The quality of thought
Walking is a natural armature for thinking sequentially

Let the body wander
If the mind needs to wander, best let the body do the same. A short walk is more effective in coming up with an idea than pouring all the coffee in the world down your gullet.
Agents of thought and experiment
The act of drawing serves to remind us that hands are agents of thought and experiment. Photography has a great future, but no matter how much ancillary wizardry photography accumulates, it will not be in competition with “drawing” in the broadest sense of that term. There will always be a role for exploration by the hands, encumbered by no more than a piece of ocher or a stick of charcoal.
Its practical utility is as a manifestation of the mind struggling with the meaning of what it encounters and what it wants to explore.
For one who can see
Hundreds of people can talk for one who can think, but thousands can think for one who can see.
A blue glow
The neurons that do expire are the ones that made imitation possible. When you are capable of skillful imitation, the sweep of choices before you is too large; but when your brain loses its spare capacity, and along with it some agility, some joy in winging it, and the ambition to do things that don't suit it, then you finally have to settle down to do well the few things that your brain really can do well - the rest no longer seems pressing and distracting, because it is now permanently out of reach. The feeling that you are stupider than you were is what finally interests you in the really complex subjects of life: in change, in experience, in the ways other people have adjusted to disappointment and narrowed ability. You realize that you are no prodigy, your shoulders relax, and you begin to look around you, seeing local color unrivaled by blue glows of algebra and abstraction.
Get a grip
The hand is the window on to the mind. — Immanuel Kant
American slang advises us to "get a grip"; more generally we speak of "coming to grips with an issue." Both figures reflect the evolutionary dialogue between the hand and the brain.
In a stare
Being in a stare referred to staring fixedly and without expression at something for extensive periods of time. It can happen when you haven't had enough sleep, or too much sleep, or if you've overeaten, or are distracted, or merely daydreaming. It is not daydreaming, however, because it involved gazing at something. Staring at it. Usually straight ahead—a shelf on a bookcase, or the centerpiece on the dining room table, or your daughter or child. But in a stare, you are not really looking at this thing you are seeming to stare at, you are not even really noticing it—however, neither are you thinking of something else. You in truth are not doing anything, mentally, but you are doing it fixedly, with what appears to be intent concentration. It is as if one's concentration becomes stuck the way an auto's wheels can be stuck in the snow, turning rapidly without going forward, although it looks like intense concentration. And now I too do this.
The Ladder of Abstraction
An Essay by Bret VictorPensées
A Book by Blaise PascalOn online collaboration and our obligations as makers of software
An Essay by Baldur BjarnasonIs it the notetaking system that’s helping you think more clearly? Or is it the act of writing that forces you to clarify your thoughts?
Is it the complex interlinked web of notes that helps you get new ideas? Or is it all the reading you’re doing to fill that notetaking app bucket?
Is all of this notetaking work making you smarter? Or is it just indirectly forcing you into deliberate, goalless practice?

e-worm.club
A Website by Zach ShermanI’m building a custom pleroma client so that my friends and I can have a cute, self-hosted social network to post about politics and art. Besides being much more visually interesting than our facebook messenger groupchat, e-worm also attempts to solve design problems around conversational, collaborative thinking. The biggest of these problems is the inherent ephemerality of our groupchat— it doesn’t really succeed as a collaborative thinking space because it has no long-term memory. When messages are constantly buried under new ones, it places the burden on us to remember previous conversations. So the ultimate design goal for e-worm is to create a self-archiving conversational interface that preserves thought and helps us keep thinking new things rather than going in intellectual circles.
The surprising effectiveness of writing and rewriting
An Article by Matt Webb- The act of writing the first draft creates new “essential data” that feeds the imagination and makes possible figuring out the second draft.
- Or: In your head, ideas expand until they max out “working memory” – and it’s only be externalising them in the written word that you have capacity to iterate them.
- Or: Good writing necessarily takes multiple edits, and the act of writing and act of rewriting are sufficiently different that performing both simultaneously is like rubbing your tummy and patting your head.
How can we develop transformative tools for thought?
A Research Paper by Andy Matuschak & Michael NielsenConventional tech industry product practice will not produce deep enough subject matter insights to create transformative tools for thought.
...The aspiration is for any team serious about making transformative tools for thought. It’s to create a culture that combines the best parts of modern product practice with the best parts of the (very different) modern research culture. You need the insight-through-making loop to operate, whereby deep, original insights about the subject feed back to change and improve the system, and changes to the system result in deep, original insights about the subject.

