Famous quotes containing the word safety:
“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)
“There is always safety in valor.”
—Ralph Waldo Emerson (1803–1882)
“To emancipate [the slaves] entirely throughout the Union cannot, I conceive, be thought of, consistently with the safety of the country.”
—Frances Trollope (1780–1863)
