It is like wearing a mask. It gives rise to a feeling of in sincerity. It does not show a fine sense of style but the vulgar instinct to display. Many essayists have written about style, and most of them. If you wish me to weep, you yourself must feel grief, said Horace in his Art of Poetry.
Nothing is so forcible as truth plainly told.
On the other hand, we might write a poem made up of lines that sound prettily on the tongue, but so insipid as not to linger a moment in memory. The style in which it is written is not designed to make us see the writer, but his subject and thoughts. Prose does not wish to compete with poetry. Prose will not turn away from rhythm if rhythm is necessary to its purpose, but it will seek rather a modulated utterance, a medium between prose and poetry. It will seek to be lucid and easy, but when opportunity offers it will also be graceful, witty, pathetic or imaginative.
