“Supposing there was no intelligence behind the universe, no creative mind. In that case, nobody designed my brain for the purpose of thinking. It is merely that when the atoms inside my skull happen, for physical or chemical reasons, to arrange themselves in a certain way, this gives me, as a by-product, the sensation I call thought. But, if so, how can I trust my own thinking to be true? It's like upsetting a milk jug and hoping that the way it splashes itself will give you a map of London. But if I can't trust my own thinking, of course I can't trust the arguments leading to Atheism, and therefore have no reason to be an Atheist, or anything else. Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God.”

“It seems to me immensely unlikely that mind is a mere by-product of matter. For if my mental processes are determined wholly by the motions of atoms in my brain I have no reason to suppose that my beliefs are true. They may be sound chemically, but that does not make them sound logically. And hence I have no reason for supposing my brain to be composed of atoms.”

“If the solar system was brought about by an accidental collision, then the appearance of organic life on this planet was also an accident, and the whole evolution of Man was an accident too. If so, then all our present thoughts are mere accidents--theaccidental by-product of the movement of atoms. And this holds for the thoughts of the materialists and astronomers as well as for anyone else's. But if their thoughts--i.e. of materialism and astronomy--are merely accidental by-products, why should we believe them to be true? I see no reason for believing that one accident should be able to give me a correct account of all the other accidents. It's like expecting that the accidental shape taken by the splash when you upset a milkjug should give you a correct account of how the jug was made and why it was upset.”

“If you were an atheist, Birbal," the Emperor challenged his first minister, "what would you say to the true believers of all the great religions of the world?" Birbal was a devout Brahmin from Trivikrampur, but he answered unhesitatingly, "I would say to them that in my opinion they were all atheists as well; I merely believe in one god less than each of them." "How so?" the Emperor asked. "All true believers have good reasons for disbelieving in every god except their own," said Birbal. "And so it is they who, between them, give me all the reasons for believing in none."-- From "The Shelter of the World”

“I never thought of it like that. I always thought of you as a part of me, like my own eyes or my own hands. You don't go around thinking 'I love my eyes, I love my hands', do you? But think what it would be like to live without your eyes or your hands. To be mad, or to be blind. I can't talk about it. It's how I feel.”

“Ginny!" said Mr. Weasley, flabbergasted. "Haven't I taught you anything? What have I always told you? Never trust anything that can think for itself if you can't see where it keeps its brain?”
