It has been observed that Henry James's prefaces for the New York Edition arc often unreliable as guides to the finished stories because they are so concerned with the germinations of his ideas. The very emphasis upon beginnings is presumably James's way of insisting upon the distance and the labor between the germ and the maturity of a work, a point which he explicitly invites us to ponder in the Preface to The Wings of the Dove:
... some acute mind ought surely to have worked out by this time the “law” of the degree in which the artist's energy fairly depends upon his fallibility. How much and how often, and in what connexions and with what almost infinite variety, must he be a dupe, that of his prime object, to be at all measurably a master, that of his actual substitute for it-or in other words at all appreciably to exist? He places, after an earnest survey, the piers of his bridge-he has at least sounded deep enough, heaven knows, for their brave position; yet the bridge spans the stream, after the fact, in apparently complete independence of these properties, the principal grace of the original design.
