Klein approaches psychosis via anxiety. According to Bion, the psychotic personality has its origin in the fragmentation followed by the expulsion of the means by which the ego knows reality that is, the fragmentation and expulsion of the senses, consciousness, and thinking. From then on there will be an ever-widening divergence between the psychotic and the non-psychotic parts of his personality, and Bion thinks that people will not understand psychosis until they recognize this. Bion points out that the psychotic patient who is able to attend for therapy will have also a non-psychotic personality, and this is, for us, a gain. Mrs. L belongs to a particular group of patients described by Bion who cannot bear the dominance of the reality principle, but who do not completely evade frustration either. They have thrown light on the obscure territory of psychosis, and they will, O'Shaughnessy Edna feel sure, illuminate it still further in the future.
