The first half visualises Foucault's architecture — the gaze of Las Meninas, the three epistemes side by side, the great ruptures, and a map of his key terms. Below that, a single card for every chapter, faithful to the text and colour-coded by the era it describes.
Foucault opens the book with Velázquez's 1656 canvas. Every gaze in it converges on one point outside the frame — the place of the king and queen being painted, of the painter, and of us, the viewers, all at once. That point can never appear in the picture. The painting stages the whole cycle of Classical representation and, at its heart, an essential void.
Velázquez steps back from a canvas turned away from us — visible only because he has paused. We never see what he paints.
It reflects not the room but what stands outside the picture: King Philip IV and Queen Mariana — the sovereign subject that structures everything yet cannot appear within.
Neither entering nor leaving, a "pendulum" between inside and outside — echoing the mirror's oscillation.
Model, painter and spectator occupy one exterior place that the image structurally cannot show. "What we see never resides in what we say."
Each age organises language, life and wealth on the same hidden ground. Read each row across to see how one underlying principle reshapes all three empirical domains at once — and how the names of the sciences themselves change as the ground shifts.
Foucault's "archaeology" is not the history of ideas accumulating. Knowledge does not improve gradually; it is reorganised abruptly. Two great silent breaks divide Western thought — and each happens simultaneously across language, life and wealth.
In the Renaissance, to know was to interpret. The whole world was a web of correspondences held together by four kinds of resemblance — and every resemblance had to be marked by a visible signature to be read at all.
Things that touch resemble each other — neighbours sharing edges and properties.
Resemblance across space, like reflection — the face mirrors the sky.
Likeness of relationships, with man as the great fulcrum: veins as rivers, flesh as soil.
The free-ranging pull (and counter-push) that balances the world and underlies the other three.
The deepest event of the mid-17th-century break is a quiet reorganisation of the sign. When resemblance ceased to bind the mark to the thing, the sign collapsed from three terms into two — and lodged itself entirely inside representation.
A third element — resemblance — is needed to fasten the mark to what it marks. The sign is part of the world, not a tool laid over it. To interpret is to read nature's text.
Port-Royal's formula: one idea simply represents another. But the sign also doubles back to represent its own power to represent — so signification and meaning become co-extensive.
Foucault's argument turns on a small set of interlocking concepts. This map shows how they connect: the episteme grounds representation, which in the Classical age becomes the table, whose collapse opens the depths that make "man" and the human sciences possible.
"Man" is not eternal. He appears only when the Classical table collapses and knowledge acquires depth. Foucault diagnoses four unstable folds that constitute this recent figure — the "anthropological quadrilateral" — and argues the same gesture that invented man may now erase him.
Man knows himself only through the very limits — life, labour, language — that exceed and precede him. He is finite, and that finitude grounds his knowledge.
Man is at once an object in the world to be studied and the subject that makes all knowing possible — an unstable oscillation (Comte and Marx as twin instances).
Thought is forever haunted by what it cannot think — the unconscious, the unsaid. The unthought is man's contemporaneous "twin," not a buried interior.
Man can never reach his own beginning; things are always older than he is. His origin recedes as he approaches it — hence the modern obsession with return.
Every part of the book, summarised faithfully. The coloured left edge marks which episteme the chapter chiefly excavates — Renaissance, Classical, Modern, or method & thresholds.
Opening · Method and the museum-pieceFoucault opens with the laughter — and unease — provoked by Borges's fictitious "Chinese encyclopaedia," whose animal categories are so incoherent that no shared space could contain them. What is monstrous is not the strange contents but the destruction of the common table on which things could even be compared. From this he introduces his central concern: every culture rests on a hidden ground of order — an episteme — that makes classification and knowledge possible. His method is "archaeology," not the history of ideas: it uncovers the historical conditions of possibility for knowledge, and reveals two great discontinuities, after which "man" appears for the first time.
A dense reading of Velázquez's 1656 painting as the emblem of Classical representation. Foucault dissects its network of gazes: the painter looks out at an unseen model; the Infanta and her entourage fill the foreground; and a mirror on the back wall reflects the faint forms of King Philip IV and Queen Mariana — the sovereign subject who is at once the painting's reason and its most ghostly absence. Painter, mirror and the man in the doorway are three projections of a single exterior point — the place of model, spectator and author together — which is structurally invisible within the image. The painting represents representation itself, and at its centre lies an essential void.
