A Variation from a Mailing List

Four Type of Doctors
He who knows, and knows he knows,
will give you good care but be arrogant.

He who knows, and does not know he knows,
will give you good care and be humble.

He who does not know, and knows he does not know,
will give you good care, often asking for help when he needs it.

He who does not know, and does not know he does not know,
will kill you.

A Persian Proverb

He who knows not,
And knows not that he knows not,
Is a fool - shun him.

He who knows not,
And knows that he knows not,
Is a child - teach him.

He who knows,
And knows not that he knows,
Is asleep - wake him.

He who knows,
And knows that he knows,
Is wise - follow him.

Kay: 1500 years ago, everybody "knew" that the earth was the center of the universe. 500 years ago, everybody "knew" that the earth was flat. And 15 minutes ago, you "knew" that humans were alone on this planet. Imagine what you'll "know" tomorrow.
