Chapter 7 The Classics: Nourishing Qi, Tranquil Emptiness and the Wooden Cockerel
This chapter reads three ancient texts beside the modern research of earlier chapters. Reading them together is not mutual proof: the ancient qi is not a hormone, nor heart-rate variability; the ancient writers’ concerns overlap with today’s physiology, but their concepts belong to a different system. The original is quoted first, then the author explains where it can be compared with modern research and where the analogy stops.
Mencius: nourishing the flood-like qi
Source text
「我知言,我善养吾浩然之气。」「敢问何谓浩然之气?」曰:「难言也。其为气也,至大至刚,以直养而无害,则塞于天地之间。其为气也,配义与道;无是,馁也。是集义所生者,非义袭而取之也。行有不慊于心,则馁矣。」(孟轲及其弟子, n.d.)
“I understand words, and I am good at nourishing my flood-like qi.” “May I ask what the flood-like qi is?” “It is hard to describe. As qi it is vast and unyielding; nourished with uprightness and left unharmed, it fills the space between heaven and earth. As qi it is matched with rightness and the Way; without them, it starves. It is born of accumulated rightness, not seized by an occasional act of rightness. If one’s conduct leaves the heart dissatisfied, it starves.” (Mencius, Gongsun Chou I)
Note
Corrected on checking. The original reads 我善养吾浩然之气 (“I am good at nourishing my…”), not 吾善养吾浩然之气.
Mencius says that this qi must be “matched with rightness and the Way”; without them it “starves” (馁), that is, it weakens and loses its footing. It grows from long “accumulated rightness”, one right act after another, and cannot be obtained by a single righteous deed; any act that leaves the heart uneasy makes it starve.
Compare Chapter 3: Blascovich’s challenge and threat appraisals depend on whether people judge their resources sufficient for the demands. Mencius’s “starving” and “not starving” are also an appraisal of whether one stands on firm ground, except that he grounds it in whether one’s conduct accords with rightness, not in ability or resources. Someone who knows that, “examining himself, he is upright” (自反而缩, from the same chapter) is more likely to meet pressure in a challenge state than a threat state. This is an analogy: Mencius is discussing moral cultivation, not endocrinology, and no study has tested a link between “accumulated rightness” and challenge appraisal.
The same chapter contains an often-overlooked passage:

必有事焉而勿正,心勿忘,勿助长也。无若宋人然:宋人有闵其苗之不长而揠之者,芒芒然归,谓其人曰:「今日病矣!予助苗长矣!」其子趋而往视之,苗则槁矣。(孟轲及其弟子, n.d.)
“Work at it, but do not fix your expectations on the result; do not forget it, and do not help it grow. Do not be like the man of Song. A man of Song, worried that his seedlings were not growing, pulled at them, then went home exhausted and said to his family, ‘I am worn out today! I have been helping the seedlings grow!’ His son hurried out to look, and the seedlings had withered.” (Mencius, Gongsun Chou I)
The story of pulling up seedlings to help them grow serves as a reminder to anyone today who wants to “turn up” a hormone: growth has its own rhythm, and forcing it backfires.
The Suwen: tranquil emptiness

