Summary

Andreotti reads the Situationist International's urban practices of 1957–1972 through the lens of Johan Huizinga's theory of play (Homo Ludens), a source whose role he argues is neglected in recent historiography. He traces how the three key protagonists around the group's founding — Debord, Giuseppe (Pinot) Gallizio, and Constant — each radicalized Huizinga's ludic philosophy into a revolutionary ethics that abolished the distinction between play and seriousness, and between art and everyday life. Concentrating on the dérive, détournement, Gallizio's "Industrial Paintings"/Cavern of Anti-Matter, and Constant's New Babylon, he proposes play as a bridge between the SI's "first" and "second" phases and stresses the agonistic drive of the avant-garde.

Key Claims

• The palindrome Girum Inus Nocte et Consumimur Igni ("we go round and round in the night and are consumed by fire") serves as a figure for the SI's urban play-tactics, recalling Huizinga's account of play as cutting "clean across any possible distinction between play and seriousness."
• The dérive is an active "mode of experimental behavior," an art of urban wandering (distinct from Dada/Surrealist excursions), whose moments are captured in Debord & Jorn's Mémoires and Debord's psychogeographies (e.g. The Naked City, Discours sur les Passions de l'Amour).
• Hubert/gallizio's Industrial Paintings and the Cavern of Anti-Matter sought to "devalue" art, reimmersing it in the everyday (against Huizinga's "over-valuation" of art), attacking professionalism and the institution of the art gallery.
• Constant's New Babylon is the most complete attempt to give architectural form to a situationist city: sectors of movable prefabricated elements organized around the "principle of disorientation," abolishing functional zoning and public/private separation, for a "New Babylonian" citizenry liberated from work and the family to devote themselves to the dérive and play.
• New Babylon's debt to Team X's Berlin proposal and to Henri Lefebvre's "tissue urban" is noted, along with the anticipation of Cedric Price's Fun Palace; it was subject to criticism that it would be "recuperated" into mere compensation for society's shortcomings, and assimilated into 1970s-80s commercial speculation.
• The "second phase" of the SI (after Constant's 1960 resignation) extended play-tactics into highly politicized behavior — graffiti, barricades, détournement of streets in May '68.
• The agonistic drive: the palindrome recalls Poggioli's description of the avant-garde's self-immolation, "an obscure sacrifice to the success of future movements."

"We crave adventure. Not finding it on earth, some have gone seeking it in the moon. We prefer to wager first on a change on earth. We propose creating situations there; new situations." (quoting Constant, 'Another City for Another Life')

"All revolutions enter history and history rejects none of them; and the rivers of revolution go back to where they originated, in order to flow once again." (quoting Debord)

"an obscure sacrifice to the success of future movements." (on the agonistic drive, after Poggioli)

Open Questions

• Does the play emphasis resolve the standard split in SI historiography between the "first" (artistic/urbanistic) and "second" (political) phases, or does it risk romanticizing the group's relation to May '68?
• How far can an architecture conceived to "stimulate new behavior" escape its assimilation into commercial real-estate speculation (New Babylon's fate)?
