Introduction Disenchantment and Integrative Postmodernism Keiron Le Grice This issue of Archai is concerned, in broad terms, with the rise of the disenchanted world view in the modern era and the possible significance of archetypal cosmology for moving beyond it. Disenchantment and Desacralization Disenchantment is a term employed by Max Weber to describe the world view of modern secular society in which, as he puts it, “no mysterious incalculable forces come into play”—a world view in which recourse to mysticism, supernatural powers, gods and goddesses, spirits, and magical explanations is considered both unnecessary and invalid.
