The aim of the paper is: a) to gain some knowledge of the so-called ‘natural systems’ as interpreted or defined by modern systems scientists; b) to discuss these descriptions and definitions from the viewpoint of modern philosophy of science. In the course of both a) and b) the interwovenness of the classes of natural systems and the controversial issues connected therewith (a.o. their interwovenness with the artificial systems) will be touched upon.
