VII. Translation from English into Chinese

71. Between labor and play stands work. A man is a worker if he is personally interested in the job which society pays him to do; what from the point of view of society is necessary labor is from his own point of view voluntary play. Whether a job is to be classified as labor or work depends, not on the job itself, but on the tastes of the individual who undertakes it. The difference does not, for example, coincide with the difference between a manual and a mental job; a gardener or a cobbler may be a worker, a bank clerk a laborer. Which a man is can be seen from his attitude toward leisure. To a worker, leisure means simply the hour he needs to relax and rest in order to work efficiently. He is therefore more likely to take too little leisure than too much; workers die of coronaries and forget their wives’ birthdays. To the laborer, on the other hand, leisure means freedom from compulsion, so that it is natural for him to imagine that the fewer hours he has to spend laboring, and the more hours he is free to play, the better.
