“Every mental act is composed of doubt and belief,but it is belief that is the positive, it is beliefthat sustains thought and holds the world together.”

“I have the courage, I believe, to doubt everything; I have the courage, I believe, to fight with everything; but I have not the courage to know anything; not the courage to possess, to own anything. Most people complain that the world is so prosaic, that life is not like romance, where opportunities are always so favorable. I complain that life is not like romance, where one had hard-hearted parents and nixies and trolls to fight, and enchanted princesses to free. What are all such enemies taken together, compared with the pale, bloodless, tenacious, nocturnal shapes with which I fight, and to whom I give life and substance?”

“Deep within every man there lies the dread of being alone in the world, forgotten by God, overlooked among the tremendous household of millions and millions.”

“All this is only fooling, for if it is true that every man must work for his own salvation, then all the prophecies about the future of the world are only valuable and allowable as a recreation, or a joke, like playing bowls or cards.”

“But doubt is wily and cunning and never, as it is sometimes said to be, loud or defiant. It is unassuming and sly, not bold or assertive - and the more unassuming, the more dangerous.”

“Above all, do not lose your desire to walk. Everyday, I walk myself into a state of well-being & walk away from every illness. I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it. But by sitting still, & the more one sits still, the closer one comes to feeling ill. Thus if one just keeps on walking, everything will be all right.”

“To defend something is always to discredit it. Let a man have a warehouse full of gold, let him be willing to give away a ducat to every one of the poor - but let him also be stupid enough to begin this charitable undertaking of his with a defence in which he offers three good reasons in justification; and it will almost come to the point of people finding it doubtful whether indeed he is doing something good. But now for Christianity. Yes, the person who defends that has never believed in it. If he does believe, then the enthusiasm of faith is not a defence, no, it is the assault and the victory; a believer is a victor.”
