Matching Quote

"Addison writes with the ease of a gentleman. His readers fancy that a wise and accomplished companion is talking to them; so that he insinuates his sentiments and taste into their minds by an imperceptible influence. Johnson writes like a teacher. He dictates to his readers as if from an academical chair. They attend with awe and admiration; and his precepts are impressed upon them by his commanding eloquence. Addison's style, like a light wine, pleases everybody from the first. Johnson's, like a liquor of more body, seems too strong at first, but, by degrees, is highly relished."

-James Boswell
