Clutter is the disease of American writing. We are a society strangling in unnecessary words, circular constructions, pompous frills and meaningless jargon.
Who can understand the viscous language of everyday American commerce and enterprise...? Our national tendency is to inflate and thereby sound important. The airline pilot who announces that he is presently anticipating experiencing considerable precipitation wouldn't dream of saying that it may rain. The sentence is too simple—there must be something wrong with it.
But the secret of good writing is to strip every sentence to its cleanest components. Every word that serves no function, every long word that could be a short word, every adverb that carries the same meaning that's already in the verb, every passive construction that leaves the reader unsure of who is doing what—these are the thousand and one adulterants that weaken the strength of a sentence. And they usually occur, ironically, in proportion to education and rank…
Simplify, simplify. Thoreau said it, as we are so often reminded, and no American writer more consistently practiced what he preached. Open Walden to any page and you will find a man saying in a plain and orderly way what is on his mind:
I love to be alone. I never found the companion that was so companionable as solitude. We are for the most part more lonely when we go abroad among men than when we stay in our chambers. A man thinking or working is always alone, let him be where he will. Solitude is not measured by the miles of space that intervene between a man and his fellows. The really diligent student in one of the crowded hives of Cambridge College is as solitary as a dervish in the desert. [end of page 8]
How can the rest of us achieve such enviable freedom from clutter? The answer is to clear our heads of clutter. Clear thinking becomes clear writing: one can't exist without the other. It is impossible for a muddy thinker to write good English. He may get away with it for a paragraph or two, but soon the reader will be lost, and there is no sin so grave, for he will not easily be lured back.
