The presidential address to the Mathematical Association of England, on inert ideas and the aims of a general education.
41 passages192936 min6 chapters
Where meaning outranks mechanism: depth psychology reading the symbol, and the holy read on its own terms.
C. G. Jung
The book that broke with Freud — libido read as symbol rather than drive, argued across myth, scripture and poetry — in Beatrice M. Hinkle’s translation, with its full apparatus of notes.
1210 passages1916
C. G. Jung
Fifteen papers, from the 1902 dissertation on the occult to the essay that first names the collective unconscious — analytical psychology arriving in English under its own name.
1255 passages1917
Rudolf Otto
Otto’s inquiry into the numinous — the encounter with the holy before any doctrine has words for it — in John W. Harvey’s translation.
282 passages1923
The claim that how a thing is made is a moral statement. Ruskin makes it; Morris takes it to the workshop.
John Ruskin
The chapter Morris called one of the very few necessary utterances of the century — the moral case against the division of labor, argued from the stones of a cathedral.
194 passages1853
William Morris
Five lectures, 1878–1881, opening with 'The Lesser Arts' — the founding sermon of the design profession: art, labor, and the dignity of useful work.
496 passages1882
Public argument at full strength: theses, open letters, and the machinery of persuasion, four centuries apart.
Martin Luther
The Ninety-Five Theses — the disputation notice that became a broadside and set the pamphlet economy in motion. Read here as a designed object: format as strategy.
97 passages1915
Martin Luther
The cheap German quarto aimed past the hierarchy at the reader — Luther's first constructive Reformation program, with all 271 of the Holman edition's notes anchored inline.
205 passages1915
Edward L. Bernays
The ad age's founding confession — the conscious and intelligent manipulation of the organized habits and opinions of the masses, explained cheerfully as a profession, by Freud's nephew.
448 passages1928
Bertrand Russell
The lecture to the National Secular Society, March 1927 — the secular case stated plainly, set opposite Chesterton's Orthodoxy in the course's central debate.

A walk through the library with the reason for each step written down.
Start here The symbol and the sacred. Every step opens, it begins with a book, and each picture in it is joined to its passage by an editor.
Liu An
Two stories from the Huainanzi argue one claim: fortune and misfortune turn into each other. A family in Song is saved from a massacre by its blindness, and a frontier family's runaway horse costs the son a leg and spares him a war.
12 passages
A picture is here because of a passage. Where an editor has read one against the other, the picture stands in its subject beside every hand that took the same subject; the rest of the holding is shelved by era and by collection until a subject is found. Everything is public domain by the holding institution's own account, from Cooper Hewitt, Smithsonian Design Museum (9965), The Art Institute of Chicago (849), Metropolitan Museum of Art, New York, NY (772), Cleveland Museum of Art (648) and 43 more collections.

Wooded landscape with the sacrifice of Isaac (Genesis 22)Abraham Govaerts1607
The Netherlandish landscape tradition takes Genesis 22 as its nominal subject and then gives almost the whole panel to trees and weather. Where the sacrifice sits in the picture — small, far off, easy to miss — is itself a reading of it.

Work the library points at rather than owns. Open collections release almost nothing published after 1930, and most of what design argues about came after, so these rows carry the record and the link and leave the copy where it belongs.
Where it was conducted, issue by issue, in public. Held by their publishers, not by us.
Twenty four years of spreads that treated the page turn as the unit. The origin of modern art direction.
Held by MoMA
First woman admitted to the Art Directors Club. She commissioned fine artists to illustrate magazines aimed at teenage girls, which was an argument about who deserves serious work.
Held by Cooper Hewitt and the Pineles estate
Covers built on one idea, executed photographically.
Held by Cooper Hewitt
A twelve column grid used with almost violent scale contrast. Still the most copied magazine nobody has read.
Held by Die Neue Sammlung
Co-directed Bazaar at 26. Pairs with Brodovitch to show what changed and what did not.
