catch-22 was an old wwii term used to describe the theory for the belief that if a patient thought he might be crazy he must be sane enough to be able to think that. the awareness of a separateness is usally termed a conscience. many patients override its function and have it push a panic button. the proper, healthy is to pull the eject handle. that is if the host entity is truly at risk to begin with, else it has been discarded for naught.