On the Link Between Great Thinking and Obsessive Walking
An Article by Jeremy DeSilvaYou are undoubtedly familiar with this situation: You’re struggling with a problem—a tough work or school assignment, a complicated relationship, the prospects of a career change—and you cannot figure out what to do. So you decide to take a walk, and somewhere along that trek, the answer comes to you.

An EssayZettelkasten
A Tool by Niklas LuhmannA zettelkasten consists of many individual notes with ideas and other short pieces of information that are taken down as they occur or are acquired. The notes are numbered hierarchically, so that new notes may be inserted at the appropriate place, and contain metadata to allow the note-taker to associate notes with each other. For example, notes may contain tags that describe key aspects of the note, and they may reference other notes. The numbering, metadata, format and structure of the notes is subject to variation depending on the specific method employed.
That the mind may not be taxed
A Quote by Thomas FarnabyIn order that the mind may not be taxed, moreover, by the manifold and confused reading of so many such things, and in order to prevent the escape of something valuable that we have read, heard, or discovered through the process of thinking itself, it will be found very useful to entrust to notebooks...those things which seem noteworthy and striking.

The problem with trees
Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as:
HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS
only to find a reference to another leaf: Please see
HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS
and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.
Content-responsive space
Content-responsive spaces in text can be as meaningful as spaces and line breaks in computer code, poetry, math, dialogues, cartoons.
For 1500 years, printed text has used grids indifferent/hostile to meaning. Content-responsive grids are better than imperious grid-possessed layouts. To clarify and intensity meaning, authors and editors can remodel relations between spaces and words...insisting on control of line breaks by authors (who, after all, know the content).
Personal annotations
Yehudi Menuhin, a great violinist, marked up a score for Bach's Sonata No. 2 for Solo Violin. Penciled annotations show real-time performance strategies. To outsiders, insider markups appear chaotic and cryptic, but these personal annotations are for Menuhin's eyes, the only eyes that matter. All can learn from this useful workaday grid strategy: a relevant and intense data layer can become a coherent substrate scaffold upon which to overlay additional information. Maps do this all day long.
What excellence is
Learn what excellence is, how to identify it...This is not a big reading assignment – excellence is scarce, lognormal, long-tailed. Acting on this knowledge is liberating, freeing oneself from vast piles of triviality, knock-offs, petty connoisseurship, over-publishing, and the short-sighted, trendy, greedy. Excellence is long-term knowledge, even forever knowledge.
Excellence, like good taste, is perhaps a universal quality. Analytical thinking is about the relationship between evidence and conclusions, and is fundamental to all empirical work, regardless of field, discipline, specialty. Thus it is possible at times to assess credibility of nonfiction work without being a content expert. Thinking eyes may well have an eye for excellence, regardless of field or discipline.
Sentences and words do not exist by themselves
Sentences and words do not exist by themselves, but have natural, inevitable, unavoidable interactions with their surrounding spaces, words, and other sentences. Sentences are not independent of their spatial context, and interactions can create meanings and harms. Sentences survive content-indifferent and content-hostile spacings, but surviving is not thriving. Text space should not be owned and governed by generic productions grids, which make for convenient production but inconvenient meaning. Space can and should be content-responsive, actively contributing to meaning – forever practices in poetry, maps, math, computer code, comics, theater/movie scrips, posters. Subtle visual spacing differentiates and clarifies sentences, and meaning becomes more consequential, memorable, retrievable.
Central-axis text
Central-axis provides a clear signal of the next line, so that readers and speakers don't have to search on the left margin, sometimes accidentally skipping down a line. Ragged-left typography is used for dialogue in novels and scripts. In central-axis, each line is activated at both left and right margins – unlike squared-off conventional text. Readers/speakers are aware of the length of the next line at both its beginning and end. That knowledge may also help readers detect the pace and rhythm of the words, as in reading poetry aloud.
Idiosyncratic paragraphs
