This particular 10-year old post does a disservice to Prof. Devlin's work. I actually took his course on Mathematical Thinking and found it quite interesting, as was the book withe the same title I read several years ago. He is able to make certain concepts very clear, and I wish more profs had a similar attitude (many already do!). That said, I believe most people here already took a course on discrete mathematics including logic and so on, so I don't think it would be particularly interesting to HN audience.
