“They Harry Potters still enormously outnumber the likes of Petunia and Vernon Dursley in society, who just don't hold with such nonsense, perhaps reflecting how modern life seems more out of control than ever. Most people do indeed believe in magic of one sort or another, whether the thespian who shouts "break a leg" at a colleague, the student who always wears the same outfit for exams, the blushing bride who crosses her fingers for good luck or those who jump with joy when they find a four-leaf clover. Why is our belief in magic so deeply ingrained? Indeed, why do we believe in anything at all?”

“If Newton had not, as Wordsworth put it, voyaged through strange seas of thought alone, someone else would have. If Marie Curie had not lived, we still would have discovered the radioactive elements polonium and radium. But if J. K. Rowling had not been born, we would never have known about Harry Potter. That is why Master Potter means so much to me. Science may be special but Harry, as a work of art, is more so. Harry Potter is unique.”

“Words can calm people, can make them them fall in love, can whip them up into a frenzy, can turn them into killers.”

“Those who don't believe in magic will never find it.”

“there is no greater fool than one who believes his own lies.”

“Do not keep company with people who speak of careers. Not only are such people uninteresting in themselves; they also have no interest in anything interesting. . . . Keep company with people who are interested in the world outside themselves. The one who never asks you what you are working on; who never inquires as to the success of your latest project; who never uses the word career as a noun -- he is your friend.”

“The nonbelievers need the believers. They are desperate to have someone believe." "As belief shrinks from the world, people find it more necessary than ever that someone believe... Those who have abandoned belief must still believe in us. They are sure that they are right not to believe but they know belief must not fade completely. Hell is when no one believes.”
