If we instituted a mandatory course in "Good, logical thinking" beginning in, say, 4th grade, it would soon be attacked by parents shouting "They are teaching my children to dispute the Bible!".

Face it.... coherent, logical thinking by any large % of the populace would seriously disrupt religious and political ends.

I think there is a message in the saying: "Never try to teach a pig to sing...it wastes your time and it annoys the pig!"
