Joseph Beuys once stacked grocery items as political sculpture, turning margarine and stockfish into artifacts of economic critique. Now conservators at SMAK in Ghent are grappling with how to preserve Wirtschaftswerte, a piece built from perishable goods whose decay was arguably the point. The problem is not merely technical. It is philosophical: what are you actually preserving when you preserve something designed to change?
Decay as Medium: From Butter to Surrealist Letters
The same week the Beuys conservation story broke, newly surfaced letters by the long-overlooked Surrealist Jacqueline Lamba revealed a love affair with Frida Kahlo, recovering a relationship the historical record had allowed to quietly spoil. The parallel is structural. In both cases, something fragile and intimate was never meant to last in its original form, and the act of preservation is also an act of transformation. You are not saving the thing. You are building an argument about what it meant. Tom Sachs, discussing sympathetic magic and Joseph Beuys specifically, describes the artist's relationship to materials as theological: the fat and felt are not symbolic of warmth, they are warmth, captured and made permanent. Conservation of Beuys, by that logic, is contradictory. You are freezing a philosophy of flux.
The Museum as Incompatible Infrastructure
The institutional dimension sharpens when you place these stories next to Hyperallergic's investigation into why dozens of museums still hold works sold by a convicted antiquities dealer. The art world's preservation instinct, it turns out, applies selectively. Butter sculptures by a radical German artist demand expensive conservation effort. Looted antiquities sit quietly in galleries for decades after provenance problems surface. What institutions choose to preserve, stabilize, or let decay is never a neutral choice. It is always a political one. A 2026 paper in arXiv's CS.AI by Moldoveanu and Baum on adversarial social epistemology is relevant here: they argue that assemblies of humans and LLMs generate knowledge through adversarial contestation, not consensus. The same is true of the art archive. What survives is not what was best preserved. It is what was most fiercely argued for.
