The Nature of Beauty
I died for beauty
The quality without a name
My own beauty reflected
On beauty bare
The Abode of Vacancy
The Abode of the Unsymmetrical
He only who has lived with the beautiful
The core assertion
Restrained beauty
A sense reflected in the plans
A world with pyramids
Which would you choose—
a world with pyramids,
or a world without?White cloth
I used to be very interested in the fact that anything, no matter how rough, rusted, diffy, or otherwise discredited it was, looked good if you set it down on a stretch of white cloth. Because anytime you set some detail of the world off that way, it was able to take on its true stature as an object of attention.
Ordinariness
We have a habit of thinking that the deepest insights, the most mystical, and spiritual insights, are somehow less ordinary than most things - that they are extraordinary.
In fact, the opposite is true: the most mystical, most religious, most wonderful – these are not less ordinary than most things – they are more ordinary than most things. And it is because they are so ordinary, indeed, that they strike to the core.
To deprecate beauty itself
One can gain a glimpse of the quality of a people’s life by the kind of paper they use for writing letters, for literary works, and for various other tasks. Paper should not be deprecated. To do so is to deprecate beauty itself.
A Painted Karatsu as Food for Thought
Recently there is a tendency to pursue distortion in art, but in the case of this jar, natural deformation has raised distortion to the level of spontaneous beauty.
That one thing against another creates
Such is our way of thinking—we find beauty not in the thing itself but in the patterns of shadows, the light and the darkness, that one thing against another creates.
If I can't be beautiful
Howl: I give up...I see no point in living if I can't be beautiful.
A grave and noble beauty
An architecture of our own age is slowly but surely shaping itself; its main lines become more and more evident. The use of steel and reinforced concrete construction; of large areas of plate glass; of standardized units (as, for example, in metal windows); of the flat roof; of new synthetic materials and new surface treatments of metals that machinery made possible; of hints taken from the airplane, the motor-car or the steamship where it was never possible, from the beginning, to attack the problem from an academic standpoint—all these things are helping, at any rate, to produce a twentieth-century architecture whose lineaments are already clearly traceable. A certain squareness of mass and outline, a criss-cross or “grid-iron” treatment with an emphasis on the horizontals, an extreme bareness of wall surface, a pervading austerity and economy and a minimum of ornament; these are among its characteristics. There is evolving, we may begin to suppose, a grave and classical architecture whose fully developed expression should be of a noble beauty.
How beautiful the world would be if there were a procedure for moving through labyrinths
Salk Institute for Biological Studies, La Jolla, 1959–65
If you are there at sunset, as are the scientists every day, you see the most magical of transformations: the golden glow that fills the sky to the west is first reflected in the water of the ocean and then shoots like a line of fire up through the gathering darkness of the plaza's stone floor, to reach its source in the cubic fountain. The court is breathtaking in its sublime power, opening at the edge of the continent to the Pacific Ocean and framing the light blue-on-dark-blue horizon line of the sea and sky.
The Caspian
The Caspian has its realms of sand,
Its other realm of sea;
Without the sterile perquisite
No Caspian could be.The quality of the day
It is something to be able to paint a particular picture, or to carve a statue, and so to make a few objects beautiful; but it is far more glorious to carve and paint the very atmosphere and medium through which we look, which morally we can do. To affect the quality of the day, that is the highest of arts.
Fucking up the world
City Hall by Rafael Moneo, Logroño, La Rioja, Spain.
Alexander : At least my experience tells me, that when a group of different people set out to try and find out what is harmonious, what feels most comfortable in such and such a situation, their opinions about it will tend to converge, if they are mocking up full-scale, real stuff. Of course, if they're making sketches or throwing out ideas, they won't agree. But if you start making the real thing, one tends to reach agreement. My only concern is to produce that kind of harmony.
The thing that strikes me about your friend's building – if I understood you correctly – is that somehow in some intentional way it is not harmonious. That is, Moneo intentionally wants to produce an effect of disharmony. Maybe even of incongruity.
Eisenman: That is correct.
Eisenman: I find that incomprehensible. I find it very irresponsible. I find it nutty. I feel sorry for the man. I also feel incredibly angry because he is fucking up the world.
It will not stand still to be pointed at
The cause of the experience of beauty is a series of events, not a state of affairs existing continuously. That perhaps is why the cause of the experience is something we find impossible to point out. It will not stand still to be pointed at. We can point out only what we perceive. We can never point out or describe what we see.
A curious fact
Is it not a curious fact that in a world steeped in irrational hatreds which threaten civilization itself, men and women — old and young — detach themselves wholly or partly from the angry current of daily life to devote themselves to the cultivation of beauty, to the extension of knowledge, to the cure of disease, to the amelioration of suffering, just as though fanatics were not simultaneously engaged in spreading pain, ugliness, and suffering? The world has always been a sorry and confused sort of place — yet poets and artists and scientists have ignored the factors that would, if attended to, paralyze them. From a practical point of view, intellectual and spiritual life is, on the surface, a useless form of activity, in which men indulge because they procure for themselves greater satisfactions than are otherwise obtainable.
Some emptiness in us
Whenever we encounter beauty we become aware, each time with a sense of shock and pleasure, faint though it may be, that some emptiness in us, not consciously felt but continually present, has been assuaged and fulfilled. We have a sudden high sense of completeness and harmony.
The matrix of all we know
Man's species has existed for an immensely longer period, unimaginably longer, in an unmodified natural environment. That unmodified environment was the matrix of all man knows of beauty. All the means of his experience of beauty evolved in it. Now, in the artificial environment, art creates an equivalent for that beauty, for it is a need of man's spirit.
Who did the teaching, then?
It has been contended sometimes that our response to works of art is entirely learnt and in no way innate; but the questions 'Who did the teaching, then? and how?' have not, I fancy, been much investigated. This contention is very true of our responses to styles and fashions, but it is not true of our response to beauty.