The Renaissance episteme, in which resemblance organised all knowledge. Four similitudes — convenientia, aemulatio, analogy, and sympathy/antipathy — wove the world into a vast web of correspondences. Because resemblances are hidden, they require visible signatures to be read: the world's face is covered in marks, and knowledge means deciphering this text. Language itself partook of the order — words were things, the universe a book. At the Renaissance's close, language separated from the world, the ternary sign became binary, and the age of representation began — its lost "raw being of language" surfacing thereafter only in literature.
Don Quixote is the hinge between resemblance and representation — "the hero of the Same," a man made of language whose quest for similitudes the world no longer confirms; Foucault calls the novel "the first modern work of literature." The Classical age then substitutes Order for resemblance. Descartes purifies comparison into measurement and order; the sign becomes binary (Port-Royal); resemblance is demoted to the pre-analytic raw material of knowledge. The episteme rests on three interlocking structures — mathesis (universal science of order, via algebra), taxinomia (the table of identities and differences, via signs), and genesis (how ordered representations arise). "The centre of knowledge… is the table."
The Classical theory of language. Words are not opaque objects to be interpreted but a transparent function of representation: language unfolds simultaneous thought part by part, in linear succession. Foucault works through four pillars — the proposition (and the verb "to be"), articulation (nouns), designation (the bodily origin of language), and derivation (rhetorical figures) — synthesising them as a "quadrilateral" whose centre is the Name. Classical discourse always tends toward nomination. With Sade the name is finally uttered for its own sake, language becomes brute being, and the framework collapses into what the 19th century calls Literature.
Classical natural history was not a precursor to biology but a wholly different knowledge, organised around the visible surface of things and their naming in language. Its central scandal: "life itself did not exist" — only living beings arranged in a taxonomic grid. Description proceeds through four variables (form, number, proportion, situation) summed up as structure, leading to classification by character. The "System" (Linnaeus: pick a few privileged features) and the "Method" (Buffon, Adanson: total resemblances) rest on the same base. The so-called evolutionisms of the period are not Darwinian; they use time to traverse a pre-set table, not to generate new forms.
The Classical "analysis of wealth," governed by the same logic of representation. Political economy did not yet exist; what existed was a coherent domain of wealth. Foucault rehabilitates mercantilism: money became the instrument of representation for wealth — "gold is precious because it is money, not the reverse." Money is defined as a pledge; Cantillon introduces time and cyclical dynamics. Physiocrats and utilitarians traverse the same theoretical segment in opposite directions — one beginning from nature's surplus, the other from subjective need. All three Classical sciences rest on one condition: the sovereignty of representation. Sade closes the age as Don Quixote opened it.
The epistemic rupture of roughly 1775–1825, when the ordered table was displaced by History, depth and organic structure. In three parallel domains a non-representable element erupts: labour (Adam Smith), organic structure (Jussieu, Lamarck), and inflectional systems (Jones, Coeurdoux). In each case explanation now runs from the visible surface down to a hidden depth and back — "to relate the visible to the invisible." The philosophical counterparts are Ideology (Destutt de Tracy — the last Classical philosophy) and Kant's Critique, which for the first time questions the very limits of representation and "marks the threshold of our modernity."
How the three new "quasi-transcendentals" reground knowledge. Production replaces exchange in economics (Ricardo); function and organic structure replace visible characters in biology (Cuvier); internal grammatical law replaces representational value in language (Bopp, Grimm, Schlegel). Knowledge acquires depth and historicity. This constitutes a homo oeconomicus defined by finitude and the threat of death; the privileged emblem of life shifts from the transparent plant to the hidden, drive-ridden animal. Language is demoted to an object — compensated by literature, exegesis, formalization, and the discovery of the unconscious. Nietzsche burns the whole arrangement from within.
The emergence of "Man" as an object of knowledge — a recent invention not two centuries old. Before the end of the 18th century, man did not exist epistemologically: Classical knowledge had human nature and general grammar but no science of man, because discourse — not man — held the sovereign place (the king's empty position in Las Meninas). Modern thought constitutes man through four folds: the analytic of finitude, the empirico-transcendental doublet, the cogito and the unthought, and the retreat and return of the origin. The "anthropological sleep" mistakes this self-grounding circle for rigour; Nietzsche breaks it, joining the death of God to the end of Man.
The human sciences did not inherit a domain — they emerged only when "man" was constituted as both empirical object and epistemological subject. They occupy an unstable "hypo-epistemological" position, duplicating the sciences (biology, economics, philology) that frame them. Their positivity is organised around three pairs of models — function/norm, conflict/rule, signification/system — and a historical drift from the first term of each toward the second (Freud the pivot). History both constitutes and undermines them. Psychoanalysis and ethnology are "counter-sciences" that do not ground man but dissolve him — pointing, with linguistics, toward the "death of man" that closes the book.
