The last of three very interesting books by Dan Calabrese. I read the 2013 revised edition which was supposed to have the foul language removed, but once again (as with the other two books) for some reason they didn't quite remove it all. There's still occasional foul language in the book and that's really my only complaint with these books. I would prefer that all of the foul language be removed. Other than that this another fascinating book from Dan Calabrese, although my favorite of the three is "Pharmakeia".
