There’s strong men of wisdom in many different fields. They say 5% of the people are wise and righteous and 10% are wise but use their wiseness for wickedness or to deceive others. It’s like a magician: he knows the answer to the trick, but you don’t. He has to keep you blind to the truth in order for the illusion to work. When you’ve got that kind of wisdom and somebody else doesn’t, you can always take advantage of them.
