St Kilda: sketching sanctuary and struggle

A remote Scottish island’s many meanings catch an artist’s eye.

Alastair Gordon is co-founder of Morphē Arts, a painter and art tutor at Leith School of Art. He works from his studio in London and exhibits across the UK, Europe and the US.

Sketching on St Kilda.

Nestled amidst the tempestuous waters of the North Atlantic Ocean, the islands of St Kilda stand as a testament to isolation unparalleled in the British Isles. Located miles out from the Scottish mainland, the islands form an archipelago that rises defiantly, resembling a fortress of solitude amidst the tumultuous waves. 

In 1930, the islanders made a heartfelt plea to be evacuated from their beloved home, as the challenges of survival had become insurmountable. This marked the poignant conclusion of a remarkable two thousand years of human existence on the islands and no permanent community has been established since. Presently, St Kilda stands as a wild and desolate terrain, teeming with a diverse array of wildlife. Amongst the rugged slopes, one can witness the unexpected presence of wild sheep, descendants of the original livestock once cared for by the community. Following the evacuation, the sheep were left to roam freely, adapting to their newfound freedom. Isolated from the outside world for countless centuries, the islands have even given rise to their own unique subspecies of mouse and wren, a testament to the extraordinary resilience of life in this remote haven. 

It took me three arduous attempts, spread across consecutive years, to finally set foot on the elusive Hirta, the main island in a cluster of islets and sea stacks known collectively as St Kilda. Access to this remote wilderness is only granted during the warmer months, and my previous endeavours had been thwarted by relentless bouts of stormy weather. However, these failed attempts only served to intensify my determination, turning the eventual arrival into a pilgrimage of sorts, where the sweet taste of success was amplified by the challenges overcome. 

Standing at the water's edge, I found myself contemplating the concept of an island as a unique form of solitude, a refuge or retreat, perhaps even a hermitage or prison. 

As St Kilda emerged on the horizon, it appeared like a jagged tooth or a mystical axis mundi, a place where the earthly and spiritual realms intersect. Despite its wild and untamed nature, the island is paradoxically dominated by the imposing presence of the Ministry of Defence. Strange listening devices and radars loom over the cliff tops, as if engaged in a silent conversation with the world beyond. Stories of St Kilda often carry an air of romanticism, but the reality of island life was harsh and unforgiving. 

As our boat ventured into the circular embrace of St Kilda, a sudden stillness descended upon the waters, transforming the surroundings into an idyllic oasis of tranquillity. The island, formed from the remnants of a volcanic eruption, boasts a natural harbour in the shape of a perfect circle, its walls rising like a majestic amphitheatre to a towering height of 426 metres, equivalent to the Empire State Building, before plunging abruptly into a sheer drop.  

The village, consisting of a single street lined with stone cottages known as Black Houses, was the epicentre of island life. Daily existence revolved around the rhythms of fishing, agriculture, and church. Each morning, the island parliament convened to allocate the day's tasks, which often involved harvesting birds, tending to livestock, and repairing nets. Every year, the men of the island would scale the treacherous cliffs with nothing more than homemade ropes to gather the young birds from their precarious nests, while their protective parents swooped and dived in an attempt to thwart such pillaging. Winters were harsh, and the traditions of the church were strict. Missionaries were sent to the island to minister to the faithful, imposing a rigid routine of spiritual disciplines that seemed to serve as both law and religion.  

Upon reaching the shore, we were greeted by the island steward, one of only two current inhabitants of the island and resident only in the warmer months. Unless, of course, one counts the Ministry of Defence, whose enigmatic presence permeates every corner of the island. Their satellite dishes and listening posts loom ominously, as if engaged in some clandestine communication with an unseen realm, shattering the illusion of complete wilderness.  

Standing at the water's edge, I found myself contemplating the concept of an island as a unique form of solitude, a refuge or retreat, perhaps even a hermitage or prison. It brought to mind the image of Superman in his fortress of solitude or Edmond Dantès, a victim of misfortune, imprisoned and abandoned until the idea of the Count allowed for a rebirth. 

