“If, then, I were asked for the most important advice I could give, that which I considered to be the most useful to the men of our century, I should simply say: in the name of God, stop a moment, cease your work, look around you.”

Letter I : Abelard To Philintus, as translated by John Hughes<!-- 1782 edition -->
Letters of Abelard and Heloise
Context: Sometimes I grieve for the house of the Paraclete, and wish to see it again. Ah, Philintus! does not the love of Heloise still burn in my heart? I have not yet triumphed over that happy passion. In the midst of my retirement I sigh, I weep, I pine, I speak the dear name of Heloise, pleased to hear the sound, I complain of the severity of Heaven. But, oh! let us not deceive ourselves: I have not made a right use of grace. I am thoroughly wretched. I have not yet torn from my heart deep roots which vice has planted in it. For if my conversion was sincere, how could I take a pleasure to relate my past follies? Could I not more easily comfort myself in my afflictions? Could I not turn to my advantage those words of God himself, If they have persecuted me, they will also persecute you; if the world hate you, ye know that it hated me also? Come Philintus, let us make a strong effort, turn our misfortunes to our advantage, make them meritorious, or at least wipe out our offences; let us receive, without murmuring, what comes from the hand of God, and let us not oppose our will to his. Adieu. I give you advice, which could I myself follow, I should be happy.

J. K. Rowling, as quoted in ‪Harry Potter's Bookshelf : The Great Books Behind the Hogwarts Adventures‬ (2009) by John Granger <!-- also partly in Biography Today : Profiles of People of Interest to Young Readers Vol. 17, Issue 1 (2008), p. 142 -->

Context: I think most of us if you were asked to name a very evil regime would think of Nazi Germany. … I wanted Harry to leave our world and find exactly the same problems in the Wizarding world. So you have to the intent to impose a hierarchy, you have bigotry, and this notion of purity, which is a great fallacy, but it crops up all over the world. People like to think themselves superior and that if they can pride themselves on nothing else, they can pride themselves on perceived purity. … The Potter books in general are a prolonged argument for tolerance, a prolonged plea for an end to bigotry, and I think it's one of the reasons that some people don't like the books, but I think that it's a very healthy message to pass on to younger people that you should question authority and you should not assume that the establishment or the press tells you all of the truth.
