The Doctor

"Earl Sigma: You're a nice guy Doctor, but a little weird."

"Anybody remotely interesting is mad in some way."

"Among all the varied wonders of the universe, there's nothing so firmly clamped shut as the military mind."

"All is change, all is movement."

"There are worlds out there where the sky is burning, and the sea's asleep, and the rivers dream; people made of smoke and cities made of song. Somewhere there's danger, somewhere there's injustice, somewhere else the tea's getting cold. Come on, Ace. We've got work to do."

"I am not like you."

"Who am I? WHO — AM — I?"

"Grace, I came back to life before your eyes. I held back death. Look, I can't make your dream come true forever, but I can make it come true today."

"I love humans. Always seeing patterns in things that aren't there."

"Back of the ship....Because the front crashes first. Think it through."

"Have you ever thought what it's like to be wanderers in the Fourth Dimension? Have you? To be exiles?"
