"All fanaticism is repressed doubt...." - Quote by Carl Jung

“A dream that is not understood remains a mere occurrence; understood it becomes a living experience.”

“We need more understanding of human nature, because the only real danger that exists is man himself.”

“The debt we owe to the play of imagination is incalculable.”

“Since opposed principles, or ideologies, are irreconcilable, wars fought over principle will be wars of mutual annihilation. But wars fought for simple greed will be far less destructive, because the aggressor will be careful not to destroy what he is fighting to capture. Reasonable - that is, human - men will always be capable of compromise, but men who have dehumanized themselves by becoming the blind worshipers of an idea or an ideal are fanatics whose devotion to abstractions makes them the enemies of life.”

“One defeats a fanatic precisely by not being a fanatic oneself, but on the contrary by using one's intelligence.”

“The worst vice of the fanatic is his sincerity.”

“Until I know this sure uncertainty, I'll entertain the offered fallacy.”

“The more he became truly wise, the more he distrusted everything he knew.”

“Think'st thou I'd make a life of jealousy, To follow still the changes of the moon With fresh suspicions? No; to be once in doubt Is once to be resolved.”
