A Lacanian perspective on psychotic hallucinations

This article gives an overview of the psychiatric approach to psychotic hallucinations and discusses Lacan’s conceptual break from this paradigm. Rejecting the traditional focus on the unreality of hallucinatory perceptions, Lacan examines the effects that psychotic hallucinations have on the person who experiences them. He develops an alternative theoretical framework which indicates that psychosis is characterized by the incapacity to signify one’s own existence as a subject in relation to the Other. Lacan’s different perspectives on hallucinations are discussed in terms of the logic of signification as the constitution of subjectivity and as a manifestation of the object a and jouissance, and also in terms of his theory of the sinthome.
