Albus Dumbledore

"The greatest power is love, not darkness."

"The past cannot be changed."

"Friendship is a gift, not a right."

"Prejudice is the mark of a weak mind."

"The innocent do not perish in the dark."

"The right choice is rarely the easy one."

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

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

"Time is a precious thing. Don't waste it."

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

"Even miracles take a little time."

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

"Curiosity is not a sin, but we should exercise caution with it."

"Believe me, I would not ask it if I did not have to."

"Unless they've found another way in, which I doubt."

"One can never have enough socks. Another Christmas has come and gone and I didn't get a single pair."

"This is a crime of passion, not the dark arts."

"Extraordinary things happen in this school."

"The knowledge that you have tried everything and failed can be a burden."

"Some mysteries are worth the solving."

"Help will always be given at Hogwarts to those who ask for it."

"Some people deserve a second chance."

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

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

"The consequences of our actions are always so complicated, so diverse, that predicting the future is a very difficult business indeed."

"Harry, suffering like this proves you are still a man! This pain is part of being human."

"To the well-organized mind, death is but the next great adventure."

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

"You fail to recognize that it matters not what someone is born, but what they grow to be."

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