     Silence is unnatural to man. He begins life with a cry and ends it in stillness. In between be does all he can

to make a noise in the world, and be fears silence more than anything else. Even his conversation is an attempt

to prevent a fearful silence. If he is introduced to another person, and is number of pauses occur in the

conversation, he regards him-self as a failure,a worthless person, and is full of envy of the emptiest- headed

chatterbox (喋喋不休的人).He knows that ninety nine percent of human conversation means no more than the

buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure

(蜡塑人像).

     The aim of conversation is not. For the most part, to communicate ideas; it is to keep up the buzzing sound. There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the

continuous noise made by a mosquito (蚊子). But at a dinner party one would rather be a mosquito than a quiet

person. Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind. He would

be a foolish man if he waited until he had a wise thought to take part in the buzzing with his neighbors.

     Those who hate to pick up the weather as a conversational opening seem to me not to know the reason

why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything

new. Some of them are content if they are merely allowed to go on making a noise into other people's ears,

though they have nothing to tell them except that they have seen two or three new plays or that they had food

in a Swiss hotel. At the end of an evening, during which they have said nothing meaningful for a long time.

They just prove themselves to be successful conservationists.
