The schizoanalytic model of the psyche is that of a machine, or a set of machines: the desiring-machines. Describing it is one of the most important tasks of this book, since both the internal and the external critiques of the Oedipus follow directly from the ways schizoanalysis understands the psyc~e to operate. It is also one of the most difficult tasks, and I ask readers to bear with me for the next few pages. In the hope of facilitating comprehension, I have separated the presentation of the model from its mobilization in the critique of Oedipus. The disadvantage of such a g~bit is that the model standing alone will appear somewhat abstract; the advantage is that we will be able to concentrate on the model itself before it is brought to bear on aspects of psychoanalysis that are often complex and difficult to understand in their own right.
