The Myth of the Cold, Rational Ape

 

The Myth of the Cold, Rational Ape

Western economists have long clung to a comforting fiction: the mythical creature known as Homo Economicus. This hyper-rational, calculator-brained ghost supposedly walks through life stripping emotion from commerce, forever executing frictionless transactions to maximize immediate personal profit. It is a lovely mathematical fantasy, crafted by professors who spend too much time staring at spreadsheets and far too little time observing actual hairless primates in the wild.

If you had dropped one of those economists into the bustling markets of old Shatin, their precious models would have collapsed within five minutes. Market stalls were not operated by emotionless calculating engines, but by deeply tribal creatures navigating an intricate network of social debt and mutual survival.

Consider the village vendor selling vegetables. To a modern economist, selling produce at a discount to a familiar neighbor when a stranger is willing to pay full price is inefficient madness. To a primate trying to survive in an unpredictable world, it is pure strategic genius. The extra coins earned from a stranger vanish by sunset. But the social goodwill built with a regular buyer yields dividends for decades: a neighbor watches your stall when you step away, lends you a handcart during a harvest, and stands shoulder-to-shoulder with you when a neighboring clan comes to burn your crops.

The market was never a sterile trading floor; it was a web of kinship and tribal gatekeeping. Who secured the prime stall near the entrance? Who got away with showing up late without losing their spot? It was never dictated by the highest bidder, but by surname, lineage, and clan ties. You didn't merely buy a permit; you negotiated entry into an unspoken pact. Surplus goods were not dumped based on market clearing prices—they were absorbed collectively through informal, verbal networks of reciprocity. "I sell your leftovers today, you sell mine tomorrow."

The merchants of Shatin were indeed master accountants, but they were not calculating the immediate profit of a single transaction. They were calculating the lifetime value of human trust in a world where the state offered no safety net. Modern capitalism pretends we can replace human relationships with digital contracts, automated algorithms, and legal enforcement. But deep down, our evolutionary hardware remains unchanged: cold math builds efficient systems, but only social debts keep the tribe from tearing itself apart when winter comes.

冷酷理性猿人的荒謬神話

西方經濟學家長期以來沉迷於一個溫馨的幻想：一個被稱為「經濟人」的虛構生物。這個大腦像計算機一樣精密的幽靈，據說行走於世間時能徹底剝離情感，永遠只執行毫無摩擦的交易，以最大化眼前的個人利潤。這是一個多麼優美的數學童話，由那些坐在研究室裡盯著表格、卻極少在荒野中觀察真實靈長類動物的學者所一手打造。

如果你把其中一位經濟學家丟進昔日沙田那熙熙攘攘的墟市裡，他們寶貴的理論模型大概會在五分鐘內徹底崩潰。那裡的攤位從來不是由冷酷的計算引擎在運作，而是由一群極具部落本能的生物，在複雜的人情債與共同生存網絡中穿梭打轉。

看看那個在菜市場賣菜的老婦吧。在現代經濟學家眼中，當一個陌生人願意付全價時，她卻選擇打折賣給熟客，簡直是不可思議的效率低落。但在一個試圖在莫測世界中存活的靈長類動物看來，這是純粹的戰略天才。從陌生人身上多賺的那幾毛錢，太陽下山前就花光了；但與熟客建立的社會情誼，卻能發揮數十年的紅利：當你離開時，鄰居幫你盯著檔口；收成時，借你一把推車；而當隔壁村落帶著火種前來搶劫時，他能挺身而出與你並肩作戰。

墟市從來不是一個無菌的交易場，而是一張由血緣與部落門檻織成的網。誰能拿到入口處最好的攤位？誰能在遲到時依然留住位置？這絕非由最高出價者決定，而是取決於你的姓氏、血統與宗族關係。你買的不只是一張許可證，而是拿到了一份未竟之言的信任契約。賣不完的剩餘貨物，也不是根據市場清算價格隨手丟棄，而是透過口頭的互惠網絡共同消化：「我今天幫你賣剩菜，明天你幫我賣。」

沙田墟市裡的人確實都是精明的會計師，但他們計算的從來不是單一筆交易的即時利潤。他們計算的是，在一個沒有政府提供安全網的世界裡，一份人間信任的終身價值。現代資本主義假裝我們可以用數位合約、自動化演算法與法律強制力來取代人際關係。但在我們基因的深處，演化賦予的內在軟體從未改變：冰冷的數學可以建立高效的體制，但唯有溫熱的人情債，才能在寒冬降臨時，阻止整座部落走向自我撕裂。
