The documents are abundant for an analysis of Daudet such as Sainte-Beuve would have undertaken with avidity; they are more abundant indeed than for any other contemporary French man of letters even in these days of unhesitating self-revelation; and they are also of an absolutely impregnable authenticity. M. Ernest Daudet has written a whole volume to tell us all about his brother's boyhood and youth and early manhood and first steps in literature. M. Leon Daudet has written another solid tome to tell us all about his father's literary principles and family life and later years and death. Daudet himself put forth a pair of pleasant books of personal gossip about himself, narrating his relations with his fellow authors and recording the circumstances under which he came to compose each of his earlier stories. Montaigne--whose "Essays" was Daudet's bedside book and who may be accepted not unfairly as an authority upon egotism--assures us that "there is no description so difficult, nor doubtless of so great utility, as that of one's self." And Daudet's own interest in himself is not unlike Montaigne's,--it is open, innocent and illuminating. Cuvier may have been able to reconstruct an extinct monster from the inspection of a single bone; but it is a harder task to revive the figure of a man, even by the aid of these family testimonies, this self-analysis, the diligence of countless interviewers of all nationalities, and indiscretion of a friend like Edmond de Goncourt (who seems to have acted on the theory that it is the whole duty of man to take notes of the talk of his fellows for prompt publication). Yet we have ample material to enable us to trace Daudet's heredity, and to estimate the influence of his environment in the days of his youth, and to allow for the effect which certain of his own physical peculiarities must have had upon his exercise of his art. His near-sightedness, for example,--would not Sainte-Beuve have seized upon this as significant? Would he not have seen in this a possible source of Daudet's mastery of description? And the spasms of pain borne bravely and uncomplainingly, the long agony of his later years, what mark has this left on his work, how far is it responsible for a modification of his attitude,--for the change from the careless gaiety of "Tartarin of Tarascon" to the sombre satire of "Port-Tarascon"? What caused the joyous story-teller of the "Letters from my Mill" to develop into the bitter iconoclast of the "Immortal."
