Famous quotes containing the words surface and/or variants:

    “All the aspects of this desert are beautiful, whether you behold it in fair weather or foul, or when the sun is just breaking out after a storm, and shining on its moist surface in the distance, it is so white, and pure, and level, and each slight inequality and track is so distinctly revealed; and when your eyes slide off this, they fall on the ocean.”
    —Henry David Thoreau (1817–1862)

    “Nationalist pride, like other variants of pride, can be a substitute for self-respect.”
    —Eric Hoffer (1902–1983)
