privilege to introduce the series. Getting thinking on this right, you see, – and believe me most public chatter on the topic is nowhere close to doing that – is not just an academic sideshow, but about understanding how to live as humans in a natural world with which we have an increasingly delicate and threatened relationship.

But where should we start? If this were a lecture room I might be tempted to a survey of the torrid landscape signposted ‘The Science and Religion Conflict’. But this is Evensong – the most Biblically-soaked liturgy of the prayer-book. So why not instead begin with the greatest example of ancient writing about the human intellectual engagement with nature? The Book of Job has puzzled, troubled, exasperated and inspired writers and thinkers of many faiths and none for millennia, from Basil the Great to Emmanuel Levinas. I will never forget my own first reading. I like to shock my scientist colleagues by suggesting that the greatest science poem ever written is buried in the heart of the Old Testament Wisdom literature – the ‘Lord’s Answer’ to Job from which we heard an excerpt earlier. And when they read it they almost always return with surprise and delight. For here in beautiful, searching, poetic language are the core-questions of what have now become the fields of astronomy, meteorology, geography, zoology, to paraphrase…

… do you know what binds the Pleiades star cluster?

Faith and Wisdom in Science (OUP 2014)

can you trace the path of the lightening?

do you know how the eagle navigates her way to the south?

No of course you can’t find the word ‘science’ in a Bible concordance, but if we think for a moment about what science is, what it does for the human condition of initial ignorance and fear in the face of a wild, puzzling and threatening world, and if we think about science as the human activity that meets the need to mend that ragged relationship with nature, we find a key that unlocks creation-writing like this all through the Bible. We also see that, although science in its current form is recent, it is, if you like, the name of the current chapter in a book that humanity has been writing for as long as songs have been sung or prayers prayed, or stories told.

The other reason that scientists respond so radically to the Lord’s Answer to Job, is that we know that the central imaginative move in science is not to find the right answer – but as Werner Heisenberg once put it – to formulate the creative question. I find myself explaining to every new doctoral student who joins my research group in Durham that all the skilful mastery of answering exam questions well, the very skill that brought them to this place, will be of very little help now. Can they, rather, ask the imaginative, the creative question? Do you know the laws of the heavens – and can you apply them to the earth? Such connected cosmic thinking staggers me now as it does when I first read it – and look where that thought led!

So why has ‘The Lord’s Answer’ received such bad theological and biblical-studies press? The critics are, in the main, unimpressed. ‘What sort of an answer is a hundred questions?’ they complain. And in any case – the monologue doesn’t even address Job’s complaint. For his accusation is that YHWH is treating him unjustly – Job’s is a moral issue. He, the epitome of righteousness, after losing family, wealth and health, is suffering inconsolably (and he is not helped by the moralising efforts of his inept friends and their brittle theologies that only the sinful person gets to suffer, while only the good prosper). All God seems to do, when eventually he arrives on the scene, is to ask a bunch of unanswerable questions about nature: to paraphrase the critique – ‘Hey Job! You don’t know where the snow comes from? You any idea what light is? Well, you don’t know nothin’ then do ya? So shut up’. ‘Not the YHWH of the Pentateuch, but a petulant put-down deity’, wrote one critic.

But I wonder – for if you pick up a Bible later this evening and read through those first 37 chapters of Job’s three cycles of speeches with his friends, you will find that nature-talk is threaded throughout that long and increasingly tense dialogue too. In fact there isn’t a natural object, not a tree, not a rock, not a cloud nor a lightning strike, appearing in the Lord’s Answer that has not already appeared somewhere in those early dialogues. And the reason for that is that Job’s accusation, you see, is a double one. He accuses God of being as out of control of the moral world as he is of the physical universe. Both worlds seem to Job to be in chaotic disarray. From chapter 12 he rails against YHWH for the chaos of flooding

He holds back the waters, there is drought; he lets them loose, they overwhelm the earth.

Or from the discourse in chapter 14 plucks from land-erosion a metaphor for despair:

Yet as a mountain slips away and erodes, and a cliff is dislodged from its place, as water wears away stone and torrents scour the soil from the land – so you destroy man’s hope.

So I wonder again – if Job’s trouble is that the universe is out of control, chaotic, unpredictable, destructive, if he is at the sharp end of the realisation of what George Steiner called ‘the inhuman otherness of matter’ – then is it so very inappropriate that when God meets him, that he should invite Job to stand up alongside his Creator and to contemplate how one makes a world? Not an ordered, crystalline, dead world – but a world full of dynamism, of branching life, energy, and intelligence:

When all the angels sang for joy ... Job Ch. 38

When all the angels sang for joy … Job Ch. 38

Where were you when I laid the earth’s foundation? … Who laid its cornerstone while the morning stars sang together and all the angels shouted for joy?

