“To doubt is better, because it helps understand, aids searching. Question is everything, answer is maturity.”

“Nobody likes to see a body, but it's better than seeing a ghost. Bodies just make you doubt the world and the people in it. Ghosts make you doubt everything, and to doubt it in a part of the mind that has no words to answer the question, where the comforting promises you make yourself are neither believed nor even really understood.”

“"What is the meaning of life?" This question has no answer except in the history of how it came to be asked. There is no answer because words have meaning, not life or persons or the universe itself. Our search for certainty rests in our attempts at understanding the history of all individual selves and all civilizations. Beyond that, there is only awe.”

“Scepticism is not irrefutable, but obviously nonsensical, when it tries to raise doubts where no questions can be asked.
For doubt can exist only where a question exists, a question only where an answer exists, and an answer only where something can be said.”

“Why is doubt the one thing we're never skeptical of? We question other peoples' beliefs, and the more sure they are the more we doubt them. But it never occurs to us to doubt our own doubt. Question our own questions. We think our questions are answers.”

“People will continue to search for answers to universal and perplexing problems. But to find meaningful answers, one must first know what questions to ask.”

“Question everything. Learn something. Answer nothing.”

“Successful people ask better questions, and as a result, they get better answers.”

“I was a narrative historian, believing more and more as I matured that the first function of the historian was to answer the child's question, "What happened next?"”

“The new world will be a place of answers and no questions, because the only questions left will be answered by computers, because only computers will know what to ask.”
