Dual Symbolic Classification

Definition

Dual symbolic classification is the cross-cultural pattern — collected in Rodney Needham's Right and Left: Essays on Dual Symbolic Classification (1973) and going back to Durkheim & Mauss's Primitive Classification (1903) — by which societies organize the world into paired oppositions that load one pole with value and the other with its negation. The paradigmatic text is Robert Hertz's "The Pre-eminence of the Right Hand" (1909): "Society and the whole universe have a side which is sacred, noble and precious, and another which is profane and common; a male side, strong and active, and another, female, weak and passive; or, in two words, a right side and a left side." Hertz equated the right with rectitude, dexterity, "the juridical norm," life, the inside, the sacred, good and beauty; the left with the profane, the ugly, bad, death, "the outside, the infinite, hostile and the perpetual menace of evil" — concluding, from the myth of Eve formed from Adam's left rib, that "one and the same essence characterises woman and the left side of the body." Ardener's contribution is to add the spatial-oppositional pairs most relevant to interior theory — public/private and inside/outside (the latter "a particular concern of modern Greeks, as shown by Hirschon") — to the received list: "male and female, east and west, future and past, top and bottom, right and left" (Bourdieu, quoted p. 19). Examples abound in her chapter: the Mapuche "inferior-superior, left-right hand associations" with "an unmistakable and literal connection between left and evil, right and good" (Faron); coloured space among the Zuni, Atoni and Irish.

Key Thinkers

• Robert Hertz — "The Pre-eminence of the Right Hand" (1909; Needham's translation 1973): the right/left template and its gendered naturalization; not yet paged (see log).
• Shirley Ardener — extends the oppositional list to public/private and inside/outside, linking classification to women's spatial condition.
• Rodney Needham — editor of Right and Left (1973), the comparative collection; not yet paged (see log).
• Durkheim & Mauss — Primitive Classification (1903): "Cosmic space and tribal space are thus only very imperfectly distinguished"; not yet paged (see log).
• Pierre Bourdieu — the schemes of perception that "divide the world up" in oppositions (Outline of a Theory of Practice, p. 15, quoted in Ardener); the classification apparatus as the background of the habitus.
• Ferdinand de Saussure — the structural-linguistic ground: meaning as differential, the value of terms defined by what they are not.

Related Concepts

• Structuralism — the oppositional logic classification shares with Saussurean linguistics and Lévi-Strauss's analyses.
• Gendered Space — the male/female opposition materialised as spatial order.
• Partition of Space — classification as the cognitive machinery of spatial partitioning.
• Habitus — Bourdieu's schemes of perception as the embodied, practical form these classifications take.
• Semiotics — the sign-theoretic reading: opposition as the generator of meaning.
• Separate Spheres — the public/private pair as institutionalised classification: the nineteenth-century interior.
• Transpatial Solidarity — the spatial-logical heir of the oppositional mode: interiors affiliated "by virtue of analogy and difference" — the classification principle recast as a theory of how bounded spaces form systems (Hillier & Hanson).

Source Support

Sources in the wiki that discuss this concept:

• The Partition of Space (Ardener 2006) — Hertz's right/left universe (p. 19); the added public/private and inside/outside pairs and Hirschon's Greeks (p. 19); the Mapuche and Amboyna cases (p. 19); coloured space (p. 18); Needham, Durkheim & Mauss and Bourdieu in the apparatus (pp. 19–20).
• Buildings and their Genotypes (Hillier & Hanson 1984/2006) — the inside/outside pair as a generative opposition rather than a classificatory one: the duality of inside and outside is "the fundamental fact of the boundary" — the inside affiliated by analogy and difference (a transpatial system), the outside by continuity and proximity — so the pair does not just classify but produces two different systems of social relation (transpatial-solidarity). Where Ardener adds inside/outside to the classification pairs, Hillier and Hanson give the pair its mechanism: the boundary that "creates a category of space – the interior – and a form of control" at once (pp. 150–151).
• Ornament and Order (Soulillou 2002/2006) — the classification apparatus given its ornamental register, the ground plan: "The appearance of order in ornament is produced according to what I would call a ground plan (or original matrix), traversed by a double polarization: transversal in one respect, as in the male/female opposition, and vertical in another, as in the superior/inferior opposition" (p. 315) — "sexuality and power are the forces which sustain the ground plan," and "order initially appears through that feature of the ground plan where the sexual relation is intersected by the power relation" (p. 315). The traditional scheme realizes the pairs in ornament directly: "from left to right, without hierarchy, ornaments for men, ornaments for women; from upper to lower, with hierarchy, ornaments for the prince, the nobles, free men in general, and the slaves" (p. 316) — the right/left pair (transversal, unordered) and top/bottom pair (vertical, hierarchized) of the classification apparatus, encoded not in cognitive schemes but in who wears what. The concept's strongest extension: classification as material practice on bodies — the ornament that "appropriates the individual with the purpose of assigning a place in a social or cosmic order" (p. 316). See ornamental-ground-plan, gendered-space.

Open Questions

• Hertz's catalogue assigns 'inside' to the right/sacred/male pole and 'outside' to the left/profane/female pole — does the interior discipline inherit a classification whose deep grammar codes the inside as masculine despite its cultural coding as feminine (cf. separate-spheres)?
• Ardener warns the field "requir[es] delicate handling — especially of the relationship between concepts placed in vertical lists." Are the design disciplines' own paired valuations (structure/ornament, form/function) dual classifications in Hertz's sense — and what would it mean to un-pair them?
• The oppositions are presented as culture-specific yet universally recurrent: is the recurrence cognitive (a human classification instinct), social (a mechanism of dominance), or both — and does the answer change how designers should treat binary programming of space?
• Soulillou's ground plan shows classification operating materially — ornament assigning bodies their place on the right/left and upper/lower axes ("the ornament that appropriates the individual," p. 316) rather than merely coding perception. Is the wiki's classification apparatus then primarily cognitive (Bourdieu's schemes) or materially enacted (ornament, dress, room-codes), and does the ornamental register change the design implication (you could redesign the schemes, or you could redesign the ornaments)?
• Soulillou's transversal axis is explicitly without hierarchy ("ornaments for men, ornaments for women") while his vertical axis is hierarchized — a refinement Hertz's catalogue lacks. Are the classification pairs differentiated by type (some oppositions rank, some only differentiate), and does the wiki's separate-spheres material (public/private as a ranking pair) belong to the second class?
