What are channels?

Famous quotes containing the word channels:

    The enthusiastic uprising of the people in our cause, is our great reliance; and we can not safely give it any check, even though it overflows, and runs in channels not laid down in any chart.
    Abraham Lincoln (1809–1865)

    Television is becoming a collage—there are so many channels that you move through them making a collage yourself. In that sense, everyone sees something a bit different.
    David Hockney (b. 1937)

    As every pool reflects the image of the sun, so every thought and thing restores us an image and creature of the supreme Good. The universe is perforated by a million channels for his activity. All things mount and mount.
    Ralph Waldo Emerson (1803–1882)
