It takes much bravery to stand up to our enemies but we need as much bravery to stand up to our friends.
It is our choices, Harry, that show us who we truly are, far more than our abilities.
Do not pity the dead, Harry. Pity the living, and, above all those who live without love.
It does not do to dwell on dreams and forget to live.
You place too much importance, and you always have done, on the so-called purity of blood! You fail to recognize that it matters not what someone is born, but what they grow to be!
"The truth." Dumbledore sighed. "It is a beautiful and terrible thing, and therefore should be treated with caution..."
It is my belief that the truth is generally preferable to lies.
Humans do have a knack for choosing precisely those things which are worst for them.
It is a curious thing, Harry, but perhaps those who are best suited to power are those who have never sought it.
To the well-organised mind, death is but the next great adventure.
