Famous quotes containing the words working and/or fluid:
“English audiences of working people are like an instrument that responds to the player. Thought ripples up and down them, and if in some heart the speaker strikes a dissonance there is a swift answer. Always the voice speaks from gallery or pit, the terrible voice which detaches itself in every English crowd, full of caustic wit, full of irony or, maybe, approval.”
—Mary Heaton Vorse (1874–1966)
“There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.”
—Ralph Waldo Emerson (1803–1882)
