Famous quotes containing the words anger and/or function:

    They have given us into the hand of new unhappy lords,
    Lords without anger and honour, who dare not carry their swords.
    They fight by shuffling papers; they have bright dead alien eyes;
    They look at our labour and laughter as a tired man looks at flies.
    Gilbert Keith Chesterton (1874–1936)

    For me being a poet is a job rather than an activity. I feel I have a function in society, neither more nor less meaningful than any other simple job. I feel it is part of my work to make poetry more accessible to people who have had their rights withdrawn from them.
    Jeni Couzyn (b. 1942)
