"I have the feeling that every man's biography is at his own expense. He furnishes not only the facts, but the report. I mean that all biography is autobiography. It is only what he tells of himself that comes to be known and believed." So writes the man whose life we are to pass in review, and it is certainly as true of him as of any author we could name. He delineates himself so perfectly in his various writings that the careful reader sees his nature just as it was in all its essentials, and has little more to learn than those human accidents which individualize him in space and time. About all these accidents we have a natural and pardonable curiosity.