Job’s questioning ‘tour of creation’ is a way of helping him understand that neat and ordered worlds are all very well, all very well that is if you have a taste for dead worlds. The messiness of a living physical world is not so very far removed from the messiness of a real moral world – but Job, and those who read faithfully the book that bears his name, are invited to engage with the process of understanding, of healing, of making peace with, both of those worlds.

Once you are attuned to the way creation-stories are used in the Bible, and to the short and compressed form in which they usually appear (Genesis is an exception you see), then you will find accounts of the creation of the natural world throughout Old and New Testaments alike. Paul’s epistles are no exception – and in our second passage this evening we heard one, from the letter to the Romans, that surely has its roots in Joban thinking. Here Paul is reaching the climax of his great systematic exposition of the gospel. Like Job he wants to go to the place of reconciliation – the point at the end of chapter 8, often read at funerals, where nothing, not height nor depth, nor anything else in all creation, will be able to separate us from the love of God. But first he has to pass through the messy birth-pangs of a new creation – and here is the vital point for us – it is the relationship of redeemed human beings to the physical creation that conveys hope – listen –

the creation itself will be liberated from its bondage to decay and brought into the freedom of the glory of the children of God.

If the consequence of our own reconciliation with God through the cross and resurrection of Christ is that now we, too, can minister reconciliation to others; or to paraphrase Paul, if Christians are now in the business of healing broken relationships, then one of them must be the humble, but troubled relationship between human beings and the natural created world around us. Like all broken relationships, we mend it by working to replace ignorance with knowledge, fear with wisdom, and mutual harm with mutual flourishing. Set in those terms, that begins to sounds like the basis for theological thinking about what science might be for.

It’s so important to ask the right questions. The wrong questions in science just send us round and round in circles; the right ones on a real journey of discovery. ‘Can you reconcile science and religion?’ is an example of the wrong sort of question, respecting neither science nor religion nor history. ‘What does the gift of science do, and what service might it achieve within the Kingdom of God?’ is surely a much better question. It is certainly one that our nature-soaked scriptures being to ask. And I wish you every delight as you work to answer it over the term ahead, and if you are a scientists, within your own calling.

Faith and Wisdom in Science goes Down Under

I am at present enjoying a warm, stimulating and rich visit to several universities and colleges in Australia and New Zealand at the invitation of ISCAST (Christians in Science and Technology) and the University of Otago.  At each stop there is a chance to discuss the Faith and Wisdom in Science approach to a theology of science, and also present research on biological physics and on the Durham and collaborators project on medieval science, at relevant departments and centres. ISCAST have a page listing all the events in Australia here, so I wont list them again.  But  in Otago I will be talking about Interdisciplinary research as well as a Public lecture on the Faith and Wisdom in Science theme in their Centre for Theology and Public Issues.

KangasI had a remarkable first 3 hours in Australia.  The flight landing at 6am gave me a few hours for a breather with my affable host the ISCAST President Alan Gijsbers.  We took off to the glorious Westerfold Park in greater Melbourne – ‘would you like to go find some kangaroos?’.  And here they are looking alert and somewhat suspicious of my close and stealthy approach (stealthy for a clumsy pom that is) just before they took off.  The mother with pouched joey bounding as ably as the large males in the group earns every admiration.

Then we walked on to a bridge over the river Yarra, within the park.  Conversation continued as we gazed down towards the muddy waters.  Then there was an intriguing and oddly-shaped dark swimming animal right below us on the surface. ‘Oh look Alan – there’s a platypus’ I commented, not expecting much interest.  After all this WAS Australia and we HAD just seen a mob of kangaroos on land, so on water ….  Alan exploded with astonishment.  He has lived Platypushere for a number of years that it would be impolite to specify and this (photographed by him as it dived) was the first ever sighting by him of one in the wild.

Such good fortune has stayed with me so far during the trip in continued sightings of and conversations with rich and rare Australian human wildlife.  The questions and discussions at presentations of the wisdom approach to a Theology of Science have been as insightful as they are stimulating, from the Alan Day Memorial lecture in Melbourne, to a Tabor College Public Lecture in Adelaide, or an Emmanuel College lecture within the Centre for the Study of Science Religion and Society.

