“Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out.”

“The brain is like a muscle. When it is in use we feel very good. Understanding is joyous.”

“If you wish to make an apple pie from scratch, you must first invent the universe.”

“We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.”

“There are naive questions, tedious questions, ill-phrased questions, questions put after inadequate self-criticism. But every question is a cry to understand the world. There is no such thing as a dumb question.”

“The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.”

“A book is proof that humans are capable of working magic. It’s a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you’re inside the mind of another person, maybe somebody dead for thousands of years.”

“I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.”

“A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.”

“Imagination will often carry us to worlds that never were. But without it we go nowhere.”

“Science is a way of thinking much more than it is a body of knowledge.”

“For small creatures such as we the vastness is bearable only through love.”

“Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.”

“We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.”

“If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?”

“We've arranged a civilization in which most crucial elements profoundly depend on science and technology.”

“All of the books in the world contain no more information than is broadcast as video in a single large American city in a single year. Not all bits have equal value.”
