"... I'd be interested to see a list of all the 46 passages though ..."

There is more than 46 (725) ~ http://www.google.com/search?q=site%3Ahttp%3A%2F%2Fpaulgraha... If there is a pattern, could it be emerging from "asking questions", thinking, then finding non-obvious or surprising results? Reading through the authors site I found this gem also another explanation.

"... If one is convinced that mind is a computer program, or at least if one thinks of that as a fruitful metaphor, it may be helpful to think about these “thought-generating phrases” as function calls. They are like little labels that execute a useful module, or packaged set of computational instructions. And the point is, just having a label makes it easier to find the code, and therefore more likely that you’ll execute it. Which is exactly what you want if the code is worth calling. ..." ~ http://jsomers.net/blog/generating-thoughts

It quite possible the phrase, "it turns out" is also a thought generating phrase.
