Famous quotes containing the word roads:

    “All roads are blocked to a philosophy which reduces everything to the word “no.” To “no” there is only one answer and that is “yes.” Nihilism has no substance. There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing. Man lives more by affirmation than by bread.”
    —Victor Hugo (1802–1885)

    “Lift your eyes
    Where the roads dip and where the roads rise
    Seek only there
    Where the grey light meets the green air
    The hermit’s chapel, the pilgrim’s prayer.”
    —T.S. (Thomas Stearns)

    “Then the master said to the slave, Go out into the roads and lanes, and compel people to come in, so that my house may be filled.”
    —Bible: New Testament, Luke 14:23.
