When you publish a book, you need to do publicity for the book. That consists largely of hoping to get the opportunity to talk about your book on the media. It’s a bit of a paradoxical situation, because you’re half inclined to say “well if you would just read the book, then you’d know the answer.” But of course that’s not how it’s done. You answer the question, you talk a bit, and you hope people get interested in the book. At least, that’s how most people do it. Then there’s John McCain talking to Time:

There’s a theme that recurs in your books and your speeches, both about putting country first but also about honor. I wonder if you could define honor for us?
Read it in my books.

I’ve read your books.
No, I’m not going to define it.

But honor in politics?
I defined it in five books. Read my books.

So in case you’re wondering about the central theme of McCain’s presidential campaign, well, you’d better read his books I guess. I wonder what would have happened if they’d asked him a difficult question like what does he mean when he talks about “victory” in Iraq.
