Walt Whitman
“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

Bertrand Russell
“My desire and wish is that the things I start with should be so obvious that you wonder why I spend my time stating them. This is what I aim at because the point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.”
Bertrand Russell, The Philosophy of Logical Atomism

Carl Sagan
“The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what's true.”

Sam   Harris
“Tell a devout Christian that his wife is cheating on him, or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it. Tell him that the book he keeps by his bed was written by an invisible deity who will punish him with fire for eternity if he fails to accept its every incredible claim about the universe, and he seems to require no evidence what so ever.”
Sam Harris, The End of Faith: Religion, Terror, and the Future of Reason

Neil deGrasse Tyson
“One of the biggest problems with the world today is that we have large groups of people who will accept whatever they hear on the grapevine, just because it suits their worldview—not because it is actually true or because they have evidence to support it. The really striking thing is that it would not take much effort to establish validity in most of these cases… but people prefer reassurance to research.”
Neil deGrasse Tyson

Isaac Asimov
“Don't you believe in flying saucers, they ask me? Don't you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?
No, I reply. No, no, no, no, and again no.
One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"
Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.”
Isaac Asimov

Clarence Darrow
“I have always felt that doubt was the beginning of wisdom, and the fear of God was the end of wisdom.”
Clarence Darrow, The Story of My Life

Timothy J. Keller
“If Jesus rose from the dead, then you have to accept all that he said; if he didn't rise from the dead, then why worry about any of what he said? The issue on which everything hangs is not whether or not you like his teaching but whether or not he rose from the dead.”
Timothy J. Keller, The Reason for God: Belief in an Age of Skepticism

H.L. Mencken
“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

Criss Jami
“I'm convinced that most men don't know what they believe, rather, they only know what they wish to believe. How many people blame God for man's atrocities, but wouldn't dream of imprisoning a mother for her son's crime?”
Criss Jami, Killosophy

Criss Jami
“Friends ask you questions; enemies question you.”
Criss Jami, Healology

Jules Verne
“Reality provides us with facts so romantic that imagination itself could add nothing to them.”
Jules Verne

David Hume
“In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore, proportions his belief to the evidence.”
David Hume, An Enquiry Concerning Human Understanding
