Many of the astronauts that White interviews argue that the experience would be a powerful political tonic, if you could somehow impel it upon the rulers of the planet. As Joseph Allen, a veteran of several Space-Shuttle flights, said:

A steady stream of world leaders should go into orbit. It would have a profound affect on their wisdom …. It is similar to the time of Copernicus; we have a broadened view of our place in the universe, and more educated view.

In his book Moondust, the author Andrew Smith argues that the moon landing was in some respects an art project, as gesture “as primitive as song”. We went there not so much to see the moon as to gaze back at Earth. It was “a unique opportunity to look at ourselves,” he writes, an accomplishment less of technology than of aesthetics, culture, and spirituality. “How madly, perfectly human.” Many of the astronauts White interviews in The Overview Effect lament the difficulty they have in putting their new perspective into words, of communicating its sheerly alien quality to other people. Gemini X astronaut Michael Collins concluded that that the ideal crew for an Apollo mission would have been a “philosopher, a priest, and a poet.” (“Unfortunately,” he added, “they would kill themselves trying to fly the spacecraft.”)
