“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.”
― Terry Goodkind, Wizard's First Rule

“no army has ever marched into battle thinking that the Creator had sided with their enemy.”
― Terry Goodkind, Wizard's First Rule

“... a mind needs books as a sword needs a whetstone, if it is to keep its edge.”