The discussion has been deepened by questions that will challenge a lot of further thinking:

  • What does a wisdom theology of science say to inform a responsible policy of forestry management? (think about it – this is a GREAT question to bring the strands together into a practical focus, and posed by Richard Gijsbers, former forester himself).
  • Does the ‘faith and wisdom’ critique of natural theology open up a new way to understand Karl Barth’s approach to the relation between theology and creation?  (I had previously absorbed a rather naïve view that Barth is not strongly relevant to a science faith dialogue, but this was hasty)
  • With Richard Gijsbers in the forest talking environmental theology in situ!

    With Richard Gijsbers in the forest talking environmental theology in situ!

  • Does the relational and invitational interpretation of the Lord’s Answer to Job add any insight to the way it might have been read in Hebrew context?  (Now this is a vital question, but a hard one as we don’t really know what the historical context was, though the exile is a good start…)
  • What is the role and meaning of ‘fear’ in the reconciliatory work between humans and nature?

This and more should keep this channel hot for a while.  And we still have Sydney and all of the New Zealand leg to go. More anon I should think.

What do Creation Stories do in the Bible?

Earthrise captured by the Apollo 8 mission in December 1968.

One of the central themes of Faith and Wisdom in Science is the rich seam of creation-story material in every genre of Biblical literature, yet the strange paradox that, apart from some notable exceptions, this is largely ignored in the mainstream science/religion discussion.  As a further damaging consequence, when that debate ever resumes its close Mercurial orbit around the well-trodden turf of Genesis 1 and 2, interpretation of those texts become distorted without the foundation of creation story material in Psalms, Prophets and supremely the Wisdom books.  Since I claim that all this material is fundamental to answering a theological question about what science is for, as an essential prelude to how we govern and use science in our time, a close study of the whole Biblical picture of our relationship with nature assumes supreme importance in the church today.

A previous post, The 20+ Creation Stories in the Bible, did not much more than list some of the material that needs to be brought together in an healthy Bible-study program on creation.  That post pointed out that Genesis has by no means the monopoly on creation stories.  There are fundamental alternative images and language used in, for example, Proverbs 8 and Job.  Ah! The wonderful Book of Job! I drew attention to the reception of the creation story tradition in the New Testament genres of Gospel and Epistle too.  But there is more, of course, to say here.  We need to think about the role creation-stories play in the Biblical narrative, where they occur, in what moods and what the achieve.

Take Psalm 33. It follows hard on the heels of the penitential Psalm 32 (When I kept silent, my bones wasted away through my groaning all the day long – 32v3).  The last verse of Ps32 and the first of Ps33 have turned this backward looking reflection on transgression and decay into an exhortation to praise, but it remains at this point a command.  There is no source of transformational energy to effect it. The narrative is moving towards the closing verse of Psalm 33: We wait in hope for the Lord; he is our help and our shield.  But in order to reach that closure, the psalmist needs to chose a path that goes by way of a creation story:

By the word of the Lord were the heavens made, their starry host by the breath of his mouth.

He gathers the waters of the sea into jars; he puts the deep into storehouses

its important to note that all the fundamental components of a Biblical creation story are here: the formation of boundaries, the ordering of chaos, the action of Word.  All this is embellished and formalised in the Genesis narratives, but the essentials are bridgeall in these shorter accounts in Song and Wisdom. The point here, however, is that the story of Creation, rather than just standing at the beginning of time as a monument to the first moment, becomes a bridge from despair to hope.  This active transport of the contemplation of the creative act through the process of healing and redemption, the bridging from fall to new creation, is ubiquitous when you have once recognised it.  The delightful, playful Wisdom-generated creation story in Proverbs 8 serves the same purpose.  Like Psalm 33, it answers a ‘call’ (this time not a call to praise but a call to wisdom) but lacking in the source of power to realise it, by unleashing the energies of God’s creation itself to create hope, and a direction towards the enacted Wisdom of the rest of the book of Proverbs.

The great creation story in the Lord’s Answer to Job (Ch 38) BlakeonJob

Where were you when I laid the earth’s foundation? Tell me if you understand.

Who marked off its dimension? Surely you know!

Who stretched a measuring line across it? On what were its footings set,

or who laid its cornerstone while the morning stars sang together and all the angels shouted for joy?

serves the bridging need once more.  It resolves the tangled and angry impasse of the cycles of dialogues between Job and his comforters (who are of course rather accusers), expands the creation motif into a panoramic tour of the entire created order, but eventually takes Job to a place where both his body and his mind can be healed.

The New Testament visits Creation and our painful present relation to it in just the same way.  Romans chapter 8 cannot reach its goal of nothing separating God’s servants from their maker except by way of All Creation groaning until the sons and daughters of God are revealed.

