道 Dao Knowledge Base

Taiqing Asks the Infinite

The Zhuangzi's second-ranking system for the question 'do you know the dao?': the Infinite says no, the Non-Doing says yes and even lists its numbers, and the Beginningless hands down the verdict — not-knowing is deep, knowing is shallow. The chapter's sharpest line is the questioner's own sigh: not-knowing, that is knowing! knowing, that is not-knowing! And the follow-up completes the sentence: the dao cannot be heard, seen, or spoken.

PRIMARY SOURCESCHOLARLY INTERPRETATION

The story

Taiqing asked the Infinite: do you know the dao? The Infinite said: I do not know. He then asked the Non-Doing, and the Non-Doing said: I know the dao. — And do you know it with a number? — Yes. — What is the number? — I know the dao can be noble, can be base, can be gathered, can be dispersed. This is the number by which I know the dao. (吾知道之可以貴，可以賤，可以約，可以散，此吾所以知道之數也).

So Taiqing took the Non-Doing’s answer to the Beginningless and asked for the verdict: between the Infinite’s not-knowing and the Non-Doing’s knowing, which is right and which is wrong? The Beginningless’s ruling is the chapter’s second-ranking system stated in four plain words: not-knowing is deep, knowing is shallow; not-knowing is inside, knowing is outside (不知，深矣；知之，淺矣。弗知，內矣；知之，外矣). Then Taiqing raises his head — the received text says 中而叹, sighed in the middle; Lu Deming’s textual note records that the Cui edition reads 卬, raised his head — and delivers the chapter’s sharpest line, which is also its best-known proverb:

弗知乃知乎！知乃不知乎！孰知不知之知？ — Not-knowing, that is knowing! Knowing, that is not-knowing! Who knows the knowing of not-knowing?

The Beginningless is not finished. Three negations follow, each in the same form: the dao cannot be heard — what is heard is not it; the dao cannot be seen — what is seen is not it; the dao cannot be spoken — what is spoken is not it. And the turn that ties the knot: do you understand that what forms the formed is itself unformed? The dao does not fit a name (知形形之不形乎，道不當名). The last paragraph escalates from the object to the question itself: one who answers a question about the dao does not know the dao. Even one who asks has not yet heard the dao. The dao has no question, and a question has no answer. To ask what cannot be asked is to ask into emptiness; to answer what cannot be answered is to have nothing within (道无問，問无應。无問問之，是問窮也；无應應之，是无內也). And the closing sentence draws the map of the failure: whoever does this does not see the cosmos from outside and does not know the great beginning from inside — that is why he never gets past Mount Kunlun, never roams the great void (不過乎崐崘，不遊乎大虛).

Why it is told here

Because this is the chapter’s second ranking of knowledge, set one step deeper than the first. The chapter opened with Zhi asking Wuweiwei — three questions about knowing the dao, answered by silence, by a forgotten answer, and by the Yellow Emperor’s eloquent reply, with the verdict that the silent one was truly right and the eloquent one farthest away. That first story ranked speech against silence. This one ranks claims against each other, and the winner is not even silence but a denial: the Infinite’s flat 吾不知 — I do not know. The word 无穷 (infinite) is itself the plot: the dao’s own name for itself is the one who says he does not know it.

The two rankings, side by side. The chapter opened with a story where speaking too well was the error (the Yellow Emperor); it closes this one where speaking at all is the error. Between them sits the whole epistemology: silence beats speech, denial beats list, and the sigh of a confused student beats both.
