Reference excerpt

The qīqì (Chinese: 欹器; trans. "tilting vessel" or "tipping vessel") was an ancient Chinese ceremonial utensil that automatically overturned and spilled its contents once it reached capacity, thus symbolizing moderation and caution. Both Confucian and Daoist Chinese classics include a famous anecdote about the first time Confucius saw a tilting vessel. In the Confucian tradition (e.g., Xunzi) it was also named yòuzuò zhī qì (宥座之器; "vessel on the right of one's seat"), with three positions, the vessel tilts to one side when empty, stands upright when filled halfway, and overturns when filled to the brim—illustrating the philosophical value of the golden mean. In the Daoist tradition, the tilting vessel was named yòuzhī (宥卮; "urging goblet" or "warning goblet"), with two positions, staying upright when empty and overturning when full—illustrating the metaphysical value of emptiness, and later associated with the Zhuangzian zhīyán (卮言; "goblet words") rhetorical device.

Terminology

"Phonetic loan characters", using an existing character to be read as a substitution for another of similar or identical pronunciation, have complicated interpreting several "tilting vessel" names. Prior to the Qin dynasty (221–206 BCE) when the process of standardizing Chinese characters began, scribes would use a current Chinese word and character to write another (near-)homophonous word without a standard written form, which often subsequently resulted in the creation of a new character to write the original word and meaning. For example, yāo from Old Chinese *ʔew (要; "waist" was borrowed to write yào from *ʔew-s "important; want" and the original "waist" sense was later written yāo (腰) semantically clarified with the addition of the "flesh" radical. The word qì (器; "implement, utensil, instrument; vessel, utensil used as a container or receptacle"), is a recurrent linguistic element in Chinese names and descriptions for tilting vessels. What became the most common tipping-vessel name qīqì (欹器) is a linguistic compound with yī (欹; "exclamation of admiration"), which was a phonetic loan character for qī (攲; "slanting, canted, leaning to the side; inclined; oblique; askew; unstable, unsteady"), Both these logographs are classified as radical-phonetic characters, combining the same qí (奇; "uncommon") phonetic component with two different semantic components or radicals, called the "lack" radical (欠) and "branch" radical (支). Another name with qì ("utensil"), yòuzuò zhī qì (宥坐之器; "vessel on the right of the seat" or "urging vessel"), is written as (宥坐之器) in the Xunzi and Kongzi jiayu, (宥座之器) in the Han shi waizhuan, or (右坐之器) in the Shuo yuan. The first word yòu (宥; "generous, indulgent, magnanimous; lenient, to pardon") was a phonetic loan character for yòu (侑; "urge to eat or drink"), yòu (右; "right, right side"), or yòu (囿; "circumscribed area; confine"). Bernhard Karlgren's classic Grammata Serica Recensa dictionary glosses yòu (宥) as "to be large-minded; to pardon; remit taxes; aid, encourage; mitigate" and yòu (侑) as "assist; encourage to drink; forgive". The second word is written with the related textual variants zuò (坐; "sit") and zuò (座; "seat"). The Wenzi has a final qi name, jiè zhī qì (戒之器; "warning vessel") using jiè (戒; "take precautions against, put on guard; warn(ing), monition"). Yòuzhī (宥卮; 侑卮; "a goblet for urging wine on a guest") is a "tilting vessel" name with zhī (卮/巵; "an ancient wine goblet") instead of qi (器), written with the yòu (宥; "lenient") loan character (Huainanzi) or yòu (侑; "urge to drink") clarification (Wenzi). Modern scholars such as D. C. Lau have connected this Daoist tilting goblet name with the zhīyán (卮言; "goblet words") rhetorical tactic found in the Zhuangzi.

Textual versions

Six received texts in the Chinese classics mention tilting vessels, four Confucianist (Xunzi, Kongzi Jiayu, Han shi waizhuan, and Shuo yuan) and two Daoist (Huainanzi and Wenzi). Five of these six, excluding the Wenzi, contain an anecdote about Confucius (551–479 BCE) visiting an ancestral miào (廟; "temple; shrine") and being surprised to see an ancient tilting vessel. Since multiple pre-Han and Han texts incorporated this story, it must have been "very famous" and "widely known" during the Warring States period (475–221 BCE). Since none of these early texts gives any disclaimer regarding the tilting-vessel anecdote's historicity, we may safely assume that people two-thousand years ago believed that Confucius’ temple visit had taken place as described. In brief, Confucius and his disciples visit a temple with a ritual tilting vessel, Confucius asks the caretaker about its name, says what he has heard about the vessel having three positions, which is confirmed when they pour water into it, then the disciple Zilu (in the four Confucian versions or Zigong in a Daoist version) asks a question about how to keep the tilting vessel full, to which Confucius replies with a list of four to six (depending on the text) positive attributes that should be shǒu (守; "guarded; maintained; protected") by means of its negative attribute, e.g., "Keen intelligence and sagely wisdom should be guarded by feigning stupidity". Kramers notes this story has a "great affinity" to Daoist ideas and says that in general, the Xunzi and Kongzi Jiayu are closely parallel, the Han shi waizhuan and Shuo yuan present a slightly different version, while the Huainanzi and Wenzi resemble each other in yet another version. To illustrate the types of differences in wording, all five versions begin with Kongzi guan (孔子觀; "Confucius was viewing") with three variations of the temple name. The Han shi waizhuan and Shuo yuan say Zhou dynasty (周, c. 1046–256 BCE), the Xunzi and Kongzi jiayu specify Duke Huan of Lu (魯桓公, r. 711–694 BCE), and the Huainanazi simply says the ancestral temple of Duke Huan (桓公), presumably of Confucius' home state Lu, rather than Duke Huan of Zheng (鄭桓公, r. 806–771 BCE) or Duke Huan of Qi (齊桓公, r. 685–643 BCE). Tilting-vessel accounts in the four Confucian texts are very similar, such as using the hapax legomenon shǒu miào zhě (守廟者; "temple caretaker") that is only recorded in these contexts. Note that the 1st century BCE Shuo Yuan is omitted from the following discussion because no published English translation is available.

Worked examples

Example 1 — a first encounter with Qiqi (tilting vessel)

Start with the simplest possible case. Write down what Qiqi (tilting vessel) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Qiqi (tilting vessel) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Qiqi (tilting vessel) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Qiqi (tilting vessel)

In research: Qiqi (tilting vessel) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Qiqi (tilting vessel) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Qiqi (tilting vessel) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese iconography, Chinese inventions, Chinese pottery, so understanding it makes those chapters shorter.
In everyday life: Look for Qiqi (tilting vessel) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
