Earth, water, fire, air, wood, metal, void, aether, sulphur, mercury, salt — every major civilization built a small set of primitives to explain matter, change, energy and life. They were proto-scientific frameworks, not primitive superstition. 地、水、火、气、木、金、空、以太、硫、汞、盐——每一个伟大文明都构建了一组少量的基本元素以解释物质、变化、能量与生命。它们是原始科学的雏形，而非"原始迷信"。
This platform compares ten elemental systems side by side — their internal logics, their applications to medicine, governance, military strategy and architecture, and what each one reveals about the cognitive style of the civilization that built it. 本站将十大元素体系并列比较——它们的内在逻辑、它们在医学、政治、兵法、建筑中的应用，以及每一种体系所揭示的、构建它的文明的认知风格。
Each card is one civilization's answer to the same question: what is reality made of, and how does it change? The colours are their canonical hues, the elements their basic primitives, the logic line their internal operating system.每一张卡片是某一文明对同一问题的回答：现实由什么构成、又如何变化？颜色是其经典色相，元素是其基本原语，逻辑行是其内部操作系统。
Wu Xing is most often translated as "five elements", but every classical Chinese commentator would correct you. The five are not substances: they are stages of an ongoing transformation. Wood is the phase of expansion, fire of peak activity, earth of centring, metal of contraction, water of return. The system encodes change first, matter second."五行"常被译为"五元素"，但古代中文注疏皆会更正你：五行并非物质，而是不断转化中的五个阶段。木是伸展之相、火是极动之相、土是居中之相、金是收敛之相、水是归元之相。该体系先编码变化，再附及物质。
Wood burns into fire; fire's ash builds earth; earth solidifies into metal; cool metal condenses water; water nourishes wood. Each phase produces the next — a closed productive cycle that has no beginning and no end.
木燃为火、火灰成土、土凝为金、金冷生水、水润养木。每一相生下一相——一个无始无终的封闭生产循环。
Wood roots split earth; earth dams water; water extinguishes fire; fire melts metal; metal cuts wood. Five conquests in a pentagram — the system's negative-feedback loop, applied in ancient medicine to diagnose excess and in war to choose the right ground.
木根破土、土壅塞水、水灭火、火熔金、金断木。五克成五芒——这是该系统的负反馈回路，古医以此诊过盛，用兵以此择利地。
Liver↔wood, heart↔fire, spleen↔earth, lung↔metal, kidney↔water. The body recapitulates the cosmos. A pulse felt at the wrist tells the practitioner which phase is ascendant. Acupuncture rebalances the cycle.
肝木、心火、脾土、肺金、肾水。身体重演宇宙。腕脉告诉医者哪一相在盛。针灸重整其循环。
A site's water flow, vegetation (wood), exposure (fire), soil (earth) and rock (metal) are read together. The dwelling is sited so the five phases generate one another rather than overcome each other. An elemental ecology, centuries before the word existed.
堪舆师审一处地之水脉、植被（木）、向阳（火）、土质、岩骨（金），五者并察。择居使五行相生而非相克。这是一种早在词出之前数百年的元素生态学。
Sun Bin and the Mawangdui silk texts assign each terrain to a phase: marsh = water, plain = earth, forest = wood, mountain = metal. A general who attacks a "metal" army from a "fire" position has the cycle in his favour. Logistics dressed in cosmology.
孙膑与马王堆帛书将各类地形配属五行：泽水、原土、林木、山金。以火位攻金军，五行加持。后勤披上宇宙论的外衣。
The pre-Socratics each picked one principle: Thales said water, Anaximenes air, Heraclitus fire, Xenophanes earth. Empedocles (~450 BCE) was the synthesiser who made it four. Aristotle then paired them by qualities and added a fifth — aether — for the perfect heavens.前苏格拉底诸贤各举一本原：泰勒斯举水、阿那克西米尼举气、赫拉克利特举火、色诺芬尼举土。约公元前 450 年，恩培多克勒为之综合，定为四。亚里士多德再以性质成对，并为完美的天界增第五——以太。
Heaviest, falls to centre. Body, bone, stability. In Aristotle's universe, this is where the ground is — and where heavy objects belong by nature.
最重，下沉至中心。身、骨、稳定。在亚里士多德的宇宙中，土在此处——且重物自然归属于此。
Heavy but flowing. Blood, phlegm, lymph. Below air, above earth. The great equaliser — water levels itself.
沉而流。血、痰、淋巴。在气下、在土上。伟大的均平者——水自取其平。
Light, rises. Breath, soul (psychē was originally a wind-word), atmosphere. The realm of birds, weather, life-giving exhalation.
轻，上升。呼吸、灵魂（psychē 原本即风之字）、气候。鸟、天、施生之嘘息所属之域。
Lightest, rises highest. Light, heat, life-warmth. The phase Heraclitus took to be fundamental: panta rhei, all flows.
最轻，升至最高。光、热、生气。赫拉克利特视之为本原的相：panta rhei，万物流变。
Godai borrows from the Indian Pañcabhūta but stacks the elements as a sequence of decreasing density: solid → liquid → energy → motion → emptiness. The fifth, kū (void), is not a substance — it is the open ground in which the others arise. Refracted through Shingon and Tendai esoteric Buddhism into stūpa architecture and into the structure of Musashi's Book of Five Rings.五大借自印度五大种，但将元素依密度递减堆叠：固→液→能→动→空。第五，空（kū），并非物质——而是其余诸大得以涌现的开放底基。经真言、天台之密宗折射，化入塔形建筑与宫本武藏《五輪書》之结构。
Solid, stable, resistant. In Musashi's chapter, the Ground is the foundation: study, posture, basic stance. You cannot fight without it.
