Phil Plait, over at Bad Astronomy, says that Carl Sagan’s essay, "Reflections on a Mote of Dust" (collected in Pale Blue Dot) ought to be required reading for every human being on the planet.  I agree, and add that this video, which combines Sagan’s beautiful essay with music and imagery, ought to be required viewing for all of us.

The video’s beneath the fold. Enjoy.
