     We can achieve knowledge either actively or passively (被动地). We achieve it actively by direct

experience, by testing and proving an idea, or by reasoning.

     We achieve knowledge passively by being told by someone else. Most of the learning that takes place

in the classroom and the kind that happens when we watch TV or read newspapers or magazines is

passive. Conditioned as we are to passive learning, it's not surprising that we depend on it in our everyday

communication with friends and co-workers.

     Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told

even when it is little more than hearsay and rumor (谣言).

     Did you ever play the game Rumor? It begins when one person writes down a message but doesn't

show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn,

whispers it to still another, and so on, through all the people playing the game. The last person writes down

the message word for word as he or she hears it. Then the two written statements are compared. Typically,

the original message has changed.

     That's what happens in daily life. The simple fact that people repeat a story in their own words changes

the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a

story, trying to improve on it, stamping (打上标记) it with their own personal style. Yet those who hear it

think they know.

     This process is also found among scholars and authors: A statement of opinion by one writer may be

re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue,

unless it occurs to someone to question the facts on which the original writer based his opinion or to

challenge the interpretation he placed upon those facts.
