All knowledge is worth having. - Jacqueline Carey, Kushiel's Dart

"All knowledge is worth having."

"It is my observations, though, that happiness limits the amount of suffering one is willing to inflict upon others"

"Yes my lord, but questions are dangerous, for they have answers"

"This is the secret that none dares tell who fights for a cause. Dying, we are all alike."

"All knowledge is worth having."
