The Axial Age

Something happened between roughly the eighth and the third centuries BCE that, when you first see it laid out on a map and a timeline together, looks almost impossible. In that narrow window, in several places across Eurasia that had little or no contact with one another, humanity produced, all at once, the greatest concentration of world-shaping thinkers it has ever managed. In India, the Buddha sat down under a tree and would not get up until he understood suffering. In China, Confucius walked the roads teaching how a good person and a good society hold together, while somewhere a contemporary we call Laozi set down the elusive wisdom of the Way. In Persia, the prophet Zarathustra split the cosmos into a war of light and dark. In the small kingdoms of Israel, the Hebrew prophets thundered that their God cared less for sacrifice than for justice. And in Greece, a line of restless men, Thales, Pythagoras, Socrates, Plato, Aristotle, invented the very habit of asking what the world is made of and how we can know, and answered without appealing to a single god. A German philosopher, Karl Jaspers, gave this astonishing simultaneity a name. He called it the Axial Age, the age on which human history turns.

What turned? The whole center of gravity of the human spirit. Recall the world of the last Part: god-kings, temple economies, blood sacrifice, a cosmos run by quarrelsome deities who mainly wanted feeding. The Axial Age is the moment humanity, in place after place, lifts its eyes from appeasing the gods and begins instead to ask how to live. It turns inward, toward conscience and the soul, and upward, toward something transcendent that stands above even the gods and the king. It discovers the individual as a moral agent, answerable not merely to the crowd or the crown but to truth. And it produces, again and again, from mouths that never spoke to each other, the same startling ethical core.

Stand close to each of these awakenings and the family resemblance is uncanny. In the forests of India, the composers of the Upanishads turned away from the old fire-sacrifices to ask what lies behind the self, and arrived at a breathtaking answer: that the innermost essence of a single person, which they called Atman, and the ultimate ground of the entire cosmos, which they called Brahman, are one and the same thing. The Buddha, a little later, set even the eternal self aside and taught with almost clinical precision that suffering arises from craving, and that craving can be released, laying out a practical eightfold path to do it. In China, Confucius located the sacred not in the heavens but in the space between people, in what he called ren, the deep humaneness that ought to bind parent to child and ruler to ruled, while the Daoists pointed almost the opposite way, toward wu wei, an effortless flowing with the grain of the Way rather than against it. In Israel, prophets like Amos and Isaiah did something no temple priesthood had dared, telling their own people in the name of their own God that their sacrifices were worthless if they ground the face of the poor, that what the divine actually wanted was justice and mercy. These are genuinely different medicines, and we should not pretend they all say the same thing. But notice that they are all prescriptions for the same newly diagnosed ailment: the restless, self-aware inner life of a person who has begun to ask whether the way they are living is the way they ought to live.

That convergence is the part worth pausing on, because it is genuine and it matters for a question we will carry to the end of this book. Confucius, asked for a single word to live by, offered reciprocity: do not do to others what you would not want done to you. Half a world away and unaware of him, the rabbis would later call almost the identical rule the whole of the law. The Buddha and the Stoics of Greece, with no possible contact, arrived at strikingly similar diagnoses, that much of our suffering comes from craving and from our judgments about things rather than the things themselves, and at similar cures, in the disciplining of attention and desire. Compassion, the danger of the ungoverned ego, the hollowness of ritual without righteousness, the worth of the examined inner life: these show up independently, in traditions that agree about almost nothing else. It is possible to read that as coincidence. It is more honest, and more interesting, to notice that when many separate human communities think hard and long about how conscious social creatures can live well together, they tend to discover some of the same answers, as if the structure of a flourishing life were a real thing out there to be found, the way the physics of light was real and kept producing eyes. We will return to that possibility when we ask, near the end, whether meaning is invented or discovered.

The Greeks, meanwhile, were doing something with a different flavor and enormous consequences: they were inventing reason as a public tool. When Thales proposed that the world could be explained by water and natural process rather than by the whims of Poseidon, he did a small thing that changed everything, he offered an account that others could challenge, test, and improve. Pythagoras heard the cosmos as number and harmony. Democritus guessed, with no instrument but his mind, that all things are made of tiny indivisible particles he called atoms, and he was, in the deepest sense, right, twenty-four centuries before we could prove it. Socrates made a career of showing the confident that they did not know what they thought they knew, and died for it. This willingness to follow an argument wherever it leads, to prize the question over the comfortable answer, is the seed of the science and the philosophy that will eventually produce this very book, and, much later, its author.

Why it all happened at once, we do not fully know, and we will not pretend to. The likeliest story is that the Iron Age had spread cheaper tools and writing more widely; that new economies of coin and trade and crowded cities were dissolving the old certainties and throwing people of different beliefs together; that the collapse of the Bronze World had discredited the old god-kings and cleared a space for new answers. All of this probably fed it. But the cause is less remarkable than the result: across a single handful of centuries, humanity thought its way to the ethical and philosophical foundations that still, today, run most of the lives on Earth. If you hold a religion or a moral code, it almost certainly took recognizable shape in this window.

These new systems, though, did not arise from nothing. They were built on top of a far older and stranger layer, a bedrock of myth and symbol and archetype that every one of these cultures inherited from the deep past and that binds them together beneath their surface disagreements in ways they themselves did not suspect. To understand the Age of Meaning fully, and to meet the deepest and most disputed pattern in this whole book, we have to stop the clock for one chapter and go down into that older layer. We have to talk about the gods and the monsters. Above all, we have to talk about the snake.
