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.

Experiencing Tbilisi's cold shoulder

Georgia’s warm welcome doesn't extend to refugees fleeing Iran.

Steve Dew-Jones

Steve is news director of Article 18, a human rights organisation documenting Christian persecution in Iran.

On the surface, Georgia has a lot going for it: natural beauty, historic sites, lovely food and wine.

It also boasts an extremely free market. Anyone can to set up a business of their choosing within a couple of hours, should they have the wherewithal.

But therein also lies the rub. Life is not so easy for those without such wherewithal - perhaps they don’t have sufficient capital, or vision; a disability prevents them; or they try but fail.

And then life is not so easy in Tbilisi.

My focus on my recent trip to Georgia, as an employee of an Iranian Christian charity, was its small Iranian population - and principally those who have claimed asylum there.

I spoke to several such individuals during my stay, and the conclusion that I reached was that Georgia is a lovely place to live, provided that you: a) have money; and b) are happy not to speak out about sensitive issues.

Which, honestly, sounds eerily like the country from which my Iranian friends fled in the first place.

When he ignored the warnings, the threats escalated. His car was broken into, and someone even came to his church, claiming to have a bomb strapped to himself.

Take Reza, for example, who left Iran eight years ago and came to Georgia in the hope that in a country where nearly 90 per cent are Orthodox Christians, he would be free to practise his chosen faith.

He even set up a church there, and for a while all was good. Until he started getting involved in protests against the regime back in Tehran.

Reza joined demonstrations outside the Iranian embassy in Tbilisi - which is in a lovely area of town, right next to the Russian embassy and also, somewhat awkwardly, that of Ukraine.

He also protested outside the “Ferdowsi Educational Complex” - a Shia school with a sign outside proclaiming it as an entity of the Iranian embassy.

And for these protests, Reza received some, at first, gentle reprimands. He was called by a private number, encouraging him not to take such action again in the future.

When he ignored the warnings, the threats escalated. His car was broken into, and someone even came to his church, claiming to have a bomb strapped to himself.

It was only at this point that Reza decided, against his initial intentions, to claim asylum.

But though the Georgian immigration service eventually acknowledged him to be a Christian - unlike many of his fellow Iranian asylum-seekers - they did not accept that this fact would put him at risk of persecution were he to return home.

To which the only rational response is a wide-open mouth and outstretched arms.

Have the Georgian immigration service not read the news? Do they not know that Christians - and more specifically, evangelical Christians and converts like Reza - face sustained and systematic persecution?

The answer to this question, I was to discover, is two-pronged.

Firstly, there is Georgia’s close relationship with the Islamic Republic, the reason for which, sadly and all too predictably, is of course money.

“Georgia is a small country,” a lawyer who deals with immigration cases like Reza’s told me.

“It’s surrounded by three big countries: Russia, Turkey and Iran, and can’t afford to have bad relations with all of them.”

Both Russia and Turkey have history of seeking to occupy Georgia, while Russia has made no secret of its hope of re-establishing the territories it once held, including, one presumes, Georgia.

In this context, it is little wonder that little Georgia does not feel able to cast aside so lightly its relationship with its third mega-neighbour, Iran.

And when an Iranian claims asylum in Georgia - on whatever grounds - what message would it send for the Georgian government to recognise that claim?

In the case of Christians like Reza, the message would clearly be that Iran persecutes Christians, which is an uncomfortable reality for a close ally of Iran to publicly admit.

You can search his name on Google, in both English and Persian, and it’s safe to say that what you would find would not please the Islamic Republic.

The second prong at play, meanwhile, which is equally uncomfortable to speak about, is the reality that in general Georgia’s Orthodox Christians tend to share some of Iran’s ill-feeling towards evangelicals.

“They think of us the same way as Jehovah’s Witnesses,” Reza explained.

“A Georgian friend of mine accused me three times of being a spy for America,” another convert told me.

Another, whose case was rejected because Georgia’s immigration service did not accept he was a Christian, told me the questions he was asked in his interview related only to elements of the Orthodox faith, about which he had no idea.

And when this individual sought to explain his own reasoning for his deeply held faith - for which he was arrested in Iran - they told him he could only answer the questions posed.

And so he said that he could not. And so they rejected his claim, declaring that it had not been established that he was a Christian.

An easy win.

I could focus now on the particular challenges faced by asylum-seekers who are unfit to work - two of whom I met, and who receive no support from the state - but I would like to close with one final example which I think highlights the absurdity of the situation.

And that is the example of Behzad Asiaie, an Iranian whose claim for asylum was based on his political activity and not his faith, although he has since converted to Christianity - for which he blames Reza, as, no doubt, would the Iranian and dare I say even Georgian government.

The striking thing about Behzad’s case is that it’s extremely well documented. You can search his name on Google, in both English and Persian, and it’s safe to say that what you would find would not please the Islamic Republic.

For one thing, Behzad has already spent a year in Tehran’s Evin Prison for his activism. Added to that, since arriving in Georgia five years ago, with no intention to claim asylum, he started a new activist group called Hamrasho (which means “all together”), which has organised protests about various things outside the edifices of the Islamic Republic in Tbilisi.

As part of the protests, which is where Behzad met Reza, Behzad even filmed himself burning images of Iran’s Supreme Leader, and published it on social media.

So, when the Georgian government rejected his eventual asylum case and told him that they didn’t think he would have any problem were he to return to Iran, the jaw really must drop open.

My conclusion upon leaving Georgia was that it really is a lovely country - provided that you have money and don’t make too much noise.

I put this perspective to a Russian couple, who I met on my last night in town, and they - like Reza and Behzad before them - nodded in agreement.

For they, like my Iranian friends, are exiles, having fled Russia because they are against Putin’s war.

They told me they know of no other Russians among the thousands in Tbilisi who support Putin’s war, but nor do they know any who would be foolish enough to protest about it - whether back home, or outside the Russian embassy in the lovely Vake district of Tbilisi.

I penned this article on my last night in Georgia in a Ukrainian restaurant housed roughly between the two edifices of the Islamic Republic of Iran, which felt about right.

The entire restaurant is painted in the colours of the Ukrainian flag; the Wifi name is “Slava Ukraine”; and the password, I was told, translates as “super slava”.

Which seems to be about the loudest protest that one can get away with in Tbilisi.
