“Even a wise man knows doubt from time to time, it is the fool who allows it to rule his judgement.”

“The fool who knows his folly Becomes wise by that fact.But the fool who thinks he's wise - He's called 'a fool' indeed!”

“We all are weak, in one way or another. It does not matter the species. Some times that weakness is a strength in dusguise. Sometimes it is our utter undoing. Some times it is both. A wise man seeks to find a lesson from it. A fool lets it control and destroy him.And sometimes the wise man is the fool.”

“Marshall Shafter...kept pasted in his desk drawer a piece of paper he looked at from time to time to remind himself of something. It said, "A fool can put on his own clothes better than wise man can do it for him.”

“I do not believe in any wise man until I have heard him say << I doubt it>> three times and << I don’t know >> two times.”

“The fool doth think he is wise, but the wise man knows himself to be a fool.”
