It is what we learn after we think we know it all that counts.

Never get mad at one who knows more than you do.  It's not his fault, but yours.

The next best thing to knowing a fact is knowing where to find it.

The person who knows everything has a lot to learn.

Knowledge puffs up.  Love builds up.

Wise men know more than they tell.  Fools tell more than they know.

Be sure of your facts or be prepared for disappointment.

Facts are stubborn things, but properly used, they will work hard for you.

A dogmatic person always has concrete opinions thoroughly mixed and permanently set.

Be careful of the theories on which you bias your opinions.

Make sure you know the difference between a fact and something that is based firmly on supposition or false logic.

An investment in knowledge always pays excellent interest.
