Ditto everyone else's comments. This is a really good book. Readers should be aware that Irvine's goal of "persistent tranquility" isn't really what the Stoics had in mind; their objective was much more radical, in the same way that TED-talk "mindfulness" is a parboiled version of a much more radical Buddhism.

But still, a good intro.

There are other good Stoicism books, and anyone who's been through cognitive behavioral therapy will find Irvine's book a bit of a refresher course. Anyone have any comments about "Philosophy for Life" or "Stocism and the Art of Happiness"?
