Harry Potter and the Half-Blood Prince

"Horace is a collector of the talented."

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

"Dumbledore says he will set store by nothing I say, because I am no Occlumencer."

"I have always found that the wisest people bestow the most admiration on those who surpass them."

"The truth is a beautiful and terrible thing."

"It is a curious thing, is it not, how much more we trust the senses of a dog than we do a human mind."

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

"Draco Malfoy is not mad. He is simply a boy who has been given a task he does not wish to perform."

"Greatness inspires envy, envy engenders hate, hate engenders conflict."

"There is no greatness without goodness."

"I am not interested in your opinions, you silly boy."

"It is not our abilities that show what we truly are, it is our choices."

"Dumbledore says people find it far easier to forgive others for being wrong than being right."

"The boy who lived will die."

"He can run, but he cannot hide."

"Dark and difficult times lie ahead. Soon we must all face the choice between what is right and what is easy."

"Voldemort himself created his worst enemy, just as tyrants always do."

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

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

"It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived."

"We've all got both light and dark inside us. What matters is the part we choose to act on."

"Do not pity the dead, Harry. Pity the living, and above all, those who live without love."

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

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

"Dark and difficult times lie ahead. Soon we must all face the choice between what is right and what is easy."

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

"Voldemort likes to compartmentalize."

"It is impossible to manufacture or imitate love."

"It is strange how little we know about the people we work with."

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