Famous quotes containing the words cloud and/or seeding:
“Misfortune is never mournful to the soul that accepts it; for such do always see that every cloud is an angel’s face. Every man deems that he has precisely the trials and temptations which are the hardest of all others for him to bear; but they are so, simply because they are the very ones he most needs.”
—Lydia M. Child (1802–1880)
“Propaganda has a bad name, but its root meaning is simply to disseminate through a medium, and all writing therefore is propaganda for something. It’s a seeding of the self in the consciousness of others.”
—Elizabeth Drew (1887–1965)
