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.

Can life go on after wicked acts of violence?

We can fulfill the law in more ways that just the legal sense.

It’s an all too human instinct to seek vengeance against psychopathic killers, especially those murderers of children and youngsters. If we’re honest, we can all feel a primal urge to “get our hands on them”, to inflict, in retribution, the pain, death and suffering that they delivered on their victims and their families.

That must be why, shortly after his sentencing, the murderer of the three little girls at a dance class in Southport - Elsie Dot Stancombe, Alice da Silva Aguiar, Bebe King – was reported to have been beaten to a pulp by fellow prisoners. It went momentarily viral with the help of the likes of former support-actor Laurence Fox, who writes in short sentences because he thinks in them, claiming he’d heard it “on the grapevine”.

The story was only slightly undermined by such giants of investigative reporting getting the jail where the convicted prisoner is incarcerated entirely wrong.

It’s a kind of wishful thinking, if a herd can be said to think. It’s also why we have a rule of law in what we aspire to call a civilised country. It’s there to bring such perpetrators to justice, while ensuring that justice isn’t impaired by the wholly understandable desire of victims’ families to tear their killers to pieces and the knuckle-dragging, social-media lynch mob who think they know what justice looks like.

Hard for anyone to know how to respond to this. It’s perhaps particularly challenging, for fear of being intrusive and trite, to see how a religious faith can respond. But I want to have a go. And to avoid those charges of hand-wringing solipsism, I won’t speak of hope and love and life in this context, which so often feels like throwing a handful of seeds into a raging storm.

Rather, I think I want to ask what fulfilment of the law might look like. The full 240-page report into the killing In Nottingham in June 2023 by a paranoid schizophrenic of two 19-year-old students, Barnaby Webber and Grace O’Malley-Kumar, and separately a 65-year-old man, Ian Coates, has been published. Not unnaturally, the headline theme has been that the killer “got away with murder” through a series of chaotic failings by the NHS, in its discharges of its patient into the community, in its absent risk management and failures to medicate him adequately.

Culpability for these crimes is a powerful driving force. But there’s something else going on here. After the report’s publication, the two young victims’ mothers, Sinead O’Malley-Kumar and Emma Webber, went on BBC Radio 4’s Woman’s Hour for an extended interview. And, yes, of course they share a campaigning spirit to change the health system so that this kind of tragedy is less likely to happen again. But Emma said that they’re “not witch-hunting with pitchforks” and Sinead observed with crystal clarity that “systems are made up of people”. This was about human as well as systemic change.

The go-to journalistic word here is “dignity” and, yes, these two mothers have it in bucket-loads. But, as I say, there’s something else. Struggling to identify it, I come up with the phrase that life goes on – and not in its platitudinous sense of bucking up and getting on with what’s left to us. There’s a feeling of continuation, not just of ending, dreadful as those endings are for families.

Asked by interviewer Anita Rani (who, in passing, was first class) what sustained them, where their strength came from, Emma answered in a heartbeat “Barnaby”, adding quickly in a heartbreaking throwaway: “It’s that invisible umbilical cord.” Similarly, Sinead said she was strengthened on a “bad day” by the knowledge that she was “doing it for Grace.”

They know, absolutely, that they can’t change what happened, but they’re there for each other. And not just these two mothers. Bereaved parents from Southport have been in touch, as they said, in “awful solidarity.”

A solidarity unconfined to this dreadful cadre of the violently bereaved. When these two mothers visited Nottingham for a vigil for their lost children, they expected “maybe 50” to turn up. In the event, there were “thousands and thousands” in Market Square. One of the two said simply: “There’s more good than bad out there.” Life goes on. Again, not in the sense of pulling your boots up and making the best of it, but in the sense of acknowledging that this is not all there is, that we’re working towards something infinitely better.

I think that’s what fulfilling the law might mean. Not solely changes to human systems, but changes in humanity. And perhaps that makes some sense of the gospel line: “I’m come not to destroy the law, but to fulfil it.” Not just to fulfil prophecy; not just to improve legal processes, but to fulfil the immutable laws of humanity for which these two mothers – and so many others around them – work so tirelessly.
