J.K. Rowling, Harry Potter and the Sorcerer's Stone

"It does not do to dwell on dreams and forget to live."

"As much money and life as you could want! The two things most human beings would choose above all - the trouble is, humans do have a knack of choosing precisely those things that are worst for them."

"Alas! Earwax!"

"Call him Voldemort, Harry. Always use the proper name for things. Fear of a name increases fear of the thing itself."

"So light a fire!"Harry choked. "Yes...of course...but there's no wood!"... "HAVE YOU GONE MAD!"Ron bellowed. "ARE YOU A WITCH OR NOT!"

"There is no good and evil, there is only power and those too weak to seek it."

"Do you mean ter tell me,"he growled at the Dursleys, "that this boy—this boy!—knows nothin' abou'—about ANYTHING?"Harry thought this was going a bit far. He had been to school, after all, and his marks weren't bad."I know some things,"he said. "I can, you know, do math and stuff."

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

"There is no good and evil, there is only power and those too weak to seek it."

"He didn't realize that love as powerful as your mother's for you leaves its own mark."

"They heard the click of the mail slot and flop of letters on the doormat. "Get the mail, Dudley,"said Uncle Vernon from behind his paper. "Make Harry get it.""Get the mail, Harry.""Make Dudley get it.""Poke him with your Smelting stick, Dudley."

"What happened down in the dungeons between you and Professor Quirrell is a complete secret, so, naturally the whole school knows."

"Ah, music,"he said, wiping his eyes. "A magic beyond all we do here!"

"I hope you're pleased with yourselves. We could all have been killed - or worse, expelled. Now if you don't mind, I'm going to bed."

"You haven't got a letter on yours,"George observed. "I suppose she thinks you don't forget your name. But we're not stupid-we know we're called Gred and Forge."

"Nitwit! Blubber! Oddment! Tweak!"

"Everybody finished the song at different times. At last, only the Weasley twins were left singing along to a very slow funeral march."

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

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

"There are some things you can't share without ending up liking each other, and knocking out a twelve-foot mountain troll is one of them."
