QUOTE : Nature is both passive and active, product and productivity, but a productivity that always needs to produce something else (for example, human generation, which ceaselessly repeats without end). There is a double moment of expansion and contraction, which Lowith compared to respiration, which never goes to the end of its movement except in death, and which designates the character of a relative production as always begun again. Nature is beyond the World and on this side of God, and as such, Nature is neither God nor World. It is a producer that is not all-powerful, which does not succeed in ending its production: it is a rotary movement that produces nothing definitive. There is a general 'duplicity' of Nature as necessary as Nature itself is. If productive Nature were withdrawn from the product, it would mean only death.
