Famous quotes containing the words rail, term and/or light:

    In my conscience I believe the baggage loves me, for she never speaks well of me herself, nor suffers any body else to rail at me.
    William Congreve (1670–1729)

    We term sleep a death ... by which we may be literally said to die daily; in fine, so like death, I dare not trust it without my prayers.
    Thomas Browne (1605–1682)

    Our roots are in the dark; the earth is our country. Why did we look up for blessing—instead of around, and down? What hope we have lies there. Not in the sky full of orbiting spy-eyes and weaponry, but in the earth we have looked down upon. Not from above, but from below. Not in the light that blinds, but in the dark that nourishes, where human beings grow human souls.
    Ursula K. Le Guin (b. 1929)
