What does it mean to be human, and why does the thought of ceasing to exist disturb us so profoundly? Across every civilization, every religion, and every age, one desire has remained strikingly constant: the wish to live beyond the natural span of a human life. The quest for immortality is not a modern obsession fueled by biotechnology startups or science fiction – it is one of the oldest expressions of the human condition. Long before laboratories and gene-editing tools, human beings looked to the gods, to myths, and to the heavens for a way to escape death. Understanding why this desire exists, and how it has evolved, is central to understanding humanity itself.

A longing as old as civilization
Immortality, in its broadest philosophical and religious sense, refers to the indefinite continuation of the mental, spiritual, or physical existence of individual human beings. Earlier anthropologists like Sir Edward Burnett Tylor and Sir James George Frazer assembled convincing evidence that the belief in a future life was widespread even in regions of primitive culture. What is remarkable is not that isolated communities held this belief, but that virtually all of them did – independently, across continents and centuries. This universality points to something deep and structural in human consciousness: we are, perhaps uniquely among living creatures, aware of our own mortality. And that awareness seems almost inevitably to generate a longing to escape it.
Philosophically, immortality implies the continuation of personal identity – not just being remembered, but the persistence of a self that can say “I exist.” This distinction matters. A sports legend like Babe Ruth may be fondly remembered long after death, but unless someone can genuinely claim to be Babe Ruth, he is not immortal in the philosophical sense. True immortality, as thinkers have long debated it, requires the survival of the person – not merely their reputation.
The earliest story ever written is about this fear
The oldest known work of literary fiction in human history is not a love story, not an account of war – it is a story about the terror of dying. The Epic of Gilgamesh, whose earliest versions date to around 2100 BCE during the Ur III Period, chronicles the adventures of the semi-divine king of Uruk in ancient Mesopotamia. At its heart, the epic is a meditation on mortality.
Gilgamesh is described as two-thirds divine and one-third mortal – powerful, proud, and seemingly invincible. But when his closest companion, Enkidu, dies, Gilgamesh confronts his own finitude for the first time. Standing over his friend’s lifeless body, Gilgamesh understands that he, too, is mortal. The invincible hero breaks, abandons his throne, and embarks on a desperate quest to uncover the secret of eternal life. His journey leads him to the sage Utnapishtim – the only mortal ever granted immortality by the gods – who delivers a brutal lesson: such a gift is not for human beings.
The narrative reflects the universal human fear of mortality and the desire for transcendence. When Utnapishtim challenges Gilgamesh to stay awake for a week to prove his worthiness of immortality, Gilgamesh’s eventual failure underscores the inherent limitations of mortals. Returning to Uruk empty-handed, Gilgamesh gazes at the great walls of his city and begins to understand that what endures is not the man, but what the man builds. Through the written word, Gilgamesh does in fact conquer death – winning his immortality each time his tale is read. The epic’s deeper message is not that immortality is impossible, but that legacy is its closest human substitute.
How different cultures framed the quest
The Mesopotamian narrative was far from unique. Despite the immense variety of beliefs on immortality across cultures, they may generally be reduced to three basic models: the survival of the astral body, the immortality of an immaterial soul, and physical resurrection – and most religious traditions have combined elements of all three.
In ancient Egypt, elaborate burial practices including mummification reflected the belief that preserving the physical body was necessary to secure a place in the afterlife. From at least the time of the ancient Mesopotamians, there has been a conviction that gods may be physically immortal, and that this is also a state the gods sometimes offer humans. Greek mythology, meanwhile, engaged the topic with characteristic complexity. The tale of Tithonus – granted immortality but not eternal youth, condemned to wither endlessly – illustrated that the desire for unending life carried its own dangers if poorly conceived.
Immortality was one of the chief problems of Plato’s thought. Maintaining that reality is fundamentally spiritual, he tried to prove immortality by arguing that nothing could destroy the soul. Aristotle, by contrast, conceived of reason as eternal but resisted defending personal immortality, since he believed the soul could not exist without a body. The Epicureans took yet another angle – arguing that death simply means the end of consciousness, and is therefore nothing to fear. The Stoics believed that it is the rational universe as a whole that persists, while individual humans merely have their allotted periods in the drama of existence.
In the Indian tradition, the Hindu Katha Upanishad raises the question directly: “This doubt there is about a man departed – some say: He is; some: He does not exist.” The Upanishads, which form the basis of most traditional Indian philosophy, are centrally preoccupied with the nature of humanity and its ultimate destiny. Across the Islamic tradition, thinkers like Avicenna declared the soul immortal, while Averroës, staying closer to Aristotle, accepted only the eternity of universal reason.
The psychological roots of the immortality impulse
Why is this desire so persistent? One influential framework comes from philosopher and psychologist Ernest Becker, whose 1973 work The Denial of Death argued that much of human culture and behavior is driven by the anxiety of knowing we will die. Immortality projects – endeavors aimed at achieving some form of lasting impact or enduring legacy – provide a sense of purpose and meaning, allowing people to believe their actions have an impact that extends beyond their lifetimes. This explains why humans build monuments, raise children, write books, found institutions, and pursue fame. These are all, in a sense, strategies for defeating death.
