The German filmmaker Werner Herzog controversially associates “truth” and “reality” in film with Kant’s notion of the sublime by explicitly treating the sublime as a key element in developing his notion of ecstatic truth. I critically examine Herzog’s interpretation of Kant’s sublime and the relations he establishes between the sublime and his own key aesthetic notion of ecstatic truth. I examine how the sublime in Herzog’s films arises from encounters with the overwhelming force and power of nature experienced by his (...) characters in the feature films and participants in the documentaries. I question whether Kant’s conception of the sublime is the one that best aligns with Herzog’s aesthetic aims and I contrast Kant’s transcendental sublime with what I describe as the physiological sublime of Edmund Burke. I draw some conclusions about the moral dimension of the sublime in the context of the relationship between humans and nature within the frame of contemporary ecological concerns. (shrink)
