To compensate a little for the treachery and weakness of my memory, so extreme that it has happened to me more than once to pick up again...books which I have read carefully a few years before. I have adopted the habit for some time now of adding at the end of each book the time I finished reading it and the judgment I have derived of it as a whole, so that this may represent to me at least the sense and general idea I had conceived of the author in reading it.
