Perception & Senses
A kind of moiré pattern
Who's Afraid of Red, Yellow, & Blue^3
Art as art
If modern painting is "art as art," this means, to paraphrase Reinhardt, that is represents nothing and exists only in and for itself. If this has created an "art language, with an art communication," this is because this kind of art has implied all along a form of intimate contact with its viewer, in which the viewing of "art as art" becomes "sensation as sensation" or "perception as perception." This distinguishes "modern painting" from representational painting, which exhibits duality, that is, it uses imagery to refer to "past experiences and feeling," and to "color and reconstruct in the mind" associations that are meaningful, but that take the viewer far away from the specifics of the encounter with the painting before them.
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

The structure of matter devolved ultimately into the intimate coexistence of something like corpuscles of nothing and atoms of something, segregating through the accidents of history to yield regions differing in density intimately interwoven on different scales. The experience of the world as well as human perception and analysis of any part of it is a matter of the angular scale of resolution and of the time necessary for making comparison between the different parts.
Without such variations and without time to compare remembrances of them, nothing can be experiences.
The skill of perception
The newborn baby and the [blind man suddenly gifted with sight] do not have to learn to see. Sight is given to them. But they do have to learn to perceive. Perception is learnt and learnt slowly. Skill is required for perception as for speech. We are largely unaware of the skill we exercise. None of the things we have to learn to perceive are self-evident, or, apparently, instinctively evident. No doubt, however, we have an instinctive aptitude for this learning, and once we have learnt we cannot easily see as though we had not.
As Ruskin says, one has to strive, if one is to see with the 'Innocent Eye'.
The innocence of the eye
The perception of solid form is entirely a matter of experience. We see nothing but flat colors; and it is only by a series of experiments that we find out that a stain of black or grey indicates the dark side of a solid substance... The whole technical power of painting depends on our recovery of what may be called the innocence of the eye; that is to say, of a sort of childish perception of these flat stains of color, merely as such, without consciousness of what they signify, as a blind man would see them if suddenly gifted with sight.
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.
Color reproduction
In-person, live observation of color is a practice for which I feel there is no adequate substitute. Photographs are often imprecise in reproducing color.
50 reds
If one says “Red” (the name of a color)
and there are 50 people listening,
it can be expected that there will be 50 reds in their minds.
And one can be sure that all these reds will be very different.Scotopic seeing
The sensitivity
and consequently the registration of the retina of an eye is different
from the sensitivity and registration of a photographic film.Normally, black-and-white photography registers all lights lighter
and all darks darker than the more adjustable eye perceives them.
The eye also distinguishes better the so-called middle grays,
which in photography are often flattened if not lost.This shows what a higher key in light can lose in photography.
The greatest advantage the eye has over photography
is its scotopic seeing in addition to its photopic seeing.
The former means, briefly, the retinal adjustment to lower light conditions.The Weber-Fechner law
Exponential increases in physical stimuli produce linear perceptual increases.
As plain as day
The personal experience of most of us will testify to this persistence of an illusory image long after its inadequacy is conceptually realized. We stare into the jungle and see only the sunlight on the green leaves, but a warning noise tells us that an animal is hidden there. The observer then learns to interpret the scene by singling out "give-away" clues and by reweighting previous signals. The camouflaged animal may now be picked up by the reflection of its eyes. Finally by repeated experience the entire pattern of perception is changed, and the observer need no longer consciously search for give-aways, or add new data to an old framework. They have achieved an image which will operate successfully in the new situation, seeming natural and right. Quite suddenly the hidden animal appears among the leaves, "as plain as day."
Three or more
"One and one don't make two, but maybe five or eight or ten, depending on the number of interactions you can get going in a situation."
There and not there
For what Bob was trying to capture in these efforts was the incidental, the transitory, the peripheral—that aspect of our experience that is both there and not there, the object and not the object of our sensations, perceived but seldom attended to.
Waiting there to be experienced
"Paintings are like what you can barely make out through a keyhole compared with the richness of perception that's just waiting there in the world to be experienced all the time. It's strange. With food, for instance, people seem able to understand what's involved: you savor the taste rather than just feed the body. But people have a hard time understanding that it should be the same way with visual experience."
The human reality of perception
"The great misinterpretation of twentieth-century art is the claim advanced that many people, especially critics, that cubism of necessity led to abstraction. But on the contrary, cubism was about the real world. It was an attempt to reclaim a territory for figuration, for depiction. Faced with the claim that photography had made figurative painting obsolete, the cubists performed an exquisite critique of photography; they showed that there were certain aspects of looking—basically the human reality of perception—that photography couldn't convey, and that you still needed the painter's hand and eye to convey them." — David Hockney

A Website by Leo RobinovitchSo some friends and I were talking about colors one day and how we all see colors a bit differently and how that's neat.