No kind
No kind of shape, no kind of design or kind of picture or other work of art can be beautiful. No kind of color is beautiful. Beauty comes always from the singularity of things. Two things which happen to be closely similar in size, color, insurance value, smell, weight, or shape, may both seem equally beautiful. It is not therefore to be deduced that, say, a smell of turpentine is a necessary prerequisite of beauty; and nor is the fact that the two things' shapes are measurably within a millimeter of each other. They might still be as different as chalk and cheese: they might differ hugely in surface quality so that one lived and the other was dead. One judges a man by what he is, by his individuality, his idiosyncrasy; not by his measurable properties or measurable behavior or by the shape of his nose or the description in his passport. So with a work of art.
Ideas of a good life
In essence, what works of design and architecture talk to us about is the kind of life that would most appropriately unfold within and around them. They tell us of certain moods that they seek to encourage and sustain in their inhabitants. While keeping us warm and helping us in mechanical ways, they simultaneously hold out an invitation for us to be specific sorts of people. They speak of visions of happiness.
To describe a building as beautiful therefore suggests more than a mere aesthetic fondness; it implies an attraction to the particular way of life this structure is promoting through its roof, door handles, window frames, staircase, and furnishings. A feeling of beauty is a sign that we have come upon a material articulation of certain of our ideas of a good life.
Inwardly to resemble
What we want, at the deepest level, is inwardly to resemble, rather than physically to possess, the objects and places that touch us through their beauty.
We can conclude from this that we are drawn to call something beautiful whenever we detect that it contains in a concentrated form those qualities which we personally, or our societies more generally, are deficient.
The extremes of order and complexity
Such works emphasize the truth of the ancient maxim that beauty lies between the extremes of order and complexity.
It follows that the balance we approve of in architecture, and which we anoint with the word ‘beautiful’, alludes to a state that, on a psychological level, we can describe as mental health or happiness. Like buildings, we, too, contain opposites which can be more or less successfully handled.
Beauty and strength
Yet the bridge testifies to how closely a certain kind of beauty is bound up with our admiration for strength, for man-made objects which can withstand the life-destroying forces of heat, cold, gravity or wind.
We respond with emotion to creations which transport us across distances we could never walk, which shelter us during storms we could not weather, which pick up signals we could never hear with our own ears and which hang daintily off cliffs from which we would fall instantly to our deaths.
With grace and economy
Both bridges accomplish daring feats, but Maillart’s possesses the added virtue of making its achievement look effortless - and because we sense it isn’t, we wonder at it and admire it all the more. The bridge is endowed with a subcategory of beauty we can refer to as elegance, a quality present whenever a work of architecture succeeds in carrying out an act of resistance - holding, spanning, sheltering - with grace and economy as well as strength; when it has the modesty not to draw attention to the difficulties it has surmounted.
Needs more love
He held the phone to his chest, looked at me, and simply said, “Needs more love.” He pushed the portfolio back across his desk, smiled warmly, and shooed me out of his office.
I still think about this advice, and what exactly he might have meant when he said my work needed more love. At the time, I took it to mean that I should improve my craft, but I’ve come to realize that he was speaking of something more fundamental and vital. My work was flat, because it was missing the spark that comes from creating something you believe in for someone you care about. This is the source of the highest craft, because an affection for the audience produces the care necessary to make the work well.
We hear a voice whisper
The Shakers have a proverb that says, “Do not make something unless it is both necessary and useful; but if it is both, do not hesitate to make it beautiful.” We all believe that design’s primary job is to be useful. Our minds say that so long as the design works well, the work’s appearance does not necessarily matter. And yet, our hearts say otherwise. No matter how rational our thinking, we hear a voice whisper that beauty has an important role to play.
Praise has no part in it
Everything that is in any way beautiful is beautiful of itself and complete in itself, and praise has no part in it; for nothing comes to be better or worse for being praised.
When a building has this fire
And when a building has this fire, then it becomes a part of nature. Like ocean waves, or blades of grass, its parts are governed by the endless play of repetition and variety, created in the presence of the fact that all things pass. This is the quality itself.
The gate
To reach the quality without a name we must build a living pattern language as a gate.
True artistry
The best of all examples of a satisfactory art form based upon the inner nature of a metal is provided by Japanese swords.
Our perception of beauty seems to involve the interaction of several patterns having origin and significance at many different levels of space, time, matter, and spirit. In the Japanese sword blade there is heterogeneity in both the macrostructure and the microstructure. The manner of forging, the heat treatment, and the final polishing operation are all uniquely Japanese techniques, and all make necessary contributions to the final quality of the blades. The shape along would be simplistic form; the forged texture of the steel without heat treatment would at best faintly echo the beauty of grained wood; the outlines of the quench-hardened zone at the edge would be sharp and uninteresting if it depended only on the control of cooling rate during quenching; and the polish would be uniform glitter if the metal were homogeneous. With true artistry all these are made to interact.
What we are accustomed to call beautiful
Most objects which we are accustomed to call beautiful, such as a painting or a tree, are single-purpose things, in which, through long development or the impress of one will, there is an intimate, visible linkage from fine detail to total structure.
Grace
Grace: you work and you work and you work at something that then happens of its own accord. It would not have happened without all that work, but the result cannot be accounted for as the product of the work in the sense that an effect is said to be the product of its causes. There is all that preparation—preparation for receptivity—and then there is something else beyond that, which is gratis, for free.

