Katharine Anthony's _Margaret Fuller_ is biography in new and fascinating form. "A psychological biography," Miss Anthony calls it, and she takes advantage of the theories of Freud and Jung to reveal new facts about the life of a woman long dead, by the process of submitting well known material to the psychoanalytic test. This is an engrossing game. There is something about it quite suggestive of the contrast between Sherlock Holmes and the more dull-witted detectives of Scotland Yard. Holmes, you remember, could come into a room after all the members of the force had pawed the evidence and interpret something new from the cigar ash on the table which had been to them just cigar ash, but was to Holmes convincing evidence that the crime had been committed by a red-haired man, six feet in height, born in Kentucky and an enrolled member of the Democratic Party. Other biographers were content to record the fact that Margaret Fuller was a nervous child who received all her early education at home from her father. There they paused, and it is just here that Miss Anthony leaps in to explain the exact emotional relation between father and daughter which simmered about in Margaret's subconsciousness and contributed to the convulsions of her early schooldays. It is fascinating to watch the skilled biographer reveal all sorts of facts about Margaret Fuller of which she herself had not the ghost of a notion. We can't say that the theory of the biographer is always convincing, although we must admit that her case is full and logical at every turn. To us it is just a little too logical. There is so much proof that we are rather inclined to believe that the theory is not altogether so. It is only fair to admit that Margaret seems to have been a Freudian herself long before there was a Freud. Again and again her own observations, quick, intuitive leaps, coincide almost exactly with theories worked out later by much more difficult and rational processes. Nathaniel Hawthorne, also, seems to have had some conception of the unconscious quite consistent with the most modern theorists, for he records a conversation between himself and Margaret Fuller in which they talked about "the experiences of early childhood, whose influence remains upon the character after the recollection of them has passed away."