Held by Cooper Hewitt
A weekly paper as an organizing tool. The clearest case in the course of design doing political work with no budget.
Held by MoMA and the Oakland Museum
The opposite pole from Tufte: illustration used to make a number stick. Teach them together and let the class fight.
Held by Nigel Holmes and Print archive
Brody built a new masthead almost every issue, which made the magazine identity an ongoing act rather than a fixed mark.
Held by the V&A, which collects his work
The magazine where the typography carried the editorial position instead of serving it. Licko drew the faces, VanderLans set the pages, and the two jobs stopped being separate. Back issues are sold by Emigre directly.
Held by Emigre Inc.
An entire issue as one digital image, made when that was barely possible.
Held by Design Quarterly and Walker Art Center
The essay that named the absence. Assign it alongside the canon, not after it.
Held by Print Magazine archive
Where design criticism actually happens. Useful for teaching students to write about work, not just make it.
Held by Eye Magazine
A Benetton-funded magazine that spent the budget on race, AIDS, and war. Good for the ethics unit: who paid, and what did they get.
Held by Benetton Group, which published it
Typefaces published as experiments, four to an issue with a poster each. Nobody was expected to set text in them.
Held by Taschen (collected edition)
The test case for whether legibility is the same thing as communication. Carson set an interview in a symbol font. Useful in class precisely because students disagree about it.
Held by Ray Gun Publishing and private collections
Marks, programs and the manuals that made them repeatable. The deliverable is the system, not the logo.
One of the first Black designers to lead a network design group. The 1963 stamp is his.
Held by Smithsonian
The case that a mark is the smallest part of an identity. The program, not the logo, is the deliverable.
Held by IBM
Decades of marks from one office, which lets students compare a house method against changing fashion.
Held by Chermayeff and Geismar and Haviv
Ulm method applied in Sao Paulo. Good for asking what travels and what does not.
Held by Museu da Casa Brasileira and Lars Muller
Shows Rand solving the same problem twice in different registers, which makes the reasoning visible.
Held by IBM and AIGA Design Archives
Swiss training turned loose on architecture at full wall scale.
Held by SFMOMA
Survived almost fifty years untouched, which is what restraint buys.
Held by Vignelli Center for Design Studies
Op art, Huichol pattern and the Games logotype fused into one system that ran the whole city.
Held by Cooper Hewitt
The same designer working at the opposite end of the scale from titles.
Held by AIGA Design Archives
The clearest fight in the course: a diagram that is right about the network and wrong about the city. It was replaced in 1979.
Held by MoMA
Pictograms built on one grid, so an entire wayfinding language stays consistent. The origin of most airport symbols in use now.
Held by Die Neue Sammlung, The Design Museum Munich
A mark that escaped its owner. Good for the unit on ownership and trademark.
Held by New York State and MoMA
A city dressed on a budget with colour and scaffolding. The counter-argument to Munich rigor.
Held by Getty Research Institute
A partner model where the designer stays the author. Relevant to the business half of the course.
Held by Pentagram
Typography doing the work of illustration. A system loose enough to keep generating new work.
Held by Pentagram
Public information design at national scale, judged by whether people actually responded.
Held by AIGA and the Sylvia Harris estate
Emptiness argued as a brand position. Pairs against maximalist identity work.
Held by Nippon Design Center and Lars Muller
Swiss practice written down by the people who ran it, and still in print.
A book that tells a story with geometry alone. Useful against the assumption that narrative requires pictures.
Held by MoMA
Statistics as repeatable pictograms, built so an unschooled reader could check the claim. The origin of the whole pictogram tradition.
Held by University of Reading Otto and Marie Neurath Collection; published by Hyphen Press
The only woman to run a Bauhaus workshop. Worth naming when the school is taught as a list of men.
Held by Bauhaus-Archiv
The manifesto, then his own later retreat from it. Teach both halves.
Held by University of California Press (translation in print)
Technical information made genuinely clear, decades before anyone called it information design.
