In taking up Deleuze's differential diagnosis by observing Masoch's literary practice and extracting his libidinal principles of imperatives, contracts, fetishism and rituals, I demonstrate Deleuzian libidinal symptomatology as a specific semiotics in the service of schizoanalysis. I shall argue that in Masoch the schizoanalytic curettage of the unconscious is executed as schizoid waiting where the fleeting outer symptoms of pain–pleasure reveal the masochist's desired inner splitting of the senses.Several critical-clinical inroads to the schizoanalytic project can be envisaged. Initially, Masoch's visionary (...) concept of sexualised world history is supported by his strategic move to the law of the oral mother, yet then extended by Deleuze's concept of (inter)maternal symbolic which speculates on the fantasised rebirth of a sexless or hermaphroditic man. Finally, the parodic enactment of eros and thanatos functions as technique of dialectical disguise within the masochist's scheme of practising libidinal liberation.Masochism considered as a state of bodily experimentation which turns the oedipal law upside down, emerges as a distinct literary genre in Deleuzian aesthetics.
