The I Ching: a decision method three thousand years old

Let's be honest about the starting point: the oldest layer of the text, the Zhouyi (“the changes of Zhou”), was a divination manual. Scholars date it to the Western Zhou — the sinologist Edward Shaughnessy places its compilation in the last quarter of the 9th century BCE. You consulted it by manipulating yarrow stalks to obtain one of sixty-four figures, the hexagrams.

Tradition credits the work to founding sages — Fu Xi for the trigrams, King Wen and the Duke of Zhou for the hexagram texts, Confucius for the commentaries. Modern scholarship no longer accepts these attributions: the text says nothing of its own origin, and it formed in layers, over centuries.

In other words, the I Ching does not begin as a book of wisdom. It begins as a tool for posing a question when reason no longer suffices. What matters is what it became next.

Between the late Warring States and the early Han, scholars wrapped the old manual in ten commentaries, the “Ten Wings”. The most important, the Great Commentary, dates to around 300 BCE. These texts change everything: they read the hexagrams no longer as omens, but as figures of change, of right timing, of conduct.

This is the decisive shift. A 2nd-century-BCE manuscript unearthed at Mawangdui already shows Confucius valuing the Yi “as a source of wisdom first, and only then as an imperfect divination text”. The hierarchy is set: what counts is not prediction, but the reading of a situation.

The I Ching then becomes what it has remained: a repertoire of sixty-four human situations — waiting, conflict, retreat, breakthrough — in which anyone can recognize their own.

To consult the I Ching was not to ask “what will happen?”. It was to set down a situation, obtain a figure, and read its image as a commentary on the present moment: where the tension stands, what is rising, what asks to wait. The figure delivers no verdict; it offers an angle.

That shift is subtle but total. A good question to the I Ching isn't “will I succeed?” but “what am I not seeing in this situation?”. The first calls for a prediction — which the book doesn't give. The second calls for a way of looking — which the figure knows how to open.

Nothing supernatural is needed to understand why the exercise works. Facing a choice, the mind runs in its own grooves: it replays the same arguments and mistakes anxiety for reflection. A strong, external image — a well, an obstacle, a breakthrough — interrupts that loop. It forces you to reframe the situation in words other than your own.

It's the same principle as a journal, a devil's advocate, or a premortem: introducing a viewpoint you wouldn't have produced alone. The figure knows nothing of your life; it's you who, by testing your choice against it, surface what was weighing without being named. Often, the real question appears right there.

In that sense, the I Ching anticipated an insight that decision research has since rediscovered: you decide better by changing angle than by piling up data, and writing a choice down clarifies it more than turning it over in your head.

The twentieth century extended the wisdom reading rather than the oracle reading. Carl Jung, who prefaced Richard Wilhelm's great translation, saw in it a mirror of the present moment, not an announcement of the future (we return to this in another article). It's this lineage that Daoa claims.

Daoa stands, then, on the side of wisdom, not fortune-telling. A Yi Jing figure here opens a journal page: it announces nothing, reads no future, speaks of no destiny. It lights a present situation to help you decide — the answer and the choice staying yours.

Three thousand years later, the truest use of the I Ching may be the oldest one, stripped of the omen: to sit before a figure, look at your own choice in it, and write.
