Lies and Deceit Quotes in The Curious Incident of the Dog in the Night-Time

How we cite our quotes:

Quote #4

This makes you wonder what he was called before he carried Christ across the river. But he wasn't called anything because this is an apocryphal story which means that it is a lie, too. (29.9)

And what about this one? Does Christopher really consider all stories to be lies? He's already established how much he dislikes lying in general, but what about the stories he likes, like Sherlock Holmes? Are those lies too? Or are those okay?

Quote #5

I do not tell lies. Mother used to say that this was because I was a good person. But it is not because I am a good person. It is because I can't tell lies. (37.1)

Lying and not lying aside, what do you think: is Christopher a good person?

Quote #6

A lie is when you say something happened with didn't happen. But there is only ever one thing which happened at a particular time and a particular place. And there are an infinite number of things which didn't happen at that time and that place. And if I think about something which didn't happen I start thinking about all the other things which didn't happen. (37.2)

Is that really the only possible way to lie? What about saying something didn't happen that really did? Can you think of a reason why Christopher wouldn't be as concerned with that side of lying?
