...it would be a very naive sort of dogmatism to assume that there exists an absolute reality of things which is the same for all living beings. Reality is not a unique and homogeneous thing; it is immensely diversified, having as many different schemes and patterns as there are different organisms. Every organism is, so to speak, a monadic being. It has a world of its own because it has an experience of its own. The phenomena that we find in the life of a certain biological species are not transferable to any other species. The experiences - and therefore the realities - of two different organisms are incommensurable with one another. In the world of a fly, says Uexkull, we find only fly things; in the world of a sea urchin we find only sea urchin things.

A dying organism is often observed to be capable of extraordinary endurance and strength. ... When any living organism is attacked, its whole function seems to aim toward reproduction.

Every living organism is fulfilled when it follows the right path for its own nature.
