Famous quotes containing the words primitive and/or pit:
“How far men go for the material of their houses! The inhabitants of the most civilized cities, in all ages, send into far, primitive forests, beyond the bounds of their civilization, where the moose and bear and savage dwell, for their pine boards for ordinary use. And, on the other hand, the savage soon receives from cities iron arrow-points, hatchets, and guns, to point his savageness with.”
—Henry David Thoreau (1817–1862)
“Personality is the glitter that sends your little gleam across the footlights and the orchestra pit into that big black space where the audience is.”
—Mae West (1892–1980)
