君子食无求饱,居无求安。——孔子
(jūn zǐ shí wú qiú bǎo, jū wú qiú ān — Kǒngzǐ)

Translation: “Nobles seek neither satiety in food nor comfort in dwelling.”
Explanation:
Confucius’ ascetic minimalism principle “君子食无求饱(jūn zǐ shí wú qiú bǎo), 居无求安(jū wú qiú ān)” (Nobles seek neither satiety in food nor comfort in dwelling) establishes humanity’s earliest philosophy of intentional scarcity. The character 求(qiú)—depicting 衣(yī, clothing) + 又(yòu, repetitive grasping)—metaphorizes disciplined restraint as artisans carefully selecting furs: enough for survival, never excess. This shaped 汉代察廉制(hàn dài chá lián zhì) (Han Austerity Audit System), where officials’ meal portions and home sizes were regulated—those exceeding 求(qiú) limits faced public rice sack-carrying punishments to restore humility.
Tang Dynasty 节用令(jié yòng lìng) (Frugality Decrees) operationalized this through 三足法(sān zú fǎ) (Three-Legged Rule): bureaucrats’ residences could only contain furniture supporting three activities—sleeping, eating, working. Modern tech mirrors this: Xiaomi’s “90% product” strategy enforces 求(qiú)-driven minimalism—phones remove 10% non-essential features annually, while founder Lei Jun’s office contains just a desk, chair, and prototype wall.
Neuroscience validates ascetic benefits. 2023 fMRI studies show 求(qiú)-style restraint activates the prefrontal-insula circuit (delayed gratification), increasing willpower reserves by 23%. AI systems now simulate this—Alibaba’s FrugalBrain recommends product designs with 8-10% material reductions while maintaining functionality.
From Tesla’s “Gigafactory floor sleeping pods” enforcing 居无求安(jū wú qiú ān) to CRISPR labs using 食无求饱(shí wú qiú bǎo) nutrient-restriction protocols to boost researcher focus, this 2,500-year-old principle becomes innovation’s paradoxical catalyst. As quantum computing demands 求(qiú)-level error austerity, Confucius’ clothing-and-grasp character becomes our symbol for essentialist progress.
