DOCTOR: Okay. Name - the Doctor. Occupation - not a doctor. Current status - just passing by. Employer - myself. Address - that blue box over there. Now, if you don't mind, I just got snowmanned, and I would like to go home.

DOCTOR: It's funny, cos I wonder where the TARDIS goes at random. Maybe it lands on some outcrop by the sea. And there's a tribe and they worship it for 100 years. Then they grow up and try to burn it. Then they get wise. They preserve it. Then they build a city all around it, till the TARDIS is just a tiny little dot, surrounded by skyscrapers and monorails. Time passes and the city falls. It all gets swept away. And there's the TARDIS… still on its outcrop… by the sea. She's the only thing I've got left.

RUTH: (To the Thirteenth Doctor) Have you ever been limited by who you were before?

DOCTOR: Cos sometimes this team structure isn't flat. It's mountainous, with me at the summit in the stratosphere, alone, left to choose.

DOCTOR: Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.

DOCTOR: Without hope. Without witness. Without reward.

DOCTOR: Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.

DOCTOR: As you come into this world, something else is also born. You begin your life, and it begins a journey towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow. Never faster, never slower, always coming. You will run. It will walk. You will rest. It will not. One day, you will linger in the same place too long. You will sit too still or sleep too deep, and when, too late, you rise to go, you will notice a second shadow next to yours. Your life will then be over.

WAR DOCTOR: Great men are forged in fire. It is the privilege of lesser men to light the flame, whatever the cost.

DOCTOR: I'm not running away. But this is one corner of one country in one continent on one planet that's a corner of a galaxy that's a corner of a universe that is forever growing and shrinking and creating and destroying and never remaining the same for a single millisecond. And there is so much, so much to see, Amy. Because it goes so fast. I'm not running away from things, I am running to them before they flare and fade forever. And it's all right. Our lives won't run the same. They can't. One day, soon maybe, you'll stop. I've known for a while.

DOCTOR: We’re all stories, in the end. Just make it a good one, eh?

DOCTOR: There was a war. A Time War. The last Great Time War. My people fought a race called the Daleks, for the sake of all creation. And they lost. They lost. Everyone lost. They're all gone now. My family, my friends, even that sky. Oh, you should have seen it, that old planet. The second sun would rise in the south, and the mountains would shine. The leaves on the trees were silver, and when they caught the light every morning, it looked like a forest on fire. When the autumn came, the breeze would blow through the branches like a song.

DOCTOR: Your race is dead! You all burnt, all of you. Ten million ships on fire. The entire Dalek race wiped out in one second.

DALEK: You lie!

DOCTOR: I watched it happen. I made it happen.

DOCTOR: I tolerate this century, but I don't enjoy it. Have you ever thought what it's like to be wanderers in the fourth dimension? Have you? To be exiles? Susan and I are cut off from our own planet, without friends or protection. But one day we shall get back. Yes, one day. One day.
