Writers address a number of features and characteristics of two subjects, persons, places, and events by contrasting them from one point to another. While the major purpose of contrast is to elucidate ideas and clear their meanings, readers can easily understand through this device what is going to happen next. Through opposite and contrasting ideas, writers make their arguments stronger, thus making them more memorable for readers due to emphasis placed on them. In addition, contrasting ideas shock the audience , heighten drama , and produce balanced structures in literary works.
“Stormy and wet, stormy and wet; and mud, mud, mud, deep in all the streets. Day after day, a vast heavy veil had been driving over London from the East, and it drove still, as if in the East there were an Eternity of cloud and wind. So furious had been the gusts, that high buildings in town had had the lead stripped off their roofs; and in the country, trees had been torn up, and sails of windmills carried away; and gloomy accounts had come in from the coast, of shipwreck and death. Violent blasts of rain had accompanied these rages of wind, and the day just closed as I sat down to read had been the worst of all.”
