Famous quotes containing the words sequence of, sequence and/or events:

    It isn’t that you subordinate your ideas to the force of the facts in autobiography but that you construct a sequence of stories to bind up the facts with a persuasive hypothesis that unravels your history’s meaning.
    Philip Roth (b. 1933)

    We have defined a story as a narrative of events arranged in their time-sequence. A plot is also a narrative of events, the emphasis falling on causality. “The king died and then the queen died” is a story. “The king died, and then the queen died of grief” is a plot. The time sequence is preserved, but the sense of causality overshadows it.
    —E.M. (Edward Morgan)

    A curious thing about atrocity stories is that they mirror, instead of the events they purport to describe, the extent of the hatred of the people that tell them.
    Still, you can’t listen unmoved to tales of misery and murder.
    John Dos Passos (1896–1970)
