If you can control a man's thinking, you do not have to worry about his actions. When you determine what a man shall think you do not have to concern yourself about what he will do. If you make a man feel that he is inferior, you do not have to compel him to accept an inferior status, for he will seek it himself . If you make a man think that he is justly an outcast, you do not have to order him to the back door. He will go without being told; and if there is no back door, his very nature will demand one.
Many men absorbed in business show such a rare quality of culture that we are surprised at it. The reason invariably is partly because hard work and even the weariness it leaves carry a nobility with them, but also because there is no room in such lives for inferior mental occupation.
It was said that the 'brutes' cannot reason. Only persons who do not themselves reason about the subject, with the facts before them, can any longer occupy such a position.

The nobler sort of man emphasizes the good qualities in others, and does not accentuate the bad. The inferior does the reverse. . . . The nobler sort of man pays special attention to nine points. He is anxious to see clearly, to hear distinctly, to be kindly in his looks, respectful in his demeanor, conscientious in his speech, earnest in his affairs. When in doubt, he is careful to inquire; when in anger, he thinks of the consequences; when offered an opportunity for gain, he thinks only of his duty.