The Johannine ‘signs’ may, at least partially, be understood in this light. After the feeding of the 5000 in John chapter 6, redolent with the symbols of the Exodus, the people want to make Jesus king, but by force. Nature itself illustrates this out-of-joint-ness with a terrifying storm that threatens to overcome the disciples in the Galilean fishing boat.  But, bringing three mighty Biblical strands together in one action: (1) a recollection of the crossing of the Red Sea (Exodus 14); (3) a recreation and re-bounding of water in a new physicality (Psalm 93); (3) a fulfilment of the cosmology of Job (Job 9v8), Jesus walks to them across the waves. And the boat immediately reaches its destination (Jn 6v21).

Our relationship with created nature today features science at its heart.  But the role of this relationship, and its Great Story, has not changed.  Mending our ways with creation is still the bridge between the ignorance, fear and waste of our past, and to a future of knowledge and wisdom.  This is what makes a theology of science to urgent to work through and work out.

The Faith and Wisdom in Science Story in Three Steps

Lincoln CathedralIt’s proving a very interesting summer thanks to two invitations to give lectures

Faith and Wisdom in Science (OUP 2014)

Faith and Wisdom in Science (OUP 2014)

and discussions on the material in Faith and Wisdom in Science over three consecutive sessions, rather than squeezing it all into one evening.  The first, in June, was from the West Yorkshire School of Christian Studies (WYSOCS) to deliver the input for their annual study weekend.  The second is from York Minster, to give their annual series of three summer lectures.  The first happened last month, the York Minster series has one more to go (so you can still come!).

I’ve found the opportunity to let the story of the thinking behind the book ‘breathe’ rather more spaciously very stimulating, and satisfying.  The narrative is less rushed, preparatory material can be enriched, and – best of all – we can devote almost the entire second lecture to a good wallow in the Book of Job and its wonderful nature poems, painful questions and search for Wisdom.

The WYSOCS audio files can be found here, for those with the patience to hear them, and I will be posting the slides on the Minster web site in due course. The three-section structure for FaWiS goes something like this:

  1. A historical summary of relation between science and religion
  2. The search for Wisdom: Creation stories in Psalms and Proverbs, and the Book of Job
  3. Through the New Testament and towards a Theology of Science

The first hour and discussion can set the scene – how did we get into this mess?  We look at Tertullian’s infamous ‘What has Athens got to do with Jerusalem?’ outburst in Against Heretics but in the context of a thinking perfectly able and willing to recruit Stoic logic to his Christian purposes.  Another contrast is the wonderful Gregory of Nyssa whose On the Soul and the Resurrection contains a beautiful forth century therapeutic application of scientific thinking at his sister Macrina’s deathbed.  A little more ‘myth-busting” taking in the scientific advances of the medieval Islamic and Christian worlds, for example, take us to the early modern acceleration of science – and its explicit (Baconian) Christian teleology.  So we find the ‘conflict’ narrative to be a social construction of the 19th and 20th centuries that creates havoc with the social context of science, and in the church.

What we need, then, is a dose of Wisdom – and we turn to the strand of creation stories in the Bible for a taste of writing about human relationship with the nature in the ancient world.  The 20 creation stories in the Bible get a brief overview, as well as bridgetheir purpose.  They are used ubiquitously as bridge texts between present trouble and future hope.  Psalm 33 is a prime example.  We also review them from a structural perspective – their common features of ordering, of setting boundaries between land and sea, heavens and the earth, laying foundations, and finally  the role of Word in the creative act.  The short creation story from Ps33 runs:

6 By the word of the Lord the heavens were made, their starry host by the breath of his mouth. 7 He gathers the waters of the sea into jars; he puts the deep into storehouses. 8 Let all the earth fear the Lord; let all the people of the world revere him. 9 For he spoke, and it came to be; he commanded, and it stood firm.

This takes us into Job, with the structure of circling dialogues, each invoking nature imagery to illustrate Job’s great double accusation – that God is as out of control of the moral law as he is of the natural law.  Injustice flows like the wadis – dry one day and in uncontrolled and destructive spate the next. The Hymn to Wisdom of Job 28 points us towards the wisdom of perceptive searching and seeing into the natural world by weight and measure (this is the Wisdom of God) and towards YHWH’s answer in chapters 38-40.  This is not the ‘petulant put-down’ of some critical readings, but a teacher’s questions of a pupil or debating adversary – and they lead Job into the position of how one creates a world of fruitfulness, life, and humanity, “Were you there when I laid the foundations of the Earth …”.

