The preface is usually that part of a book which can most safely be omitted. It usually represents that efflorescent manifestation of egotism which an author, after working hard, cannot spare either himself or his readers. More often than not the readers spare themselves. When, however, the writer is a daily perpetrator of high treason, his introductory remarks may command from the English public that kind of awful veneration with which £5000 confessions are perused in the Sunday newspapers, quite frequently after the narrator has taken his last leap in the dark.