Philosopher Luc Ferry noted that by having children, humans assure their continuity, becoming part of an eternal cycle of nature – a universe of things that can never die. Spanish philosopher Miguel de Unamuno framed the same drive even more urgently: he argued that when reason cannot express the cardinal human hunger for self-perpetuation and the longing not to die but to live forever, one turns to irrationalism – to faith, to art, to love – anything that promises a form of continuation.
In his book Immortality, philosopher Stephen Cave argues that this desire has taken on four distinct forms over human history: staying alive through magic or science; seeking resurrection; finding solace in the concept of an immortal soul; and pursuing immortality through work or artistic creation. Each form is a different answer to the same unanswerable question.
From myths to molecules: science enters the picture
The shift from mythological to scientific framings of immortality is one of the most significant intellectual transitions in modern history. The pursuit of physical immortality before modern science included alchemists who sought the Philosopher’s Stone, and various cultural legends such as the Fountain of Youth or the Peaches of Immortality, inspiring attempts at discovering an elixir of life. These were not considered fringe pursuits – they were taken seriously by educated people in their time.
What differs today is the means: no longer symbolic or mythical, but grounded in advances in genetics, neuroscience, and artificial intelligence. At the dawn of the 20th century, average global life expectancy was scarcely above 30 years. A century later, it has more than doubled, largely thanks to advances in sanitation, vaccines, antibiotics, and modern medicine. What was once miraculous is now routine. The question for researchers today is whether this trajectory can be extended indefinitely – whether aging itself can be treated as a disease to be cured.
According to transhumanist scholar Nick Bostrom, transcendentalist impulses have been expressed at least as far back as the quest for immortality in the Epic of Gilgamesh, as well as in historical quests for the Fountain of Youth, the Elixir of Life, and other efforts to stave off aging and death. Some transhumanists advocate a biological approach to counter-aging with the aim of halting or even reversing the aging process, while others believe the essence of existence lies in the brain, whose memories and functioning should be preserved through cryogenics or mind-uploading processes.
Private companies, including those heavily funded by individuals like Larry Ellison, Peter Thiel, Sergey Brin, and Jeff Bezos, are now committed to slowing, halting, and even reversing aging. The ambition has moved from the monastery to the laboratory, from prayer to genomics. Yet the underlying impulse – the refusal to accept that human consciousness simply ends – remains exactly what it was in ancient Uruk.
The philosophical tension at the heart of the quest
Not all philosophers celebrate the desire for immortality. Some argue, pointedly, that without death there is no meaningful life. Philosopher Samuel Scheffler, in his book Death and Afterlife, tries to defend the claim that an immortal life would be no life at all – arguing that temporal scarcity is a condition of value in human life, and that without the threat of death, it would be difficult to make sense of our existence.
Philosopher Shelly Kagan argues that immortality presents an inescapable dilemma: either our characters remain essentially the same, meaning we would eventually exhaust all interests over an infinite stretch of time; or our characters are radically changed, making us so different from our current selves that we would have little reason to care about that future being. Either way, the argument goes, immortality fails to deliver what we actually want from it.
Based on Immanuel Kant’s account of the parameters of human understanding, an ageless existence is arguably unintelligible to human beings – this incomprehensibility denies us cognitive access to the object of comparison with our mortal existence, on the basis of which agelessness might be endorsed with rational confidence as better. In other words, we may not actually know what we are wishing for when we wish to live forever.
What the longing itself tells us
Perhaps the most philosophically interesting thing about the desire for immortality is not whether it can be satisfied, but what it reveals about human nature. That this longing has appeared, independently, in nearly every culture and every era suggests it is not a cultural accident. It is woven into the structure of self-conscious existence. To be aware of oneself as a person, persisting through time, accumulating memories and relationships and meanings – and then to know that all of this will simply stop – is a strange and difficult thing to fully accept.
Among humanity’s most enduring motivations is the desire for permanency: to survive, to leave a legacy, and to transcend the limits of time. From ancient myths of immortality to today’s laboratories, this impulse has been a constant in human history. Whether satisfied through religious faith, philosophical consolation, artistic creation, biological children, or scientific research, the underlying drive remains the same. It is, at its core, a refusal to treat human experience as disposable.
What changed over the millennia is not the desire but the grammar in which it is expressed. The Sumerian king sought a magical plant at the bottom of the sea. The medieval alchemist sought the Philosopher’s Stone. The twenty-first-century biotech investor funds research into telomere extension and senescent cell removal. The vocabulary shifts; the sentence stays the same.
What do you think? If the finite nature of life is what gives our choices meaning and urgency, does the pursuit of radical life extension risk emptying human experience of its depth – or does a longer life simply offer more time to find meaning? And when we examine humanity’s long obsession with immortality, are we looking at a fundamental truth about consciousness itself, or at a sophisticated refusal to come to terms with the natural order?
