The more primitive a person is, the easier it seems to him what surrounds him. The fool is always clear, he is always clear. Another opinion? Not the right. Another way of life? Not the normal. Others who are not similar to his hobbies? Irene, not worthy of attention. The fool is not only absolutely confident in the high level of his intelligence and the infallibility of his knowledge, but also rushes to teach others. He probably wants the others to be like him.
