“One of the many things I learned at the end of that Classics corridor down which I ventured at the age of 18, in search of something I could not then define, was this, written by the Greek author Plutarch: What we achieve inwardly will change outer reality. That is an astonishing statement and yet proven a thousand times every day of our lives. It expresses, in part, our inescapable connection with the outside world, the fact that we touch other people’s lives simply by existing.”

“I hope that even if you remember not a single word of mine, you remember those of Seneca, another of those old Romans I met when I fled down the Classics corridor, in retreat from career ladders, in search of ancient wisdom:As is a tale, so is life: not how long it is, but how good it is, is what matters.”

“I have one last hope for you, which is something that I already had at 21. The friends with whom I sat on graduation day have been my friends for life. They are my children’s godparents, the people to whom I’ve been able to turn in times of trouble, friends who have been kind enough not to sue me when I’ve used their names for Death Eaters. At our graduation we were bound by enormous affection, by our shared experience of a time that could never come again, and, of course, by the knowledge that we held certain photographic evidence that would be exceptionally valuable if any of us ran for Prime Minister.”

“If you choose to use your status and influence to raise your voice on behalf of those who have no voice; if you choose to identify not only with the powerful, but with the powerless; if you retain the ability to imagine yourself into the lives of those who do not have your advantages, then it will not only be your proud families who celebrate your existence, but thousands and millions of people whose reality you have helped transform for the better. We do not need magic to change the world, we carry all the power we need inside ourselves already: we have the power to imagine better.”

“I can not remember telling my parents that I was studying classics, they might well have found out for the first time on graduation day. Of all the subjects on this planet, I think they would have been hard-put to name one less useful in Greek mythology when it came to securing the keys of an executive bathroom. Now I would like to make it clear in parenthesis, that I do not blame my parents for their point of view. There is an expiry date for blaming your parents for steering you in the wrong direction. The moment you are old enough to take the wheel, responsibility lies with you. What is more, I can not criticize my parents for hoping that I would never experience poverty. They had been poor themselves, and I have since been poor. And I quite agree with them, that it is not an ennobling experience. Poverty, entails fear, and stress, and sometimes depression, It means a thousand petty humiliations and hardships. Climbing out of poverty by your own efforts, that is something by which to pride yourself, but poverty itself, is romanticized only by fools. But I feared at your age was not poverty, but failure... Now, I am not dull enough to suppose that because you are young, gifted, and well educated, that you have never known heartbreak, hardship, or heartache. Talent and intelligence, never yet inoculated anyone against the caprice of the fates... ultimately, we all have to decide for ourselves what constitutes failure.”

“I am sorry too," said Lupin. "Sorry I will never know [my son]... but he will know why I died and I hope he will understand I was trying to make a world in which he could live a happier life.”

“First think of the person who lives in disguise,Who deals in secrets and tells naught but lies.Next, tell me what's always the last thing to mend,The middle of middle and the end of end?And finally give me the sound often heardDuring the search for a hard-to-find word.Now string them together, and answer me this,Which creature would you be unwilling to kiss?”
