From Dialogues, a text in which Gilles Deluze is in conversation with Clair Parnett. In this text Delueze says:

We've only said two things against psychonalysis: that it breaks up all productions of desire and crushes all formation of utterances. In this way it wrecks both aspects of the assemblage: the machinic assemblage of desire and the collective assemblage of enunciation.The fact is that psychonalysis talks a lot about the unconscious--it even discovered it. But in practice, it always diminishes, destroys and exorcises it. The unconscious is understood as a negative it's the enemy. (p.76)