But is there a color that is interpreted differently THE MOST? Is there a most controversial color? Well, (if I contrive an ongoing survey and collect data about it), the answer is yes, of course!
The Craftsman
The great teacher
The good teacher imparts a satisfying explanation; the great teacher unsettles, bequeaths disquiet, invites argument.
The categories of good
We need to turn to a fresh page. We can do so simply by asking—though the answers are anything but simple—what the process of making concrete things reveals to us about ourselves. Learning from things requires us to care about the qualities of cloth or the right way to poach fish; fine cloth or food cooked well enables us to imagine larger categories of 'good'.
For its own sake
'Craftsmanship' may suggest a way of life that waned with the advent of industrial society—but this is misleading. Craftsmanship names an enduring, basic human impulse, the desire to do a job well for its own sake.
The details of construction
The housing developments in the Moscow suburbs were built mostly in the decades after the Second World War. Laid out as enormous chessboards, the suburbs stretch to the horizon across flat land sparsely planted with birch and aspen. The architectural design of the suburban buildings was good, but the state had not been able to command good-quality work. The signs of poorly motivated workers appeared in the details of construction.
The technology shelf
Motorola developed what it called a 'technology shelf', created by a small group of engineers, on which were placed possible technical solutions that other teams might use in the future; rather than trying to solve the problem outright, it developed tools whose immediate value was not clear.
The lure of inspiration
The lure of inspiration lies in part in the conviction that raw talent can take the place of training.
I don't think you understand
The physicist Victor Weisskopf once said to his MIT students who worked exclusively with computerized experiments:
When you show me that result, the computer understands the answer, but I don't think you understand the answer.
Impossibly coherent
...what gets lost mentally when screen work replaces physical drawing.
Drawing in bricks by hand, tedious though the process is, prompts the designer to think about their materiality, to engage with their solidity as against the blank, unmarked space on paper of a window.
Computer-assisted design impedes the designer in thinking about scale, as opposed to sheet size. The object on-screen can indeed be manipulated so that it is presented, for instance, from the vantage point of someone on the ground, but in this regard CAD is frequently misused: what appears on-screen is impossibly coherent, framed in a unified way that physical sight never is.
Head and hand
The blueprint signaled a decisive disconnection between head and hand in design: the idea of a thing made complete in conception before it is constructed.
Bodily reality
To do good work means to be curious about, to investigate, and to learn from ambiguity.
In the Fordist model of medicine, there must be a specific illness to treat, the evaluation of a doctor's performance will then be made by counting the time required to treat as many livers as possible and the number of livers that get well. Because bodily reality doesn't fit well inside this classifying model, and because good treatment has to admit experiment, a not insignificant number of doctors create paper fictions to buy themselves time from the bureaucratic monitors. Doctors in the NHS often assign a patient a disease in order to justify the time spent on exploring a puzzling body.
Awareness and knowledge
In the higher stages of skill, there is a constant interplay between tacit knowledge and self-conscious awareness, the tacit knowledge serving as an anchor, the explicit awareness serving as critique and corrective.
The journeyman
The apprentice goldsmith was place-bound while learning how to smelt, purify, and weigh precious metals. These skills required hands-on instruction from his master. Once the apprentice had locally presented his chef d'oeuvre, however, he could move from city to city as a journeyman, responding to opportunities. The traveling goldsmith journeyman made his presentation élevé to the corporate body of master craftsmen in foreign cities. Through his managerial talents and moral behavior he had to convince these strangers that he could become one of them. This migratory dynamism was built into medieval goldsmithing.
Sedentary guilds, by contrast, appeared to him insert and 'corrupt'. The good master, in his words, "presides over a traveling house."
Building generations
How did the builders of Salisbury Cathedral achieve this astonishing construction? There was no one single architect; the masons had no blueprints. Rather, the gestures with which the building began evolved in principles and were collectively managed over three generations. Each event in building practice became absorbed into the fabric of instructing and regulating the next generation.
A thousand little moves
Missing in these analyses is a reconstruction of the workshops of the master—more precisely, one element that has irretrievably gone missing. This is the absorption into tacit knowledge, unspoken and uncodified in words, that occurred there and became a matter of habit, the thousand little everyday moves that add up in sum to a practice.
The most significant fact we know about Stradivari's workshop was that he was all over it, popping up unexpectedly everywhere, gathering in and processing those thousand bits of information that could not signify in the same way to assistants who were doing just one part.
Mirror tools
A mirror-tool is an implement that invites us to think about ourselves. There are two kinds of mirror-tools. These are the replicant and the robot.
A quiet and contented mind
The Encyclopedia sought to get its readers out of themselves and into the lives of artisan craftsmen in order to clarify good work itself. Throughout, the volumes illustrate people engaged sometimes in dull, sometimes in dangerous, sometimes in complicated labor; the expression on all the faces tends to the same serenity. About these plates the historian Adriano Tilgher remarks on the "sense of peace and calm which flows from all well-regulated, disciplined work done with a quiet and contented mind."
