Psychosis is a special type of confusion with its own reality, an internal reality that is consistent only with itself. It does feature a connected, ever-flowing “stream of thought,” to use William James’s term (not a stream of consciousness, a phrase that James came to dislike). In his Principles of Psychology, James claimed that all of us carry on a virtually continuous internal conversation. While a psychotic’s internal stream may seem bizarre and disconnected, it has its own internal logic. Anyone could follow it, according to James, if they were standing in the waters of the stream.
