Shakespeare famously asked:

“What a piece of work is a man, how noble in reason, how
infinite in faculties, in form and moving how express and admirable, in action how like an angel, in apprehension how like a god! the beauty of the world, the paragon of animals—and yet, to me, what is this quintessence of dust?

Humans may be complex, capable of great heroism and deep depravity, yet it is worth stopping for a moment to look at the human body and mind to marvel in what we have become, and how we are made.

The visible design of the human body points out common features shared along with other members of the animal kingdom. Examples of these features are: two eyes, two ears, two nostrils, one mouth and four limbs, attached to a body and head. Detailed study of different seen parts of the body may, however, show some differences. For example, the presence of fingers and nails, hair distribution as well as a developed tail. While most members of the animal kingdom have teeth and a tongue, those two could also vary in their number and size, respectively, according to different species. Genetic investigations have shown that we humans share 99 % of our genes with animals, suggesting that our “earthly” component shares a common origin. Indeed, the twenty first century scientific findings match what is written in the Genesis story of creation, a story written over 3,500 years ago, well before genetic sciences came to light.

Creatures great and small

As for morphological differences between animal species, it is difficult to naively conclude why some are wild while others are man-friendly-even if the wild ones have different shapes, design, dietary habits, body size and life span. Other important observed features of the members of the animal kingdom are that they are all born, they all age, then ultimately die.

If we are to look at the unseen features of the members of the animal kingdom, we can again identify similarities. For example, all have a gastrointestinal tract, a cardiovascular system, a reproductive system, a respiratory system, a urinary system and much more. While these systems may differ slightly between species, the overall structure and function achieve similar purposes. For example, heart speed is faster in small animals like rats compared to big ones like elephants who have very slow hearts. Likewise, the respiratory system and the number of respiratory cycles per minute are significantly faster in running animals compared to the sedentary and slowly moving ones. Finally, the number of offspring also differs in different species, being just one at a time in big animals like elephants and horses, and many offspring in small animals like rabbits and mice. Such paradox between the number of offspring and animal size makes you think of the important determining role of the activity of those animals.

Unseen wonders

Now to turn to the rest of the animal kingdom and the unseen features of the human body. To start, let us look at the amazing functions of the human brain and its various functions. When humanity is sometimes described as the crown of creation, such a description is based on the superiority of human brain function and skills. Its sophisticated structure and how vital centres are created deep in the skull, to be protected from traumas, make you marvel. Also, the brain controls the different functions of the whole body, with its sensory and motor activities, various vital system functions including the lungs and the heart, all endocrine glands’ function, in addition to various receptors and centres that allow utmost precision and accuracy in everything we do. An example of this kind of precision is a doctor feeling a vein or an artery with the tip of a finger to insert a needle or a musician moving a finger a few millimetres while playing a violin, to produce the exact sound needed. Furthermore, the integrated function of human muscles, nerves and spinal cord is also amazing, let alone the synapsis between the nerve endings and muscle bundles, the chemicals secreted in them which allow electric stimulus transmission from the nervous system to achieve the motor function and desired movement.

The human brain also has the unique feature of storing knowledge. Of course, we should not ignore the importance of the training and programming ability of human brain. We learn how to drive a car, how to play games, how to study, how to operate safely on a sick patient. Such acquired skills are quite limited in other members of the animal kingdom. Moreover, the human brain has the unique ability to invent, discover, improve and correct errors it identifies.

Another very unique feature of human brain is its ability to conduct speech, a feature of humans that is under-developed in other members of the animal kingdom. While most animals can make noise and sounds, only humans can articulate words, sentences and even sing very complex songs. This unique ability seems to be the underlying mechanism behind the development of languages which are based on the human ability to talk and transmit information and knowledge by words and phrases.

The unseen brain has allowed human life to develop over time, building skills and achievements from generation to generation. Millennia ago, humans lived in huts together with animals, and now they build houses and palaces to live in. Centuries ago, we used donkeys, horses and camels to travel but now we use cars, trains, ships and airplanes. Our ancestors burned wood and coal to cook and to warm but now we use electricity to do these.

