Famous quotes containing the word undefined:

    An island always pleases my imagination, even the smallest, as a small continent and integral portion of the globe. I have a fancy for building my hut on one. Even a bare, grassy isle, which I can see entirely over at a glance, has some undefined and mysterious charm for me.
    Henry David Thoreau (1817–1862)

    That undefined and mingled hum,
    Voice of the desert never dumb!
    James Hogg (1770–1835)

    I have the strong impression that contemporary middle-class women do seem prone to feelings of inadequacy. We worry that we do not measure up to some undefined level, some mythical idealized female standard. When we see some women juggling with apparent ease, we suspect that we are grossly inadequate for our own obvious struggles.
    Faye J. Crosby (20th century)
