“Nature does not teach. A true philosophy may sometimes validate an experience of nature; an experience of nature cannot validate a philosophy. Nature will not verify any theological or metaphysical proposition (or not in the manner we are now considering); she will help to show what it means.”

“Historically, philosophy does not have an impressive track record of answering questions about natural world in a decisive manner.”

“Sometimes nature cannot stand us. And Sometimes we cannot stand our own nature.”

“The natural world is the only reality, thus the only valid base for spirituality there is.”

“If anything in Kafka's 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 for man. There may, however, be more modern reasons for the absence of this concept in Kafka's case. His position here resembles that of Heidegger, 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.”

“In order to live, man must act; in order to act, he must make choices; in order to make choices, he must define a code of values; in order to define a code of values, he must know what he is and where he is – i.e. he must know his own nature (including his means of knowledge) and the nature of the universe in which he acts – i.e. he needs metaphysics, epistemology, ethics, which means: philosophy. He cannot escape from this need; his only alternative is whether the philosophy guiding him is to be chosen by his mind or by chance.”