Held by Stedelijk Museum
Covers that interpret rather than illustrate. Good for the brief on abstraction.
Held by AIGA Design Archives
Still the shortest good statement of why a designer should be able to explain a choice.
Held by Chronicle Books (in print)
Where information design becomes a discipline with rules. Parentheses around area codes are his.
Held by Cooper Hewitt
Took over the studio after Alvin Lustig died and became a stronger designer than the reputation allows. Good for talking about attribution and whose name survives.
Held by Cooper Hewitt
Design as a rule set that generates outcomes. The direct ancestor of design systems, and worth saying so in class.
Held by Lars Muller (in print)
Two versions, 1964 and 2000. Reading them together shows what the profession did and did not learn.
Held by Eye Magazine
Basel teaching written down: contrast, scale, and figure and ground as exercises.
Held by Niggli (in print)
The Bauhaus sent women to the weaving workshop. She made it the most rigorous department in the building.
Held by Josef and Anni Albers Foundation; published by Princeton University Press
A national rail network reduced to one symbol and one typeface, specified to the millimetre.
Held by Standards Manual
Short pieces that make method feel like play without making it trivial.
Held by Penguin and Phaidon
The counterweight to Tschichold. Method over manifesto.
Held by Niggli (in print)
A whole system written down. Pairs with the brand book unit.
Held by Standards Manual
Opens by calling industrial design a harmful profession. Assign it early so the ethics unit is not an afterthought.
Held by Thames and Hudson
Ran MIT Press design, then built the lab where typography met the screen. The direct ancestor of everything interface typography does now.
Held by MIT Museum and Cooper Hewitt
The worm, and the system around it. Shows an identity manual as a legal and operational document.
Held by Standards Manual
The book the studio unit is built on. Explains the grid as a way of deciding, not a way of decorating.
Held by Niggli (in print)
Argues that chart junk is a moral failure, not a taste failure. Students argue back, which is the point.
Held by Graphics Press
The first widely read argument that consistency across applications is a design responsibility, not a limitation.
Held by Apple
Affordance and feedback, explained with doors. The book that made usability legible to non-designers.
Held by Basic Books
Historical lettering used precisely rather than nostalgically.
Held by Louise Fili Ltd and AIGA
The reference students actually keep. Opinionated in a way a manual usually is not.
Held by Hartley and Marks
The book that took Ray Gun off the newsstand and onto every design student's shelf.
Held by Chronicle Books
Books where the physical object carries the argument. Pairs with the printing history the library owns outright.
Held by Irma Boom Office and Lars Muller
The best first typography book, and it takes the reader seriously.
Held by Princeton Architectural Press
Interviews with the people who built the field. Names interaction design as a discipline with a history.
Held by MIT Press
A working designer explaining decisions in plain language. Good writing model for the studio reports.
Held by Princeton Architectural Press
Faces drawn to say something about what reading is for.
A single alphabet with no capitals, drawn from the circle and the line.
Held by Bauhaus-Archiv Berlin
Calligraphic judgment carried into metal, then photo, then digital.
Held by Klingspor Museum and Letterform Archive
A family planned as a grid of weights and widths before any of it was drawn.
Held by Die Neue Sammlung
A face shaped by what a CRT could actually render. Deliberately close to unreadable, and Crouwel published it anyway.
Held by Stedelijk Museum
Faces drawn for hostile conditions: thin phone paper, then bad screens. Constraint stated as the brief.
Held by MoMA
Pixel by pixel, the first interface most people ever trusted. Constraint as the whole design brief.
Held by MoMA
Faces drawn for the screen resolution of the moment, then defended as legitimate rather than apologized for. Mrs Eaves later showed the same designer working entirely inside history.
Held by Emigre Inc.
Designed for a specific client problem, then general. The commissioning unit.
Held by FontFont and Monotype; sold via MyFonts
A revival that is openly an interpretation. Good for the authenticity discussion.
