On December 18 at 7 p.m., Brayton Shanley will speak about his 25 years of living off the land, building a straw bale house and running a “grease” car all while working in the community to build a more peaceful and responsible world. Sustainability is a word held dear by Shanley. His new book, taken from his essays in Servant Song, is entitled The Many Sides of Peace: Christian Nonviolence, the Contemplative Life, and Sustainable Living.
