I had actually looked at older works without copyrights. Bacon's "New Atlantis" and Ignatius Donnely's "Atlantis the Ante-Deluvian World" have both been read aloud. I am considering Hakim Bey or Abbey Hoffman's "Steal This Book" at this point. I might also try Albert Pike's "Morals and Dogma" id my local AASR says that I can. They have the rights to his work, but I am a member and think Pike is very much misunderstood and under-read. Dude wrote about 200 books and was the first to translate many, many great works such as the Dhammapada. Epic warrior, philanthropist, lawyer, and Brother!
