Ellen Bass and Laura Davis, co-authors of "The Courage to Heal" (1988), are described as "champions of survivorship" by Frederick Crews, who considers Freud the key influence upon them, although in his view they are indebted not to classic psychoanalysis but to "the pre-psychoanalytic Freud... who supposedly took pity on his hysterical patients, found that they were all harboring memories of early abuse... and cured them by unknotting their repression." Crews sees Freud as having anticipated the recovered memory movement by emphasizing "mechanical cause-and-effect relations between symptomatology and the premature stimulation of one body zone or another", and with pioneering its "technique of thematically matching a patient's symptom with a sexually symmetrical 'memory.'" Crews believes that Freud's confidence in accurate recall of early memories anticipates the theories of recovered memory therapists such as Lenore Terr, which in his view have led to people being wrongfully imprisoned or involved in litigation.
