The listed Wizard Rules from the "Sword of Truth" Series by Terry Goodkind:

Wizard's First Rule: People are stupid.
"People can be made to believe any lie, either because they want it to be true or because they fear that it is.

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. People want to believe, so they do."

 

Wizard's Second Rule: The greatest harm can result from the best intentions.
Even if you have the greatest of intentions in mind while doing something, the outcome can still be unpredictable and deadly. The greatest harm can result from the best intentions. It sounds a paradox, but kindness and good intentions can be an insidious path to destruction. Sometimes doing what seems right is wrong, and can cause harm. The only counter to it is knowledge, wisdom, forethought, and understanding the First Rule. Even then, that is not always enough.

Wizard's Third Rule: Passion rules reason.
People will let their feelings get in place of what is right or wrong.

Wizard's Fourth Rule: There is magic in sincere forgiveness.
In the forgiveness you grant, and more so in the forgiveness you receive ... magic to heal.


Wizard's Fifth Rule: Mind what people do, not only what they say, for deeds will betray a lie.
"Mind what people do, not only what they say, for deeds will betray a lie."

Wizard's Sixth Rule: "...the only sovereign you can allow to rule you is reason."
The first law of reason states that what exists exists, what is is. And from this irreducible bedrock principle all knowledge is gained.

 

Wizard's Seventh Rule: Life is the future, not the past.
The past can teach us, through experience, how to accomplish things in the future, comfort us with cherished memories, and provide the foundation of what has already been accomplished. But only the future holds life. To live in the past is to embrace what is dead. To live life to its fullest, each day must be created anew.

Wizard's Eighth Rule: "Deserve Victory"