But deep down, I knew that this fantasy was far from the brutal reality faced by those who eked out a living on the edge of the world 

As a child, I often sought solace on islands during family holidays. There was something about the encircling presence of land surrounded by water that evoked a sense of tranquillity, a sanctuary away from the worries of the world. A sacred space where a weary soul could commune with the divine.  

As I ascended the steep walls of Hirta, my camera in hand and sketchbook tucked under my arm, I couldn't help but feel a sense of purpose. I felt like one of those Romantic painters of the previous century who attempted to bring a taste of the natural sublime to the city dwellers, trapped in their concrete jungles and smog-filled air. In that moment, I released mine is not the task of modern-day Romantic painter, venturing into the wilderness to capture moments of awe-inspiring beauty but to chronicle the mundane moments of domestic sublime as witnessed by this landscape through centuries of human inhabitation. The images I captured and the sketches I made now form the basis of new paintings to feature in an upcoming exhibition at An Lanntair gallery in Stornoway.  

But as I continued my climb, I couldn't help but question the romantic notions that had fuelled my journey. The landscape itself remained indifferent to my perception of it. It cared not for the grand narratives I projected onto its rugged terrain. It simply existed, unyielding and unapologetic. 

And what of St Kilda? Was it truly an idyllic haven, shielded from the political and ecological pollutants of the outside world? Or was it a fortress of solitude, where harsh regimes and a cruel climate ruled? Perhaps it was an oxymoron, embodying both extremes simultaneously. 

As our boat sailed away from the island, I found myself pondering the reality of life on St Kilda. What was it truly like to inhabit such a remote place? At times, I allowed my imagination to wander, envisioning a utopia where crime was unheard of, where the absence of policing was a testament to the inherent goodness of humanity. But deep down, I knew that this fantasy was far from the brutal reality faced by those who eked out a living on the edge of the world. Life on St Kilda must have been a constant struggle, a battle against the elements, made bearable only by the flickering hope of a better future. 

As I packed away my camera and sketchbook, I couldn't help but feel a sense of gratitude for the opportunity to glimpse into the past, to touch the remnants of a forgotten world. The exhibition I will present in Stornoway will be more than just a collection of art; it will be a tribute to the resilience of the islanders, not just in St Kilda but across the Outer Hebrides in times of hardship, to their ability to find beauty and hope in the harshest of circumstances. And as I prepare to share their story again through painting, I hope that it will serve as a reminder of the fragility and strength of the human spirit, even in the face of isolation and adversity. 

 

Alastair Gordon is an artist based in Edinburgh and London. His new exhibition of paintings opens at An Lanntair in Stornoway, Isle of Lewis, 31 May 2024. The exhibition coincides with a parallel two-person exhibition with Elaine Woo MacGregor opening the same night at Cynthia Corbett Gallery, London.

Ethics needs to catch-up with genetic innovation

Are we morally obliged to genetically edit?

It makes me feel very old when I realise that Louise Brown, the first baby to be born via in vitro fertilisation (IVF), will be 47 years old on July 25th this year. Since her birth in 1978, over 10 million IVF-conceived babies have been born worldwide, of whom about 400,000 have been in the UK. Over that period, success rates have increased such that in some clinics, about 50 per cent of IVF cycles lead to a live birth. At the same time, there have also been significant advances in genetics, genomics and stem cell biology all of which, in relation to human embryos, raise interesting and sometimes challenging ethical issues. 

I start with a question: what is the ‘moral status’ of the early human embryo? Whether the embryo arises by normal fertilisation after sexual intercourse or by IVF, there is a phase of a few days during which the embryo is undergoing the earliest stages of development but has not yet implanted into the wall of the uterus; the prospective mother is not yet pregnant. In UK law, based on the Human Fertilisation and Embryology Act (1990), these early embryos are not regarded as human persons but nevertheless should be treated with some respect. Nevertheless, there are some who oppose this view and believe that from the ‘moment of conception’ (there actually isn’t such a thing – fertilisation takes several hours) embryos should be treated as persons. In ‘conventional’ IVF this debate is especially relevant to the spare embryos that are generated during each IVF cycle and which are stored, deep-frozen, in increasing numbers for possible use in the future.  

