Famous quotes containing the words brown and/or nature:

    Unreal city,
    Under the brown fog of a winter dawn,
    A crowd flowed over London Bridge, so many,
    I had not thought death had undone so many.
    —T.S. (Thomas Stearns)

    [University students] hated the hypocrisy of adult society, the rigidity of its political institutions, the impersonality of its bureaucracies. They sought to create a society that places human values before materialistic ones, that has a little less head and a little more heart, that is dominated by self-interest and loves its neighbor more. And they were persuaded that group protest of a militant nature would advance those goals.
    Muriel Beadle (b. 1915)
