"There will be no foolish wand-waving or silly incantations in this class. As such, I don’t expect many of you to appreciate the subtle science and exact art that is potion-making. However, for those select few…who possess, the predisposition… I can teach you how to bewitch the mind and ensnare the senses. I can tell you how to bottle fame, brew glory, and even put a stopper in death. Then again, maybe some of you have come to Hogwarts in possession of abilities so formidable that you feel confident enough to not pay attention. "

— Snape, " Harry Potter and the philosopher’s stone"
