IN SETTING THE BASIS for his philosophical system in the monumental Critique of Pure Reason, Immanuel Kant demarcated between intuition (Anschauung) and sensation (Empfindung). Anschauung is the intuition, or knowledge, that results from the immediate apprehension of an independently real object, that is, a concept in Kant's philosophy. Whereas etymologically Anschauung refers only to visual sensations, Kant extended its applicability to cover any sort of perception. Kant's goal was to develop the notion of the reine Anschauung of space and time, and for this purpose the term "pure sensations' would not do.
