Knowledge is a very powerful tool. It is very effectively used to control people. Women have historically been denied the right to an education to ensure that they are dependent on men. The same applies to African Americans before the civil rights movement.
The more knowledgeable someone is than you, the more control they can have over you. A frightening but remarkable aspect of knowledge is that the ill informed individuals will not even realize that their lives are systematically controlled because they do not know what they do not know . They do not know what they should know .
More and more of us are blindly accepting what is told to us. We rarely inquire about sources and alternatives. We are a society with the most amount of information available to us right at our fingertips, very literally, yet we rarely verify what we have always believed.
We are in a trance of consumerism and materialism.
