单项选择题

So far as I know, Miss Hannah Arendt was the first person to define the essential difference between work and labor. To be happy, a man must feel, firstly, free and, secondly, important. He cannot be really happy if he is compelled by society to do what he does not enjoy doing, or if what he enjoys doing is ignored by society as of no value or importance. In a society where slavery in the strict sense has been abolished, the sign that what a man does is of social value is that he is paid money to do it, but a laborer today can rightly be called a wage slave. A man is a laborer if the job society offers him is of no interest to himself but he is compelled to take it by the necessity of earning a living and supporting his family.

The antithesis to labor is play. When we play a game, we enjoy what we are doing, otherwise we should not play it, but it is a purely private activity; society could not care less whether we play it or not.

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 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 hours 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 the fewer hours he has to spend laboring, and the more hours he is free to play, the better.

According to the passage, what is society’s attitude toward the game we play().

A. Society regards play as another kind of labor.

B. Society doesn’t care what we play at all.

C. Society forbids us to play any game.

D. Society cares for private games very much.
