Famous quotes containing the word cities:

    No doubt I shall go on writing, stumbling across tundras of unmeaning, planting words like bloody flags in my wake. Loose ends, things unrelated, shifts, nightmare journeys, cities arrived at and left, meetings, desertions, betrayals, all manner of unions, adulteries, triumphs, defeats ... these are the facts.
    Alexander Trocchi (1925–1983)

    Books may be burned and cities sacked, but truth like the yearning for freedom, lives in the hearts of humble men and women. The ultimate victory, the ultimate victory of tomorrow is with democracy; and true democracy with education, for no people in all the world can be kept eternally ignorant or eternally enslaved.
    Franklin D. Roosevelt (1882–1945)

    We are a most solitary people, and we live, repelled by one another, in the gray, outcast cities of Cain.
    Edward Dahlberg (1900–1977)
