Knowledge that is common only amongst those who have some...
It's common sense (c.s.)...

-Not to tailgate. (Not c.s. if you've never ran into someone else's trunk.)
-Not to lean over a rail. (Not c.s. if you haven't leaned over and busted your face before.)
-Not to feed the wild animals. (Not c.s. unless you're missing a hand or two.)

1) The sense of logical reasoning and problem solving skills as applied to practical situations that all inteligent beings should and usually do have. Whether they actually use it is another issue.

2)A pamphlet written by none other than Thomas Paine prior to the American Revolution. It railed against British policies in it's colonies, and got many colonists (the intelligent and/or educated ones who could read, anyway) to question British rule of America. This, of course, was yet another paving stone on the road to revolution and the creation of the United States of America as we know it today.
1) "You don't need education to know that's stupid... just use your common sense."

2) The man read Common Sense by Thomas Paine. Then, he decided to go burn his stamps and not buy any more British tea.
