"Ignorance does not result from what we don’t know! Ignorance results from what we think we do know—but don’t! Most ignorant people are, in fact, quite certain."
This is a hard sell and wouldn't preach that well here in America where Certainty has been elevated to sacred status and ignorance applies to everyone but us? But goodness gracious does it ever need to sink in as a desperately needed truth for a people that have been made to think of themselves as God's gift to the rest of the world.
