It is an old observation that the best writers sometimes disregard the rules of rhetoric.
When they do so, however, the reader will usually find in the sentence some compensating
merit, attained at the cost of the violation. Unless he is certain of doing as well,

write plain English adequate for everyday uses, let him look, for the secrets of style, to
the study of the masters of literature.
