What are sides?

Famous quotes containing the word sides:

    I see before me now a traveling army halting,
    Below a fertile valley spread, with barns and the orchards of summer,
    Behind, the terraced sides of a mountain, abrupt, in places rising high,
    Walt Whitman (1819–1892)

    The life of man is a self-evolving circle, which, from a ring imperceptibly small, rushes on all sides outwards to new and larger circles, and that without end.
    Ralph Waldo Emerson (1803–1882)
