Here was a big constructive imagination; here was a mere doctor laying bare the origins of Greek drama as no classical scholar had ever done, teaching the anthropologist what was really meant by his totem and taboo, probing the mysteries of sin, of sanctity, of sacrament—a man who, because he understood, purged the human spirit from fear. I have no confidence in psycho-analysis as a method of therapeutics ... but I am equally sure that for generations almost every branch of human knowledge will be enriched and illumined by the imagination of Freud.
