This anthology, first published in 2000, explores EL Education's roots in the educational philosophy of Kurt Hahn. Hahn, the founder of Outward Bound, started two schools and inspired many other educational initiatives. Roots includes an excellent essay on Hahn's educational thought, The Only Mountain Worth Climbing, by Thomas James, and the transcript of a speech on the educational contributions of Outward Bound, The Missing Dimension, by Paul Ylvisaker. This edition, published in 2021, includes a new foreword by Sydney Chaffee, a teacher at Codman Academy in Boston and the 2017 National Teacher of the Year.
