My brother-in-law Ong Geok Soo working in Singapore wrote to me and to everybody through WhatsApp telling us he does not believe in a soul. He mentioned when a person or any living creature dies, the body just break down without any soul left. He says he uses his "theory on quantum mechanics" to explain but he did not say how his "quantum mechanic" works - how life could exist without a soul?
Let me explain my strongest beliefs in spiritual entities far beyond science can explain.
Human knowledge has always advanced within the narrow window of what can be observed, measured, and verified. Yet beyond this visible world lies a deeper question that science, by its very nature, cannot fully answer: whether human existence is purely material, or whether there exists a non-physical essence, what many traditions call the soul.
Modern science, including disciplines such as Quantum Mechanics, has greatly expanded our understanding of the physical universe. However, its strength is also its limitation. Science is designed to study matter, energy, space, and time. It does not possess the instruments or methodology to investigate what lies beyond the physical. Therefore, to conclude that the soul does not exist based on scientific reasoning is not truly a scientific conclusion, but rather a philosophical stance rooted in materialism.
Interestingly, even within physics, reality is far less solid and straightforward than it appears. What we perceive as tangible matter is, at its deepest level, governed by invisible fields, probabilities, and interactions that cannot be directly seen. This alone reminds us that unseen realities can exist and exert influence without being directly measurable. It is therefore not unreasonable to consider that existence may include dimensions beyond our current ability to detect.
The biblical narrative presents a profound and consistent view of human nature, describing man not merely as a physical organism but as a being composed of body, soul, and spirit. In Genesis, life begins when God breathes into man, and he becomes a living soul. In the teachings of Christ, the soul is portrayed as something beyond the reach of physical harm, and in the writings of the apostles, a clear distinction is made between the physical body and the inner, enduring essence of a person. This perspective suggests that what we see is only one aspect of human existence, while the deeper reality lies within.
Beyond the individual soul, Scripture also speaks of an unseen order, a structured hierarchy of invisible forces and entities. These are described not as abstract ideas, but as active realities influencing the course of the world. The struggle of human life is portrayed as extending beyond physical conflicts into a realm of unseen powers, authorities, and spiritual forces. Such descriptions imply that reality is layered, with dimensions that remain hidden from ordinary perception yet are no less real.
The Bible further emphasizes that the visible universe itself originates from the unseen. What is perceptible to our senses is temporary and passing, while the unseen is enduring and eternal. There are even moments recorded where this hidden
dimension becomes briefly visible, suggesting that it exists alongside our physical world, though normally beyond our awareness.
What is remarkable is that this understanding is not confined to Christianity alone. Across civilizations and centuries, thinkers and traditions have converged on similar ideas. Plato reasoned that the soul is immortal and distinct from the body, while René Descartes proposed a dualism between mind and matter. Immanuel Kant acknowledged that certain realities, including the soul, lie beyond empirical proof yet remain deeply significant to human reason. In Islamic thought, the soul is described as belonging to a domain known fully only to God. In Hindu philosophy, the Ātman represents the eternal self that transcends physical existence. These parallels suggest that the intuition of a non-material essence is deeply embedded in human consciousness.
At the same time, human life in the physical sense is undeniably brief. Even under the best circumstances, it spans only a few decades, a fleeting moment in the vast timeline of the universe. Scripture vividly captures this reality, describing life as a vapour that appears for a short while and then disappears. Everything tied to the physical body, strength, beauty, wealth, and achievement, inevitably fades with time.
It is within this context that one of the most penetrating questions in Scripture is posed: what value is there in gaining the whole world if one loses the soul? The teachings recorded in Mark 8:36 and Matthew 16:26 confront us with a profound contrast between the temporary and the eternal. Material success, power, and recognition may appear significant, yet they are ultimately transient. If the soul endures beyond physical life, then sacrificing it for temporary gain would represent the greatest possible loss.
Disease and death is no respecter of any person. I know of many of my doctor colleagues and friends have passed away, and so were all my professors and senior lecturers in England who taught me. I have written at least two article on the brevity of human life here:

2. Also on humanity fleeting moments

This does not mean that physical health and well-being are unimportant. Caring for the body is both wise and necessary. However, when viewed in the broader perspective of existence, it becomes clear that the body is temporary, while the question of the soul, if it indeed exists, carries far greater and lasting significance.
When my brother-in-law Engineer Ong Geok Soo appeals to “quantum theory” to deny the soul, he is, perhaps unknowingly, stepping beyond the boundaries of science into philosophy. Physics can describe how particles behave, but it cannot determine whether consciousness is purely material or whether a deeper, non-physical reality exists. The absence of evidence within scientific instruments does not constitute evidence of absence in metaphysical questions.
In the end, the question of the soul is not merely scientific, it is existential. It asks each of us to consider what we are, what endures, and what ultimately matters. If there is even a possibility that the soul is real and eternal, then it would be wise to give it the attention it deserves. For if the unseen is indeed eternal, and the seen is only temporary, then the priorities of life must be reconsidered in that light.
Let me give a summary version for my brother-in-law and to all gentle readers here:
Human beings have long debated whether we are purely physical or possess a non-material soul. Science, including Quantum Mechanics, studies only the physical world and cannot prove or disprove the existence of the soul. Therefore, denying the soul based on science is a philosophical belief rather than a scientific fact.
The Bible teaches that humans consist of body, soul, and spirit, and that the soul endures beyond physical death. It also describes unseen forces and dimensions that exist beyond human perception, suggesting that reality is far greater than what we can observe.
This idea is supported by many thinkers such as Plato, René Descartes, and Immanuel Kant, as well as by other religions, all of which recognize a non-material aspect of human existence.
Human life on earth is brief, rarely exceeding 100 years, while the soul is eternal. This is why Scripture asks: what is the value of gaining the whole world if one loses the soul (Mark 8:36; Matthew 16:26)? Material success is temporary, but the soul carries eternal significance.
I think while we should care for our physical health, it is far more important to consider the state of our soul. For if the unseen is eternal and the visible is temporary, then the greatest investment we can make is not in what we possess temporary in this world we are on transit for a 100 years at maximum, but in what we ultimately gained eternally in another world. While we are still here, I don't think it is very pleasant to describe ourselves or any person as a soulless person like a piece of stone. Everyone likes to be labelled as a living, loving, soulful person with compassion and empathy - that's the living soul in us.
We need to respect God who created us who gave us life, and not be arrogant especially if we are professionals like scientists, doctors, and engineers.
I thought I had written many times on this subject. Here's just one of them; my brother-in-law and others can read and delve further.

Let me once again share my thoughts on the existence of a soul using this analogy or illustration on a article I wrote earlier on:
The Dual Symphony of Existence (Part 1) :
https://scientificlogic.
I shall continue to explain logically on this subject why I think our soul is the "eternal negative photographic film" of our positive, but temporary photo print here in this world, and from this negative copy (soul) many positive copies of our lives can be duplicated in another worlds when we die.
Give me time to think how to put it before I can write. If readers can freely share their thoughts with me, it would be a blessing for their souls too for it is more blessed to give than to just receive.
(Acts 20:35)
