A good Cause doth not want any Bitterness to support it, as a bad one cannot subsist without it. It is indeed observable, that an Author is scurrilous in proportion as he is dull; and seems rather to be in a Passion, because he cannot find out what to say for his own Opinion, than because he has discovered any pernicious Absurdities in that of his Antagonists.
Joseph Addison (1672–1719) English essayist, poet, statesman
Essay (1716-06-29), The Freeholder, No. 55
