Famous quotes containing the words alarm and/or signal:
“Generally speaking, the political news, whether domestic or foreign, might be written today for the next ten years with sufficient accuracy. Most revolutions in society have not power to interest, still less alarm us; but tell me that our rivers are drying up, or the genus pine dying out in the country, and I might attend.”

“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