上古之人,其知道者,法于阴阳,和于术数,食饮有节,起居有常,不妄作劳,故能形与神俱,而尽终其天年,度百岁乃去。……夫上古圣人之教下也,皆谓之虚邪贼风,避之有时,恬惔虚无,真气从之,精神内守,病安从来。是以志闲而少欲,心安而不惧,形劳而不倦,气从以顺,各从其欲,皆得所愿。(佚名, n.d.)
“The people of high antiquity who knew the Way modelled themselves on yin and yang and kept in harmony with the arts of regulation; they ate and drank in measure, rose and rested at regular times, and did not toil recklessly; so body and spirit stayed together, and they lived out their full span, departing only after a hundred years. … When the sages of high antiquity taught those below them, they spoke of avoiding the depleting evils and thieving winds at the proper times; be tranquil and empty, and the true qi will follow; keep the spirit guarded within, and from where would illness come? So their wills were at ease and their desires few, their hearts at peace and unafraid, their bodies laboured without weariness, their qi flowed smoothly, each followed his wishes and all obtained what they hoped for.” (Huangdi Neijing Suwen, Shanggu Tianzhen Lun)
The passage has two layers. One is rhythm: “eating and drinking in measure, rising and resting at regular times, not toiling recklessly”, which connects with the circadian rhythm of Chapter 4 and the alternation of Chapter 6. The other is attitude: “tranquil and empty”, “wills at ease and desires few, hearts at peace and unafraid”. In the language of Chapter 1, few desires means not chasing an ever-rising baseline of reward; in the language of Chapter 3, “at peace and unafraid” means fewer threat appraisals.
The limits are equally clear. “From where would illness come?” is an ancient ideal, not an acceptable health claim: a calm mind does not guarantee freedom from illness, and this book does not claim that it prevents or treats any disease. “True qi” corresponds to no measurable physiological quantity.
The Zhuangzi: the wooden cockerel
Source text
纪渻子为王养斗鸡。十日而问:「鸡已乎?」曰:「未也,方虚憍而恃气。」十日又问,曰:「未也,犹应向景。」十日又问,曰:「未也,犹疾视而盛气。」十日又问,曰:「几矣。鸡虽有鸣者,已无变矣,望之似木鸡矣,其德全矣,异鸡无敢应者,反走矣。」(庄周及其后学, n.d.)
Ji Shengzi was training a fighting cock for the king. After ten days the king asked, “Is the bird ready?” “Not yet. It is still vain and swaggering, relying on its spirit.” Ten days later the king asked again. “Not yet. It still reacts to sounds and shadows.” Ten days later he asked again. “Not yet. It still glares and bristles.” Ten days later he asked again. “Nearly. Though other cocks crow, it no longer stirs. Look at it: it seems a cock made of wood. Its virtue is complete. Other cocks dare not face it; they turn and run.” (Zhuangzi, Dasheng)
The cock’s training passes through four stages: first bluster, relying on a surge of spirit; then reacting to the sounds and shadows of other birds; then glaring and bristling; and finally, when other cocks crow it is unmoved, looks like a cock carved from wood, “its virtue is complete”, and other birds turn and flee rather than fight.
Compare Chapters 3 and 5: the first three stages are states of high arousal, reacting to every stimulus; the last is not a loss of capacity but freedom from being pulled by every stimulus. In modern terms it comes close to “not mounting a threat response to every signal”. Today the idiom 呆若木鸡, “dumb as a wooden chicken”, describes someone stunned and dazed, almost the opposite of the original sense.
Note
Corrected on checking. The text says “its virtue is complete” (其德全矣); there is no phrase “a person of complete virtue” (全德之人), and the subject is a cock, not a person. Moreover, the aim of the story is still to win cockfights: it describes a quiet strength, not a withdrawal from competition.
Another passage in the same chapter bears even more directly on challenge and threat:

以瓦注者巧,以钩注者惮,以黄金注者殙。其巧一也,而有所矜,则重外也。凡外重者内拙。(庄周及其后学, n.d.)
“Shooting for a stake of tiles, one is skilful; for a stake of belt buckles, one grows fearful; for a stake of gold, one is confused. The skill is the same, but something is being prized, so the outer thing weighs heavily. Whoever gives weight to what is outside is clumsy within.” (Zhuangzi, Dasheng)
This is a description, more than two thousand years old, of high stakes making performance worse. Modern research on “choking under pressure” has a large experimental literature, and its mechanisms and conditions are still debated; this book uses the passage only as material to read beside the challenge–threat model.
Hypothesis · not established
Not established. In the same skill test (such as throwing or mental arithmetic), raising the reward from very low to very high lowers the scores of those who normally perform well, and the fall is larger in people who report higher threat appraisal (demands exceeding resources) beforehand. If, in a pre-registered within-subject experiment, the 95 % confidence interval for the correlation between the fall in performance under high reward and the threat-appraisal score lies entirely within ±0.1, the second part of the hypothesis is refuted.
Summary
All three texts move attention away from “turning something up” towards rhythm, appraisal and not being moved by outer things. This agrees with the dynamical-systems view of this book, but the texts speak of self-cultivation and nourishing life, not of physiological mechanism; their value in being read together lies in the questions they raise, not in any evidence they provide.
