Ignorance

As I watch the talking heads, I can't help but recall a quotation:

"It ain't so much the things we don't know that get us into trouble.
It's the things we know that just ain't so."
[Aretmus Ward]

... and here's one more:

"Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity."
[Martin Luther King, Jr.]

... and just for fun:

"I feel that if a person has problems communicating the very least he can do is to shut up.
[Tom Lehrer]

Have a nice day.
