The heart of the matter

Heart doctor Michael Henein steps back to consider the unseen and unique wonders of the human body’s design.

Professor Michael Henein is a consultant cardiologist, and a Professor of Cardiology at Umea University, Sweden.

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 country needs fixing, here’s where to start

Turning back the clock, closing the gates, and putting up more flags, is not the answer

This is the third in a series of articles clustered around the ideas of constitutionalism, Christianity and national identity. The first article set out the case for a new written constitution in order to protect against the authoritarian reactionary populism that threatens to undermine democratic norms and institutions. The second article made a distinction between England’s ‘metaphysical’ constitution and its ‘mechanical’ constitution – arguing that the former is in need of restoration, and the latter in need of thorough reform.  

This article concludes with a plea for peace and unity. There is not much, in this increasingly febrile and polarised political climate, that left and right agree upon. Who is responsible for the mess we are in: the Romanians or the Etonians? Against whom should we direct our ire: the people in small boats in the Channel, or the people in big yachts in the Cayman Islands? Was Thatcher a hero or a villain? Was the purity of Brexit bliss betrayed by scheming Remoaners, or was leaving the European Union always going to be a disaster? 

What we can agree upon, however, is that something is deeply broken. While we might disagree on the causes and the solutions, the unavoidable evidence of brokenness is before our eyes. In every area of daily life, things are – to use the most fitting vernacular expression – ‘a bit pants’. Perhaps things are not utterly dire, in the way that much of somewhere like Sudan or Burma is utterly dire, but they are nevertheless far from the standard that one might reasonably expect from the rich, first world, country we still claim to be.  

Park life 

Go, for example, to your local park, if there is one. Observe the broken glass, the graffiti, the used condoms, the discarded drug paraphernalia, the joyless air of bleak menace in a place that should be a happy sanctuary for children and families. If that description does not match your experience, perhaps you are one of the lucky ones, who lives in a good area – but many of your fellows, in dull decaying provincial towns, are much less fortunate.  

Parks are just one manifestation of a land in the doldrums. One might just as well point to the fact that since privatisation water companies have not built any new reservoirs, or to uncollected rubbish piling up in the streets of Birmingham, or to the difficulty of getting an NHS dental appointment. Everything is tired, run down, threadbare, falling apart.  

Those in charge, nationally and locally, are stretched between the irreconcilable demands of expanding needs and tight budgets. Engulfed by short-term crisis-management, they lack the ability to look up, grab the situation by the horns, and bring about the fundamental, structural and systematic change that is needed to actually fix things.  

The decay is evident, too, in society at large. Employment, for those who can get it, is characterised by low wages and precarity. Housing costs are absurd. People at all levels have become exhausted, demoralised, bored and lacklustre, locked in an ‘overwhelm paralysis’. The public mood has become despondent, cynical, ineffectually angry, but also frightened. Many are grimly hanging on, just going through the motions to the minimal extent necessary to endure the week, and afford the month. Even basic civility and politeness have worn thin.  

This is a far cry from a ‘Land of hope and glory’. Indeed, if one were to take honest stock of things, one might conclude that we live in a state where there is none righteous, and where all have sinned and fallen short of the glory of God.  

Cobwebbed constitution 

In making this sudden metaphysical turn – jumping from the decay, despondency and desperation evident around us, to the realm of the spirit – I do not wish for a moment to minimise the importance of such mundane human affairs as ideologies and policies. What government does and does not do, and what law allows or prohibits, matters. It should be no surprise that if governments leave undone those things which they ought to have done, and do those things which they ought not to have done, then there will be, at the end, ‘no health in us’.  

Still less would I wish to neglect the role of institutions and structures – and, ultimately, the constitution itself. The woes we experience, in terms of bad policy and poor execution, are largely the result of an ill-constituted state. The words of Tom Paine (a man ill-remembered by history, but one of the few Englishmen to have understood the centrality of constitutional matters) are as true today as when he penned them more than two centuries ago:  

‘For want of a constitution in England to restrain and regulate the wild impulse of power, many of the laws are irrational and tyrannical, and the administration of them vague and problematical.’  

When it comes to mending a country in decline, the first thing to do is to make sure the constitution is sound, and that the institutions of democracy and governance work as they should. Behind all the policy and governance failures, of both Conservatives and Labour, lies the fact that we are governed by the cobwebbed remains of a once mighty commercial imperial state, now hollowed out by neoliberalism, without any clear ethical principles to direct or sustain it. To expect good outcomes from such an ill-constituted state would be as absurd as expecting to gather figs from thorns, or grapes from briers. 