So by the start of the third session we are building up a picture of a theology of science that is old, deeply embedded into the human, takes a responsible stance as God’s co-workers, is reconciliatory of our relationship with nature.  We are called to replace a relationship characterised by ignorance, fear and harm with one filled out with knowledge, wisdom and mutual flourishing.  That is what God’s gift of science is all about – not a threat to faith, but a gift of talents to exercise it in obedience and humility.  We can spend some time on consequences for public shared science, education, the media, the political debate of science based issues such as climate change, fracking, genetic medicine, that as things are get stuck in immobile oppositional negative narratives of despair.

The longer breath of presentation seems to elicit a deeper vein of question as well.  At WYSOCS I was pressed, for example, on the ‘no prior boundaries’ conclusion – that the Biblical material asks us to take responsibility for what we do and do not do with our knowledge of the world.  So it is not a priori evident that we should not, for example, deliberately manipulate the human genome.  But nor is it obvious that we should just because we can.  In every case we need to take wise, theologically informed, participative, reconciliatory discussion into the public square.  Was there an occasion when there was an experimental piece of research I wanted to do, but which I felt was a theological no-go area?  As a theoretician myself, I am blessed with not finding myself in this position!  However, I am aware of, and was involved in, a discussion with an academic ethical advisor to the Engineering and Physical Sciences Research Council (EPSRC) in the UK about a project aimed at scoping a geo-engineering technology.  It was stopped, and I agreed, because there had been very inadequate public consultation and involvement of the ethical issues, unintended consequences and plan for further public debate, as well as a possible conflict of interest.  It had been framed in an ‘engineers and scientists know best’ narrative.  This is a good example of the application of theological thinking, but in a secular context, to the benefit of our relationship with nature.

More questions and initial directions of answers from WYSOCS and the Minster lectures over the summer!

Laudato Si – Reflections from Faith and Wisdom in Science

rainbowLast week Pope Francis published his widely anticipated encyclical Laudato Si.   It is a considered yet impassioned plea for new attitude and action towards our planet and environment – ‘Care for our Common Home’.  It is adressed not just to Catholics or the wider Christian communion, but to everyone. Immediate comment was almost universally warmly receptive, though tended to focus on particular statements or to extract highlighted ‘soundbites’ from within the lengthy sweep of its 186 pages. But its great strength is to be found in the very breadth and depth that the Encyclical allows itself. Before suggesting changes of political and personal attitude and behaviour, Laudato Si surveys a Biblically-informed theological discussion of science, technology and our responsibility to nature. Since this is also the essential foundation of Faith and Wisdom in Science, I rather think it the task of this column to look hard at the theology of science that the encyclical builds on, before reacting to its recommendations.

The very title of the document, and of course the author’s assumed pontifical name, are both taken from the founder of the movement to which he belongs – St. Francis of Assisi. The endearing honesty of the message is stamped on the introductory pages, which remind us of Francis’ especial love of nature, of all creatures, and the human care to which God entrusts the world. The very language of ‘Brother Sun’ and ‘Sister Earth’ prepares us for the deeply relational thinking that pervades the document, which later (§65 and §66) identifies the vital ‘relationship of human beings to the world’ as a broken one, as damaged as those with our neighbour and with God. The language used of this relationship with the natural world is

The Lord Answering job out of the Whirlwind by William Blake

covenantal and reciprocal throughout. In Faith and Wisdom I found just this astonishingly profound category of relationship to emerge from the Wisdom tradition of the Old Testament – Job, for example, is assured that his anger and suffering, and also his questioning of nature itself, can become a pathway to a time when he is ‘in covenant with the stones’. Biblical affirmation of the goodness of physical reality, and our vital relation to it, really is that strong.

Francis likewise takes a Biblical reading informed by the Wisdom tradition to move away from a naive opposition of science and faith. On the contrary, he draws on science explicitly to inform theology: ‘the best scientific research available today touch[es] us deeply and provide[s] a concrete foundation for the ethical and spiritual itinerary that follows.’ (§15). That itinerary passes, as it did symbolically for Job, and as it does for St. Paul’s reflection on our relation with creation in Romans chapter 8, though a necessary pain: ‘Our goal is not to amass information or to satisfy curiosity, but rather to become painfully aware, to dare to turn what is happening to the world into our own personal suffering and thus to discover what each of us can do about it.’ (§19) If Francis feels pain, and also anger, at the current misshapen framing of that relationship as one of exploitative domination (‘Clearly, the Bible has no place for a tyrannical anthropocentrism unconcerned for other creatures §68), he expresses continual hope that a new and very different approach might follow (‘Instead, our “dominion” over the universe should be understood more properly in the sense of responsible stewardship’ – §116). This is authentic Biblical encounter with the natural world – there is only one place in Old or New Testaments where human relationship with nature is not within the context of pain, and that is within the hope of the new creation (Revelation 22).

