The person who knows everything has the most to learn.
The less a man knows, the easier it is to convince him he knows it all.
Nothing annoys me more than a man who thinks he knows it all and does.
Feel sorry for the man who has been educated beyond his intelligence.
The only successful substitute for a lack of brain is silence.
The more a man knows himself, the less he says about it.
A wise man never blows his knows.
If a little learning is a dangerous thing, then most people are safe.
Knowing a lot is of no value if what you know isn’t so.
An ignorant person is one who doesn’t know what you just found out.
