The corpus of Kafka's writing, they argue, is ‘arhizome, a burrow’ (K 7)—an uncentered and meandering growth like crab grass, a complex, aleatory network of pathways like a rabbit warren. Arhizome, as Deleuze and Guattari explain inRhizome: an Introduction (1976), is the antithesis of a root-tree structure, or ‘arborescence’, the structural model which has dominated Western thought from Porphyrian trees, to Linnaean taxonomies, to Chomskyan sentence diagrams.
