Power of Persuasion

As a brief discussion on why the power of persuasion may be one of the greatest of all, the following excerpt from Phillip K. Dick is a well stated perspective:

"The basic tool for the manipulation of reality is the manipulation of words. If you can control the meaning of words, you can control the people who must use the words. George Orwell made this clear in his novel 1984. But another way to control the minds of people is to control their perceptions. If you can get them to see the world as you do, they will think as you do. Comprehension follows perception. How do you get them to see the reality you see? After all, it is only one reality out of many."