The Faith and Wisdom story reaches yet more radical conclusions of our responsibility to use scientific knowledge with wisdom, identifying humans ‘in the image of God’ as participative co-creators in a universe which has not finished the work of creation. This is a vital point – we have the care of something growing and developing, not simply of a finished product. We

are able to harm a future, not just deform a present. Laudato Si draws on a remarkable passage from the celebrated medieval thinker St. Thomas Aquinas to explore and apply this idea. It might even be called a ‘theology of self-assembly! In his Summa Theologica Thomas illustrates the phenomenon of natural emergence: “Nature is nothing other than a certain kind of art, namely God’s art, impressed upon things, whereby those things are moved to a determinate end. It is as if a shipbuilder were able to give timbers the wherewithal to move themselves to take the form of a ship” (§80). The world is pregnant with possibility. I wonder what Thomas would make of today’s theories of self-assembling cell-membranes, an example I used in Faith and Wisdom to illustrate how the apparent chaos of the molecular world is necessary for order and a structure to emerge.

The science and the theology of Laudato Si work powerfully together. Under the surface of its language lie not only the analytic toolkit of science, which informs us of the dominant human causes of global warming, but also the integrative, holistic methods of complexity and the science of systems. The rain-forests are the ‘lungs of the planet’ (§40); A fully interdisciplinary approach is needed to address the ‘deepest problems of the global system’ (§111). Both science and faith create global communities – and an attentive reader will not miss the explicit acknowledgement of reflective contributions from church leaders in Japan, Brazil, New Zealand, Bolivia, USA, Paraguay, Germany, Canada and more. Sufi and Jewish thought is welcomed as well as Christian. This is connectivity embodied as well as urged.

There are of course places where I hesitate to affirm everything Francis says. I rather wish he had said explicitly that science is a gift of God, rather than the one-stage removed ’emerged from the gift of creativity’. But disagreement in some p art will be true of most readers. But living with those differences is also part of living and serving together in a connected and responsible way.

Laudato Si is not only a thoughtful document, it is a beautiful one. It is stern – it needs to be. It is painful. But it is not depressing or despairing. The prayers with which if finishes are full of praise and resurrection hope. It is surely right to suggest a song as we take on the urgent task of mending our ways, rediscovering simplicity, caring for the poor, receiving and using science as God’s gift, and stewarding our world for those who come after us.

Our Latest Scientific Collaborator was a Medieval Bishop

Tom McLeish, Durham University; Giles Gasper, Durham University, and Hannah Smithson, University of Oxford

There was something unusual about our recent research collaboration on the science of light, colours and the perception of rainbows: one member of the team wrote his best science in the 1220s.

The Ordered Universe Project sees humanities scholars and scientists come together to carefully read the 13th century scientific treatises of the English polymath Robert Grosseteste. It was set up in the hope that the work’s technical content might receive a deeper analysis than previous scholarship.

What no one expected was that the scientists in our team would be inspired to do new work as a result. They have ended up becoming co-authors of new scholarly editions of medieval texts. And the humanities scholars among us now also co-author papers in the Proceedings of the Royal Society and other scientific journals.

Grosseteste – “The Greatest Mind You’ve Never Heard of” according to the title of the festival event sponsored by the Arts and Humanities Research Council – lived at an explosive period in the history of thought. He was born in East Anglia of humble origins in the late 12th century. But his studies in Hereford, Oxford and probably Paris enabled him to crest the new intellectual tidal wave surging through the schools and early universities of Europe, triggered by the rediscovery of most of Aristotle’s writings, transmitted by Jewish and Muslim translators and commentators of the previous centuries.

The bright, eager and incisive mind that Grosseteste clearly possessed fed hungrily on this wealth of new material. He was also clearly inspired by the realisation that the human mind can through observation and thought discover structures within the material world that were previously hidden and understand them for the first time.

For example, in his treatise on the rainbow, De iride, he is the first to identify refraction as the phenomenon that produces the rainbow (rather than reflection, as Aristotle thought). Any scientist today would also recognise his articulation of the “aha!” moments we all live for, a phenomenon he calls “sollertia”.

