Artaud has shown us that to be a poet is to be more than marginal, it is to be alienated from our society to the point of madness. In this passage, Artaud is discussing how the political structure shapes and defines identity. This political structure, this world of mother-father, Artaud concludes, is turning the whole system of the world malignantly sustained by the most sombre organization. It may be breakthrough. In this passage, Deleuze and Guatteri are discussing schizophrenia, the schizophrenia, for instance, that must result when the art body is separated from the political body.
Schizophrenia is that which stops the flow.
Baudelaire, Rimbaud, Artaud and their ilk viewed their writing, every aspect, content and structure, because their very lives, life-decisions, as politically defined. Since the book-chain stores, who are increasingly dominating that market, buy mainly from the six large publishing houses, those publishers monopolize distribution. Not only distribution. The major publishing houses have both immense publicity budgets and equal access to major media. Generally, the majors, whose interest is increasingly in sales, publish only those fictional and poetic texts written according to certain rules, regulations governing structure, style and language, texts written in order to sell.
