“If I were to wish for anything, I should not wish for wealth and power, but for the passionate sense of the potential, for the eye which, ever young and ardent, sees the possible. Pleasure disappoints, possibility never. And what wine is so sparkling, what so fragrant, what so intoxicating, as possibility!”

“Nothing is as heady as the wine of possibility”

“I am so fed up and joyless that not only have I nothing to fill my soul, I cannot even conceive of anything that could possibly satisfy it - alas, not even the bliss of heaven.”

“What I really lack is to be clear in my mind what I am to do, not what I am to know, except in so far as a certain knowledge must precede every action. The thing is to understand myself, to see what God really wishes me to do: the thing is to find a truth which is true for me, to find the idea for which I can live and die. ... I certainly do not deny that I still recognize an imperative of knowledge and that through it one can work upon men, but it must be taken up into my life, and that is what I now recognize as the most important thing.”

“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?”

“These words were spoken by Him to whom, according to His own statement, is given all power in heaven and on earth. You who hear me must consider within yourselves whether you will bow before his authority or not, accept and believe the words or not. But if you do not wish to do so, then for heaven's sake do not go and accept the words because they are clever or profound or wonderfully beautiful, for that is a mockery of God.”

“If I am capable of grasping God objectively, I do not believe, but precisely because I cannot do this I must believe. If I wish to preserve myself in faith I must constantly be intent upon holding fast the objective uncertainty so as to remain out upon the deep, over seventy thousand fathoms of water, still preserving my faith.”
