     It is true that good writers rewrite and rewrite and then rewrite some more. But in order to work up

the desire to rewrite, it is important to learn to like what you write at the early stage.

     I am surprised at the number of famous writers I know who say that they so dislike reading their own

writing later that they even hate to look over the publishers' opinions. One reason we may dislike reading

our own work is that we're often disappointed that the rich ideas in our minds seem very thin and plain

when first written down. Jerry Fodor and Steven Pinker suggest that this fact may be a result of how our

minds work.

     Different from popular belief, we do not usually think in the words and sentences of ordinary language

but in symbols for ideas (known as'mentalese'),and writing our ideas down is an act of translation from

that symbolic language. But while mentalese contains our thoughts in the form of a complex tapestry (织锦),writing can only be composed one thread at a time. Therefore it should not be surprising that our first

attempt at expressing ideas should look so simple. It is only by repeatedly rewriting that we produce new

threads and connect them to get closer to the ideas formed in our minds.

     When people write as if some strict critics (批评家) are looking over their shoulder, they are so

worried about what this critic might say that they get stuck before they even start. Peter Elbow makes an

excellent suggestion to deal with this problem. When writing we should have two different minds. At the

first stage, we should see every idea, as well as the words we use to express it, as wonderful and worth

putting down. It is only during rewrites that we should examine what we excitedly wrote in the first stage

and check for weaknesses.