Text-only paragraphs differ from one another only in their words. All the words are typographically the same – typeface, spacings, line-lengths piled up into long deep columns. Systematic regularity of text paragraphs is universally inconvenient for readers, who are unable to find and read once against a specific string of words in previously-read paragraphs. All readers have encountered this problem in essays, articles, novels, news reports. Idiosyncratic paragraphs assist memory and retrieval by readers, by uniquely activating the relevant neural substrates for retaining visual memories. Nearly every paragraph in this book is deliberately unique.
No more LittleDataGraphics
Small data sets should be shown directly...LittleDataGraphics (pie charts, bar charts) translate and encode data into areas and colors. Viewers must then mentally translate codes back into numbers. These codes are unique to the local sets of data graphics, and do not repay learning. Instead, just directly show numbers as numbers. No more LittleDataGraphics. Data visualizations are at their best when there is so much data that the only way to see it...is to see it.
An immense wordy diagram
In ~1560 Ettore Ausonia, a polymath with interests from mathematics to mirror-making, constructed an immense wordy diagram depicting reflections from concave spherical mirrors. Then, between 1592 and 1601, while teaching at the University of Padua, Galileo made this handwritten copy of the diagram, which was fortunate since Ausonio's original has since gone missing. Three helpful architectures for the off-the-grid sentences are deployed – word trees, stacklists, annotated linking lines.
Stacklists
Stacklists organize and clarify complex material in 2-space. Readers read more slowly, and that's good: to think, look again, and connect words vertically within each stack and horizontally between stacks. Instead of polyphony, conventional inline lists are a freight train of words along a one-way narrow track, making it difficult to identify which words belong to which list and to link and compare elements within and between lists.
Observe data collection at the moment of measurement
See, observe, learn how data are collected at moment and place of measurement. "You never learn more about a process than when you directly observe how data are actually measured," said Cuthbert Daniel, a superb applied statistician. See with fresh eyes. Walk around what you want to learn about. Talk to those who do measurements. See how numbers came to be.
Do those measuring know the desired answer? Are those measuring skilled, alert, honest, biased, incompetent, sloppy, tired and emotional?...Artifacts and errors in measurements measured? How are outliers adjudicated?

Outcomes decide
High levels of U.S. patient satisfaction are mainly associated with hospitality (greeters at the door, empathetic staff, comfortable rooms) – but also with more treatments, high costs, and substantially higher mortality even after adjusting for baseline health and comorbidities. Several plausible stories explain these big n and replicated observational findings. Whatever the case, post-treatment patient satisfaction/gratitude does not measure whether a treatment works or not. Patient outcomes decide.
Which half?
One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?"
Good annotation
Information displays should be annotated, combining words, images, graphics, whatever it takes to describe and explain something. Annotation calls out and explains information and, at the same time, explains to viewers how to read data displays. Good annotation is like a knowledgeable expert/teacher at the viewer's side pointing and saying, "Now see how this works with that, how this might explain that..."
Signs seen and unseen
Direct instructions at point of need may encourage writers and programmers to divert diversions. Or not, because signs are seen only a few times before becoming unseen.
What is the strongest visual element?
Preparing to write the novel Catch 22, Joseph Heller composed a storyboard, a 2-dimensional list with 3,650 words arrayed in 34 × 21 = 714 interacting cells. Rows are ordered in time, and each row records when each character does what. Some cell entries are erased. It took 7 years to complete the novel's 758-page typescript.
The Catch 22 plotchart works better upon replacing optically noisy grids with ghost grids. Lightness of framing lines creates soft boundaries to maintain order and also allows words to spill across cells naturally...More generally, ask of information displays and interfaces, "What is the strongest visual element?" The correct answer is not "grid lines".
Your only language is vision
To see with fresh, uninstructed eyes and an open mind requires a deliberate, self-aware act by the observer. Abstract artworks represent themselves and should be first viewed for themselves. When looking at outdoor abstract pieces, concentrate initially on the unique optical experience produced by the artworks. See as the artist saw when making the piece.
A focus on optical experience does not deny stories, it postpones them. Viewing an artwork may evoke interesting narratives – or just tedious artchat recalling similar art or artists, concocting playful tales, realizing how scrap metal was repurposed into art, making judgments about the artist's intentions or character, or contemplating an artwork's provenance, price, politics. Let the artwork stand on its own. Walk around fast and slow, be still, look and see from

