A classical Jungian developmental framework is utilised for these purposes. The paper begins with brief definitions of the concepts pertinent to this work followed by a fairly comprehensive summary of Neumann's developmental model. The author's model, constructed on this theoretical basis, is then outlined and applied at a mythological level to the attitudes to wilderness manifest in the Judaeo - Christian religions. In the discussion, indications are given as to how the model might be applied at individual and cultural levels. One person's experience of wilderness is interpreted within the context of the theory followed by a brief discussion on the use of the model in informing therapeutic wilderness programming. Traditional North American Indian and contemporary Western attitudes towards wilderness are then briefly interpreted. It is concluded that this paper illustrates the usefulness of a Jungian model in understanding wilderness experience. Within the context of this framework, the value of a developmental perspective is noted.
