I'm sure there has to be some 600-page book titled Calm: A Philosophical Inquiry, or something similar to scare of the casual reader, but so far I haven't found it. I can't imagine such a book hasn't been written; after all, there are tons of books about happiness, and excellent books about solitude, courage, etc., etc., and if I can see the need for it, someone else must have too (a world-view best summarized in this Wondermark cartoon).
