Tao Te Ching
Attributed to Laozi, c. 4th century BCE — scripture.
Eighty-one short chapters, of which the fortieth compresses a complete reversion theory into one line: reversal is the movement of the Tao. What reaches an extreme generates its own turn; what hardens breaks; what yields persists. Economics rediscovered the mechanism as mean reversion, with standard errors where the poetry was. Read here as the earliest formal statement that extremes are self-correcting — the claim under every confidence band on this site.
Why the engine keeps this on the shelf
It is the prior behind every confidence band on the platform: the Loom's strands are damped back toward their documented seeds because reversion, not drift, is the assumed motion — and FIN-05 is that assumption sealed at 38%.
The record
- It is the most translated book in the world after the Bible, with more than 250 English versions alone.
- Silk manuscripts of the Laozi were excavated at Mawangdui in December 1973, dating from the early Western Han and predating the received text by centuries.
- In October 1993 a Warring States tomb at Guodian, near Jingmen in Hubei and dated to about 300 BCE, yielded roughly 800 bamboo slips, 71 of which carry the oldest known Laozi material.
- The Guodian material does not follow the received order, evidence that the eighty-one-chapter arrangement was assembled later than the sayings themselves.
Marked passages
Chapter 40, summarized: reversal is the movement of the Tao; yielding is its method. The turn is not an interruption of the way — it is the way.
Mean reversion as first principle. Every band on this platform is an estimate of how far the pendulum swings before this chapter applies.
Chapter 9, summarized: a hall filled with gold and jade cannot be guarded; wealth joined to arrogance invites its own fall; withdraw when the work is done.
Late-cycle overconfidence, diagnosed at the source. The engine reads the same signature in every euphoria stage Kindleberger catalogued.
In the author’s own words
The movement of the Tao / By contraries proceeds; / And weakness marks the course / Of Tao's mighty deeds.
Tao Te Ching, ch. 40 (James Legge, Sacred Books of the East vol. 39, 1891)
It is better to leave a vessel unfilled, than to attempt to carry it when it is full. If you keep feeling a point that has been sharpened, the point cannot long preserve its sharpness.
Tao Te Ching, ch. 9 (James Legge, 1891)

As of July 2026 every major G7 central bank was holding or tightening — the Fed at 3.50-3.75%, the ECB deposit rate at 2.25%, the Bank of England at 3.75%, the Bank of Japan at 1.00% — which is precisely the configuration from which reversals begin.
