A first precaution for writers: in every text, every piece, every paragraph to check whether the central motif stands out clearly enough. Anyone wishing to express something is so carried away by it that he ceases to reflect on it.Adorno, Minima Moralia, page 85
No improvement is too small or trivial to be worthwhile. Of a hundred alterations each may seem trifling or pedantic by itself; together they can raise the text to a new level.
When several sentences seem like variations on the same idea, they often only represent different attempts to grasp something the author has not yet mastered. Then the best formulation should be chosen and developed further. It is part of the technique of writing to be able to discard ideas, even fertile ones, if the construction demands it.
The prudence that restrains us from venturing too far ahead in a sentence, is usually only an agent of social control, and so of stupefaction.
