Keeble is the founder of Golgonooza Press where he worked as editor, designer and publisher from 1974-2004.
He was a co-founder and is a Fellow of the Temenos Academy - whose Patron is Charles, Prince of Wales - which is a teaching organization dedicated to the same central idea that had inspired the earlier Temenos, of which he was a co-founder and editor (1980–1991). Both focus on a devotion to the ‘Arts of the Imagination’ and feature the lectures and works of scholars and teachers committed to Perennial Philosophy.