When we look carefully at the unseen parts of the human body, we also realize that we cannot alter any of it, despite the scientific advances made over the years. We can understand what harms our body and take measures to avoid it. Out of the ability of our brain to discover and invent, we have now produced science-based means for curing various diseases. Consider how we can replace a dysfunctional heart valve or a mobility-limiting joint. These inventions have resulted in a better quality of life, alleviating of symptoms, even helping to avoid early death, in some cases such as heart disease and cancer.

The heart of the matter

Another unseen source of life in humans is the heart. This fist-size organ is so complex in its structure and function. Recent scientific advances have enabled us to study heart function in milliseconds, hence the development of pacemaker treatments. They have also allowed clear imaging of the inside of the heart and the identification of pathologies, developments that guide practitioners to the optimum treatment of heart conditions. Recent discoveries have also allowed us to better understand how people develop coronary artery disease and how the pathology starts at the innermost layer of the arteries, particularly in individuals carrying significant risks for atherosclerosis including, smoking, high blood pressure, diabetes, high cholesterol and obesity. Amazingly, obesity has been shown to be the strongest underlying cause of other risk factors, hypertension, diabetes and hypercholesterolemia. So, nature cannot be blamed in many of these patients but our own patterns of behaviour. Science has shown that walking at least 5,000 steps each day, complying with the design of our body, reduces the likelihood of developing coronary artery disease by 15 per cent.

The unseen physiology of the rest of our body systems and the interaction between systems make us wonder how we are made. A rise of our body temperature by one degree due to a bug infection affects all body systems from the brain to the heart. A virus which cannot be seen by the most powerful microscope can destroy our lungs and cause premature death, as was the case with COVID-19 and others.

Finally, human inventions in the form of powerful microscopes have allowed scientists to study the human cell, which is the smallest living component of our body. Such small cells cannot be replicated in any factory in the twenty-first century, despite the vast scientific developments that surround us. You'll be surprised to learn how complicated and meticulously fine-tuned a human cell is and also how it functions, connects with other cells and other parts of the body. An example of this is the interaction between body minerals, calcium, sodium and potassium with heart and muscle individual cells. Such a function is critically controlled by many factors such as time, electric stimulation and pressure differences producing remarkably harmonious contractions and relaxation of the muscles without missing a beat.

The bells that awaken awe in the new year

We need new rhythms if we are to navigate the world as it is today.

Elizabeth Wainwright

Elizabeth Wainwright is a writer, coach and walking guide. She's a former district councillor and has a background in international development.

Restored church bells lined up in a cathedral, as crowds mill around them.

Notre Dame bells.

Notre Dame de Paris.

The jackdaws flap and caw as they come in to roost. The sun sets behind the bare trees; its fiery farewell doing nothing to warm the cold air. The village church bell rings out 4pm. My young daughter stops what she is doing, says “ding dong”, then carries on. That’s what we all used to do: stop what we were doing and be called to something else, the bell’s rhythmic tolls cutting through our individuality and unifying us for a time. Perhaps we would go to church, or stop to pray, or remember the dead for whom the bell tolled. I have been thinking about that often-quoted poem by John Donne:

No man is an island,

Entire of itself.

Each is a piece of the continent,

A part of the main.

If a clod be washed away by the sea,

Europe is the less.

As well as if a promontory were.

As well as if a manor of thine own

Or of thine friend's were.

Each man's death diminishes me,

For I am involved in mankind.

Therefore, send not to know

For whom the bell tolls,

It tolls for thee.

Now, church bells ring out the hours of the clock, and occasionally still ring out mourning and celebration too. They seem also to ring out a quaintness, a nostalgia, a past that is slipping away. I have been sitting by the old stone church listening to them, wondering what else they might be tolling for, what else might be slipping away. In Donne’s poem, he says the bell tolls not for them, but for us, because we are all connected. Each person’s death diminishes the whole from which they were a part, and so diminishes me. The bells used to remind us of that whole.

