The human sensory and cognitive system, according to the German scholar Johan Lindner of Mönchenburg. Illustration to a manuscript copy of Aristotle’s De Anima (1472-1474), courtesy of the Wellcome Collection (MS 55).
I’ve recently been reading up on medieval theories of cognition. The background is a paper I’m writing on esotericism and “kataphatic practices” – contemplative techniques where the practitioner uses mental imagery, sensory stimuli, and emotions to try and achieve some religious goal: Prayer, piety, divine knowledge, salvation, etc. Kataphatic practices may be distinguished from “apophatic” ones, which, although they may be pursuing the same goals, use very different techniques to achieve them: withdrawing from sensory input and attempting to empty the mind of any content, whether affective, linguistic, or imagery-related (note that the kataphatic-apophatic distinction is more commonly used as synonymous with positive vs. negative theology – that’s a related but separate issue to the one I talk about here). My argument is that esoteric practices are typically oriented toward kataphatic rather than apophatic techniques. The cultivation of mental imagery is usually key – which means that the notion of “imagination” needs to be investigated more thoroughly.