A further dimension was added to this area of debate when it became possible to test IVF embryos for the presence of genetic mutations that cause disease. This process is called pre-implantation genetic diagnosis and enables prospective parents who are at known risk of passing on a deleterious mutation to avoid having a child who possesses that mutation. But what about the embryos that are rejected? They are usually discarded or destroyed but some are used in research. However, those who hold a very conservative view of the status of the early embryo will ask what right we have to discard/destroy an embryo because it has the ‘wrong genes’. And even for the many who hold a less conservative view, there are still several questions which remain, including ‘which genetic variants we should be allowed to select against?; should we allow positive selection for genes known to promote health in some way?’; should we allow selection for non-therapeutic reasons, for example, sporting prowess?’ These questions will not go away and there are already indications that non-therapeutic selection is being offered in a small number of countries. 

Genetic modification 

This leads us on to think about altering human genes. Initially, the issue was genetic modification (GM) which in general involves adding genes. GM techniques have been used very successfully in curing several conditions, including congenital severe immune deficiency and as part of treatment programmes for certain very difficult childhood cancers. One key feature of these examples is that the genetic change is not passed on to the next generation – it just involves the body of someone who has already been born. Thus, we call them somatic genetic changes (from the Greek, sōmatikos, meaning ‘of the body’).  

Genetic modification which is passed on to the next generation is called germline GM which means that the genetic change must get into the ‘germ cells’, i.e., the sperm or egg. Currently, the only feasible way of doing this is to carry out the genetic modification on the very early embryo. At present however, with just one very specific exception, GM of human embryos is forbidden in all the countries where it would be possible to do it. There is firstly the question of deciding whether it is right to change the genetic makeup of a future human being in such a way that the change is passed to succeeding generations. Secondly, there are concerns about the long-term safety of the procedure. Although it would involve adding specific genes with known effects, the complexity of genetic regulation and gene interactions during human development means that scientist are concerned about the risks of unforeseen effects. And thirdly, germline GM emphasises dramatically the possibility of using GM for enhancement rather than for medical reasons.  

Genome editing 

This leads us to think about genome editing. In 2011, it was shown that a bacterial system which edits the genomes of invading viruses could also work in other organisms This opened up a large array of applications in research, agriculture and medicine. However, the ethical issues raised by genome editing are, in essence, the same as raised by GM and so there is still a universal prohibition of using the technique with human embryos: germline genome editing is forbidden. Despite this, a Chinese medical scientist, He Jiankui, announced in 2018 that he had edited the genomes of several embryos, making them resistant to HIV; two babies with edited genomes had already been born while several more were on the way. The announcement caused outrage across the world, including in China itself. He Jiankui was removed from his job and then, after a trial, was imprisoned for three years; his two colleagues who collaborated in this work received shorter sentences. 

At present the universal prohibition of human germline genome editing remains in place. However, the discussion has been re-opened in a paper by an Anglo-Australian group.  They suggest that we need to develop heritable (i.e. germline) polygenic genome editing in order to reduce significantly an individual's risk of developing degenerative diseases. These includecoronary artery disease, Alzheimer’s disease, major depressive disorder, diabetes and schizophrenia. I note in passing that one of the authors is Julian Savulescu at Oxford who is already well-known for his view that parents who are able to do so, are ‘morally obliged’ to seek to have genetically enhanced children, whether by PGD, GM or genome editing. The use of polygenic editing, which would, in all likelihood, be available only to the (wealthy) few, fits in well with his overall ethical position. Needless to say, the paper, published in the prestigious journal Nature, attracted a lot of attention in the world of medical genetics. It was not however, universally welcomed – far from it. Another international group of medical scientists and ethicists has stated that ‘Human embryo editing against disease is unsafe and unproven …’ and even go as far as to suggest that the technology is ‘… going to be taken up by people who are pushing a eugenics agenda …’ remain very pertinent. 