Lists consist of whatever it takes – nouns, proper nouns, verbs, graphics, images, numbers.
...In lists, spaces have meaning, locating elements in relation to other elements. Lists are often free and independent from conventional rules of stylesheets / grammar / typography / punctuation. Lists also help us escape from the personal internalized mash-up stylesheets of every writer and reader – a continuous low-level background buzz checking to see if word usage, spelling, punctuation, grammar are 'correct'. Lists are all content – about the substance contained, not the container. An empirical theory here for reasoning about lists includes
selection of list items
list quality and completeness
comparing list models
comparing list architecturesNo wonder you think it's complicated
We were very proud of our user interface and the fact that we had a way to browse 16,000 (!!) pages of documentation on a CD-ROM. But browsing the hierarchy felt a little complicated to us.
So we asked Tufte to come in and have a look, and were hoping perhaps for a pat on the head or some free advice. He played with our AnswerBook for 90 seconds, turned around, pronounced his review:
"Dr. Spock's Baby and Child Care is a best-selling owner's manual for the most complicated 'product' imaginable – and it has only 2 levels of headings. You have 8 levels of hierarchy and I haven't stopped counting yet. No wonder you think it's complicated."
Verb List
Documents vs. decks
Decks are easier to prepare than documents, however. Documents require coherence, thinking, sentences. But convenience in preparing decks harms the content and the audience. Optimizing presenter convenience is selfish, lazy, and worst of all, replaces thinking.
Books are meant to be used
During most of the course students have their books open, either to read or to follow along. Students are encouraged to annotate the books: "Books are meant to be used. Dog-ear the pages, mark them up, put notes in the spacious margins."
Learning via teaching
The course material changes 15% each year, as the book currently in progress becomes part of the course years before it is finally published. I detect incoherencies and mistakes in the new material while teaching. This leads to refinements or even throwing stuff out from the forthcoming book. A good way to learn about something is to teach it.
Self-publishing, self-exemplifying
I sought to design [my first book] so as to make it self-exemplifying – that is, the physical object itself would reflect the intellectual principles advanced in the book. Publishers seemed appalled at the prospect that an author might govern design. Consequently I decided to self-publish the book.
...[Howard Gralla and I] spent the summer in his studio laying out the book, page by page. We integrated graphics into the text, sometimes in the middle of sentences, eliminating the usual segregation of text and image – one of the ideas Visual Display advocated.
My view on self-publishing was to go all out, to make the best and most elegant and wonderful book possible, without compromise. Otherwise, why do it? The next 4 books were financed by the previous books. I have never written a grant application.
A history of content and sources
Not all that many readers go to the back matter and look up the source for a single sentence. But the back matter can also be read as ordinary text, revealing a history of content and sources. And images and illustrations from the book in the back matter create a lovely visual/verbal summary quilt of the entire book, enjoyed by all.