A truly integrated mind

His thinking is, of course, of its own time not of ours. So when he tackles the problem of cosmic origins, the physical problem he sets himself is the creation of a universe with the Earth at its centre, a model we know today to be wrong.

His Christian worldview does inform his thinking, motivating him to argue that the physical origin of the cosmos is a real issue, contradicting Aristotle who proposed a world without any beginning. But for this 13th century bishop (Creationists please note) it is the questions, not the answers, that lie in the book of Genesis.

The result is a highly mathematical and physical “Big Bang” theory of an early expanding universe driven by the force of light, that for the first time unites the Earth, the Moon and the cosmos beyond them under a single physical theory of matter. His formulation gave the team some computational headaches to work through even 800 years later.

His was a truly integrated mind that expected to see the laws of light and matter at work in the cosmos also visible in common objects on Earth. So for Grosseteste, colour is a manifestation of just this. The Ordered Universe team were able to tease out from the 400-word jewel of a treatise De colore (On colour) that he thinks of colours within a three-dimensional abstract space. For Grosseteste, the differences between all possible colours can be captured using variation of just three qualities.

This is remarkable. As there are the three different types of wavelength-selective cone cells in the human retina, colour really does possess a three-dimensional structure (that’s why screens display colours as a mix of red, blue and green).

The appropriate abstract geometry to represent differences between colours is still a question of active research today. The problem was that Grosseteste’s qualities of greatness, clarity and purity had no obvious mapping onto red, green and blue. If only we could have given him a standard colour chart to comment on.

Delightfully, there is such an eternal colour chart: rainbows are the same yesterday as today in all their variations of angle, raindrop sizes and solar illumination. And these three natural “rainbow co-ordinates” are just the ones Grosseteste uses to describe their colour.

After considerable calculation of the spectral features of all possible rainbows, we projected them into a standard 3D perceptual colour space developed by vision scientists in the 20th century. We found that our vision scientist of the 13th century had indeed recognised that rainbows create a way of mapping this space, with the beautiful twist that they generate a new “double-spiral” co-ordinate system for colour-space (see image above).

It feels like a collaboration across the centuries, but the project also affirms the sense that deeply interdisciplinary research takes us into our academic core.

The authors presented their work on Grosseteste at the Cheltenham Science Festival on 7 June 2015.

Is Science Fatally Flawed?

This week’s Faith and Wisdom in Science event took the discussion to the Parish of St. Luke’s Grayshott, where vicar Moray stlukes_home_8Thomas had managed to fill the village social club (excellent beer) with more than a hundred young, old and in-between.  As usual, a very stimulating question-time, including a well-posed challenge to the question of other faith-traditions in the ‘participative-healing’ theology of science.  As that issue has been partially addressed by an ealier post on Islam and Science here, I thought I ought to comment on another challenge, which was put rather differently to others over the past year.

rainbowThe accusation was that the positive view of science as a good gift to be used wisely, but one that really does give us growing insight into the natural world, is fundamentally flawed, that science is permanently doomed to be on the wrong track because of its blinkered purview.  By implication, in this gloomy assessment of science, it can have nothing to do with the Kingdom of God.  It might have someting to do with the deployment of earthly power structures, of the domination of an intelligensia, of a sort of mind-control.  It is most certainly not the the joyous, unexpected wonder that we can, for example, understand the delicate weave of colours in a rainbow, or conjour up on our minds the molecular bonding structure of water in its various forms of ice-crystal.

A New Force

Now it is important not to confuse a view that science is fatally wrong with the simple, everyday, observation that science is wrong about some things most of the time.  The discovery that we can begin to grasp something of, for example, the structure of atoms, is wonderful because it is so difficult.  We can do it, but it takes centuries, many different minds with their own

perspectives, many false starts and wrong-headed ideas, flashes of hopes dashed by decisive experiments, before light dawns.  My questioner conjecured. that science is ignorant of an entire force field that it has ignored, yet which affects, among other things, the structure and properties of water.  This is actually a very instructive example, since there are force fields that untial very recent history were unknown to science. The ‘Weak Nuclear Force’ was first proposed to exist by Enrico Fermi in 1933, and was understood properly as a symmetry-broken aspect of the electro-weak force by Glashow, Salam and Weinberg in 1968.  For many years its existence as a fundamental force field was contested – and its carrying particles, the W and Z bosons were not directly detected until 1983.  Should there be a new force field yet to be discovered, there simply needs to be significant weight of experimental evidence and some form of theoretical concept that allows a predictive approach to further experiments, and what was once outside science will become part of its accepted wisdom.

