Famous quotes containing the words stress and/or field:

    A society which is clamoring for choice, which is filled with many articulate groups, each urging its own brand of salvation, its own variety of economic philosophy, will give each new generation no peace until all have chosen or gone under, unable to bear the conditions of choice. The stress is in our civilization.
    Margaret Mead (1901–1978)

    They talk about a woman’s sphere,
    As though it had a limit.
    There’s not a place in earth or heaven.
    There’s not a task to mankind given ...
    Without a woman in it.
    —Kate Field (1838–1896)
