J.K. Rowling

Douglas Adams
“Now it is such a bizarrely improbable coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God.
The argument goes something like this: "I refuse to prove that I exist,'" says God, "for proof denies faith, and without faith I am nothing."
"But," says Man, "The Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED."
"Oh dear," says God, "I hadn't thought of that," and promptly vanishes in a puff of logic.
"Oh, that was easy," says Man, and for an encore goes on to prove that black is white and gets himself killed on the next zebra crossing.”
Douglas Adams, The Hitchhiker's Guide to the Galaxy

“For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable – what then?”
George Orwell, 1984

Douglas Adams
“There is no point in using the word 'impossible' to describe something that has clearly happened.”

Kristin Cashore
“It's not reasonable to love people who are only going to die," she said.
Nash thought about that for a moment, stroking Small's neck with great deliberation, as if the fate of the Dells depended on that smooth, careful movement.
"I have two responses to that," He said at last. "First, everyone is going to die. Second, love is stupid. It has nothing to do with reason. You love whomever you love. Against all reason I loved my father." He looked at her keenly. "Did you love yours?"
"Yes," she whispered.
He stroked Small's nose. "I love you," he said, "even knowing you'll never have me. And I love my brother, more than I ever realized before you came along. You can't help whom you love, Lady. Nor can you know what it's liable to cause you to do.”
Kristin Cashore, Fire

Clive James
“Common sense and a sense of humor are the same thing, moving at different speeds. A sense of humor is just common sense, dancing.”

“What does the brain matter compared with the heart?”
Virginia Woolf, Mrs. Dalloway

Anne Rice
“Consequently, if you believe God made Satan, you must realize that all Satan's power comes from God and so that Satan is simply God's child, and that we are God's children also. There are no children of Satan, really.”
Anne Rice, Interview with the Vampire

G.K. Chesterton
“Poets do not go mad; but chess-players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not, as will be seen, in any sense attacking logic: I only say that this danger does lie in logic, not in imagination.”
G.K. Chesterton, Orthodoxy

J.K. Rowling
“Which came first, the phoenix or the flame?”
"...I think the answer is that a circle has no beginning."
"Well reasoned.”
J.K. Rowling, Harry Potter and the Deathly Hallows

Albert Camus
“There are crimes of passion and crimes of logic. The boundary between them is not clearly defined.”
Albert Camus

René Descartes
“I suppose therefore that all things I see are illusions; I believe that nothing has ever existed of everything my lying memory tells me. I think I have no senses. I believe that body, shape, extension, motion, location are functions. What is there then that can be taken as true? Perhaps only this one thing, that nothing at all is certain.”
René Descartes

Deepak Chopra
“Mathematics expresses values that reflect the cosmos, including orderliness, balance, harmony, logic, and abstract beauty.”
Deepak Chopra

Richelle Mead
“How do you feel right now?"
"I hurt like hell."
"You'll feel worse tomorrow."
"So?"
"So, better get a jump on this while you still feel...not as bad."
"What kind of logic is that?" I retorted.”
Richelle Mead, Vampire Academy

Neil deGrasse Tyson
“I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.”
Neil deGrasse Tyson, The Sky Is Not the Limit: Adventures of an Urban Astrophysicist

René Descartes
“And thus, the actions of life often not allowing any delay, it is a truth very certain that, when it is not in our power to determine the most true opinions we ought to follow the most probable.”
René Descartes, Discourse on Method

George Carlin
“It turned out I was pretty good in science. But again, because of the small budget, in science class we couldn't afford to do experiments in order to prove theories. We just believed everything. Actually, I think that class was called Religion. Religion class was always an easy class. All you had to do was suspend the logic and reasoning you were being taught in all the other classes.”
George Carlin, Brain Droppings

Jonathan Swift
“It is useless to attempt to reason a man out of a thing he was never reasoned into.”
Jonathan Swift

Rowan Atkinson
“As hatred is defined as intense dislike, what is wrong with inciting intense dislike of a religion, if the activities or teachings of that religion are so outrageous, irrational or abusive of human rights that they deserve to be intensely disliked?”
Rowan Atkinson