All you need is love…

So before 1933, and arguably before 1983, science was ignorant of an entire force field.  Did that make it fatally flawed? Was skepticism such as it was within the science community unwarrented suppression of challenging ideas? I argue in Faith and Wisdom in Science that, on the contrary, the weakness and implausibility of young ideas in science needs the exercise of love towards them on the part of their proponents.  The theological insight that our relationship with the natural world is one that starts with ignorance and fear and makes a long and arduous journey towards knowledge and wisdom is well-illustrated by the metaphors of thorns and briars of Genesis chapter 3 and even of the pains of childbirth in Romans chapter 8.  Being wrong does not make science flawed, it is part of the painful journey to understanding that underscores science as the deeply human activity it has always been, and the highest of our imaginative projects.

Can Science be more like Music? An Experiment with Light and Song

The_Light_of_Music_by_TWe4ksmallKarl Popper once wrote: “A great work of music, like a great scientific theory, is a cosmos imposed upon chaos – in its tensions and harmonies in exhaustible even for its creator”. If this is true (and it needs some unpacking before we can get to work on that question) then might great music be a source of illumination of great physics? Might physics inform and deepen our enjoyment of music? I don’t know – but I mean to find out with the help of scientific and musical colleagues in Durham this November, when we set out on a musical and experimental exploration for the International Year of Light.

FaWis_450Of course, musical themes and analogies surface frequently in Faith and Wisdom in Science.  I even imagine a nightmare world, in the introduction, where we have ‘locked away’ music from general human enjoyment and celebration in the same way that we seem to have done with science. Music, of course, has its ‘ladder’ of expertise – with international concert soloists at the top, and most of us somewhere towards the bottom – but nevertheless happily enjoying, and critically engaging with, the production of music in its new writing and performance.  The problem with science is that someone seems to have removed most of the lower rungs of its ladder!  Can we get them back by enjoying science and music together?

Perhaps it was hearing about the idea of the International Year of Light that alerted me to the amount of music, especially choral music, which seems to be inspired by the idea of light. Of course one reason for this is that light itself becomes a metaphor for so much beyond: understanding, hope, creation itself, which in turn inform and inspire music.

Perhaps the ‘classic’ (in every sense of the word) musical moment that captures light-inspiration is the chorus in Hayden’s ‘Creation’ where order bursts out over the composer’s brilliant musical depiction of chaos: “… and … there … was… LIGHT!” – the chorus tip-toes over the introductory words from the Book of Genesis then explode in a cascade of fortissimo harmonies. Shut your eyes and you hear space filled with coruscating colour and brilliance.

But I think that Popper meant more than this by his musings on music. He is talking about form – that essential constraint on imagination that turns inspiration into art. Here he is surely onto something, for in science too we achieve understanding both through powerful imagination (‘could like be like a wave in some sense?’) and severe constraint (‘what happens if I direct a beam though this tiny hole …?). Could it be in this sense that both art and science fashion the order of form and pattern from the chaos of unfettered wild imagination and ignorance – and is it this that makes both music and science so basically human?

We are inviting all comers to an afternoon of hands-on experimental exploration of light from 2pm at Trevelyan College, Durham on Saturday November 14th. Three themes frame the activities – light as a combination of wavelengths and colour, light

as a carrier of information and light and a conveyer of energy for life. It will come as no surprise that we plan to explore the glaring analogy of colour and musical pitch during the afternoon – but we want to go further. Then for one hour from 4pm the Durham Singers will pick up on these same themes in a programme of music from 400 years of history. Two centrepieces to look forward to will be the Bach chorale Jesus, mein Lebens Licht, from the 17th century and a world Premiere of Light by local composer Janet Graham. Graham’s new piece sets words by another North-East artist – poet Gordon Hodgeon, now totally incapacitated by spinal injury, yet still writing. Light carries ‘words’ of information of chemistry and dynamics to us from distant stars. In this piece, Light literally becomes for us the only carrier of the poet’s words, distanced by the light-years of extreme disability. It looks like being a thoughtful and a moving occasion, and also an inspiring one. Come and join us!

Ordered Universe

Easter Week saw the Ordered Universe project team converge for three days on the ancient city of Lincoln – where Robert Grosseteste was Bishop from 1235-1253.  It felt almost like a pilgrimage for those of us who have been studying the scientific works of this 13th

Ceratinly Ordered Universe workshops are increasingly anticipated with a growing sense of academic excitement (What will we uncover together this time? What will I learn about the unfamiliar but intriguing  disciplines that I find an increasing source of wonder?) but increasingly delight at…
