“Wands are only as powerful as the wizards who use them. Some wizards just like to boast that theirs are bigger and better than other people's.”
“It's not the wand, it's the wizard.”
“A man's magic demonstrates what sort of person he is, what is held most deeply inside of him. There is no truer gauge of a man's character than the way in which he employs his strength, his power. I was not a murderer. I was not like Victor Sells. I was Harry Blackstone Copperfield Dresden. I was a wizard. Wizards control their power. They don't let it control them. And wizards don't use magic to kill people. They use it to discover, to protect, to mend, to help. Not to destroy.”
“Don't put your wand there, boy! What if it ignited? Better wizards than you have lost buttocks, you know.""Who d'you know who's lost a buttock?""Never you mind...”
“Some people think this is paranoia, but it isn't. Paranoids only think everyone is out to get them. Wizards know it.”
“No wizard has ever made himself useful by magic, or, if they've tried, they've only made matters worse. No wizard ever stopped a war or mended a fence. It's better that they stay in their marshes, out of the way of worldly folk like farmers and soldiers and merchants and kings.”