Held by Emigre Inc.
Drawn from New York lettering, then used everywhere. Shows a face acquiring meaning through use.
Held by Frere-Jones Type
The work itself, where it can still be seen.
Photomontage as public speech. The persuasion unit.
Held by Pushkin Museum and MoMA
Photomontage and scale contrast used commercially, years before the Swiss school formalized it.
Held by MoMA
Modernist form aimed at an audience that had never seen it. Pairs with the WPA posters the library owns outright.
Held by MoMA
Painted, handmade posters made under a state monopoly. Shows constraint producing a school rather than a style.
Held by Museum of Modern Art and Polish poster collections
Illustration, historical pastiche, and warmth, in the same years Swiss neutrality was winning.
Held by Push Pin and AIGA Design Archives
Titles that set up the film rather than label it. The clearest example of design carrying narrative.
Held by Academy Film Archive
Music rendered as geometry. Shows a method holding up across a long series. The Zurich collection is searchable rather than addressable, so the link opens eMuseum and the series is found from there.
Held by Museum fur Gestaltung Zurich
Type, one photograph, two colours, several hundred times. The best argument in the course for a system that stays interesting.
Held by Blue Note and MoMA
Photography and the flag reduced to geometry. The first Olympic identity that worked as a system.
Held by MoMA
Posters folded into a magazine and mailed worldwide. Distribution as part of the design problem.
Held by Library of Congress and MoMA
Advertising that made the industry look at its own racism. Confrontational on purpose.
Held by AIGA Design Archives
Design taught as a political question. Useful when students assume neutrality is available.
Held by Getty Research Institute
A designer who worked anonymously and quoted modernism as a joke.
Held by Victoria and Albert Museum
Sleeves that refused to name the band. Worth arguing about whether that is confidence or contempt.
Held by Design Museum
A Noh face built from flat rectangles. Swiss method and Japanese tradition without either giving way.
Held by MoMA
Atmosphere as the brief. Nearly unreadable and completely coherent.
Held by Victoria and Albert Museum
Deliberate error as a method. The strongest test of whether students can separate taste from judgement.
Held by Letterform Archive
Modernism practised deliberately and self consciously after everyone declared it over.
Held by Roma Publications and Eye
Useful for the ethics discussion about what a designer owes the audience and themselves.
Held by Sagmeister and Walsh
A documentary students actually finish. Everyone from Vignelli to Sagmeister on one typeface, agreeing about nothing.
Held by Hustwit
Paintings, prints, buildings, floors and music built on the mathematical objects in Shapes. Most are in copyright or are not files at all.
Thirteenth-century marble floors where a triangle is filled with smaller triangles at least three levels deep. The resemblance to the Sierpinski triangle is a modern reading of the pattern; nothing records it as the masons’ intent.
Held by Cattedrale di Santa Maria, Anagni
An inlay in the basilica floor showing the small stellated dodecahedron, often dated about 1430, two centuries before Kepler described the solid. The attribution to Uccello is repeated widely and documented thinly.
Held by Basilica di San Marco, Venice
Pacioli demonstrates Euclid at a table while a glass rhombicuboctahedron, half full of water, hangs beside him. The attribution and the sitter beside him are both disputed.
Held by Museo di Capodimonte, Naples
The first hyperboloid tower, a water tower made entirely of straight steel members. Two families of straight beams lean against each other and make a curved lattice.
Held by Polibino, Lipetsk Oblast
Cherrywood and string. Moore named the string models in the Science Museum, London, as the source: straight threads strung between two frames to make a curved surface you can see through.
Held by Hirshhorn Museum and Sculpture Garden, Smithsonian Institution
Painted from Man Ray’s 1934 photograph of a plaster model at the Institut Henri Poincaré, a Kummer surface with eight real double points. He named it for the drips that ran down the canvas like tears.
