Famous quotes containing the words air and/or core:

    “To be worst,
    The lowest and most dejected thing of fortune,
    Stands still in esperance, lives not in fear.
    The lamentable change is from the best;
    The worst returns to laughter. Welcome, then,
    Thou unsubstantial air that I embrace!
    The wretch that thou hast blown unto the worst
    Owes nothing to thy blasts.”
    —William Shakespeare (1564–1616)

    “Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today—but the core of science fiction, its essence ... has become crucial to our salvation if we are to be saved at all.”
    —Isaac Asimov (1920–1992)
