La scienza degli spiriti: Prospettive sull'anima separata da Leibniz a Kant

Kant sometimes characterizes spirit as a thinking being that is able to exist even without a body, and he claims that this concept sustains the ambition of rational psychology to develop into a science of spirits or pneumatology, understood as the doctrine that investigates the otherwordly state of separated souls. Who were the upoholders of this spiritualist view of the mind? Though dismissed by some as expression of a generic Leibniz-Wolffian philosophy, the claim that disembodied spirits exist is, in fact, the very issue on which not only Crusius but also Wolff himself radically parted ways with Leibniz and moved back to Cartesian positions.
