About

Seen Again is a set of essays about how people think, written for anyone who has ever looked at an ordinary thing a second time and seen more than was there.

What this site is for

The site argues for something modest and useful: the level at which you think changes what you can see, and you can choose that level deliberately. Most difficulty in teaching, designing, building and studying is not a shortage of effort. It is a mismatch between the level of attention a situation needs and the level of attention being brought to it.

So the essays take one ordinary object at a time. A cup. A queue. A door. A clock. They walk it up through five levels of description, and then they ask what the walk left out. The hope is not that the model is correct. The hope is that it gives you something to try on a real case.

Who it is for

Curious adults. Teachers, designers, founders, students, makers. No prior knowledge is assumed, and no term is used before it is defined. The writing assumes you are willing to think about your own thinking, which is the only prerequisite that cannot be taught in advance.

How to read it

Start with The Cup on the Table, which introduces the model by taking one object apart. Then read Which Lens, and When, which is about choosing. After that the ladder page is a map of the whole argument, and the Field Guide turns it into six questions you can ask yourself about your own current problem.

Each essay ends with one exercise you can do today in under fifteen minutes. All of them are collected on the practice page.

The limits of the model

The five levels are a working model, not established science, and they are not a faithful summary of any existing framework. They are lenses, not rungs. Higher is not better. The order is a teaching convenience rather than the way situations actually unfold. The ladder page sets out these weaknesses in more detail, and several essays have a section on where their own idea stops working.

Colophon

Set in IBM Plex Serif for body text, IBM Plex Sans for headings and navigation, and IBM Plex Mono for labels, captions and figure numbers. The palette is a warm paper ground with ink, and five level colors that always mean the same level on every page and in every diagram: ochre for tangible, green for abstract, blue for principle, violet for system, teal for loop, and vermilion for the judgment that sits above the ladder.

Built as plain HTML, CSS and SVG with no JavaScript, no tracking and no cookies, and hosted on Cloudflare Pages. Every diagram is hand-authored SVG that carries exactly one message. A RSS feed is available for readers who prefer one.
