Seven writers, one weather. The snow is first seen, then only heard, then parted in, shared with strangers, weighed south against north, chosen by a single flake, and at last walked through, from a Tang river to the far north of a fairy tale.
- 江雪 · Liu Zongyuan
- 夜雪 · Bai Juyi
- 白雪歌送武判官歸京 · Cen Shen
Seven ways of writing to someone not yet born, each aimed further off than the last: from words that outlast a family’s titles to a cover that must teach its finder how to play the record inside.
- 穆叔論不朽 · Zuo Qiuming (traditionally attributed)
- A Possession for All Time · Thucydides
- That It May Long Endure: From the Edicts of Asoka · Asoka
Six readers on what reading is for, beginning with a father’s warning on a winter night and ending with the cheapest way to travel. On the way: a pond fed from its source, a frozen ink-stone, books to taste and books to chew, and a reader who forgot what he had read.
- 冬夜讀書示子聿 · Lu You
- 觀書有感 · Zhu Xi
- 送東陽馬生序 · Song Lian
Eight looks at the same moon: shared by two people far apart, mistaken for frost, invited to drink, questioned, missed at Mid-Autumn, guessed to be circling the earth, joined by the moons of Jupiter, and at last stood on.
- 望月懷遠 · Zhang Jiuling
- 靜夜思 · Li Bai
- 月下獨酌·其一 · Li Bai
Eight lamps, from a friendship measured in lamplight to Faraday’s candle on a lecture table. If someone asked me what this library is about, this is the trail I would hand them.
- 寄黃幾復 · Huang Tingjian
- 贈衛八處士 · Du Fu
- 夜雨寄北 · Li Shangyin
Seven texts by and about makers: a cook, a recorder of trades, papermakers, a commoner who made type, a young inventor and his fifty models, a mountain carved by water, and a poet who praised all trades. Read them for the details that only someone who did the work would notice.
- 莊子·養生主 · Zhuangzi (Zhuang Zhou)
- 天工開物·自序 · Song Yingxing
- 天工開物·殺青(節選) · Song Yingxing
Seven texts on the oldest arrangement in learning, one person handing what they know to another: a bell that rings as hard as it is struck, a student sent home twice to think, a teacher who will not answer, a lecture on a piece of chalk, and a poet’s rule for learning from everyone.
- 禮記·學記 · Anonymous Confucian scholars
- 荀子·勸學 · Xunzi (Xun Kuang)
- 師說 · Han Yu
Seven writers stand on a riverbank and think about time, from Confucius and Heraclitus, who lived in the same years at opposite ends of the world, to Whitman on the East River speaking to passengers a hundred years later. By the end the river is carrying readers as well as water.
- 論語(學而、爲政、里仁、述而、子罕) · Confucius and his disciples
- The Fragments of Heraclitus · Heraclitus
- 長歌行 · Anonymous
Seven steps from a reed in a pond to a program for the Bernoulli numbers. Each is a way of making numbers do more work for less effort, and by the end the methods are something a machine could carry out.
- 九章算術·句股(節選) · Anonymous (Han dynasty compilers)
- Elements, Book I: First Principles, Propositions 1 and 47 · Euclid
- 孫子算經(選) · Master Sun (identity unknown)
Technical writing is supposed to be for machines; these six pieces were written to people. Read them for the reader each one has in mind: whoever holds the counting rods, the next programmer, a colleague up all night, a friend remembered, a stranger who opens the source file years from now.
