Some Clowning Around is Nothing to Get Hysterical About

...the question of "Che vuoi?" defines the position of hysteria. The hysteric is never clear what the Other wants and is therefore always plagued by a kind of self-doubt, manifest in a recurrent questioning. In a straightforward hysteria the subject believes that what the Other wants from him or her is love. In obsessional neurosis, which is a sub-set of hysteria, the subject believes that what the Other wants is work, and so the obsessional devotes him or herself to frentic activity... Despite its everyday associations with so-called sexual deviancy, perversion is also a technical term that the Lacanian psychoaalysis uses to designate a certainty that a subject knows what the Other wants. The pervert is therefore defined by a lack of questioning. He or she is convinced of the meaning of the desire of the Other.
