ROMANA: Oh, I do love the spring. All the leaves, the colours.

DOCTOR: It's October.

ROMANA: I thought that you said we were coming here for May week.

DOCTOR: I did. May week's in June.

ROMANA: I'm confused.

DOCTOR: So was the TARDIS.

ROMANA: Oh, I do love the autumn. All the leaves, the colours.

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: Winning? Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because, because I want to blame someone. It's not because it's fun and God knows it's not because it's easy. It's not even because it works, because it hardly ever does. I do what I do, because it's right! Because it's decent! And above all, it's kind. It's just that. Just kind. If I run away today, good people will die. If I stand and fight, some of them might live. Maybe not many, maybe not for long. Hey, you know, maybe there's no point in any of this at all, but it's the best I can do, so I'm going to do it. And I will stand here doing it till it kills me. You're going to die too, some day. How will that be? Have you thought about it? What would you die for? Who I am is where I stand. Where I stand, is where I fall. Stand with me. These people are terrified. Maybe we can help, a little. Why not, just at the end, just 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.

SKAGRA: Take over the universe? How childish. Who could possibly want to take over the universe?

DOCTOR: Exactly. That's what I keep telling people. It's a troublesome place, difficult to administer. And as a piece of real estate, it's worthless, because by definition there'd be no one to sell it to.

DOCTOR: Of course we should interfere. Always do what you’re best at, that’s what I say.

DOCTOR: The very powerful and the very stupid have one thing in common. They don’t alter their views to fit the facts, they alter the facts to fit their views. Which can be uncomfortable if you happen to be one of the facts that needs altering.
