“I like the scientific spirit—the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine—it always keeps the way beyond open—always gives life, thought, affection, the whole man, a chance to try over again after a mistake—after a wrong guess.”
― Walt Whitman, Walt Whitman's Camden Conversations

“In all affairs it's a healthy thing now and then to hang a question mark on the things you have long taken for granted.”

― Tony Schwartz

“Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant, in this field as in all others. His culture is based on "I am not too sure.”
― H.L. Mencken

“The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.”

“My peak? Would I even have one? I hardly had had anything you could call a life. A few ripples. some rises and falls. But that's it. Almost nothing. Nothing born of nothing. I'd loved and been loved, but I had nothing to show. It was a singularly plain, featureless landscape. I felt like I was in a video game. A surrogate Pacman, crunching blindly through a labyrinth of dotted lines. The only certainty was my death.”
― Haruki Murakami, Dance Dance Dance

― Scott Westerfeld, Goliath

“...Granny Weatherwax, who had walked nightly without fear in the bandit-haunted forests of the mountains all her life in the certain knowledge that the darkness held nothing more terrible than she was...”
― Terry Pratchett

“We ought to regard the present state of the universe as the effect of its antecedent state and as the cause of the state that is to follow. An intelligence knowing all the forces acting in nature at a given instant, as well as the momentary positions of all things in the universe, would be able to comprehend in one single formula the motions of the largest bodies as well as the lightest atoms in the world, provided that its intellect were sufficiently powerful to subject all data to analysis; to it nothing would be uncertain, the future as well as the past would be present to its eyes. The perfection that the human mind has been able to give to astronomy affords but a feeble outline of such an intelligence.”
― Pierre Simon de Laplace

“The human spirit glows from that small inner light of doubt whether we are right, while those who believe with certainty that they possess the right are dark inside and darken the world outside with cruelty, pain, and injustice.”
― Saul Alinsky, Rules for Radicals: A Pragmatic Primer for Realistic Radicals

“He felt that he was still groping in the dark; he had chosen his path but kept looking back, wondering whether he had misread the signs, whether he should not have taken the other way.”
― J.K. Rowling, Harry Potter and the Deathly Hallows

“They say, "Look before you leap." So look. But do not look for too long. Do not look into the void of uncertainty trying to predict each and every possible outcome, to evaluate every possible mistake, to prevent each possible failure. Look for the opportunity to leap, and leap faster than your fear can grab you. Leap before you talk yourself out of it, before you convince yourself to set up a temporary camp that turns into a permanent delay on your journey into your own heart.”
― Vironika Tugaleva

“To better understand God we must first shatter our own idea of God - maybe even day after day. Maybe he's too great to stay compressed in the human mind. Maybe he splits it wide open; this is why pretentious intellectualism so often fails to comprehend the concept of God: it is only accepting of what it can explain while in the process finding higher sources offensive. What we may confidently assert is that faith is the opening that allows God, this unpredictable, unseen power, to travel in and out of the mind without all the pains of confusion.”
― Criss Jami, Killosophy

“Some make light of decisions, arguing that all possible decisions will occur. In such a world, how could one be responsible for his actions? Others hold that each decision must be considered and committed to, that without commitment there is chaos. Such people are content to live in contradictory worlds, so long as they know the reason for each.”
― Alan Lightman, Einstein’s Dreams

“Humans may crave absolute certainty; they may aspire to it; they may pretend, as partisans of certain religions do, to have attained it. But the history of science — by far the most successful claim to knowledge accessible to humans — teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us.”
― Carl Sagan, The Demon-Haunted World: Science as a Candle in the Dark

“Even then, she knew that there is no such thing as sure. There is no absolute anything. The gods love to fuck with us.”