We might even put it in these terms: Every good constitution brings forth good government; but a corrupt constitution brings forth evil government. A good constitution cannot bring forth evil government, neither can a corrupt constitution bring forth good government. 

Constitutional renovation has therefore become a precondition for the restoration of the legitimacy, credibility, authority, and moral integrity of the state, as well as for the health, well-being, and prosperity of the people. This calls for quite a different project of national renewal from that offered by offered by the parties of the reactionary right. Simply turning back the clock, closing the gates, and putting up more flags, is not the answer.  

Governo largo 

The centrepiece of a national renewal project should be constitutional: to create a truly ‘public state’ – a democratic state founded upon, oriented towards, and capable of serving, the common good. Tend to that tree, water its constitutional roots, and the fruits will follow.  

Again, Paine tells us what the fruits of that good tree are, and therefore how to recognise when the constitutional tree is healthy:  

‘When it shall be said in any country in the world, my poor are happy; neither ignorance nor distress is to be found among them; my jails are empty of prisoners, my streets of beggars; the aged are not in want, the taxes are not oppressive; the rational world is my friend, because I am the friend of its happiness: when these things can be said, then may that country boast its constitution and its government.’ 

This is little more than a restatement of the basic Aristotelean distinction between good and bad government. Good government (the well-constituted state, or ‘polity’) governs in the public interest, for the common good, while all forms of bad government – tyranny, oligarchy and populism – govern in the private interests of the rulers, perverting public power for personal gain. 

The renaissance Italian statesman, Francesco Guicciardini, highlighted this distinction in clearer, more binary terms. He contrasted the ‘governo largo’ with the ‘governo stretto’. A governo largo is a wide, open, broad-based government, in which power is broadly shared and publicly accountable, so that public life is centred upon public needs. It is system of government not only by and of the people, but also for the people. ‘Governo stretto’, in contrast, is a narrow, restricted, closed, private, self-seeking, public-ignoring state. 

The first attempt at constituting a ‘governo largo’ in England was made during the Civil Wars, with the ‘Agreement of the People’. This went through several drafts between 1647 and 1649. The title was well chosen. Real, working, constitutions are produced through a process of discussion and negotiation – ‘arguing and bargaining’ – that enables a broadly acceptable constitutional settlement to be reached. The constitution expresses what been agreed, amongst the people or their representatives, as the common foundation of the state.  

Reaching such an agreement today, in a society that has become as polarised and divided as ours, will not be easy. It is nevertheless necessary. In order to establish a state that serves the common good, we must have some agreed foundations, ground-rules, shared principles, upon which a general consensus exists. This alone can provide the basis for an inclusive, publicly-oriented, ‘governo largo’.  

This is not a radical innovation. Almost every country which has become independent from the British Empire has adopted a democratic constitution as its supreme and fundamental law. In some cases – in India in 1950, South Africa in 1996, and Kenya in 2010 – a serious attempt was made to establish an inclusive ‘governo largo’ constitution. In so doing, they sought to heal deep divisions, to reach a broadly acceptable settlement, and thereby to make good government – and with it socio-economic development – at least possible. 

Perhaps we think we are better than all that, beyond such constitutional trifles. Yet, the fact remains that our politics today – and our society today – look much more like those of India, South Africa and Kenya than, say, like those of 1950s England. Either we find ways to dwell together in unity, or we face the kind of civil breakdown which the ancients referred to as ‘stasis’, in which all notions of the common good and the public interest are abandoned in partisan, factional, sectarian or ethnic conflict.  

Here then, we must return to matters of the spirit. A good constitution is necessary, but the best constitution cannot save us. A constitution might call us to liberty – to that political freedom which enables us, as responsible citizens, to exercise care for common things, through systems of representative and responsible ‘public government’, but that is not enough, unless we also cultivate the qualities of character to use liberty well and wisely.  

Saint Paul enjoins us not to use liberty ‘for an occasion to the flesh’ – that is, to seek our own, selfish, corrupt or partisan ends. He warns us perils of stasis: ‘But if ye bite and devour one another, take heed that ye be not consumed one of another.’  He also points to that one solution by which the degeneracy of the state, and the corruption of the constitution, might ultimately be overcome: ‘all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.’ 

In other words, if we wish to seek the common good, to be well governed, to live in peace and unity, with freedom and justice, then we have to learn to love one another. Civic and political regeneration cannot ultimately be separated from regeneration of our souls.
