The journalist developed into a social type, exemplified in the London of the years of our concern [ca. 1715] by Defoe, Addison, Steele, Swift, and a large group of lesser lights. Their common characteristic is allegiance to a political party....What journalists of every type see as their proper task is to form public opinion.