固、稳、抗。武藏《五輪書·地之卷》：地是基础——研学、站姿、基本架。无地则无以战。
Takes the shape of its container. The water chapter is technique — a flexible body that responds to the opponent rather than fixing on a plan.
随器而形。水之卷为技——柔身应敌，而非固守一谋。
Energy, decision, kill. The fire chapter is engagement — initiative, breaking the enemy's rhythm, the moment of conversion.
能、决、杀。火之卷为接战——主动、破其节奏、转化之刻。
Movement that has no body. The wind chapter is comparative study of other schools — knowing how others fight by feeling their movement, like wind detecting obstacles.
无身之动。風之卷比较他流——以风觉障之法，体察他人之战。
The Vedic and later Sāṃkhya systems pair each element with a sense and a sense-quality (tanmātra): earth with smell, water with taste, fire with sight, air with touch, ether with sound. Cosmogony recapitulates perception. The system underwrites Ayurveda, yoga, and most of the body-work traditions of South Asia.吠陀及后来的数论将每一元素与一感官、一感性（唯量 tanmātra）配对：地与嗅、水与味、火与视、风与触、空与声。宇宙生成重演感知。该体系是阿育吠陀、瑜伽以及南亚多数身体修炼传统的底层。
Heaviest, structures the body's frame. Bones, teeth, nails. Smell is the sense that grounds you in your environment.
最重，构成身体之架。骨、齿、爪。嗅觉将你植于环境。
Liquidity, fluids, plasma. The element that lets parts hold together. Taste, the chemical sense, is its perceptual counterpart.
液、体液、血浆。让各部得以相聚。味觉，作为化学感官，是其感知对应。
Digestive fire (agni), metabolic heat, intellectual brilliance. Sight is light is fire — the only sense that operates at distance through energy.
消化之火（agni）、代谢之热、智之光辉。视即光即火——唯一以能量远距运作之感官。
Breath, prāṇa, nervous activity. The element of communication — between organs, between thoughts. Touch detects motion against the skin.
息、prāṇa、神经活动。通讯之元——器官之间、念头之间。触觉感知触肤之动。
Iranian cosmology stands apart: each element is sacred, and impurity is moral as much as physical. The cosmos is a battlefield between the truth (Asha) of Ahura Mazdā and the lie (Druj) of Angra Mainyu. Fire is the visible aspect of the wise lord — every fire-temple keeps a single eternal flame.伊朗宇宙论独树一帜：每一元素皆神圣，污秽既是物理的也是道德的。宇宙是阿胡拉·马兹达的真理（Asha）与安格拉·曼纽的谎言（Druj）之间的战场。圣火是智主的可见面相——每一座火庙皆守一支永燃之火。
Fire is not a symbol of Ahura Mazdā — it is his presence. Polluting fire (e.g. by burning impure substances) is a serious offence. Three grades of sacred fire are kept at three grades of temple.
火非智主之象征——而是其临在。污火（如焚不洁之物）为大罪。三等圣火供奉于三等庙宇。
Rivers and springs are sacred. To bathe an unwashed body in flowing water is a sin. The hydraulic ethic of Iran — qanats, abundant baths — has Zoroastrian roots.
江河泉眼皆神圣。以未净之身浴于流水为罪。伊朗的水利伦理——坎儿井、丰盛之浴——根源于祆教。
A corpse is the supreme pollutant; burying it would defile the earth. The Towers of Silence (dakhma) instead expose the body to vultures, dissolving it without contaminating any element.
尸首为至污；土葬即玷地。寂没之塔（dakhma）反置尸体于秃鹫之啄，得以分解而不染任一元素。
Wind has a dual nature in the Avesta — there is a benevolent and a malevolent wind. Air is what lets the soul travel after death across the Chinvat bridge.
风在《阿维斯塔》中具二相——善风与恶风。气使死后之魂得以越钦瓦特桥而行。
Alchemy was always a double project: a chemistry, and a soteriology. The matter on the bench and the alchemist at the bench are mirrored — purify the one and you purify the other. The same ambition recurs in three civilizations, with three different chemistries.炼金术始终是双重事业：一门化学，与一门救赎论。台上的物质与台前的炼金者互为镜像——纯化其一，即纯化其二。同一志愿在三大文明中重现，化学路径各异。
Four medical traditions, each grounded in its civilization's elemental system, treating the body as a recapitulation of the universe. Each maps illness onto imbalance — but the units of imbalance differ.四大医学传统，各以其文明之元素体系为基，将身体视为宇宙的重演。各以失衡定疾——但失衡之单位不同。
| Tradition传统 | Unit of analysis分析单位 | Disease as疾即 | Treatment治疗 |
|---|
A cosmology is not a private opinion — it is the cognitive frame of an entire civilization. Each frame makes some moves easy and others almost unthinkable. Five axes recur whenever you compare them.宇宙论非私见——而是整个文明的认知框架。各框架使某些动作易行，使另一些近乎不可思议。比较时反复出现的轴有五。
| Axis轴 | Pole AA 端 | Pole BB 端 |
|---|
Most of the elemental specifics were wrong. The pattern-recognition instincts that produced them were right. Six places where the ancient frame and the modern instrument shake hands.绝大多数元素细节是错的。但产出它们的模式识别直觉是对的。六处古框架与现代仪器握手相会的地方。
Move the dials to assemble a cosmological profile. The verdict at the bottom matches your configuration to a known historical archetype: Wu Xing, Greek-Aristotelian, Mahāyāna / Vedanta, Zoroastrian dualism, modern apocalyptic, or a high-disequilibrium fringe state.移动旋钮以拼装宇宙论画像。底部判决会将您的配置匹配至一个已知的历史原型：五行型、希腊—亚里士多德型、大乘 / 吠檀多型、祆教二元、现代末世，或边缘失衡态。