Harder still and harder 

I have no doubt that amongst different reader there will be a range of opinions about the topics discussed so far. For anyone who is Christian (or indeed an adherent of almost any religious faith), one of the difficulties is that modern science, technology and medicine have thrown up ethical questions that could not have even been dreamed of by the writers of the Bible (or of other religious texts). We just have to use our wisdom, knowledge and general moral compass (and for some, prayer) to try to reach a decision. And if what I have already written makes that difficult, some recent developments multiply that difficulty still more.  

In the early years of this century, scientists developed methods of transforming a range of human cells into ‘pluripotent’ stem cells, i.e., cells capable of growing into a wide range of cell types. It also became possible to get both induced stem cells and natural stem cells to develop into functional differentiated cells corresponding to specific body tissues. This has huge potential for repairing damaged organs. However, other applications are potentially much more controversial. In 2023, Cambridge scientists reported that they had used stem cells to create synthetic mouse embryos which progressed at least as far as brain and heart formation within the normal pattern of mouse embryo development. 

At about the same time, the Cambridge group used individual human embryonic stem cells (from the blastocyst stage of embryonic development), to ‘grow’ early human embryos in the lab. There is no intention to use these embryos to start a pregnancy – indeed, it would be illegal to do so – but instead to study a period of embryo development which is not permitted with ‘real’ human embryos (research must not continue past 14 days of development). But how should we regard synthetic embryos? What is their moral status? For those who hold a conservative view of the normal human embryo (see earlier), should we regard these synthetic embryos as persons? Neither does the law help us. The legal frameworks covering in vitro fertilisation and early embryos (Human Fertilisation and Embryology Acts, 1990, 2008) do not cover artificial embryos – they were unknown at the times the legislation was drawn up. Indeed, synthetic embryos/embryo models are, in law, not actually embryos, however much they look like/behave like early embryos. Earlier this month, the Human Fertilisation and Embryology Authority (HFEA) discussed these developments with a view to recommending new legislation, but this will not dispel an unease felt by some people, including the science correspondent of The Daily Telegraph, who wrote that this research is irresponsible.  

But there is more. In addition to synthetic embryos, the HFEA also discussed, the possible use of gametes – eggs and sperm – grown from somatic stem cells (e.g., from skin) in the lab. Some authors have suggested that the production of gametes in vitro is the ‘Holy Grail’ of fertility research. I am not so sure about that but it is clear that a lot of effort is going into this research. Success so far is limited to the birth of several baby mice, ‘conceived’ via lab-grown eggs and normal sperm. Nevertheless, it is predicted that lab-grown human eggs and sperm will be available within a decade. Indeed, several clinicians have suggested that these ‘IVGs’ (in vitro gametes) seem destined to become “a routine part of clinical practice”.  

The lab-grown gametes would be used in otherwise normal IVF procedures, the only novelty being the ‘history’ of the eggs and/or sperm. Clinicians have suggested that this could help couples in which one or both were unable to produce the relevant gamete, but who still wanted to have children. In this application, the use of IVGs poses no new ethical questions although we may be concerned about the possibility of the gametes carrying new genetic mutations. However, some of the more wide-ranging scenarios do at the least make us to stop and think. For example, it would be possible for a same-sex couple to have a child with both of them being a genetic parent (obviously for males, this would also involve a surrogate mother). More extremely, a person could have a child of which he or she was actually, in strictly genetic terms, both the ‘father’ and the ‘mother’. What are we to make of this? Where are our limits?  

Dr Christopher Wild, former director of International Agency for Research on Cancer, explores in depth many of the developments and issue I outlined above. His article on why a theology of embryos is needed, is clear, well-written, helpful and thought-provoking.
