A Cosmic Purpose

“If there is any optimism for mankind, any chance of unifying our species, then it remains in the possibility that our existence is, in fact, bound with a greater purpose.” (The sentient mind)


What is the purpose of life? As sentient beings, we ask this question in our search for meaning and happiness. As living beings, the answer is simple. The purpose of life has always been, and will always be, survival. If nature has any aim, then it is to perpetuate its existence. And if we have any aim, then it is to perpetuate ours—we exist to exist, and we live to continue life. There is no greater meaning to our being and no higher purpose for us to realize. Because any reason for existing must, at the very least, involve an existence—there can be no purpose in being without being itself.

“Since we cannot prove the absence of purpose, it would be wise for us to assume a purpose that agrees with both our logic and our intuition.” Quite beautifully, the only logical purpose in existence—to exist—also happens to satisfy our most visceral instinct—our desire to exist. If our nature reflects the nature of reality, then our struggle for existence is a fundamental part of existing. We want to be because we are meant to be. After all, our religious intuitions claim that we are meant to be forever.

“The mind wants to be, so it considers itself an eternal being. We want to continue beyond the spacetime boundaries of the Universe. While some might call this fanciful imagination, most of the world considers this their fate. The mind is inevitably drawn to the idea that its being is just one part of a never-ending sequence.” And there is only one logic that can satisfy our longing for eternal relevance. In our search for purpose, I believe that our species will come to one conclusion: we were created to create.

In several billion years, an expanding Sun will vaporize all the water on Earth.

Because the truth is, everything dies. You and everyone you know will die. In three billion years, life on Earth will die. In 8 billion years, the Sun will die. Our galaxy will die, and so might the Universe. But still, the mind considers itself eternal—a likely delusion, but a powerful indication that a reality beyond space and time has long been fully conceived by the human mind. And while the religious mind looks at eternity and discovers its own relevance, the scientific mind looks at eternity and sees its own insignificance. But no matter your view, there is, in the religious perspective, a truth that we all must face: the only alternative to extinction is eternity. And because of our intellect, the unthinkable has become thinkable; science has presented mankind with the possibility of an indefinite existence. If we want to survive, then eternal life can no longer remain a religious fantasy; it must now become our cosmic vision. Because we, the created, have become the Creator. We are God becoming self-aware.

“I do not make any clear distinction between mind and God. God is what mind becomes when it has passed beyond the scale of our comprehension.” – Freeman Dyson

“[Reason tells me of the] extreme difficulty or rather impossibility of conceiving this immense and wonderful universe, including man with his capability of looking far backwards and far into futurity, as the result of blind chance or necessity. When thus reflecting I feel compelled to look to a First Cause having an intelligent mind in some degree analogous to that of man.” – Charles Darwin


Perhaps best known for its discovery of the Higgs boson, the Large Hadron Collider (LHC) in Switzerland has been critical in advancing our knowledge of quantum physics.

“I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.” – Galileo Galilei


“At our current rate of technological growth, humanity is on a path to be godlike in its capabilities.” – Elon Musk

There is no foreseeable end to the progression of the human mind and the evolution of its intelligence. The growth of our knowledge is accelerating. We predict cosmic and quantum phenomena with increasing precision, and manipulate the laws of nature in ways that are inconceivable to the ordinary mind. We expect to find and spread life beyond Earth within a few centuries. We will soon have the ability to edit our own genes, and to guide our own evolution. And we will soon create machines more powerful—minds more intelligent—than ourselves. We dream of colonizing the galaxy, and of discovering the truth about our origins. As Sagan said, “we are a way for the Cosmos to know itself.”


Everything may die, but death does not come without a hope for birth. As the child becomes the parent, so the created becomes the Creator. Maybe we are, after all, made in the image of God.

