Wizard’s First Rule
People are stupid.
Given proper motivation, almost anyone will believe almost anything. They will believe a lie because they want to believe it is true, or because they are afraid it might be true. Their heads are full of knowledge, facts and beliefs, and most of it is false, yet they think it all true. 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.
Zedd teaches this to Richard after Darken Rahl has already been using it. Give people an enemy, a purpose, a fear or a wish, and they will march. The old wizards made Confessors and Seekers precisely because of it: the truth, when it matters, has to be fought for.
