Present-day life is polluted at the roots. Man has put himself in the place of trees and animals and has polluted the air, has blocked free space. Worse can happen. The sad and active animal could discover other forces and press them into his service. There is a threat of this kind in the air. It will be followed by a great gain…in the number of humans. Every square meter will be occupied by a man. Who will cure us of the lack of air and of space?

La coscienza di Zeno (1923)
