It is often suggested that when
writing fiction you don’t want to tell your audience the answer is 4, you want
to put 2 and 2 in front of them and let them work it out.
This is a powerful way of getting
them involved in the story. If they’re putting things together in their head
then they’re participating in the narrative, which is what you want.
But the way logic works once people
are involved is not always the same as it works in mathematics.
Sometimes 2+2=5, and when you put
that in front of your audience they will want to know what the hell you mean
and demand an explanation. And there’s nobody more involved than someone
wanting answers.
