African proverb

Knowledge is not the main thing, deeds are!

Benjamin Hoff (1946) - quote

Knowledge and experience does not necessarily speak the same language.

Confucius (551 BC-479 BC)

The essence of knowledge is, having it, to apply it; not having it, to confess your ignorance.

David Allen (1945 - )

It is possible to possess too much.  Man with a watch knows what the time is; man with two watches is never certain of the time.

David John Moore Cornwell (1931 - )

Information is not knowledge. Information is dead meat. And only God is able to transform information into knowledge (2008). (Moral: we should look for  knowledge, not information)

Galileo Galilei (1564 - 1642) - wisdom

You cannot teach anybody anything; you can only help him reach it (knowledge) alone.
