Famous quotes containing the words signal, passed and/or danger:
“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)
“See, there is a place by me where you shall stand on the rock; and while my glory passes by I will put you in a cleft of the rock, and I will cover you with my hand until I have passed by;
then I will take away my hand, and you shall see my back; but my face shall not be seen.””
—Bible: Hebrew, Exodus 33:21-23.
“Now you courtly dames and knights,
That study only strange delights,
Though you scorn the home-spun gray
And revel in your rich array;
Though your tongues dissemble deep
And can your heads from danger keep:
Yet for all your pomp and train,
Securer lives the silly swain.”
—Thomas Campion (1567–1620)
