Famous quotes containing the words sneeze and/or reflex:

    Frau Stöhr ... began to talk about how fascinating it was to cough.... Sneezing was much the same thing. You kept on wanting to sneeze until you simply couldn’t stand it any longer; you looked as if you were tipsy; you drew a couple of breaths, then out it came, and you forgot everything else in the bliss of the sensation. Sometimes the explosion repeated itself two or three times. That was the sort of pleasure life gave you free of charge.
    Thomas Mann (1875–1955)

    No sooner does a great man depart, and leave his character as public property, than a crowd of little men rushes towards it. There they are gathered together, blinking up to it with such vision as they have, scanning it from afar, hovering round it this way and that, each cunningly endeavouring, by all arts, to catch some reflex of it in the little mirror of himself.
    Thomas Carlyle (1795–1881)
