Setting: A very long book-signing queue

Dramatis personae:
Richard Dawkins (RD): A scientist. A public intellectual. A colossus among men.
Daniel Midgley (DM): A Daniel Midgley

Curtain rises.

DM: Hello again!
RD: (peers at DM as if for the first time, appears to recognise) Oh, hello.
DM: (hands over a copy of ‘The Magic of Reality’) This is the copy of your book that I read to my son.
RD: I’m glad! (Signs)
DM: Do you think that disgust was the mechanism for our evolved sense of morality?
RD: Yes. I do. (Hands back books)
DM: Thank you! (exit)
