'Treatise on Slobber and Eternity') is a 1951 French avant-garde film by Isidore Isou that grew out of the Lettrist movement in Paris.

The first chapter, "Principle" (French: "Le principe"), displays people walking around the streets of Paris as the audio track presents an argument at a film society.

Actors Daniel Gélin and Danièle Delorme were filmed at home with their children, as was Marcel Achard, who was led to believe it was for television.

Isou was unable to enter Venom and Eternity into the festival but harassed officials until they allowed him to present his film at the Vox Theater.

[7][9] Accounts of the scandalous response described a rioting audience and police officers using fire hoses on the crowd, but these stories are largely apocryphal.

[7][10] As soon as Venom and Eternity was completed, the Ciné-Club Avant-Garde 52 showed it at the Musée de l'Homme in Paris.

It is the most complete version available but does not include the title cards, credits, and text intended by Isou to clearly separate the film into three chapters.

[13] Kino Lorber released the film in 2007 as part of its DVD collection Avant-Garde 2: Experimental Cinema 1928–1954.
