Antoine Faivre and Christine Rhone (2010) develop a general taxonomy of Western esotericism in their short text Western Esotericism: A Concise History. Their designations are extremely helpful for the new student seeking to understand the ideas, concepts and challenges presented in the study of esotericism, for the very reasons Faivre and Rhone point out. Because the term Western Esotericism means so many things to so many people, it can be challenging to a new learner interested in the subjects contained therein.
Symbolism might best be considered in terms of revealing and re-veiling. The veil is the protective covering shielding the sacred from the profane, and therefore higher vision can be revealed only to inspired perception. It has always been the task of the initiate to attain this higher vision.
