“The trouble is, humans do have a knack of choosing precisely those things that are worst for them.”

“As much money and life as you could want! The two things most human beings would choose above all - the trouble is, humans do have a knack of choosing precisely those things that are worst for them.”

“Is 'fat' really the worst thing a human being can be? Is 'fat' worse than 'vindictive', 'jealous', 'shallow', 'vain', 'boring' or 'cruel'? Not to me.”

“If you choose to use your status and influence to raise your voice on behalf of those who have no voice; if you choose to identify not only with the powerful, but with the powerless; if you retain the ability to imagine yourself into the lives of those who do not have your advantages, then it will not only be your proud families who celebrate your existence, but thousands and millions of people whose reality you have helped transform for the better. We do not need magic to change the world, we carry all the power we need inside ourselves already: we have the power to imagine better.”

“It is a curious thing, Harry, but perhaps those who are best suited to power are those who have never sought it. Those who, like you, have leadership thrust upon them, and take up the mantle because they must, and find to their own surprise that they wear it well.”

“Unlike any other creature on this planet, human beings can learn and understand without having experienced. They can think themselves into other peoples’ places. Of course, this is a power like my brand of fictional magic that is morally neutral. One might use such a power to manipulate or control, just as much as to understand or sympathize. And many prefer not to exercise their imaginations at all. They choose to remain comfortably within the bounds of their own experience, never troubling to wonder how it would feel to have been born other than they are. They can refuse to hear screams or peer inside cages. They can close their hearts and minds to any suffering that does not touch them personally. They can refuse to know. I might be tempted to envy people who can live that way, except that I do not think that they have any fewer nightmares than I do.”

“Voldemort himself created his worst enemy, just as tyrants everywhere do! Have you any idea how much tyrants fear the people they oppress? All of them realize that, one day, amongst their many victims, there is sure to be one who rises against them and strikes back!”
