If anything in theology can be called Jewish, it is his virtual lack of any concept of 'Nature'. There is in a sense no 'Nature' in Genesis either, since the world is created man. There may, however, be more modern reasons for the absence of this concept in Kafka's case. His position here resembles that of , whose Existential philosophy represents an attack on Naturalism (while adopting its atheistic presuppositions) and therefore finds no place for nature as such, but only for the world in so far as the world exists 'for human existence', i.e., as 'material'. Heidegger and Kafka are radically original in that aspect of their thought which does away with the natural and the supernatural at the same time. In Kafka the absence of Nature is due to the fact that for him what might be termed the 'institutionalization' of the world is total, indeed totalitarian. There is no room in it for that unoccupied and unused space beyond the sphere of human needs which we are in the habit of revering or enjoying as 'Nature'. Yet there is truth in Kafka's omission of Nature from his world, to the extent that the mechanized civilization of to-day may be described as appropriating and exploiting everything there is as raw material or fuel, and destroying whatever cannot be exploited—even human beings.
