DOCTOR: Think about me when you're living your life one day after another, all in a neat pattern. Think about the homeless traveller and his old police box, with his days like crazy paving.

ACE: Do you feel like arguing with a can of deodorant that registers nine on the Richter scale? Run!

BELAZS: What are you doing here?

DOCTOR: That's a very difficult question. Why is everyone round here so preoccupied with metaphysics?

ACE: Right, freeze! I mean, don't freeze. Stand still and let Mel go.

GUARD: Oh, you've no idea what a relief it is for me to have such a stimulating philosophical discussion. There are so few intellectuals about these days. Tell me, what do you think of the assertion that the semiotic thickness of a performed text varies according to the redundancy of auxiliary performance codes?

DOCTOR: Yes.

DOCTOR: Excuse me. What's your attitude towards the nature of existence? For example, do you hold any strong theological opinions?

GUARD: I think you'll find most educated people regard mythical convictions as fundamentally animistic.

DOCTOR: I see. That's a very interesting concept.

GUARD: Personally, I find most experiences border on the existential.

DOCTOR: Well, how do you reconcile that with the empirical critical belief that experience is at the root of all phenomena?

GUARD: I think you'll find that a concept can be philosophically valid even if theologically meaningless.

DOCTOR: So, what you're saying is that before Plato existed, someone had to have the idea of Plato.

GLITZ: This is the real McCoy, this is!
