Even though people are different, they all share the knowledge of common conduct. Give a detail instruction of how to make a gun, and thousands will make it identicaly. May be there will be one fool, who won't get the instruction. He is just too 'unsimilar' to get it. His understanding of the world is so personal, that even clear cut frase can sense for him differently. His vision...... If he finds out how to 'show' others his vision and explain why its wonderful, people will call him a genie, if not he would remain a fool.....

So if you are fool yet, just keep it silent.