Held by Hirshhorn Museum and Sculpture Garden, Smithsonian Institution
Two tetrahedra pierce each other as a stella octangula. One is built over with houses and roads, the other is wild, and Escher wrote that they fit together without knowing about each other.
Held by National Gallery of Art, Washington
A small stellated dodecahedron with a creature caught in each of its twelve star points, neck and legs pushed out through the openings.
Held by M.C. Escher Foundation, shown at Escher in Het Paleis, The Hague
Christ hangs before a cross made of eight cubes: the net of a tesseract, the four-dimensional cube unfolded into our space the way a cube unfolds into six squares.
Held by The Metropolitan Museum of Art
For 61 players, first heard at Donaueschingen in 1955. Each string glissando is a straight line on Xenakis’s pitch and time graph, and together the lines sweep curved surfaces, which he later built in concrete.
Held by Boosey & Hawkes
The supper takes place inside a vast transparent dodecahedron. Dalí tied its twelve pentagonal faces to the twelve apostles, and the gallery reads the enclosure as the room of the scene.
Held by National Gallery of Art, Washington
A tent of hyperbolic paraboloid shells. Xenakis said he had built the ideas of Metastaseis in it: the straight lines of the glissandi became the straight lines of the shells.
Held by Demolished in 1959
Ants walk the band in single file. Each one passes over both faces of the strip and comes back to its start, because the strip has only one face.
Held by National Gallery of Art, Washington
A geodesic sphere of steel tubes 76 metres across, the best known of Fuller’s domes.
Held by Parc Jean-Drapeau, Montreal
Each section of the novel opens with a further iteration of the dragon curve, under Ian Malcolm’s lines about how a system turns unpredictable.
Held by Alfred A. Knopf
A steel model of Boy’s surface, installed outside the institute on 28 January 1991. Its strips follow a polar grid under the parametrization of Robert Bryant and Rob Kusner.
Held by Mathematisches Forschungsinstitut Oberwolfach
One of a series of glass Klein bottles blown for the Science Museum. Some in the series are cut open to show the two Möbius bands a Klein bottle is made of.
Held by Science Museum Group, London
A pop song about the set, from the album Where Tradition Meets Tomorrow. It names the Sierpinski gasket on the way.
Held by Jonathan Coulton
Scripture
The Douay-Rheims American Edition of 1899 — Challoner’s revision of the translation made at Reims and Douai from the Latin Vulgate, and the English Catholic Bible that was in print before the King James. Seventy-three books in the order the Vulgate puts them, under the names the translation itself uses, including the seven the Protestant canon sets apart. Every verse is a block, and every citation is an address.

This course is about illustration as a means of communicating ideas. Concepts and sketches come first, on paper. The computer, industry standard software on the lab machines, is the tool that finishes the piece, not the place the idea starts. The semester covers three toolsets in order: vector, raster, and motion. Four projects put them to work: an editorial hero with its spots, an illustrated poster drawn by hand and finished digitally, a packaging illustration, and an animated loop. Class time splits between taught workshops and worked studio time, and every project ends in a critique. Every project is marked on the same four things: participation and process, concept, formal resolution, and craft.
AI is changing how design gets made, and the profession is still working out what the medium is. This course takes both halves seriously. You learn design practice and process the way the discipline has always taught it: research, iteration, critique, craft. And you learn to make work with AI the way working studios use it now, on real production, with your name on the output. You carry one project across the whole semester. It starts the way a startup starts: with a real product or technology that has no market yet. You research who could want it, choose an audience, pitch your creative strategy to the room in September, and set the brand's direction out of the October explorations. Then you build the brand, write it down as rules a machine can follow, and use it to make the product's case: a brand book with the product-market fit plan inside it, and a landing page for signup. Along the way we read the people who built the discipline and look at how the best teams and brands are working right now. The field is being redrawn while you are entering it, and you should have a hand in it.
The works the project is built on, and the seed of the shop. Each record names the edition worth owning and where to get it: a book is only listed where the library already engages with it.