The limits of language
The question of human limits was posed to Diderot the moment he, as it were, rose from his armchair. His method for finding out how people worked was, like a modern anthropologist, to ask them:
We addressed ourselves to the most skilled workers in Paris and the kingdom at large. We took the trouble to visit their workshops, to interrogate them, to write under dictation from them, to follow out their ideas, to define, to identify the terms peculiar to their profession.
The research soon ran into difficulty, because much of the knowledge craftsmen possess is tacit knowledge—people know how to do something but they cannot put what they know into words. Diderot remarked of his investigations: "Among a thousand one will be lucky to find a dozen who are capable of explaining the tools or machinery they use, and the things they produce with any clarity."
What we can say in words may be more limited than what we can do with things. Language is not an adequate 'mirror-tool' for the physical movements of the human body.
The wisdom of the apprentice
Diderot's solution to the limits of language was to become himself a worker.
Become an apprentice and produce bad results so as to be able to teach people how to produce good ones.
This is how I lived
Rather than convey "be like me," better parental advice should be more indirect: "This is how I lived" invites the child to reason about that example. Such advice omits "Therefore you should..." Find your own way; innovate rather than imitate.
Entropy
Imperfect, handmade glass has virtues: these are irregularity, distinctiveness, and what the writer refers to vaguely as 'character'. The two sets of images for glassblowing are thus inseparable; only by understanding how something might be done perfectly is it possible to sense this alternative, an object possessing specificity and character. The bubble or the uneven surface of a piece of glass can be prized, whereas the standard of perfection allows no room either for experiment or for variation.
Against the claim of perfection
We should not compete against the machine. Rather, against the claim of perfection we can assert our own individuality.
Seven lamps
Ruskin's Seven Lamps of Architecture provided seven guides, or 'lamps', for the troubled craftsman, guides for anyone who works directly on material things. These seven are:
- The lamp of sacrifice: The willingness to do something well for its own sake.
- The lamp of truth: The truth that 'breaks and rents continually'; Ruskin's embrace of difficulty, resistance, and ambiguity.
- The lamp of power: Tempered power, guided standards other than blind will.
- The lamp of beauty: Which for Ruskin is found more in the detail, the ornament—hand-sized beauty—than in the large design.
- The lamp of life: Life equating with struggle and energy, death with deadly perfection.
- The lamp of memory: The guidance provided by the time before machinery ruled.
- The lamp of obedience: Obedience to the example set by a master's practice rather than by his particular works; otherwise put, strive to be like Stradivari but do not seek to copy his particular violins.
I am here
I am here, in this work.
A maker's mark is a peculiar sign. Ancient brickwork established presence through small details marking 'it': the detail itself.
The great historian of bricks, Alex Clifton-Taylor, observes that what most counts about them is their small size, which just suits the human hand laying a brick. A brick wall, he says, "is therefore an aggregation of small effects. This implies a human and intimate quality not present to the same extent in stone architecture."
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.
Focal awareness
The philosopher Maurice Merleau-Ponty describes what she experienced as "being as a thing." The philosopher Michael Polanyi calls it "focal awareness" and recurs to the act of hammering a nail:
When we bring down the hammer we do not feel that its handle has struck our palm but that its head has struck the nail.
We have become the things on which we are working.
Sublime tools
Getting better at using tools comes to us, in part, when the tools challenge us, and this challenge often occurs just because the tools are not fit-for-purpose. In both creation and repair, the challenge can be met by adapting the form of a tool, or improvising with it as it is, using it in ways it was not meant for.
The all-purpose tool seems a special case. In its sheer variety, a flat-edged screwdriver admits all manner of unfathomed possibilities; it, too, can expand our skills if only our imagination rises to the occasion. Without hesitation, the flat-edged screwdriver can be described as sublime—the word sublime standing, as it does in philosophy and the arts, for the potently strange.
Crafting repair
Repair is a neglected, poorly understood, but all-important aspect of technical craftsmanship. The sociologist Douglas Harper believes that making and repairing form a single whole; he writes of those who do both that they possess the "knowledge that allows them to see beyond the elements of a technique to its overall purpose and coherence. This knowledge is the 'live intelligence, fallibly attuned to the actual circumstances' of life. It is the knowledge in which making and fixing are parts of a continuum."
Put simply, it is by fixing things that we often get to understand how they work.
When history moves on
Much twentieth-century urban planning proceeded on the principle: demolish all you can, grade it flat, and then build from scratch. The existing environment has been seen as standing in the way of the planner's will. This aggressive recipe has frequently proved disastrous, destroying many viable buildings as well as ways of life bedded into urban fabric. The replacements for these destroyed buildings have also, too often, proved worse: big projects suffer from overdetermined, fit-for-purpose form; when history moves on, as it always does, tightly defined buildings can soon become obsolete.
