The Stoic Handbook
Erik Wiegardt is the founder of the Stoic College and New Stoa. His handbook is an excellent introduction to the ancient philosophy of Stoicism, which we often cover in the Society, due to its highly useful content for naturalists. He has given the Society special permission to include his handbook into our growing spiritual naturalist educational archive!
