I'm curious about the significance of the number thirteen in your work. I get the feeling that it is no coincidence that many of your books have thirteen chapters, end on page 413, and so on. Thirteen is an interesting number in many ways, and I have a few ideas as to why it might be significant. Still, I am curious to see what you might have to say in response to this. • Ishmael.org, the work & philosophy of Daniel Quinn
