Egil Asprem Aries 17.1 (2017) Pre-Print 1 Explaining the Esoteric Imagination: Towards a Theory of Kataphatic Practice Abstract: The imagination is central to esoteric practices, but so far scholars have shown little interest in exploring cognitive theories of how the imagination works. The only exception is Tanya Luhrmann’s interpretive drift theory and related research on mental imagery cultivation, which has been used to explain the subjective persuasiveness of modern ritual magic. This article draws on recent work in the neuroscience of perception in order to develop a general theory of kataphatic (that is, imagery based) practice that goes beyond the interpretive drift theory. Mental imagery is intimately linked with perception. Drawing on “predictive coding” theory, I argue that kataphatic practices exploit the probabilistic, expectation-based way that the brain processes sensory information and creates models (perceptions) of the world. This view throws light on a wide range of features of kataphatic practices, from their contemplative and cognitive aspects, to their social organization and demographic make-up, over their pageantry and material culture. By connecting readily observable features of kataphatic practice to specific neurocognitive mechanisms related to perceptual learning and cognitive processing of mental imagery, the predictive coding paradigm also creates opportunities for combining historical research with experimental approaches within the study of religion. I illustrate how this framework may enrich the study of Western esotericism in particular by applying it to the paradigmatic case of “astral travel” as it has developed from the Golden Dawn tradition of ritual magic, especially by Aleister Crowley. Keywords: mental imagery; predictive coding; interpretive drift theory; kataphatic practice; astral travel. 1. Introduction: Explaining the Esoteric Imagination Practices that aim to produce subjectively powerful experiences are commonplace in the history of esotericism. From conversations with angels through crystals and erotic encounters with Divine Sophia, to adventures on the astral plane and the channelling of ascended masters from the Pleiades, esoteric practitioners often seek special knowledge through intimate experiences with mediators. Scholars have long agreed that “imagination” is central to these practices, and it has even been suggested that the imagination is a defining characteristic of esotericism itself. 1 Wherever one stands on the issue of 1 Faivre, Access to Western Esotericism, 12.
