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.

Bring on the noise: what Trump can do to help the persecuted in Iran and China

Dealing with the dictators in Iran and China needs noisy advocates.

Steve Dew-Jones

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

A fisheye view of a large debating chamber in the round.

The Human Rights Council meets in Geneva.

Pope Francis hosted a delegation from the Islamic Republic of Iran late last year for an event purportedly related to “interfaith dialogue”.

It wasn’t the first meeting of its kind, and on the face of it at least, there isn’t a lot wrong with the idea. While Iran’s relationship with most Western nations could be described as “strained” at best, the Holy See has taken a different approach, maintaining diplomatic relations with Iran for the past 70 years, including the 45 years since the establishment of the Islamic Republic.

And it has borne some fruit, helping to secure the release of a few prisoners of conscience, such as Rev Mehdi Dibaj, a Christian convert who once faced the death sentence for his “apostasy”.

But it has also opened up the Church to accusations of kowtowing to dictators and enabling regimes such as the ayatollahs’ to present themselves in a more favourable light through the high-profile photo opportunities presented by events such as the recent “dialogue” in Rome.

And it is an opportunity you can be sure the Islamic Republic was not going to pass up, with its state media unsurprisingly happy to misquote the Pope by claiming he had “stressed how Christian minorities in Iran are allowed to freely meet together and worship in churches across the country, without restriction”.

In actual fact, what the Pope really said was that “freedom of religion [is not] limited to the expression of worship; it also entails complete freedom in the matter of one’s own beliefs and religious practice”.

So, slightly different. But, no matter, you can be sure that the vast majority of the over 90,000 viewers of Press TV’s account of the event won’t have been bothered to check the accuracy of the claim, and therefore may reasonably have gone away believing that Christians truly are entirely free to worship in Iran.

Another organisation representing Christians, The World Evangelical Alliance (WEA), faced similar criticism last year when it accepted the invitation to take part in a Human Rights Council event organised by the Islamic Republic of Iran, under the deliberately misleading title, “The Role of Religions in Promoting Human Rights”.

The WEA was accused of “legitimising” Iran and even “seeming to support its propaganda as a purported defender of human rights”.

Iran will send another delegation to the Human Rights Council next week for its Universal Periodic Review (UPR), an occasion that has the potential, at least, to be quite significant, being the only UN mechanism with which the regime truly engages.

Unlike the mandates of fact-finding mission and Special Rapporteur on human rights in Iran, which Iran and its allies regularly decry as “politicised” and “selective”, the UPR is lauded even by Iran as the true and proper place for constructive criticism, as every single country undergoes the review - not only pariahs.

Several side events will be put on in conjunction with Iran’s UPR, on various themes including the situation of Iran’s Christian minority. But while the WEA last year hosted a similar event on the margins of the Human Rights Council, on this occasion it has declined the opportunity, preferring the path of “quiet diplomacy” and “dialogue” over public criticism.

Which, again, at least on the face of it, seems reasonable enough. As has been seen with the Vatican, such an approach can undoubtedly bear fruit. But it is not guaranteed.

On the other side of the debate, you have the human rights organisations who publicly call out Iran for each violation, highlighting individual cases with the hope of embarrassing Iran into change. For as much as Iran is a pariah, it still attaches some importance to its reputation on the world stage.

And again, such an approach has at times proved successful, as was seen in September with the early release from prison of two Iranian Christians who had been serving 10-year sentences due to their participation in house-churches, and whose cases had been included in a joint submission ahead of Iran's UPR.

But even this approach is not without its pitfalls. While there may be relief from accusations of kowtowing to dictators, there is also the distinct possibility that the pariah state in question may just stick its fingers in its ears and do what it wants anyway, such as in October when the Islamic Republic executed a German-Iranian political prisoner, Jamshid Sharmahd, despite years of vocal advocacy.

Advocacy certainly isn’t an exact science, at least when the experiment in question involves an unpredictable regime like the one in Tehran. Both quiet diplomacy and noisy advocacy can clearly work, but in neither case can it be guaranteed when the individual tasked with selecting their response to the advocacy is the Supreme Leader of Iran.

Surely the only way to ensure real change would be to make it too costly for the dictators to deal with their persecuted minorities in such a brutal fashion.

Western nations have a similar quandary to religious or human rights organisations. To what degree, if any, should Western governments prioritise human rights concerns over economic or political gains?

It has been suggested many times that Western nations are more concerned with oil or gas supplies, or other economic incentives, than truly seeking justice for victims of rights abuses.

When, for example, Keir Starmer speaks of wanting to have a “respectful” relationship with China, while engaging “honestly and frankly” on human rights concerns, what does that actually mean in practice?

The reality is that a behind-closed-doors discussion about a human rights infringement is unlikely to hold much sway if the violator does not share the belief that any violation has been committed, or even believes the victim to have been deserving of the treatment they received.

Whether it’s China’s targeting of the Uyghurs, or Iran’s crackdown on the Baha’is or Christian converts, one can be fairly certain that neither the Chinese nor Iranian regime feels the slightest remorse about its chosen approach.

Perhaps little could demonstrate this more than the mistreatment that continued to be handed out to Rev Mehdi Dibaj after the advocacy win of his release from prison. Just five months later, he was murdered anyway, one of three church leaders killed extrajudicially in the months after his release had been secured, including Rev Dibaj’s friend and chief advocate, Haik Hovsepian.

So is it really realistic to expect that just because we say we are concerned about the Uyghurs, the Baha’is, or the Christians, there will be any change in approach?

Surely the only way to ensure real change would be to make it too costly for the dictators to deal with their persecuted minorities in such a brutal fashion.

As ever, actions really do speak louder than words. And this is why many Iranians are hopeful that with the return of the much-maligned Donald Trump, the “maximum pressure” policy towards the Islamic Republic will also return and, through it, real change may actually be achieved.

There are many reasons, of course, to find fault with the incoming president, but when it comes to dealing with the dictators, at least, it could be argued that Trump has shown himself to have more common sense than most. The hope, as with the other approaches, is that it actually makes a tangible difference.
