My background is in Analytic Philosophy, so I'm fairly familiar with Dennett. His rise to prominence during the early 2000's seemed appropriate given the huge shift in American religious belief. Though, I still certainly understand that folks can be exasperated by that movement, I just don't think that you can experience a 30% drop in religious affiliation, in a single generation, without annoying people.[1]
I read his book Breaking the Spell: Religion as a Natural Phenomenon, which I found really interesting in that I'd never thought about religion as a concept being an evolutionary adaptive (or "hijacking") feature. I found it fascinating, though not profound. That said, I think some of the best philosophical work is just that. Really insightful ideas that make perfect sense once you think about them, you just probably wouldn't take the time to think about them.
