Famous quotes containing the words disease and/or relevance:
“It is useless to check the vain dunce who has caught the mania of scribbling, whether prose or poetry, canzonets or criticisms,—let such a one go on till the disease exhausts itself. Opposition like water, thrown on burning oil, but increases the evil, because a person of weak judgment will seldom listen to reason, but become obstinate under reproof.”
—Sarah Josepha Buell Hale 1788–1879, U.S. novelist, poet and women’s magazine editor. American Ladies Magazine, pp. 36-40 (December 1828)
“Wherever the relevance of speech is at stake, matters become political by definition, for speech is what makes man a political being.”
—Hannah Arendt (1906–1975)
