Abstract

Oswald Külpe’s original interpretation of Kant’s philosophy influenced Külpe’s own philosophical thought. On the one hand, Külpe is critical of his illustrious predecessor. For him, in fact, Kant wrongly denies that human thought can address itself to truly non-intuitive objects; furthermore, his transcendental aesthetics is utterly misleading. Interestingly, both claims are supported by Külpe with reference to the psychological research of the time. On the other hand, however, Külpe is highly sympathetic with one of Kant’s central assumptions, namely the unreliability of the internal sense. Against Wundt and other psychologists of his time, Külpe conceives of the epistemological foundations of psychology in accordance with the rehabilitation of this Kantian claim.