Details first
The identification a good craftsman produces is selective, that of finding the most forgiving element in a difficult situation. Often this element is smaller, and so seems less important, than the larger challenge. It is an error in technical as in artistic work to deal first with the big difficulties and then clean up the details; good work often proceeds in just the opposite fashion.
Walls and membranes
All living things contain two sites of resistance. These are cell walls and cell membranes. The cell wall is more purely exclusionary – a boundary; the membrane permits more fluid and solid exchange – a border.
Most pervasive in the modern city is the inert boundary established by highway traffic, cutting off parts of the city from each other. Working with resistance means, in urbanism, converting boundaries into borders.
The ground plane
Whereas Corbusier relegated streets to traffic functions, the ground plane represented to Van Eyck the realm in which people 'learn' cities. The placement of benches and bollards, the height of stepping-stones, the ill-defined separations of sand, grass, and water are all tools in that learning, an education in ambiguity.
Most cities were mostly built by improvisation
In Architecture Without Architects, Bernard Rudofsky documented the ways in which most cities were mostly built by improvisation, following no consistent formal design. Building was added to building, street to street, their forms adapting to different site conditions in the process of extension.
Rudofsky thought that this hidden order is how most settlements of poor people develop and that the work of improvising street order attaches people to their communities, whereas 'renewal' projects, which may provide a cleaner street, pretty houses, and large shops, give the inhabitants no way to mark their presence on the space.
The aspiration for quality
To arouse the aspiration for quality and make good on it, the organization itself has to be well crafted in form. It needs, like Nokia, open information networks; it has to be willing to wait, as Apple is, to bring its products to market until they are really good.
Oddity and peculiarity
The experienced doctor, as one would expect, is a more accurate diagnostician. This is due in large part to the fact that he or she tends to be more open to oddity and peculiarity in patients, whereas the medical student is more likely to be a formalist, working by the book, rather rigidly applying general rules to particular cases.
Relentlessness deformed it
I am not interested in erecting a building, but in presenting to myself the foundations of all possible buildings. — Ludwig Wittgenstein.
But in a note of 1940 to himself he wrote that the building "lacks health" or "primordial life".
In the construction of a house for his sister in the Kundmangasse, Wittgenstein's striving for an ideal perfection rendered the object lifeless. Relentlessness deformed it.
Necessity
Loos's need to respond positively to the difficulties he encountered appeared in the errors that occurred during the construction of the Villa Moller. When the foundations were not laid as specified, he could not afford to dig them up and start again; instead, Loos thickened the form of one side wall to accommodate the mistake, making the thickened wall and emphatic side frame for the front. The formally pure properties of Villa Moller were achieved by working with many similar mistakes and impediments Loos had to take as facts on the ground; necessity stimulated his sense of form. Wittgenstein, knowing no financial necessity, had no such creative dialogue between form and error.
The narrative of its making
Getting things in perfect shape can mean removing the traces, erasing the evidence, of a work in progress. Once this evidence is eliminated, the object appears pristine. Perfection of this cleaned-up sort is a static condition; the object does not hint at the narrative of its making.
The good craftsman
The good craftsman...
...understands the importance of the sketch—that is, not knowing quite what you are about when you begin.
...places positive value on contingency and constraint.
...needs to avoid pursuing a problem relentlessly to the point that is becomes perfectly self-contained.
...avoids perfectionism that can degrade into a self-conscious demonstration.
...learns when it is time to stop.Your life adds up
Weber's German word for a vocation, Beruf, contains two resonances: the gradual accumulation of knowledge and skills and the ever-stronger conviction that one was meant to do this one particular thing in one's life.
An English locution roughly conveys what he meant: your life 'adds up'.
To do just one thing well
The skills society is bulldozing the career path; jobs in the old sense of random movement now prevail; people are meant to deploy a portfolio of skills rather than nurture a single ability in the course of their working histories; this succession of projects or tasks erodes belief that one is meant to do just one thing well.
Manual labor
Artisanal craftsmen have proved particularly promising subjects for job retraining. The discipline required for good manual labor serves them, as does their focus on concrete problems rather than on the flux of process-based, human relations work. For this very reason it has proved easier to train a plumber to become a computer programmer than to train a salesperson; the plumber has craft habit and material focus, which serve retraining. Employers don't often see this opportunity because they equate manual routine with mindless labor.
Multiple choice
Intuitive leaps that open up a problem are impossible to test using multiple-choice questions. These leaps are an exercise of associating unlikely elements. There is no correct answer to the question "Are city streets like arteries and veins?"
Hephaestus
The clubfooted Hephaestus, proud of his work if not of himself, is the most dignified person we can become.
