We don’t truly know what the spirituality of human beings looked like before Christianity. But what we do know is that,
long before the Bible or the Quran,
humans maintained a deeply intimate bond with the world around them. This bond was woven in the silence of forests, beneath the stars that returned each evening, in the mystery of the sun rising tirelessly above the horizon to flood the earth with light, a light seen as divine, life-giving, sacred. Then, as darkness slowly returned, the silent dance of the stars resumed its course, reminding everyone of the sacred regularity of the universe. These early forms of worship were likely centered around natural cycles, light, darkness, fertility, the seasons, all intimately tied to the concrete lives of our ancestors: the hunter, the gatherer, the fisherman, or the farmer. These forms of nature-rooted spirituality may date back 70,000 —or even 100,000—years before our era. 2
Gradually, other dimensions of life came to be venerated. The oldest known place of worship to this day, dating back to around 10,000 BCE and located in present-day Turkey 1, bears witness to ritual practices centered on powerful animals: snakes, wild boars, vultures. These may have been part of totemic cults, in which animals were celebrated for the forces they embodied.
Later came the worship of ancestors and spirits, followed by what we now call polytheism: first in primitive forms in Mesopotamia and ancient Egypt, before becoming more structured in the Greek world. Eventually, over time, monotheism established itself as the dominant form, up to the present day.
If we return to the time when Stoicism was born, in the 4th century BCE, as civilizations expanded, cities became more structured, and knowledge accumulated, humanity’s view of the divine began to change.
The gods were no longer just masters of natural forces or protectors of a community; they became figures of a broader, more abstract order. In the Greek world, this shift gave rise to a more philosophical form of religiosity, one in which people no longer simply worshipped, but sought to understand. Among these currents of thought, one in particular stood out for its vision of the world and the divine: Stoicism. There, in our school founded beneath the colonnades of Athens, a radical idea took shape: that the cosmos is not merely the work of the gods, but is itself God. That nature, reason, and the divine are one and the same. This is where what would later be called pantheism begins—another way of believing, thinking, and living: not outside the world, but at its very heart.
At this point in the article, if I had to give you a simple definition, I’d say that pantheism is the doctrine that God and the world are one and the same, or, in other words, that the totality of being is divine.
The Stoics thus revived this divine being, omniscient, eternal, and present in all things, along with a more ancient spiritual order, in which nature was no longer a mere backdrop, but the beating heart of all things, the very place where the divine revealed itself.
They quickly came to recognize, in the cycles of nature, that everything alive grows, reaches its full flourishing, and then—like every other living thing around it—declines, withers, and eventually fades away.
They saw in the cycle of the seasons a metaphor for life. They observed the sea, endlessly retreating and returning, like the breath of a living being. The grain of wheat falling into the earth, dying in order to be reborn as a stalk, an ear, a new life. The trunk of a tree, solid and majestic, bearing within it the silent rings of each lived year, before hollowing out, splitting open, and slowly returning to the soil from which it once sprang. The stag, proud and strong at the height of its power, roaming the forest, until its strength wanes, its antlers fall, and its body at last joins the ground it once walked.
Everywhere, they recognized a rhythm, a necessity, an invisible logic at work.
But what they saw, what stood out amid the multitude of the world’s complexities as a silent certainty, was this vital force, this impulse toward life, the breath that animates everything that grows, struggles, and endures. They saw it in the sap rising, in the animal getting back up, in the child learning to walk.
This drive toward existence,
toward flourishing,
appeared to them as a primary virtue, a fundamental energy worthy of reverence, because it revealed the world’s intelligence, its movement, its coherence. This was, no doubt, for them, one of the earliest forms of the sacred: life itself, in its forward thrust, venerated as an expression of the divine.
From this intuition was born a particular way of thinking about the world, what would later be called pantheism. Unlike religions that separate God from the world, pantheism holds that the divine is immanent in all things. There is not, on the one hand, an external creator, and on the other, a creation. There is only the Whole, animated from within by a force, a reason, a unity.
The fundamental principles of pantheism rest on this idea: that the world and the divine are one and the same; that nature, in its entirety, is a manifestation of God. Every being, every stone, every gust of wind is infused with this presence. It is not merely a matter of saying that God is in the world, but that the world is God, a God who is not personal, not anthropomorphic, but universal, rational, and alive.
It is no longer a form of worship directed at a distant god, but an inner reverence for the order of the world itself. And this is precisely what the Stoics expressed with a previously unseen philosophical rigor: by identifying the Logos, this cosmic reason, with the divine, they transformed pantheism from a mere religious intuition into a doctrine. A way of thinking, and of living, in harmony with the universe as a whole.
In this pantheism, the Stoics found a deep echo of what they believed in: the idea that the divine is not separate from the world, but—
Immanent and present in all things
The divine is not external to the world, it is present in everything, in the movement of the stars just as in human reasoning. It does not reside “elsewhere,” but expresses itself in the very order of reality.
…with a unity of being
There are not two worlds, a heavenly world and an earthly one—but a single, coherent Whole in which all things are interconnected. Animals, stones, rivers, stars, and the moon all partake in the same cosmic substance, in the same great Whole.
…in which nature is sacred
Nature is neither neutral nor profane: it is divine, because it is the direct manifestation of the Logos, the universal reason that animates it. The universe is like a living being, endowed with an inner intelligence.
…and the rational cosmos
The world is not governed by chaos or chance, but by an internal logic, a necessary and ordered structure. For the Stoics, this logic is called the Logos: a rational fire that permeates everything.
…fostering an ethics of harmony
Since human beings are part of this great Whole, their task is to live in accordance with nature, accepting the order of the world, cultivating virtue, self-mastery, and inner peace.
Thus emerges a way of inhabiting the world without fleeing from it, of recognizing in every thing, in every moment, the discreet but constant presence of a greater order, a cosmic wisdom with which the Stoic chooses to align.
