It Could Still Be Out There, Somewhere

In the Feb. 12th, 2007's New Yorker on p. 62 there was a quick story to illustrate a point. It involved space ships and mutants from "Orphans of the Sky" by Robert Heinlein. You can read it for the details, sorry I don't have a link. Try the library.
Let me jump to the moral of the story.
".....it has retained a hold of Paul's imagination: he always remembers that, however certain he may be about something, however airtight an argument appears or however fundamental an intuition, there is always a chance that both are completely wrong, and that reality lies in some other place that he hasn't looked because he doesn't know it's there."
Keep those eyes and ears sharp and keep that brain open. You don't want to be the only one who still thinks the earth is flat, or that war is necessary or that money buys happiness. Reality is still around the corner. Enjoy the exploration!
