"The idea of a systems can be seen as a further generalized and extended thought of the following consideration. First, there is the rather sweeping claim, that "Every system has subsystems". Taking this together with "Every system has its environment", we are indeed confronted with limitless vistas of systems. One us unable to think of anything, or of any combination of things, which could not be regarded as a system. And, of course, a concept that applies to everything is logically empty. What characteristics are there which any object or group of objects could have, such that they would fail to form some kind of system? In my view, general systems theory not only does not, but further could not, answer this question. And it is partly for this reason that I believe that general systems theory is not in fact science at all, but rather naive and speculative philosophy."
