The heart of the matter

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

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 myth of secular neutrality

Where academia went wrong.

In the recent horror-thriller Heretic, Hugh Grant plays Mr. Reed, a sharp-witted psychopath who imprisons two missionaries, subjecting them to ceaseless diatribes about the supposed irrationality of all religions.  Mr. Reed is also a terribly smug, self-righteous bore, a caricature of the fervent atheist who dismisses faith as mere superstition while assuming atheism is objective and neutral.  

This kind of assumption lies behind the criticisms directed by secularists at those who argue from a position of faith, as we saw recently with the debates on the Assisted Dying Bill. Yet, the notion of secular objectivity is itself a fallacy. Secularism, like any worldview, is a perspective, ironically one that is deeply indebted to Christianity, and humanity’s history of abandoning faith and its moral foundation has had disastrous consequences.  

Secularism is a bias, often grounded in an ethical vanity, whose supposedly universal principles have very Christian roots. Concepts like personal autonomy stem from a tradition that views life as sacred, based on the belief that humans are uniquely created in God's image. Appeals to compassion reflect Jesus’ teachings and Christian arguments for social justice throughout history. Claims that the Assisted Dying Bill was "progressive" rely on the Judaeo-Christian understanding of time as linear rather than cyclical. Even the separation of the secular and sacred is derived from Jesus’ teaching to “render to Caesar what is Caesar’s and to God what is God’s”. Authors like Tom Holland in Dominion and Glen Scrivener in The Air We Breathe have shown how Western societies, though often disconnected from their Christian roots, still operate within frameworks shaped by centuries of Christianity.

The antidote to human pride and self-deception was to be found in the Almighty.  Ironically, it was this humility, rooted in a very theological concern about human cognitive fallibility, that gave birth to the scientific method. 

A political secularism began to emerge after the seventeenth century European religious wars but the supposed historical conflict between science and religion, in which the former triumphs over superstition and a hostile Church, is myth. Promoted in the eighteenth century by figures like John Draper and Andrew White, this ‘conflict thesis’ persists even though it has been comprehensively debunked by works such as David Hutchings and James C. Ungureanu’s Of Popes and Unicorns and Nicholas Spencer’s Magisteria. Historians now emphasize the complex, often collaborative relationship between faith and science. 

Far from opposing intellectual inquiry, faith was its foundation. Medieval Christian Europe birthed the great universities; this was not simply because the Church had power and wealth but because knowledge of God was viewed as the basis for all understanding. University mottos reflect this view: Oxford’s "Dominus illuminatio mea" (The Lord is my light), Yale’s "Lux et Veritas" (Light and Truth), and Harvard’s original "Veritas Christo et Ecclesiae" (Truth for Christ and the Church). This intertwining of faith and academia fuelled the Enlightenment, when scientists like Boyle, Newton, and Kepler approached the study of creation (what Calvin described as ‘the theatre of God’s glory”) as an affirmation of the divine order of a God who delighted in His creatures “thinking His thoughts after Him”.   

Their Christian beliefs not only provided an impetus for rigorous exploration but also instilled in them a humility about human intellect. Unlike modernity's view of the mind as a detached, all-seeing eye, they believed man’s cognitive faculties had been diminished, both morally and intellectually, by Adam’s fall, which made perfect knowledge unattainable. Blaise Pascal captures this struggle with uncertainty in his Pensées.  

“We desire truth, and find within ourselves only uncertainty....This desire is left to us, partly to punish us, partly to make us perceive from whence we have fallen.”  

For Pascal and his believing contemporaries, the antidote to human pride and self-deception was to be found in the Almighty.  Ironically, it was this humility, rooted in a very theological concern about human cognitive fallibility, that gave birth to the scientific method, the process of systematic experimentation based on empirical evidence, and which later became central to Enlightenment thinking. 

Orwell was not alone in thinking that some ideas were so foolish that only intellectuals believed them. 

