Abstract
This chapter is about susceptibility to one type of division within our selves that can occur within self‐conscious experience and is present in certain mental disorders. This is the separation between experiencing oneself as subject and as agent. The chapter considers some disorders of self‐consciousness and examines the role that this particular division may play in those disorders. Companion to consciousness studies is not completed without attention to the philosophical psychopathology of self‐consciousness. The chapter also examines the case of verbal auditory hallucinations. Investigators often say that hallucinations involve “loss of ego boundaries” or “internal/external confusion”. The chapter presents a case of alienated self‐consciousness, and explores the phenomenon of thought insertion. According to the standard or traditional account of thought insertion, the patient is aware of her own thoughts, but denies that they are hers and attributes them to someone else. So, thought insertion certainly seems to constitute alienated awareness of one's own thoughts.
