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 rave: a last bastion of hope?

Was the Brat summer the last chance for rave culture?

The Rave is a site for communal epiphany, a burst of divine revelation. Illegal raves and alternative club culture seeps into the popular imagination, informing it in ways unbeknownst to most. But it wasn’t until last Summer’s Brat (Charli XCX) landed on the global charts that people began questioning the importance of Rave and Club culture again. Is our Brat the herald of a new golden Rave dawn? I think not.

However, undergirding the Rave is something far more profound, perhaps even religious. Raving suggests that the world might be otherwise, and it does this through a temporary release from this world’s demands. What might this say about our cultural moment?

Coordinating the Rave’s aesthetic is the dance between the DJ and ravers, accentuated by the practicalities of a decent sound system, lights, and a bit of fog. Inaugurating Rave’s epiphany, though, are the diverse motions of bodies to a singular beat. Techno reduces digital sounds to their basics and then pushes that to its boundary. Circumventing the rigidity of technology’s logic are the gestures of human spontaneity on the dance floor. The rave asserts that technology doesn’t have the last say over human life.

At the Rave, those traditionally on the margins of society become the center: a temporal expression of eternal longing, momentarily experienced as a shared catharsis and liberation. The dance floor is a bulwark against an increasingly de-ritualised and dehumanising society. It is a testament to the body being a medium for hope. Whether an intoxicated body or, in a growing trend, a sober one, it is the human fleshyness which takes priority. Both options respond to how one might cope with and confront the technological barrage.

Techno began as a language for African American youth, finding a future amidst the industrial ruins of Detroit. In our late modern moment, Rave culture acclimatises the body to the persistent sound of our technological age. It subverts the dehumanising tendencies of digital culture: mass impersonal media and abstracted global conversations. Instead, a momentary online connection is used to gather offline. When you’re there, you’re not concerned about telling the world. It is an attention to the present moment.

The Rave harbours a liminal threshold between appreciation for this life and the longing for some next one.

Worryingly, some have warned that clubs will dwindle to their knees this decade, squeezed out by neighbouring property developers or no longer economically viable amidst the cost-of-living crisis. The only thing being pushed out, however, is the possible resistance to a particularly greedy homogenisation of culture. In dislocating alternative discourses of ritual, we simultaneously assert that human bodies only have one particular “rhythm”: the rhythm of ceaseless economic expansion.

The Rave resists an uncomplicated acceptance of technology’s gift. Its goods are re-scaled to an embodied celebration of life.

In Raving (2023), McKenzie Wark expands upon this, saying, ‘Techno, not as genre but as technique, lets digital machines speak. Not unlike the way jazz lets analog instruments speak… Sounds at the limit of what the machine or the instrument can do to get free. Blackness in sound as the technique of making the thing free to sound off as itself and to take the human with it, into movement, into feeling, into sensation.’ Rave’s sound quite literally brings technology’s language to the end of itself.

For some, raving is what holds them to life. For others, it’s a momentary release from it. Whilst our bodies cannot exceed techno’s interchange with technology, we do learn how to harness the potential humanness within it. The Rave harbours a liminal threshold between appreciation for this life and the longing for some next one. In twisting its technological medium into a more human configuration, rave culture participates in hope.

Back in 1965, theologian Jürgen Moltmann wrote, ‘Hope’s statements of promise, however, must stand in contradiction to the reality which can at present be experienced. They do not result from experiences, but are the condition for the possibility of new experience… They do not seek to bear the train of reality, but to carry the torch before it. In so doing they give reality a historic character.’ While Moltmann is writing concerning Christianity and the crucified Christ, his framework for thinking about hope is helpful. Hope never occurs outside of history. The Rave embraces this historical moment and attempts to inhabit it as a contradiction.

Recently, I went to Rhythm Section International’s tenth-anniversary party at EartH, Hackney. Rhythm Section was founded as a music collective and is still curated by Peckham’s own Bradley Zero (BZ). Known globally, its parties and label imprint span techno, house, jazz, funk, spoken word, and RnB.

I first danced to BZ’s DJing at a record shop in 2018 while still living in Melbourne. The beauty of this particular community is that it provides a bridge for what Wark identifies: just as jazz brings analogue instruments to their limits, techno does the same for digital. As experienced recently at EartH in Hackney, Rhythm Section tries to push digital and analogue sounds to their threshold across the night. In contrast to the pure techno rave, BZ’s selection causes a polyphonic liberation. Joy is found through the instruments slapped just as much as in the DJ faders pushed.

This joy was evident in the diversity of ages and cultures present. “Mature heads” danced alongside students; some swayed, while others vogued. Without spaces such as these, where else can we celebrate the diversity of human responses to the same sound?

My concern with club culture’s demise is that those places of contradiction are swallowed up by a faux vision of “smoothness”. We replace spaces of alternative being with sameness. A diversity of aesthetics is converted into another apartment complex. We make room for the novelty of Brat but not the culture she draws upon.

Rave culture attempts to redefine the dominant technological language of our day, making the body its lens and not the periphery. By privileging the human body, Rave’s hope acknowledges profound discontent with the world but understands that all “escape” is temporary. This re-calibration enacted in Rave’s ritual de-escalates the supposed importance of technology’s ceaseless expansion. Thus, it exposes a more profound longing, one where it will be an eternal dance that deepens the love of life by going ever deeper into the particularities of individual bodies and their movements.

Because it offers a form of explicit hope, the Rave is a ritualised space filled with the belief that there can be “something more”. And this more-ness is, ultimately, encountered in the face of those we dance with; whether in a fleeting glance to ask, “Are you alright?” or the mutual smile that says, “I love this song”.
