“Belief can be manipulated. Only knowledge is dangerous.”

“When it comes to controlling human beings there is no better instrument than lies. Because, you see, humans live by beliefs. And beliefs can be manipulated. The power to manipulate beliefs is the only thing that counts.”

“Manipulation is an art, but it is a double-edged knife and can be a dangerous weapon in the wrong hands.”

“The only thing more dangerous than an idea is a belief.”

“The danger arises when a culture takes its own story as the absolute truth, and seeks to impose this truth on others as the yardstick of all knowledge and belief.”

“There can be knowledge of the diabolical, but no belief in it, for more of the diabolical than there is does not exist.”

“The only thing more dangerous than an idea is a belief. And by dangerous I don't mean thought-provoking. I mean: might get people killed.”

“Are you Earthseed?
Do you believe?
Belief will not save you.
Only actions
Guided and shaped
By belief and knowledge
Will save you.
Belief
Initiates and guides action—
Or it does nothing.”

“Knowledge is something which you can use.
Belief is something which uses you.”

“Knowledge in and of itself is devoid of good and evil. Knowledge, however, does not necessarily make human beings wiser. In fact, knowledge without wisdom can be outright dangerous.”
