Abstract
This paper aims to consider the main features of the philosophy of linguistics proposed by Deleuze and Guattari, which emerges from the criticisms directed at what in A Thousand Plateaus they call ‘postulates of linguistics’. The paper focuses on the transition from the Saussurean concept of system and from the connected notion of structure to Deleuze and Guattari's concept of machine. More precisely, the purpose of the paper lies, on the one hand, in showing in which sense Deleuze and Guattari claim that language is not a ‘structure’ but a ‘machine’ and why, accordingly, they maintain that the mentioned ‘postulates of linguistics’ must be refused; on the other hand, the paper represents an attempt at placing Deleuze and Guattari's position in the context of contemporary linguistics.
