- Most probably.

- And Karnak wasn't a particularly important deity, a third-rate god.

- Not to those who believed in him.

- Perhaps not. But their standard of intelligence must have been remarkably low.

- Why do you say that?

- He was insignificant. He had nothing to commend him to anyone with the slightest degree of intelligence.

- It occurred to me, but I dismissed it.

- You're intolerant, Mr Banning.

- Not intolerant, just practical.

- Intolerant.
