[Gen.Blather]

Most people think everything they know is everything there is to know. I’ve had managers who had competent people working for them and assumed that because the work was being well done that anybody could do it. Those are people who do not know what they do not know. That’s a special level of ignorance. Others feel that because they’re extremely competent on one subject, oral surgery, for example, that they are equally competent at everything else, piloting a plane for example. (More doctors are killed flying a plane than any other profession.)

Even pilots?

There are things that we know, then there are things we know we don't know and there are things that we don't know that we don't know, but there is always a liberal ready to explain it for us.

It isn’t that Liberals are ignorant. It’s just that they know so much that isn’t so.”
