Contrast "complicated" where plic (meaning "folded") refers to many layers.A complex system is thereby characterised by its inter-dependencies, whereas a complicated system is characterised by its layers.In Weaver's view, disorganized complexity results from the particular system having a very large number of parts, say millions of parts, or many more.
The source of disorganized complexity is the large number of parts in the system of interest, and the lack of correlation between elements in the system. Complexity of an object or system is a relative property.
From one perspective, that which is somehow complex – displaying variation without being random – is most worthy of interest given the rewards found in the depths of exploration.
The use of the term complex is often confused with the term complicated.
The organized aspect of this form of complexity vis-a-vis to other systems than the subject system can be said to "emerge," without any "guiding hand".
The number of parts does not have to be very large for a particular system to have emergent properties.
