This work adds to the theoretical development of the emerging fields of experiential learning and outdoor education by examining the central concept, 'experience', and interrogating a central claim of experiential learning: whether, and if so how, a short-term singular experience can transform a participant's life as a whole and in a permanent way. While such a possibility has been corroborated by the personal testimonies of participants, and the activities of instructors over many years, the book argues that we must go beyond this kind of 'evidence'.
