Albus Dumbledore

"Justice requires both truth and mercy in equal measure."

"It is our choices that show what we truly are, far more than our abilities."

"Scars can come in handy. I have one myself above my left knee that is a perfect map of the London Underground."

"Fear of a name increases fear of the thing itself."

"It does not do to dwell on dreams and forget to live."

"I am not worried, Harry. I am with you."

"Happiness can be found even in the darkest of times, if one only remembers to turn on the light."

"To have been loved so deeply, even though the person who loved us is gone, will give us some protection forever."

"Understanding is the first step to acceptance, and only with acceptance can there be recovery."

"The truth is a beautiful and terrible thing, and should therefore be treated with caution."

"It takes a great deal of bravery to stand up to our enemies, but just as much to stand up to our friends."

"We are only as strong as we are united, as weak as we are divided."

"Do not pity the dead, Harry. Pity the living."

"It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived—in which case, you fail by default."

"The truth is like a lion; you don't have to defend it. Let it loose; it will defend itself."

"It matters not what someone is born, but what they grow up to be."

"Knowing yourself is the beginning of all wisdom."

"You will find that I will only truly have left this school when none here are loyal to me."

"It is our choices that make us who we are."

"The castle will protect those within it."

"There's no greater gift than the gift of time."

"Not all magic is light, and not all dark magic is evil."

"It is our duty to try to protect those who cannot protect themselves."

"The strongest connection we have is not one of flesh and blood, but of love and loyalty."

"Those who choose not to believe in magic will never find it."

"A wizard must never be left without hope."

"Knowledge is power, but wisdom is knowing how to use it."

"Time is something even the most powerful wizards cannot control."

"The best of us must sometimes eat crow."

"It is our choices that show what we truly are, far more than our abilities."