We are a way for the Cosmos to know itself, and we may certainly be a way for the Cosmos to continue itself. Our ability to reason, to feel, and to self-reflect—maybe it’s not some aimless accident. Rather, our existence evolved to know and to value itself for the sole purpose of continuing itself. Awareness arose from life and for the extension of life, in this universe or the next. It could be as simple as colonizing Mars, as complex as creating a big bang, or as grand as expanding the cosmic web.


The Laniakea supercluster, our filament of the cosmic web, was defined by mapping the movements of 8,000 galaxies after subtracting the effects of cosmic expansion.


The Milky Way sits near the divide between the Laniakea and Perseus-Pisces Superclusters. These structures surround a vast region of empty space known as the Local Void.


“In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider. They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends powerfully on how well we understand this Cosmos in which we float like a mote of dust in the morning sky.” – Carl Sagan


For the sake of humanity, “we must consider the possibility that we exist for a reason. Because intellectuals and imbeciles alike are bound to this principle of human nature: cooperation requires a unifying objective. Scientists and sociopaths, like everyone else, will not work together without a reason to.” And there is only one reason that makes any sense: the purpose of life is to continue life. And if mankind is relevant, then our purpose is cosmic. But with a capacity for creation comes an equal capacity for destruction. Should we continue to exist as intelligent and sentient beings, then we have a moral responsibility to understand and to cherish our existence.

“We on Earth have just awakened to the great oceans of space and time from which we have emerged. We are the legacy of 15 billion years of cosmic evolution. Now we have a choice: we can enhance life and come to know the universe that made us, or we can squander our 15 billion-year heritage in meaningless self-destruction.” – Carl Sagan

“It is, surely, our responsibility to do everything within our power to create a planet that provides a home not just for us, but for all life on Earth.” – Sir David Attenborough

“Our loyalties are to the species and to the planet. Our obligation to survive and flourish is owed not just to ourselves but also to that Cosmos, ancient and vast, from which we spring.” – Carl Sagan

“We exist to exist, and we live to continue life.” There is no motive as moral and no purpose as noble as this. Because the truth is, life is not a right—no one is entitled to existence. Rather, life is a privilege that comes with an obligation. We are part of something beautiful, and our job is to continue its beauty. It’s time that we, as a species, find our place in the Universe. Maybe there is a reason why man, confined to this pale blue dot, is so drawn to his destiny in the cosmos. As Sagan said, “the sky calls to us. If we do not destroy ourselves, we will one day venture to the stars.”

An intellectual note: A concept of eternity is, I think, a pivotal step in the evolution of consciousness. The very fact that we can comprehend a reality beyond space and time, be it an afterlife or a multiverse, or that we have the intellect to deduce and ponder the low-entropy state from which our universe arose, speaks to the possibility that the mind itself is somehow implicated in the continuation of its reality. Perhaps higher consciousness is responsible for reproducing the order from which we have evolved. Perhaps our spiritual obsession with eternity is not some misguided delusion, but the fullest manifestation of nature’s struggle for existence. This is an idea that every intelligent being must consider, because the assumption of such truths may be necessary for the survival and evolution of a species beyond the stage at which humanity presently finds itself.

“The significance of our lives and our fragile planet is then determined only by our own wisdom and courage. We are the custodians of life’s meaning. We long for a Parent to care for us, to forgive us our errors, to save us from our childish mistakes. But knowledge is preferable to ignorance. Better by far to embrace the hard truth than a reassuring fable. If we crave some cosmic purpose, then let us find ourselves a worthy goal.” – Carl Sagan

A religious note: As a child, I would spend hours studying a single chapter of the Bible. Every verse had many layers of meaning that was to be extracted by prayer, meditation and careful examination. The goal was to know God, to connect with my Creator through truths powerful enough to change the world. And like religion, my message is one of purpose and hope. Like faith, my philosophy is about finding God—but not through a book or a prayer. Rather, I discovered the nature of my Creator through the nature of his creation. In searching the mind of man, I found the mind of God. If we crave eternal relevance, if we want a cosmic purpose, then this we must assume: we are God becoming self-aware.
