Famous quotes containing the words traffic, flow and/or theory:

    Poems stirred
    into paper coffee-cups, eaten
    with petals on rye in the
    sun—the cold shadows in back,
    and the traffic grinding the
    borders of spring ...
    Denise Levertov (b. 1923)

    Our sense of these things changes and they change,
    Not as in metaphor, but in our sense
    Of them. So sense exceeds all metaphor.
    It exceeds the heavy changes of the light.
    It is like a flow of meanings with no speech
    And of as many meanings as of men.
    Wallace Stevens (1879–1955)

    There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.
    —A.J. (Alfred Jules)
