Famous quotes containing the words time and/or events:

    “Where have you gone? The tide is over you,
    The turn of midnight water’s over you,
    As Time is over you, and mystery,
    And memory, the flood that does not flow.”
    —Kenneth Slessor (1901–1971)

    “It is clear to everyone that astronomy at all events compels the soul to look upwards, and draws it from the things of this world to the other.”
    —Plato (c. 427–347 B.C.)
