It is obvious that the World is the largest and most complex system. It is obvious that the essence of the World cannot be known without analysing it as a system. System (gr. system - connected, composed of parts) – a collection of elements components) that are interconnected by certain connections; this forms a whole in one form or another. The whole can be understood quite differently (various contexts), but basically, three important moments can be distinguished: a system as a certain whole (a certain organised and interacting set of components, performing a certain function (s) and having a purpose (s)), a system as philosophy (simply all things in the world are connected), a system as technology (technological system or systems act as certain entities). Of course, the goal here is not to discuss deep methodological issues of systematics (systemology).
