"I think the man had been shocked from normal good into complete evil. Now, when I say he was a good man, I don't mean that he hadn't had a bad thought, now and then. Or, that he hadn't committed ordinary transgressions against society. But, after all, that's the problem of civilized man's soul, isn't it? That good and evil are constantly fighting one another?"

"The world is yours, my darling, the moment is mine!"

"Ivy, my darling, you belong with the immortals. Come with me to Mount Olympus. Drink nectar with the gods. Sing the ancient songs of pleasure. And put Athena and Diana to shame."

"As you were leaving the room, you turned at the door, didn't you? And you said, "For a moment, I thought..." What did you think? What did you think? Did you think that Dr. Jekyll was falling in love with you? You, with your cheap little dreams? Or did you think, perhaps - that in him, you saw a bit of me, Hyde?"

"He ain't a man. He's a devil, he is. Why, he knows what you're thinkin' about, he does. Why, if he knows that I've been here today, I don't know what he'll do. It won't be nothin' human, I can tell you!"

"It's Hyde, sir. It's a man I know, Mr. Hyde. It's him that's done it and more. More I can't tell you. He ain't a human. He's a beast! And he won't let me go, sir, and I am afraid to run away."

"Here's hoping that Hyde rots - wherever he is. Burn slow when the time comes."

"It CHILLS you! Half-MAN! Half-MONSTER!"

"A Good Woman! A Bad Woman - who needed the love of both!"

"Let me put it this way: good and evil are so close as to be chained together in the soul. Now, suppose we could break that chain, separate those two selves - free the good in man, and let it go to its higher destiny and segregate the bad."
