One day, there was a blind man sitting on the steps of a building with a hat by his feet and a sign that read:

"I am blind, please help".

A creative publicist was walking by him and stopped to observe. He saw that the blind man had only a few coins in his hat. He dropped in a few more coins and, without asking for permission, took the sign, turned it around and wrote another announcement. He placed the sign by the blind man's feet and left.

That afternoon the creative publicist returned to where the blind man sat and noticed that his hat was full of bills and coins. The blind man recognized his footsteps and asked if it was he who had re-written his sign and he wanted to know what he had written on it.
The publicist responded: "Nothing that was not true, I just wrote your sign out a little differently." He smiled and went on his way.

The new sign read: "Today is Spring and I cannot see it."

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. Awaken him.

He who knows and knows that he knows is wise. Follow him.

Who really Knows??
