John Seymour, author of the manifesto, is the doyen of the British smallholder movement (US: read "homesteading" or "back-to-the-land"). John and his ex-wife Sally were "homesteaders" in England at a time when "self-sufficient" living was incomprehensible crankery to the mainstream. His books (e.g.) are witty, entertaining, and instructive. He has not dimmed with age; at 84 he was arrested and tried for partially destroying a field of GMO sugar beets in an act of civil disobedience.
