You no longer need a good book, which he really likes, to keep him from his prayers or his work or his sleep; a column of advertisements in yesterday’s paper will do. You can make him waste his time not only in conversation he enjoys with people whom he likes, but in conversations with those he cares nothing about on subjects that bore him. You can make him do nothing at all for long periods. You can keep him up late at night, not roistering, but staring at a dead fire in a cold room.