Although many of its leading lights were believers, the Enlightenment era hastened a shift away from God and towards man as the centre of understanding and ethics. Philosophers like David Hume marginalized or eliminated God altogether, paving the way for His later dismissal as a phantom of human projection (Freud) or as a tool of exploitation and oppression (Marx), while Rousseau popularised the appealing idea that rather than being inherently flawed, man was naturally good, only his environment made him do bad things.  

But it took the nihilist Nietzsche, the son of a Lutheran pastor, to predict the moral vacuum created by the death of God and its profound consequences. Ethical boundaries became unstable, allowing new ideologies to justify anything in pursuit of their utopian ends. Nietzsche’s prophesies about the rise of totalitarianism and competing ideologies that were to characterise the twentieth century were chillingly accurate. Germany universities provided the intellectual justification for Nazi atrocities against the Jews while the Marxist inspired revolutions and policies of the Soviet and Chinese Communist regimes led to appalling suffering and the deaths of between 80 and 100 million people. Devoid of divine accountability, these pseudo, human-centred religions amplified human malevolence and man’s destructive impulses.      

By the early 1990s, the Soviet Union had collapsed, leading Francis Fukuyama to opine from his ivory tower that secular liberal democracy was the natural end point in humanity's socio-political evolution and that history had ‘ended’. But his optimism was short lived. The events of 9/11 and the resurgence of a potent Islamism gave the lie that everyone wanted a western style secular liberal democracy, while back in the west a repackaged version of the old Marxist oppressor narrative began to appear on campuses, its deceitful utopian Siren song that man could be the author of his own salvation bewitching the academy. This time it came in the guise of divisive identity-based ideologies overlayed with post-modern power narratives that seemed to defy reality and confirm Chesterton’s view that when man ceased to believe in God he was capable of believing in anything.  

As universities promoted ideology over evidence and conformity over intellectual freedom, George Orwell’s critique of intellectual credulity and the dark fanaticism it often fosters, epitomized in 1984 where reality itself is manipulated through dogma, seemed more relevant than ever.  Orwell was not alone in thinking that some ideas were so foolish that only intellectuals believed them. Other commentators like Thomas Sowell are equally sceptical, critiquing the tenured academics whose lives are insulated from the suffering of those who have to live under their pet ideologies, and who prefer theories and sophistry to workable solutions. Intellect, he notes, is not the same thing as wisdom. More recently, American writer David Brooks, writing in The Atlantic, questions the point of having elite educational systems that overemphasize cognitive ability at the expense of other qualities, suggesting they tend to produce a narrow-minded ruling class who are blind to their own biases and false beliefs. 

It was intellectual over-confidence that led many institutions to abandon their faith-based origins. Harvard shortened its motto from "Veritas Christo et Ecclesiae" to plain "Veritas” and introduced a tellingly symbolic change to its shield. The original shield depicted three books: two open, symbolizing the Old and New Testaments, and one closed, representing a knowledge that required divine revelation. The modern shield shows all three books open, reflecting a human centred worldview that was done with God. 

However, secular confidence seems to be waning. Since the peak of New Atheism in the mid-2000s, there has been a growing dissatisfaction with worldviews limited to reason and materialism. Artists like Nick Cave have critiqued secularism’s inability to address concepts like forgiveness and mercy, while figures like Ayaan Hirsi Ali and Russell Brand have publicly embraced Christianity. The longing for the transcendent and a world that is ‘re-enchanted’ seems to be widespread.  

Despite the Church’s struggles, the teaching and person of Christ, the One who claimed not to point towards the truth but to be the Truth, the original Veritas the puritan founders of Harvard had in mind, remains as compelling as ever.  The story of fall, forgiveness, cosmic belonging and His transforming love is the narrative that most closely maps to our deepest human longings and lived experience, whilst simultaneously offering us the hope of redemption and - with divine help – becoming better versions of ourselves, the kind of people that secularism thinks we already are.
