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.

Politics

Virtues

Are virtues irrelevant in today’s uncertain politics?

We need to exercise the character traits that uphold our values.

Emerson Csorba

Emerson writes on geopolitics. He is also a business executive and holds a doctorate in theology.

MSNBC.

In Oliver O'Donovan's Finding and Seeking, the theologian makes a telling comment about virtue, virtue referring to ‘the goodness the world has already seen and known…. Talk about virtue is always third person talk, observers’ talk about deeds that have already taken determinate form.’

Put differently, virtue is about the past. It is about how others have lived and acted in admirable ways. But it is not about today, in all of its ambiguity and uncertainty.

To put it directly – virtue falls apart when hit with reality. It is easy to talk about what virtuous people have done, much harder to be virtuous in the present. Or so O’Donovan says.

There has been a lot of talk over recent years about the need for virtues and values in politics (and in the world more widely), but what even are these things?

Values are principles or standards that individuals or societies consider important.

Virtues are moral excellences or traits of character, such as courage, patience, or humility.

Virtues are the moral character traits individuals need to uphold values, in practice.

When thinking about virtues and values, I often reflect on a simple but profound point made by Nigel Biggar speaking at Oxford University many years ago:

"If you want pure heroes, you won't have any."

Put differently, people – including the most virtuous at first glance – are complicated.

Yet, our world is one in which virtue seems to be in short supply. Some would even say virtue (and values) are non-existent, or on the verge of extinction.

The older I become, the more I am left reflecting on why it is that so few individuals – in political life, but also more generally – seem to live without principle. Integrity – which I define as ‘your word (or principle), and action aligning’ – seems increasingly a thing of the past.

Many seem to think that integrity is ‘old-fashioned,’ acting accordingly, saying one thing and doing another as if there are no repercussions.

This is replaced with an ‘anything goes’ mentality, focused on short-term gratification. It is a “you do you” culture, acting without conscience. People seem to believe there are few if any repercussions for doing bad things. This culture is not only permitted, but even celebrated.

The American situation is, of course, the example par excellence of this. American politicians and diplomats wake up each morning waiting for what their President will write on social media, responding accordingly. Alliances are thrown out the window. Nothing is off the table.

There is seemingly less interest in Western societies in being good persons, doing what is right in hard circumstances, and where few or no people are watching.

Whether in politics or in society more widely, people seem increasingly focused on protecting themselves, doing whatever they need to do to get ahead, rather than looking out for each other.

So where do we draw the line? Is there space for virtue (and values) in a world where growth is slowing, and more people are battling for parts of a shrinking pie?

I believe the answer is yes. My sense is that many people are today yearning for clarity of values and virtues in a world that is becoming much more anchorless.

There does then seem to be interest in values and virtues, but it is perhaps worth remembering that values and virtues are like muscles... It is possible to lose these muscles without practice.

In my home of Canada, where I recently moved back, many value decency, politeness, and a sense of moderation.

In 1955, while serving as Canada’s Secretary of State for External Affairs, Lester B Pearson put his figure on this pulse, delivering a series of lectures at Princeton University entitled Democracy in the World. Pearson argued that a sense of moderation is a leading value for Canadians.

He described this as a ‘confidence in the ability of the peoples and the leaders of democratic nations to grow into the new situations and to accept the greater self-discipline which the preservation of freedom in an interdependent world requires.’

And he saw Canada as especially emblematic of this ability to grow into new situations, this adaptability in working in an interdependent world.

Many Canadians believe that the thirteen provinces and territories need to adapt and work together in order to respond to the threat of the United States.

The candidate for Leader of the Liberal Party, Mark Carney, seems to agree (and is rising in the polls because of this), whereas his opponent Pierre Poilievre is moving in the opposite direction given his more combative approach. But Poilievre has time and the opportunity to turn this around, channeling Canadians' frustrations into a vision focused on the values and virtues we share in common.

In other words, Canadians value working together when faced with challenges, valuing this solidarity when times are tough. We become more courageous the tougher things become.

The virtue of courage is here a noteworthy virtue, so well proven in the Great War battles of Vimy Ridge, Passchendaele and The Somme, or the Battle of the Atlantic in World War Two.

We see this Canadian virtue emerge often in times of crisis.

Andrew Davison in previous writing in Seen & Unseen is especially eloquent on courage, writing that this virtue is:

‘both bracing and realistic. It reminds us that all is not well with the world. We will often need courage because doing the right thing can be costly.’

There does then seem to be interest in values and virtues, but it is perhaps worth remembering that values and virtues are like muscles – a point made by Carney in previous writing and speeches. And Poilievre, well-known for his considerable discipline, certainly understands the importance of the exertion that builds muscle."

It is possible to lose these muscles without practice. Over recent years, societies and individuals have become more permissive, rather than encouraging consistent exercise.

The question therefore is less about whether values or virtues will survive in the harsh light of reality. Instead, it is whether societies – their political representatives and citizens – are open to making the short-term investments necessary to uphold what they believe is good in their countries and in the world?

A tall task, to be sure, but one that I believe is both possible and necessary for Canadians and non-Canadians alike. Canada can here be an example for the world.

This task – upholding certain values and virtues, is not third person talk, as O’Donovan suggests. It is rather an imperative for action in the present. We are called to act accordingly today.