The bell could be melancholy but I notice how it tilts me toward hope, even in this deep winter stillness; an audible distillation of light ringing through the dimness. I think it is the hope of mankind which Donne tells me I am involved in. These old bells seem to ring defiantly despite the many other chimes that ring just for me: digital pings, messages, notifications, news, an algorithm that tried to force me down my own lone path. But echoes of communal life persist. Now, I hear the bell say:

Ding: listen

Dong: lift your head

Ding: look

Dong: life is a whole

Ding: face each other

Dong: this is the only way we will meet the future

A few days later, my daughter and I step into the village hall. We surface together from evening darkness into the light of song: it is the carol concert, we are late, and the music is about to start. The singers are decked in lights and earthy greens and rusty reds. They are a group from Exmoor who conserve and share traditional and local songs, as well as singing the songs we all recognise. My daughter’s cheeks are pink, her eyes blaze with delight. In a few days, the solstice will be here, and the earth will pause in its movement before turning back to face the light. Here in this old hall, the songs seem to reach towards that coming light: we are here, we are together, and we choose to lift our individual voices as one chorus of community.

I think about the people in this hall gathering to mark other things — memories, celebrations, vision, care — and I wonder about the more figurative bells that draw them together to do so. What are the bells that keep us together now, when so much encourages us into isolation and individualism? — The bells that remind us we can never be the islands that we are so often encouraged to be: independent, tough, believing consumption will heal us, packaged into a personal brand; everything encouraging us to be seen, not known.

I try to listen for these bells, to hear how to inhabit time reverently and with reciprocity, not with urgency and isolation. In many places the actual church bells are silent, but I think we still need the bells of communality: bells that call us into share rhythms, reminding us to pause in our individual movement, reminding us to gather, to mourn, to remember things and find the light and the hope in each other, just as the tilting of the earth pauses at the solstice before it turns to face the light.

Nature’s cycle is one way of doing this: tuning in to the turn of the year that makes new life possible. The solstice and equinox; wassailing in January to bless the apple trees; noticing when migrating birds appear or leave; sharing planting and harvesting days. Liturgical calendars are a way that Christian communities kept and still keep time: advent, Christmas, lent, Easter. These rhythms become familiar, reminding us that time isn’t linear, much as the myth of infinite progress would have us believe otherwise. Time is cyclical, expanding and contracting; old events revisited regularly in new ways.

Knowing that it is not just me looking at these stars, but people across the world and through time, brings me into a peace, a reverence that can be hard to come by.

And there are other things that can bring us together too: causes, hobbies, interests, protests. These can take on the role of bells perhaps, drawing us together around shared purpose – but shared purpose and shared existence, shared being, are not always the same thing.

Perhaps we need new rhythms if we are to meet the world as it is today. Imagine if a bell tolled — literally or figuratively — not just for human funerals, but whenever a species went extinct, or a tree cut down. Imagine if neighbourhoods gathered to light candles and share stories and soul and care each week, offering a space that church used to provide to lots of people through the ages. And what if we resurrected old traditions for a new age: ‘beating the bounds’ as a way to mark not just the boundaries of land but the places that need restoring and regenerating now; harvest festivals not just as something for school children and rural churches, but as a way we can better connect with food and farming. What if we looked at old wisdom; the way the church calendar aligned with the farming calendar, asking us to remember that food and the soil it comes from are sacred things.

Our friends were near the beach in Costa Rica. They noticed that at the end of the day, everyone stopped what they were doing — fishing, fixing, working — and watched the sunset. This moment of beauty seemed to bring people together into synchronicity. In his book Awe: The Transformative Power of Everyday Wonder, scientist Dacher Keltner shows us how experiencing awe can, amongst other things, help us to experience humanity, see patterns in life, and better collaborate with each other. He says: “The last pillar of the default self—striving for competitive advantage, registered in a stinginess toward giving away possessions and time—crumbles during awe. Awe awakens the better angels of our nature.” Perhaps putting ourselves in the way of awe might help us hear the bells — old and new — that ring in this current age, and that might bring us together and love each other well. If love only exists in relationship, and love is what helps us to see and to care, then protecting and restoring relationship seems to be vital work for our time.

Now, the winter sky is dark and the stars shine brightly above. They shine with a clarity that matches the peal of the bells in the village. They call me beyond myself into something unified, something older, something necessary. They call me into wonder and awe. Knowing that it is not just me looking at these stars, but people across the world and through time, brings me into a peace, a reverence that can be hard to come by. I step back into the house but my mind faces outwards into the world.

Church bells used to call people together to worship, bringing a sense of shared time and purpose. They still ring, but they can be hard to hear against the noise of individual time. I think they are calling us together again now. And if we can’t hear them, perhaps we need to set new bells ringing. May the bells that ring this New Year’s Day inspire us to do so.
