Chapter IThe Philosophy

A good theme is almost nothing. It is a room with the right light in it, a chair that you forget you are sitting in. It clears the table so that thinking has somewhere to happen.

Nous is built for the long read — the essay begun in the morning, the footnote chased down before lunch, the quiet half-hour with an old book that you keep returning to. It is a theme for Obsidian, for Typora, and for the small websites where people still write in paragraphs. It is not a theme for dashboards or for screens that need to shout.

The name comes from the Greek. To the ancients, νοῦς was the faculty of the mind that simply sees — the part that recognizes a truth before it has finished proving it. That is the kind of attention this theme is made for. Not the scroll, but the pause.

ἐν ἀρχῇ ἦν ὁ λόγος In the beginning was the word.

Its colors come from a single afternoon: the limestone of a half-ruined temple, warmed by the sun; the small blue of the sea through the columns; the olive that grows indifferent to history on the hillside. Nothing saturated, nothing that wants to be looked at before the words are.

Its typography is drawn from the printed book. Headings in Cormorant Garamond, set wide and unhurried. Body in EB Garamond, old-style figures, real italics, ligatures on. A monospace (JetBrains Mono) only when code demands it — and then set a full size down, so it knows it is a guest. Greek sits in GFS Didot, upright and calm.

What you will find here is a system of small decisions, all in the same direction: toward the reader, and away from the interface. If the theme is doing its work, you will not notice it after the first paragraph. You will notice only that you kept reading.

Chapter IILight & Stone

Chapter II

Light & Stone.

Eight colors, all of them drawn from the same hillside — the limestone at noon, the sea through the colonnade, the pot at the market, the olive that refuses to hurry.

Nous——νοῦς——是希腊语里"心智之眼"。它不属于争辩，也不属于感官，而属于那一瞬间的看见：如同一道光穿过石柱的缝隙，恰好落在你翻开的书页上。

这套主题为此刻而设计。它不为仪表盘，不为通知，不为任何需要被立刻看见的东西。它只为那半个小时的独处，为一段注脚的追溯，为一句反复读过的诗行——为阅读本身。

Body · Emphasis

Philosophy begins in wonder — in the moment we look up from what we were doing and ask, with some surprise, what it was we thought we were doing. Aristotle called this thaumazein, and thought the whole of the examined life unfolded from it.

The unexamined sentence, like the unexamined life, is not worth writing.

Blockquote

The beginning is the most important part of the work.

We are what we repeatedly do. Excellence, then, is not an act, but a habit.

论习惯

——我们是自己反复所为之事。

亚里士多德在《尼各马可伦理学》开篇便提醒我们：善并非偶然之举，而是习惯的果实。一个公正之人，不是在审判时才公正，而是在不被看见时仍然如此。

卓越不是一次行动，而是一种习惯。

Footnotes · Horizontal Rule

The soul, on Aristotle's account, is not a thing a body contains but the form of a living body1. That is why the soul cannot outlive the body in any simple way — it is what the body is doing when it is alive2.

This is a different matter from Plato's. For Plato, the soul is prior to the body and separable from it; the body is the chariot, the soul the charioteer3.

  1. De Anima, II.1. "The soul is the first actuality of a natural body which has life potentially."
  2. Hence Aristotle's difficulty with personal immortality — a difficulty the Neoplatonists would later labor to relieve.
  3. See Phaedrus, 246a — the famous myth of the charioteer and the two horses.

On Becoming

A note on γίγνεσθαι — coming-to-be — and why the river is not a metaphor.

Heraclitus is supposed to have said that one cannot step into the same river twice. The line is nearly always quoted as if it were a small poetry about impermanence. It is stranger than that. The river, in his argument, is not an illustration of becoming — it is a case of it. What a river is, is the running.

Into the same rivers we step and do not step; we are and are not.

Heraclitus · DK 22 B49a

Two kinds of sameness

A [[river]] is the same across time in one way; its water is different in another. Aristotle, reading this two centuries later, made the distinction sharp: the river has a form that persists, and a matter that does not. See also #form-and-matter.

Aside

Compare Theseus' ship — the same problem, posed as a puzzle rather than a principle.

On the Forms

That the things we point at are not the things we mean.

When a geometer draws a triangle, he is not, in the serious sense, drawing a triangle. He is drawing three approximate lines which, taken together, stand in for a triangle — which itself has no edge one could point at, no chalk to it, no paper. What he reasons about is the figure; what he draws is the occasion.

The knowledge at which geometry aims is knowledge of the eternal, and not of anything perishing and transient.

Plato · Republic, VII.527b

The ladder

This is the small staircase the Symposium makes famous. From one body to many, from bodies to institutions, from institutions to the sciences, and from the sciences to the beautiful itself — αὐτὸ τὸ καλόν. At each step the object loses something in particularity and gains something in permanence.

Editorial note

The English "Form" is a bad loan for εἶδος, which in ordinary Greek simply means "look" or "shape." Something less grand would translate better; nothing less grand has stuck.

Set against this is the harder Aristotelian question — whether the form of a thing is in fact separable from it at all, or whether "triangle" is only ever the shape of some particular triangle, however poorly drawn1.

I will take this up in the next entry. For now it is enough to say: the quarrel is old and the quarrel is still live.

  1. See Metaphysics, Ζ.13 — the argument against Platonic forms considered as separate substances.

The Afternoon, and What It Asks of Us.

In which we consider reading as a kind of hospitality, and the page as a room.

Some books are doors and some books are windows. A door you walk through once; a window you return to. I have been thinking lately about which kind of thing a website is — whether, in the way most of them are made, they can be either, or whether they are something else again, something closer to a hallway one passes through on the way somewhere more interesting.

The honest answer is that most of them are hallways, and know it. But a few are rooms, and know that too. This is an essay for the people who would like to make rooms.

Beauty is the harvest of what the attention loves. If we want beauty, we must love what we attend to; if we want truth, we must attend to what we love.

Simone Weil, paraphrased

What a room is for

A room, unlike a hallway, is not for getting anywhere. It is for sitting, for reading, for the conversation that does not have a destination. The best pages on the web are rooms — the ones where someone has clearly swept the floor, set the chair at the right distance from the window, and left a book on the table in case you arrived early.

A hallway-page, by contrast, is designed to be left. Every pixel in it is trying to hand you off to the next pixel. Its headings are captions; its captions are calls-to-action; its articles are introductions to its newsletters; its newsletters advertise its articles. It is not a building, quite; it is the interior of a logistics problem.

Three small mercies

This is not an essay about how the web went wrong. It is an essay about three small things a page can do, today, to be a little more like a room. I will list them and then spend the rest of our afternoon on each:

  1. Set the measure correctly, and leave it alone.
  2. Let type do its work, and resist the urge to help.
  3. Make the quiet parts — the margin, the folio, the rule — mean something.

For later

Compare Bringhurst on the page as "the living room of the printed word" — a phrase I have never improved on, only found occasions for.

We will take them in order, and we will not be in any hurry.
