This is from one of my favorite Fantasy Novel:
“人們是愚蠢的, 給予適當的動機, 幾乎每個人都會相信幾乎所有的東西。因為人是愚蠢的, 他們會相信一個謊言, 因為他們願意相信這是真的, 或者是因為他們害怕它可能是真的。人們的頭腦中充滿了知識, 事實和信念, 而大部份都是假的, 但他們認為這都是事實。人們是愚蠢的, 他們很少能分出謊言和真理, 但他們卻有信心他們可以, 所以都很容易被欺騙…“

“Wizard’s First Rule: people are stupid.” Richard and Kahlan frowned even more. “People are stupid; given proper motivation, almost anyone will believe almost anything. Because people are stupid, they will believe a lie because they want to believe it’s true, or because they are afraid it might be true. People’s heads are full of knowledge, facts, and beliefs, and most of it is false, yet they think it all true. People are stupid; they can only rarely tell the difference between a lie and the truth, and yet they are confident they can, and so are all the easier to fool.”
Because of Wizards First Rule, the old wizards created Confessors, and Seekers, as a means of helping find the truth, when the truth is important enough. Darken Rahl knows the Wizard’s Rules. He is using the first one. People need an enemy to feel a sense of purpose. It’s easy to lead people when they have a sense of purpose. Sense of purpose is more important by far than the truth. In fact, truth has no bearing in this. Darken Rahl is providing them with an enemy, other than himself, a sense of purpose. People are stupid; they want to believe, so they do.”