A Book by Christopher AlexanderAI-art isn’t art
An Essay by Erik HoelAI-generated artwork is the same as a gallery of rock faces. It is pareidolia, an illusion of art, and if culture falls for that illusion we will lose something irreplaceable. We will lose art as an act of communication, and with it, the special place of consciousness in the production of the beautiful.
…Just as how something being either an original Da Vinci or a forgery does matter, even if side-by-side you couldn’t tell them apart, so too with two paintings, one made by a human and the other by an AI. Even if no one could tell them apart, one lacks all intentionality. It is a forgery, not of a specific work of art, but of the meaning behind art.
Good Things
A Website by Melanie RichardsAgainst the survival of the prettiest
An Essay by Samuel HughesWhat has emerged here is that although survivorship bias probably does contribute to that to some extent, it is not the main explanation: premodern buildings may on average have been a bit less beautiful than those that have survived, but they still seem to have been ugly far less often than recent buildings are.
The survivorship theory sought to explain the apparent rise of ugliness in terms of a bias in the sample of buildings we are observing. There is another kind of bias theory, which seeks to explain it in terms of a bias in the observer, saying for instance that every generation is disposed to find recent buildings uglier than older ones, and that this is why recent buildings seem so to us. This is a complex and interesting idea, which I am not going to assess on this occasion. Suppose, though, that our eyes are to be trusted. If this is so, strange and eerie truths rise before us: that ugly buildings were once rare, that the ‘uglification of the world’ is real and that it is happening all around us.
In search of visual texture
An Article by Rachel PruddenI’m now more inclined to attribute Looseleaf’s power to its visual texture than to some cognitive media-style abstraction. And the visual texture owes more to the beauty (yes, beauty!) of the original pdfs from the Vasulka Archive. Perhaps the demo is best understood not as a prototype generic tool, but as a specific curated experience in its own right, with form and content claiming equal importance in its overall success.
Even so, I think there are some general lessons that can be drawn from this demo:
- Content is not inert
- Visual texture lets content breathe
- Visual texture lets the eye wander without losing itself
Beauty and compression
An Article by Scott AlexanderThe Buddha discusses states of extreme bliss attainable through meditation:
Secluded from sensual pleasures, secluded from unwholesome states, a bhikkhu enters and dwells in the first jhāna, which is accompanied by thought and examination, with rapture and happiness born of seclusion.
...If you could really concentrate on a metronome, it would be more blissful than a symphony. The jhāna is also a strong contender as a theory of beauty: beauty is that which is compressible but has not already been compressed.

An EpisodeIn this episode, we talk about the work of architect, builder, and design theorist Christopher Alexander. Joining us are two of Alexander’s former students, Susan Ingham and Chris Andrews. They talk about their philosophy of architecture and their program, Building Beauty, which offers a post-graduate diploma in architecture based around Alexander's ideas.

Taste for Makers
An Essay by Paul GrahamIf there is such a thing as beauty, we need to be able to recognize it. We need good taste to make good things. Instead of treating beauty as an airy abstraction, to be either blathered about or avoided depending on how one feels about airy abstractions, let's try considering it as a practical question: how do you make good stuff?

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

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."

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.
