What is point source?

Famous quotes containing the words point and/or source:

    In the labyrinth of a difficult text, we find unmarked forks in the path, detours, blind alleys, loops that deliver us back to our point of entry, and finally the monster who whispers an unintelligible truth in our ears.
    Mason Cooley (b. 1927)

    I am no source of honey
    So why should they turn on me?
    Tomorrow I will be sweet God, I will set them free.

    The box is only temporary.
    Sylvia Plath (1932–1963)
